Sierra: 5'7", long black hair, green eyes, a slender figure, below average breasts/ass/curves, but a foot-long dick that she always has to pay attention to.

Sierra was born a futa, though she always identified more with girls and looked/sounded/acted like one. When puberty hit in middle and high school, she didn't develop much as a female - her breasts grew a bit, leaving her at about a B-cup, and she grew into an unremarkable frame. But her cock developed more than enough to make up for it, growing to a point where it was 6 inches soft and 12 inches hard. Her balls never really stopped growing - by the time she had figured out masturbation at the age of 12 or 13, she was already letting out pint-sized loads. She started having to get creative about masturbation by the time she was about halfway through high school, where each time she came, she'd produce more than quart. And by the time she started college, her apple-sized balls could let out nearly a gallon of jizz.

Erika was always on the tall side, and always excelled in sports. She really blossomed when she hit puberty in middle school, getting a curvy figure and nicely-sized breasts, and has had a continuous series of boyfriends since then. Being pretty and confident, but not stuck up, she had quite a few friends. In high school she got plenty of sexual experience with her boyfriends, although she was usually monogamous and didn't sleep around or anything. She also experimented with girls in her senior year and decided she liked it, and is looking to continue exploring that side of herself in college.

---------------------------------------------------------------------------------------

Erika wiped her forehead and let out a rush of breath as she opened the door to her assigned dorm room. The lines for the elevator had been absurdly long, so she decided to haul her enormous duffel bag up three flights of stairs. A bit harder than she was expecting, but at least it was a nice workout.

Adventurous as she was, she was excited to start college. New people, new structure, and a new city meant plenty of opportunity for exploration... in more ways than one. Erika had found herself checking out some of the other freshman girls on her way upstairs. She'd always found other girls pretty, but had only recently started experimenting sexually with them, and decided she wanted more.

She pulled in her duffel bag and closed the door behind her, stowing the bag in a corner. Turning around to survey the room, she noticed a mousy-looking girl on one of the beds and smiled broadly. "Hey there, I'm Erika. You must be Sierra?"


"That would be me," Sierra said, reaching out for a handshake, "Nice to meet you!" She had been anxious about meeting her roommate - Sierra was always a little more on the shy side, and she sometimes had a hard time connecting with people. First impressions always mattered, and she didn't want to screw this up.

As Erika began unpacking, Sierra found a chance to take a good look at her without being noticed. Sierra quietly thought to herself that she'd won the roommate lottery - Erika was built like an athlete, which meant she probably was on a team and wouldn't be getting into much trouble. And she was also incredibly good-looking - Sierra was already mentally undressing her and thinking about all the masturbation sessions she'd have with Erika's curves in mind. Sierra quickly refocused, making sure not to get too caught up in daydreaming, not wanting to explain why she had a foot-long erection a minute after meeting her roommate.

"Is there anything I could help you with?" Sierra asked, having already set up her half of the room in the most tidy and organized way she could. "And where are you from?"


"Likewise." Erika gave her new roommate's hand a firm shake. She couldn't help giving her a quick looking over as she did: Sierra was cute, in an awkward kind of way. Her eyes were an intriguing shade of green, and her face was pretty enough - though, granted, she didn't seem to put as much effort into her makeup and skin moisturizing as Erika did. Her body, however, was particularly boring, lacking any curves to speak of, and Erika quickly dismissed her fantasies of having a sexy lesbian roommate. She turned and started unpacking her bags.

"Sure, that'd be great, thanks. Could you just help take my stuff out and put it on my bed?" She was already pulling out piles of clothes and school supplies. "I'm from LA. People keep saying I'm crazy to move away from there, but... I don't know, it just got old. I like it there, but college is for trying new things, you know?" She pulled out her last pile of socks and sat down on the bed. "What about you?"


"I'm from a suburb about an hour away from here," Sierra said. "I'm not too familiar with the city because I don't go downtown much, so there's still a lot of exploring I have left to do. So I guess I'm the same as you in wanting to try new things. It's just... almost everything is new to me anyway." Sierra copied Erika's movements and sat down on her own bed, making sure to keep her dress pulled past her knees to avoid revealing the unseemly bulge of her oversized balls.

"And I guess I'm happy just staying here. I'd love to go to California some time, but in-state tuition kept me local." Sierra was trying her best not to be completely captivated by Erika's appearance, but it was proving difficult, especially with how heavy Erika was still breathing from carrying her bag and unpacking. Each deep breath she took caused her chest to rise and fall significantly, drawing attention to her breasts and providing a clear outline through her shirt for Sierra to see. Even with Sierra's hyperactive sex drive, it wasn't like her to get turned on just by being near an attractive person, but this was different. This was her college roommate - which meant she was going to know her more intimately than any other girl she'd ever met.

Between being distracted and not being the most skilled at keeping conversations going, Sierra struggled to find a question to keep the small talk going. After a pause, she asked, "So... uh... You know what you want to major in?" As she spoke, she shifted her hands to her lap, doing her best to cover up and suppress her growing erection.


Erika smiled sympathetically as her roommate, obviously nervous, struggled to keep the conversation going. Aww, she was adorable! She found herself liking the shy, mousy girl - who, clearly, had the hots for her. Erika had plenty of experience with being the object of a crush, and she could see it a mile away - especially in someone as socially inexperienced as Sierra. Maybe there was a hope for sexy roommate shenanigans after all.

She was about to save the conversation herself when she heard Sierra speak. She laughed softly. "Nope, not even slightly. I got here on a volleyball scholarship, so I think I'll focus on that for now. In fact, I've got practice soon, so I should get changed. No peeking, alright?" She winked. She didn't have practice soon - those didn't start until the next week, after giving the team a chance to settle in. But she wanted to get out of this room and explore the campus, and it was too much fun to tease Sierra.


If Sierra wasn't already aroused, the flirtatious wink and the idea of Erika changing in the room was enough to change that. She pressed down harder on her crotch, trying her best to keep the growing bulge from showing through her dress. When her dick continued to rise, straining against her arms and making the resistance painful, Sierra made a split-second decision to roll onto her stomach under the guise of obeying Erika's request for no peeking. In a shrill voice that was higher-pitched than her normal tone, Sierra said, "Ok!" doing a poor job of masking how flustered she already was.

Sierra was both disappointed and relieved that Erika was going to be leaving so soon. On one hand, she wanted to get to know her roommate a little better - Erika seemed like she was the stereotypical Cali girl and volleyball player - but Sierra knew that there was always more to someone than what she could see at the surface. But on the other hand, her cock was at full mast and her balls were already churning, preparing to release another massive load. The sooner Erika was out of the room, the sooner Sierra could take care of herself and regain her composure.

While waiting for Erika to change, Sierra pulled out her phone and tried her best to look normal, whatever normal was. When she thought Erika wouldn't be looking, she snuck a quick glance. She found herself staring Erika right in the eyes, caught red-handed in the act of peeking. Damn it, Sierra thought, I've already ruined it. Now she thinks I'm a perv.

"And by OK I meant, 'OK, I'll only peek a little bit' ...or something like that," Sierra said, nervously trying to defuse the situation. Blood rushed to her pale face to form a huge blush, making it more than obvious that she was embarrassed and uncomfortable that she'd been caught.


Erika turned around as she stripped to her bra and panties, but then looked over her shoulder to see if Sierra was paying attention. Just as expected, it wasn't long before their eyes met, and Erika gave her a knowing grin. This was strange for her - she wasn't normally a tease like this, usually preferring to be open and direct about her interests, but her roommate was so shy, and awkward, and obviously turned on, that she just couldn't resist. She was starting to realize she liked being dominant with other girls, enjoying the idea of sweeping flustered cuties off their feet.

Her grin widened at Sierra's response. "Oh? And just why were you peeking?" She turned around fully, revealing her sculpted body and nicely rounded curves. She stopped herself from giggling, not wanting to make Sierra too uncomfortable. If she was ever going to make a move, now was the time: she walked slowly over to the bed, sensuously swaying her hips and wearing a flirty expression. "See something you like?" she asked, low and seductive. Classic, if a bit cliched.


"Yes... I mean- no... I- yes," Sierra said. Then, rapidly picking up the pace of her speech, she continued, "You're really attractive and everything about you is basically perfect but I'm not sure about this and I don't think you're sure about this either and I can't really explain why but just take my word for it."

Sierra's motivation was simple enough. She wasn't really comfortable with her dick, and she had always done her best to hide it. It was why her wardrobe consisted mostly of longer sundresses and baggy clothes. Only her parents and her best friend from high school even knew she wasn't a normal girl, and even with them, she rarely talked about it. She was always afraid that she'd be judged for it, especially because of her freakish size and cum output. So to show it off to her roommate less than 10 minutes after meeting her was not a part of Sierra's plan. It was something she was going to have to do in time out of necessity, but now didn't have to be that time.

But as Erika sauntered over to Sierra, swaying her hips back and forth in an over-exaggerated attempt to be seductive, Sierra reconsidered. Maybe now was the time. It was clear enough that Erika wanted to fool around, but that was with what she perceived to be a female version of Sierra. Was Erika a lesbian? What would she think of an oversized male package?

There was only one way to find out. Sierra said, with newfound confidence, "OK, actually. I can explain why. But before I do, you have to promise to not freak out. And you have to promise to not tell anyone."



Erika's smirk faded, and she gave Sierra a sympathetic look as she tried to stammer her way out of the situation. "Hey, if you really don't want this that's okay, sorry if I made you uncomfortable. It's just that you seemed, you know, interested." Erika mentally kicked herself. Of course Sierra couldn't be comfortable with this. She was barely holding it together just talking to her -- how could she be expected to handle Erika outright stripping and all but inviting her into bed? Once again, she questioned why she was suddenly acting so differently. No doubt things would be exponentially more awkward between them in the future. Screwing up your relationship with your roommate on the first day -- way to go, Erika.

But then Sierra's tone shifted, and Erika raised her eyebrows in surprise. "Um, okay! Sure, I promise." She waited anxiously, not quite prepared for an emotional revelation from this girl she just met. She was even more confused when Sierra rolled back over and sat up, saying nothing, but apparently trying to show her something. It took Erika a moment to realize that the disruption in the fabric running down her leg wasn't just a result of baggy clothes, but was in fact caused by something underneath them. Something long, and thick, and unwieldy. Judging by Sierra's beet red face and pained expression, it was something she didn't enjoy showing off, either.

Slowly, it dawned on her. "Is that your...? I mean, are you a... transsexual, or something?" Sierra turned her head, obviously ashamed, and Erika took that as a yes. She sat down on the bed beside her. "Because I'm okay with that, if you're okay with me. I hope you don't mind me saying, but that thing is huge." She did her best to sound impressed rather than disgusted, as she knew Sierra would expect.


The compliment went a long way towards boosting Sierra's confidence. It wasn't that she didn't already know she was huge, but that the tone of Erika's voice suggested she wasn't disgusted. If anything, it seemed like Erika was in awe. Maybe she was actually OK with it. With that in mind, Sierra looked up, comfortable enough to explain, "I'm not really a transsexual, no. I have both sets, so hermaphrodite would be closer to the truth. I've just always felt, looked, acted, and sounded more feminine. And the way my body is - it's totally natural. I haven't taken hormones or anything like that. This is just how I am. You're not freaked out by it or anything?"

Sierra was experiencing a weird combination of emotions. She was relieved that Erika seemed to be dealing with the revelation just fine. Starting off their relationship as roommates this way was probably going to pave the way to always being open and honest with each other. They were having a genuine conversation, and Sierra was explaining her body in a way that she'd only ever done once before. But at the same time, she was painfully aroused. A girl who could easily be a model if she wanted to was sitting next to Sierra. And that girl was in her underwear. It was all Sierra could do to not just stare into Erika's cleavage while talking to her. As she spoke, her dick had begun leaking precum, forming a small damp spot on her dress at the tip of her now rock-hard length.


Erika nodded slowly. "You're a hermaphrodite, huh? That's new to me... but no, I'm not freaked out at all. I just think you're cute, whatever you've got in your pants." She was so glad Sierra seemed to be getting more comfortable. She got the impression this shy girl was used to covering up her secret. And if she expected Erika to be freaked out, she probably didn't have a high opinion of it either. Poor, um, girl -- Erika was starting to feel genuinely protective of her. But on the other hand, she had a huge dick that Erika was curious to see. Judging by her reaction, she likely had no sexual experience, which normally would have been a bit of a turnoff. But in this girl, with her fragile, cute appearance juxtaposed with that log between her legs, it only made Erika more eager to show her the ropes.

"Looks like it works just fine too," she mused, noticing the wet spot spreading from the tip of the bulge. Erika had to admit to herself, she liked the reactions her body got. And she had been trying to get Sierra all hot and bothered with her impromptu strip show, even if she hadn't quite expected this result. "Listen, I get that this must be weird for you, having just met me and all, so feel free to say no. But I'd really like to see it." She bit her lip. Of course, she was sure Sierra wouldn't dream of saying no -- not with a hardon like that -- but she didn't want her to feel pressured.



Sierra's apprehension and embarrassment were turning into excitement, and she was only getting more and more turned on. Erika wasn't just OK with Sierra's oversized manhood. If the lip bite was any indication, Erika was actually getting turned on by it. And she wanted to see it. Sierra was, by all accounts, totally inexperienced in everything other than masturbation, but even she knew that whipping her dick out and showing it to Erika meant that she'd be cumming shortly after.

Sierra didn't even hesitate. She knew in the back of her mind that playing around with her roommate just after meeting her might make things awkward down the road, but that was a problem she could solve later. Right now, she needed to cum, and a Cali bombshell was sitting in front of her, likely willing to make that happen.

Wordlessly, Sierra slid her underwear off underneath her dress, dropping it to the floor in record time. She then pulled her dress off over her head, leaving her lower half totally bare with only a lace bra covering her top. Her foot-long cock protruded from her crotch, jutting outwards and upwards towards Erika on full display. It was pulsating and twitching in tandem with Sierra's heartbeat, practically begging for attention. Beneath it hung her apple-sized balls, burdened with the weight of the load they'd been working so hard to prepare and still churning to produce more. Playfully echoing Erika's tease from earlier, Sierra asked in her best sultry voice, "See something you like?"



Erika watched eagerly as Sierra stripped -- it was only fair, after all, since she'd caught her sneaking a peek at her own half naked body. She held her breath as Sierra pulled her dress off, revealing the massive, throbbing, juicy cock attached to her. For a long moment, she was speechless; she'd never exactly been a size queen, and the biggest dick she'd ever seen in person had been about eight inches. This one looked half again as long, and much, much thicker. Attached to such a small girl, it looked almost ridiculous. Almost.

"Wow." It was all she could say. Still sitting on the bed, she shifted closer to it, mesmerized by the copious precum dripping from the angry red helmet. Wordlessly, she reached out and gave the shaft a light stroke. The thing was scaldingly hot to the touch, and much harder than she expected given its size. Her hand reached the base of the enormous shaft, and she noticed Sierra's churning, apple-sized balls. "Oh, wow," she repeated, not having the vocabulary to properly describe what she was seeing. "Uh... yes. Yes, I do."



Sierra wasn't sure if she was in the driver's seat or not, but she figured she could give Erika a little nudge in the right direction. "It's all yours to play with," Sierra said, sitting back and feasting her eyes on Erika's body. She quivered and tensed as Erika explored her shaft, dripping more and more pre-cum with each passing moment. It felt entirely different when it was another person stimulating her, and much, much better.

Sierra's balls were beginning to ache, reminding her that she hadn't unloaded in several hours, having been preoccupied with moving in. That reminded her of an important detail that Erika didn't know. "And fair warning: when I cum, I cum a lot," Sierra said, doing what she thought would be enough to prevent any unpleasant surprises.



"Heh. Alright, thanks for the warning." Erika wasn't quite sure what to do with Sierra's cock. It was far too big to fit inside her, of course, and even fitting the tip into her mouth would be a challenge at best. She decided to stick with playing with it, for now -- the substantial weight of the thing made it that much more satisfying, and she wanted to see what Sierra considered "a lot" of cum. Judging by the size of those balls, that might have been an understatement...

Before continuing further, Erika reached behind her and unclasped her bra, smiling knowingly as she dropped it to reveal her huge, firm breasts, topped with hard pink nipples. Then she got to work, wiping up a splash of precum and spreading it all along the sensitive shaft before grabbing it with both of her practiced hands and giving it long strokes. She'd never been able to fit both her hands on a dick before; this thing was a challenge, for sure. She slowly sped up her jacking, the repeated movement making her boobs jiggle as Sierra's precum dripped onto them. Then she leaned forward and began tonguing the leaking slit, the pre flowing into her mouth like a drinking fountain.



As Erika picked up the pace, Sierra could already feel her orgasm building. Erika was clearly very skilled in the art of handjobs, and though it was still going to take her some time to coax the cum out, she was doing a much better job than Sierra could despite having no experience with such a gargantuan cock. Whether it was because Erika was just that talented or because it felt so much better being pleased by another person, Sierra wasn't sure.

Either way, Sierra was too absorbed in throes of pleasure from Erika's efforts to do much more other than sit back and let it happen. With each pump of Erika's hands, Sierra let out a soft moan, vocalizing her enjoyment and letting Erika know that what she was doing was working. Watching Erika's bare breasts bounce up and down as part of her jerking motion turned Sierra on even more, and she felt like her dick was somehow getting even harder, her veins bulging outward and entire shaft throbbing with need. When Erika began slurping and drinking all the precum Sierra was leaking, Sierra leaned forward, putting her hands onto Erika's shoulders for support. She pulled Erika closer, trying to encourage her to take the very tip into her mouth.



Erika grunted in surprise as Sierra tried to push more of her cock into her mouth. Well, she was certainly eager -- Erika took it as a compliment to her handjob skills. She pushed her head forward, giving in to Sierra's silent request, but the fat thing just didn't want to push past her lips. After a few seconds though, with some maneuvering, she finally managed to pop the ridge of the helmet all the way inside her mouth, pouring its ever increasing flow of precum directly down her throat. It'd take some work to get out, Erika thought worriedly, but it was worth it for the look of pure ecstasy on Sierra's face. She looked up at her with a triumphant expression (or as close as could be managed with her lips stretched to capacity) and continued her ministrations, awkwardly continuing to lick the leaking cum slit while her jacking became more and more rapid. She could tell Sierra was getting close by her expression and her rapid breathing.



As Sierra's pleasure mounted thanks to Erika's continued efforts, her moans became less controlled, getting progressively higher-pitched and louder. That Erika could actually fit the entire tip of Sierra's mammoth cock inside her mouth was impressive, and Sierra pulled her hands off of Erika's shoulders to let her go at her own pace. Now with nothing else to do, Sierra shifted her focus to her pussy, lifting up her balls with one hand and sliding her other hand past them to gain access. It was sopping wet and very sensitive after how much it had been neglected, and just gently rubbing over it with one hand was enough to send shivers up and down Sierra's spine. The sensation of being pleased on both her male and female parts at the same time was something Sierra had never experienced before, and after just a short moment, it was enough to push her over the edge.

"Cumming!" was the only warning Sierra gave, and even then, it was a little too late. As she said it, she unleashed a massive blast of jizz into Erika's wide-open mouth, filling it beyond capacity; some of the salty load made its way down Erika's throat, some stayed in her mouth, but the vast majority shot back out onto Sierra's cock, Erika's body, and the floor of the room, propelled by the force of the orgasm and lacking anywhere else to go. It already looked like Erika had been on the receiving end of a gangbang -- her chest was covered in what was probably a pint of pearly-white cum. And all of that was just from the first jet -- there was still a lot yet to come.



Erika gagged and tried to pull Sierra's enormous dick out of her mouth as the first jet of cum hit her in the back of the throat hard, practically forcing her head back as a large amount of the sticky white goop forced its way into her stomach. She was amazed to see far more cum gush back out of her lips to spray all over the two of them, recovering Sierra's cock and splattering onto the floor as well -- and all of this in only the first couple seconds. Erika managed to pull the erupting monster out of her mouth just before the second, even larger jet hit her in the face, immediately covering it and making it impossible to see the rest of Sierra's glorious orgasm. The sounds of splattering mixed with the girl's ecstatic moans as Erika's body was covered in layers of thick spunk. "Sierra -- holy shit!" She cried as she was covered again and again in the girl's absurd output.



Sierra's orgasm had hit her so forcefully that all she could do was throw her head back, close her eyes, and moan in response to the overwhelming pleasure. Each time her cock spasmed, she could feel the sheer volume of her load distend her shaft before shooting out and onto Erika. It felt like bliss to Sierra, drowning out all other sensations she had and directing her entire focus towards the liquid escaping from her cock. Then she heard the wet splattering noise as it forcefully made contact with Erika's face, followed by the lewd sounds of it dropping to the rest of Erika's body and the floor below. By the time that happened, another jet was working its way up Sierra's shaft, getting ready to repeat the process again.

Sierra knew that after the Erika had to be completely soaked after the first few blasts of cum, but her orgasm dragged on and on, gradually declining in quantity and intensity but feeling no less pleasurable. After what felt like an eternity but was probably closer to a couple minutes, Sierra was finally finished. Her legs were weak and here balls felt emptier than they'd ever been since she first hit puberty several years ago. Still panting heavily, she finally opened her eyes to see exactly what she'd done to Erika: the girl was absolutely coated, and looked like she was more semen than person. Sierra laughed and said, "I warned you!" as she took in her handiwork. Sierra had to admit that the sight of Erika being completely coated in her prodigious output was really hot, and her softening cock, still dripping out the last remnants of her orgasm, was already starting to get hard again. But Sierra didn't need to cum again -- well, at least not in the next 5 minutes -- and she needed to help Erika clean herself up.

"Here, let me get you a towel," Sierra said as she got up and wobbled cautiously to her closet, her legs not fully able to support her. "...or several," she added after glancing back towards Erika again.



"That you did," Erika replied weakly, her brain still not processing what had just happened. She knew Sierra's cock was huge, but... this? How was this even possible? She licked the thick cum from around her lips, noticing it's salty but not unpleasant taste. How could she even hold this much cum inside her scrawny body? She found herself giggling slightly, then moving into an outright laugh at the absurdity of the situation as she took the towel from Sierra and wiped her face. It was the only appropriate reaction, really. With her face mostly clear of jizz, she looked her roommate in the eyes, silent for a moment, then burst out laughing again. "Wow, Sierra, that was... that was quite something."



Sierra didn't really expect the laughter from Erika, but it did make sense. They had just met, and Erika was already coated in literal buckets of Sierra's cum. Plus, that was Erika's first experience with just how much Sierra could produce. It was the norm for Sierra, but to Erika, it was probably magnitudes more jizz than she'd seen in her entire life so far. Sierra knew she was a freak of nature, but she was just so used to it that she hadn't expected such a strong reaction.

"But did you like it?" Sierra asked, "Because that's pretty normal for me. Maybe a bit more than usual, but nothing out of the ordinary. And there is plenty more where that came from." She pointed to her dick as she spoke, which was now at half-mast and still getting harder. Sierra's libido was off the charts, and she still had an extremely attractive naked girl in front of her, so she couldn't help herself. "Though maybe not right now," she added, trying to make sure Erika wasn't scared away.



"Like it? Jeez... I think I was too shocked to think about whether I liked it or not. It's really hot that you cum so much -- but maybe we should find somewhere else for you to unload next time, okay?" Erika motioned to her still mostly cum covered body and giggled again. The smell of Sierra's cum was quite strong; it got into her head, making it hard to think. "And you're ready to go again? God... Maybe we should give that thing a break, yeah. But I'm definitely interested in seeing it again."

Erika finished wiping herself off as best she could, although there was still a near-invisible sticky coating on her skin. "Anyway, I should probably go wash up. Try not to flood the room while I'm gone!" She gave Sierra's hardening dick a playful squeeze before going to take a much needed shower.


---------------------------------------------------------------------------------------


Over the course of the week, Sierra found that she had a problem - her dick was growing, and fast. When she woke up the next morning to take care of herself in the shower, she found that her dick had grown at least a couple of inches overnight. Sierra wasn't sure what to do about it other than carry on with her life, but each time she relieved herself, she could tell that she had gotten noticeably longer and thicker. By the end of classes on Friday, she had gotten so big that the tip of her dick could reach her mouth when she was standing up. She could measure it when it was soft with a ruler -- it was still only 9 inches then -- but she could only estimate its full length as somewhere between 2 and 3 feet. It was kind of hot to have such a massive member, but Sierra had to admit she was at least a little worried about what she'd have to do if the pace kept up. Thankfully, the increased size didn't really seem to be getting in her way. Her body seemed to be adapting to the change very well, and she never felt off-balance or overburdened even when she got hard. And because it was still manageable when flaccid, she didn't have to worry too much about exposing herself to the world. What she couldn't hide as well was that the rest of her body also seemed to be growing, too, but at a much slower pace. Her balls had never stopped growing even after puberty, but over the week they had picked up the pace, reaching the size of grapefruits, and her loads had gotten much bigger along with them. Her previously flat chest was taking on a more rounded shape -- her breasts were still below average, but she actually needed to wear a bra and had cleavage to speak of. Sierra had also noticed her pants getting tighter around her hips, not to a point where she had to buy new clothes, but enough to bring attention to the fact that she was certainly filling out. Her body was becoming much more feminine... except for the one big exception that she worked so hard to hide.

She had tried to not bring it up Erika, afraid of what her roommate might think. Erika reacted surprisingly well to Sierra's foot-long dick and output of a couple gallons of cum, but what would she think about double those? What would she think about the idea of Sierra growing so quickly in just a week? Sierra was able to still talk and converse with Erika, and she enjoyed their conversations, but any time during the week that the conversation started to go anywhere sexual, Sierra tried to change the subject or quickly pivot into something else.

But by Friday evening, Sierra had finally worked up the courage to talk to Erika. Erika was going to find out about Sierra's dick eventually - whether it was because of morning wood, an accidental walk-in, or something else, Sierra knew she couldn't hide her body from her roommate forever. Plus, Erika had seemed nonchalant about the more immediately visible signs of Sierra's growth, so maybe she wouldn't be too shocked by the growth of her cock, either. When Erika had started to steer a conversation they were having in a more flirty direction, Sierra said, "So uh... you know how I've kind of been sexually distant this week? I wasn't really sure how you'd react to something but I think I have to tell you eventually... My dick has been getting bigger."



Erika knew Sierra expected her to be freaked out by her impossibly huge endowments -- and to be honest, on some level she was. As far as she could tell it shouldn't be possible for a dick that large to be as hard as it was, let alone for a waifish girl like Sierra to even hold what must be two gallons of cum inside her body. But on the other hand, that just made it hotter; she was several times better endowed than any guy she'd ever been with, and the rest of her body scratched her itch for a cute, feminine girl. On that note, despite her interest in exploring her sexuality in college, Erika had made no attempt to come on to other girls so far, despite several clear opportunities to do so. She found herself wanting to fully explore her relationship with Sierra before moving on to anything else, at least for the time being.

Which was why Erika was both relieved and surprised when her roommate told her the reason for her sexual frustration. "Bigger? Like, how much?" Her eyes flicked down toward Sierra's thighs to check for any conspicuous bulges, then back up to Sierra's face. She blushed. "I mean, I could tell you were filling out elsewhere -- you look good, by the way -- but I didn't even think your dick could get any bigger." Erika already had sex on the brain, which was what brought them to this line of conversation, and this just made her hornier. She could read Sierra's expression, though: this was not something she was proud of. As much as she understood her roommate's discomfort with her body, it was starting to frustrate her. "So can I see it? Shit, Sierra, I thought you realized I like how big you are. This is just turning me on even more."



"OK, OK, yeah. Sorry if I'm too hesitant about things. It's kind of hard to go your entire life being told to hide a part of your body and then immediately pull a one-eighty and be comfortable with it the moment you find someone who likes it. If you ever want something from me, I won't mind you being more assertive about it. For instance, asking to see it...," Sierra said as she pulled down her pants, "...is a really easy instruction that I know how to follow." Sierra wasn't sure where she got the confidence to be so bold and nonchalant about whipping her dick out, but it felt good once she'd done it.

Sierra realized that she was still soft when she'd made her grand reveal. Speaking quickly before Erika could laugh at her or accuse her of being crazy and making things up, Sierra added, "It it's soft right now, so it's actually not that big. I mean, you can see my balls are a lot bigger if you paid attention to them last time," and then, seeing the opportunity for a fun surprise, "but you'll just have to find out for yourself how big I get when I'm hard." What the hell, Sierra thought to herself. She'd gone from unable to drum up the confidence to even talk to Erika about her growth to letting Erika experience it first hand in a matter of a day.
