A housewife is frustrated by her husband's long business trip. One morning, she chats with the men living on both sides of her apartment while taking out the trash. One's wife is away visiting her parents after giving birth, and the other is a divorced single man. Little did she know what would happen then. At a reunion, a drunken beautiful wife mistakenly goes to the wrong house and ends up having forced sex with a neighbor. On another day, she shares food with the divorced neighbor, who confesses his feelings and performs oral sex and fellatio. Furthermore, she engages in a threesome with the two men and becomes aroused.
