I had thought my stepsister was a very serious, reserved, and quiet person. But then I saw her bringing a man home to give him head. From that day on, I started looking at my stepsister with sexual intent! Watching her eat ice cream made me imagine her blowjob face and get excited. Before I knew it, I had replaced the ice cream with my dick in her mouth and made her deepthroat me! It felt so good that I came right then and there! Thinking it was bad, I immediately apologized, but instead of getting angry, my stepsister said, 'Do it even harder' and demanded more. She was such a slut!
