He transformed my butt into a vagina with his massive shaft

I've always been a bit of a bisexual, and there's nothing I love more than a good ass worshiping session. But when my friend showed up with his monster cock, things took a wild turn. He had this crazy idea to turn my butt into a vagina and fuck me like a girl. I was initially hesitant, but the sight of his huge dick made me weak in the knees. He started by spreading my asshole wide and then pushed his fat cock inside, stretching me to the limit. The sensation was unlike anything I've ever experienced before. His big cock filled me up, stretching my ass in the most erotic way possible. The anal sex was intense, but I loved every second of it. His monster cock fucked me hard, turning my butt into a vagina, fulfilling his wildest fantasy. It was a night I'll never forget.
