A wife comes to the home of a trainer who teaches her "bodyweight training" without using any equipment and stretches that are great for toning. Once the training begins, she is made to do obscene hip-joint rotation exercises, and the trainer, claiming to be helping her, touches her sensitive parts. He doesn't care that the wife is reluctant, and continues the stretches by pressing his body against hers, completely grabbing her breasts and buttocks. However, the wife hasn't had sex in a while, so she doesn't brush his hands away, and before long she is letting out hot sighs and her heated body is dripping with lewd sweat. Before long, they start kissing each other... and this is what we secretly filmed!
