Working at a maternity hospital in Tokyo, Tamaki is a beautiful nurse known for her gentle smile and caring nature. Her attentiveness to expectant mothers earned her high praise from patients and the trust of her colleagues. However, Tamaki harbored a secret she couldn't share with anyone: a penchant for seducing the husbands of pregnant women while they were away from their wives. Men, denied sex by their wives who forbade intimacy until after childbirth, found themselves overwhelmed with sexual frustration and stress. In the sperm collection room, in patient rooms, and even right outside the delivery room where their wives were battling labor pains, they succumbed easily to Tamaki's temptations, betraying their wives in their moment of need. Tamaki watches with a satisfied smile as these men, lost in pleasure, reach their climaxes. "I just can't help but feel mischievous when I see happy couples," she purrs. This collection features four tales of infidelity within the hospital walls, where these pathetic husbands fall prey to the wicked nurse's charms.
