MFYD-086 | While my son was playing with his friends at the public pool for eight hours, I was having an affair with the coach of his swimming lessons... Kitano Mina

Married for several years, Mina lives with her husband and only son, Takashi, and is beginning to feel a bit bored with her mundane daily life. One summer day, she goes to the public pool to return something her son forgot, and meets Yuta (a university student), the swimming coach. The story begins when she bumps into him on the street a few days later and invites him over for dinner. From that day until the end of the summer, Mina becomes addicted to having sex with her son while he is at the pool... When a mother transforms into a woman, no one can stop her.
