Cheating with My Step-Sister

On screen

A city apartment shared by a couple suddenly has a third resident with a suitcase. Quinn announces that her father said she can stay the month and asks if her stepbrother minds. His girlfriend meets her for the first time and watches her head for the shower. Quinn later crosses the living room in only a towel, and the girlfriend wants to know what her problem is. He promises a word with Quinn, though he admits to himself that he wants her badly.

How bold it gets

Mostly teasing: a towel, a visible reaction and blunt propositions. The first two episodes stay at talk and near-touch, without a bedroom scene.

Still open after episode 2

Unsettled: whether he keeps his promise to his girlfriend, and whether Quinn's offer to include her is meant as a joke.

Names you will hear: Quinn.
