Make Womb for the new Queen

"Your will is strong, princess; but unfortunately it's not strong enough," Starlight says as she stares more intensely into Celestia's eyes.

"W-why are you doing this?" Celestia asked, straining to keep control of her mind as the rebellious unicorn forced herself into her mind.

Starlight laughed as she approached Celestia and stroked her cheek, smiling devilishly. "Because, I know I can do better than you or your overly dramatic sister," Starlight answered.

"LEAVE LUNA OUT OF THIS!" Celestia yelled, bringing out her royal Canterlot voice only for Starlight to intense her gaze again.

"SILENCE!" Starlight yelled back as the hypnotism took full control.

"Yes, Starlight Glimmer," Celestia replied, now fully in Starlight's hypnotic grasp.

"Good, now as I was saying, look at the events that have transpired during your rule, your own sister attempted mutiny so you sealed her away in the moon, unfortunately, she returned, but once her evil side was dispelled, you welcomed her back with no consequence dished out to her," Starlight said as she trotted over to Celestia's throne and plopped down on it.

"Then there was Discord who you had placed as a decoration in your private garden, I have to applause you for something that morbid, but he returned and your excuse for not helping was your connection to the elements was cut," The purple unicorn contained as she got up.

"Chrysalis, you were defeated easily and Sombra you did nothing at all," Starlight continued getting more and more fumed up.

"But those all pale in comparison to when Tirek escaped Tartarus, you along with Luna and Cadence, instead of banning together to fight him decided to hide your magic," Starlight closed her eyes and breathed out.

"I used to think Cutie marks were my problem, turns out that my problem was with how you run things. A ruler must be willing to make a decision that may not be ethical if it means saving their people, so now, I relieve you and Luna of your princess duties," Starlight said as she turned around and hiked up her tail, revealing her dripping wet marehood.

"Crawl in my pussy, retreat into my womb so I can assimilate your powers," Starlight commands.

"Yes, Starlight Glimmer," Celestia said as she approached Starlight and kneeled her head. Celestia shoves her horn into Starlight's pussy, causing her to moan in pleasure.

"Good princess," Starlight cooed as she shivered at the sensation. Starlight started gyrating her hips to help Celestia along, slowly sliding her deeper into her cervix and up into her womb.

Starlight's tongue rolls out as her pussy gets wetter as Celestia slides into her, causing her to shake and her knees to weaken. "Don't worry, princess, I won't wipe you from existence, but you will have no memory of this whatsoever," Starlight says as she clenched her vaginal muscles to pull Celestia in deeper.

Starlight sighs, feeling triumphant as she looks behind her to see Celestia's flanks still sticking out of her love tunnel. She smiles to herself as she starts to think about how to best handle Luna.

Smiling to herself, Starlight decides to handle Luna the same way she did Celestia. Upon making the decision, using all her strength Starlight clenches her vaginal muscles and brings Celestia into her womb.

"There we go, all tucked away into my womb, soon to be my child," Starlight said as she snickered, Celestia causing a noticeable pregnant bulge in Starlight.

As Starlight rested on the throne, Twilight came barging in. "Celestia, I thought I'd come to visit and we……." Twilight stopped mid-sentence as she saw Starlight on the throne, an evil smirk on her face.

"Hello, Twilight," Starlight said as she ignited her horn, and a blinding flash blinded Twilight as Starlight closed her eyes.
