I take my little stepsister's shirt off to see her tits and come on top of them.

My shy stepsister usually wears my clothes, she has the habit of always wearing my best shirts, I look for her in the room and surprise her with my favorite shirt, I ask her why am I going out with my girlfriend and she likes that one, I ask her and I take it off, when I take it off I discover her beautiful tits and that makes me horny and makes me fuck her hard.
