Movie description: "A Cheeky Exercise". For a while now, Christie's yoga instructor has been scolding her for not getting the positions right. He always tells her that her body is very tense and her muscles are very rigid and that this way she will never be able to relax. Robbie, Christie's stepson, tells her that his girlfriend had a similar problem until he helped her with a special relaxation technique: anal sex. Committed to helping his stepmom, Robby takes her to the room, pulls out his cock, and slowly pushes it inside Christie’s asshole. As it gets in, the milf feels how her muscles start to relax, opening up her ass real wide for her stepson to get it all in. Tension relief soon becomes pleasure, and Christie’s ass is jumping on Robby’s cock, feeling that meaty dick relax every inch of her body.
