'A pony! I want a pony!' — your Owner says, making an adorable begging face that would make anyone's heart melt. You shift from foot to foot nervously. A proper horse simply wouldn't fit in here!
The twins remove all clothing from the guy, moving with surgical precision, as if they were servants their whole life. He is left stark naked. You look at his penis and shudder in embarrassment. Why did they undress him?
It becomes clear very soon. Shawn's skin gradually gets darker and darker, taking on a rubbery sheen. His limbs contort and twitch: arms get thinner while legs elongate. The guy's hips expand dramatically, giving him a feminine waist. His cock retracts into his body, making the poor fellow scream:
'PLEASE, NO I DON'T WANT-'
Rimi stuffs a ball gag in his mouth, not letting him disturb Little Mistress with silly shrieks. She fastens the gag with several rubber straps and buckles. Shawn's eyes widen in horror and you see that they actually got bigger and more feminine, complete with eyelashes and mascara. His jawbone cracks and reforms, making his face softer. His skin is devoid of acne now, shining with newfound feminity. Rimi grabs the guy's hair and tugs on it as if it's a bunch of rubber bands. Surprisingly, the hair does elongate and Rimi ties it in a ponytail with a clip.
Shawn's skin is now pitch black and shiny below his neck. It's a latex catsuit!
Little Mistress seems satisfied with how the transformation is going. She claps her hands happily.
'Now, get her ready!'
Rini pulls out a big box seemingly out of nowhere, much like the ball gag. She opens it and starts putting various bondage items on pony's sexy body while Rimi holds the victim pinned down.
First come the plastic hooves. They are put on the girl's palms and feet and locked place with cuffs. Then a set of buckles and straps is fastened on the rubber-clad body. The twins turn the girl around. She's not struggling anymore, having accepted her fate as a plaything. Finally, a small saddle is attached to the buckles.
Two egg vibrators are taken out of the box. The twins attach them to the girl's breasts. Long wires end with pink remotes.
Your owner smiles.
'I wanna ride my pony, Sephi~'
You can't deny your little princess's request, even though you fear the girl's back might snap. You help your Mistress get on the 'horse', holding the long rubber dress's tail. Rimi and Rini hand Little Mistress the remotes which seem to serve as makeshift reins.
'Let's go!'
The girl starts crawling reluctantly. Her plump shiny ass is arched upwards, and Little Mistress is not exactly very tall, making the experience a bit more authentic as the Owner's feet are actually off the floor.
'Now, to the right!'
She presses a button on the right remote, making the egg vibrate and stimulate the pony's nipple. She moans in pleasure and nearly falls, but manages to keep her balance and turn right.
Your Owner is clearly having a lot of fun. She laughs cheerfully, making the horse go left, right, back and around.
The pony girl is constantly on the verge of orgasm, but those vibrator pulses just aren't enough. With every jolt of pleasure she loses a tiny bit of her conscience.
'I... am a pony... I live to serve my Mistress. No, this isn't right. Who am I? Sh... Shawna... Sherry?' — she thinks, confused.
You spend a good hour riding around the house before finally stopping and letting the pony rest.
