I had this new roommate move in with me about a week ago. His name’s Alex, he’s 23 like me, and we found each other through some online ad for sharing an apartment. I live in this small two-bedroom place in the city, it’s cheap and close to my job at the coffee shop. When he first came to check it out, I figured I should be upfront, you know? So I told him straight away, “Hey, just so you know, I’m gay.”
He looked at me and then shrugged, “Cool, no issues man. I’ve shared places with all kinds of people before.” That made me relax a bit. He seemed chill, straight guy, works at some warehouse or something, likes sports and video games. We hit it off okay from the start, talking about random stuff like movies and food. It’s been nice having someone around after living alone since my breakup with my ex boyfriend.
Anyway, it’s been a super hot summer. The AC in our apartment sucks, it barely works, and running it all day would cost a fortune in electricity. So we’ve been dealing with it by taking cold showers, keeping windows open at night, and just wearing as little as possible. First couple days after he moved in, we both stuck to shorts and t-shirts, but by day three or four, we were complaining nonstop about the heat. One afternoon, we were sitting in the living room, sweating our asses off. I said something like, “Dude, if you’re too hot, you don’t have to wear all that. Just strip down to your boxers or whatever, I don’t care.”
“Yeah, good idea.” He pulled off his shirt and shorts, left in just his briefs.
Alex is built okay, not like a gym rat, but fit from his job I guess, with some hair on his chest and legs. The thing that caught my eye right away was the bulge in his briefs. Holy shit, it was huge. Like, I’ve seen guys before, hooked up a few times, but this outline was something else. It poked out in front, stretching the fabric a little. I tried not to stare, but my eyes kept drifting back to it. He didn’t seem to notice.
After that day, it became normal. Whenever it got too hot, which was basically all the time, he’d just go down to his briefs around the apartment. I’d do the same sometimes, but I was more self-conscious about it. Gave me plenty of chances to check out that bulge without being obvious. I’d wonder what it looked like underneath. Not in a creepy way at first, just curious. Like, is he really that big, or is it the way the briefs fit? My mind started wandering more after a few days. I’d catch myself thinking about it at night, imagining stuff and yeah, it turned me on a bit. I felt kinda guilty, since he’s straight and my roommate, but hey, I’m gay, it’s natural to notice.
But soon, things started getting interesting. One Tuesday morning, I slept in late. I usually get up around 9 for work, but that day it was closer to 10. My routine is to head straight to the shower. Alex starts work early, like 8, so I figured he’d be gone or in the kitchen by then. The bathroom door was shut, but I didn’t think much of it, just pushed it open. There he was, standing with his back to me, towel over his head drying his hair. He heard the door and turned around quick.
My eyes went straight down. His dick swung around and slapped against his thigh. It was the biggest flaccid cock I’d ever seen, no joke. Thick, long, hanging there between his legs, with some veins and a bit of hair at the base. It settled down after the swing, just dangling. I froze for a second, then blurted out, “Shit, sorry!” and slammed the door shut.
“It’s fine!” he yelled from inside. “Give me a sec!” A moment later, he opened the door, now with the towel wrapped around his waist. He smiled, looking a bit embarrassed too, and said, “Sorry, man. Overslept, running late for work. The bathroom’s all yours.”
The rest of the day at work, I couldn’t stop thinking about it. That size, swinging like that. Confirmed the bulge was real, no padding or anything. And he didn’t freak out, just laughed it off. Made me wonder if he’d noticed me glancing at his briefs before.
Then, next morning, it happened again. I got up a little earlier, still sleepy, headed to the shower. Knocked this time, learning from yesterday. “Just a minute!” he called out. Door opened, and there he was, holding the towel up to his chest with one hand, super loose. It barely covered anything, his pubes were showing, and as he stepped out, the towel shifted, and his dick swung free for a second. I couldn’t help it, my eyes locked on it. He walked right past me, smiling like nothing, said, “Late again, haha.” Didn’t even try to cover up properly. From behind, as he went to his room, I saw it hanging between his legs under his ass cheeks.
