The headmaster's hand trembles slightly as he caresses the black-haired boy's ass, feeling the heat and the firmness. He brings the paddle down hard, the sound echoing through the room. The boy yelps, his body jerking forward, his cock tenting his uniform. The headmaster smirks, enjoying the boy's discomfort and his obvious arousal. He spanks him again, and again, until the boy's ass is a bright red. Then, he moves on to the next boy, leaving the black-haired one to rub his sore ass, his cock throbbing with a mix of pain and pleasure.
