GrowingMuscleBro hauls the blue pouch taut over his crotch, restless and insatiable

In a dim room, GrowingMuscleBro drags a blue pouch up and down across his crotch, both hands yanking the fabric tight while his thighs bunch and flex beneath a grey tee. The dark strap stays looped around his waist, and the pouch swings and stretches between his fists as his breathing picks up. He keeps tugging, knuckles whitening, jaw set, chasing the pull of it until the fabric strains against his grip.
