In a dimly lit studio, Steffy, dressed in skintight yoga pants and a crop top, takes control. Her sub, bound and kneeling, watches as she demonstrates poses, her body flexing and tensing, making his cock throb. She tells him to stroke, to imagine it's her hand, her pussy. He whimpers, struggling to hold back. She leans in, her breath ragged, "Don't you dare cum." She grinds against him, her yoga pants dampening, her scent driving him wild. Just as he's about to lose it, she pulls back, leaving him a trembling, desperate mess, begging for release.
