One day, deep in the African forest, Fumiko is sent to a primitive, isolated village. She rapidly develops a close bond with the village leader because she is an outgoing person.

Because of their strong bond, Fumiko feels comfortable discussing her personal life. She talks about her interests, her husband, her family, her personal issues, and occasionally even the subjects of Fumiko’s sexual life.

The village chief has a rather warped personality and doesn’t say much. However, Fumiko felt at ease being close to the village chief. Mr. Kela, the village chief, occasionally engages in filthy behavior, such as pinching Fumiko’s behind. Fumiko was uneasy at first.

But as time passed, Fumiko stopped being bothered by the elderly man’s approaches and obscene behavior; instead, she accepted them as commonplace and dismissed them as a joke.

Will they eventually cross the line, though? Okimura Nagato, Fumiko’s spouse, is a heartless man who has never even satiated Fumiko’s erotic desires. Okimura Naoto, the 18-year-old son of Fumiko, frequently calls his mother a gorilla as a form of bullying.

He was unaware that this caused his mother to feel self-conscious about her appearance and that stress could cause her to fall in love with someone else.

One day, while they were using a computer to communicate, Fumiko’s special computer developed a fault that allowed Naoto to view everything his mother did, even though she had turned it off. What will Naoto see then? Will he come to regret how he treated his mother?
