One character, a male wolf, and one character, a smaller female, joined in anal penetration from behind with her legs up, he thrusts into her in one steady, deep, continuous cycle, his hips rocking forward and back with firm pressure, her body swaying with each push, his growls low and guttural as her moans rise and fall, the contact point between them stays locked, her soft flesh jiggling with each impact, fur shifting along their backs, dim cold moonlight filtering through the forest canopy from above, the sounds of his growls and her moans mixing with the rustle of leaves, 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.
