After the parents left for the store, stepsister told her stepbrother to grab the collar and leash and fuck her hard in different positions! They only had an hour, but they made the most of it. He started by fucking her mouth with his big thick cock, then pounded her in missionary while pulling the leash, fucked her in reverse cowgirl and regular cowgirl, and finished by covering her face with a thick load of hot cum! The important part was washing her face in time — the parents could come back and start asking questions!
