Hearing the man gasping in pleasure, the dog shifted, his big paws resting on either side of the man's hips, mounting him as he would any bitch that was ready for him. He began thrusting his hips, whimpering softly as his c*ck throbbed, aching to be inside something warm and tight. The dog growled softly, teeth nipping and snapping at the nape of his neck. The dog thrust one last time, feeling his hard, aching c*ck slide deep inside the man's tight opening. Positioning himself, he began to thrust wildly into the man, hips pistoning, ramming his big c*ck into the poor man's tight little hole, using him ferociously.
