Her AB boy gets a stiffy while being breast fed - again. His mommy is disgusted or at least pretends to be. Lillian gives him a good spank over his diaper. She feels inside it and he is still hard so she takes off his diapee for a good hard OTK spank on his bare bum. Now his diaper is off and is willy exposed she starts to tease him. She strokes his pee pee up and down to keep him aroused but then spanks him again and again because he does not lose his rock had stiffy. How could he lose it when she teases it like that?
