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...."
