My buddy Riley and I, Alex, both 18 years old, are total fitness freaks. We hit the gym three to four times a week, pumping iron to bulk up our muscles. But honestly, it wasn’t really working out for us, and that’s probably why we’re both still single. It was getting pretty depressing until one day, a guy at the gym came up to us and slipped us a website link. He said we could order some cheap “vitamin pills” there. We knew stuff like that isn’t exactly legal in Germany, but curiosity got the better of us, so we checked out this Chinese website. It was packed with all kinds of products—everything in Chinese, of course, but that’s what Google Translate is for, right?


After digging through the site, Riley and I figured out which supplements might work for us. We were on the same page: let’s order this stuff, and in a few weeks, we’ll look like Arnie—Arnold Schwarzenegger! It took ages to navigate the site, but finally, I ordered a big pack of pills, while Riley, who had a bit more cash, got a different set—pills plus some injections. Four weeks later, we got these plain-looking packages, and our orders arrived safe and sound. The instructions were, of course, in Chinese again, but we figured it couldn’t hurt to take a few doses of our muscle supplements every day.

We’d ordered bulk packs, and after four weeks, I started noticing changes. I was gaining muscle mass nicely, and my dick still worked fine—not that I had a girlfriend to test it with. My right hand was still my only “partner.” But Riley? Things weren’t going as planned for them. Sure, they were changing too, but not in the way we’d hoped. Plus, Riley was getting super moody, almost girly. Their interests started drifting away from mine—less about training hard and more… different. We still kept in touch, but we hung out way less. That is, until carnival season rolled around on February 1, 2025, and I got two free tickets to a party in Cologne. It was a costume-required event, and even though Riley had been keeping their distance, I wanted to do something fun together. So I gave them a call. “Yo, dude! I got two tickets for a carnival party. Wanna come? We can get some girls drunk and hook up—it’s always a vibe at these things. Only catch is, you gotta wear a costume. You in?”

It was quiet for a couple of seconds, just Riley breathing on the other end, before they finally said yes. That night, we met up at the entrance to the venue. I barely recognized them at first. I went as a pilot, my usual go-to costume, and I figured Riley would show up as a soldier—their standard pick. But standing in front of me was a gorgeous young woman. It was Riley, dressed up as a girl! Had they lost it? This wasn’t some trans girls’ party. How were they supposed to pick up chicks like this? Well, I guess that’s one less guy to compete with. Still, I had to give them props for the costume. In a black mini dress, a long black wig, black nylon stockings, and high-heeled pumps, all perfectly styled, Riley could’ve given any girl a run for her money.

We grabbed a table, and I ordered my usual Kölsch beer, but Riley? They went for a Prosecco. “Come on, don’t overdo it, dude. People are gonna think you’ve actually got a pussy down there,” I teased. I’d noticed their chest—small boobs, probably fake ones from a sex shop. Then they hit the dance floor, acting all girly, dancing close with guys and even flirting with other women. I started feeling second-hand embarrassment. My best friend was acting like a trans girl—or more like a woman, really. The night dragged on, and once again, I struck out with the ladies. I was feeling pretty down. Riley, though? They scored a bunch of phone numbers—all from guys! After getting pretty wasted on Kölsch, we stumbled back to my place, just like we used to.

We plopped down on my couch and started streaming some movies. I sat with my legs spread wide—my dick needed some space in my pants, you know? But Riley curled up on the sofa, legs tucked under, looking bored while I put on an action flick. I must’ve had too much to drink because I dozed off pretty quick. Then I woke up in the wildest way. I don’t know if I was supposed to wake up, but someone was sucking my dick, and I was about to cum. I looked down and saw Riley’s black wig. This freak was sucking me off! Normally, I’d have jumped away, but the booze and the fact that I was so close to cumming stopped me. At that point, I didn’t care. First, I hadn’t managed to hook up with any chick at the party.

Second, it was just the two of us. And third, no one had ever blown me as good as Riley was doing right then. They were sucking my cock so passionately, their head bobbing up and down with wet, slurping sounds. Then my cum shot out of my balls, straight through my dick, right into their mouth. Riley didn’t even flinch as I unloaded down their throat, greedily sucking until every last drop was on their tongue. They even gently licked my tip clean afterward. Holy shit, that was insane.

Riley lifted their head, wiped a bit of cum off their lips with a finger, and sucked it clean. Girls usually spit it out right away, but Riley swallowed it all. They sat back on the other end of the couch, looking down, clearly embarrassed. “Yo, what’s up with you? Since when do you suck dick?” I asked. “I don’t know what’s going on with me,” Riley admitted. “For weeks now, I’ve been feeling like this. I’m into guys, and I feel like a woman. Tonight was the first time I went out as a girl, and it felt so good.” “Have you changed that much?” “Yeah, totally. My skin’s softer now, I don’t need to shave anymore, I’ve grown little boobs, my dick’s shrunk, and the hair on my chest is gone. Everything’s different.” “Holy crap, I think you got the wrong stuff from that Chinese site.” Riley just shrugged. We tried checking the website again, but it was shut down—gone. “You gotta stop taking that stuff,” I said. “I’ve tried, but I can’t. It’s like I’m addicted! I can’t stop.” “So what now?” “I don’t know.

The pack’s almost done. I just need to finish with a pink pill and an injection, then it should be over.” We sat there in silence, Riley’s eyes welling up with tears. I felt bad for them. “Why are you crying? Because you turned into a trans girl?” “No, not at all. I’m ashamed because I jumped you like that, and you didn’t like it.” “Nah, it was hot. You’ve done that before, huh?” “No, I swear, that was my first time. You were just lying there, looking so good, and I couldn’t help it. I just wanted to see your dick, then touch it, and before I knew it, I had it in my mouth.” “We’ll translate your instructions word for word tomorrow. And by the way, you give amazing head!” Riley laughed. “And you’ve got the perfect cock and a ton of cum.” We crashed—Riley on the couch, me in my bed. I couldn’t stop thinking about what happened. It was hot, no doubt.

The next morning, around 11 AM, I woke up to noises in the kitchen, my head pounding and my balls feeling heavy. I dragged myself out of bed and couldn’t believe my eyes. Riley was in the kitchen, wearing just a red satin thong and matching bra, cooking scrambled eggs. Their body had changed so much—their waist was slimmer, shoulders delicate, and their ass? It was round and looked damn firm. My dick got hard instantly, but alarm bells went off in my head. *This isn’t right. They’re a guy. They’ve got a dick. This isn’t natural.* Riley turned and smiled at me—not a guy’s smile, but a feminine one. My best friend had truly transformed into a woman in both looks and behavior.

Their boobs filled out the bra completely. The only thing holding me back was the slight bulge in their panties—not much, barely noticeable, but still there. Riley glanced at my shorts, where my hard-on was obvious, a big bulge tenting the fabric. I could see the desire in their eyes—*I want that cock!*—but they held back too. “Morning! Sleep well? Thought I’d make us some breakfast,” Riley said in a seductive tone. We sat down, ate, and drank strong coffee.

The whole time, I couldn’t stop staring at their new body. If they were a real girl, they’d be a total 10, winning any beauty contest hands down. My dick stayed hard the entire time. “What do we do now?” I asked. “I thought about it last night,” Riley said. “I wanna stay like this. I don’t care what people think—I feel good. My only worry is that you’ll end our friendship. We’ve known each other since kindergarten.

That’d break my heart.” There was a mix of sadness and hope in their voice, and I felt for them. I mean, I’m the one who convinced them to order from that Chinese site in the first place. “Of course we’ll stay buds. We just gotta figure out what that looks like now. You’re… different.” Riley’s face showed both joy and a hint of sadness. They got up to clear the table, their legs long and smooth, not a hair in sight. *Are their feet smaller now?* “But we’re not gonna be a couple, and no more blowjobs. Just best friends,” I said, even though my hard-on was screaming otherwise. “If that’s what you want, then that’s how it’ll be,” Riley replied, their eyes lingering on my bulge with a hungry look.

While clearing the table, Riley played up their femininity, bending over to give me a perfect view of their boobs—damn, they looked amazing. They wiggled their ass too, and I had to fight the urge to grab it. I got up to grab a bottle of water for my hangover, “accidentally” brushing my dick against their ass as I reached for a glass. *Mmm, that feels good.* I wanted more. Riley was washing dishes, and I reached over them to grab a glass—even though I usually drink straight from the bottle—just so I could brush my dick against their ass again. Riley pushed their butt out further, practically inviting me. I must’ve brushed against them too many times because after a deep breath, Riley turned and said, “Sure we’re just friends?” That snapped me back to reality, but then they gently stroked my dick. “No one has to know—this can be our little secret.” Their fingertips teased my tip, and it felt so good.

“Hi, I’m… uh… Riley, and I want your cock,” they moaned, their voice feminine now. It was too late to say no. I let Riley stroke my dick, giving me a slow, gentle handjob. “You like that, huh?” they teased. Hell yeah, I did—so much that I pushed their bra up, and two perky boobs popped out. Damn! When was the last time I’d seen tits like that? I grabbed them, warm and soft, and my dick got even harder. Riley started sucking on my nipples—something no girl had ever done to me—and it turned me on even more. They pulled my shorts all the way down, now jerking me off while massaging my balls like a pro. I wanted to do the same to them, but they pushed my hand away. Then something weird happened again—Riley kissed me on the lips. I didn’t know how to react at first. Even though they looked so feminine, it was still my best friend’s face. But when I felt their soft lips on mine, I forgot all my doubts and kissed them back.

Our kisses deepened, my tongue brushing their lips first, and Riley eagerly reciprocated, turning it into a passionate, erotic make-out session. It only stopped when Riley started kissing down my body—my neck, my hard nipples again, then lower until they were squatting in front of my cock. They kissed my shaft hungrily, even my balls, licking up to my tip and teasing the slit with their tongue. What I’d only half-experienced last night while drunk, I now felt fully awake.

No girl had ever pleasured me orally this well. When Riley took my sensitive tip into their mouth and sucked, I didn’t dare touch them, afraid they’d stop. But they paused, looked up, and asked, “You liking this?” I just nodded, my legs shaking as I tried not to collapse. Riley went back to sucking, their cheeks hollowing out, their head moving faster. I groaned loudly, but their moans and slurps were even louder, like my dick was their heaven. I felt my cum building, wave after wave. “I’m gonna cum!” “Not yet!” Riley stopped, blew cold air on my tip, and managed to delay my orgasm just in time.

“You’re driving me crazy,” I panted. “Oh, really? Didn’t you say we’re just friends?” Riley smirked, teasing me. They had me—literally—in the palm of their hand, stroking me slowly while I stood still. We kissed again, our tongues tangling, and I threw all my reservations out the window. All I wanted was to cum for them. Then I noticed Riley sliding their panties down. They took my hand, guiding it to their belly button, then lower. I got nervous—I didn’t look, my eyes closed as we kissed—but I knew where they were leading me. Then I felt it. It wasn’t like a girl’s pussy, but a piece of flesh. Not much, pretty small, and soft. I brushed the back of my hand over their dick—it was a bit thicker than flaccid, but not hard. Riley took a deep breath, so it wasn’t completely dead down there, just not fully functional anymore. Meanwhile, my cock was standing straight up, loving Riley’s handjob. Without thinking, I started stroking their little dick. It thickened a bit but stayed soft.

Riley jerked me off harder now, and I felt the pressure in my balls building. I hoped they wouldn’t stop again—I couldn’t handle that kind of torture. I kneaded their boobs with one hand, stroking their little dick with the other. “I’m gonna cum! I need to cum! I don’t care where!” “Yes, cum on me! Cover me! I wanna feel your cum!” Riley sped up, gripping me hard, their hand moving fast like only a guy would know how. They didn’t stop as I came—I felt my cum surge through my shaft and shoot out, splattering onto their body, right onto their little dick. Good thing I’d pulled my hand away, grabbing their firm ass cheeks instead. Riley moaned almost louder than I did, loving the feel of my cum on them, even though they didn’t cum themselves. They milked every last drop from my balls, better than any girl ever had, then slowed down, rubbing my tip with the remaining cum, even pressing it against their stomach to wipe me clean.

Their soft little dick was covered in my cum, slowly dripping down. Riley looked so happy—and so did I. But then it hit us, what we’d done. Neither of us could fully process our feelings. We’d been best friends since we were kids—learned to ride bikes together, went to school together, even played on the same soccer team. And now? We’re having sex because Riley transformed into a trans girl. I looked at them, confused, but Riley just smiled back. There was nothing left of the guy I knew in their eyes—just a new, different kind of friend. I went to shower while Riley casually used the bathroom, sitting down to pee like a girl. Typical. We spent the rest of the morning and afternoon mostly in silence, neither of us finding the right words. Riley cooked lunch for us, occasionally giving me a little kiss or a gentle touch. We sat on the couch together, but neither of us started a conversation about our future.

Late that afternoon, I decided to lie down for an hour. I’d barely gotten into bed when Riley joined me. “Can I lie with you? I promise I won’t do anything—I’ll leave you alone,” they said. I nodded, a bit grumpy, like a reluctant boyfriend or husband. But as Riley stripped down to their panties and climbed in beside me, I felt that familiar warmth, and my dick started to stir again, just from looking at their boobs. Riley leaned in for a kiss, but I wanted more. We shared a deep, passionate tongue kiss, their hand sliding from my chest down to the waistband of my shorts. They teased my dick with their fingertips for a moment before pulling away and turning over. They’d promised not to do anything, and they stuck to it. Great—how am I supposed to sleep with a hard-on when someone who could help is lying right next to me? I pressed closer to their back, my hard dick brushing against their ass.
