Chapter 3: Hip Thrusts and Tension

Sarah Thompson killed the engine in the far corner of the lot, the sudden quiet pressing in like a held breath. Two days had passed since those goblet squats, yet the echo of Mike’s thumbs anchoring her hips refused to fade. She’d spent the hours in between convincing herself the flutter in her stomach was only workout anticipation—nothing more. Still, when she stepped out into the thick evening warmth, the cropped tank top she’d chosen felt bolder than she’d intended. Same black leggings, but now paired with a black sports bra beneath the hem that rode just high enough to bare a narrow band of her soft midriff whenever she moved. It’s hotter in here at night, she’d reasoned in front of her bathroom mirror, tugging the fabric lower then letting it snap back. Better airflow. The lie tasted like salt on her tongue as she crossed the asphalt, the faint scrape of her sneakers the only sound.

The doors parted with their familiar hush, releasing a wave of cooler air laced with the sharp bite of fresh rubber flooring and the distant metallic ring of a lone weight stack settling somewhere deep in the cavernous space. She spotted him immediately across the open floor, and her stomach performed a slow, treacherous flip. Mike stood beside the flat bench, barbell already racked and loaded with plates that glinted under the low lights. His black tank clung to the clean lines of his torso from whatever warm-up he’d done earlier, the fabric darkened in faint patches along his spine. He turned at her approach, that steady hazel gaze sweeping over her once—professional, yes, but catching on the exposed strip of skin at her waist before returning to her face.

“Sarah. Right on schedule.” His voice carried the same low calm that had lodged itself in her thoughts, but tonight it felt heavier, closer. “I remembered you wanted to hit those glutes hard. Figured we’d start with hip thrusts tonight—barbell loaded light so we can nail the form first.”

He didn’t wait for an answer. He dropped smoothly onto the bench to demonstrate, shoulders braced, feet planted wide, hips rising in one powerful, controlled drive that lifted the bar clean off the pads. Sarah watched the long, fluid line of his body—the flex of his quads, the deep crease where his shorts rode up his thighs, the way the motion pulled every muscle taut before he eased back down with a quiet exhale. Heat bloomed low in her belly, sudden and undeniable, a slow unfurling that made her shift her weight. Stop. He’s showing you the move. That’s all.
