Amy and Sarah become ponies

Following the auction Amy and Sarah were presented with the crude reality that from on they will continue their lives as pony slaves. Like all zetan ponies they were equipped with a giant bite gag, a ruanite harness, a corset, an armbinder, pony boots, and of course two giant plugs in their openings that are kept in place by the harness.

Thanks to the giant plugs they were constantly horny. But they also read on the StarNet that ponies rarely get an orgasm. If their owner permits them any. And indeed, the past week they were not permitted an orgasm. They had to spend the better part of the day on the sun, so their skin and bodies would get accustomed to the heat. And that was it. Just standing there. Looking at each other and thinking about the days where they could access their private parts so freely it was like breathing the air.
