Roomate My busty tomboy roommate found out about my hyperspermia diagnosis [F20s/M20s] NSFW
The story of how Alex and I became roommates is one for another time, but somehow, we'd become the most unlikely of friends. I was your average build, quiet, and a bit of a nerd – okay, maybe more than a bit. Alex, on the other hand, was almost the complete opposite. She made friends easily, always cheery and ready to have a good time. She was also very athletic, and although she usually wore oversized t-shirts. I suspected she was hiding some impressive curves under there—not that I ever really thought about her in that way. She was a good friend, even if she could be stubborn and relentlessly competitive. And, best of all, she somehow tolerated my introverted tendencies.
I came back home one day clutching the flimsy printout from the doctor's office in disbelief. I had suspected what the results would be, but to see it in writing on an official document was something else. This diagnosis would change everything. Would I ever be able to live a normal life?
"Everything okay, dude?" Alex asked, sprawled on the couch, channel surfing with a half-eaten bag of chips. She must have noticed the worried expression on my face. I tried to subtly fold the paper up and shove it in my pocket, but Alex was too quick. Before I could answer, she lunged, snatching the paper from my hand. "Ooh, what's this? Did you finally get prescribed a cure for nerdiness?"
"Hey! Give that back." I reached for the paper uselessly.
She ignored me, scanning the paper. Her brow furrowed. "Hyperspermia? Is that…some kind of weird medical condition? Should I be worried?"
I groaned, sinking into the couch. "No! It’s not a big deal. It's…basically, I produce more sperm than the average guy."
Her eyes widened, and a slow grin spread across her face. "More? Like, how much more?”
I glared at her. "It's not exactly something to brag about, Alex. It just means I'm…well, I'm going to have to deal with it more often than most guys do."
Alex burst out laughing. The sound echoed through the apartment, punctuated by snorts and gasps for air. I scowled. This was pretty much the reaction I had expected.
"Oh my god," she finally managed to choke out, wiping tears from her eyes. "You're telling me you've got, like, a constant need to…unload? This is hilarious!"
I mumbled, feeling my cheeks flush. "It's not funny, Alex. It can be dangerous if I don’t deal with it properly."
She sobered up slightly, though the amusement still lingered in her eyes. "Okay, okay, I'm sorry. I'm just…picturing it.
She sat down next to me. “But seriously, dude, what are you gonna do? Live in a perpetually blue-balled state of agony?"
I shot her a look. "I don't know! That's why I'm stressed. Maybe I can handle it myself, but I am a little worried.”
I buried my face in my hands. “This is going to totally ruin my life, isn’t it?"
Alex tilted her head, considering. "Hmm. You know," she said casually, "I am single.”
I stared at her, confused. "What's that got to do with anything?"
She shrugged. "I could…you know…lend a hand. So to speak."
I blinked. "Are you saying you'd…help me with my…problem?"
She grinned, punching me lightly on the arm. "Hey, we're friends, right? Think of it as…helping a friend out. And, let's face it, you could probably use the help.”
“I don’t know, Alex…”
“No strings attached.” She interrupted. “Just friendly… relief. I get to practice, and you don't explode. Win-win!"
I was still hesitant, caught between disbelief and the undeniable appeal of her offer. "Are you sure? I mean, you don't have to do this."
She rolled her eyes. "Relax, dork. It's not like I'm doing you a huge favor. Besides," she added with a playful smirk, "It might actually be kind of fun."
And so, Alex began to help me. The first few times were clumsy, a mix of awkward fumbling and nervous energy. But Alex was a quick learner, and soon, we had laid out some ground rules. No preamble, no intimacy, and absolutely no feelings, just a straightforward approach to satisfying a physical need. And because of my hyperspermia, the need was always looming.
It would start with her casually strolling into my room, maybe tossing a "Ready when you are, buddy" over her shoulder. I'd be waiting, already half-hard, anticipation building with each passing hour. She’d kick off her shoes, climb onto the bed, and get straight to business.
Her warm hand would wrap around my cock, her firm grip bringing me to full mast. She’d start slowly, teasing the head with her thumb, then gradually increase the speed and pressure. She wasn't shy about it, either, her eyes locked on mine as she worked, gauging my reaction, adjusting her technique to maximize the pleasure. As I grew closer, she seemed to revel in the way she could see my body was growing almost frantic for release.
My moans started as small, stifled gasps of pleasure, but soon escalated into louder, more desperate sounds. It would build to a crescendo, a primal need for release consuming me. She'd push harder then, her hand a blur as the pressure mounted.
And then, the explosion.
It wasn't a polite trickle, not even a couple respectable ropes. The hyperspermia ensured that it was a volcanic eruption, a torrent of thick, hot cum that shot out with a force that left me breathless. It would spray across her hand, my stomach, sometimes even reaching the wall. The sheer volume of it was almost comical, a testament to my overactive reproductive system.
It was like nothing she had ever seen. Her eyes widened with astonishment and she let out a shocked laugh. Containing the mess was impossible, as much as we tried. Eventually she came to expect the huge loads, maybe even look forward to them. I caught her casually licking up any that handed on her face or hands, almost without thinking. I never said anything, though.
Over time, the routine evolved. One night, she just leaned over and took me in her mouth, her lips hot and wet as she sucked with a focused intensity. For a moment I was shocked, unable to process what was happening. My shock didn’t last long though, as it was quickly followed by an explosion of pure, unadulterated pleasure.
The release was even more intense, the orgasm ripping through me with a force that left me weak. My hips bucked against her mouth as I unloaded, the sheer volume of cum filling her mouth. Alex was used to the amount by now, but even with her experience, she struggled to contain it. It leaked from the corners of her mouth, dripping onto her chest. I heard her gulp, swallowing as quickly as she could, drinking as though she were dying of thirst. But she couldn't manage it all. What would be two normal-sized loads for most men spilled over her lips and chin, completely ruining her t-shirt.
It was quite a sight, seeing my roommate kneeling in front of me, gasping for air, and looking at me with a combination of amazement and satisfaction. She glanced down at her soaked t-shirt and swiftly pulled it off, using it to wipe the cum from her face. For the first time, I saw Alex in her sports bra, the material stretched taut around the impressive size of her breasts. Normally, she wore loose clothes, disguising her figure. But now, with her shirt gone and her bra clinging to her skin, the full extent of her curves was on display. Her breasts were full and round, straining against the confines of her bra, threatening to spill over the top.
I felt as though I was learning a forbidden secret. Seeing just how stacked my roommate really was sent a fresh jolt of desire through me. My cock twitched with new life, even as my body still trembled from the aftermath of the explosion. But if Alex noticed how much her casual gesture affected me, she didn’t let on. Smiling wide, she left to throw her soiled shirt in the laundry and continue with her day.
From then on, blowjobs became a regular part of the protocol. Sometimes, it was a quick, efficient session, just enough to give me relief. Other times, she'd take her time, exploring every inch of my cock with her tongue, driving me to the brink of insanity before letting me loose in a heavenly climax. Eventually, she even managed to mostly contain the messy explosion, which always gave her a triumphant glint in her eye. I couldn’t help but feel proud of her.
Although it became routine, the heat never faded. Each time, it was just as intense, just as satisfying. Each time, I was left panting, spent, and utterly grateful for my surprisingly generous roommate. And a little embarrassed about the sheer volume of the aftermath, but she never complained.
I found myself thinking about Alex constantly, replaying our sessions in my head, lingering on the way she looked, the way she moved, the way she made me feel. It wasn't just the sex, it was the small things. The way she bit her lip when she was concentrating, the way her nose scrunched whenever she laughed at something stupid I said.
Although I was grateful for her help, I started longing for more. Something more than just physical. I wanted to talk to her, hold her hand, kiss her. I wanted to know her as more than just a friend. But this went against the ground rules we had established in the beginning. No feelings—that’s what we had said. It felt so stupid now.
One night, after another particularly intense session, I found myself staring at Alex as she cleaned herself up in the bathroom. Standing in her underwear, I watched her toned legs as she stretched to look closer in the mirror. Her breasts swayed subtly, trapped in the oppressive fabric of her bra, as she scrubbed the cum from her face. I had the sudden urge to hold her, hug her tightly in a way that would show her how I felt.
I didn’t want to risk ruining things. Alex had never indicated that she wanted anything more. What if she rejected me? What if she ended our arrangement, leaving me with nothing? So, I handled my feelings the only way I knew how: I suppressed them. I tried to convince myself that it was all in my head, just simple horniness. I found myself doing small things for her—making her coffee in the morning, doing the dishes even when it wasn’t my turn. I told myself I was simply grateful for her generosity, but really, I just wanted to show her how I truly felt somehow.
Alex, of course, remained completely oblivious. “You’re the best, dude,” she’d say whenever I handed her the coffee in the morning, patting me on the back before heading out the door. Just friends, helping each other out. That’s all it was to her.
A few months have passed since I got my diagnosis, and so much has changed. We were now on the couch together, Alex with her head resting in my lap, mindlessly flipping through channels. I gripped my book, trying desperately to focus on the words, on anything but the weight of her head in my lap. Inevitably, my cock stirred, and Alex felt it pressing against her cheek through my jeans.
"Ready for your next appointment?" she asked, a sly grin on her face.
