We're roommates and you come home when I wasn't expecting you. When you walk in I'm wearing your girlfriend's clothes. I'm embarrassed and act flustered at first, but you tell me I look pretty in her outfit. I'm flattered and you suggest that I would look cuter locked in chastity. I convince you to roleplay as your girlfriend and you tell me to call you step-daddy like she does. I start groping your thick cock in your pants and then get on my knees and suck your while I gag on it and roleplay with you and praise you! I then let you fuck my ass because your girlfriend never lets you do anal. You make me cum and leak out in my chastity cage before coming in my ass! I push out your creampie and thank you for cheating on your girlfriend with me~
