Changing a Changeling

"Are you sure we should be doing this in the changing room Glimmy? It feels a little... naughty" said Chryssie, she was wearing the outfit, had applied the make up, had the lead on her collar, the only thing left to use was the butt plug.

Glimmer said "Will you relax Chryssie? This is Ann Summares! This kind of thing probably happens all the time, at least we are not fucking in here. Besides, you are a naughty mare aren't you?"

Chryssie blushed and went "Y-yeah..."

Starlight glared at her "Fucking say it"

With a whimper, Chryssie obeyed and said "I-I'm a n-naughty mare..."

"Good girl" said Starlight, shortly before putting the butt plug in her mouth and lubricating it with her saliva, once she popped it out of her mouth she said "This is going in your ass, you're going to keep it in there until I say so, do you understand?"

Chryssie blushed even harder "But...but Glimmy..."

Starlight glared at her even harder and through gritted teeth said "I'm not fucking asking bitch".

Chryssie gulped and turned around, raising her tail up and spreading her back legs a little, giving Starlight access to her sweet tight little asshole. Starlight moved forward and gave one long firm lick against Chryssie's asshole to prepare it for the impending penetration, as she pressed the tip of the butt plug up against Chryssie's back entrance she felt the resistance it was gonna put up.

Starlight decided the best way to go about this would be to just push harder and harder and harder until it was crammed into her ass, so that's just what she did. Initially, Starlight struggled so much getting it in that she wondered if it would even fit inside her at all, but using all the strength she could muster, Chryssie's asshole stretched open and allowed the butt plug to become buried in her bottom. Starlight stood back as Chryssie turned back around and struck a pose. That was when something hit her, Chryssie was actually attractive.

"Wow Chryssie..." said Starlight, slightly breathless with her pussy moistening "You are... so fucking sexy".

Chryssie smiled, blushing again "Thank you Glimmy, I certainly feel sexy..."

Starlight felt somewhat embarrassed as she felt her pussy winking, then again, she had taken it this far. She might as well go the whole hog. Starlight took hold of the lead in her magic and said "Come on, let's go back to the castle, I can show you my room...". Once again as the two of them walked through town, every pony was giving them a whole mix of different reactions, shock, outrage, confusion, a smug "I knew it" look, some ponies even noticed Starlight's very obvious wet and winking pussy as well as the butt plug nestled firmly in Chryssie's ass. They all knew what was going on there, they were going somewhere to fuck. They were right.

Starlight tugged on Chryssie's lead, she was getting impatient, the sooner they were in her room the sooner they could stop holding themselves back. They both burst into the castle and made an immediate bee line for Starlight's bedroom. When they got in there, Starlight and Chryssie slowed down a bit, Starlight took the lead off of Chryssie's collar and set it aside.

"So..." said Starlight "This is my room"

Chryssie looked around before saying "It's nice..."

Starlight nodded "Yeah..."

There was a brief silence, the air was still as they gazed into each others eyes. Then they practically threw themselves at each other as they engaged in a violently passionate kiss.
