"Join us!" the group echoed. Before Celestia knew it, she felt hooves all over her body lifting her from the ground and carrying her to the bed where Luna had just been. The mare that had been at the center of attention faded into the background, watching the group shift their gaze to the newcomer. The stallion with the blue fur that had partaken in the glory hole earlier shuffled onto the bed, laying on his back and clearly ready for another round.

Celestia felt herself being settled on top of him. He wasted no time in establishing his role in the new configuration, reaching up and pulling her hips down to his waiting shaft. He slipped into her with little difficulty as he began to hump upwards with following thrusts. A new set of ponies appeared in front of her. A pair of stallions to either side of her as she took their members into her waiting hooves. The mare in front of her backed up to the bed, presenting herself. Her tail was a light pink, and her fur was just barely off-white. Celestia had no room to maneuver as she pressed her marehood into her stout, expecting attention. Celestia could only comply, pleasuring the mare as best as she knew how. Over the wet sounds of sex, and moaning all around her, she heard the door open.

"Sorry I'm late, I just got the most gnarly blowjob from the gloryhole down the hall," the white stallion said. He could see Celestia in the middle of the assembly, getting fucked from below with her ass in the air. "Well I see that I'm not too late." He climbed onto the bed and pointed his dick at the tight hole beneath her tail while the blue dick of the pony under her continued to trounce her vagina.

The white stallion pushed the tip of his already-slick cock against her backdoor, slathering it with lubrication before trying to push inside. Celestia's eye's went wide as she felt the attempt at invading her anus. She tried to cry out, but was instead only muffled into the mare's pussy mounting her face.

"Oh. My. GOSH!" the mare cried out at the vibrating sensation of Celestia's pleas into her pussy sent her reeling over the edge, flooding Celestia's mouth with her mare cum. All around her, Celestia felt the prods of numerous cocks as stallions clopped themselves and rubbed against her fur. She regularly felt fresh spurts from one or another marring her fur yet another streak of white. The stallion at her ass pushed a bit more, finally slipping the tip inside. Celestia cried out.

"AHHhhRGHMMMFFF!!" her cry was cut short as the mare had shifted up onto Celestia's horn and an enterprising stallion took her place in front of Celestia, placing his ready cock into her conveniently open mouth mid-yell. It was the distinguished stallion from the door earlier.

"Ah, do be a dear and, see to taking care of this would you?" he instructed more than he asked.

"Mff Mfff!" she struggled. He could not see the worried expression on her face beneath the mask as the stallion in her ass continued his assault. It was already a tight enough squeeze, only made worse by the stallion in her pussy occupying so much of her pelvic real estate. With the girth of his dick head buried, the hard part was over, for him. He wasted no time in pushing more inside with short thrusts, stretching her insides wider as he sunk more and more into her tender asshole.

"Mff MFF!" Celestia tried to scream, but only serving to stimulate the cock in her mouth.

"Ah yes, that's the spirit. I do so enjoy a mare who can hum while giving a hummer. Say, do you think you could do 'Trottingham Bridge?" he asked. Behind her the other white stallion pushed the last bit of his shaft into her.

"Mmrmph MFF Ngnhh!" She winced as she felt the two stallions piston in and out of her, rubbing against eachother through the thin membrane on her insides separating them.

"Hmm, that's not quite the tune. But kudos on the effort." The mare squatting on her horn caused her to bob her head deeper onto his cock as she felt her juices running down her forehead. The burning pain of her ass slowly gave way to pleasure as the stallion beneath her continued to fuck her pussy, slapping against her swollen clit.

One of the mares who were masturbating nearby brought herself to climax. A bit of a gusher, she was, spraying down Celestia's mane and plastering it to her neck. It must have been somepony's fetish as she was tackled shortly thereafter, getting fucked somewhere out of sight. Celestia felt another orgasm roll through her, sending ripples of contractions through her nethers. It was the last straw for the pony under her. She could feel him thrusting more frantically and begin to swell inside her.

In a burst of adrenaline, she tried desperately to lift herself up off of the stallion and get him out of her, even with the mare on top of her and the stallion in her ass pinning her down. The stallion, likewise did not want a paternity test coming back to him under shady circumstances, tried to wiggle free. By their combined efforts, she managed to pop him free at the last moment as he loosed the first couple of ropes against the underside of her belly. Surrounded on all sides by ponies, he was trapped until the end of the ordeal as the rest of his cum soaked into his own fur. With more room now, the stallion in her ass began to fuck her with gusto. With no other shaft to block him, his balls smacked freely against her wanton clit, peaking out with each wet slap.

"Mmph, Mmff, MMMmmmm!" Celestia moaned onto the cock as she came yet again. Each crest, each peak of pleasure melding together into a plateau of ecstasy.

"Oi, blimey!" he remarked. She felt each of the stallions at either end of her nearing theirs. The cock in her mouth pulled back one last time to give her a chance to take a deep breath before he pushed his belly into her nose, cumming into her throat. At the same time she felt the other flaring deep inside her ass, dumping his load far into her other end. One withdrew first, letting her gasp for air and the other pulled out of her ass with a wet 'plop'. She practically deflated onto the bed from exhaustion. The stallion under her squirming out of her way at the last moment, the mare on her horn toppling forward onto the floor.

"I think we broke her," she heard another mare say. Celestia looked up with blurry vision through the eye holes in the mask. Luna was standing in front of her. Another mare was straddling her back, though without a saddle. Luna looked to be dripping with sweat. When the acrid scent of ammonia hit her nostrils, Celestia realized that the source was coming from Luna's 'passenger'.

"Ass to ass!" a nearby stallion said, holding up a double-ended dong, motioning to Luna and the broken mare on the bed. Celestia could barely lift her head off the sticky sheets.

"Hmm, not tonight boys. Perhaps next time," Luna said. She looked to the mare on her back. "I'm afraid I'll have to cut your ride short," she said. The disappointed mare slid off of her back. Celestia felt herself being lifted into the air and slung across Luna's warm, wet back, courtesy of her previous rider. Celestia hadn't the strength to complain. "Alright, let's get you home."

A flash of light later and they were back in the castle, in the royal washroom. Luna slumped her sister into the shower stall, propping her against the wall, discarding their masks onto the counter. She got the water running and rinsed herself of the various fluids and also the black paint from her flanks. She took the shower head and detached it from the wall mount, extending the hose to the other mare, likewise rinsing her down.

As much fun as Luna had being bathed in stallions' baby batter, and by golly it was a lot of fun, getting it out of her sister's fur, main, and tail as well as her own, was a nightmare in itself. But with time, patience, and scrubbing, she got them each clean. Celestia managed to keep herself on her hooves long enough to be toweled dry, and helped into bed.

"Was it everything you hoped for?" Luna whispered.

"Mmm." Celestia responded in a neutral hum, neither to the affirmative or otherwise. She fumbled for the clock on the nightstand. She was due to raise the sun in just a couple hours. She rolled over and groaned.

"Don't worry about that. I can raise the sun this one time," Luna promised.

Although it was an hour late.

And that was how daylight savings time started.
