In the dimly lit room, Casey, the seasoned muscle daddy, watches as his eager twink student, his eyes gleaming with anticipation. "On your knees," Casey commands, his voice a low rumble. The twink complies, his heart pounding with excitement. Casey unzips his jeans, revealing his throbbing, uncut cock. The twink's eyes widen, but he doesn't hesitate, taking the head into his mouth, swirling his tongue. Casey grunts, guiding the twink's head, teaching him the art of deepthroating. The room fills with the wet sounds of the twink's eager sucking, punctuated by Casey's growls of pleasure.
