His sister-in-law has run away from home after a fight with her boyfriend, but his wife is working overtime and doesn't come home, leaving him alone to deal with the situation. The reason for the fight seems to be a lack of sex, and he gets drunk and seduces his sister-in-law to see if he is not attractive enough. He knows he shouldn't, but he can't contain his arousal at the sight of her body, which is younger and more desirable than his wife's, and he finds himself drowning in her pussy.
