First race

After weeks of intense training, you and the other pony girls are finally deemed ready for your first race. You're led out to a large track, where a crowd of people have gathered to watch the spectacle.

You can feel your heart pounding in your chest as you're led to the starting line. The other pony girls are also there, all of them decked out in their latex ponygirl outfits.

The starter's pistol fires, and you take off, pulling the cart behind you with all your might. Your hooves pound against the track as you race towards the finish line, your body slick with sweat.

The crowd cheers you on, shouting encouragement as you race past them. You can hear the other pony girls behind you, their carts rattling and bouncing as they try to catch up.

In the end, it's a close race, but you manage to cross the finish line first. You pant and gasp for breath, feeling a sense of pride and accomplishment.

But as you're led back to your stall, you realize that this is your life now. You're a pony girl, a slave to Doctor Jade's twisted experiments. And there's no escape from this place.
