The chubby sub, hungry for his master's cock, licks his lips in anticipation. The master, a towering figure of dominance, stands tall, his leather pants creaking as he shifts his stance. The sub reaches out, fingers brushing against the master's crotch, feeling the growing bulge. With a swift move, he unbuckles the master's belt, pulling down his pants. The master's cock springs free, a thick, veiny monstrosity that makes the sub's mouth water. He leans in, wrapping his lips around the head, tasting the pre-cum that's already leaking out. The master's hand grips the sub's hair, pulling him closer, forcing him to take more, to gag on his cock. The sub moans, his eyes watering, but he doesn't pull back. He's here to learn, to please his master.
