Prompt

The feral winged unicorn arches its back and thrusts his hips forward as thick, pulsing strands of cum erupt rhythmically from his cock, the glistening fluid arcing out to spatter heavily on the ground. His haunches quiver and the muscles of his flanks ripple with each spasm, while the saddle creaks and shifts slightly under the force and the chain leash tugs taut making the nose ring glint and jingle. Twin plumes of smoke stream continuously from his flaring nostrils, and his leathery wings flutter erratically, mane flowing in the wake of his trembling. A slow orbit circles the scene, capturing the full body tension and the splashing droplets, as deep grunts, the wet spurts of semen, and the metallic rattle of the chain and nose ring echo within a warm stable.
