I gently nudged my son awake. He sat up and looked at me. "Mom..." Yes Mark" I can see your boobs." he said sheepishly"Firstly it was your idea for me...to use my dress as a sun block. It's not my fault it got lost at sea. Secondly, I have learned that strapless bras are totally unsuitable for prolonged use in salt water. And the third point is my son is not the gentleman I brought him up to be!"I made no effort whatsoever to cover myself as I began my rant. I could feel him trying not to look at. “Yes Master Daddy your slut daughter is about to cum for her Master Daddy and I desire to feel His cum in my fucking ass. My only desire is to please you and become the cock sucking cum swallow fuck slut you desire me to be... please ass fuck your whore Master Daddy cum up my ass”! With that I started shooting deep in her ass and she started trembling and started an explosive orgasm herself. Her juices where flowing out of her and her cum was running out on the bed as I pulled from her. . Within two or three thrusts she’d cum, then again, then again. Her body spasmed and shuddered, her cunt gripping and pulsing on my thick hard cock, my meat hard and rigid inside her soft wet body. It was at least a minute of fucking before she even thought of turning her head, even seemed to understand that a stranger was fucking her, the pleasure and fulfilment of her fantasy had been too much, and she’d not realised reality had become, well, real. She shook herself, tried to turn herself to. So I looked back at him and said give your mother a sweet slow fucking in her brown eye my darling boy. True to his word he ground his cock into me when he was as deep as he could go. Timmy stirred and looked at us and smiled. He said I’ll leave you two alone to enjoy your Sunday anal love making. He said but I’m going to have to jerk it watching you two. Richard said I have a better idea, I said oh? And he rolled us over so I was laying on top of him and he told Timmy to eat my pussy as he.
