The room is filled with the soft creaks of the chair and the boy's ragged breaths. He leans his head back, eyes closed, imagining the touch of a whip, the sting of a crop. His cock tents his briefs, aching for release. He grinds harder, faster, his body slick with sweat. The chair groans in protest, the boy's moans growing louder, more urgent. He bites his lip, his body tensing as he nears the edge. The room fills with the sound of his ragged breaths and the wet, slapping sounds of his cock against his belly as he fucks the air, his body convulsing as he finds his release, his cum soaking his briefs, his body trembling with the aftermath of his solitary, bound indulgence.
