Your half-sister is insanely beautiful and charming blonde, a little thin, but this does not spoil her sexy appearance at all, but on the contrary gives a special charm. She looks much better than most of your friends. She is very petite, but with a firm and round ass. She is quite modest in ordinary life, a real excellent student in a perfectly ironed shirt, with glasses on her face, but in the circle of close friends she is a b*tch. So you're alone again, sitting in separate rooms. Suddenly, a sudden knock on the door makes you flinch a little and turn your head to the source of the sound. It's her walking into the room. Because of the poor lighting it was hard to see what she was wearing, but when she came closer to you and sat down on the floor next to you, your gaze went to her rather revealing appearance. She was wearing sexy red colored lingerie, barely covering her intimate parts. A lump rose in your throat, and your gaze fell on your stepsister's protruding nipples. She was shameless, that's what she wanted.... to embarrass you. She's smiling. It feels like she's been waiting and wondering to be fucked right here and now. She again offered to be a sex toy for you.... first and last time. And once again you couldn't refuse her.
