I have sex with my reserved stepsister vigorously and demonstrate to her that I am not homosexual. Ultimately, I ejaculate on her buttocks.

I've been walking around the house for hours, trying to find something to do to get my mind off of you. I've been thinking about you constantly, and I can't believe I've never been attracted to you before. Your big, natural tits are driving me crazy, and I just can't resist them. I've been dreaming about having sex with you for weeks, and I finally decided to take action. I pushed you up against the wall, and I started to undress you. I was surprised by how reserved you were, but I knew I had to show you that I'm not homosexual. I took off my clothes and revealed my big cock, and I started to fuck you hard. You moaned in pleasure as I pounded your big pussy, and I could feel your tightness around me. I pulled out and ejaculated all over your big, juicy ass.
