Jack and Sue enjoyed the cool breeze across their skin. Like many of their recent rides, they found that they simply loved sitting side by side, holding hands and watching the scenery. Jack still noted with pleasure the strangeness of the situation. Riding a pony cart was one thing, but having it pulled by a ponygirl was another.
It hadn’t taken long to train Diane to act as their horse. She responded to the reigns well, even detecting the slight adjustments that Jack offered from time to time. He often admired her sleek form. A week of constant rides had toned her body nicely, and given it a soft brown tan that suited her well.
Jack had thought it would be more humiliating to have Diane naked as their horse, out in the middle of nature with nothing to hide her modified body. Sue had agreed, but both compromised in a few areas.
First, her corset had remained intact. A week ago, the shop at the resort had delivered what would end up being Diane’s final corset. Made of a combination of leather and steel, the form had no laces, but instead closed to the 17-inch waist that Diane had been trained to. With a series of rivets, the device became a permanent part of their slave’s body.
Of course the chastity belt remained as well, with a couple slight modifications to ensure that not even the belt itself could make contact with Diane’s clit, even through the fury of a gallop. Both had wanted her to pull them in ballet shoes, which proved to be the most painful aspect for Diane.
Finally, her head was completely hooded, blocking out all sight and sound, with her mouth left open for the bit. Using the rods set into her tongue, the long flange connected to the bit, like a tongue depressor, rested on top of her tongue, then was affixed to it, holding it rigid. A ring at the center of the bit connected directly to her nose ring, holding it in the center, while short chains from the ends connected down to her nipple rings. When Jack or Sue tugged on the reigns, the input was transmitted not only to her bit, but also to her tongue, septum and nipples.
Her arms had been folded up behind her, so that her wrists nearly met the back of her wide steel posture collar. A short chain held her arms up, while her hands had been balled up, rendering them useless. The result was that Jack had a clear shot to her breasts with the buggy whip. Even from directly behind her, her even larger breast size, now a 38GGG, looked like two slightly saggy beach balls. In truth the breasts were quite firm, just very very large.
The cart was connected to Diane via rings on the side of her corset, holding her firmly in place. Loops of leather circled the base of each breast like a noose, then reached up over her shoulders to connect to a bar behind her, keeping her body straight and upright. Diane looked amazing as a pony, and Jack secretly planned to keep her this way for some time.
Behind them, trailing via a short piece of chain, was Debbie. Like a pack animal, she was being pulled behind the cart, if for no reason other than to provide her exercise. Unlike her sister, Debbie was fully covered in latex, reaching from her neck to her toes. Sweat rolled off of Debbie’s face from the prolonged exposure to the hot sun in the heavy latex. Sue had added two tight bands at the base of her breasts, forcing them to stretch the rubber even further as they became engorged from the lack of circulation.
From time to time, Sue would reach back and slap her slave’s tits with a cane, bringing new tears to the young girl’s eyes. She could do little to resist, with her arms bound at wrist and elbow behind her. Above her seven-inch heels, which tortured her feet horribly, her ankles were encircled by cuffs. A chain led from one side, up between her legs, to the base of a dildo planted deep in her ass, held in place by a chastity belt. The dildo was electrical; if both feet remained down on the ground for more than two seconds, a harsh shock would course through the dildo. Jack had envisioned a larger carriage pulled by the sister team, and figured training the younger girl to high step like her sister was a wise start.
To add to her humiliation, Sue had decided to add a similar grommet and ring setup to Debbie’s septum. The chain connecting her to the cart was attached to a large ring, tugging her along by the nose. Completing the picture was the huge gag in her mouth, held on by a wide leather strap that compressed her cheeks tightly.
After a good hour ride, Jack steered the cart to a rise, where he popped out a small picnic basket, quickly setting it out on the ground.
“It seems you had this all planned,” Sue joked as she took a glass of wine and admired the late day light. Jack, too, took a moment, reveling in his newfound life. He watched Sue for a moment, admiring her beauty. As usual, she had chosen a purple latex dress, short and tight, that outlined her body perfectly. After a moment, he glanced over to the cart, watching Diane catch her breath from the last run up the hill. From the side, her long, lithe form was perfect, even with the huge breasts protruding from her chest. Her tiny waist contrasted nicely with her shapely, toned ass. Even her legs looked perfect as she stood carefully in her ballet shoes. Looking to the back of the cart, Jack chuckled as Debbie struggled to stay on a single foot, almost literally prancing from toes to toes, while simultaneously tossing her head to rid the flies. Her long hair flowed in the breeze, creating a look of a true pony.
“This is nice,” Sue nearly whispered, nuzzling closer to Jack. He smiled, enjoying her, the world and his life.
“So, Sue, I was wondering,” Jack trailed off, fear clutching his heart for a moment. He watched her look up at him, warmth in her eyes that calmed him. “I was wondering if you would consider marrying me.” Sue’s eyes filled with tears and her expression changed. For a moment Jack was certain he had ruined everything. Then suddenly he was tackled to the ground, and Sue was kissing him frantically.
“I thought you would never ask!”
