Although they are other men's wives, these five lewd wives exude a feminine scent and attract men like moths to light. Attracted by their strong pheromones, the men decide to have sex with them at night. The sound of clothes rustling and the obscene sound of their bodies being thrust in and out of their crotches echo from the futon. Eventually, their movements speed up, and the lewd wives end up receiving the thick sperm of other men in their uteruses.
