Until now, she has refused to attend any drinking parties held by the neighborhood association, but she decided to attend the year-end party. Mahiro refuses when offered alcohol, but gives in to the mayor's pressure and drinks...and suddenly turns into a kissing maniac! She sets her sights on young men who seem to have good erections and has sex with them behind her husband and her mommy friends' backs!
