> When you showed up in Equestria, you were initially mistaken for some sort of mutant bear
> To be fair, you had just woken up from a long nap, and were slightly hungover from interdimensional travel
> Your clothes were fried, and you lost most of your body hair in the transit
> You'd have felt a bit like a terminator, but mostly you were grumbling, trying to find some aspirin
> Long story short, you are now Fluttershy's roommate, and everyone is really sorry about the torches and pitchforks, really.
> This morning, you are wearing nothing but an apron as you cook breakfast
> Living with naked ponies has largely desensitized you to nudity, and it's comfortable
> You hear quiet hoofsteps coming down the steps
"Good morning, Fluttershy. Want some breakfast?"
> You glance over your shoulder
> She doesn't meet your eyes, but that's hardly unusual
> "Um, how about some... dessert first?"
> Then she licks her lips
> You have just the thing
"Well, I do have pancakes. With butter and syrup, that's pretty close."
> She frowns, but then reconsiders
> "It'd be a shame to dirty a plate just for this. Why don't I eat off of you instead?"
> Good thinking, one less dish to wash
"Sounds good! Let me just get out of this apron."
> It feels good to lay on the floor, and the pancake is warm
> Fluttershy scoots it a little further down your flat stomach
"Something wrong?"
> Fluttershy looks you straight in the eye
> "Call me mistress. Um, if it's not too much trouble."
"Oh, so your last name is Tress? Funny how it just never came up. Anyways, eat up, Miss Tress!"
> Fluttershy pours the syrup over the pancake, the excess flowing between your legs, gathering where your penis lay against you
> "Oh, I'm so sorry, let me just... clean you up..."
> She lowers her muzzle and laps at your hardening member
"Uh, Fluttershy?"
> She stops immediately, and glares at you
> "I said, call me mistress. Um. In case you don't remember."
"Sorry, Miss Tress. But you don't have to do that, I'll be taking a bath anyways."
> She glances at your sticky length, then sighs
> "I guess I won't then."
> Then Flutte- you mean, Miss Tress brightens up a bit
> You will have to try today her name more often, so you can remember it
> She delicately cuts the pancake into little pieces
> The butterknife edge feels kinda funny across your stomach, but you don't complain
> Then she sets to eating, her tongue pushing into your stomach, trying to get under the piece of pancake
> She maintains eye contact the entire time
> Too cute, like she's asking permission
> Miss Tress puts a hoof on either side of the pancake, her right hoof perilously close to your breakfast sausage
> About halfway through, she lifts her head
> "You like this, don't you? You d-dirty human."
"It's kinda nice, Miss Tress. I'm thinking we could do this every morning, and I could shower afterwards. Then I can be your dirty human, and we won't have to worry about dishes. What do you think?"
> She turns her head, hiding behind her mane
> "I-it's good that you know your place. I-if you have nothing better to do."
> She fidgets, and her hoof brushes against your cock
> You decide not to mention anything, even as you get a full erection
> You don't want to make it weird
"Speaking of which, the pancake is getting lukewarm. You might want to finish that, Miss Tress."
> She smiles at you
> "You are such a good boy."
> Then the licking and probing resumes, her gentle tongue lapping up the pieces slowly, savoring each bite
> She almost looks disappointed when the last bite disappears
"Well, off to the shower for me. See you in a bit."
> Fluttershy latches onto your leg
> "Don't go! I-I mean, we sh-should shower together. Your Mistress commands it."
> Your Miss Tress?
> You didn't realize how close you two had gotten 
> You ruffle her mane
"Anything for my Miss Tress."
> She blushes and looks away
> You chuckle and head off to the shower
> As you walk, poor Miss Tress can't seem to match your pace
> Every few steps she speeds up and her snout bumps against your butt cheek
> Cute
> In the bathroom, you bend over to turn the hot water knob
> You hear a splash, and idly wonder what Fluttershy is doing at the sink
> Once the water is suited to your preferences, you step under the spray with a sigh
> Fluttershy joins you in a moment, some sort of scrubbing pad around her hoof
> "Will you let me wash you? I mean, let me wash you, m-my pet."
> How nice of her
"Thank you, Miss Tress."
> She shyly presses the pad against your stomach, making slow circles and leaving behind suds
> You lose yourself in the sensation, letting her ministrations soothe you
> Then she starts rubbing the pad against your erection
> Your eyes snap open 
"Miss Tress?"
> She's really getting into it, that coarse, slippery material doing a number on your curtain rod
> Fluttershy fixes you with an intense stare
> "This is for your own good, m-my p-pet."
> You guess she is serious about personal cleanliness
> You try to be quiet, but it's been a while since anyone else touched you down there, let alone in a shower
> You feel something start to build
"M-miss Tre-"
> "Hush, don't you worry your little head."
> That's exactly what you are worried about
> You groan as it all becomes too much
> Your cock fires off a salvo or two, and only then does she slow her scrubbing
> You look down to see some white spattered across her mane
"I'm so sorry, Miss Tress! I didn't mean to-"
> She shakes her head
> "Don't worry, my pet. You can clean me after I'm done with you."
> That does make you feel better
> Fluttershy swipes as high as she can, but it barely reaches the middle of your chest
> She frowns, then gets up on her hind legs
> Even then, she only scrubs so high
> In the end, Miss Tress has to be almost pressed up against you to reach your shoulders
> This sandwiches your cock between the two of you, and it gets harder as she shifts her weight slightly
> How can a pony be so oblivious?
> Well, you're not complaining
> After a few more moments of that, all that's left is your head
> The pony pours some shampoo on her scrubbing pad, and lifts up her forehooves
> "Pick me up, um, if you have time."
> Too cute
> You lean down and get a grip under her thighs
> As you lift her up and she straddles your stomach, a problem occurs to you
> You have a mad boner, and right now it's prodding the cleft of her buttocks
> Crap
> Well, she's been oblivious so far
> Then she starts wiggling around, lathering your hair with shampoo
> Her rear slides down a little, her flanks stroking your cock with her every little movement
> Then she stops, and you groan
> Miss Tress taps you on the shoulder
> "You can let me down, if you want. It's time for you to rinse."
> You sigh
"Yes, Miss Tress."
> She giggles as you set her down on the tiles
> As you lower your head into the spray, you try to ignore the almost painful erection you have
> That done, you turn to her
"Your turn."
> Fluttershy gives you the pad, and you set to scrubbing her down
> There are a few times it gets awkward
> When you scrub her chest, even though you know nothing is there
> When you get to her teats, she has to prod you to continue
> You try to ignore the sounds she made then, but your boner heard them perfectly
> When you got to her flanks, she almost growled to get you to scrub then firmly
> Finally she spreads her legs
> "Don't get soap in there, um, that would be very bad. Just stir it around in there, that should be enough."
> She can't be serious
"So I just stick my fingers...in there?"
> Miss Tress looks at you over her shoulder
> "You sh-should use something th-thicker. L-like a rod, or a sausage, or a, a thing. D-dangling thing. Um. If you want. That is, your mistress commands you. Please?"
> How can you say no?
"I understand, Miss Tress."
> You spread her cheeks a little and guide your rod in between, butting up against the pearly gates
> You slowly press forward, her delicious warm welcoming your aching member, inch by inch
> She whimpers and pushes herself further on your dick
> As you hilt, you shift your grip to her hips, that soft flesh giving way beneath the pressure of your fingers
> "I'm y-your pancake~."
> What
"What."
> She starts to buck her hips, and any further words are torn from your mind
> "Fill me with your sweet,"
> You thrust in rhythm with her
> "Sweet,"
> Both of you are panting now, your water slicked bodies moving together, heated beyond the steam that fills the bathroom
> "Syrup."
> As you gaze down at her roiling body, her wings erect and glistening, her long, wet, elegant mane plastered to her head, you start to suspect she likes you more than as friends
> As her whimpers turn to groans, still quiet and small, but filled with need, you think you like her too
> You lean down along her back, and whisper in her ear
"I love you, Miss Tress."
> All at once, you are buffeted by her stiffened wings
> Fluttershy's pussy clamps down around you, its muscles spasming in waves
> You groan as your cock unloads rope after rope of cum deep inside her
> You end up spooning on the floor, letting the shower spray unheeded across your recovering forms
> You hug her against your chest, exulting in her softness and warmth
> As the two of you relax in spent euphoria, you idly wonder what her fetish could be
> Might be fun to make it a guessing game
