A certain batpony shestallion ends up becoming Princess Celestia's cumdump, before being turned into a submissive, horny cow. Amaranthine certainly isn't going to see that heavy, mottled horsecock swaying between Celestia's legs coming, but by the end of the day she'll happily accept her new role.

This story is a commission for Gold4Tune, and involves his delightful bat pony slut OC named Amaranthine. She's got a dick and acts tough, but deep down she's really a submissive cutie, and much better off becoming Princess Celestia's devoted harem toy.

First chapter may contain: Ridiculous, obscene amounts of semen, gasp! As well as lots and lots of oral, worship of Celestia's massive cock, and Amaranthine being turned from a proud, dominant mare into Celestia's drooling, submissive pet.

The second chapter contains better pacing and flow, as smut heavy as it is. Amaranthine gets femdommed and relentlessly milked for her jizz by Celestia's own broodmares, before they turn her into a docile, mooing slut.
