KAM-256 A frustrated body begins to ache, and a busty unfaithful wife has an affair with the men living in the neighboring apartments. While her husband is away on a business trip, Shirayuki Mitsuki loses control and indulges in forbidden encounters

A married woman is feeling restless while her husband is away on a long business trip. One morning, while taking out the trash, she chats with the men living in the apartments on either side of hers. One has gone back to his hometown because his wife is giving birth, and the other is a divorced single man. She never imagined things would turn out that way.

At a class reunion, the wife gets drunk, goes to the wrong home, and ends up entering the neighboring man’s room, where she crosses a line with him. On another day, after sharing a meal with the divorced neighbor, she is pursued by him and becomes involved in a heated affair. Later, she gets carried away in a three-way encounter with both men.
