In a dimly lit room, a leather-clad dominant commands his submissive to service him. The sub, bound and collared, crawls towards his master's crotch, unbuckling his pants to reveal a rock-hard cock. The sub's tongue flicks out, tasting the pre-cum, before he takes the entire length into his mouth, gagging slightly. The dominant smirks, holding the sub's head in place, fucking his mouth harshly, leaving the sub gasping for breath.
