Mu-chan was having a sad day when she saw her parents getting sick. In particular, Mu-chan knew that her mother was lonely because she wasn't SEX-less and couldn't be made a father. Mu-chan gradually began to play sexual mischief with such a mother. If the dad is sleeping or steals his eyes in a space that he doesn't notice, Mu-chan, who mischiefs his abundant body, will take his favorite mom from his dad.
