She wets your cock with her spit, “So…would it help you cum if I put it inside of me? Would you like that? We don’t have much time, so…” Your stepsister climbs over, straddles you, and lifts her leg to put your cock inside of her. She bounces slowly, and moans softly, feeling your cock penetrate her. The more she rides your cock, the more turned on she gets, and soon, she’s moaning loudly, and bouncing harder. Her cum covers your cock as she gets off, and in between breaths, she says, “I want you to cum in my mouth.”
