When David gave his wife private guitar lessons for her birthday, he never imagined where those Thursday evenings would lead.
Emma lights up during her sessions with instructor Jake-laughing more, glowing in ways David hasn't seen in years. At first, he tells himself it's just the joy of learning something new. But as weeks pass, David notices the little changes: the extra attention she pays to her appearance before lessons, the flush in her cheeks afterward, the way Jake's hands linger on hers during chord corrections.
By week four, David finds himself in the hallway, watching through a cracked door as Jake's "hands-on" teaching style crosses lines that should matter. He should be angry. He should stop this.
Instead, his body responds with shameful, undeniable arousal.
When David finally catches them together-Jake buried deep inside his wife on their marital bed, Emma's eyes locked on her husband's face as she confesses how perfect it feels-everything changes. The humiliation burns. The jealousy tears at him. But underneath it all is something darker, more primal: the twisted ecstasy of watching his wife come apart for another man.
As Emma suggests he pull up a chair and watch properly next time, David realizes he's discovered a hunger he never knew existed. Some doors, once opened, can never be closed again.
