In the dimly lit dungeon, the ponygirl is adorned with a gleaming bit gag and a tight corset, her hair flowing like a mane. Her master, a stern stable master, polishes his riding crop, ready for another round of training. With a snap of the crop, she's off, hooves clattering on the hardwood floor, her body swaying in a rhythmic dance of submission. The master's voice echoes, "Faster, my pony, show me your spirit." She responds, her eyes gleaming with sweat and desire, lost in the haze of her ponyhead, yearning for the next command.
