In the gym

Lily keeps her lines long and tight. Today the mirrors watch her stretch, thighs parting, calves flexing. Her tank sticks to damp skin, panties already damp. She peels them down, lets them dangle from one ankle, and brings the silver speculum into view. Cool metal kisses her heat. She turns the screw with steady fingers, opens herself inch by inch until the lips part and the tunnel gleams. She breathes slow, then faster, watching the bright circle inside her. Her nipples tighten. A soft sound escapes when she twists it wider, thighs shaking. She slides two fingers through the gap, curls them, pulls a thread of wetness that stretches and snaps. The metal catches the light every time she rocks her hips, every time the stretch turns into a pulse she can’t hide. She keeps the frame open, holds it, and rides the edge, eyes fixed on the reflection of her own glistening center.
