You walked up the road to Fluttershy’s cottage. You often enjoyed helping her out, she was a sweet, if somewhat shy mare. You’d been assisting her for the past week or so and you were pretty sure she was beginning to open up. It made you happy to see that...it also helped that she was pretty cute little mare. But of course you wouldn’t even dream of taking advantage, but...if she happened to develop a fondness for you, you would exactly complain.
You came up to her large wooden door and knocked twice, waiting for a bit. After a moment you heard her small voice calling from the yard.
“Um...hello? Is that you? If not...Um...I’m sorry...but if it is...you can come in! The gates open, I’m in the backyard.”
You nodded to yourself, heading back to the little wooden fence, it swung open with a slight creak as you looked around .
“It’s me! I’ve come to help out with th-”
Your voice dies in your throat. Fluttershy is over by the chicken coops. She’s facing away from you, fiddling with the incubator. You can’t help but stare as this gives you a perfect, unimpeded view of her ass. The normally slightly chubby cheeks are tensed as she reaches far into the coop, one leg up in the air for balance, as it moves her ass shifts with it. Fluttershy wasn’t the fittest pony in the universe, but her work with animals kept her from getting fat. Still she had a bit of chub around her flank, you watch as it jiggles underneath that long pink tail which is raised as she strained to reach as far as possible. You’re not even sure she realizes how high it is and the show you’re getting as a result. You can feel your cheeks burning as you watch hers, the pale yellow flesh bouncing delightfully as she works on something inside.

“Got it,” she says, her soft voice happy with accomplishment. She backs out of the coop, the way her hips have to move to accomplish this makes your eyes widen. As her flowing pink mane comes free you try to avert your gaze in time, but you can tell by the way she suddenly reddens that she noticed you ogling her.
“Oh-oh my...” she says softly.
You quickly raised your hooves. “Oh! Nonononono! Fluttershy, I was not looking at your...well...I mean...I was...the chicken coop...and...”
She quickly turns around and sits on her rump. Now that she’s not stretching or straining the bit of chub in her figure is more obvious. Her butt smashed against the ground a little pressing against the grass, you can’t help yourself, your eyes follow it down. You can see both sets of cheeks growing redder.
“I...um...” she eeps. trying to shuffle back towards the coop.
You sigh. “I’m sorry.” You look up at her, honestly apologetic.
She looks off to the left, not meeting your eye, looking...ashamed?
You tilt your head. “....What’s wrong? Listen Fluttershy I really am sorry...”
She shook her head, her face scrunched up in shame. “I-it’s not you...I...I have a fat flank...how could you not stare...I’m just...a Buttershy.”
You paused, frowning. “Buttershy?” You trotted carefully over sitting down next to her.
She looked away, but didn’t move. “It’s...what some mares at the spa called me...I dropped my bits on the ground when I tried to pay...and...and when I bent over to get them that’s what they called me....Buttershy. A-a fat flank!” She sniffed.

You look at her for a moment before wrapping a hoof around her. “Well...don’t listen to those mares, they’re crazy.”
Fluttershy sniffed again. “No they’re not...I’m a Buttershy...an ugly...worthless...Buttershy.”
You hugged her close. “No...no...I don’t think you’re ugly...I think you’re beautiful...”
She sniffled. “No you don’t...you were staring at it...when people see me, that’s all they notice...”
It was your turn to blush. You fidgeted awkwardly. “Well...I wasn’t staring at your flank because its fat...I...I was staring at it because I...Like it.”
She paused, turning to look at you, her face flushing. “...Like it?”
You nodded sheepishly. “I...kind of have a thing for...well...rears, and I don’t think yours makes you ugly...”
Fluttershy was red as a strawberry. She looked down at her rump then up at you. “Um...really?”
You nodded, embarrassed.
“Well...thank you.” she said softly. She scooted a bit closer, suddenly her rump was touching yours, the warm skin rubbing against your thigh. You stiffened noticeably. She tilted her head. “Um...you know...I don’t always need as much help as I...well..as I say around here.”
You blinked. “You...don’t?”
She shook her head, looking off to the left. “I...really just...kind of like having you around...and..um...I’ve been hoping...we...could...um...”
You look at her...she can’t honestly be asking what you think she is.
Suddenly she gets up, bending her forlegs, and you find your vision filled by soft yellow assflesh. Fluttershy squeaked embarrassed.
“Show me how much y-ou like my flank!” she yelled.

You sputter and choke at the request. She...she can’t possibly be... But as you watch wide eyed, her ass shifts before you, her cheeks look so...soft, just like the rest of her...her personality, her voice, her mane, even her silky tail as it lifts aside to give you a better view. There’s nothing about her you don’t want to hold tight and caress, but at the moment only one thing has your attention.
“A-are you sure about this?” you asked, biting your lip.
You can hardly see any of her, past that ample rump, but you make out her nodding. She’s tense, waiting, you can feel her need, this request has been building up in her for a while. She needs attention, to be reassured.
Welp. Who are you to deny her that?
You close your eyes and take a breath. “I’ll start off soft.” you said quietly. You bend forwards and press your lips to her left cheek, the flesh giving slightly under you lips, deforming as the curve of it greets your nose. She’s ever so slightly sweaty from working outside with the animals, her natural scent mixed with a hint of sod and animal feed. They’re just as soft as they looked, pressing warmly back against your lips. You hear an ‘eep’ at your kiss, before she exhales lightly.

You can’t help but smile at that, she’s adorable...and so is her ass.
You start in earnest, lifting your hooves you trace them tantalizingly up her legs and across her thighs, languishing on her cutiemarks for a moment. You feel her shudder at your teasing, tiny high sounds escaping from her every so often. Then you finally reach her rear. You start off slowly, caressing lovely at the curves of her cheeks, massaging and kneading softly. The flesh bends and jiggles under your light touch like a light airy bubble. It reddens at your caresses, her whole body seeming to blush. You can feel your body responding. She’s so soft...
You really couldn’t stop now if you wanted to. You lean downwards, your face meeting her cheeks and letting them surround you in her softness. You shake your head back and forth for a moment in a tease, motorboating. She makes adorable sounds of surprise and pleasure at that.
You stop teasing, and open your mouth, letting your long tongue snake out against her cheeks dragging itself lovingly over the soft globes of flesh, making them shiny with saliva. Her taste fills your mouth and you revel in every second as her breath grows quicker, little squeaks and eeps more frequent.

You get closer and closer and finally your tongue decends into her crack, reaching deeply as it slithers between her cheeks as they conform around your muzzle. Her sounds are muffled by her ample rump, but you can hear them all the same as they grow louder. You reach your prize, your tongue licks teasingly at her anus teasing at the small tight hole before delving in deep, pushing in and out in long, loving strokes. She begins to squirm, her ass shaking around your head. You can feel your member throbbing, almost hurting with need. You pause for a moment...is she ready for this?
You look up at her, she’s looking back at you, fidgeting needily.
“C-can I.” You begin, hardly able to speak.
Her eyes widen with comprehension. For a moment you fear you’ve scared her away and that everything will stop. But as quick as that though flashes across your mind, her ass lowers away from your face, and meets your member. She sets her cheeks right on the tip, looking back at you shyly.
The sensation of those buns on your throbbing length almost drive you mad. But you hold on, she’s new...you’ll go easy.

You wrap your hooves around her middle, and slowly ease her downwards your saliva letting you slide into that oh so tight hole easily. Both of you gasp at the sensation. Fluttershy squirms and wiggles with pleasure, her squeaks becoming long moans as you slowly work your way back out. Then in. And out. And in. And out. The tightness sliding along your length faster. The sensation of her thick supple yellow cheeks slapping against your groin, around your member...it’s too much.
The two of you cry out, and you fill her, continually with your seed, cumming long and hard before the two of you slump to the ground, your length giving a few final throbs and spurts as it slides free.
She snuggles up to you, breathing too hard, or perhaps too shy to say anything. That’s alright, you comfort her, wrapping your arms around her and laying there in the warm grass under the sun. You smile at her.
“I like you just the way you are.”
End.
