She knew she should say something, or stop them, or leave. She shifted slightly to allow her legs to open. Her pussy was pulsing as she watched what h...r nineteen year old virgin daughter was doing with Dave. She wet her lips as her mouth went dry. She tried to leave but slumped back to watch. She couldn’t take her eyes off them. Dave`s hands opened Mandy’s string bra. Her tits to sprang out, causing Carol to gasp at the way the nipples stood out as they hardened. Her own nipples were starting.

She repeated the movement again. And again. She grinned to herself as she began steadily sucking his dick. Rebecca simply watched with trembling excitement as Rachel. And kinds smirks. Sarah that's fine by me and smacks him on the ass and walks back to the room. As she leaves she stops and turns to my wife and says "hes all yours." Sara turns back and continues to the living room.

I glance out at my wife who is starring at me as Dave has managed to get his fingers in my wife's pussy already. I stand up and head to the bathroom.
