At the touch of the mare's velvety muzzle , he started to grow aroused again. His large black flaired horse cock falling from its sheath. He lifted his head high wrinkling his lips at the mares scent, taking in the stink of her urine and manure that lay on the ground around them. She sensing his arousal, lifted her tail releasing a torrent of pheromone laden piss.
Turning to face her rear, her tail lifted to the side exposing her black winking lips, he liped her sex. Suddenly his head began to swim as new instincts flooded his large equine head. Instead of wanting to mount, something deep inside was pushing him to lower his head to nurse.
The mare growing impatient , pushed her large muscled rear back at her strong stallion. Shaking his head in frustration he attempted to mount only to find he'd shrunk, causing his nostril to land against her puckered black anus and slide down her sex. Sighing in frustration the lusty mare swung her long neck back only to find her stallion a week old foal, his tiny horse cock still unsheathed and ready for action. She hurred as if to chuckle. Now only old enough to suck from her teats.
Not giving up the tiny foal attempted to mount his mare soon to be dame again only to have his head slide down her piss soaked legs, falling to the ground as he lands on wobbly newborn legs. The mares teat magically filled with milk she lowers her head to help her baby stand. Urging him to drink from her teats.
