Unexpected intimacy with my young step-sister in the dorm

I'd been looking forward to a peaceful day in my dorm room, but fate had other plans. My young step-sister, all of 19, dropped by for a visit, and things took an unexpected turn. As we chatted, the heat between us grew, and before I knew it, she was on her knees, her lips wrapped around my throbbing need. The sight of her tiny hands on my massive manhood was a sight to behold. But the real surprise came when she let me fill her up, her tight little hole taking every inch of my length. The sight of her, her body writhing in pleasure, was enough to drive any man wild. And as I filled her up again and again, I couldn't help but think of all the other ways I could explore this young, eager girl. She may be young, but she's got a big appetite for the kind of action that only a mature man can provide.
