Mary looked all over the stable, until she finally locked eyes with a large black stallion. His cock was even bigger than her own. She could feel her dark mare pussy throb just looking at it. She needed that horsecock more than anything else.
She approached the male and got down to her knees, ready to suck. She teased the flared tip of his mottled cock, caressing his huge balls. He let out a whinny out of pleasure. Musk hitting her nostrils, she got hooked on the flavour of his salty pre-cum, this was what a real horse cock tasted like. It was simply intoxicating, she couldn't stop. Both her hands worked his long, veiny lenght. She couldn't take it anymore. Her needy horse pussy needed to get fucked. She bent over in from of him, exposing her wet cunt. He immediately mounted her, and shoved all 4 feet into her gaping ass.
"Ooooh fuuuuck!!!" The pain was unbearable, but it soon made way to the most euphoric feeling that Mary had ever had. Her doughut got stretched wider than she had ever thought possible. She couldn't stop moaning. The stallion pounded her like there was no tomorrow, and filled her ass with hot, sticky cum. It leaked as he pulled out.
Mary needed more, and immediately fisted her gaping hole to dig out the cum. She hungrily licked her fingers and cleaned off the stallion's cock. She could never go back to humans again.
