A work depicting the behind-the-scenes of erotic training sessions conducted before married women are hired at a brothel, each with their own reasons for seeking employment. It reveals the hidden desires and true feelings of young wives that their husbands know nothing about. Women suffering from sexless marriages and pent-up physical and emotional frustration gradually become aroused during skill training with staff, losing themselves to the sensation of a cock after so long, or experiencing thigh sex for the first time. Their secret passions and desires—things they could never tell their husbands—are vividly portrayed.
