Young Gilf Gives Herself As A Graduation Present ( PART 3 )

I have a stepson named billy. when billy was little, he fell from a tree house in the back yard and the fall messed up his spine pretty bad and as a result of the fall billy walks a bit funny. he is graduating high school this week and i wanted to give him a special treat...as a graduation present. his stepmom kathy and i talked it over. we know that billy's never been with a woman and he's always spying on kathy trying to see her naked. so, we decided that kathy would be that special graduation present. i went into the living room and 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. kathy is a chain smoker and i also know that billy has a smoking fetish because of it. kathy 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. i'm in the room filming the whole thing and i have to say it was a big turn watching my wife make a man out of my step-son. kathy 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 vs120mm cigarette and climbs on top of billy's cock. kathy rides and smokes young billy and really enjoys his young dick in her pussy. 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.
