Choosing to live as a parasite aunt, she decides to secure her own happiness by infiltrating someone else's household. Her new target is a newlywed couple who moved in next door. Every day, she prepares meals for the husband who works from home, gradually touching his body and seducing him. She performs fellatio to provide sexual favors and obtains a spare key. While the husband is away on a business trip, she prepares drinks to welcome the young wife. In the couple's bedroom, they enjoy lesbian sex. Fully embedded into their lives, the aunt kisses the husband in front of the wife and even shares baths with him. Eventually, during a threesome, the husband ends up ejaculating inside the aunt.
