This happened a few years ago. I had always considered myself straight, but since my teen years I had always enjoyed a little self anal play. In my early twenties had had given online dating a shot hoping to find a woman that would be into pegging me. Self play was fun but I was really starting to crave just being a bottom for someone. I didn't want to have to reach around and fuck myself with my dildo any more, I wanted someone else to take control, someone else to set the pace, someone else to hold my head down and trust into my and transform me into their butt slut.

However it turns out it's not so easy to find someone who is that into pegging. Despite the endless supply of wonderfully kinky people on Reddit, my local dating scene wasn't too keen on the role reversal, so I took some more drastic measures. After a few weeks of trying I found a guy not too far from me who was looking for a casual hookup. We exchanged some pics, texted a bit, and about an hour after I first messaged him, I was ringing the buzzer at his apartment.

We greeted each other but he quickly made it clear he wasn't interested in any pleasantries. I removed his clothes to reveal his hard cock. The pictures this guy sent did not do him justice, he was hung, and my nerves went from 10/10 to 15/10. But there was no backing down. As quickly as his sweatpants hit the floor, so did my knees. He let me take his cock in my mouth at my own pace at first. I was afraid of taking too much at first and gagging so I just wrapped my lips around his head. I locked the bottom of his dickhead while I tried to work up as much saliva to lube him up as I could for what I knew was coming. But he soon became inpatient and started taking control. At first he slowly thrusted into me, pushing his dick about half way in across the top of my tongue . But then he grabbed my head with both hands and started forcing himself all the way down my throat. By the time my noes was against his pelvis I was gagging and gasping for air. I tried to push his thighs back but he held me in place a few extra seconds before letting me come up to catch some air. He repeated this balls deep throat fucking a few times, and just before I was about to call mercy and tap out, he stopped and pointed me towards the couch.

Without exchanging any words I removed my pants and took the position, knees on the ground, bent over the front of the couch. He gave my big ass a few unexpected spankings and then mounted up behind me. I could feel his hard cock press against my hungry ass but I knew it was going to be too big. Even my biggest toy paled in comparison. He was ready though. He pulled out some lube and lathered he and I up real good with it. And the second attempt to penetrate me met no resistance. He stretched me wider than I've ever been stretched but he slid right into me. He pushed himself in balls deep and held himself there for a pause. Then he spoke the only words he would say our entire encounter: "fuck, you're tight." And from that moment I was no longer straight.

The way he said that was so lustful, so selfish in his expression of pleasure, I was forever changed. I wasn't here just to get my prostate tickled any more, I was here for his pleasure, and he took everything he could from me. He started thrusting into me over and over again. Every time I thought he had gotten all the way in he somehow pressed in deeper. I completely lost track of time in this ecstasy. I didn't move, I didn't speak, I could barely even think. I was just the tight warm hole this stranger was using for his own pleasure. I tried to push back into him but there was no more to take, he had his hands around my hips and was plowing away slow and steady. He pulled out a few times to rest but I dared not move.

After about an hour (more stamina than I thought humanly possible) I felt his presence change and prepared myself for him to finish. As soon as I realized what was happening I tried to tell him to pull out, but my voice was lost, and it was too late anyways. He thrust deep inside me one last time and I could feel his warm cum fill me up. After he finished and caught his breath he finally pulled out. He got up ever silent and handed me my pants. I took the hint, quickly dressed and was out the door. I could feel his cum dripping down my leg the entire drive home, but all I could think was: when can I do this again. I was forever changed into the bi butt slut I am today.
