Just a Quick little story to celebrate the eclipse. Incest, Yuri, Magic!Impregnation, Waterworks, Anthro.

Nightmare Moon ran, darkness around her covering the light as she chased her older sister DayBreaker. I will be the one to win this race! suddenly the older sibling stopped and stuck her foot out knocking NightMare on her back. She groaned as DayBreaker crawled on top of her sitting on her legs and resting her Ivory white breasts on NightMare Moon's face.

"Sister what are you doing?! Mhbbhkjdwa!" NightMare's protests were muffled by the massive mamories of flesh as her older sister straddled her. "Shhhhhhhh Shhhhhh... It's time to make a new eclipse sister. Just us in an empty void, Isn't this a romantic way for me to claim my property?~" DayBreaker whispered into NightMare's ear rubbing her thigh between the darker pony's legs. The ebony mare moaned against her breasts as Daybreaker slipped her fingers into her hole. "Mmmmm~ You're dripping wet sister~ admit it, you wanted big sis to finally claim you~" NightMare moon whined as the fingers dug in harshly into her hole, she started idly sucking on the breasts that were in her face making her older sister moan.

"That's it pet~ that's it~ Big sis is gonna take good care of you~" NightMare moaned as DayBreaker cast a Dgirl spell on herself and slid into the black mare's leaking pussy. Nightmare sucked with more vigor on the two breasts in her mouth moaning louder as DayBreaker picked up her pace, smiling when she saw blood mixed with her sister's leak. "Yesssss~ You're doing wonderful~ You naughty naughty little moon~" NightMare moon whined at her sisters teasing words biting hard on her breasts to leave hickeys, this only gave DayBreaker a reason to get rougher, Rearranging so that NightMare was now riding her she grabbed her little sisters hips and slammed into the younger mare. Breaking through her cervix and tickling the back of her womb.

"OH YES YOU'RE SO TIGHT!" DayBreaker yelled pounding nonstop into NightMare who screamed from the severe pleasure.
"W-w-why doesn't this hurt!" She screamed as she was pounded with enough force to shred anyone else in half.
"Sweet sister I'm offended. You really think I'd hurt you on our special day? I cast a spell that turned all pain into pleasure before we even started." DayBreaker informed the now writing younger mare, savoring the way her sister's pussy clenched around her new cock. NightMare wrapped her arms tightly around her older sister's neck as her virgin pussy swallowed the Dgirl cock hungrily. after ten minutes of struggling NightMare embraced her sister and kissed her while she came, The loving ministrations of her sister's tongue in her mouth making DayBreaker cum directly into her little sister's womb.

"I'm so glad You've decided to embrace your new life as my bride Moony~" Daybreaker grinned giving her sister another heated kiss. "mmmm~ Big sister's cock...~" NightMare replied sleepily. Tired out from the rough bucking. Daybreaker leaned in and gave her a gentle loving kiss this time, NightMare moaned into the kiss as hot yellow liquid poured into her cunt from her sister's cock.
"Now no one can take you from me~" Daybreaker whispered holding her sister closely.

The world around them morphed into a luxurious bedroom as the role play ended. 'DayBreaker' and 'NightMare Moon' being revealed to be the royal sisters.
"Was the claiming thing too much?" Celestia asked in her usual motherly tone.
"S-shutuwpsis... b-brain s-still fried..." Luna mumbled to her sister sleeping on top of the ivory alicorn, Celestia chuckled wrapping wings around her little sister.
"Alright. Sleep well my bride."
