She saw Nancy pull her legs up, her knees sticking up on each side of Josh's thighs. She knew that they were about to have sex, or "fuck" as some of her more experienced friends at school called it.
Jeane saw Josh's buttocks tighten as he pushed against his wife, and she realized that he must have just put his penis inside of her vagina. Jeane almost giggled out loud. She was thinking in the terms which she had seen in the books. Her friend, Jill, would have said that he just stuck his dick in her pussy. As she watched, she saw his buttocks tighten and relax as he thrust into his wife and then withdrew. Jeane lay very still and watched his butt, looking at the way the muscles tightened and relaxed as he repeatedly thrust and withdrew, thrust and withdrew. Josh was doing it faster now. His buttocks were clenching and relaxing at a much faster rate. She could hear Nancy sort of moaning and groaning in time with Josh's thrusts. It sounded like she was really enjoying what she was getting. Jeane saw Nancy's hands slide down over Josh's ass. Nancy had hold of his checks, pulling and pushing, encouraging him in his thrusts. Suddenly, she saw Nancy's legs jerk upward and heard her begin to kind of moan and cry. She saw Josh shove forward hard and hold tight up against her. His buttocks were clenched tightly and she could hear him gasping and groaning. She realized that they must be "climaxing" and that his organ must be shooting his stuff up inside of her.
After a few moments, they lay still. Jeane was hoping that he would raise up and that she would see his dick when he pulled it out of her, but he got up and pulled his pajamas up before she could see anything. He then went off to the bathroom leaving Nancy still spread-eagled on the bed. Jeane drifted off to sleep.
