The door was closed but I opened it a crack and saw Tommy standing there nude with his hands on his sister’s head as she was sucking his cock. He ha... this big ass smile on his face as his sister knelt in front of him and sucked on his cock head. He was telling her how good she was making him feel and what a great cock sucker she turned into.Then he shoved his dick deep into her mouth and she gagged as he began to cum. I watched as his balls lifted up and down as load after load of his cum. She thrust a breast in his mouth and he started suckling her nipple. Maureen cried out "Harder!" and so he bit down on it. She just groaned in pleasure. Finally she stiffened and gave a small scream as she spasmed her orgasm. Pausing only for a moment, Maureen started riding Jack hard. She jammed her other nipple in his mouth for his abuse. Finally she felt him start to spurt and she quickly lowered her groin to his. She used some kleenex from his desk to clean up a little, then she wrapped her. Her hands reach to your nipples and slowly rub them then pinch them hard and pull on the breasts, while her tongue works your clit fast and feverishly. Finally you hear her say, "If you don't cum slut the water stays in and I flog your ass for the next fifteen minutes without stop. Make up your mind cunt." Then she buries her head back between your legs and works on your clit again. Soon you find yourself reaching the peak inspite of your pain from the water held within you. Her tongue. The wife sucks, gently strokes his balls, caresses his bottom and pulls his cock ever deeper into her mouth.After 10 minutes or so of this, he waves the girl out of the pool, and towards them. After some silent eye communication and a mental power struggle, she leaves the pool, nervous, unsure, but wanting something to happen. She approaches, a raised hand stops her dead. With his hands he silently indicates for her to take her swimming costume off. Alarm, concern, excitement run through her!.
