Four boys punished by the headmaster

The bearded man in the center spanks the slim boy bent over his lap, his palm cracking against bare ass while the others kneel in submission, wrists bound by green straps. The muscular man adjusts the stocky boy’s underwear, fingers lingering on his hole before pulling him upright. Hands clasped behind backs, the dark-haired group shifts between punishment and shared dominance, their naked bodies exposed as the authority figure oversees the discipline.
