Mustang's First Breeding Session

The sound of hooves approached from the barn, and then Stud appeared in the doorway. Cassia had seen the alpha stallion many times during her shifts, but she had never seen her like this, never been the one bent over and waiting.

Stud was magnificent in the way all great beasts were magnificent. Her long purple mane was shaved on the sides, and the septum piercing glinted in the light filtering through the high windows. Dark skin stretched over powerful muscles, and her cock, her massive eleven-inch cock, stood fully erect, the head already glistening with anticipation. She wore the same tack as Cassia. But on Stud, the outfit looked imposing.

Fabia led Stud to the frame then removed the stallion's lead and stepped back. "Break her in good, Stud. She's **** for a breeding this one."

Fabia left, and the door closed behind her.

Cassia felt Stud step closer, felt the heat radiating from the alpha's body. The stallion's cock nudged against her inner thigh, then dragged slowly through the slickness of her pussy lips, coating itself in her arousal. Cassia whimpered, a soft, needy horse sound that she barely recognized as coming from her own throat.

Then Stud positioned herself, and Cassia felt the head of that massive cock press against her entrance.

Oh, heavens.

Stud pushed forward, and Cassia's world narrowed as her pussy stretched to accommodate eleven inches of the alpha stallion’s cock. Cassia's pussy protested at the size, slowly yielding, inch by impossible inch.

Stud paused when she was fully mounted, giving Cassia time to adjust. The stallion's hips pressed flush against Cassia's raised rump, and Cassia could feel every throbbing inch inside her, filling her completely. The collar turned her panting moans into shuddering whinnies.

Then Stud began to move.

Her hips bucked forward, driving deeper, and Cassia cried out around the bit. The rhythm built quickly, hard, fast thrusts that rocked the mounting frame and sent jolts of pleasure through Cassia's entire body. Stud's cock touched places inside her that she hadn't known existed, sending tingles of pleasure up her spine.

The first orgasm hit Cassia without warning, ripping through her like a tornado. Her pussy clenched around Stud's cock, and she heard herself screaming, a high, keening whinny that echoed off the barn walls. But Stud didn't stop. The stallion kept thrusting, kept pounding into her, drawing out the pleasure until Cassia thought she might shatter.

Then another orgasm built on the heels of the first, and another, until Cassia lost count entirely. She existed only as a vessel for fucking, as a pony **** being bred for the first time in her life. Cassia could feel Studs precum dripping down her thighs, mixing with her own abundant slickness.

Stud's breathing grew heavier, her thrusts more urgent. The stallion's hips slapped against Cassia's rump with each drive, and Cassia felt something building in the alpha, a tension, a need.

With a guttural groan that emerged as a deep, rumbling neigh, Stud buried herself to the hilt and released. Cassia felt the hot flood of cum filling her, pulse after pulse of it, sloshing through her insides. The sensation triggered another orgasm in Cassia, weaker but more profound, as if her body was thanking the stallion for the gift.

Stud stayed inside her for a long moment, both of them panting, before withdrawing slowly. The sudden emptiness was almost unbearable. A river of cum immediately began to gush from Cassia's stretched pussy, trailing down her inner thighs.
