The young wife has fallen for the muscular trainer at the gym. Momo married a very good husband but he has one weakness, which is... a physical weakness! He cannot make Momo happy. One time she went to the gym because she had a day off to work out more in her free time. When Momo spilled water, he helped her clean it up, but because Momo's body was so attractive, he couldn't resist. Momo always pretended to be disgusted, but she didn't hold back and gradually wanted more.
