Jessica is a college student with a secret: whenever she cums, her dick grows slightly bigger. Eva, her roommate, is a gym bunny who dreams of growing huge.

Chapter 1: Introduction

Jessica's tall, strong body lay sprawled across the bed, her long blonde hair fanned out across the pillow like a golden halo. The dim moonlight cast a warm glow over her bare skin, outlining the curves of her muscular legs and the gentle swell of her breasts. She lay in a deep, peaceful sleep, her chest rising and falling in a steady rhythm, her head resting on her arm.

Eva, her roommate, had been up late studying, but her eyes were too tired to focus on her textbooks. She stood up from her desk, stretching her arms above her head, and decided to take a break.

Her eyes landed on Jessica, who was already fast asleep. Eva walked over to the bed, her gaze lingering on Jessica's lithe, powerful form. She was both intimidated and drawn to Jessica's strength, her muscles defined and toned from years of swimming and running. Eva, on the other hand, preferred the gym, where she could lift heavy weights and watch her own body grow and change.

As she looked down at Jessica, she noticed something peculiar. She leaned in closer, her blue eyes scanning Jessica's body, and her brows furrowed in confusion. There, nestled between Jessica's legs, was something she hadn't expected.

Eva's eyes widened in surprise, her jaw slackening slightly. She blinked, rubbing her eyes as if to clear her vision, but the sight remained the same. A small, delicate dick lay softly against Jessica's thigh, barely visible against her tanned skin.

Eva's mind raced with questions. She knew Jessica was private, often disappearing into the bathroom for long periods after their evening workouts. But this... this was something else entirely. Her curiosity piqued, Eva found herself unable to look away.

Suddenly, Jessica stirred in her sleep, her hips shifting slightly.

Eva's eyes widened as she watched, her heart pounding in her chest. She couldn't believe what she was seeing. Jessica's tiny dick seemed to... grow.

"What the...?" Eva whispered to herself, her brows furrowing as she leaned in closer, her eyes scanning the length of Jessica's body. She wasn't dreaming this, was she?

As Jessica's delicate member hardened, Eva was both surprized and disappointed in it's small length earnestly jutting from her roommates form. In the dark night air, it looked little more than an oversized clit. Jessica's breasts heaved rapidly, her breaths coming in starts as Eva studied Jessica's appendage.

Suddenly, accompanied by a sharp intake of breath, Eva was showered with small droplets of cum spurting from her friends tiny dick. Shocked, she found some get into her mouth, the taste delicious. Hurriedly, Eva jumped into her bed, attempting to hide from what had just transpired. She found a finger slipping into her moist need comforting.

Unbeknownst to Eva, Jessica's dick plumped slightly as she returned to regular sleep.

Although the growth was small, a noticeable change had occurred.

The next morning, Eva woke up with a start, her head still buzzing with the events of the night before. She looked over at Jessica, who was still fast asleep, her chest rising and falling gently. Eva's gaze dropped to the area between Jessica's legs, and she hesitated before blurting out, "Jess, are you awake?"

Jessica stirred, her eyes fluttering open to find Eva standing over her, a strange look on her face. "Morning," Jessica mumbled, stretching her long limbs.

She yawned widely, her green eyes still heavy with sleep. "What's up?"

Eva hesitated, her eyes flicking briefly to Jessica's crotch before meeting her gaze. "Uh, nothing. Just, uh, woke up and saw you were awake. That's all."

Jessica raised an eyebrow, shifting to sit up in bed. "You sure everything's okay? You're acting kind of weird."

Eva bit her lip, her eyes darting away from Jessica's. "Yeah, I'm fine. Just, uh, thinking about our workout later.

Wanna hit the weights together?" Eva changed the subject, hoping to throw Jessica off the scent. She knew she was acting strangely, but she couldn't shake off the image of Jessica's tiny dick from the night before.

Jessica looked at her roommate, a small smile playing on her lips. "Sure, why not? You know I can't say no to a good sweat session." She swung her legs out of bed, standing up and stretching her arms over her head.

Eva forced herself to look away, her heart pounding in her chest. She had never seen a girl with a dick before, and she was both fascinated and confused by the sight.

It was small, much smaller than she had imagined, but it was undeniably there. She couldn't help but wonder how Jessica felt about it, if she was comfortable with it.

As they got ready for their workout, Eva found herself stealing glances at Jessica, trying to catch a glimpse of her dick again. She felt guilty for invading her friend's privacy like this, but she couldn't seem to help herself. There was something about it that she found strangely alluring.

"You okay, Eva?" Jessica asked, noticing her roommate's distractedness.

She was pulling on a sports bra, her long blonde hair tied back in a messy bun.

Eva snapped out of her trance, blushing slightly. "Huh? Yeah, I'm fine. Just zoned out for a bit. Let's go, shall we?" She grabbed her gym bag and followed Jessica out of their room.

As they walked to the campus gym, Eva couldn't shake off her curiosity. She needed to know more about Jessica's condition, but she didn't want to pry. She decided to approach the subject gently, hoping Jessica would open up on her own.

"You know, I've always admired your dedication to fitness," Eva started, breaking the silence between them as they walked. "It's not easy to keep up with your routine, especially with all the classes we have."

Jessica smiled, appreciating the compliment. "Thanks, Eva. It helps me stay sane, to be honest. Plus, I enjoy the feeling of pushing my body to its limits."

Eva nodded, her mind racing with questions she wanted to ask. She took a deep breath and decided to dive in. "Have you ever thought about... enhancing your body in other ways?

Like, say, gaining muscle?" Eva asked, trying to keep her voice casual.

Jessica looked at her, a hint of surprise in her eyes. "Well, yeah, I guess. I mean, I've thought about it. Who doesn't want to be stronger, right? But I've never really done anything about it. Why do you ask?"

Eva shrugged, trying to play it cool. "No reason. I was just wondering if you had any tips or tricks. I've been trying to bulk up for a while now, but it's been a bit of a struggle."

Jessica chuckled, giving Eva a playful nudge with her elbow.

"You know, you could always just hit the protein shakes harder. And maybe lay off the carbs a bit."

Eva laughed, rolling her eyes. "Yeah, yeah, I've heard it all before. But you know what I mean. Sometimes I feel like I'm stuck in neutral, no matter how hard I push myself."

Jessica paused for a moment, her eyes scanning Eva's muscular frame. "Well, have you tried HIIT? High-Intensity Interval Training? It's a killer workout, but it can really help you pack on muscle."

Eva nodded, her mind already racing with new workout ideas.

"Yeah, I've heard of it. Maybe I'll give it a shot. Thanks, Jess."

As they reached the gym doors, Jessica turned to Eva, a thoughtful expression on her face. "You know, if you're really looking to make some changes, you might want to consider some different... approaches. Some people swear by weird diets or supplements, but I've never been a big fan of that stuff."

Eva raised an eyebrow, intrigued. "Oh yeah? Like what?"

Jessica hesitated for a moment, her gaze flicking to Eva before looking away. "Well, there are these... methods.

There is this one I've heard of called GrowYourGirl, it's a pretty hectic female muscle enhancement supplement. I've heard of some bad interactions where it made woman's breasts balloon out though. " Jessica's voice trailed off, her gaze slipping to Eva's chest. "Honestly your bra is looking a little small."

Eva brought her hand up to cover her chest, feeling somewhat self conscious. Her bra had felt tight this morning, and pinched her breasts at the sides in a way she didn't remember. She would have to check out this supplement later.

"Thanks for the tip, Jessica. I'll look into it." Eva replied, opening the gym door and holding it open for Jessica.

As they entered the gym, the sound of clanging weights and grunts filled the air. Eva took a deep breath, the familiar scent of sweat and iron grounding her. She loved this place, the way it made her feel strong and empowered.

They headed to the free weights section, grabbing a pair of dumbbells each. Jessica started with her usual warm-up, her tall frame moving fluidly as she lifted the weights. Eva watched her for a moment, her mind still lingering on their earlier conversation.

She couldn't shake off the image of Jessica's tiny dick, and she found herself wondering if it had anything to do with her unusual muscle growth. She had never heard of such a condition, but then again, she wasn't exactly an expert in the field.

As Jessica finished her warm-up, she turned to Eva, a smile on her face. "Your turn, champ. Show me what you've got."

Eva grinned back, feeling a rush of adrenaline as she lifted the dumbbells. She started with a light set, wanting to ease into her workout.

As she curled the weights up, she felt a familiar burn in her biceps. She liked the feeling, the sensation of her muscles working hard.

"You're pretty strong, Eva," Jessica commented, watching her roommate intently. "What's your secret?"

Eva shrugged, trying not to focus on the fact that Jessica was staring at her. "Just a lot of practice, I guess. And probably a little bit of genetics."

Jessica nodded, her eyes still on Eva. "Yeah, genetics play a big role. But I think there's more to it. You seem to have a...

certain drive that I admire. It's like you're always pushing yourself to be better, to be stronger."

Eva flushed at the compliment, appreciating Jessica's words. "Thanks, Jess. That means a lot."

They continued their workout in comfortable silence, the clanking of weights filling the air. After a few sets, Jessica sat down on a nearby bench, wiping the sweat from her brow.

Eva found herself pushing the limit today, going up in every weight she did. She especially enjoyed the feeling of strength, and was excited for her progress. She could feel Jessica's eyes on her body as she pumped iron, longing for the feeling of her hands and lips instead.

As they made their way home, collecting food on the way, Eva googled the supplement GrowYourGirl, and decided to order a month to give it a go.

They spent the rest of the evening watching shows and studying together, before Jessica turned in for the night. Laying in the darkness, Eva waited for the soft snore of sleep before slipping soundlessly out of her bed to catch a glimpse of her roommates dick again. She knew it was wrong, but there was something that was drawing her to Jessica's dick. With a trembling hand, she gently reached out her thumb and forefinger to stroke her friends length . As she did so, Jessica let out a soft moan in her sleep. Eva quickly pulled her hand away, her heart racing. She couldn't believe what she had just done. She had just touched Jessica's dick, and she had liked it.

She knew she should go back to bed, but she couldn't resist the urge to look at it again. She reached out her hand once more, this time with more confidence, and began to stroke Jessica's length gently. As she did so, she could feel it growing in her hand. She watched in awe as Jessica's tiny dick hardened in her hand.

It was happening again, just as she had seen last night. It was growing, albeit slowly, but it was definitely getting longer and thicker. Eva's breath hitched in her throat, her heart pounding in her chest. She couldn't believe what she was witnessing.

She glanced over at Jessica, who was still fast asleep, her chest rising and falling steadily. Eva felt a wave of guilt wash over her, but she couldn't stop herself. She wanted to see how big it would get, how much it would grow.

She continued to stroke Jessica's dick, her hand moving up and down its length. Inpercieveably larger than last night, Eva used slow, deliberate strokes to bring her sleeping friend to climax. Opening her mouth once more, she greedily consumed what little cum came in pathetic squirts before slinking back to bed to play with her wet folds.

Jessica rolled over and sighed, almost moaning in her sleep as the post-orgasmic glow lasted.

Eva stared up at the ceiling, her mind racing with thoughts and questions. She had masturbated her roommate, a woman with a tiny dick, and she had enjoyed it. She felt a mix of guilt and excitement, her body still tingling from the experience.

The next morning, Eva woke up with a start, her hand still between her legs. She quickly pulled it away, her cheeks flushing with embarrassment as she remembered what had happened the night before.

Her breasts felt tender as she struggled to clasp her bra, and her titflesh spilled over the tops of her cups. Frowning at her weight gain, Eva struggled to get her jeans over her muscular thighs as she dressed for the day. Her shoes felt tighter than usual, and she wondered if it was maybe just that time of the month again.

Having dressed, she took one last look at Jessica, her loins dampening at the thought of last night, before heading to class .

Throughout the day, Eva found her mind wandering to thoughts of Jessica. She couldn't shake the image of her friend's tiny dick growing under her touch, or the way it had felt in her hand. She felt a strange mix of guilt and excitement, unable to decide if she should be repulsed or intrigued.

As they sat in their shared biology class, Eva found herself stealing glances at Jessica out of the corner of her eye. She was sitting at the desk in front of Eva, her long blonde hair pulled back in a ponytail, her shoulders broad and muscular.

Eva couldn't help but admire Jessica's physique, her green eyes flicking over her friend's lean body. She tried to focus on the lecture, but her mind kept drifting back to last night.

The professor, Dr. Harris, was droning on about cellular biology, but Eva wasn't listening. She was too busy watching Jessica, her eyes drawn to the way her friend's arms flexed as she took notes.

Suddenly, Jessica turned around, her eyes meeting Eva's. Eva quickly looked away, her cheeks flushing with embarrassment. She hoped Jessica hadn't noticed her staring.

The last thing she needed was for her roommate to catch her checking her out like that. Especially after what she had done last night.

Jessica handed Eva a note, whispering, "Hey, want to grab lunch together after class?"

Eva nodded, grateful for the distraction. "Sure, that sounds nice."

The rest of the class passed uneventfully, and soon enough, they were making their way to the campus cafeteria. As they walked, Eva couldn't shake off the feeling that Jessica was looking at her differently. She had noticed her roommate glancing at her several times throughout the day, her eyes lingering a little longer than usual.

Eva couldn't help but wonder if Jessica had somehow sensed her intentions or if she had just imagined the whole thing.

As they grabbed trays and stood in line for food, Eva could feel the weight of Jessica's gaze. She tried to ignore it, focusing on the food in front of her.

"You know, you don't have to eat so healthy all the time," Jessica commented, pulling a tray of mac and cheese from the warming station. "Sometimes it's okay to indulge a little."

Eva looked at the comfort food piled high on Jessica's tray and then back at her own salad, feelings of inadequacy washing over her.

"I know, I know. But with my workout regimen, I can't afford to slack off too much. Every calorie counts, you know?" she said, trying to keep her voice light.

Jessica raised an eyebrow, her green eyes scanning Eva's tray. "Since when are you so strict? You used to love pizza nights."

Eva shrugged, feeling a blush creep up her cheeks. "Yeah, well, things change. I've got goals now. Plus, it's not like I never indulge. Just... not as much as I used to."

Jessica studied her for a moment before nodding.

"Fair enough. But remember, balance is key. You don't want to burn yourself out."

Eva forced a smile, her mind still racing with thoughts of last night. She could feel the guilt gnawing at her, but there was also an undeniable thrill, an excitement she couldn't shake off.

"So, what's new with you, Jess? Anything interesting happening in your world?" Eva asked, trying to distract herself from her own thoughts.

Jessica hesitated for a moment before answering, "Well, actually, I've been thinking about trying something new."

Eva's ears perked up, her curiosity piqued.

Jessica leaned in slightly, her voice dropping to a conspiratorial whisper. "I've heard about this supplement, GrowYourGirl. It's supposed to help with muscle growth and recovery."

Eva's eyes widened slightly, surprised. "Really? That sounds... intense. I mean, I've heard of stuff like that before, but I never thought you'd be into that kind of thing."

Jessica shrugged, her eyes flicking away from Eva's gaze. "Well, yeah, I know it might seem a bit extreme.

But I figure, why not give it a shot? I mean, I've already tried everything else. Might as well see if this works," Jessica said, her eyes darting back to Eva.

Eva could feel her heart pounding in her chest. She had just ordered the same supplement last night, and now Jessica was talking about trying it as well? Could this be a sign?

"I guess that makes sense. It can't hurt to try, right?" Eva replied, her voice casual despite the racing thoughts in her mind.

Jessica nodded, a small smile playing on her lips. "Exactly. And hey, if it works, maybe we can compare notes.

You know, see how it affects each of us differently." Jessica said, her eyes sparkling with a mix of excitement and apprehension.

Eva's heart skipped a beat. The thought of comparing notes with Jessica sent a rush of excitement through her. She had never imagined that they would have something like this in common, something that could bring them even closer.

"Yeah, that sounds like a great idea," Eva said, her voice barely above a whisper.

They spent the rest of their lunch talking about their respective workout routines and the different supplements they had tried in the past.

Eva found herself relaxing into the conversation, enjoying the easy banter between them. She had always admired Jessica's dedication to fitness, and now she felt a newfound connection with her roommate.

As they finished their lunch and made their way back to their dorm, Eva couldn't shake off the feeling of excitement that had settled in her gut. She had always been drawn to Jessica, but now she felt an even stronger pull towards her. The shared secret of Jessica's tiny dick and the growing fascination with the GrowYourGirl supplement had created a bond between them that Eva had never expected.

Back in their room, Jessica sat down at her desk and pulled out her laptop.

She hesitated for a moment before searching for GrowYourGirl, her fingers tapping nervously on the keyboard. Eva watched her from her bed, her heart pounding in her chest.

"What are you doing?"

Jessica glanced over her shoulder, her green eyes meeting Eva's gaze. "Just looking up that supplement I mentioned earlier. You know, the one we were talking about at lunch."

Eva nodded, sitting up in her bed. "Oh, right. The muscle growth one?"

Jessica turned the laptop screen so that Eva could see it better. "Yeah.

I'm just seeing what the reviews are like, you know? Making sure it's not some scam or anything," Jessica said, her eyes scanning the website.

Eva moved to sit beside her, her shoulder brushing against Jessica's as she read over her roommate's shoulder. "Yeah, that's a good call. You never know what you're going to get with these things."

As they read through the customer testimonials and ingredient lists, Eva couldn't help but notice the subtle changes in Jessica's body. Her muscles seemed more defined, and her breasts appeared fuller, the fabric of her shirt straining slightly against them.

Jessica caught Eva's gaze and grinned. "Pretty cool, huh? I mean, I know the reviews can be a bit biased, but these before-and-after pictures are insane."

Eva nodded, her eyes scanning the images of muscular bodies, their transformation seemingly miraculous. "Wow, it does look impressive. I've never seen anything like this before."

Jessica leaned back in her chair, her eyes flicking to Eva. "I know, right? It's like a dream come true for someone like me.

I mean, I've always wanted to be bigger, stronger. You know?" Jessica's voice was filled with excitement and hope, her eyes reflecting the same.

Eva looked at her roommate, her heart panging with a mix of jealousy and admiration. She couldn't help but think of her own growing body, the way her breasts had become fuller and her muscles more defined in just a short amount of time. She knew she shouldn't be jealous of Jessica, but she couldn't help the green-eyed monster rearing its ugly head.

"Yeah, I can understand that," Eva said, her voice barely above a whisper.

She forced a smile, trying to push down the pang of jealousy she felt. "So, what do you think? Should we go for it?"

Jessica bit her lip, her eyes still scanning the website. "I don't know. It seems too good to be true, you know? I mean, what if there are side effects? Or what if it doesn't work at all?"

Eva reached out, her hand gently covering Jessica's on the keyboard. "Hey, don't worry about that. We'll do plenty of research before we decide. And we'll take it together, so it'll be fine!"

Jessica agreed and both girls ordered the supplement, dreaming of bigger muscles and better workouts.
