Mark sneaks into Renata's room and takes a pair of her panties out of the drawer. He sniffs them and then puts them on, just as Renata and Natali walk in. Renata is furious that he is wearing her panties but decides if he wants to wear girls clothes he should do it properly and she gets a miniskirt out of her drawer and makes him put it on. Natali laughs her head off at this but Renata hasn't finished and fetches two strap-ons which the girls put on. They then bend Mark over on the bed and tell him they are going to treat him like a girl and fuck him. Renata goes first and fucks his ass while Natali laughs at his very loud discomfort before shoving her strap-on in his mouth to shut him up. The girls then flip him onto his back and Natali has her turn fucking their new bitch's asshole. Renata undoes her top and lets Mark suck on her tits while he strokes his cock and he is soon cumming all over himself, with Natali's strap-on still firmly inside his asshole!
