Rarity nerved herself to broach the subject. "Fluttershy...there's something I wanted to ask you about."
The pegasus focused on her friend, hearing the uncertainty in her voice. "Of course! You know you can ask me anything."
Rarity felt her heart thump as she lifted her teacup, sipping from it and glancing around her living room to gain a moment to gather her thoughts. "Well, last week, I was heading to the shops and I saw you. I was going to call to you, but I realized you were heading into the woods with that chestnut fellow, and you looked like you had something naughty in mind."
"Muddy Meadows." Fluttershy smiled. "I could introduce you. You know I'm not jealous."
"Oh! That wasn't...quite what I meant." A flush was creeping into Rarity's cheeks. "He is certainly very pleasant to look at. Perhaps...anyway." She refocused. "The next day I was visiting Daisy, and Roseluck dropped by with her temper up. She had been out behind her garden, and apparently found quite a quantity of...." She struggled to get the word out. "Manure."
Fluttershy blinked innocently. "Oh? What was the problem?"
"Well, she wanted to remind her neighbors, very passive aggressively I might add, that she had installed a composting toilet next to the garden, and everyone was welcome to use it. And that going in the woods not fifty yards away amounted to malicious...actually, I don't think I'll use her exact words."
Fluttershy quietly laughed, both at the image of the furious gardener and her friend's difficulty with the indelicate topic. She had an idea where this was going, but Rarity was cute when she was flustered and she wasn't going to make it too easy for her.
"At any rate, I didn't say anything, but I did see you headed in that direction, and...." She trailed off.
"And you wondered if we saw the mad pooper?" Fluttershy tried to blink innocently again, but she couldn't hide the grin spreading across her face.
"Fluttershy! I'm trying to ask...."
That was enough teasing, she decided. "If we did it? We did. Well, I did. I saved up a whole week's worth of poop, and I pushed it all out while he watched. And I let him cum in my mouth while I was pooping."
"oh." Rarity's voice was suddenly very small and quiet. "...goodness gracious." The flush had practically turned her whole face scarlet by this point. She visibly collected herself. "I thought it might be something like that. And, well, I wondered if you might like to do something like that with me."
Fluttershy was surprised. Like most best friends in Ponyville, she and Rarity would get off together from time to time. They would share stories about stallions, and on a couple of memorable occasions, shared the stallion himself. But she would never have guessed that Rarity would be interested in this sort of thing. "Oh Rarity, I'd love to. Why don't we make a date? I need to save up, and usually I'm careful what I eat–"
"Actually, darling," Rarity let her mane fall over her eyes, having difficulty meeting Fluttershy's eager gaze, "I'd like to be the one who...exhibits herself."
She steeled herself. She'd rehearsed this part, because there was no way she could articulate something so difficult in the moment. "Sometimes I feel...constrained by who I choose to be. Like I can't allow myself to feel certain urges, because they aren't appropriate. And I have had...this image burning in my mind. I can't seem to escape it, and I think I have to know what it feels like for real. And I could only do it with someone I love and trust completely, and, well, that's you." She dropped her gaze again.
Fluttershy leaned forward to put her hoof on Rarity's. "Rarity, I would be honored to watch a big poop come out of you."
Rarity laughed, the tension broken by the sincere but utterly ridiculous sentiment. "Thank you, darling."
"What time of day do you usually go? In the morning?" At her nod, Fluttershy smiled. "Why don't I spend the night? I'll just go home and feed everyone real quick. See you soon?"
"Yes, that sounds delightful." Rarity was startled when Fluttershy went in for a kiss, even moreso when her tongue slipped into Rarity's mouth. Clearly she was every bit as excited at this thought. They drew apart and Fluttershy left, casting one last flirtatious look over her shoulder.
Fluttershy was practically delirious with desire as she fed and watered the various animals. The times she and Rarity had slept together, Rarity had been a sweet and attentive lover, but she had been just as elegant and dignified in bed as she was in the street. Now she'd had a glimpse of the lust Rarity kept under control even when she was muzzle-deep in a lover's pussy. She double checked her chores, making sure no one went hungry just because she was in a hurry to get laid. Then she grabbed her overnight bag and headed back.
Rarity stepped out of the bathroom, pressing the last of the shower water from her mane with her magic. Fluttershy was already sitting on the bed, her wings spread to dry in the air and her mane wrapped in a towel atop her head. Rarity couldn't help noticing that her tail was flagging. Since they usually only wore clothing on special occasions, it was unremarkable to catch a glimpse of her friends' genitals, but Fluttershy was now lewdly displaying her pussy and asshole. She noticed where Rarity's gaze had settled and winked her vulva, exposing her pretty pink walls and her throbbing clit. She patted the space next to her. "C'mere, you."
Rarity lowered the lights and settled beside her. She kissed Fluttershy hungrily, and moaned into her mouth as Shy's hoof found her teats, the soft frog of the hoof delicately stroking her sensitive flesh. Rarity's horn glowed as she began using her magic to caress her lover without opening her eyes or slackening her kisses one bit. She tweaked and teased, never lingering in one spot, until Fluttershy couldn't bear it anymore and broke the kiss. She grabbed Rarity's forehoof and pressed it into her crotch.
Rarity flexed her fetlock, pressing the joint against Fluttershy. Then she withdrew, a strand of fragrant goo lengthening between her hoof and Fluttershy's cunt. She raised it to her mouth and darted her tongue out to taste the juices matting her coat. Then her horn flared and an azure glow enveloped Fluttershy's pussy, stroking and massaging. While Fluttershy rode a wave of pleasure from her gentle but unceasing arcane stimulation, Rarity's mouth wandered over her friend's other erogenous zones. She lapped at her twitching ears, gently tugged at her primary feathers with her teeth, returned to her face to practically drive her tongue down Shy's throat, then nuzzled her soft teats, sucking and biting the hard nipples. The delicate aroma of Fluttershy's cunt was irresistible, and finally she buried her muzzle in the delicious gooey mess and started really trying to make her friend cum.
Some time later, Fluttershy lay gasping and quivering, proof of Rarity's thorough success. Rarity leaned in for another kiss, and Fluttershy eagerly licked her own fluids from the unicorn's face, tonguing them right back into Rarity's willing mouth. She came up for air and gazed directly into Rarity's eyes. "My turn now. Lay back and let me work."
Rarity grinned. "Yes ma'am." She began to roll from her side to her back, but Fluttershy stopped her with a hoof on her rump. She acquiesced and flicked her tail, giving Fluttershy complete access to her treasure. She nibbled at Rarity's labia, enjoying the flavor, the heat, and the quiet moans she elicited. After a moment her reason for keeping her friend on her side became evident. Her hoof took over the task of stimulating Rarity's pussy, its soft, velvety underside tenderly pressing against the even softer vulva. Meanwhile, she began to lap at Rarity's anus, bathing the squishy ring of muscle with wet heat.
"OoooOOoohh!" Rarity cried. "Oh! Oh darling, that feels so good! Ohhh, don't stop!"
Fluttershy had no intention of stopping. She'd always believed Rarity's prim reserve concealed secret desires, but she'd never had the courage to try to find out what they were. Now that Rarity had revealed a kink, she was going to find out just how much of a butt slut her friend really was. The results so far were encouraging.
Rarity humped backwards against her hoof and her tongue, desperate for more. Then she abruptly sat up. Her magic gripped Fluttershy firmly, flipping her onto her back. Looking half-crazed, she straddled her friend and sat down firmly. Fluttershy squeaked at the sudden displacement, but soon closed her eyes to concentrate on her task.
Fluttershy's lips encircled her friends anus. As she swirled her tongue across the puckered center, she sucked, her cheeks hollowing. The plump asshole pressed against her tongue. Rarity had of course cleaned herself thoroughly in the shower, but the tang of clean skin was beginning to mingle with a muskier flavor from deeper inside her ass. Rarity's ponut was lewdly flexing, puckering as if to kiss her back. She speared her tongue into the center, and suddenly it was through the ring and enveloped by Rarity's rectum.
Now her tongue was the passive element in her oral embrace, being squeezed by Rarity's hot asshole. She concentrated on staying in as deep as she could despite Rarity's writhing and bucking, and enjoyed the flavors and the sounds that washed over her. Rarity was panting and gasping, close to orgasm from anal stimulation alone. Marecum drizzled onto Fluttershy's face from the beautiful pink pussy winking against her nose. She broke the suction on Rarity's asshole with a pop, and slithered her tongue out of the delicious depths to a protesting whine from Rarity. She took a deep breath and pressed against the hot cunt, pushing barely inside as she stretched Rarity to her limit, then withdrawing with delicious maregoo coating her nose and mouth. Rarity's rectum was still gaping and yearning for her tongue's return, and she drove it in deep. At that fresh assault Rarity came, wailing out her orgasm and grinding into her friend's slimy face.
She lifted off Fluttershy's face and the butter-colored pegasus gasped, regaining the oxygen that Rarity had cut off in her frantic climax. Rarity settled beside her, lapping at the vaginal fluids that festooned her friend's face, and deeply kissing her to savor the taste of her own asshole. They snuggled up tight and fell asleep nose to nose, sharing each other's breath in spent bliss.
Rarity woke to the scent of coffee. Two cups were sitting on her nightstand and Fluttershy was already back in bed with her. She sat up, and they shared coffee and kisses until she started to feel her bowels waking up as well. Fluttershy heard a gurgle from her flank and giggled. "I knew coffee would do the trick. Shall we move this to the bathroom?"
"Actually, I have a better idea," Rarity said. Fluttershy watched with interest as she prepared a spot by unrolling a futon on the hardwood floor. "This is for you, darling...and so is this." She levitated a firm cylindrical pillow that Fluttershy recognized well. It was good for lounging, but its true purpose was to grind against, a way for a mare to get herself off when mouths and magic were already busy elsewhere.
As she made herself comfortable on the futon, Rarity stepped out and retrieved something from a hall closet. She returned with a big heavy object, and Fluttershy cocked an eyebrow. "Is that...a chamber pot? Did you get that just for the occasion?"
Rarity laughed. "Oh no, this has been in there for years. When we were much younger, Sweetie Belle would get too scared to leave the bedroom in the middle of the night, even for the toilet. After one accident too many, Mother got this from an antique store and made her keep it in her room. But I think it will be perfect for this, don't you?" She placed the pot on the floor and started to get into position.
"Um, Rarity? Could you bring it a bit closer please?"
"Oh! Certainly darling. I didn't know if you'd–"
"It's fine. I want a really good look." She smiled. "And a good smell too."
Rarity positioned herself and squatted, just inches from her friend's face. Fluttershy could smell Rarity's holes, her own dried saliva from last night's fun, and the slightest undercurrent of body wash. Rarity was trembling now, whether from anticipation or holding back her load Fluttershy couldn't say. She leaned forward and planted a gentle smooch right in the center of her friend's soft anus. "OK, little miss Ponut. Let's see what you can do."
Rarity whimpered at this, and moments later a fart blasted from her. Fluttershy giggled as the puff of gas tickled her face, then inhaled noisily. She admired the hole flowering open in front of her, first pink and then revealing a dark, rich brown at the center.
Rarity was feeling the pressure build inside. Her body had decided it was time, and all she had to do was let it happen. There was a pit of anxiety in her stomach, crying out for her to stop, that a lady couldn't do something so vulgar as defecating with an audience. But further down she sensed a steamy warmth, whispering to her, urging her to release, to show her friend and lover the most intimate, most secret act she could perform. She looked over her shoulder, emotions battling on her face, and saw only awe and lust in Fluttershy's gaze. With a soft grunt, she began to push gently.
Fluttershy was absolutely entranced. She knew how good it felt to release her waste with an audience, but she had never dreamed how lovely being that audience could feel. If Muddy Meadows had been interested in reversing their roles, she would have been happy to watch him, but more for his benefit than hers. She didn't find the thought of a shitting stallion arousing by itself. But Rarity, elegant, proper, fastidious Rarity, grunting and struggling to push a thick turd through her beautiful shithole, was the most erotic thing she had ever seen. It emerged inch by inch, its dark and knobbled texture contrasting obscenely with the soft alabaster rump working to expel it. Fluttershy realized she was taking shallow breaths through her mouth, panting with lust, and she forced herself to close her mouth and inhale deeply. The odor filled her sinuses, musky and acrid, but with an undertone of sweet hay. The flesh of Rarity's delicate hole stretched and undulated, matching the contours of the turd beneath as it pushed through. Fluttershy realized that at some point she had gripped the cushion between her thighs, her hips pumping, urgently pressing her hot vulva against the velvet slipcover.
The log began to droop under its own weight as it slid out of Rarity. Her cunt flexed as she pushed, and scattered droplets of pee fell from it like polished topaz. "Oh Rarity! Pee for me! Let it go!" Fluttershy said urgently. The tiny mouth of her urethra suddenly opened wide, and a moan of relief accompanied the stream of dark morning urine. Fluttershy watched as it splashed against the sagging log, which finally separated to fall into the pot with a thick plop. Staring at the stump of the turd still protruding from Rarity, her ears full of the ringing of urine on porcelain and her nose full of the aroma of a firm, healthy shit, Fluttershy came, smearing her hot fluids across the pillow.
Rarity watched her friend's face as the orgasm took her, as she shivered and squeaked but never closed her eyes, never took her gaze off the filthy act being performed just for her. Rarity couldn't bear the lust building inside her another moment. As her pee waned to a dribble, her horn flared, and an azure cloud of magic began to work in her cunt, spreading apart the rubbery lips and massaging the pink knob of her clitoris. Another thump sounded as a second piece separated from the wide log still slowly sliding out of her. The thought that she was showing Fluttershy the filthiest and most private secret of her body, and her friend positively reveled in the sight, burned in her mind as she hurtled over the precipice into a crashing orgasm.
Her knees went weak. The ferocious spasms washing through her vagina and rectum pushed the final length of the massive turd out of her, falling atop its siblings in the cooling piss at the bottom of the pot. A small wave of whitish marecum slid out of her winking vulva and draped itself across the mound of shit like icing on a pastry. For a moment her rectum gaped open, then her anus rolled inward, withdrawing the pink folds of tissue so thoroughly that no mess remained on the outside. No fecal mess, at any rate–her pussy was dewed with her cum and piss, but Fluttershy was already eagerly addressing that with her tongue. After enjoying her attentions a moment more, Rarity lay down on the futon, pressed snugly against her friend's side, and peered curiously into the pot. "Do you think we should take this to Roseluck?"
Fluttershy giggled and kissed her on the cheek. "Thank you for showing me that. Now I know how much fun it is from the other side."
"Yes, about that...."
Fluttershy couldn't help grinning a little deviously. "So you want to try that too, huh. I think I have enough to give you a little show...."
