Step sister interrupts my playtime to flaunt her big, curvy buttocks, leaving me with the choice of getting fucked or continuing to play

I was chilling in my dorm room, enjoying a steamy game of self-pleasure, when my step sister barged in, interrupting my flow. She had the audacity to flaunt her massive, curvy buttocks, leaving me with a choice - continue my solo act or get down and dirty with her. As a horny 18-year-old, I was more than ready to engage in some wild action. After some back and forth, we settled on a steamy game of roleplay, with her taking the reins as the dominant force. With her petite frame and irresistible charm, she rode me like a true pro, skillfully taking control and driving me wild. The intensity built up, and I couldn't resist the urge to cum. As I reached my climax, she took it all in, reveling in the warm, sticky aftermath. This wasn't just a quickie; it was a mind-blowing experience that left us both satisfied and yearning for more.
