Edge of the Burn: Rules of Submission - by Brooke Briggs

When her stepson returns home, Lena Briggs expects another disciplined athlete to train. What she gets is a slow, irresistible unraveling of every rule she’s built her life around. As their shared workouts turn competitive and charged, friendly bets evolve into something far more dangerous. Light restraints made from her own resistance bands. Blindfolds that strip away sight and amplify every touch. The slick heat of sweat-slicked muscle against muscle. Commands whispered in the dark while his father sleeps upstairs. Lena has always prided herself on control—her sculpted body, her iron discipline, her carefully maintained life. But Alex’s growing dominance awakens a deep, aching need to surrender. What begins as stolen glances and teasing penalties becomes raw, sensory-driven passion that pushes them both to their limits: temperature play on heated skin, powerful athletic positions that leave them breathless, and whispered confessions between shattering climaxes.
