The Stable-hand

"Fabia! Morning!"

A stable-hand emerged from the barn, a broad-shouldered futa with short hair and the easy confidence of someone who had worked the ranch for years. Her eyes landed on Cassia and lit up with interest.

"Well, now," the stable-hand said, approaching with a grin. "Got a new filly, do we? I didn't hear about any new arrivals."

Fabia's hand rested casually on Cassia's shoulder, steadying her. "This is Mustang. She's just visiting from a ranch up north. Her stable's stallion injured herself during a mounting, pulled something in her hindquarters." Fabia's voice was perfectly relaxed, effortlessly convincing. "They sent her down for a breeding session while she recovers. To keep her in good condition, you understand."

The stable-hand circled Cassia slowly, and Cassia felt those appraising eyes on every inch of her exposed body. She wanted to speak, to explain, to do anything except stand here mute and displayed like a piece of livestock. But the collar turned her attempted words into a soft, nervous nicker.

"Pretty thing," the stable-hand said, stopping behind Cassia. Before Cassia could react, she felt two fingers slip between her legs, parting the slick folds of her pussy with casual expertise. "Oh, yeah. This filly is definitely in heat. Dripping like a rain barrel."

Cassia's face burned crimson beneath the bridle. The stable-hand withdrew her fingers, holding them up to show the glistening evidence, and Fabia chuckled.

"She's eager. That's why I'm taking her straight to the frame." Fabia gave the lead a gentle tug, steering Cassia away from the stable-hand. "Why don't you go check on Thunderbolt? I heard her kicking her stall door earlier."

The stable-hand nodded and headed toward the barn as Fabia led Cassia through the stables and into the training ring. The large wooden doors stood open, revealing the sawdust-covered floor and, in the center, the mounting frame.

Cassia had seen this frame in use multiple times before, had watched Thunderbolt strapped into it, had wiped off the cum from her pussy afterward. But seeing it now, knowing she would be the one positioned on it... her knees nearly buckled.

Fabia led her to the frame and began fastening her into place. Leather cuffs secured Cassia's booted ankles to the base posts, spreading her legs wide. Another strap cinched around her waist, holding her bent at the perfect angle, her rump raised high. The arm sleeve was already keeping her arms pinned, so there was nothing left to restrain, only to display.

"One last thing," Fabia said, gathering Cassia's tail. She tied it off with a leather thong, banding it upward so that it arched upward, leaving her pussy completely exposed. "There. Perfect."

Cassia could feel everything, the cool air on her slick folds, the weight of the bit in her mouth, the collar around her throat, the plug in her ass. She was completely helpless, completely displayed, completely at the mercy of whatever came next.

Fabia stepped back to admire her work. "I'm going to bring in Stud now. Don’t be nervous, she’s a good stallion, strong, well-trained, responsive to the frame. She'll give you what you came for." Fabia leaned close, her lips brushing Cassia's ear. "Just remember to breathe. And try to enjoy yourself. I’ll give you both half-an-hour together once I’ve brought her in.”

Then Fabia was gone, her boots receding across the sawdust floor, and Cassia was alone with the mounting frame and her own hammering heart.

She didn't have to wait long.
