Lyra wipes her.

At a fancy party, Lyra and Dash head to the mare's room and have a pee. Lyra really likes what she sees under Dash's tail.

Contains: pee. Obviously.

A trip to the mare's room

Lyra took another sip of her cider, levitating the mug to her mouth. It was really quite good; usually Canterlot wasn't a place for a cider fan to find satisfaction, being more of a hard liquor town, but this was the Palace, after all. Twilight had probably gotten the Apples a contract to supply cider by the case.

The garden sat five stories up, on a terrace, overlooking Canterlot and the countryside beyond, the sun lowering towards dusk and providing a soft golden light across everything. Ponyville was visible as a smudge in the distance. The sounds of the party swirled around her. Uniformed waiters circulated with trays of canapés.

Pinkie sat sullenly in a corner, glowering, because she wasn't allowed to be in charge of the party.

Lyra took another sip of cider and then noticed: quite a bit of pressure was building in her lower abdomen. Her tail was trying to raise itself and her bum squirmed on the soft silk upholstery of the chair. Another few seconds and there was a chance the fine silk chair cover would need a laundering.

But she didn't want to go to the mare's room alone. It was just one of those things; she didn't like going by herself at a party or dinner.

Wow, too much cider. Lyra's face twisted as she clenched, her tail whapping on the chair, the sound of the conversation around her going all dim and tinny as she fought against the sudden desperation.

"I've gotta pee," Rainbow Dash announced and flapped away from her chair between Twilight and Rarity, heading toward the doorway to the inside of the palace.

Oh, thank Luna. "I'll come with!" Lyra announced, slipping from the chair and shuffling forward, her tail tucked low in case the movement of walking made her pee before she got to the potty.

"Hey, Lyra," Dash said, looking down from her low altitude. "Howya been?"

Lyra looked up. Dash's tail was angled very slightly up, but her flight altitude gave Lyra the exact angle to stare at Dash's naughty bits, just in front of her nose, as they trotted. Dash flew with her own rear legs crossed tightly and the labia throbbed with every single beat of Dash's wings, her clitoris engorged, far extended from its hood.

Heh, Lyra thought as she shuffled painfully down the stone castle corridor, past two armored guards, towards the mare's room, Dash has to pee just as badly as I do. Too much cider, friend?

They turned the corner and saw a long line outside the mare's room. Fluttershy, last in the line, sat on the floor, forelegs wrapped around her hips, rocking desperately.

Dash flared wings and arrested her momentum, now hovering, and Lyra ran headfirst into her, her horn poking Dash between her labia and left butt cheek.

"Ow! Hey, watch it Lyra. Also, I don't think I'll make it, waiting for that line."

An armored guard happened to be trotting past as Dash said that. "Hey, Dash. Long time no see."

Lyra looked at her: the guard was a pegasus mare about Lyra's color, with a teal tail and helmet crest.

"Hey, Angel. How've you been? Haven't seen you since high school. Is there another mare's room? I'm about to have a cloudburst."

"Sure, follow me." The guard led them a few steps down the corridor—Lyra felt a single drop wet herself as she shuffled to keep pace—and pushed through what appeared to be a solid section of stone wall. An exquisitely hidden stone door swung on silent hinges, revealing a narrow but well-lit corridor. "First left."

"Thanks!" Lyra and Dash said simultaneously. The corridor was narrower than Dash's wingspan, so she dropped to her hooves and they entered the narrow doorway, shoulders rubbing against Lyra's.

"Catch up with me later, Dash," the guard called. The door slammed behind them.

"I'm gonna wet myself," Dash muttered. "Too much cider."

"Same," Lyra said with a frown. They turned the corner at the first left and both paused, eyes widening. Lyra was no architect, but the massive locker room was somehow hidden inside the dense stonework and towers of the Palace, despite being entirely behind the scenes and invisible to the average visitor. That was an impressive trick.

Everything was faced in polished gray stone, the ceiling vaulted and held by marble columns, stained glass likenesses of Celestia and Luna shining in the evening sunlight. Lamps lit the space brightly and benches faced banks of lockers.

A long marble trough butted up against the east wall, under a wall-length mirror, and the inviting sound of flowing water emanated from it.

"Oh heck," Dash said. "That sound is gonna get me."

Lyra bit her own tongue and nodded.

Both mares waddled to the trough, turned around, and poked their butts over the edge. Dash reached back and grabbed her tail, holding it against her right cutie mark with her right forehoof, and Lyra just flipped her tail to the left.

They both turned to look over their shoulders, at the mirror, and Lyra stared at the reflection of Dash's rear, and she saw Dash's eyes were locked on Lyra's privates in turn.

"Uggh, so hard to start when you have to go this bad," Dash said. Her blue labia spread wide, exposing the bright pink of her treasures, a stupendously huge clit throbbing with her heartbeat.

A wave of self-consciousness swept over Lyra: her own pussy was far more modest, the labia thinner and much less meaty, the clit tiny. Dash's backside seemed somehow appropriate for such a well-known athlete, heavy and powerful. "You look good," Lyra said.

Dash stared into the mirror, checking Lyra out. "You too—"

Lyra started her stream, a thin trickle that arced out and into the water flowing down the trough.

"Oh, thank goodness," Dash said as her own stream started, much faster and stronger than Lyra's own.

Lyra sniffed lightly, the scent of Dash's pee strong with the cider and booze. "You enjoying the party?" Lyra asked.

They both tore their eyes away from the mirror and the other mare's backside and looked at each other's eyes. "Yeah! These Palace events are usually too stuffy for me, but this one isn't bad."

"How's Twilight been?" Lyra asked. "I haven't seen her lately."

Dash grunted, her powerful stream dropping to a trickle and then ending with a last squirt. "She's good. She's been seeing somepony but won't tell us who."

"Really?" Lyra's own stream continued, splashing into the flowing water. "Any guesses who?"

"She smells like cum sometimes, so it must be a stallion, but that's all I've got. She can teleport so we can't spy on her."

Lyra's ears perked straight up and her eyes crossed as she squeezed down, getting a few last drops out. Dash's eyes widened, staring at the mirror.

"You must exercise that thing a lot," Dash said. "Your whole pussy clenched really hard."

"A bit," Lyra said. A glance at the mirror told her she and Dash were both wet with golden droplets. Her horn lit and magic reached out, gathering a dozen hooves of paper from a toilet roll a few steps right of Dash. "Here, turn toward me."

Dash raised an eyebrow and then turned around, pointing her rump at Lyra. Lyra wadded up the length of paper and grabbed the wad between her front teeth.

The rainbow tail was still held tight to Dash's right thigh. Lyra dipped her head down, looking up at Dash's heavy labia. The few drops of pee remaining shined brightly in the evening sun that filtered through the stained glass. Delicately, Lyra extended her neck until the wadded paper made contact with the fluffy blue fuzz just in front of Dash's clit. The smell of Dash's pussy filled her nose, with a sharp hint of pee, too, but mostly alluring pussy smell. Lyra wiped upward, slowly, pressing with the wadded paper and running it across Dash's clit, up between her lips, and then over the tight pucker of Dash's bumhole. She spit the wad of paper into the flowing water, and it was carried away toward the drain at the far end of the trough.

Lyra then turned back to Dash's backside and extended her tongue, brushing it across the huge, thick clit. Dash squeaked and a jolt ran up her body, the forehoof she balanced on tapping on the stone floor. Lyra's tongue brushed up and down between the meaty pussy lips, sampling the tastes and letting Dash's scents fill her nose. She then raised her snout and nipped at the dock of Dash's tail.

"All clean," Lyra said with a grin.

Dash looked over her shoulder and released her tail, bopping Lyra in the nose with it. She blinked a few times, the cider clearly affecting her as she struggled to find words. "T-thanks, Lyra. Turn around."

Lyra smiled and turned her own rump toward Dash.

Closing her eyes, Lyra heard the sound of Dash pulling a length of paper from the toilet roll. She raised her tail, flipping it up over her spine, and raised her head in anticipation.

Hot breath played across her own dampness, tickling the soft fuzz that surrounded her nethers and blowing against the drops of hot urine that she still felt beading her. The wad of paper pressed against her own clit, rather more firmly than she would have wiped herself, and dragged upward, rubbing her labia uncomfortably. Then, there was a pleasant pressure as Dash pressed it against the tight muscular ring of Lyra's anus. A tiny "Oh!" escaped her and Dash paused, hesitated, and then pressed forward again, the wad of paper firmly against her butthole.

There was a plop sound as Dash dropped the wad of paper into the flowing trough.

For a moment, nothing. Lyra wondered if Dash was drunk enough she was going to forget to reciprocate—

A hot tongue pressed against her clit and fireworks lit off underneath Lyra's closed eyelids, the sensation like a lightning bolt from her rump, up along the underside of her torso and into her head. Dash nibbled Lyra's tiny clit, just brushing it with the surfaces of her teeth, before her tongue drove deep into Lyra's channel. Muscles clamped on Dash's tongue, fighting to hold it in as Dash thrusted with it. Lyra's flows began, very slightly, as her excitement burgeoned, and then Dash stopped, pulling back, away from Lyra's bum.

"Hey, Lyra?"

She panted, eyes clenched tight. "What?"

"You liked it when I wiped your butthole," Dash said.

"Y-yeah." Lyra turned her head and opened her eyes and saw Dash wore an evil grin on her face.

"I liked it when you wiped my butthole."

"Oh?"

"Let's find a stallion at the party and have him fuck both our butts."

Lyra nodded. "Bonbon's dick is bigger than any of the stallions'."

Dash said, "Plan."
