A busty apartment complex with a lewd, slutty, intercourse, a battle of breasts with exposed rivalry, taking each other's husbands!

The Kazama and Sasayama families live in the same apartment building. On the surface, they are close friends, but their wives Nozomi and Yumi were conscious of their outstanding beauty and their glamorous, flesh physiques. One day, Nozomi sees her husband Atsushi and Yumi hanging out. When Yumi suggests to exchange cuckolds and exchanges as if to further defeat Nozomi, who is shocked, Nozomi accepts this, perhaps out of dismay. The two heat up and compete with each other and engage in a fierce battle in which they take their husbands out!
