However, Celestia fared no better, she howled as her horn flooded Starlight's baby factory with liquid magic to the point where her belly almost began to grow, it was lucky that liquid magic couldn't fertilize eggs either. Starlight groaned in frustration while her body absorbed the magic "You two are completely and utterly useless! Twilight!"

Twilight rushed over and said "Yes Miss?"

Starlight bestowed Twilight with the same gift she had just given Cadance and simply said "Fuck her".

Twilight and Cadance approached Luna and Celestia respectively, as soon as Celestia had pulled her horn out of Starlight she mounted her. Cadance turned Luna around to face her using her magic, clearly deciding to take her mouth, Twilight it seemed was trying to gain entrance to Celestia's ass.

Before they started, Starlight cast the permanent heat spell on Celestia, then set about masturbating as she watched them both get their holes fucked, rubbing her hoof against her moist pussy. Cadance wasn't exactly a gentle lover, she pretty much rammed her cock in Luna's mouth and began fucking with wild abandon, Luna gagging, hacking and coughing the entire time. Twilight was more methodical, she repeatedly pressed the tip of her cock against Celestia's pristine pony princess pucker until it finally allowed her cock entry.

Twilight slid her cock into Celestia's ass, making her whine like the bitch she was. When Twilight had gotten herself all the way inside, with her hips pushing her against her majestic butt cheeks, she began pumping herself in and out at a measured and steady pace. Cadance on the other hand was panting and sweating, mercilessly thrusting away at Luna's mouth to a point where her eyes were watering and black mascara stained tears ran down her face as she was forced to accept the tool down her throat.

Several minutes passed, with Cadance enjoying the sloppy wetness of Luna's mouth while Twilight was in the same state enjoying the warmth and tightness of Celestia's ass. Starlight was still rubbing her hoof against her pussy, desperate to reach her climax. All of a sudden Cadance cried out as she came, Luna obediently swallowed her cum but struggled to keep up, resulting in most of the cum dribbling down her chin and onto the floor. Twilight made the same noise seconds later as she painted Celestia's insides white with her jizz. It was those noises that finally allowed Starlight to orgasm, squirted juices all over her hoof.

They were all exhausted, Twilight and Cadance joined their princess partners on the floor. Starlight looked at the ponies she had conquered, it was done, she could now rule Equestria, with these four princesses as her bitches, she could even whore them out to the public. She could do anything she wanted, she was the ruler of Equestria.
