Cum and Play

When the light faded, Celestia and Luna found themselves in a large, mostly empty room. It was a plain cube, with walls that were flat and mostly featureless, though each one was painted in a different garish color. The floor and ceiling were painted as well, bright neon shades that rather hurt the eyes. There were no windows, and there were also no doors. The room's only features were two large computer screens set into one wall and a kind of pedestal or podium in the center of the room which had a large red button on top of it. Celestia walked over to the button and rolled her eyes. It was marked with a quite clear picture of a penis.

"Not much of a puzzle if there's only one thing you can do," said Luna, looking at the button with disdain.

"Knowing Discord's idea of a joke, I'd rather not push that," said Celestia. "Let's make certain there are no other options first."

Luna nodded and the two mares searched the room thoroughly. Every inch of all four walls were inspected. The screens were examined thoroughly for buttons or switches or any other way to activate them. The floor was tapped and poked, even the ceiling was explored in detail, but there were no hidden switches, no secret doors. Just brightly painted concrete with one obvious option.

Finally, with a long-suffering sigh, Celestia put a hoof on the cock button and pushed it.

A whooping klaxon sounded and two previously invisible holes in the floor opened up. A pair of pedestals rose slowly, and each one was topped with a large rubber dildo, realistically shaped like a stallion's cock, complete with balls. They rose, wobbling gently, until they were at about hip height, positioned such that the alicorn mares could climb onto them if they so desired.

Celestia rolled her eyes again, while Luna glared at the lewd objects with obvious disgust. In front of them, the screens suddenly came to life, each one displaying a line drawing of a similar cock, with horizontal lines across them at regular intervals, as if they were rulers.

"And just what are we supposed to do now?" said Luna, still scowling.

"I'm afraid it's all too obvious." Celestia reached out with one hoof and poked the dildo in front of her. A thin line of red appeared at the bottom of the matching drawing on the screen. She stroked a hoof down the cock and more red appeared, filling up the dick-diagram from the bottom.

"Ah," said Luna. With a sigh she reached out and stroked the cock before her as well, and her diagram began to fill.

Celestia shook her head at the absurdity of this all, and then sighed as she noticed the red lines on her diagram sink back down and vanish. Apparently she would have to keep it up. She sat down in front of the dildo and put both hooves on it, and started to stroke it regularly. Slowly the red crept up the diagram. Luna emulated her sister, pumping the false cock up and down. The red line rose at a glacial pace, and if she paused for even an instant it would sink back down. Sometimes it sank back down for no reason at all. It was immensely frustrating. Both alicorns just wanted to get this ordeal over with.

With a scowl of annoyance, Celestia stroked the dildo faster. The red line rose a little more, but it still was taking a small eternity. An idea suddenly came to her. If this was meant to imitate a real cock becoming aroused, perhaps she could speed things up a little bit. Though it would be a further humiliation. Still, she didn't want to be here all day. She leaned in and licked the dildo.

As she'd expected, the red line jumped higher. Celestia sighed. Bad enough she had to touch the stupid thing, now she had to fellate it. Wonderful.

Luna looked over at Celestia, who was now wrapping her lips around the rubber head of her toy. The dark alicorn scowled and stubbornly just kept stroking. Celestia shoved the cock down her throat and tried to give a decent blowjob, even though it was the last thing she wanted to do. The red on the screen in front of her rose higher and higher. Finally it reached the top and a klaxon sounded, the whole screen flashing red. Celestia pulled back from the fake cock with a sigh of relief. It was over.

Then the cock suddenly spurted out a gush of sticky white goo. It splattered over Celestia's face, coating her mane and dribbling from her long, elegant horn.

"Gah!" she said, jerking back, but it was too late. She was covered in fake cum.

"Buck this," said Luna suddenly, letting go of the dildo in front of her. "I have no desire to participate in this base and crude nonsense!" She looked up at the ceiling, as if Discord might appear there any moment to argue with her. Instead the screen in front of her suddenly switched from displaying the penis diagram to showing Discord's face.

"Why Luna, how disappointing. You don't like my puzzle? Well, this is only the first room, maybe you'll enjoy some of the other puzzles more."

"I doubt it," said Luna flatly.

"Alas, your enjoyment doesn't really matter, my dear Moony. Only mine does. This is my little depravity dungeon. And if you care about your friends, you will participate." Discord's grin was positively evil. Then it blinked out and the screen returned to displaying the outline of an equine cock.

"Horseapples," muttered Luna.

"Just do it," said Celestia. "Get it over with and we can move on."

"To some equally disgusting task, no doubt. But yes, very well." She lowered her head and took the dildo into her mouth, her hooves wrapping around its base. She attacked it with something that might have been either fury or enthusiasm, taking it deeply with rapid strokes of her lips and tongue against it. The red reappeared on the screen before her and began rising rapidly, but she paid that no heed, she was focused completely on her task.

It took hardly any time before the red reached the top and the klaxon sounded. Luna instantly let go and threw herself backwards, hoping to avoid being covered in goo. She fell over on her back, but she failed to avoid her fate, the dildo's pulsing jet showered over her entire body. It coated her belly and turned her tail into a matted, wet mess, as well as showering her legs and hooves. Some even reached far enough to splatter across her face.

"Ugh," she said, shaking her head and making an expression of disgust. She climbed to her hooves with some difficulty, since they were coated in goo as well. Fortunately the floor was concrete, so she only slid a little bit.

"Congratulations!" said Discord's voice. "You've solved your first puzzle!" The space between the two screens was suddenly a door that swung open.

"Joy," said Luna sarcastically.

"That hardly qualifies as a puzzle," said Celestia crossly, but Discord didn't reply. Both screens had gone blank. The dildos were still there, but they hung limply, spent. With nothing more to do here, there was nowhere to go but forward. So both mares headed for the door, and whatever demented puzzle might lie behind it.

"Well this is... puzzling," said Luna. They'd stepped forward into what seemed to be a short hallway, but no sooner were both mares in the little space than the doors behind and forward had closed, leaving them trapped in a room barely big enough to hold them.

The ceiling was still brightly painted concrete, but the walls and floor were tiled in gleaming white tile, almost like a shower. The room didn't seem to have any other features, though both mares turned around awkwardly in the small space trying to spot any way to figure out what they were supposed to do.

Eventually Luna spotted a tile on the floor that had her cutie mark etched on it. A second tile proved to have Celestia's cutie mark, and both tiles also had a little symbol, a circle containing three droplets, next to the cutie mark.

Luna tapped her hoof against the tile, but nothing happened. She frowned at it. "What are we to do with these?"

"The symbol seems to signify water," said Celestia. I assume we have to get them wet."

"Ah." Luna's horn lit up, and she conjured a little sphere of water. It hovered before her for a moment before she released it to drop to the tile between her front hooves. It splashed against it, but nothing happened.

"I suppose that would have been too easy," muttered Luna.

"Indeed," said Celestia. "I suppose since our cutie marks are on the tiles, a more... personal fluid will be required."

"Ugh. You don't mean we'll have to pee on them?" said Luna, taking a step back. Her rump ran into the wall behind her, but she stayed there, looking at the tile in front of her with disgust.

"Let me try something a little less disgusting first," said Celestia. She bent her head awkwardly. Her horn would have touched one wall while her rump was up against the other, so she had to twist her head strangely as she bent down. She then licked the tile.

"Clever, but no cigar," said Discord's voice, echoing against the tiled walls. "My, the acoustics in here are fine. Perhaps you would appreciate a song? Siiiiinging in the Raaaaaaaaaain, I'm-"

"Discord, would you get to the point?" said Celestia.

"Hmph. No appreciation for the arts! But very well. As much as I appreciate seeing you bow your head and lick the floor, noble Princess, spit will just not do. But fear not, Moonbutt, pee is also not the answer. A quite different bodily fluid is required."

Celestia's eyes narrowed. "You are not the kind to be into blood, Discord."

"Heaven forbid!"

"Then what..." Celestia trailed off as she realized what it had to be. She put a hoof to her forehead and sighed. She was doing that a lot today. "Are all your puzzles going to be perverted and sexual, Discord?"

"Well... that depends on how one defines 'perverted'."

"Hah. Very well. But don't think I will forget this. Stone will be too good for you when this is all over."

"I don't understand," broke in Luna. "What fluid does he want?"

Celestia sighed again. "What fluid do you think? Cum, of course."

"Oh."

Both mares stared at the tiles for a while. There was no further sign of Discord, but they both knew he was watching them. Celestia hesitated, her ears flicking back and forth. She was currently not wet at all. So if she wanted to get some liquid to put on the tile and solve the "puzzle", she would have to touch herself. With Discord watching.

She lifted her front hoof off of the ground, then put it back down again.

"I don't like this, sister."

"I know. But I don't think we have any choice."

Now it was Luna's turn to sigh. "Yes." She lifted her hoof, and her eyes closed as she shut out the world around her. Her hoof went between her legs, rubbing slowly. She ruffled her wings, and her tail swished, as she conjured a fantasy, picturing a lover that pleased her. She had no lover currently, but she had hundreds of years of past relationships to draw on, so it wasn't hard to imagine a strong, virile stallion mounting her. She made a soft sound, and her hoof moved a little faster, the current reality fading from her mind as she lost herself in fantasy.

Celestia closed her eyes too, and put a hoof between her legs, but it was harder to lose herself. She could hear Luna beside her, letting out little moans, her breathing coming faster. And she was aware of Discord watching, even though she couldn't see him. Yet if she was being honest with herself, the idea of being watched wasn't entirely unappealing. A shiver ran through her, and her feathers roused and fluffed up, her wings opening slightly.

Her breath started to come faster, and her hoof was suddenly damp. She moaned softly and rubbed faster. Her hoof slid back and forth wetly, and soon there was enough liquid for her to "solve" the puzzle Discord had presented.

Relieved to be done, yet also strangely disappointed, Celestia lowered her hoof and smeared the wetness of her arousal on the tile before her. It began to glow a faint pink.

Luna made another low sound of pleasure, then lowered her hoof too, smearing her mare-cum on her tile. It too glowed pink. Both tiles shifted through a rainbow, brightening as they went; pink to orange to golden to green to blue to eye-searing purple, and then a door slid open before the alicorn sisters, and they dashed through it, towards whatever puzzle awaited them beyond.
