B/G Couch Sex in Garter Stockings

I call to invite my boyfriend over because my mom and step dad are leaving the house for the night and I'm SO horny. I tell him that I will leave the door open and I'll be waiting in the bedroom with his favourite outfit on (red 3 piece lingerie, black thigh high stockings, black collar with chain leash). I strip tease and change into the outfit while dirty talking. Waiting for my bf on the bed, MY STED DAD WALKS IN! He is shocked by what I'm wearing and that I have my mom's collar on! My step dad wants to punish me for inviting a boy over and I want him to! POV Boy/Girl sex in missionary and doggy, close ups, spanking, choking, hair pulling, taboo dirty talking, messy creampie.
