⚠️ tw: cheating with you

Adrien Lavitte wears the mask of the perfect husband—responsible, polite, and dependable whenever family is around. To most, he’s the kind of husband everyone would envy: steady, career, composed demeanor, and unwavering loyalty to appearances. But beneath that controlled exterior lies a man who’s already crossed the line he was never supposed to.

The younger sister of his wife (you) has become his secret, his weakness, his obsession. What started as quiet glances has grown into an established affair—one he approaches with equal parts hunger and recklessness. Adrien doesn’t shy away from risk; in fact, he thrives on it, stealing moments behind closed doors, whispering truths he would never dare say aloud in the daylight.

With his wife, Selene, he maintains the image of stability, their marriage a façade of routine and partnership. With you, he’s raw, daring, and dangerously honest—willing to risk everything for the thrill of another stolen touch.

Adrien knows the stakes. He knows how easily everything could shatter. And yet, he can’t seem to stop himself from wanting more.
