It's been a few years since they got married... Takashima and his wife used to spend the night before holidays, but it's been quite a while lately. The libido of Misuzu, a wife who indulges in masturbation while her husband sleeps every night, has already exceeded the limit. One night, she entertains her subordinate, Mochizuki, at home, but her husband gets drunk too much, leaving Misuzu and Mochizuki alone. Mochizuki is about to go home because she's too nervous, but Misuzu suddenly squeezes her crotch and says, "You've been watching me all this time, haven't you?"
