To Catch a Cheater

In the initial scene, a caring spouse named Joe is driving, gazing adoringly at his wife Vanessa, who is applying makeup in the car. He offers to wait for her but she declines, noting the short distance left to walk. Joe affectionately bids her farewell and leans in for a goodbye kiss, which she ignores as she exits the vehicle.
Vanessa then heads to a house and meets a teenage boy, whom she presumes to be Joe's son. Upon entering, she learns that the boy lives with roommates. The boy, curious about her marital status, asks if she is married.
Vanessa cryptically responds that her relationship status is complex. The two proceed to a bedroom, where Vanessa seduces the boy, who is a virgin to such encounters. As things escalate, Vanessa notices a family photo of the boy and Joe, at which point she reveals the real connection she shares with Joe.
Shocked, the boy threatens to expose her escapade but Vanessa resorts to persuasion, except when things take an unexpected turn as a manipulative twist is uncovered during a compromising twist of events.
