For a solid month Celestia has been used as a cum dump by all the monster women. So that all of their cum would mix and merge together inside of her, their powers and DNA something that Sunset had mention as the building blocks of every living creature, all becoming one inside of her. Which would form into a birthing pod inside of her that she will give birth to, once all the monster women are done with her.

Right now Celestia couldn’t move her body thanks to being completely exhausted and drained from all the non stop fucking. Sunset had also been sucking on her milk filled breasts that are also filled with her magic, which Sunset fed upon so that her magic would become hers. And that once Celestia gave birth to the birthing pod, Sunset would need all the magic she’s been draining for her transformation.

Yua the spider woman moved over Celestia’s cum covered prone form. Deftly using her taloned appendages, Celestia’s legs were opened. Yua’s 19 inch cock moved directly to the entrance of her well used pussy. Celestia had been introduced to all manner and different types of cocks, depending on what kind of monster woman was fucking her. One type of monster girl has a cock with more than one head like an echidna, some have more then one cock like the snake monsters, some like the dolphin monster girls have a prehensile penis, meaning it can swivel, grab and grope, much like a hand. Some of the bird types along with the pig ones have corkscrew-shaped cocks. The cat girls have barbed cocks while there are many cocks with knots like the dog types that lock them in once they cum. The turtle types have horrifying large and long cocks. As for Yua her cock has knobs or knuckles on her cock’s length. Every 4 or 5 or so inches length, there was an enlargement in the girth of the cock, looking like a series of knots tied in a rope. (1)

The softball sized head was slippery with pre-cum. It pressed into the mouth of her feminine canal. Her tortured rape screams delighted the other monster women watching the show. All of them have only been using her cunt as that’s where they needed to cum so that their daughter could be reborn.

Celestia was rolling her head from side to side in pain, thus the monster girls on all sides were able to enjoy her anguish. Her rapist began humping greedily in and out. The alicorns pussy was so tight that it delighted the spider monster sensitive penis crown each backstroke. Thanks to the monsters healing her after each rape so that she wouldn’t die or become too loose. Then the sadistic forward thrust forcing the high pitched scream Celestia’s throat.

Yua continued fucking Celestia while the others including Sunset watched enjoying the suffering from her mother. Yua drove herself deeper, so that the first large knob on her cock force itself into Celestia. The stretching her pussy to accommodate the spider cock head was terrible enough, but she thought that pain over once it was inside. Now there was this knob, slightly larger than the cock head. Its rock hardness stretched her tortured pussy open again and again with each stroke. As Yua began pounding into her deeper, Celestia was shaking her head spastically and bellowing her suffering. She was no longer able to regulate her breathing, alternating between desperate intakes of air and hyper ventilating. The second knob on its cock was at 10 inches length, and this began to pound into Celestia’s abused pussy. Now each in and out fuck was causing her double the stretching pain. Yua increased tempo, driving down onto Celestia underneath her.

Yua used her spider legs to latched onto the floor to anchor herself. Then she thrust into Celestia faster and harder then she had before when she was using her normal legs. As the spider woman lowered herself down onto Celestia, Yua wraps her normal arms and legs around her. Her screams became muffled echoes, as Yua locks her lips on hers as she used her powerful spider legs to thrust her cock stronger then she could with her normal legs.

Sensational pleasure coursed through Yua as she drove her third knot inside Celestia. Her climax brought forth a sudden violent ejaculation. So forcibly did her thick hot sperm erupt into Celestia, that it would have launched her body off the dick. Except that the spiders cock head had expanded by half its already huge size, to bask in its orgasm and that Yua had her normal limbs wrap around her.

The hot wet blast of cum filling Celestia’s pussy instantly. With no outlet for the liquid, it was forced deeper into her internals. When Celestia’s womb was filled with cum, the liquid pushed out in all directions. Celestia watched in total agony as her belly began to expand outward from the liquid pressure, like all the other times it has happen to her already from all the other rapes. Still Yua was firing gallons of cum into her. The pain of her insides bursting was more than Celestia could take. Her pupils rolled back into her eyes so that only the whites were showing, and her body went into shocked convulsions.

Sunset watched as Celestia’s belly became big with all the cum that Yua pumped into her. Yua rested on top of Celestia enjoying as her belly grew big as she drains her balls into her. Then once she taps off with her cock keeping all of her cum inside, she just basked in the after glow as she rested on Celestia.

Then the cum began to be absorbed by the Goddess Vase spell used on Celestia. Adding Yua's cum to mixture of cum from all the others who had raped Celestia. Devouring, absorbing and merging together to create the prefect sperm that will create the birthing pod for Sunset's rebirth.

"Enough," Nightmare Moon said stepping up next to the pair, with her still dripping cock hanging over and dripping cum on Celestia's face. "We all have cum enough times in her, we all done it at least 10 times each at this point. It's time for Sunset's rebirth as all of our daughters."

"Yes enough with the fun," Yua said pulling out of Celestia.

"Now sister it's time to give birth," Moon said as she activates the spell causing Celestia to scream as she gave birth.

Popping out of her cunt came out an egg like sack of flesh, that has four flower like flesh petals that made the egg shape. Which began to grow in size as it absorbed the magic around it, not stopping till it became big enough to hold a body inside of it. The egg sack once fully grown the petals open up awaiting for something to enter it. Where it would like a cocoon would break down the being inside of it and remake it into a new being, using all the different DNA that it has absorbed to do it. Making the new being into the child of all the different donors that had cum into the female used as the goddess vase and the female as well. (2)

"Now, I can be what, I was always meant to be," Sunset said as she was carried to the birthing pod by her sister Alice, who is the only one who hadn't cum into Celestia. Thanks to Sunset talking her out of it as they would be real sisters thanks to Alice's mom the older Alice raping Celestia already. And Sunset really didn't want to have Alice as her sister and mother as that's too inbred for her liking. Which she spent her time raping Twilight and her group to pass the time.

"It will take you a couple of months," Alice said as she lowers her sister into the open pod.

"Than you all just have to wait for me than. Have fun with mom and Twilight's gang," Sunset said as the birthing pod closed around her.

"Don't worry we will," Alice said as the birthing pod sealed shut and began to break down and rebuild Sunset.

"Sunset," Celestia gasp out as Sunset once she comes out will not be the same.

"You really should had treated Sunset better when you had the chance sister. You never even wrote to her as you had the journal to contact her. But seeing how she will be not my niece but my daughter like everyone else here but for young Alice. We can treat her as she should had been treated. And you have no one but yourself to blame for this," Moon said to Celestia.

"I know," Celestia said weeping for ruining the best thing she had in her long life.

Author's Note

1 - Seeing how many of the monsters are based on real life animals they would have cocks like their real life counterparts.

2 - Like the eggs in the Alien films.
