In the dimly lit den, Mark's daddy, a grizzled, hairy-chested man, takes off his belt, the metal buckle clinking ominously. Mark, a twink with a mop of brown hair, stands before him, his heart pounding, his breath hitching. 'Bare your bottom, boy,' the daddy commands, his voice rough with lust. Mark complies, his cheeks flushing as he exposes his tender, pale flesh. The daddy brings the belt down, the leather singing through the air before landing with a sharp crack on Mark's quivering ass. Mark gasps, his cock twitching as the spanking begins in earnest.
