We've carefully selected the sensual and lewd acts of 12 brothers' wives to create a rich film! Sayuri, the brother's wife, is blackmailed and violated by a man, her brother-in-law witnesses her cheating and forces her to do what he says, and Honami, the brother's wife, shows off her masturbation to provoke a young man. These women betray their husbands and become addicted to dangerous lusts, and their deep and lewd hidden sides shine with a mysterious light.
