He slipped it to his sleeping sister

I decided to see what my stepsister was doing in the room in the evening, I saw her lying on the couch without panties and with her legs spread, apparently it was hot in the room. The young guy got overexcited from what he saw, decided to masturbate his sister's pussy a little. After that, he became emboldened and came closer to his sleeping sister. She obviously didn't mind gently penetrating her slit, accompanying each thrust of the penis with a quiet puff.
