Two characters: a feral male wolf and an anthro female protogen. The wolf's hips drive forward in a single deep, powerful thrust, his sheath and knot root sliding fully into her vagina with a wet, heavy slap, her body jolting forward from the impact, his forepaws gripping her hips tightly as she gasps and tenses, her leg held up and trembling. The motion is a single continuous, forceful push that ends with the knot swelling and locking inside her, her body shuddering against him, his fur and her synthetic coat shifting with the impact. Soft warm daylight from the side. The wet slap of flesh meeting flesh, a sharp gasp from her, and a low growl from him. 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.
