Two characters, a feral wolf mounted behind a white moth, knot buried deep inside her, the wolf's hips pull back until the ridge of the knot strains against her entrance, then slam forward with a heavy, wet thud that drives the knot fully in and makes her abdomen bulge visibly, his claws gripping her hips as her body rocks with each impact, her wings trembling and fur rippling with the force, a low growl from the wolf and a sharp, breathy gasp from the moth, soft warm daylight from the left, 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.
