A middle-aged wife becomes obsessed with a student, who has a crush on her stepdaughter. Every time the young man becomes intimate with the daughter, the woman fantasizes that she is with him.
Cheating Notes
The wife, a guidance counselor at her stepdaughter's school, leads a secret life to satisfy a sexual kink: on certain nights, she poses as a street hooker, engages in intense heavy petting with the men who pick her up, and then blue-balls them right before sex by slipping away when she gets the chance. We see her do this with a client at the beginning of the movie. She steps out as soon as he enters the bathroom and laughs at the hotel lobby, enjoying the moment, before leaving.
Erin, the stepdaughter, kisses her boyfriend on the dance floor while simultaneously checking out Vincent, a fellow student working as a bartender (06:11). She then proceeds to have a lesbian coupling with a friend in the bar's bathroom, and it turns into a lesbian threesome when another friend joins in.
The wife gives a young client a striptease, then blue-balls him by leaving him tied to a chair (31:31). She steals his clothes, wallet, and watch before leaving—not for financial gain, but to satisfy her kink.
Erin trades looks with Vincent while dancing with her boyfriend again (35:37). Vincent drives her home later. She's feisty toward him, but this starts their interaction.
After acting feisty towards Vincent, Erin kisses him lightly in the school lib (44:00). In the next scene, they have sex in the bedroom. They hang out and act sweet together in school in front of other students after that, despite her having a different official boyfriend.
When her boyfriend can't make time for her, she introduces Vincent to her parents as her new boyfriend, but it's just for show to piss her dad off. After lunch, they have sex on the couch (55:25). Her mom sees them doing it and records it on her phone.
The wife masturbates to Vincent and her stepdaughter's sex video while imagining that Vincent is having sex with her (1:00:31). Her husband almost catches her and asks her why she's naked on the bed.
Erin is with another young client (1:00:55). He is aggressive, so she isn't able to blue-ball him and gets graped instead. The young man throws money at her after. She calls her husband after and gives him an excuse on why she can't come home that night. She stays at the inn with bruises on her face.
The wife asks Vincent to come over to the inn. He consoles her, and still with bruises, she has sex with her stepdaughter's boyfriend (1:12:01).
The husband sees the video of her daughter Erin and Vincent screwing, then he sees his wife kissing Vincent on the mouth at the hospital, where the latter is confined in a comatose state (1:21:59).
The wife has sex with Vincent, but she has separated with her husband at this point (1:37:18).
