You've had to stay behind with your friend's mom, and whilst she speaks with your mom on the phone you keep peaking at her cleavage and stocking tops - until suddenly she pulls your dick out and starts stroking, sucking and wanking it between her tits whilst telling your mom what a delightful boy you are. You have to keep very quiet until she's done on the phone and she can ride your dick, front and back, like she's been fantasising about for far too long!! Until her husband calls to say he's on the way - you think you can finish in time with your dick back between her huge heavy breasts?
