Thou'rt warned.

Gaping Chasm

Water sloshed as Daring Do slipped deeper into the tub, submerging herself up to her chin in the beautifully warm water.

The tomb chamber was now completely candlelit for lighting as Prismatic Sprint and Daring Do relaxed, taking advantage of the large array of items that Testacles had been buried with; while the box of novelty soaps had long since been eroded by the passage of time, and there was no source of water to fill the massive bathtub they'd found, they did have Evening Glitter, who would provide for what was quickly becoming a somewhat trivial cost of an internal climaxing; a quickie for the omnipresent candles, and an experiment in "diamond dog style" for magically warm water later, and the intrepid explorer and assistant were relaxing after a rather strenuous and messy few days; rigorous sex over the last few hours aside, it had been five days since they'd last seen a trace of civilization, and much further than that since the last place with faculties for an actual bath.

Daring Do watched her flaccid cock bob about in the half-opaque water as she soaked, the "temporary" organ remaining permanent until they got out, in case they needed to buy another wish from Glitter. She saw movement in the water beneath it, and felt a hoof playing with her vagina, Prismatic grinning and sinking low to stretch across under the water and play with her lover.

"Not a bad expedition, right?" Prismatic said brightly. "We came here looking for treasure and ancient history, we found love and some very exciting experiences..."

"And me," Glitter said, coasting by as she flicked through a leather-bound papyrus tome filled with Neighgyptian lettering that she'd found; according to the title, it was a complete ledger of every single child of Testacles, both daughters and sons.

"And you," Prismatic agreed. "You're going to love it out there, the world has really changed since you were put in here."

"Does the Neighgyptian Empire stretch from ocean to ocean like Testacles decreed it would, forever more?" Glitter asked.

"Not really," Daring admitted. "The Neighgyptians kind of died out, and now the biggest country in the world would be... Equestria."

"Never heard of it," Glitter remarked.

"It's very nice, very cosmopolitan," Prismatic said, scrubbing herself idly with an ancient bath sponge. "Plenty to see and do, not like here in this tomb."

"Oh, I haven't been here that long," Glitter said. "When I'm inside my lamp, it's hard to say how much time's passed. I did think Testacles hadn't called on me for a while, but..." Glitter shrugged. "Doesn't matter, I was able to finish my book while I waited, then you guys summoned me. It all worked out."

"You enchanted this tomb, though?" Daring asked.

"Yep," Glitter said. "And a bunch of other stuff, too. It took about sixty thousand ponies to build this place over ten years, about a quarter of them died doing so, and I think... twenty mares got impregnated by Testacles to pay for the enchantments, structural permanence spells, and traps."

"Traps?" Daring asked. "Like the one in the corridor outside?"

"Yeah, I know, right?" Glitter closed her tome, looking proud of herself. "Testacles was like "I want a wall of spikes, but instead of spikes, I want cocks, so I can watch thieves get fucked senseless," and I made the magic penises and the mechanism. Good thing you guys didn't set it off."

"Uh, we did," Prismatic said quietly.

"Oh? How'd you get out, then?" Glitter asked. "I'm pretty sure I only made that doorway wide enough for one, no fly zone..."

"I got stuck in there," Daring said, dunking her head briefly and giving her mane a vigorous scrubbing with her hooves, turning the water around her milky white as the dried cum in it was washed out.

"That's ridiculous," Glitter dismissed. "How would you be standing here, then?"

"I satisfied all the cocks and the door opened."

"Impossible," Glitter said. "No mortal pony should be capable of that, and yet, you're walking mere hours after you did it?"

"Daring Do is a legend in her own lifetime," Prismatic pointed out.

"Ah, for Archaeology and treasure hunting," Daring clarified. "Not whoring."

"Truly, we live in the future," Glitter mused. "Well, I suppose that explains the positively champion stamina you two have demonstrated so far. Even Testacles had to plan out his wishes and economize a little."

"Wait, what?" Daring asked. "You mean we can consolidate wishes?"

"Well, up to a point,"Glitter said. "You can wish for a thing, and specify sub-clauses like how you want it to be, done, when, what should be included... Testacles was lucky to find me, and clever enough to use me."

"Not that I didn't enjoy it," Prismatic said. "But I am a little cheesed off that you sat back and let us start a marathon just to run a bath."

Glitter waved a hoof. "You never asked – I didn't tell Testacles until he asked either, you know. He was halfway through a dungeon when he figured it out. Whew!" Glitter waved a hoof at her face and smiled. "I thought I'd seen everything, but that was a new level of hatefucking."

Daring blinked. "Hatefucking?"

"You know, when you're super mad," Glitter said.

"That doesn't sound like fun to be on the receiving end," Prismatic said.

"It wasn't. It was a Neighgyptian dungeon, not a happy romance chamber like this one," Glitter said.

"That's disgusting," Prismatic said.

"Rules of the wish just say someone has to get filled up," Glitter pointed out. "Nothing about consent, that's just gravy. Now, on a more pleasant note," she said, rubbing her hooves together. "Do we have any more wishes and holes to fill, or should we move on?"

Daring and Prismatic looked at each other, and nodded. "Yeah," Daring said. "We should move on."

"Alright," Glitter said, drifting over to the wall. "There's towels and a change of clothes next to the tub, free of charge; consider it a goodwill gesture for not explaining all the rules of the game in advance." She reached out, and grabbing a bracket for a torch, yanked it down.

The tomb shook, and the previously seamless wall split and began to separate, parts sliding up and down until a square portal to darkness stood there. Glitter bowed, gesturing at it.

"When you're ready, the exit awaits."

* * *

The torchlight flickered as the unusual trio trotted along; the tunnel was straight and narrow, sloping downwards ever so slightly.

"So, where does this go?" Daring asked.

"Caverns beneath the Pyramid," Gitter said. "They were there when the pyramid was built, and Testacles didn't want to wish them away. Said they added character. Or maybe he wanted to make me magically reinforce the foundation as revenge," Glitter said, shrugging. "He did spend wishes to generously riddle the caverns with traps, though," Glitter said. "To dissuade would-be thieves trying to get in the back door. Don't worry though," Glitter said. "Getting you out alive does mean I'll be leading you around the traps or telling you how to beat them in advance."

"Good," Daring said. "I've run from enough boulders in my time."

The tunnel ran out, and darkness waited beyond, the room so deep and vast it swallowed the little light the torches and Glitter could produce. The air was dry once more, marking a no-fly zone once again. Daring and Prismatic stood on the edge of the vast chasm, watching as Glitter shot out into the void, waving her ghostly hooves.

The chamber pulsed and began to come to life with a faint, red glow; outcrops of crystals and gems riddled the walls and ceilings, forming pinpoints of red light that stretched for miles.

Daring turned around and flinched as she saw thick strands of white covering the path ahead. A poke revealed the strands were soft, squishy, and a little sticky, although the dust of time had done a lot to cancel the adhesive properties of the web.

"Spiders," she said. "Why'd it have to be spiders?"

"Hmm, there was a bit of a dire spider infestation down here in Testacles' time," Glitter said. "Although, if it's been as long as you say... I rather doubt they've had many visitors. They should have moved on, or died out.

"Dire spiders?" Prismatic asked, leaping up and grabbing the web to tear it down and out of the way.

"Like a regular spider, but Dire," Glitter asked. "Big. Somewhat venomous. Or is it poisonous?" Glitter shrugged. "I can never remember."

"Can we not talk about spiders?" Daring asked, shaking her head and looking a little pale in the red light. "They give me the willies."

"Ah, so someone else has given you a willy before," Glitter said brightly. "I knew it!"

"No, no," Daring said, holding up a hoof. "I mean they-"

"Behind you!" Prismatic shouted, pointing.

Daring Do spun around, and finally sensed a presence; she looked up and saw a monstrous creature hanging by a long thread from the underside of the pyramid far above. It was like a pony, in that the head, torso and forelegs were similar – it had a perfectly-styled purple mane, two ears, an ivory coat and hooves like a pony. But that's where the similarities ended; everything from the hips down merged with a shiny, chitinous black shell, turning into a violent hourglass shape before forming a large abdomen, with another eight legs extending from the hips and top of the abdomen.

And the equine head was something nightmarish, the elegant mare's face marred by rows of tiny, beady eyes and a jaw filled with sharp, sharp fangs.

"Oh no," Daring said quietly, taking a step back. "Oh no."

"Welcome to my parlor," the creature hissed. "So good of you to descend from on high. You look like you have travelled far, you must be weary. I have little beds that beg for use; if you'd like to rest a while, I'll snugly tuck you in!"

"What are you?" Daring asked.

The creature detached itself from the thread, and dropped to the ground with a whud that belied her weight, in contrast to her grace. She leant over close and pouted at the frozen Daring Do.

"Such rudeness," she tutted. "What, indeed. Who am I? I am Arachne," she declared. "I live here. This is my home, as it has been for generations, ever since the first Broodmother wove a web of stone to shield us from the world beyond."

"Fascinating," Glitter muttered to herself.

"What is?" Prismatic asked.

"Well, Testacles... experimented a little with paying for wishes for variety's sake," Glitter said, folding one hoof and pointing with the other. "Arachne here must be the ultimate result of his attempt with a dire spider. Did not see this coming."

"Oh. My god." Daring said, horrified, looking at Glitter. "How can you fuck a spider?"

"You wound me," Arachne said, an expression of mock-hurt on her face as she placed a hoof on her breast. "Am I not an attractive creature?"

Daring turned around again, and held up a hoof. "I would literally die before I called you attractive."

Arachne sighed, and held out her hooves, shrugging. "I try to be civil. Broodmother as my witness, do I try." Her eyes glittered and she grinned maliciously, teeth glinting. "Let's see if you mean exactly what you say."

Daring squeaked as Arachne's forehooves and legs spread out and she lunged forward to grab her. But the only impact came from behind her as something shoved her hard, and she fell on her front.

She rolled over to see a very generous view of the underside of Arachne's abdomen, where a vibrant blue mark shaped like a diamond was visible on the chitin. She looked down to see that the spider-mare wasn't turning around, and that she was clutching somepony else...

"Prismatic!" Daring shouted.

"Professor!" Sprint shouted back. "Go! Run while you can!"

Arachne regarded the squirming mare in her clutches idly and shrugged.

"A pony is a pony," she said, before biting Prismatic in the neck.

The younger mare screamed in pain, but it didn't last long, trailing off to a contented moan, and the struggling stopped. Arachne turned around and freeing her fangs, smiled at Daring.

"Sprint!" Daring shouted. "Let her go, Arachne!"

"Now, why would I do that?" The spider-mare asked. She turned to the edge of the chasm, and winked at Daring with half of her eyes. "Don't go too far away now, darling," she said. "I'll be back for you later."

Arachne tensed her legs, and sprang into the void.

"No!" Daring shouted, lunging forward to jump after Arachne. She was caught by translucent purple hooves as they hooked themselves around her forelegs.

"Whoa, slow down there, Professor," Glitter asked.

"Glitter!" Daring exclaimed. "Let go of me! She's got Prismatic, I have to go after her!"

"I'm sorry, darling, I can't let you do that," Glitter said. "At least, not from here – have you forgotten it's a no-fly zone? I have to get you out of here alive."

Daring blinked, and squirmed out of the genie's grip, jumping back onto solid ground. She looked around, spotting the damaged web that had blocked the way. The path had to lead to Arachne and Prismatic. It just had to. She'd get herself caught by another spider-pony if that's what it would take to get her friend back.

To get her lover back.

"Hang in there, Sprint," Daring growled as she started running.

* * *

Prismatic came to gradually; the light here was dimmer, the nearest crystals still very far away, and the red light not carrying as far as would be comfortable. She groaned softly; her neck was killing her.

She tried moving, and found no joy, as she was fixed in a spread-eagled position, on a slight angle. The only part of her that was still free was her head, and even then, only enough to look around; not enough to, say, bite through the web restraints that had strapped her hooves to the web.

She was pretty stuck.

"Ah, you're awake," a familiar voice said. Sprint looked down to see glowing red pinpricks for eyes in the shadows. They rose up, and Arachne was illuminated in all her spidery glory, white coat a deep red in the light.

"What do you want?" Sprint asked, teeth gritted. "Are you using me as bait? Forget it!" she declared. "I told the Professor to run. She won't come back for me!"

"Bait?" Arachne asked. "Oh ho, I hadn't thought of that. No, no, not bait."

"Then what? You're going to eat me?"

"Mmm..." Arachne smiled coyly. "Yes. Or maybe not. Depends on how you thought I was going to eat you."

Prismatic began to squirm as she approached, and closed her eyes in terror. And gasped as she felt a very unexpected, but welcome, sensation on her groin. She looked down to see Arachne lapping at her marehood, humming gently to herself as she worked. Daring couldn't help but moan in pleasure as she was taken down a familiar path for the umpteenth time today.

"I am no fool, darling," Arachne said, pausing. "I know when I am not the first. But so recently...?" Arachne smiled. "Could you, perhaps, be hot for teacher?"

Prismatic blushed, faced with the idea of confessing to a third party. And a stranger she barely knew, at that. Arachne laughed.

"Well, well," she said. "Whatever her skill, I imagine she can't do... this?"

Arachne lowered her head again, and a long, slender tongue snaked out and- oh, stars. Prismatic went limp, head hanging back as Arachne did her thing. If only Daring could do that. Prismatic closed her eyes, imagining Daring doing the same thing, just swirling around, and around, and-

Prismatic paused. It had stopped very suddenly. She opened her eyes, planning to sit up and ask what the big idea was. Instead, she saw a rather familiar sight.

Her eyes had adjusted to the poor light, and she could make out another web, much like the one she was lying on, some distance away. Like hers, the other web was also occupied, although the occupant was a bit on the thin side. Because they were dead, a whole skeleton still stuck to the web. Countless tiny strands of web dangled from the pelvic bone and bottom of the rib cage like a threadbare mane, falling through the groin and down to the ground below. Webs like that were only used when a spider wanted to climb down, right? Now why would that be? Webs that small would only be used by-

The penny dropped, just as there was a pinching sensation on the most sensitive of locations; Prismatic raised her head to see Arachne nibbling on her button. She looked up Prismatic's torso and winked.

"Something to help things along," she said. "I've tried saying "don't fight it", but it just doesn't work – can't imagine why," she confessed, as she clambered up onto Prismatic's web properly; all eight legs stood with absolute confidence on the web, and Prismatic found her voice lost as her groin burned with a deep heat, dripping fluid.

There was a slithering sound, and something long extended from Arachne's abdomen on the underside. The view was cut off as Arachne leant forward, biting Prismatic on the neck again, this time more gently.

"You'll be a great mother, I can tell," she whispered, running a hoof up Prismatic's torso.

Something hard and slightly rough slid into Prismatic's slit, and penetrated her deeply in a crude imitation of her experiences so far. Arachne pumped her abdomen a few times, poking Prismatic's insides. The mare wanted to scream, but her throat was cold and all she could do was stare into Arachne's serene face as it went on.

Satisfied, Arachne arched her back, tilting her head as she moaned, and the slender object that joined them suddenly flared it's head, locking them together as a fluid began to pour into Prismatic.

Arachne bit her lip, and Prismatic discovered why as something large suddenly pressed into her outer folds, within the tube. An egg, wider than Daring ever had been, even at her most erect. It was stopped for a little while, but Prismatic felt the impact of more eggs colliding with the back of the one that was stuck, and pressure building up. There was a bit of give, and then it suddenly slipped past, pressure beating what resistance Prismatic's near-virgin vagina could provide.

Soon, it was a constant flooding sensation, more and more lumps slipping through easier; Arachne was enjoying herself, eyes shut and bouncing up and down and running her hooves through her mane in pleasure.

Prismatic tried to hate it. But something – the venom, or a deep reproductive urge – made each egg feel like a reward; every time another one entered her womb, an achievement. She began to drool, even as she fought to stay focused. Her stomach tightened, and started to grow uncomfortably full, but the eggs kept on coming, and even the full sensation was starting to turn Prismatic on.

Help, Prismatic thought weakly.

There was a whip-crack, and Prismatic snapped out of her trance, looking at the source. Even Arachne had stopped, but being unfamiliar with it, she had no idea what to expect.

In the darkness, a familiar pegasus, wings outstretched for balance, was swinging through the air, with the end of a long corded rope – a whip – clenched in her jaw, the other end wrapped around a sticky web. She reached the end of her swing, and somersaulted through the air, the motion causing a fifth limb to be visible briefly against the magenta light following her.

Arachne tried to stand up, and Prismatic cried out in pain as Arachne tugged on her own ovipositor's anchor. The spider-mare was herself trapped, a victim of her own plot to keep Prismatic pinned down. She stood up as high as she could instead, back arched as she kept her hips low and abdomen angled up to look at the source of the sound.

And so she saw Daring Do land heavily on the back of her abdomen, clinging to her back as she scrabbled to get a better grip.

"That's my girl you're fucking," Daring growled.

"You have courage, little fly," Arachne said, relaxing. "But nothing else. You did not even bother to acquire a weapon?"

"Oh no, I've got one," Daring said, scrabbling up a little higher to sprawl on top of Arachne's abdomen. Arachne frowned – she had all four hooves in plain sight, but something warm was still blocking her spinneret...

"Glitter, spiders count, right?"

"They do indeed," Glitter said, hooves folded as she glared at Arachne malevolently.

"I wish for Prismatic Sprint to be free!"

This time, it was Arachne's turn for the penny to drop, and for something foreign to thrust itself into her depths. Daring grunted as she bottomed out inside Arachne's spinneret without hesitation or foreplay. She wasn't even sure if the organ was designed to even support such an insertion.

But after what Arachne had done to Prismatic... she didn't care. She humped vigorously and without mercy, stirring up Arachne's insides with her magical endowment as the spider-mare screamed and thrashed under the onslaught; but thanks to her ovipositor, she was trapped, and could do nothing but take it.

The venom was wearing off for Prismatic – she was able to scream too, in a mixture of pain and pleasure as her own insides were stirred up by the ovipositor; she felt eggs shatter as the organ speared them and crushed them, and the pressure on her belly lessen ever so briefly before it was suddenly replaced with a fresh flood of eggs from Arachne; with the beating her own guts were getting, Daring was inadvertently pumping more eggs into Prismatic.

Shattered shells grinded within Prismatic, and yolk from shattered eggs began to dribble out from around the ovipositor as the cycle of destruction, filling and general violation went on; Daring could feel herself getting close on top, and she motioned to Glitter.

"Spiders... are big, right?" Daring gasped. "Lotta... lotta space to fill!"

Glitter winked. "I gotchu fam," she said, her horn glowing. Daring felt the weight at the base of her groin intensify, and started to feel the underside of Arachne's abdomen as her now oversize testicles slapped against it. The act only intensified the pleasure, and Daring grunted a herculean grunt of effort as the back of her balls suddenly became slick with juices from her own cunny. They tensed up, visibly shrivelling, and Arachne joined the chorus, howling as inequine amounts of fluid started to force their way into the wrong hole.

At the very bottom, Prismatic screamed too; the force behind the eggs was now massive, causing them to shatter in the ovipositor and inside her womb as her belly was stretched to capacity; it was now a question of what would break first; the ovipositor, or her.

Arachne and Prismatic's eyes both bugged out, and as pressurized streams of cum began to shoot out from Arachne's spinneret around Daring, Arachne's howling took on a different pitch, and there was a wet sound underneath her.

Her voice broke, and she sagged to the side, her connection with Prismatic now broken even as eggs began to shoot out of the ragged remains of her ovipositor, smashing against the insensate, swollen mare with the other end of the reproductive organ jammed inside her, green yolk dribbling out as she was coated in more of it.

"Payment made, wish granted!" Glitter exclaimed quickly.

There was a flash of purple and the bonds that held Prismatic to the web vanished, although the mare was now too weak to move. Daring pulled herself out of Arachne's behind with difficulty thanks to her (still large, but much shrivelled) balls, and left the spider-mare to ooze cum and web from a ruined hole as she ran over to Prismatic.

"Sprint!" Daring exclaimed, pulling Prismatic free. "Speak to me!"

Prismatic focused on daring and grinned weakly. "I told you to run."

"You didn't say where," Daring said, hugging Sprint awkwardly. "I ran all the way here."
