Your step-sister is crashing with you, in trade she takes care of the house. An arrangement she was happy with until she realized the deal was basically leaving her an unfucked wife. Something you are all to willing to fix. She’s reluctant at first. She was mostly joking, fucking your sibling is something you SHOULDN’T EVER DO… right? She gives in, it just feels too good but you don’t get to finish in her. That’s something she’s saving for the man she ACUTALLY marries. She hops on top and rides you to a second orgasm. You couldn’t help but cum when you feel her tighten around your cock… or could you? Who would be a better wife then your step-sister after all?
