Lip nibbling along the spine of the mare brings upon her the rising of her tail and a presentation to you of her excited and winking vulva.
This stuns you, and eying this close up, the sensation offered to you by her scent there is something astounding.
The sheer weight of your male member filling and dropping out the sheath is startling!
As it fills and becomes mobile to your manner of thinking, the remembered word "Libido" comes to mind, as a stallion penis hangs stiffly, stout to the purpose at hand, and with mental working of it, you can stiffen it, make it rise up, bumping your furry belly and granting a wild sensation worthy of that heightened moment of passion.
The next step is one like taking a long walk off a short pier.
A fore leg leap up and your front legs ride on her spine, as you move your hind legs and pelvis into a more lucrative position.
Libido surges, and with plain Dutch sort of luck your flared end to one elongated monster of a horse cock presses past her vulva lips and begins a decent into the hot depths of her erotic feeling body.
Wild are your eyes, a reflection of a mind stunned from such sensations, the mass of feeling engulfing your human mind in a equine fog of predetermined action and reaction.
Pelvic rocking causes penal thrusting and the sensation to both stallion and mare are worth their cursed damnation if hell is as real as the heavenly feeling you are having, mated, coupled, and mating with a mare.
