One feral male dobermann, standing quadrupedal and facing the viewer, gives a few short, sharp barks with his muzzle opening and closing, his tongue flicking out briefly between barks while his ears twitch and his head bobs slightly. His hips give a subtle, rhythmic rock as his knot stays swollen and his dripping penis glistens, saliva stringing from his jaws with each motion. Soft warm daylight from the front-left catches the wet fur and slick fluids, with the faint echo of his bark and the wet sound of his tongue. static camera, single continuous shot, one full frame, clothing unchanged, same art style, anatomy holds its shape throughout, limb count never changes, hands keep five separate fingers, no extra characters or limbs, stable face, motion continues to the last frame, sharp and clean, no distortion, no jitter, no background music, no watermark, subtitles or text, no censorship, clean loop.
