Her Gym Instructor Turns Her

Mia has a boyfriend. A nice one. The kind who wears chinos and asks about her day and makes perfectly adequate love on Saturday nights. She's twenty-four, works in marketing, lives in a one-bedroom flat in Bermondsey, and goes to the gym three times a week.

Her life is fine. Completely, utterly, boringly fine.

Until she starts noticing Sasha.

Head trainer. Russian. Tattooed from shoulder to wrist, muscles that speak of years under heavy weight, and a voice that makes Mia forget how to breathe. Mia tells herself she's just admiring her form. Her technique. The professional way she corrects deadlifts and loads barbells.

She's definitely not screenshotting Sasha's Instagram posts and hiding them in a folder labeled "Recipes."

When Mia finally books a personal training session, she thinks it's about her plateau. About needing proper programming. About finally hitting that ninety kilo deadlift.

Sasha knows better.

Because Sasha has been watching Mia for six months. Watching her blush when their eyes meet in the mirror. Watching the matching gym sets get tighter, the glances get longer, the shower sessions in the disabled cubicle get louder. Sasha has been patient. Waiting for the right moment. Waiting for Mia to be ready.

And when that moment comes, when Sasha finally locks the door to the stretching room and says "you can leave, or you can stay," Mia learns exactly what she's been craving.

Her Gym Instructor Turns Her is an intensely erotic story of obsession, submission, and the kind of training that changes everything.
