The word insatiable seemed an appropriate word to describe the young woman of twenty-two, Jessica Marshal. She had wanted to screw her darling older sister since she first discovered what the over sized appendage betwixt her legs was made for, though she knew her more modest sibling would never go for the taboo nature of such a relationship, at least not without a little help. Jessica finally found the leverage she needed to convince Serenity otherwise. She happened to stumble upon a series of extremely raunchy pictures on her sister's cellphone and made sure to send them to her own phone as well. It had only been a couple of hours since she had confronted her sister with the lewd proposition. They were going to screw, but not just that, Jessica was going to tape the whole thing. The entire living room had been transformed into a make-shift studio. A large white sheet was draped over the couch which would serve as the center stage, with half a dozen cameras arranged in a semi-circle, sure to capture every debauched angle. Jessica was just going over the final camera check before filming could being. She was rather tall, towering a full six foot two inches. Her frame was definitely lithe, with a hint of athleticism, though graced with generous curves. Fiery shoulder length tresses framed her angelic visage, adorned with bright green eyes and full plush lips. A simple white blouse, the first few top and bottom buttons undone, exposed both her flawlessly flat tummy, with a cute little diamond naval stud, as well as the impressive swell of her pert D cup bust, straining against the confines of a skimpy black bra. A sinfully short black skirt didn't even reach far enough to cover the dimples of her sweet, spankable rear and left those seemingly endless legs on full display. The lack of undergarments was all too apparent as her hermy appendage was left free to sway. Even limp the monster must've been a good eight inches in length and when erect towered a full fourteen inches. The thing was so girthy that Jessica couldn't dream of wrapping a single hand about it. A pair of cum swollen testicles dangled beneath, each roughly the size of a clenched fist. With every little movement one could almost imagine hearing that thickened load sloshing about. With everything seemingly in order she'd teasingly call out to her co-actress. "Show time slut!~"[2015/04/15]Mistress-Herm: (Sorry if that was a bit much. I like to go all out for the opening.)[2015/04/15]*Serenity Marshal took a deep gulp, her body still shaking in nervousness. Ever since Jessica had seen what was on her phone, she'd been dreading this moment. Why'd she have to leave the bar with those guys, or even let them near her phone? At least mom and dad hadn't seen them or she'd be completely mortified. That was why she just had to hope this would end quickly... and that no one would recognize her online. She stepped out into the living room, wearing a rather modest outfit compared to her sister. A long white skirt with a light yellow blouse that was doing a much better job at hiding her body, and a pair of heels as well. Her body was different as well, standing at only five foot nine, with a much less sultry frame and a pair of B-cup breasts well hidden in her blouse, and shoulder-length brown hair. Underneath it all, however, she was wearing a frilly set of white lingerie, just like Jessica asked her to. "You don't have to call me that..." [2015/04/15]Serenity Marshal: (it's no problem. I'm not the best at outfits and everything, so let me know if it's okay)[2015/04/16]Serenity Marshal: Hello[2015/04/16]Mistress-Herm: Hello. Terribly sorry about the other day.[2015/04/16]Serenity Marshal: Oh, it's no problem. I assumed something inportant or urgent happened.[2015/04/16]Serenity Marshal: Things happen.[2015/04/16]Mistress-Herm: Unfortunately.[2015/04/16]Serenity Marshal: Still interested in the idea?[2015/04/16]Mistress-Herm: Very much so.[2015/04/16]Serenity Marshal: Do you have the reply I gave to your opener?[2015/04/16]Mistress-Herm: Sure do. Just give me a moment and I'll get my post around.[2015/04/16]Serenity Marshal: Sounds great. I might disappear for a moment in a bit (switching from mobile to home pc) so I'll let you know if I miss it.[2015/04/16]Serenity Marshal: (Okay, fully here now)[2015/04/16Her head peeked out from behind one of the cameras as her sister made her way into the living room, lips curled into a devilish little grin. She could tell a mile away her sister was very nervous and uncomfortable. "I don't know, those pictures on your phone seem to agree with me. And I bet plenty of people at school would too." she couldn't help but tease with a little giggle. Standing up, she sauntered the short distance over to her sister, that huge limp member slapping between her thighs. She so shamelessly reached out to grab her sister at the hips, pulling the girl in for a tight crotch lock, grinding her hips a bit, letting that limp cock grind against her sister's tummy. "Then again I'm not really surprised, we are sisters after all." she'd tease some more, hand trailing back to slip under her sister's skirt to give her rump a quick little squeeze, pulling the pair even more tightly together. "I've wanted to fuck you for years you know..." that hot breath washed onto her sister's ear. "And I know you've thought about it too." she went on before finally breaking the embrace and getting back to her work with the cameras. "Now come on sis, let's see what you've got on underneath." she said, even as she began to turn the cameras on one by one.~[2015/04/16]*Serenity Marshal blushed even deeper as her sister got close and comfortable with her, teasing her all the way. She couldn't help but give a little moan from the sight of her sister's massive cock slapping between her thighs, rubbing against her own belly, and that squeeze of her ass cheeks. "I-I..." she stuttered at Jessica's accusations. She'd known about her sister's 'gift' for a while, sure, but it had never really crossed her mind that they... actually fuck. Still, she didn't have much choice in the matter now, unless she wanted most of the students on campus asking her for blowjobs between classes. As she saw the cameras click on one by one, she slowly started to undress, pulling up her blouse to reveal the white bra underneath, as well as the pulling down her skirt to show the white thong underneath, no doubt showing her ass to one or two of the cameras in the process.[2015/04/16]*Mistress-Herm With all the cameras finally on and rolling Jessica took a brief moment to admire her sister strip down to her undergarments through the central camera. "Mmm... very cute." she'd tease some more. "Let's start out slow." she'd explain, all business now. "Sit on the couch and look in the end table. I left a little surprise there for you." she'd go on with a little wink. Inside was an especially large black dildo. While not as impressive as her own endowment the thing was still bordering on a foot in length, covered in thick ridges and veins. There was also a fresh bottle of lubricant for her sister to use. "I don't want to spend half the fucking film trying to fit inside of you." she'd explain, that devilish grin returning as she watched her sister's reaction closely at the suggestion.~[2015/04/16]*Serenity Marshal blushes on seeing the toy, along with the bottle of lube. She started to object, until Jessica gave her reasoning. It wasn't a bad idea, sure, but it still seemed a daunting task. Putting the thick dildo on the table and grabbing the lube she began to open it. "W-which one first?" she asked, timidly, pouring the lube on the head of the dildo and sliding one hand up and down the ebony shaft, coating it in lube while looking at one of the cameras.[2015/04/16]*Mistress-Herm Her sister looked so cute and nervous handling that over-sized toy. Jessica could feel her own loins twitching at the sight, imagining her sister's hands working her own shaft in a similar manner. It took all her self control to dismiss such thoughts. She had to stay focused, wanting the cameras to get a nice shot of her sister bringing that monster to life. "Oh it doesn't matter, whichever one you wanna get fucked in first." she explained. She dismounted one of the small hand-held cameras from a tripod, her favorite such camera for getting some nice point of view action. She made her way to the side, just out of camera shot, zooming in to get some especially good pictures of her sister.~[2015/04/16]*Serenity Marshal continued stroking and lubing up the monster dildo as it sat upright on the end table, making sure to look at the camera every now and then, especially when she leaned over to suck lightly on the thick, bulbous head, some of her spit running down the length and mixing with the lube. After another minute of teasing the dildo and lubing it up, she turned around on the couch to point her rear towards the dildo and Jessica's camera, pulling down her thong and leaving herself only clothed by her bra. She then rolled over, laying on her back and grabbing the massive dildo before lining it up with her pussy, which was already wet and ready, before pushing it in slowly.[2015/04/16]*Mistress-Herm She zoomed in on her sister's exposed cunny, watching as the moistened hole opened up to take inch after inch of that thick black rubber cock inside. "Mmm... look at you go." she'd tease some more. Finally she couldn't wait any longer and made her way into the cross fire of cameras. "Now it's time for you to take care of me..." she went on even as her free hand went for that bottle of lube, squirting a generous streak across her limp member. She made her way onto the couch, making sure her sister still had access betwixt her own thighs, straddling the girl about her mid-section. Her cock was already begging to twitch and swell with excitement, only a scant few inches away from her sister's face.~[2015/04/16]*Serenity Marshal moaned as more and more of the thick dildo slipped into her hole, stretching her out. She could barely react when Jessica straddled her chest and held that limp monster inches from her face. As one hand continued to work the dildo in and out of her cunt, she reached the other up to grab the shaft and stroke it slowly, barely able to hold onto it due to its girth, guiding the head up to her mouth to wrap her lips around it. She groaned and moaned around it, struggling to fit the thick cock in compared to the dildo she had been sucking just a minute ago.[2015/04/16]*Mistress-Herm She watched with utter glee through the view screen of her small camera as her sister opened her mouth and begin to suckle upon that monster. The thing looked so grossly oversized for her sister's small face and mouth. Her free hand would reach forward, fingers curling into her sister's hair for a nice tight grip, letting her know she wasn't getting away from that cock easily. "Mm..yeah..get my cock nice n' sloppy sis..." she moaned out softly, hips slowly working forward to send inch after inch of her growing cock past her sister's stretched lips and into her hot, moist mouth.~[2015/04/16]*Serenity Marshal started to groan louder, taking sharp breaths through her nose as her mouth was filled more and more with Jessica's cock, stretching it to the limit. She tried to keep up the thrusts of the dildo into her pussy, soon letting go of stroking her sister's shaft in order to work the dildo faster and faster, hoping to distract her from that monstrous cock stretching her moist mouth. After only a few inches of Jessica pushing in, Serenity started coughing and gagging, trying to pull her head back from it for relief.[2015/04/16]*Mistress-Herm The cute sputtering sounds of her sister beginning to cough and gag around her swelling cock made her blood boil and her testicles churn. She pulled her sister's head away from her cock slowly, watching as a few spit covered inches were removed, thick strings of saliva connecting the tip to her sister's lips before breaking messily onto her chin. "Come on sis, you can do better than that..." she teased, that cock still twitching and growing, the tip soon butting into her sister's cheek. "I need to use your mouth as much as I can before I get too big to fit inside at all." she explained rather calming before positioning her sister, by means of her hair, back at the tip. Her hips gave a quick lurch forward, instantly filling her sister's mouth fully with hot, throbbing cock, her bulbous tip jamming against the entrance of her throat.~[2015/04/16]*Serenity Marshal coughed and gasped for air as Jessica pulled out, feeling that heavy, hot cock against her chin and cheek as she tried to regain her composure. "I-I'm trying if you'd let me-!" she said, before quickly being pushed back onto the cock, silencing her and filling her mouth completely. She tried to keep calm, stopping with the thrusts of the dildo in and out of her pussy as she tried to breath in and out of her nose and relax her throat to allow Jessica to push in further. "Mmph!" was the only sound she could make while trying to get more of Jessica's cock in her mouth.[2015/04/16]*Mistress-Herm She paused only for a brief moment at the entrance to her sister's throat, feeling close to half of her cock being so lovingly massaged by her sister's suckling mouth and squirming tongue. Had her cock been much harder the angle of insertion would've been impossible. She pressed forward with her hips, pulling at her sister's hair to drag her further down her pecker. She had to lean forward a bit to bury those last few remaining inches into her sister's mouth, sighing contently as she felt her sister's nose press against her tummy and her chin into those swollen testicles.~[2015/04/16]Mistress-Herm: (I need to take a break here dear. I should be back within a half hour though.)[2015/04/16]Serenity Marshal: (Okay. Enjoying it so far?)[2015/04/16]Mistress-Herm: (Sure am. And yourself?)[2015/04/16]Serenity Marshal: (Uh huh. Very much so~)[2015/04/16]Serenity Marshal: (I'll save my reply for when you get back, just let me know when.)[2015/04/16]Mistress-Herm: (Will do.)[2015/04/16]Mistress-Herm: (I'm back.)[2015/04/16]Serenity Marshal: (Welcome back)[2015/04/16]*Serenity Marshal began to moan deeply, her throat vibrating around Jessica's cock as she was pushed down to the hilt, her tongue darting out a bit to press against her swollen balls. Finally, she began moving the black dildo in and out of her pussy again, which was certainly stretched enough for her sister's mammoth member now. Her coughing and gagging continued to subside as she became more and more used to her sister's thick cock being forced down her throat.[2015/04/16]*Mistress-Herm She held her sister down upon that lengthy, fleshy spire for a long moment. Feeling her sister's tongue dart out to tease at her testicles almost made her squeal with pleasure, lurching forward even more, as if trying somehow to force her cock further down her sister's throat. Finally she began to pull back, watching in glee as every inch of reappearing cock was seen drenched in a thick coating of saliva. She pulled back until only the tip remained, that cock looking quite a bit bigger than when it had first went in, pausing only briefly before she sank down fully again, slowly beginning to screw her darling older sister's face.~[2015/04/16]*Serenity Marshal moaned, looking up at the camera and Jessica with a pleading look when only the tip was left in, hoping that she would pull out, until Jessica simply slammed back in and began fucking her face with that slowly growing cock. Her body began to shudder from the repeated thrusts of the dildo into her pussy, before she finally came around it, her juices flowing out, coating the black monster and spilling onto the furniture. Afterwards, she made no effort to hold onto it, letting it slide out and fall onto the couch as well.[2015/04/16]*Mistress-Herm After a few moments of sliding her thickened pecker in and out of her sister's mouth it became increasingly difficult to keep up with the growing size, her sister's lips stretching even further, unable to force her way all the way down. It quickly reached the point she could no longer delve into her sister's throat, simply battering against the entrance to her throat over and over. The idea of that girthy fuck stick getting stuck in her sister's mouth seemed a rear possibility, feeling the girl's teeth dragging across the sensitive skin in a mingling of pleasured pain. Finally she pulled out, the tip dislodging with an audible pop, before grinding her cock all across her sister's adorable face, the member easily quite a bit longer that her head. As if to signal it had reached it's zenith, a thick gush of precum escaped the tip to paint her sister's lips. "Mmm, very good sis. But then again, I kinda figured you knew how to handle cock well." she'd tease with a grin.~[2015/04/16]*Serenity Marshal gasped for air as Jessica pulled out, having been close to gagging around the thickening member yet again. Some of the pre on her lips landing in her mouth as she took deep breath, staring at the camera. "I-is that so?" she asked, teasing a bit as she moved her hands up Jessica long legas and towards her plump rear. "Are you gonna fuck my pussy now~?" she added with a moan, clearly turned on enough by the experience so far, or at least somewhat good at acting like she was. She even leaned up to lick some more pre from the tip of Jessica's cock, before cleaning it off her lips as well.[2015/04/16]*Mistress-Herm Her cock throbbed in cadence to the beat of her heart, so hard and worked up from her sister's mouth and naughty words. Each throb would release another thick dollop of precum, slowly rolling down the vein riddled length, or simply plastered against her sister's face. "Oh? What's that? Does big sis want my fat fucking cock jammed up her sloppy little hole?" she'd tease, those fingers finally releasing their grip of her sister's hair, instead moving to her own blouse, slowly undoing the last few buttons. She had to switch camera hands for a moment to get out of the garment, letting it fall to the floor, her black bra soon following suite.~[2015/04/16]*Serenity Marshal reached her hands up, playing with her own b-cup breasts, still inside of her white bra, and nodding in response to Jessica's question. "Y-yes, little sis~ Please fuck my cunt with your fat cock~" She leaned further back on the couch, still looking up at Jessica and spreading her legs wider. Her pussy seemed stretched enough at a glance, and certainly soaking wet, having been pounded by the thick black dildo now laying unused now on the couch. "I want it to stretch me out, please~" she begged, licking more pre from her lips, though some of it had landed on her eyes and cheeks, and was making what little make-up she had run down her face.[2015/04/16]*Mistress-Herm She worked her way back from straddling her sister's midsection, positioning herself between her spread legs. Her knees sunk into the couch as either hand reached out, slowly running up and down her sister's thighs. She lined her throbbing crown up against her sister's cute, soaked little lips, grinding back and forth slowly, only teasing the girl some more. Her breath was hot and heavy, her hands tightening at the top of her sister's thighs, nails digging into supple flesh as she jammed forward with her hips, pulling back at her sister with her hands. The movement was too quick and too harsh, her cock glancing off her sister's sex to travel across her crotch and tummy, her hips connecting with her sister's rear with a light little smack. The cameras received a perfect view of exactly how over sized that prick was, the thing reaching well past the girl's belly button and looked as though it would threaten her lungs if inserted. "You sure?" she'd only tease some more, grinding her cock across her sister's tummy.~[2015/04/
