She figured she'd surprise him too, so reached down and grabbed his cock and then began to lick him clean. As she was doing that, Dave's body tensed, ...and his tongue then dove deeper into her pussy, seeking out the last traces from his orgasm. Dave started pushing the butt plug in and out of Helen’s ass too. He knew how much Helen loved a good ass fucking, so he built up steam on the butt plug and finally was pushing it into her ass in time with his tongue thrusts into her pussy. He was rewarded. He knew I wasn't wearing a bra. I don't want you to go; I want to have fun." She slid her hand down along his hip, then in between their bodies. His zipper came down and her hand was inside. "Besides, if he gets mad, you're young and strong, you can whip his ass. Kiss me, darling."He kissed her, lightly at first, then harder as her hand moved inside his fly, palming his glans, sliding easily back and forth over the sensitive knob. He groaned.Dan stood watching. He could see her hand was between. We went downstairs and sat on her settee. Lucie had a cigarette as the doorbell went. It was Bob at the door. Come in Lucie Said to Bob. Lucie said no need to leave. I put the football on the TV as Lucie and Bob went upstairs but could not concentrate on the game thinking of what was going on upstairs. I could hear Lucie enjoying Bob pleasuring her. And was turned on. If only they let me watch.This carried on for another six months. I would see Lucie, have amazing sex and Lucie would still see. She stroked it with great expectations. She stroked it admirably. She felt it grow. She watched it grow. She watched him too. And as she stroked his beautiful cock in her hand, she saw how unbelievably elated and aroused her son had become all the while she too became hornier then she anticipated. “Oh god mom” he exclaimed enough times to have her smiling from ear to ear as she stroked his cock. It grew and it grew. It got harder and harder. And Kevin became more and more aroused as his mom.
