Ethan, home alone with his naughty stepsister Kait, finds her sprawled on the couch, fingers buried deep in her pussy, moaning. He joins her, stripping off his clothes to reveal his massive, throbbing cock. Kait, hungry for it, straddles him, impaling herself on his length, riding him hard while Ethan grabs her bouncing tits, lost in the taboo pleasure of their familial fuck fest.
