Demona pondered over the last pages of her newly-published paper, "The Futanari Penis: An Analysis of the Male Sexual Genitalia of Futanari Subjects", as she sat at her desk in her bedroom. A great amount of work had gone into this study, considering that she was the only one who wrote the paper, but she couldn't have been more proud of her work.
 
Over three thousand futanari subjects, some of whom were her close friends, had offered their dicks for a comprehensive analysis of futanari genitalia. After three months, Demona had recorded all of the numbers that she needed and was able to generate all the graphical analyses she could.
 
She'd found a few interesting pieces of information within the results. The linear R-value of the scatter plot of average length (erect) and average time to orgasm (physical stimulation) was 0.519, and the slightly-increasing trendline showed that longer erections took slightly longer to orgasm. Demona had theorized that the length of the dick might mitigate the stimulation slightly and therefore contributed to the correlation found in the graph.
 
The succubus sat back and exhaled. She'd authored so many papers on her own on the subject of futology, such as her most cited paper, "Loads of Loads: A Study of How Fetishes May Alter Semen Production in Futanari Subjects", which shed light on how electrocution tended to decrease the volume of an orgasm by an average of 12%, while prostate stimulation, of course, increased the volume by an average of 45%.
 
Sure, being a professor at 4chan University with a Ph.D in futology and a Masters in fetishology was cool, what with the great salary and the joy of widening her understanding of her expertise (so that she could apply it to her own "subjects"), but she longed for more.
 
Demona picked up a notepad and a pen and set to work. She needed new research ideas. Looking at the summary from her paper, which was now resting on her desk, she wrote down a few key words and phrases: "orgasm", "semen", and "time to orgasm".
 
Mulling over the three entries in her list, Demona began to formulate an idea. Thinking hard, she drew on one of her lesser-used fetishes and began to smile. She eagerly flipped over to a new page and began to write down her new idea.
 
"In Denial: Utilizing a Practical Case Study to Test the Limits of Futanari Orgasm Denial.
September 12, 2017, 8:42pm: Idea gained after brainstorming. Plan of attack - Bring in a special subject who will be able to withstand the methods I am willing to apply to her. Subject must have the following traits: Impossible to physically harm, must not be able to feel any sort of distress or pain, must have extreme (really, really extreme) elasticity and be able to put her body to the toughest of tests, must be of normal/average human stature and between the ages of 18 and 29, must be basically immortal."
 
Smiling devilishly, Demona leaned back in her chair and chuckled. The traits of the "special subject" seemed incredibly farfetched and downright impossible to find in any person. However, this was 4chan, not the real world. Out there, there was a subject who was impervious to harm, pain and death, super-abnormally resistant, and yet, she was still a normal woman. And it just so happened that Demona was good friends with a woman just like that...



"I'm so excited!" Keksandra exclaimed, prancing about on her toes as she entered Demona's laboratory. She'd been giddy ever since the succubus had called and asked her about participating in a special scientific experiment, to which she'd delightedly agreed. "I'm gonna be in a science book thing and all the other science people will read it and I'll be a famous science person!"
 
Demona smiled, enjoying the positive energy of the twenty-two year old, who was also a time-to-time subject of her own lewd escapades. She grabbed a voice recorder out from her pocket and pressed the 'record' button on it.
 
"11:29am: Subject has arrived. Subject is energetic, excited, upbeat. Will commence taking measurements and checking her arousal state," she said into the recorder.
 
Pocketing the recorder, Demona clicked her heels on the floor and cleared her throat. "Ahem, Keksandra, attention," she ordered. The woman immediately stood still, staring goofily at Demona. "The first course of actual is to gather some vital statistics. Please undress and step over here for measurements," she explained.
 
Finding absolutely nothing wrong with what Demona said, Keksandra eagerly kicked off her flats, tossed her hat aside, slipped out of her dress and removed her undergarments in typical Keksandra fashion.
 
"All done! I'm still wearing a suit, though!" she proudly declared.
 
Demona cocked an eyebrow. "That wouldn't happen to be your birthday suit, would it?" she asked.
 
"Awww, you're no fun. But that's okay! I like to wear my birthday suit," Keksandra giggled, her voice transforming into a cheerful melody, "'cause that's the way I like to live my life, and I know that everything's gonna be just fine!"
 
The succubus focused on taking measurements as Keksandra continued to sing about a man supposedly known as "Steve" (though she repeatedly mentioned that Steve wasn't his real name). It took a mere five minutes to gather all the necessary measurements.
 
"11:36am: Measurements taken. Height: Six foot six inches. Weight: One hundred and fifty-five pounds. Age: Twenty-two. Gender: Female. Cup size: Double D."
 
"I'm a big girl, for you!"
 
"Commencing measurement of subject's state of arousal," Demona added, placing her voice recorder on the table beside her.
 
She moved behind Keksandra and placed her hands on her shoulders, burying her nose into the woman's hair and inhaling. Keksandra giggled feverishly and closed her eyes. "D'ya like my new shampoo? I got it in real Topkek smell!" she said, her breasts jiggling ever so slightly as she laughed. "I'm, like, a million percent Topkek!"
 
Demona traced Keksandra's curves and gave her breasts a little squeeze. "If you're unsure of what I'm doing here, don't be concerned," she explained, in case she was making Keksandra slightly uncomfortable. "This is just standard procedure for this study."
 
"Oh, that's okay! I like what you're doing, it tickles!" the brown-haired woman replied, placing her hands on her breasts. "I like how big my boobs are now, and they're all bouncy and jiggly. Sometimes the other boards like to touch them and I like it when they do that! You're, like, the first girl who's touched them, though! Well, not really. My wifey Ingrid likes to squeeze them and my friend Emily used to play with my boobs a lot when we were dat- OOOOOH!"
 
While Keksandra had been blabbering on and on about her breasts and who got to touch them, Demona had stuck one of her fingers deep into her cunt. She moved the appendage around the inside of her nethers, checking how they reacted to her touch. Keksandra panted heavily, her tongue flopping out of her mouth.
 
"Demonaaaah is this whaaaaat you do in sciiieeeeenceee..." she groaned, tightening up on Demona's fingers as the succubus squeezed another one into her pussy.
 
"Of course it is, Keksandra," Demona said matter-of-factly, biting her lip as she felt a wet squelching around her fingers. "When you have degrees in futology and fetishology, this becomes part of your day job. You might like to consider attending this university."
 
Keksandra felt a warm wetness snaking down the inside of her leg. "I wannaaaaaa get a degreeeeee ohhhhhhhhh...in meeeemes..." she wheezed.
 
Demona withdrew her fingers and examined them, satisfied with Keksandra's arousal. "Alright, it looks like your state of arousal is in great condition, just what I need for this study," she explained, licking her fingers clean and grabbing the voice recorder again. "11:39am: Physical analysis of subject's state of arousal completed. Subject's state of arousal is perfect. Miscellaneous note: Subject's vaginal discharge tastes like the Turkish snack Topkek. Commencing succubus-assisted addition of futanari genitalia."



"11:48am: Measurement of substance for ingestion in order to perform succubus-assisted addition of futanari genitalia complete," Demona commented into her recorder, disposing the tip of her autopipette into a waste container. She lifted the test tube out of the rack and showed it to Keksandra, who sat on one of the chairs in the laboratory.
 
"Now, Keksandra, what I have here is a substance that I synthesized last year as part of a previous study," Demona explained, gaining the woman's immediate attention. "This is demonafutine, or in IUPAC terms, 3,3,4-tripropyl-1,5-dibutylisodec-4-ene."
 
Keksandra cocked her head, little question marks appearing out of thin air around her.
 
"The official name is long, but that's what shortened names are for, and I had the honor of giving it the name 'demonafutine', after my own name," Demona continued. "Now, this substance is quite remarkable, Keksandra. It remains in the stomach if ingested and can not be broken down by the gastric acid inside. However, it can react with the seminal fluids of futanari women, like me.
 
"The products of the reaction are then able to react with the gastric acid, and the products of that reaction will alter your hormones and rapidly cause specific proteins to be synthesized by your cells. These proteins will cause rapid cellular reorganization around your labia, uterus and vagina which, combined with the hormones, will result in the growth of a futanari penis."
 
Keksandra stared blankly at Demona, not understanding any of the big words she said. "Eh?" she asked.
 
Demona cleared her throat and explained it again. "This, plus futanari semen, plus digestion, equals you getting a penis."
 
"Ohhhhhhh! So I drink it and I'll get a benis? Awesome!" Keksandra squealed, jumping off of the chair and bouncing around excitedly.
 
"That is the plan, Keksandra," Demona confirmed, giving Keksandra the test tube and placing her hands on her hips. "Now, demonafutine has a sour taste, so try to swallow it immediately."
 
The woman looked into the test tube, seeing the thick, pink fluid inside of it. Wearing her trademark goofy smile on her face, she put the test tube to her lips and swilled the contents in one go, gulping it quickly. She coughed and stuck her tongue out.
 
"Blegh, sour!" she complained. Demona took the test tube from her and placed it in the test tube rack, mentally reminding herself to thoroughly clean it after Keksandra was settled down for the study. She watched the woman trying to 'air' the taste of the demonafutine off of her tongue, though she had little success in doing so.
 
Keksandra remained where she was, placing her hands on her stomach and squeezing it. "Oh yeah, I gotta get the girlpenis semen stuff! That comes from the girlpenis, right? And you have a girlpenis! Am I gonna have your girlpenis semen?" Keksandra asked.
 
Demona strolled back to the woman and grinned, feeling the all-too-familiar sense of excitement between her legs. "Well, I don't see any other candidates around here who have a 'girlpenis', do you?" she asked, her dominant hand unzipping the zipper on the back of her leather skirt. She waited for the skirt to fall down to her ankles, and then remembered the obvious bulge underneath it that was keeping it up at her hips. Sighing, she tugged the skirt down, feeling it crumple on top of her heels.
 
The succubus's double dick, now out of the confines of the skirt, stiffened up in the cool air. Keksandra looked down and squealed under her breath. She'd ridden that thing before, and on many occasions, with one dick up her cunt and the other, usually the bigger one, plowing her ass. It wasn't often that she'd find one, or even both, in her mouth.
 
"Check 'em! Nice dubs, Demona!" Keksandra cheered, sticking out her index finger and pointing at her junk.
 
"Thank you, dear. Now, on your knees and open up. Aunty Demona's gotta get the reaction going," the succubus ordered. Keksandra obeyed her, getting down on her knees and widening her jaws. Her hands found the professor's firm buttocks and gave them a little squeeze, much like Demona had done to her breasts earlier.
 
Demona stared into Keksandra's mouth, her cocks hardening up further as she looked deep into the inviting, hot throat that would soon be hosting her erections. She grabbed a handful of Keksandra's hair and inched her dicks into the maw, the bottom dick squishing up on her tongue and her top dick grazing her front teeth...
 
...and in one fluid movement, she slammed Keksandra's head into her abdomen, surprising the woman as her huge dicks forced themselves down her throat.
 
"Aaaahhn, fuck, that was great," Demona huffed. She looked down at Keksandra, who didn't appear to show any sort of discomfort, despite her gullet being completely blocked. "You okay? I didn't force it too hard, did I?"
 
Keksandra closed her eyes and shook her head. "Hmmmmph mmm-nn fmmm, mmm!" she tried to say, her voice muffled.
 
Demona shuddered, as the vibrations of the woman's throat and the movements of her tongue were sending shivers down her spine. "Guh, why is your tongue so fucking hot..." she mumbled under her breath, humping forcefully.
 
Out of all the mouths Demona had fucked senseless, she couldn't deny that Keksandra's was absolutely the best of them all. Her talkative personality meant that she would try to talk when she was getting facefucked, and the way her sloppy, huge tongue and tight, wet throat moved around her cocks as she did so drove her wild. So wild, sometimes, that she'd only last seconds before pumping her stomach full of spunk.
 
"Talk to me, babe..." Demona groaned, pulling Keksandra's hair harder and harder. She loosened her grip, fearing that she might accidentally rip out some of the soft, brown locks on accident. "Sing a song for meeee..."
 
Keksandra looked up and, well, tried her best to smile with a mouthful of dicks. "Mm-hm! Mmmm mm-mm-mm mph-mph-mph-mph, hm-hm-hm-hm-hm...mm-mm-mm-mmmmmm hm-hm-hm HM HM, hm-hm-hm-hm mm-mm-mmph mm-mm-mm MM MM!" she sang.
 
Demona thought she could hear Smash Mouth's "All Star" and that "hi, i'm steve" song she'd heard repeatedly when Keksandra was being measured. Whatever she was singing, it was enough for her to peak. Feeling her large balls drawing up into her groin, Demona refused to hold back as she blasted a huge load of cum straight down Keksandra's throat.
 
While most of the semen shot down Keksandra's throat with such force that it passed into her stomach immediately, some of the load went elsewhere. With her mouth completely blocked, semen began to get forced up the back of her throat and into her nasal cavity. Keksandra felt the thick gunk flooding into her nose, where it started squirting out of her nostrils like a fire hose.
 
While many would have been struggling to breathe, Keksandra only found it to be a minor inconvenience. She was too focused on the amazing torrent of cum that was pumping into her gut. Eventually, some drops of the thick spunk splashed onto her tongue, giving the woman the familiar salty taste of Demona's goo.
 
Demona flexed and forced out a few more squirts of cum as she pulled out of Keksandra's mouth, spraying the last of her load all over Keksandra's face, hair and breasts. Her breathing was very ragged and she was sweating profusely, even though she had only been at it for two minutes.
 
"My...GOD...that was amazing..." the succubus huffed.
 
Keksandra put a hand to her cheek and scraped up a handful of cum, licking it off of her palm eagerly. "Mmm, your seed's still super salty and delicious, Chuck!"
 
Demona raised an eyebrow. "Who's Chuck?"
 
The woman giggled. "You are! Your name is Chuck, and his brother is Sneed! He runs Sneed's Feed & Seed, formerly Chuck's! I like your business, Chuck!"
 
"Oh, you little scamp, you've been hanging around /tv/ a little too much lately, haven't you?" Demona asked.
 
"He's a big guy, for me! Buuuut, you're a bigger grill, also fooooooooohhhh my bagina :DDDDD"
 
Keksandra and Demona both looked down at the former's cunt, or, where the former's cunt formerly was. The reaction in her stomach had already taken effect and the rapid cellular organization was now taking place. A small knob-shaped shaft was rising out from where Keksandra's vagina once was.
 
As seconds passed, the shaft grew and became more defined. The loose skin at the end of the shaft parted and revealed a shiny pink tip. Underneath the shaft, Keksandra could feel a little sac of skin growing there. She carefully prodded the sac, feeling two solid sphere-shaped organs moving around inside. Her shaft began to stiffen up slightly, veins protruding along the skin.
 
The feeling in the organ was alien to Keksandra, but it felt great. Her futanari cock wasn't finished developing, and it already had a solid erection. The feeling was getting more intense as the dick finally stopped growing, sticking out towards Demona, the pink tip flaring angrily and begging to be touched.
 
"Fuuuuug...the benis feels awesome..." she moaned.
 
Demona retrieved her voice recorder from her jacket pocket and began to record again.
 
"11:59am: Succubi-assisted addition of futanari genitalia complete. Will now proceed to measurements and performing mandatory checks to confirm that it is in working order," she spoke.



Demona held out the measuring tape in one hand and placed one end at the base of Keksandra's cock, which had been placed in an induced flaccid state with a two-minute testosterone blocker. Using one of her hair tentacles, she gripped the other end and measured out the softened shaft, which rested on her desk.
 
"5.91 inches, bigger than the average," Demona mumbled, writing down the measurement with her free hand. She wrapped the measuring tape around the thickest part of the dick, measuring the girth. "Aaaaaand 4.65 inches, also bigger than the average..."
 
Keksandra felt like she was being tortured, though to be fair, she did tend to over-exaggerate things. "Demonaaaaa, I wanna make my benis go big again, you're teasing meeeee!" she moaned.
 
Demona smiled. "Well, honey, you're in luck. The drug will wear out in a few seconds," she chuckled, opening one of the drawers in her desk and retrieving a stopwatch. "Now, I need to time your erection for mental and physical stimulation."
 
"I don'd ged id."
 
The succubus sat back and held the stopwatch in her hand. "We're going to start with mental stimulation. Start thinking about something that makes you feel good down there," Demona ordered, her thumb poised on the stopwatch button. "The second you feel like you're getting an erection, say so."
 
Keksandra took a deep breath and closed her eyes, concentrating on a certain fetish that often made her feel hot and bothered, and gave her joyous pleasures in secrecy when she fingered herself in her bedroom.
 
"G-go!" Keksandra yelled.
 
Demona clicked the button on her stopwatch and watched Keksandra's cock with intent. Almost immediately, it began to stiffen up and lift off of the desk. The succubus raised her eyebrows in surprise. She'd tested over three thousand futanari subjects in that previous study, and Keksandra was on track to having one of the fastest mentally-stimulated erections.
 
Patiently waiting for the boner to stop rising, the succubus immediately pressed the button on the stopwatch, concluding the measurement.
 
"My goodness, Keksandra," Demona commented. "That was only 24.39 seconds! And that was just your head doing the work!"
 
Keksandra smiled, her tongue flopping out over her bottom lip. "Having a bepis feels greeeeaaaaat..." she groaned.
 
Demona grabbed the bottle of testosterone-blockers from her desk and removed one pill, giving it to Keksandra. "Now, take another one of these so that we can start the physical stimulation test in a few minutes," Demona ordered.
 
Whining sadly, Keksandra swallowed the pill and stood still. In just a matter of seconds, she watched disappointingly as her hard, erect cock softened up and flopped down, the blockers acting on her virtually instantly.
 
"You know, I'm quite curious," Demona said, "as to what you were thinking when you pulled that off."
 
"Huh?" Keksandra asked, not quite understanding what the succubus meant.
 
"Oh, it's a question that I ask all my subjects who manage a mentally-stimulated erection under 25 seconds," Demona explained. "I feel like their secrets may be helpful in the future, should I pursue a more psychological branch of my expertise. Of course, you don't have to reveal your thoughts, you can keep it secret if you wish."
 
Keksandra blushed slightly and tapped her chin with her finger, her other hand clenching into a balled fist. "I-I kinda, like, have this weird thing with clothes..." she began to say.
 
"Clothes?" Demona thought, smiling. "Interesting..." She raised one eyebrow, prompting Keksandra to continue talking.
 
"...and I kinda like it when I, uh, I swap MY clothes with another girl, who I really wanna fug," the woman said, giggling not-so-innocently. "It's reeeaaaaally weird, like, maybe I wanna fug that girl but I wanna be the girl and get fugged by the girl being me..."
 
Demona scribbled the thoughts down in her notepad. "Mm-hm, sounds like you're into some role-reversal domination, perhaps?" the succubus asked. "That's quite an interesting kink, Keksandra."
 
Keksandra's blush was covering her whole face. "H-he-he, it's weeeeird..."
 
"No time for weird, Keksandra. The physical stimulation tests start now, and the erect measurements will come next," Demona ordered. "Please hold your dick and pump it along the shaft. As soon as you start to feel it getting hard, say so..."
 
 
 
"12:13pm: Futanari measurements complete. Flaccid length: 5.91 inches. Flaccid girth: 4.65 inches. Erect length: 14.78 inches. Erect girth: 10.82 inches. Flaccid to erect via mental stimulation: 24.39 seconds. Flaccid to erect via physical stimulation: 14.91 seconds. Will proceed to testing orgasm," Demona spoke into her recorder.
 
Demona grabbed her stopwatch and placed her voice recorded down on her desk, strolling to Keksandra with a devious grin on her face. She looked at the woman with glee, seeing her fully-hardened shaft pointing directly at the succubus.
 
"Okay, for this part of the study, I'm going to measure your orga-" Demona began to say.
 
"Waaaait!" Keksandra interrupted.
 
Demona paused, waiting for Keksandra to speak.
 
"C-can we...do my clothes thing pleeeaaaase?" she asked innocently.
 
The succubus stood still and pondered the woman's request. Within a few seconds, she smiled and walked back to her desk, placing the stopwatch down.
 
"Well, I don't see why not," Demona agreed, unbuttoning her dark red suit and tossing it over her shoulder. "If you desire making this study more enjoyable for yourself, then I am very happy to oblige." She unzipped her black leather skirt and pulled it down, kicking it behind her. "Although, I must admit, I was hoping to try it out with you."
 
Keksandra gathered up the skirt and used one hand to push her erection down. "Really? You like it?" she asked, dragging the skirt up her thighs.
 
"Of course I like it. You seem to be forgetting that I AM Demona, right?" Demona chuckled, lifting her black tank top, which was leather on the top half and elastane on the bottom half, up over her head until she could toss it to Keksandra. She supported herself on her desk and she pulled off her black pumps. "I'm pretty much the Glenn Quagmire of this university."
 
Keksandra smiled. "Hehehe, Family Guy funny moments!" she giggled, grabbing the pumps from Demona. "Hey 🅱eter! Yes Elmo from Sesame Street? Spell WHOMST'VE!"
 
Demona picked up Keksandra's clothes and gave the dress a deep whiff while Keksandra was struggling to get Demona's tank top over her chest. She pancaked the dress in her hands and stuck her head through it. Putting the dress on was as simple as placing her arms underneath the straps and letting gravity unfurl the dress all the way down to her knees. Though Keksandra and Demona were the same height and the dress normally went down to Keksandra's ankles, it was thanks to Demona's much larger breasts that gave the free-flowing outfit the appearance of a typical knee-length dress.
 
As Demona slipped on the woman's flats and set her trademark Top Kek hat on her head, Keksandra finished putting Demona's pumps on her feet. She tried to stand up straight, but her unfamiliarity with heels caused her to fall on her backside.
 
"Not really much of a heels person, are you?" Demona asked.
 
Keksandra blew a raspberry. "They feel like walking on tippy-toes," she said, maintaining her golden smile. She noticed Demona's breasts stretching out her dress a bit, as well as the obvious double-bulge in front of her face. "D'ya like my clothes? They're so awesome, aren't they?"
 
Demona pinched the hem of the dress and placed a hand on her hip. "Well, it's very different from the casual attire that I've grown accustomed to," she thought aloud, "but I must say, I would wear something like this for a nice walk in the spring."
 
The succubus looked at Keksandra and knelt down, lifting her up and setting her down on her feet. "Juuust remain still and you won't fall..." Demona said. "So, do you enjoy my work outfit?"
 
Keksandra smiled brightly. "Uh-huh! I feel like a professional person! Like Donald Trump, or Brombuld Drumpf, or Zgronald Bllllumpf!" she exclaimed. "I don't know what his real name is, but /pol/ keeps complaining about him. He says he gets to have two scoops of ice cream and that the Drumpf man says he'll get him peach! Maybe /pol/ likes peach ice cream!"
 
The succubus couldn't help but chuckle at Keksandra's naivety. It was just so innocent.
 
"Well, I believe you're in need of stimulation again, aren't you?" Demona asked, slowly walking back to her desk to grab her stopwatch.



"12:18pm: Commencing testing of orgasm. Subject will be tested while experiencing a sexual desire to help with the process," Demona spoke into her voice recorder, before placing it on her desk. She grabbed her stopwatch and her special orgasm collector and sensor and walked to Keksandra.
 
The woman was already aroused now that she was ready to try out her new dick while switching clothes with Demona. She hugged her raging erection close to her body and groaned happily, feeling her organ rubbing up on the leather of the skirt and tank top. She stuck out her tongue and managed to tickle the tip of the cock.
 
"With a little flexing, you might be able to stick it down your throat," Demona commented, getting down on her knees. Keksandra noticed the mass of tubing in her arms.
 
"What's that, Octopus Girl?" she asked.
 
Demona held the container in one hand and moved her other hand down the flexible tubing, eventually reaching the funnel at the end of it. "This is a special machine that has been made available in this field," the succubus explained. "This is called an orgasmometer, and it is a wonderful contraption that has made futology studies much easier."
 
Keksandra sat up with interest, the pumps on her feet clicking as they hit the floor. "What's an orcas-mom-meter do? Does it measure Bepsi stuff?" she asked, noticing the electronics on the canister attached to the tubing.
 
"Check out the big brain of Keksandra," Demona complimented, pressing a few buttons on the canister. "You're a smart girl, it does measure stuff."
 
"What does it measure?"
 
Demona clicked a few more buttons on the canister and set it down. "The orgasmometer measures many aspects of a sample orgasm from a subject," Demona explained. "Such measurements include the volume of the subject's orgasm, the individual releases of semen in the orgasm, the length of time that the orgasm lasted, the length of time that it took to achieve orgasm, and the properties of the semen contained. I'll be able to use these as pre-experiment measurements and compare them to the post-experiment measurements, while also confirming that your penis functions perfectly."
 
"And then we can do the awesome study and I'll be famous!" Keksandra cheered, kicking her legs up and down excitedly.
 
Demona smiled. "That you will, and that you will be," she sighed contentedly, activating the vacuum of the canister. A wooshing sound could be heard from the funnel of the tubing as air was sucked into the canister.
 
Grasping the shaft of the funposter's cock, Demona placed the funnel on the tip of it and watched as the head of the penis fit into it. Keksandra groaned, her fingers tightening as she grasped onto the hem of the leather skirt.
 
"This vacuum will ensure that every last drop of your orgasm is collected," Demona said, crawling behind Keksandra. She pulled the dress up and freed her double bulges from the confines of the purple fabric. Her other hand reached down and tugged Keksandra's skirt up, revealing her plump bottom.
 
The succubus's strong arms lifted Keksandra up, holding her as she shuffled around to line up her bottom cock with the woman's asshole. Keksandra bit her lip as she felt the tip of Demona's dick poking her entrance. With a little more force, Demona's cock broke through the tight ring as she let gravity do the rest, feeling Keksandra land in her lap.
 
"Hyoh-h-h-h, fug yeah!" she groaned, the familiar pleasure of being anally-penetrated returning to her. She felt her cock stiffen up even more from the pleasure, and even more so as Demona's strong, manicured hand grasped her throbbing erection.
 
Demona gently stroked the shaft up and down as she heard a small "beep" from the canister, indicating that it had detected the first signs of stimulation, therefore activating the internal stopwatch in order to time the stimulation before orgasm was achieved. She dragged Keksandra closer, feeling her other cock being squeezed up between them.
 
Forcefully, the succubus humped Keksandra, pounding her ass over and over while she pumped the dick in her hand. As she moved, both of her cocks felt different kinds of ribbed pleasure. The one plugging Keksandra's ass enjoyed the familiar feeling of the lubricated walls of her rectum, while the one in between the two girls was being smothered through the creased fabrics of Keksandra's dress, and her skirt and suit.
 
Grabbing Keksandra's breast with her free hand, Demona squeezed the soft orb through her own tank top, feeling their natural springiness and resistance. She reached down the cleavage and played with one of her nipples, circling and pinching it gently. She grew harder as she heard the woman's high-pitched squeals.
 
"My-y-y-y-y bepiiiiis feel EEEEEEBIIIIN~" Keksandra groaned. "Fu-u-u-ug me harder-er-er-er-er Keksandraaaaa~"
 
Ah, of course. A little roleplaying.
 
Demona cleared her throat and tried to put on a convincing falsetto voice. "Heeeey, tentacle lady!" she mimicked, albeit poorly. "You've got a nice butt! I like putting my bee-piss in it!"
 
Even though her voice was way off, Keksandra decided to return the favor. She tried to lower her voice and put on some sort of high-class accent. "My, my, myyyyyyy...Keksandra, you are moooost fantastIIIIC," Keksandra imitated, squeaking loudly as Demona hit a sweet spot. "You are an eeeexpeeeert, I must hire youuuu...as a science heeelper laaaady~"
 
The imitation of Demona's voice was actually pretty good, the succubus had to admit. "Yeah! I wanna be in the journa- uh, science books, and stuff!" Demona continued, adjusting her voice slightly. "Let's do another experiment! Where should I put my fingers, dumdum?"
 
Keksandra weakly grabbed the hand groping her breasts and lifted it up to her face. "Ohhhh, put your fingersssssss...in my mouth!!!" she yelled, still maintaining her almost-perfect Demona voice. "I would like you to put the-e-e-em~ in my throaaaaat!"
 
Demona grinned and parted Keksandra's lips, running her index finger over Keksandra's sloppy tongue. "Woo...lad! I wonder what's in your throat! Maybe it's more tenty-cools!" she laughed, adjusting her fingers so that they were all touching. With some force, she pushed as much of her hand as she could deep into Keksandra's throat, the saliva on her tongue covering her hand and wrist.
 
The succubus began to pick up the pace and humped harder, eager to quicken the orgasm and get to the main event of her study. With her hand obstructing Keksandra's mouth, a copious amount of her drool dripped down her chin and onto her chest, some of it running down into the woman's cleavage. Keksandra moved her head back, removing Demona's hand from her mouth and leaving it soaked in her spit.
 
"Whaaaat? Dumdum, I got spitties on my hand!" Demona 'complained', still mimicking Keksandra's voice, which now sounded a lot better.
 
Keksandra tightened up on Demona's cock, the pleasure of being romped so hard getting to her. "Ohhhhh, Keksandraaaaa~ you are so stroooong~" she groaned as Demona's hand pumping her cock faster and faster.
 
Strong could only describe the powerful feeling building up at the base of Demona's cocks. The tentacle-haired demoness humped harder and harder, wondering if she could start an orgasm chain reaction by doing so. Coincidentally and conveniently, Keksandra started to feel a burning pleasure in her own dick.
 
As a result of Demona's movements, Keksandra tightened up incredibly hard and Demona pulled Keksandra in as close as she could, almost crushing both her dicks as she did so.
 
"Demonaaaaaa, I think I'm gonna do it!!!" Keksandra screamed, holding her breath.
 
As she feverishly pounded harder into Keksandra, Demona felt the rising heat travel up both her shafts. Remembering her still-soaking spit-covered hand, she opened her mouth and shoved her hand inside, tasting the thick, lukewarm spit.
 
"Oh, fuck, that's the stuff!" Demona thought, just as she achieved orgasm.
 
Slamming into Keksandra one last time, the succubus unloaded her double payload. Her bottom dick was spraying cum into Keksandra's asshole like a fire hose, filling her up in a matter of seconds and sending the thick brew pumping deeper into her colon. Meanwhile, the release of semen between Keksandra's dress and her skirt and suit wasn't so restricted.
 
Thick, gooey ropes of boiling cum shot out of her top dick over and over. Most of it landed and soaked into the clothes around them, but a decent amount of the cum escaped the fabric and flooded down onto Demona's scrotum and legs.
 
Demona's hypothesis of the "orgasm chain reaction" turned out to be true, as the feeling of Demona's load inside her was enough to send Keksandra over the edge. As she let out an ear-piercing scream, Keksandra's cock exploded with the first, powerful spurt of cum filling the tubing. While the stopwatch automatically switched to the second lap and began recording the length of the orgasm, Keksandra flexed and felt a second torrent of semen shooting out of her dick.
 
The succubus continued to pump the woman's shaft as the waves of cum continued to flood out from both of them. Keksandra's legs shook in ecstasy, the pumps on her feet clicking on the floor repeatedly. Both women were sweating rapidly. Cum began to leak out of Keksandra's asshole, adding to the mess that had already been created.
 
The container continued to record the individual releases of Keksandra's orgasms. As time passed, each release decreased in volume and took more effort for Keksandra to get out of her. She began to struggle on the ninth spurt. Upon letting out her thirteenth and last squirt of cum, the woman started breathing again, gulping mouthfuls of air.
 
Neither of them talked for a full minute until Demona broke the silence.
 
"You were fantastic," Demona commented, huffing and puffing deeply. As she grabbed Keksandra by her underarms and began to lift her off of her bottom dick, Keksandra recapped her feelings.
 
"That...was so AMAZING!" she screamed. "It felt so fugging awesome, your bepis felt so so so SOOOOO good inside my butte and I really wanna do it again and again because you were so amaziIIII-" she paused and twitched as Demona's cock finally pulled out of her ass, followed by a considerable amount of thick, gooey semen, "amazing, and you were pretending to be me and I was pretending to be you and it made my bepis bigger and harder and I wanna keep wearing your outfit!"
 
Demona stood up and stretched out her back, feeling a pop somewhere. "Well, let's maintain this little swap, shall we? I do enjoy these clothes, they're not as restrictive and they're quite comfortable," she agreed, brushing down the dress. She winced a little bit as she felt the familiar feeling of wetness. "We might need to do laundry together after this is over, don't you think?"
 
Keksandra stood up, her now flaccid cock flopping down between her legs, allowing her to finally roll the leather skirt down again.
 
"I think you look pretty!" she said.
 
Demona smiled. "And I think you look very professional," she replied, leaning in and placing her lips on Keksandra's own.
 
The woman closed her eyes and grabbed Demona's cheeks, feeling the pointed tongue of the succubus making its way into her mouth. She mmm'd at the warm taste and wrestled the tongue with her own, eager to win the mini-battle between their mouths. Sadly, the kiss was short, and Demona broke it.
 
"Now, let's get those final measurements," she sultrily cooed, "and the main event can begin."



"12:39pm: Orgasm test complete. Subject's futanari genitalia is fully-functioning and ready for experimentation. Final measurements are as follows: Time to achieve orgasm - 14 minutes and 31 seconds. Length of orgasm - 20 seconds. Volume of orgasm - 31.39mL. Number of individual releases - 13. Will now begin the experiment," Demona spoke into her voice recorder.
 
As she placed her recorder down, she went back to setting up her data acquisition software on her lab computer. All of her data displays were in the form of time versus variable graphs, where the variables would be recorded from Keksandra's body through a number of devices.
 
Demona had all the devices next to her. The first device was the ahegometer, or as Demona liked to call it, the "Mindbreak Meter". Demona had spent a while with Simon, the resident scientist and mathematician of 4chan, trying to perfect this device. After using it for a previous study to determine where exactly the mind "broke", the succubus was able to re-calibrate her invention to define one mindbreak.
 
This special device worked by measuring hypothalamus and nucleus accumbens activity in the brain, as well as recording the amount of oxytocin and dopamine present in orgasm. By taking these factors into account, the ahegometer would then calculate how many "mindbreaks" the subject was going through at the time.
 
The second device was an automatic masturbator. This would fit around Keksandra's cock nicely, and when activated, a pump mechanism within the material would rapidly stroke the shaft. It was pretty much an automatic two-ended onahole, but the material and pump mechanism were elastic enough to stretch to a diameter of three feet without failing.
 
Aside from the ahegometer and automatic masturbator, Demona also had a heart rate monitor, which would measure Keksandra's pulse, as well as a special cock plug, which was vital for the experiment.
 
The succubus finished setting up the software and grabbed the devices, stuffing the cock plug down her cleavage. Plugging the ahegometer jack and heart rate monitor jack into the computer, Demona walked over to Keksandra and kneeled down.
 
"I'm so excited! This is gonna be sooooo so so so fun!" Keksandra squealed. "And I really get to wear your clothes still!"
 
Demona grabbed Keksandra's hand and clipped the heart rate monitor onto one of her fingers. "You sure do, Elastigirl," Demona chuckled, securing the monitor firmly with some duct tape. She connected the two sides of the ahegometer, which both looked like hearing aids, onto Keksandra's ears.
 
After quickly checking that both devices were working by recording a quick test (99bpm and 174 micromindbreaks), Demona crawled between Keksandra's legs and grasped her cock. Feeling it twitch in her hand, Demona pushed one end of the automatic masturbator down onto it until the glans poked through the other side.
 
"Okay, let's see if this thing works..." Demona mumbled, using the wireless remote to activate it.
 
Immediately, the pump mechanism started to stroke Keksandra's cock at a steady pace of 200 up-and-down strokes per minute. Keksandra groaned in delight and sighed heavily.
 
The succubus turned off the device and smiled. "I think two hundred is a good rate to maintain," she thought.
 
She waltzed back to the lab computer and began recording all rates again, this time not stopping until the experiment was done. Demona turned around and cleared her throat.
 
"Now, Keksandra, I will begin the experiment. The masturbator will help you reach orgasm, but the moment you feel it coming, I want you to inform me. This part is crucial for the study," Demona instructed Keksandra, who nodded eagerly. Smiling seductively, Demona clicked the remote in her hand, activating the masturbator again.
 
The pump started up once more, stroking Keksandra's dick at the same rate Demona had decided on. The succubus knelt down and watched Keksandra's face contort as the wonderful feeling returned. Taking a quick glance at the lab computer, the early signs were showing on the software. The ahegometer was recording 3.553 millimindbreaks and her heart rate had risen to 108bpm. She looked at the monitor attached to Keksandra's finger.
 
"Oh, damn, almost forgot," Demona thought.
 
Quickly getting up and searching through one of her drawers, the succubus pulled out a length of rope. She returned to Keksandra and got down on her knees, grabbing the woman's arms and forcing her to keep them behind her back.
 
"Whaaaaatcha doing~" Keksandra moaned.
 
"Gotta make sure your hands don't go catching onto things," Demona explained, tying the rope around the woman's wrists and hands. "I need a continuous recording of everything."
 
"Okaaaay, Demona-Lisaaaaa..."
 
With that out of the way, Demona resumed her place next to Keksandra and waited, making sure the cock plug was still present between her breasts. To pass the time, she observed Keksandra, enjoying her cute little moans and squeals.
 
She hadn't really interacted with her that much in the past. The first time Demona ever made contact with her, it was when she was busy marking every adult board-tan's territory. Obviously, very few enjoyed it, especially the /u/ twins, who loathed dicks with a passion. There were the few out there who enjoyed Demona's forceful nature, such as long-time friend Emily, who was no stranger to having a horse cock filling her every hole, and /x/, who Demona had helped deal with her break-up with Teej.
 
Keksandra might not have been that important to life in Demona, but the succubus soon discovered just how special she was. She learned of Keksandra's special elasticity, which enabled her to be pushed to unspeakable limits. She learned of her inability to feel pain and her practical immortality, which meant that Demona could put her through anything extreme without giving her a scratch.
 
Most of all, she learned that Keksandra's sex drive was astonishingly high, so much that she'd even worn Demona out that one time she tentacle-fucked her every orifice for nearly two days straight. By the time Demona had collapsed on her bed with no energy left, Keksandra was still on her feet and somehow had MORE energy after getting tentacle-fucked, complaining that she wanted to keep going for a while. The moment Keksandra climbed onto her bed and tried to suck Demona's flaccid cocks in order to get them hard again, all while semen was still spurting out of her asshole, Demona knew that she was going to be very important for her studies someday.
 
Demona reminisced about all the times she'd put Keksandra through almost every fetish in the book, jiggling Keksandra's breasts in her hands as she did so. Even her ironic silly attitude and meme references had grown on her as time passed, and now Demona found it to be charming and enjoyable. The succubus wasn't even shy about making a few meme jokes herself, like that one time she said "Nice dubs, checked!" as she came all over Keksandra's double-D sized breasts.
 
"Demonaaaaa~"
 
There was that sweet, high-pitched voice. She loved how high it would get whenever she screamed during orgasm, and she especially loved it when she let out those high-pitched moans and gasps when...
 
"Demona, I'm about to cuuuuum~"
 
Snapping back to reality, Demona shook her head.
 
"Oh, uh, yeah, right!" she stammered, quickly crawling between Keksandra's legs. She fished out the dildo plug from within her cleavage and prepared to do what had to be done.
 
Keksandra jolted hard and shook her legs, causing the high heels to click on the floor again. "Oh, FUG! It's gonna be YUGE, for real! It's comiiiiing! I'm-" she yelled, closing her eyes and bracing for another orgasm.
 
*SQLORP!*
 
Squealing loudly, Keksandra felt something getting jammed into the tip of her dick. Opening her eyes, she saw something green forced down her urethra, which created a bumpy five-inch bulge down her shaft. Demona pushed her hand on the flat end of the thing, forcing it down until only the base stuck out of her cock.
 
"Ohhhhuuuuhhhh, Demonaaaaa! What is thaaaaat!?" Keksandra groaned, the feeling of orgasm intensifying.
 
Demona giggled, fondling Keksandra's balls gently. "That's the crucial part of this study, sweetie. It's a cock plug," she explained, feeling the spherical organs trembling in her hand. Keksandra shivered, feeling the familiar pleasure of hot cum boiling within her shaft.
 
"What's a c-cock pluuuUUUUUuuug~?" Keksandra squealed. The pleasure was growing exponentially, fueled by the still-pumping masturbator on her cock. She really, REALLY wanted to cum, but the plug was sealing it in completely.
 
"This little thing makes sure your orgasm won't end for a while," Demona continued, tapping the plug's base. "It keeps all that semen inside your cock so that you won't be able to ejaculate. You're going to have a long, long orgasm, Keksandra!"
 
Keksandra was already having difficulty comprehending Demona's words, since the pleasure was intensifying more and more. Her orgasm had been going for a full thirty-five seconds, but not a single drop of semen had come out.
 
"Nnnngggghh-uh...it...feels...so...hot!" Keksandra screamed, her tongue flopping out of her mouth. She began to breathe erratically, drool leaking down her chin.
 
Demona continued to jiggle Keksandra's balls, feeling them swell up in her hands. As the orgasm continued, the masturbator was still working Keksandra's cock fast. As a result, the stimulation caused the woman's testicles to continue rapidly producing semen. and with the tip of the cock plugged up, the excess seed began to inflate the testicles dangerously fast. By the time a minute had passed, they were each already the size of baseballs.
 
"Fuuuug...my...balls...GROWIIIIING!!! So...fuuuuuuuuug~"
 
The succubus let the hairless sac go and checked her lab computer, checking the data being recorded. Ninety seconds in, Keksandra's heart rate had increased to 144bpm. Demona looked at the ahegometer graph and saw the mindbreak level rising rapidly. It had already jumped up to 819 millimindbreaks, and was practically seconds away from passing the one mindbreak mark.
 
Demona sat in her chair and sighed contentedly, watching gleefully as Keksandra's face twisted and contorted as waves of unfathomable pleasure swept through her body. She could still see her testicles growing, and by the time Keksandra's ahegometer recorded one mindbreak, they were the size of soccer balls.
 
"D-D-D-Deeeeemooooonaaaaaa~" Keksandra stammered.
 
"Yes, Keksandra?" the succubus asked, dangling one of Keksandra's flats from her toes.
 
"Hooow...long...this...go...foooooooor~"
 
Tapping her chin, the succubus recalled a study from one of her fetishology textbooks. "Keksandra, do you know what the longest orgasm is?" she asked.
 
"Nooooo~"
 
"In 2004, a futanari subject was tested in an experiment like this," Demona recalled. "She was able to withstand an orgasm for five minutes and sixteen seconds."
 
Keksandra could hardly see, given that her eyes had rolled up into her head and tears of joy flooded her vision. Still, she could speak in short, drawn-out words. "Soooo...I...breeeaaak...recoooord~" she moaned.
 
Demona nodded. "Of course. In fact, it's already been seven minutes," she said, checking the ahegometer graph, "and you're up to 1.283 mindbreaks. The highest I have ever recorded was 1.321, so you'll break that soon."
 
"Soooo...how...loooooong~"
 
"Oh, since you're a special subject, I'd say, ohhhh, about twenty-four hours," Demona continued.
 
Keksandra lowered herself until she was resting on her back. "Fuuuuug...yeaaaaah...feels...ebiiiin~" she gasped.
 
Demona got up from her chair and rested on her stomach, facing Keksandra's inflated testicles. The large masses were still growing dangerously fast, having now grown to the size of beachballs. The massive organs stretched out the scrotum, revealing the impressions of the veins protruding from the testicles.
 
The succubus placed an early to one of the balls and listened carefully. She could hear little signs of activity, such as the sloshing of thick, gooey seed and the minor contractions of her testicle. A little grumble resonated inside the space, perhaps a sign that semen was going to be secreted a lot faster.
 
It was going to be a long time before the experiment could conclude. Demona made a mental note to organize a babysitter for Deelette, in case Colette was too busy. Sighing happily, Demona grabbed one of Keksandra's inflated testicles and rested her head on it, allowing the woman's cute moans and the rhythm of the masturbator pump to soothe her.



Lasting twenty-four hours in the laboratory for one study was taking its toll on Demona, but she found ways to cope with her boredom.
 
Five hours and thirty-eight minutes after the succubus had jammed the cock plug deep into Keksandra's futanari urethra, the woman felt like she was about to ascend another plane of existence. The masturbator on her cock continued to pump her shaft rapidly, which was dying to let loose the monumental torrent of boiling hot cum contained within it. Any normal being would have passed out after having an orgasm denied for minutes, but not Keksandra. Even though the extreme sensitivity and demand to release increased tenfold every half hour, she remained strong and handled it like a professional.
 
Demona could only describe the woman's face "as if every ahegao expression in existence was added together and raised to the power of ten." Her pupils had been reduced to pinpricks, she was sweating like crazy, her eyes had almost rolled back into her head, and tears of joy leaked down her face non-stop. Her top teeth were always either clamped down onto her bottom teeth or biting into her lip (which, due to her physiology, remained unharmed). Despite the amount of punishment that Keksandra was going through, somehow she was able to breathe properly, although talking was reduced to one labored word at a time.
 
The succubus checked her computer to get an update on the results. Keksandra's heart rate was maintaining a steady but rather high 153bpm, but the ahegometer's recordings continued to astonish Demona. Keksandra was experiencing a measurement of four mindbreaks. Not one subject had gone beyond one and a half at any stage.
 
"You are truly a remarkable person," Demona commented, walking to a nearby bookshelf and running her finger along the spines of the books. "I've got a few texts here that I can read aloud. It might help pass the time. Do you fancy anything in particular?"
 
Keksandra managed to eke out a few words. "Nooooot...reallyyyy...can...youuuuuu...taaaaalk...about...yourseeeeelf?" she squealed, one word at a time.
 
Demona smiled, looking back at Keksandra. "Well, that's quite thoughtful," she replied, eyeing Keksandra's absolutely gargantuan balls. A little idea formed in her head. "Let me grab a seat, first."
 
Brushing down the woman's purple dress that she still wore, the succubus moved between Keksandra's legs and faced her stretched, massive scrotum. The secretion of semen from the masturbator's stimulation had not abated, and Keksandra's testicles continued their unholy growth as the hours passed. By now, they had bloated out to such a large size that it was impossible to notice that they were growing. After just five and a half hours, both of her testes had grown to the size of small beanbag chairs.
 
Demona pressed a hand into one of the huge spheres and pushed. Though they were filled to the brim with Keksandra's gooey seed, there was still a good amount of give. Satisfied, the succubus turned around and placed both hands on the firm surface behind her. With a little bound off of her toes, she jumped back and planted her bottom square on Keksandra's right testicle, feeling it sink a few inches into the flesh.
 
"Hnnnggghhh...ohhhhh~"
 
Swinging her legs around, Demona placed her feet firmly on the other testicle and carefully slid down between the two. As her bottom descended down the gap, she lifted her feet up until she stopped descending. Demona let her legs curve along the surface of the left testicle, leaving the succubus resting nicely between both of Keksandra's balls.
 
"Ah, these are quite comfortable," Demona sighed, cheekily rubbing the soles of her shoes on the other testicle.
 
"Fuuuuuggg...dress...shoes...feels...gooooood...on...benis..." Keksandra groaned.
 
Demona ignored her and decided to find out what Keksandra wanted to know. "So, what would you like to know about me? Anything of interest?" she asked.
 
"Yooouuuurrr...daaaaays...and...stuuuuff..."
 
The succubus smiled. "Ah, just my life in general? Well, I've been quite busy," Demona elaborated. "Outside of my work, I'm helping Deelette out with her schooling. A few days ago, she invited Kikani over and I swear she must have taught Deelette how to be a bit more cheeky..."
 
"Kikaaaaani?"
 
"Hmm? Oh, Kikani's one of Deelette's friends, she attends the same school as her. You know, the school for monster children a few blocks away from here?"
 
"Ohhhhh...yeaaaaah..."
 
"Yes, well, Deelette's been trying to prank me, but she's not very discreet at it. Fact is, all her pranks are good-hearted, because she wants to make sure I'm not hurt or angry. Anyway, I'll call Colette later and let her know that I won't be home tonight, since I'll be here with you. If something comes up for Colette and she can't be around to take care of Deelette, I'll see if I can organize for her to sleep over at one of her friend's places."
 
"Liiiike...Kikaaaaaani?"
 
"Sadly, no. Kikani caught a virus yesterday and she's bedridden. She'll have to stay in bed for a week or two until it goes away. Lucky her, no school for that long and she gets to watch TV in bed all day!"



Staying overnight at the university wasn't uncommon for Demona. Sometimes, her studies required an overnight stay in her lab, and she was prepared to deal with such an occurrence. Still, it did get kind of lonely.
 
It was half past five in the early morning, and Keksandra had been under a constant denied orgasm for sixteen hours and thirty-nine minutes. Demona had already taken a few pep pills to keep her up, but sleep continued to chase after her. Keksandra, of course, was virtually unable to sleep, given that she was experiencing 9.112 mindbreaks and her testicles were now about as big as extra large beanbag chairs.
 
Demona, who sat comfortably on one of Keksandra's monstrous testes, decided that she needed more than a prescribed boost to help wake her up. Bounding off of her seat, she landed on her feet and stretched out.
 
"Keksandra, I'll be gone for a bit, I'm going to get a coffee from the cafeteria," Demona said. She swept a hand down the front of Keksandra's dress and tugged it forward, checking to see if the semen stain from before could be removed. She used one of her moistened tentacles to rub at it, getting as much of the flaky white stain out as possible. "That should be enough," she thought.
 
The succubus departed the laboratory after placing a Do Not Enter notice on the door and locking it. She strolled down the empty hallway, the light clapping of Keksandra's flats on the polished floor breaking the deafening silence coming from inside the building. It was a chilly morning, chilly enough that Demona wished she'd temporarily taken her suit back to cover up her arms.
 
A quick elevator descent later, Demona was leaving the Futology Hallway West building and making her way down to the cafeteria, which was a few hundred yards away. As usual, the lights were on inside the cafeteria, indicating that the early shift workers were up and about.
 
She made her way into the cafeteria and stood in front of the counter. Instantly, a worker came out to greet her. "Professor Demona, doing an all-nighter?" he asked.
 
"You know me well," Demona chuckled, hearing footsteps behind her. "A large espresso, please."
 
"That'll be four ninety."
 
Demona instinctively reached for her suit pocket to grab her purse...only to get a handful of dress rather than a handful of leather. She facepalmed mentally.
 
"Ah, shit, my purse is back at the lab," she groaned. She did not want to walk all the way back in the chilly night air just to get-
 
"Espresso for me, too. I'll pay for Demona's," a familiar voice called out.
 
Demona turned around to the source of the voice. There was another woman behind her, wearing a grey hoodie with a white shirt, a pair of blue jeans, and a fedora on her head. She didn't need to see the obviously fake plastic horn and dyed purple hair to know who it was.
 
"Emily?" she exclaimed.
 
The pony lover gave her a thumbs up and smiled. "That's my name, don't wear it out," she cheekily replied, slapping a ten dollar note on the counter. "Keep the change, bro."
 
The worker took the note and thanked Emily, telling the two to grab a seat while their drinks were prepared. The two women picked the nearest table and sat down.
 
"How'd you know I was here?" Demona asked, incredulous at how Emily knew she would be at the university right now.
 
Emily laughed. "Funny story. My brother was marathoning that Rick and Morty show and he told me, hey, I found a show with a more cancerous fanbase than yours," she explained. "So, he was nice enough to invite me over. I asked him how Colette was doing and all, and he told me she was taking care of, and I quote, "little Deelette", so I asked him what the hell you were doing and he told me that you were here for the night. Anyway, he dropped off after that Pickle Rick episode I heard so much about, so I fucked off and came to find ya."
 
Demona smiled, enjoying the little story Emily had for her. "So, how'd you know I'd be in the cafeteria?" she asked.
 
"Actually, I expected you to be in your lab. I was going to go there, but then I saw you, so I followed ya," Emily explained further. She signaled with her hand, pointing out the fact that Demona wasn't wearing her usual clothes. "So, uh, what's with the get-up? How come you're wearing Keksandra's dress and all that?"
 
The succubus chuckled just as the cafeteria worker came to their table, carrying their espresso cups. The two thanked them for their drinks and continued their conversation.
 
"It's quite a bit of a story, you want to hear about it?" Demona asked.
 
Emily nodded eagerly, sipping her espresso.
 
"Well, I'm doing another paper and I'm using Keksandra as my test subject. She's actually in my lab right now, I can totally take you there so I can show you what I'm doing," Demona explained.
 
The pony-lover raised an eyebrow. "Mmm, I'd love to see that...still doesn't explain the whole get-up you've got, though," Emily replied.
 
"Oh, we swapped outfits. It's kind of her fetish, actually."
 
"Is that required in your study?"
 
"Not really, but she wanted to do it anyway to make it even better for her."
 
As Demona took a big gulp of her steaming hot espresso, Emily laughed. "Oh man, I have GOT to see what you're doing with her," Emily replied. "Does she look good in whatever you were wearing?"
 
"You bet. Looks like a professional, looks great in leather and heels."
 
The two continued to chat for a few minutes as they quickly polished off their espressos. Demona found herself full of energy and ready to finish recording the data from her study, while Emily was hyped up on caffeine and ready to see what Keksandra was being put through.
 
"C'mon, take me, take me, take me!" Emily demanded, feeling jittery.
 
Demona raised an eyebrow. "Emily, easy on the caffeine..."
 

 
"Ho. Lee. Shit."
 
Emily's words pretty much summed up her reaction as she saw Keksandra. After seeing her lying on the floor, dressed in Demona's clothes, with her arms bound behind her back, a cock plug blocking her constantly-stimulated urethra and both her testicles absolutely massive, it seemed appropriate that "holy shit" was the first words to exit her mouth.
 
"Ain't she amazing?" Demona commented. "I've had her here for seventeen hours, and she's been having an orgasm for that long. All the cum she's going to release? It's all in these babies." She emphasized 'babies' by jiggling one of the engorged testicles in her arms.
 
Emily glanced at the computer, noticing the graphs on the monitor and the wires connecting the computer to Keksandra. "What's with the wires?" she asked.
 
"I'm measuring heart rate and her mind break levels," Demona replied.
 
"Mind break whats?"
 
"Mind break levels. It measures the activity in the brain during sexual pleasure and orgasm. The moment somebody suffers a mind break, they record a level of one mindbreak, or a thousand millimindbreaks," Demona explained. "And Keksandra here? She's experiencing a level of 9.142 mindbreaks at once, and she's not even unconscious."
 
Emily could only mouth the words "holy shit" again.
 
"Hiiiii...Emilyyyyyyy..." Keksandra croaked out.
 
The pony-lover waved slowly. "How ya holding up there, Kekky?" she asked.
 
"Feels...simplyyyyyy...ebiiiiin..."
 
Emily looked back at Demona, ready to say something else. Before she could, she couldn't help but notice how tight Keksandra's dress was on the succubus's breasts. She could see her hard nipples poking into the fabric. Under the breasts, the familiar bulge of her double cock lifted the dress forward slightly.
 
It had been a while since Demona had banged Emily. Last time she did, it was just before the previous year's Winter Ball. Since then, she hadn't experienced a romp with the succubus, a feeling that she missed. Though her horsecock dildos were satisfactory, it wasn't enough.
 
"Demona?" Emily asked.
 
"Hmm?"
 
"For the love of Celestia, do me. Fucking. Do me," Emily pleaded.
 
Demona raised an eyebrow. "Oh, has somebody been pining for the D's?" the succubus asked, feeling her cocks growing underneath the dress.
 
"Do me right here in the lab. I want to be dominated by Keksandra. Fuck me. Fuck me with those dubs."
 
The succubus hnnnngh'd quietly, grabbing her bulges through her dress. It had been so long, but truth be told, she did miss the times she banged the pony-lover into the ground. And what better way than to break the drought now: by roleplaying as her test subject, who had swapped clothes with her, and banging a different girl in the workplace.
 
Demona worked out her falsetto voice once more, remembering back to how she was testing Keksandra's cock. "Okay, dumdum! Pull your pants down so you can check my dubs!" she imitated.
 
Emily felt like she was going to cum on the spot.



Well, the espresso definitely gave Demona the caffeinated kick she needed to get through this study. That, and the fact that she'd double dick-fucked Emily's plump ass for an hour while Demona was impersonating Keksandra the entire time. Normally, Demona would have cleaned up the puddle of her cum and Emily's fragrance off of the floor, but given what would be happening pretty soon, she decided to leave it.
 
The succubus stared at her lab computer, eagerly counting down the final seconds of her recordings. Twenty-four hours had passed since the software had  begun recording Keksandra's mindbreak and heart rate levels. The woman was still on the floor, looking like the star of the greatest hentai of all time. The cock plug was still firmly planted down her urethra, holding in the lake of cum that would soon be released.
 
"Five, four, three, two, one...done!" Demona cheered, fist-pumping the air as she stopped the software just as it reached a full day of recording. "God damn, you are fucking amazing, Keksandra!"
 
The woman's ahegometer reading had long-since shattered the mindbreak record, and the final recording officially declared that she was experiencing an incredible 11.396 mindbreaks. Even Demona, who knew of Keksandra's inhuman abilities, couldn't believe she was withstanding it.
 
"Dooooooone...?" Keksandra moaned.
 
"All done, indeed," Demona sighed contentedly, working at her computer. She decided to make certain of it that her efforts didn't go to waste. After saving the recordings locally, Demona proceeded to upload them to the university's cloud system as well as to her personal Google storage.
 
To make super certain that she had the recordings, the succubus pulled out a few USB sticks from her drawer and copied the files onto each of them, ensuring that her work wasn't lost.
 
Demona stood up and stretched her legs, feeling her joints pop slightly. "Keksandra, I have to say, your contribution to this study is going to be invaluable for my next paper," Demona complimented. "This could open up a few doors in not only fetishology and futology, but perhaps even neurophysiology."
 
"Neeeeuuuro fizza wuuuuzza~"
 
Smiling wickedly, Demona remembered exactly what was coming next. "Now, let's get you unplugged, shall we?" she cooed sultrily.
 
"Yaaaaaas~"
 
"But first, I think I'll make sure nothing gets damaged."
 
The succubus moved to her desk and shut down the lab computer, before following the cables and locating the power socket. After turning off the power, she unplugged the computer and tidied up the loose cables so that nothing was trailing. With her strong hands, Demona picked up the computer and cables.
 
"Now, where to store it..." she mused, looking around for a safe place to keep the device. She mentally slapped herself as she saw a door at the opposite side of the room. "Ah, yes, storage."
 
After placing the computer high up on the shelves in the storage room, Demona grabbed a few pieces of hard plastic and a roll of duct tape. For the next fifteen minutes, she looked for every power socket in the room and duct taped plastic over the exposed inputs.
 
"That'll make sure I don't fuck up the power anywhere," Demona thought. A devious smile spread across her face as she eyed her subject, whose balls were now bloated to the size of...well, she couldn't think of anything to compare their size to, they were just ginormous and WAY bigger than the largest beanbag chairs now. "Showtime."
 
Strolling over to Keksandra, she lifted her up and rested her head on her breasts. Curling her legs around the woman's waist, Demona reached up and gave Keksandra's breast a few gentle squeezes. She swore that she could hear faint "honk" noises coming from there.
 
She was proud of her for helping with her study, and the study was going to be Keksandra's reward.
 
"Demonaaaaaaaaa..."
 
"Mm-hm?"
 
"I...cuuuuuum...noooow?"
 
Demona grinned and moved closer to her ear, giving it a gentle lick with her tongue. "You're going to cum lots, aren't you?" she whispered, feeling Keksandra shiver as her breath tickled her. The woman nodded, just barely, letting her know that she was aching to release.
 
The succubus leaned forward and grasped the cock plug just underneath the exposed base. Giving it a firm tug, she saw it slide up just a little bit. She drew from her inner Bob Ross and whispered into Keksandra's ear again.
 
"Let's start off with a lot of titanium hw-ite."
 
With a strong, sharp tug of the cock plug, it popped out of Keksandra's urethra with a resounding *schlup*.
 
And then, at that very instant, Kekatoa erupted.
 
Demona felt the cock plug being thrown out of her hand as the most powerful, gooey, boiling jet of semen sprayed full force out of Keksandra's cock. It wasn't just a cumshot, it wasn't even a cumblast, it was a cumSPLOSION. With an entire day's orgasm in the making, Keksandra released what /b/ would have described as "the cumshot that changed the world" in an unmitigated, unrestrained, direct torrent that splashed all over the ceiling a full thirty feet away from her.
 
As the sound of the thick liquid's escape filled the room, Demona could actually feel herself being pushed back. Keksandra's cumshot was so powerful that it was generating enough force to push two fully-grown adults along the floor. As Demona glanced at Keksandra's massive testicles, she wanted to scream in delight. Even though Keksandra was cumming at possibly gallons per second, the balls weren't getting ANY SMALLER.
 
"DEMOOOOONAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!" Keksandra screamed fiercely, her tongue lashing all over the place, tears streaming endlessly down her cheeks.
 
Demona assumed control and grabbed Keksandra's cock in both her hands, feeling the cum travelling within the shaft. She moved the massive erection to the left and right, redirecting Keksandra's non-stop ejaculation and painting every wall with her seed. She felt her back pressing up against the wall behind her as the force from the cumshot had pushed her as far back as they could go.
 
Her grin intensifying, Demona aimed the cock straight upwards and began blasting the ceiling above them with Keksandra's never-ending orgasm. Thick, white streams of cum rained down upon the pair, coating almost every inch of their bodies with seed. Demona felt the semen soaking deep into Keksandra's dress, causing it to cling tightly to her skin, but she didn't care. This was a once in a lifetime moment, and she was going to savor it.
 
A growing puddle of cum formed at their backsides and feet. Demona paused to wipe the cum out of her eyes and took control again, aiming jizz at every corner of the lab. Windows, doors, the floor, benches, it didn't matter. She wanted to turn her lab into a masterpiece.
 
Minutes passed, and Keksandra's orgasm hadn't subsided one bit. The woman kept screaming and spasming wildly, and her balls had shrunk the TINIEST bit. Puddles of cum formed all over the lab, some joining together to form even bigger puddles. Demona couldn't believe just how much semen was in those balls.
 
As time continued to pass, Demona and Keksandra enjoyed the latter's wildest frenzied cumshot. Most of the time was spent coating the lab in ungodly amounts of boiling hot cum. Occasionally, Demona would shower the two in the delightful liquid and swallow a few mouthfuls. As the succubus noticed Keksandra's balls shrinking at an increasing rate after twenty-five minutes, she decided to milk the last moments.
 
The laboratory floor was now almost shin-deep in semen as Demona stood up, feeling the sticky fluids leaking into Keksandra's flats, which oddly made Demona more erect than ever. Splashing through the liquid spunk, the succubus managed to stand in front of the cum torrent and enjoyed the full blast of semen to her face, chest and stomach. Remembering that one scene of Homer Simpson drinking ranch dressing from a hose, she opened her mouth and filled her mouth with the salty goo, savoring its taste.
 
Finally, after half an hour, Keksandra's orgasm was finally slowing down. Her balls were quickly shrinking down to normal size, and her cumshot was coming out in individual squirts, though they were still relatively big. Demona crawled through the white, sticky liquid and placed the tip of Keksandra's flared head in her mouth, swallowing the rest of the semen as it flowed out.
 
As the last drop of cum sunk down Demona's throat, Keksandra fell on her back, splashing in the semen pool. Because of the depth, her face disappeared underneath the white liquid. Demona crawled forward and lifted her head up out of the semen, watching the sticky fluid cling to her face.
 
"D-Demona..." Keksandra exhaled, taking deep breaths.
 
"What is it, Keksandra?" Demona asked.
 
"That was the best study ever. It was nice study, and I felt nice, and it was simply ebin."
 
The succubus chuckled and licked her cheek, swallowing the gooey liquid that her tongue collected. "I am glad you took part in it. You are remarkable, and you have helped me out so much," Demona said, giving her a deep kiss on the lips.
 
Keksandra looked around and looked all over herself. It was all cum. Cum everywhere. Her cum. Cum that soaked into Demona's clothes and clung to her body. Cum that was dripping off the ceiling and down the walls.
 
"Aren't you gonna get in trouble for this? A-and what about our clothes?" she asked.
 
Demona smiled. "This is 4chan University, Keksandra. I could accidentally blow up half the building and my job would still be safe," she explained, giving her another kiss. "And wouldn't you like to walk home together, wearing each other's cum-soaked clothes?"
 
Keksandra giggled and, to her amazement, her cock was somehow getting hard again.
 
"I'd like that, dumdum."



The janitors at 4chan University were used to the mishaps that occurred in the futology and fetishology departments, be it a dried cum stain or discarded, broken sex toys being left behind in the labs.
 
So, when one janitor walking down the hallway noticed a growing puddle of semen leaking out underneath the door, she knew this was going to be a hell of a job. And of course, it just happened to be Professor Demona's lab.
 
Seconds later, the door flew open, and a torrential flood of cum began to fill the hallway. The janitor just stood there and allowed the puddle to stain the bottoms of her boots.
 
Demona and Keksandra stumbled out of the laboratory in each other's arms, both soaked to the bone in sticky semen. The janitor noticed that the two were in each's others clothes and raised an eyebrow. "Professor," she deadpanned, catching the succubus's attention.
 
Standing up straight, Demona flexed her back and walked to the janitor, kicking up some semen with her feet. "You, er, might want to call backup on this, Rose," she suggested, giving the stoic janitor a tap on the nose. "Perhaps the entire team and a few volunteers, too."
 
Demona signaled to Keksandra with her finger and gave her a wry smile. "Come along now, Keksandra. Deelette won't be home from school in a few hours," she called out. Keksandra giggled sheepishly under her breath and stumbled her way through the enormous cum puddle, treading cautiously in the succubus's high heels. As she passed the janitor, she gave her a friendly wave and giggled again.
 
The janitor maintained her expressionless face and sighed. "Fuckbuddies," she mumbled, making her way through the puddle and to the entrance of the laboratory. Only then did her face change, even just a little bit, to a look of amazement.
 
The entire laboratory was, down to the last square inch, covered in semen. Dripping down the walls and the ceiling, collecting in a shin-deep puddle that was still flooding out into the hall. Large ropes of it connected lab benches, hung off of tables and, well, just turned everything into a sea of white.
 
What did get a little approval out of the janitor was that she noticed the initiative of Demona, having stored away her computer and covered the power sockets. Still, this was going to be a lot of work.
 
Sighing, the janitor took out her walkie-talkie and turned it on, remembering the words Demona had given to her. "Team, head to room 319 of Futology Hallway West. Bring everything," she spoke, pausing to consider her next words, "and Janice, contact the Dean."
 
 
 
The Dean decided that Demona's laboratory had to undergo an extreme clean for the next two weeks due to the incredible volume of cum that had ended up in there. Of course, the Dean wasn't annoyed with Demona, he was quite impressed with her. Upon hearing of the succubus's new study, he was thrilled to hear the concept.
 
"That subject of yours sure is something," the Dean laughed.
 
Feeling that Demona deserved a nice break, the Dean allowed Demona to stay home for the following fortnight, with pay. Before she did, the succubus decided to take care of one last piece of business: Getting rid of Keksandra's dick with futa-B-gonine. The woman was saddened to see it go, but Demona surprised her by admitting that she had secured a sufficient quantity of demonafutine and futa-B-gonine for the future (and that half of it was being kept in her bedroom).
 
Demona's new paper, "In Denial: Utilizing a Practical Case Study to Test the Limits of Futanari Orgasm Denial", proved to be an instant success. Following a week-long session consisting of rigorous data analysis of her recordings, in-depth research of other journal articles, and a clean, formatted write-up with referenced to over one hundred other articles, Demona had produced a fantastic new insight on orgasm denial during her break.
 
The review committee of the International Journal of Fetishology and Futology was unanimously in approval of the paper, which was quickly published in October 2017's edition of the journal. Although Keksandra wanted to be named as Demona's subject in the article, she was disappointed to learn that the committee decided against it. Demona did, however, reach an agreement with the committee in which, while the subject would still remain anonymous, Keksandra would be credited as Demona's partner in the study.
 
Keksandra was happy that her name was out there, and she got to be interviewed with Demona a few times in relation to the article.
 
Later in the month, Demona came forward with an offer for Keksandra: The succubus would pay for her to attend the university and work her way towards a PhD in memetic communications. Demona even said that if Keksandra wanted to quit the course if the work was too much for her, she would be glad to let her drop out.
 
Gleefully, Keksandra accepted and was enrolled into the next academic year. Initially, Demona stressed that the introduction of serious work was going to overwhelm her, but within weeks, Keksandra displayed her incredible talent. She was mastering her memetic communications course like a boss.
 
The university enjoyed having Keksandra attend, and she was blessed with the right to continue being a subject in Demona's studies (to be honest, she didn't need permission), though she would always be credited as a partner and not the subject.
 
Over the succeeding weeks of the succubus's study, Demona and Keksandra bonded together. They agreed that they would become closer friends outside of university, and soon, Keksandra was frequently over at Demona's residence. Deelette enjoyed Keksandra's presence because of her bright humor and goofy attitude, and even took to calling her Aunty Kekky. Even Colette liked having Keksandra around, since she did enjoy the memes that came out of cartoons.
 
 
 
Demona put pen to paper and began to scribble down another fantastic idea.
 
"Tentacles & Testicles: Analyzing the Reproduction Rates of Tentaculum Colescreoi Birth via Testicular Confines
October 13, 2017, 10:29pm: Idea gained after brainstorming. Plan of attack - Keksandra, of course. Also, secure mature tentaculum colescreoi eggs for urethral insertion, as well as the automatic masturbator."
 
The succubus put her pen down and got up. Walking downstairs, she found Keksandra still sitting on her couch, watching cartoons as a tuckered-out Deelette snuggled sleepily into her lap.
 
"I'll put her to bed, she's got school tomorrow," Demona said. "You go wait up in my bedroom."
 
Keksandra gave Deelette's tentacle hair a quick tussle before the young girl lazily stood up, rubbing her eyes.
 
"Goodnight, Aunty Kekky," she murmured.
 
"Night-night, Deelette!" Keksandra called out, waving gleefully as Deelette made her way up the stairs with Demona. Keksandra turned off the television and walked upstairs as well, turning the opposite direction of the two succubi and making her way to Demona's bedroom.
 
She noticed Demona's notepad illuminated under the table lamp and peered at it.
 
"Oooooh," she cooed, liking the idea of having tentacles inside her. "Tentacles in benis, ebin!"
 
Closing the bedroom door, Keksandra began to undress herself, tossing off her hat, wiggling out of her dress and kicking off her flats. As she tossed her panties off, Demona entered the room, her perky nipples peeking through her t-shirt.
 
"I assume you've seen the notepad?" Demona asked, smiling. Keksandra nodded eagerly, her breasts jiggling ever-so-slightly as she did.
 
Demona began to undress herself, stripping the t-shirt off of her chest and freeing her large boobs. "Well, assuming all goes well, we can began that one next week," she estimated, unzipping her high-heeled boots and beginning to peel off her leather leggings. "Did you do your homework and give it to Professor Bateman?"
 
"I finished it yesterday and handed it in, dumdum!" Keksandra giggled, blushing as she watched Demona removing the leggings. "Aww, those look comfy."
 
The succubus smiled. "You don't have to ask if you can wear them," Demona reminded her. "Remember, mi ropa es tu ropa."
 
Keksandra cocked her head. "Huh?" she asked.
 
"It means 'my clothes are your clothes', dumdum," replied the succubus, imitating Keksandra's falsetto voice on the last word. "Well, I substituted 'house' for 'clothes', so I'm assuming that's the right phrase still. Anyway, if you like what you find in my room, you can try them on."
 
As Demona removed her panties and tossed them on the floor, Keksandra giggled heartily. "Well, since tomorrow's Saturday, that means I've got a whole day to try on your dresses and shoes and everything!" she cheered, flopping on the bed. "I'll pretend to be a fashion model for Deelette and she'll tell me if she likes it! Maybe I'll wear lots of dresses and lots of leggings at the same time! And I wanna try on those boots, they look cool!"
 
Demona crawled under the covers and propped her head up with her shoulder. Keksandra looked at her face and blushed again, diving under the covers and getting close to the succubus.
 
"One in each hole, or two in one hole?" Demona asked, reaching under the covers to give one of her cocks a rub.
 
Keksandra thought for a moment. "One in each! Check my dubs with your big bepises!" she decided, turning her back to Demona and waiting.
 
Demona shuffled forward and reached around Keksandra's waist, pulling her in closer. The woman giggled, feeling Demona's dicks rubbing up on her back. The succubus shuffled a bit more until both cocks were lined up with Keksandra's cunt and asshole.
 
"You're going to be filled with lots of my cum, won't you?" Demona whispered sexily, licking the nape of Keksandra's neck and burying her nose into her soft hair. "And you'll lick it up if it gets everywhere, won't you?"
 
Keksandra smiled. "Yes, Demona," she cooed.
 
"Good girl. Now check 'em."
