On his knees, the slutty pup presents his mouth, ready for his Master's use. A thick, uncut cock slides between his lips, the foreskin rubbing against his tongue. The pup sucks eagerly, his amateur status clear in his sloppy technique, but his enthusiasm more than makes up for it. His Master fucks his face, using him like the submissive slut he is, until he's left gasping for air, drooling and dripping with saliva and pre-cum.
