>"Hey Tulip isn't your mom a bit...fat?"
>Your ears twitch
>"I dunno Velour but look at it...it's so..."
>"I am...I can't tear my eyes away from it"
>"Me neither Velour, it's like it's...hypnotic"
>"Yeah and it's weird how it's al gathered up in there instead of you know, everywhere"
>You frown and look back at Tulip and Velour
"What are you two whispering about?"
>They tear their eyes off of your behind and answer with "nothing" before exiting the scene
>You sigh and look at your butt, it kind of looks like it's bigger, you guess? You haven't really been paying attention to its size...
>But it is true you've been working out a lot less, and Midnight Delight likes to bake you and Tulip sweets so you've been snacking a bunch
>But it can't be that big, those two must have been just pulling your wing
>You keep walking towards home, now suddenly conscious of your thighs and buttocks rubbing up against one another as you walk
>And completely oblivious to a few zebra's biting their lip and making groping motions and silent screeches and woops as they see you go by and flail around
>After reaching your home you go to the big mirror and take a look at your butt
>And you cringe
"Oh wow, how?"
>It's huge! And it's all in your buttocks and thighs, your tummy has not been bulging out much nor has fat stored up in any other parts of your body, it's just your butts and thighs, no wonder you have not noticed...
>You shift your weight and your booty jiggles, making your eyes shot open wide
>What happened to your perky sporty butt?
>Well it's still surprisingly perky, thankfully no fat hanging ass and no orange peel skin, but it's still at least twice of not three times the size of your butt the previous time you were paying attention to it
>you give your hips a shake, and then push yoru butt out and pres your hind hooves together
>And then you hop up and down a little on them, making your buttocks and thighs clap against one another
>You stop doing that and stand up to your hind hooves and back up against the mirror, your butt squishing up against it much earlier than any of your back touches it
>In fact you have to lean backwards some to even get your upper back to touch against the mirror while your butt feels like it might push the mirror through the wall
>Now that you carefully look at yourself, your hips are wider than your shoulders!
>that's kind of hot...
>Your lean back against the mirror and massage your thighs, now as thick as your head if not thicker
"Wow..."
>you lean back down and keep looking at the mirror while walking away from it, the sway of your hips and the movements of your buttocks having become much more noticeable and larger than normally
"C-calm down Daylily, they just look big but they aren't that big..."
>you quickly get some naughty panties from your wardrobe and start slipping them on
"Yeah I can still slip these on easy...and that part is supposed to stretch, they would not have made it stretchy if it was not supposed to stretch!"
>They do squish up your buttocks some...you have to admit it, they're too small for you now
>You hang your head with a frown and start walking, and suddenly they tear, exposing your ass crack
"Oh come on..."
>You frown and then scrunch as relaxing your body out makes your now unclenched buttocks push out and tear the panties up further, your butt bouncing back to its uncaged glory
>What if Midnight Delight thinks you're a fatty now? You need to start working out...
>You grab your butt and pull your cheeks apart, exposing-how has that gotten fatter?
>Even your marehood has grown larger and puffier to match the size of your newfound booty
>You let go and let your cheeks slap back together, and then give your butt a slap
>And then a harder one, wow this new ass can take much more harder punishment, that did not even feel that-
"Hn!"
>You gave yourself a bit too hard of a slap, making your butt and thighs ripple
>"What are you doing Daylily?"
>You stop and quickly whip your head around, finding an amused looking Midnight Delight leaning at the doorway, looking at you
"Midnight!"
>You turn around quickly, making your thighs slap together rather audibly, making you frown
"I've put on weight..."
>She nods and giggles
>"Yeah I've noticed"
>You blush and scrunch as your ears droop down
"I need to start dieting and working out"
>"Or you could just keep going on like this..."
>You look at Midnight surprised
"Do you...want me to be fat?"
>She shakes her head
>"You're not fat, you've just grown yourself a booty, and what a good booty it is~"
"it is?"
>You look at it again as Midnight Delight walks next to you
>"Oh yes, it's so big and soft yet in the proper shape~"
>She snuggles her head against your butt
>"I really like it"
>Suddenly the front door opens and closes and Tulip rushes to you
"What is it Tu-"
>YOu don't get to finish yoru sentence as she suddenly flies to your butt, pushes Midnight away and hugs her hooves as much around it as she can, burying her face into your butt and rubbing up against it, a muffled eeeeeeeee audible from within
"Hey don't swarm around my butt, it's not that great just because it got fat"
>Tulip pulls her head away to breathe and speak
>"Mom it's not fat, it's amazing!"
>Midnight Delight joins her in groping and nipping and even licking your butt
>"It's simply divine~"
>You start to feel weak on your hooves and rather warm at a certain area
"H-hey now you two calm do-oohhhh... ohhnnn~"
>You find yourself resting your front down against the floor while keeping your butt up as you keep your hind hooves standing
"Will you two hornballs stop that I'm gonna...a-ahh...nnhhhh~"
>You suddenly find yourself surrendering your ass to the two, and after some nipping, licking, touching, massaging, slapping caressing, poking brushing plowing and rummaging, and leaving you panting and drenched, you find yourself thinking that having gained a bit weight like this isn't that bad...
>In fact the next evening at breakfast you took the two by surprise by wearing some booty emphasizing clothing that you picked up at your early evening post run, now noticing how much attention your butt was getting from random ponies
>You do feel a bit bad at how one earth pony stallion got into a fight with his petite marefriend after being caught ogling at you as you were leaning down and going through your bag
>And now you carry your somewhat fat ass with pride, instead of worrying about loosing it right away
>But you still pay a bit more attention to what you eat, you don't want to go from big butt battie to a fat battie, even if the two would probably not even mind if that happened, judging how much they were raving about your softness and cushion-likeness while entranced by your butt
>But you have to admit, with this brand new outlook on things, it's making you beam with pride as you look how it spreads out against the bench you're sitting on while sipping your boxed juice as the last rays of the sun are dispreading into the horizon, the booty shorts in your mailmare bag waiting for you to put them on and make the "morning" of Tulip and Midnight extra delightful
>Why are those zebra's over there saying dayum a lot while glancing at you?
>after remembering all that as you sit at the breakfast table, your butt pleasantly constricted in your booty shorts you realize why and blush
>If Sneak, Lockpick and Butterknife saw you now...well they'd probably instantly beg for a threeway or something
>that or just stare and shout at it incoherently
>You hop off of the chair as the doorbell rings and find Peach Screech and Scratchy Velour behind it
You turn around and lead them in, and pretend you're not hearing the gasps and gulps behind you as you walk them to the kitchen to get a few snacks before playing with Tulip
>And to not scrunch too hard as Midnight Delight decides to suddenly motorboat your butt as the three have made their way to Tulips room and telling her to calm down while she looks at you like a horny teenager barely able to contain her hormones
>Mo butt, mo problems
