Stepmom Wants to Pee on Your Cock

You’re my stepson home from college for the weekend and you walk in on me your stepmom showering. We’ve hooked up several times before because your stepdad just can’t satisfy me and you and I both have a piss/pee fetish. I offer to back up on your cock and pee all over it before your step-stepdad gets home and you happily agree.
