BBW smoking MILF fucks her handicapped stepson

Billy is graduating college this week and I wanted to give him a special treat...as a graduation present, his stepmom Kathy. We know that Billy's never been with a woman and he's always looking on Kathy trying to see her naked. I asked Billy top come to the guest bedroom. When he opens the door, he sees Kathy standing there topless and in a sexy white girdle. She takes his shirt off and pulls him to her breasts. Billy just dives in sucking her nipples. Kathy goes over by the window and teases him by slowly taking off her girdle as he strokes his hard cock. She starts to suck his cock like an expert and Billy is rock hard in seconds. Kathy puts some of her special oil on Billy's cock and strokes him up and down with her hand. Kathy lights up another cigarette and climbs on top of Billy's cock. They fuck in many ways until Billy can't hold back any longer. With Billy on top, Kathy jacks him off all over her face and mouth.
