Mahiro, a young wife who turns into a kissing maniac when drunk, usually avoids drinking alcohol as much as possible. She had declined all invitations to the neighborhood association's drinking parties but decided to participate in the year-end party. Although she refused offers of alcohol, she eventually gave in to the town mayor's insistence and drank... turning into a kissing maniac! She sets her sights on a young, seemingly virile man and secretly has sex with him, hiding it from her husband and mom friends.
