Part four - Resentment for Derpy

Be Anonetta. Your brother gave you his fluffies when he had to go on a business trip to China. They have been a handful, but you love playing with them, they are so much fun and they can TALK! You want more, but you know you can barely handle the two plus the cats you already have.
>(A)How are you today Buttercup?
You talk to your Fluffyshy Buttercup as you give her a bath. She has gotten bigger and bigger and is not able to move at all now. You have to clean the filth off of her, even more than usual since she cannot  move on her own and it all just cakes up. You consulted the internet and even a doctor. He chuckled and informed you she is just pregnant and will pop in another week or so.
>Bwuddacup wan nummies fo babbehs! Need make milkies!
>(A)Ok sweety, after bath time for you and Derpy.
>(D)TBPPBLBLBLBPBPBPBLBLBLBLBB!
------
Its unbelievable how much food she has consumed in the last week. She has doubled in size and keeps growing. The fluff around her teats has receded, but she only has two teats. Your not sure how she will support a litter with only two. She complains that they are always sore because Derpy has been feeding on them. She is powerless to stop Derpy because she is to fat to wobble away or buck her off. Unlike before where Derpy would just nuzzle Buttercup's belly, now that she actually has teats, Derpy finds and feeds as if she were still a foal. This causes tearing because she is not a foal anymore and she is to big and rough.

Be Fluffyshy Buttercup. A Fluffyshy clone with a green streak in your mane.
>Stop Wunt. Milkies fo babbehs! NO WUNT! BWUDDACUP HATE WUNT!
Anonetta rushes into the kitchen to see Derpy is at it again. You are screaming so loud because you are super mad that Derpy is stealing your babies nummies, and it hurts, stressing you out.
>(B)OWIES! Big poopsies mommeh! BIG...
>>TEAR-SPLAT!<<
Be Anonetta.
Buttercup ruptures open in front of your eyes. Buttercup is spilling out foals, blood, fat and other fluids on the kitchen floor. You rush the whole mess to the vet. They manage to save Buttercup and sew her back up, but her body could no longer handle the stress of her extreme weight and size, for a fluffy pony. Blood was no longer flowing properly with her weak heart and both of her hind legs had to be amputated from atrophy. They sit her in a little cart that straps on to her but doesnt block her teats.

Be Fluffyshy Buttercup.
You wake up at home. You are groggy and dont remember what happened. You remember something... OH NOE! You made BIG poopies all over the kitchen floor! Mommy must be upset with you and locked you away!
>Eep! Eep! Hungy! Mommeh!
Whats this?
BBBBAAAABBBBBBEEEHHHSSS!!!!!!!!!
You explode.
Metaphorically speaking of course. You go to move to them but you cant. You are too weak and groggy to move still. They are in a small fluff pile and slowly move over to you and start to nurse but, it hurts a lot. Your teats are very sore and it hurts to feed your babbies. One. Two.. Three?.. Four, that comes after three. Five? Seven. You have seven babbies! Oh no, thats not good. It hurts a lot already and you are feeding only the first two.
>Owiesss!!!!!!
Your outburst stirs Derpy. She gets up yawning from the otherside of your foal fluff pile. Stupid runt. Oh no, shes coming over. She is bigger and easily knocks off the babies that are feeding and starts taking their milk!
>(B)BAD WUNT! Milk fo babbehs! STOP! HEWP! WUNT! MUMMA!
Momma comes running in and removes Derpy but its to late. The milk is gone and only two babbies got any milk, and not enough at that. The rest are now suckling at your dry empty teats causing horrible pain and tearing.
>Hungy! Mommeh! Miwkies!
>(B)Momma no hav mowe fo babbehs.
>But babbeh is good babbeh. Tummy owies! Wan miwk!
All of the babies start crying and chirping for milk.
-----
Its only been a few days, but seams like an eternity for you. You never have enough milk for all your babies, even when Derpy doesnt take it all. They mewl and cry constantly. You are in constant pain and have been unable to sleep. You pass out quite often from sleep deprivation, at least until somefluffy, foal or Derpy, starts suckling on you. Today one of your babies stopped moving. You wobble over to nudge it.
>Pwease move babbeh. Mommeh make miwkies fo you.
The foal does not respond.
>(B)Pwease, Bwuddacup is good mommeh.... good fwuffy...
>(B).... Babbeh... babbeh sweep foweva. No mowe cry. Onwy siwence now.
>(B).... huhuuu huuhuuuhuuuhuuuuuuuuuu.
You quietly sob. After some time, your fluffy brain makes a connection. Less foals means less pain and more milk for the stronger babies...much like when you had babies which made you forget about everything else and only babbies mattered, now pain makes you forget the importance of all babies, overriding genetic programming through delirium. For some reason you gather your babbies and you wobble to the closet in your safe room.
(B)Come on babbehs! Fowwow mummeh!
------
It is the end of the first week, which for you it seams like a lifetime. You dont remember much from the past week because of the horrible pain from your teats being sucked dry and torn all the time and constant sleep deprivation. You just remember dealing with the runt taking all your babbies milk, and momma being nice to you. You are startled awake to feeding time and your two foals feed. You must of had a small litter, only having two foals makes you kinda sad. Momma started putting Derpy outside for most of the day allowing you some rest, and milk left for the foals. Even though there is only two, without constant supervision to keep the runt away, they are still fragile and weak eating only what is left. You wobble to the litterbox after feeding time to poop, and then to the closet. You dont know why you do this now, but you do. Sometimes you mewl quietly, sometimes you sob. Cries from you babies wanting warmth, nummies or to play warm your heart though and you leave to go back to them.
Runt returns... you hate the runt. She babbels and makes wierd noises.
>(D)Derp! thbblblblblbllssss. Pway wif mommeh! Babbehs! Phsppbpbpbpb.
Why does the Wunt get to play with mommeh, and babbies. Wunt takes your babies milk, has fun and you get nothing but pain?
Derpy proceeds to play with your babbies. She is to rough and usually hurts them because they are so weak and fragile. One time you saw her with a foal sticking out of her mouth drooling all over one as it struggled for air. That one's winggies have not worked right since.
>(D)Ppthhbhbpbpbpbp Hungy!
Derpy comes over and steals your babies milk. You dont even fight it anymore as you cant stop her. You are to fat to kick her away so you just lay there and cry from the pain.

End part four, thanks for reading. Link to part five when its done.
