How My Roommate Won Her Body by Lulu Lust

Length: 9,600 words

A simple workout bet. A devastating loss. And now his roommate owns the right to train his wife—any way he wants.

Henry never thought a five-minute challenge in their cramped living room would change everything. When his cocky, muscle-bound roommate Ethan bets him that he can’t keep up, Henry—desperate to prove he’s still a man—puts his pride on the line. The stakes? If Henry loses, Ethan gets one full month to personally “train” Aya, Henry’s gorgeous, quietly sensual wife.

Henry loses. Badly.

What starts as strict fitness sessions quickly turns into something far more dangerous. Sweaty, hands-on corrections become lingering touches. Partner stretches become grinding intimacy. And Henry—forced to watch from the shadows as spotter—discovers a humiliating truth: the sight of his wife surrendering to Ethan’s dominance doesn’t just break him… it arouses him like nothing ever has.

As Aya’s body awakens under Ethan’s commanding guidance, and Henry’s shame twists into dark, addictive need, the lines between husband, roommate, and lover blur beyond repair. Every session pushes them deeper into forbidden territory—until the only question left is how far they’ll go before someone claims permanent ownership.

A raw, psychological cuckold thriller packed with unrelenting erotic tension, power exchange, voyeuristic humiliation, and sweat-drenched desire. For adult readers who crave the slow burn of betrayal, jealousy, and irreversible surrender.
