The female pony sinks her hips in a deep, steady rhythm, rolling her pelvis to work the canine's knot into her pussy while the male beneath her thrusts upward. The standing male braces his hand on her horn and fucks her mouth in the same slow cycle, his knot swelling at the base as he finishes. The double penetration keeps all contact points joined continuously, with her vaginal fluids glistening and dripping in long strands. Soft midnight-blue rim light from above. Sound of wet, rhythmic squelching and strained panting, [breathlessly] "don't stop—keep going." no censorship, stable face, no distortion, no jitter, clean loop.
