I come in to say goodnight and i notice your girlfriend is already asl eep. It's just me and you all alone. I start to rub you and caress you and get you horny. I tell you im gonna straddle your face and ride you. All while your GF is asle ep next to us. We try to be as quite as we can be. It turns us on so much the thrill of her catching us is so hot. You get on top and fuck me till your cum oozes out of step-mommys' pussy.
