Monarch Manipulation

Starlight sighed as she bottomed out in Cadance's pussy and held herself there, enjoying the warmth and comfort of a willing pussy around her cock. Twilight had gotten her lips around Cadance's horn and began taking it further into her mouth, Starlight was surprised to see that Twilight was actually managing to deep-throat the thing until her lips were planted firmly against her forehead, impressive considering she not only had to account for gag reflex but also for the angle of her throat. Starlight decided she had been still for long enough, it was time to fuck this bitch, she pulled her cock almost all the way out before sinking it back in. It felt fucking amazing. She repeated this pattern a couple more times until she had acclimatized to being the male in the situation for once, then began thrusting in earnest, her full balls slapping against Cadance's thighs.

Twilight on the other end was sucking off Cadance's horn like she had been doing it for years, her horn ministrations were practically expert as she licked and sucked from tip to base. Cadance wasn't going to last long at this rate. Alas, being that Starlight had never felt the pleasure of fucking a mare with a real penis, she was woefully unprepared and didn't last as long as she would have liked. She groaned and tightened her grip on Cadance's waist as she shot her very first load, thick and virile, directly into the princess pussy she was fucking. Cadance enjoyed the feeling of a huge amount of cum being deposited into her fuck hole, but didn't get to an orgasm herself, which left her poor wanting pussy unsatisfied.

As Starlight pulled out and dismounted, breathing heavily, she made up for her lack of dick experience by leaning down and shoving her horn into Cadance's pussy. Cadance gasped as she felt Starlight ignite her horn, the magic enveloped her pussy and with a quick burst of magic she screamed as an unexpected full orgasm rippled through her body, soaking Starlight's head with her fluids. Almost immediately after, Cadance couldn't hold back the pleasure her horn was feeling and just as Twilight was back at the tip, liquid magic burst out from her horn and into Twilight's mouth. Remembering Starlight's orders, she allowed the substance to collect and pool in her cheeks. The liquid itself had the same consistency as water, but the taste was harder to describe, it wasn't unpleasant but it wasn't particularly flavorful either, the closest thing she could equate it to was sugar. It was sweet.

Starlight pulled her horn out of Cadance's quivering pussy, thoroughly exhausted as her dick and now empty cum factories simply vanished to make way for her female genitalia. Seeing Twilight's cheeks slightly ballooned out from the copious amount of liquid magic in her mouth she made her way over to her, Twilight stood still as she allowed Starlight pull her in a kiss, she let the liquid magic flow out of her mouth and into Starlight's, emptying her cheeks to fill hers. When Starlight pulled away she licked her lips and swallowed, again her body absorbed the magic making her even more powerful than she was before. "Right..." said Starlight just as she cast the permanent heat spell on Cadance "Now for the final two princesses, to Canterlot girls!"

As luck would have it, in her continuing effort to maintain the facade of doing friendship lessons because she wanted to be a better pony, Starlight knew there was only one time when Celestia and Luna were both in the same room together. First thing in the morning after Celestia raised the sun. As even more luck would have it, Twilight knew how to sneak into Canterlot undetected just before the sun was raised. Cadance didn't know anything useful, fucking bitch. After reaching the door to the main hall, Starlight said "OK, you girls stay here and knock on the door, when Luna and Celestia open just keep them distracted while I teleport behind them and perform my spell, alright?" They both nodded and knocked on the door.

Starlight hid by the side where she would be hidden from view, Celestia and Luna opened the door to see Twilight and Cadance, but were immediately confused. Twilight was in a schoolgirl costume and Cadance was dressed like a lady of the night, what was going on? Twilight and Cadance both grinned and shouted "Surprise!"

By the point, Starlight had already teleported behind the princesses and as soon as she heard the girls say "surprise" she launched to bolts of magic at the princess, which hit them right in the back of their heads and sent them falling to the floor. A few seconds passed, the princess stood themselves up and then just stood there, they were in the trance and all they needed was the trigger. Starlight grinned and said "Princesses! Hear my voice and listen!"

A burst of light, Celestia and Luna turned to face Starlight before bowing and simultaneously saying "What be your command my love?"

Starlight couldn't wait to see how this played out "Celestia, Luna, you shall each find a costume and make-up that you deem to be seductive and sultry, as such you shall also adopt the appropriate personality that would be attributed to the type of person who would be wearing the clothing you select. Do not be seen." Celestia and Luna nodded before teleporting away. Twilight and Cadance entered the main hall and closed the door behind them, they didn't want anyone interrupting their playtime after all. When Celestia and Luna were back, they both had radically different ideas as to what was considered sexy.

Luna was wearing black fishnet stockings on each of her legs that were held up by a garter belt connected to a black leather corset. For make-up she had black lipstick, mascara and eyeliner with black eye shadow, it was the full goth look. Starlight smirked as she noticed that Luna had seen fit to also insert a black butt plug in her rear just to finish off the look. Luna rolled her eyes and said " M'kay I'm back, so are you gonna like fuck us or what? Just do whatever, I don't care".

At first glance, Celestia was less impressive. She hadn't changed her clothes at all except for one additional item, but in this case less was more. Around her neck Celestia was wearing a red collar with a little gold tag that said "Celestia" on it, she was sitting down on the floor with her forelegs up and panting like an excited puppy, because that's what she was being. She was even wagging her tail from side to side.

Everything had fallen into place, after Starlight absorbed the magical essence of Luna and Celestia, her power would be unmatched and she could take her rightful place as ruler of Equestria. She took a seat on the throne and said "Luna, step forward and jam your fucking horn into my pussy".

Luna started walking forward and said "Fine, whatever. It's not like I got anything better to do anyway". Luna got in front of Starlight and lowered her head, she moved forward and in one smooth motion slid the entirety of her horn into Starlight's pussy, the tip just barely touching the entrance to her womb. Luna stayed there for a few seconds, her eyes were wide and her mouth agape, she refused to move.

Starlight was confused and looked down, why wasn't Luna moving? It wasn't as if she had to order her to do it, the previous instruction was very clear and didn't require specifics, maybe-

Starlight's train of thought was interrupting when Luna let out an extremely loud groan of pleasure as her horn began blasting liquid magic inside Starlight's pussy. This took Starlight quite by surprise, she wasn't expecting to be receiving liquid magic quite that soon, Luna and Celestia had clearly never gotten laid. Starlight had always assumed that the princesses didn't have any biological children because they were barren, which they were, but it seems like nobody had ever fucked them during their reign either. She wasn't intending for any of her sex slaves to become pregnant if she decided to create herself a dick and fuck them anyway, although magic made seed was fertile, it could never impregnate a natural egg. The magical properties of the seed and the natural elements of the egg just didn't mix, magical seed could only fertilize magical eggs and natural seed could only fertilize natural eggs, that's the way it was.

Getting back on track, Starlight s body absorbed the magic as Luna pulled out, whimpering from such a powerful horngasm which left Starlight rather unimpressed. "That was pathetic" she said "Cadance..." Starlight ignited her horn and gave Cadance a fairly large package with balls to match "Come over here and fuck this bitch while Celestia hopefully delivers a better horn fucking". Celestia gulped and brought her horn to Starlight's pussy, she pushed it in, going further and further until her horn breached the barrier of her cervix. Starlight squirmed in slight discomfort as Celestia kept going until it was all in, a good inch of her horn in Starlight's uterus.
