The store's dim lights flicker as the clerk, consumed by a sudden, intense heat, starts to touch himself. His calloused hands, used to handling goods, now grip his pulsating cock with urgency. He leans back against the counter, legs spread wide, imagining a customer walking in, catching him mid-act. His strokes become faster, more aggressive, his balls tightening as he nears his release. The store's silence is broken only by his guttural moans as he spills his load onto the floor, his body trembling with the force of his orgasm.
