Blind Challenge 18

Twilight and Luna investigate dark energies in and around Canterlot. (Archmage-verse)

------------

Twilight frowned down at the strange markings on the street. Luna stepped up to her side, both of them looking down at the scarred cobblestone. "Thoughts?" Luna asked quietly. Twilight glanced at her before leaning in a little closer.

"I can't say to be sure." She muttered, frowning more intently at the strange markings. "There's certainly something ahoof here, I just can't say what it is for certain."

"I wonder what it could be. Seven thousand years alive, and I've never seen or felt anything like this." Luna's voice was concerned, but not distressed. As far as Twilight could tell, no one had suffered any injuries from this. At least, nothing major. Some slight fatiguing, to be certain, but Twilight wondered if the victim was all that angry. From what she had gathered speaking with the poor mare, the entire experience had actually been somewhat enjoyable. Twilight straightened and rubbed the bridge of her nose with a groan.

"There's most definitely something going on here, and it involves the night. Have you spoken with her lately?"

"Not for some time." Luna admitted, blushing slightly. "Though not for lack of trying. She's been mysteriously absent."

"Well whatever this is, she's involved." Twilight was able to conclude that much. There was a resonance about the area, one she was relatively familiar with. She had felt it quite a bit over the past few years. She was the Archmage, Canterlot's main authority on all things magic, and adviser to the princesses on matters of the arcane. She was only forty years old, still a very young unicorn, but world-wise enough to know a lot about the world and how it worked. Luna was her lover, her confidant, and her partner in many ways. They lived together, slept together, and even solved mysteries together.

Mysteries like the recent spree of vicious rapes in and around the city. The victims all didn't seem to mind, but Twilight wondered if there wasn't some drug involved that was making them enjoy what was being done to them. For the past four days, the guards had been stumbling upon ponies here and there throughout the city that were exhausted and claimed to have been violated in the most intimate of ways. None of them recalled their attacker, or any specific details of the incident, other than it was surprisingly enjoyable.

"Where to next?" Luna asked, shaking Twilight from her reverie. Twilight dropped her hoof and glared down at the markings on the cobblestone once more.

"I'm going to try to follow the energy trail. Hopefully, it'll lead me to whoever or whatever has been doing this."

"It may be that the night is acting of its own accord." Luna mused, following Twiilight's gaze down to the mark on the cobblestone. "If so, she may not want to be discovered..."

"True." Twilight sighed and tore her gaze away from the mark. "But we need to at least discover what's happening. It may be that somepony's manipulating the night."

"Not likely." Luna scoffed. "The only ponies strong enough to do that are you, me, and Harbinger. But we both know he can't do it."

"Well..." Twilight began walking away from the mark, towards the yellow tape the guard had used to mark off the site of the latest attack. "We had no idea Harbinger was that powerful. It may be that somepony's out there that's powerful enough to accomplish it. Let's face it, I'm strong, but it stands to reason that I'm not the absolute strongest in Equestria."

"True..." Luna sighed and followed Twilight. Together, the both of them ducked under the tape and began to walk down the street. Twilight was following the resonance she felt in and around the stone, and Luna was following her. The resonance came and went, but she caught it whenever it went weak. The two of them were mostly silent as they continued down the street. Twilight was focused on the resonance, so Luna had to guide her around some obstacles. After a half an hour of searching, Twilight lost the trail in the middle of Canterlot's main park.

"It ends here." She stopped, looking around the clearing with a slight frown. There were no landmarks nearby. They were, quite literally, just in the middle of an open, grassy space. Luna pulled up beside her, both of them looking around with frowns on their faces.

"That's odd." Luna's keen gaze pierced the late-evening shadows, but Twilight could tell she saw nothing. "You'd think we could find something here."

"You'd think." Twilight looked around once more before studying the grass. "This is so strange... I could have sworn this would lead us somewhere conclusive. Ugh, I'm getting a headache." She rubbed her eyes once more. Just as she was about to abandon the search and return, though, something caught her eye. She paused and padded a few short steps away to where she had seen it. It was a patch of pale gray in among the green grass, and it seemed oddly out-of-place. Twilight brushed a hoof over it to discover it was a stone, roughly the size of her own hoof. Curiously, she lifted it from the grass, turning it over.

"Luna." She beckoned the princess over. "Look. It has the same mark as the street."

"That's true." Luna took the stone from her, holding the mark up for her own inspection. "It seems this chase wasn't a complete waste. We've discovered this much at least."

"It's so odd," Twilight took the stone back, looking closer at the stone. "It looks like a major apex of a nineteenth arch. I could almost do an invocation with this."

"Give it a try." Luna nudged her side. "We should be safe here, even with a nineteenth arch invocation."

"Do we have a hundred yards?" Twilight asked, looking around. Sure enough, the closest tree appeared to be over a hundred yards away. She could invoke this diagram here and now. "Might as well." She frowned at the diagram before her horn began to glow. The diagram etched on this stone and back on the street were the exact same, and both belonged to a spell-form. She didn't recognize it, but that didn't mean it wasn't legitimate. She began to cast the spell with the diagram at the apex.

"Woah!" Luna gasped. All around them, the grass had vanished. It was replaced instead by a dark, shadowy ground. "Twilight! What the heavens?!" Twilight dropped the stone, gasping as she whirled around. They had been teleported out of Canterlot! Twilight could tell. There was no more magical interference in the air. She couldn't feel Canterlot's unique signature all around her. In fact, she couldn't feel anything. "Twilight!" Luna was panicked, her eyes wide. "Twilight, I don't have any magic!"

"What?" Twilight tested her own magic. Sure enough, she couldn't summon anything. Her magic was gone! Luna's too! "This isn't good." Twilight grimaced as she pressed closer to Luna. "I can't dispel this."

"This is no partition." Luna turned around, both of them covering one another's backs.

"No, I'd have my magic if it was. This is either some negation field or we're no longer on Equestria. I can't feel a thing."

"Let's not panic." Luna took a deep breath. "We've handled worse."

"Heh. True." Twilight smiled as she lifted a hoof to touch the pendant on her chest. As long as she was with Luna, she could handle anything. The two of them were indomitable. The moments stretched on, making Twilight wonder what the purpose of this place was.

"Should we explore?" Luna asked after a few minutes.

"Maybe. This is a nineteenth invocation, so we should be inside of a field. Let's go one hundred yards." Twilight turned around to follow Luna, but then something brushed against her hind leg. "Gah!" She jumped and whirled around, looking for whatever had touched her. Luna gasped and did the same. "Were you just touched?"

"Yes. I don't like this." Luna whimpered, her eyes narrowed suspiciously at the landscape. Twilight could hardly see anything with all the blackness.

"Nor do I. Come on. Guide me backwards. I'll look behind us." Luna nodded and gingerly took the end of Twilight's tail in her mouth, giving her a gentle, guiding pressure. Twilight walked backwards, keeping a wary eye on the ground and the sky. Nothing came up behind them, and Luna continued to guide her backwards. After a long while of walking slowly backwards, Luna stopped.

"I hit the edge."

"Okay." Twilight breathed. "We're still within a nineteenth invocation, then. We never really left Canterlot."

"Odd. We just can't use magic here. I wonder why."

Twilight froze. "I think I know why."

"Hmm?" Luna turned around, and she froze as well. Behind them, the ground came alive. Long, dark tendrils rose in front of them, undulating and swaying back-and-forth. Twilight felt something brush against her again, causing her to jump. Another tendril had just brushed against her hindquarter, very close to a place only Luna knew.

"Twilight..." Luna said cautiously. "I think... This is what's been assaulting those mares."

"Agreed." Twilight frowned at the dark landscape come alive. "It's getting frisky. It almost touched me... Down there."

"Me too." Luna frowned. "We don't have any magic, Twilight. We can't defend ourselves."

"I know." Twilight looked up at Luna, her expression helpless. "What do we do?"

"The only thing we can do." Luna fixed her with an intent look. "We have to beat this thing at its own game."

"I figured as much." Twilight sighed and smiled at Luna sadly. "I love you."

"I love you too, Twilight. No matter what happens." Luna rushed forward then, pressing her lips against Twilight's. Twilight sagged into the kiss, preparing herself for what was to come. She didn't have much time. Another brushing presence pressed against her thigh, high on the inside, hardly an inch away from her marehood. That made her gasp into the kiss, her mouth opening inadvertently. Luna shared the expression, their breath mingling in the space between them. Twilight almost lifted a hoof to fight the encroaching tendril away, but found she couldn't. More tendrils had wrapped around her hoofs, slowly spreading her apart. She felt her weight lifted off of her own legs, and Luna began to shrink away.

"Luna!" Twilight called out, trying to fight against the tendrils. They were awfully strong. Twilight herself was pretty fit for a unicorn. She had discovered that with mental strength came physical strength, but even her muscles were no use against the hold the tendrils had on her. She and Luna were both lifted from the ground and into the air, their legs spread out in an X shape. Twilight wasn't pulled far away, just far enough that Luna couldn't be touched, even if she was free. The tendrils began to brush against her in more and more places, sliding over her thighs, her stomach, and even her neck. She shuddered as one tendril wrapped around her neck, hugging the strands of her coat a little tight for her tastes. She could breathe, but the sensation of strangulation was there. As she began to writhe in their hold, the tendrils on her thighs grew more and more bold.

Her eyes shot open as she felt the first one probe her. Something round and slick pressed against her marehood, putting a steady amount of pressure on her. She closed her eyes and grit her teeth, inhaling a breath through her bared lips.

"Twilight." Luna called out to her. "Relax. We've done worse."

"I know." Twilight whimpered. "It's just... This isn't you."

"Well. Think of it as me." Luna's voice was thin and high. Twilight could tell she was being subjected to some pretty intense sensations just then as well. Twilight wanted to cry out for her, but she dared not open her mouth with the tendrils roaming about as they were. Almost as if on cue, one of the bolder tendrils pressed to her lips. She closed them over her teeth, turning her head away.

To no avail. "Omph!" Twilight gasped as her jaws were suddenly forced open, and her mouth invaded. The black tendril slid all the way to the back of her throat in one solid motion, forcing Twilight to gag. She coughed around the intruder, sending a spray of saliva into the air. Being a lesbian, Twilight had never performed fellatio. Having something so solid in her mouth was moderately disgusting. It pulsed about inside of her, curling and twisting in some truly sickening ways. Twilight fought to keep from losing her lunch.

The tendril against her crotch finally penetrated. Her eyes snapped open, and she moaned long and loud against the one in her mouth. The thing was thick, thicker even than the strapon she and Luna had used now and again. It was borderline painful. She flexed around it, praying it didn't go any deeper. Only it did. Twilight felt the tendril reach places deeper than she had ever tested, and go deeper still. She was almost completely invaded by now. The tendril in her mouth was pushing in and out now, hitting the back of her throat with a bit of force. She felt saliva pour out of her lips and onto her coat, drenching the purple strands there.

Luna wasn't doing much better. She had been flipped upside-down, her marehood exposed to the sky. Two tendrils were taking turns plunging into her and pulling out, opening and closing Luna's most private area lewdly. She was screaming against her own oral tentacle, her eyes clenched shut with either pain or pleasure. Twilight couldn't tell which. Then she saw a third enter the picture. Eyes wide, she watched as it pressed against Luna's tailhole, teasing her with rapid flicks. Luna's eyes opened, and she squirmed in the hold these things had on both of them. To no avail, of course. With a louder scream than any previous, Luna's anus was penetrated, and by the way she writhed harder, it was awfully deep.

Twilight felt the first teasing bit of pressure press against her own anus. She flexed immediately, squeezing the tentacle that was already inside of her. She and Luna had never experimented with anal, since neither of them were terribly turned on by it. If this thing had its way with her, it would be her first. Twilight screamed against the tentacle in her mouth, but only managed a guttural choking sound. She flexed harder and harder until her muscles screamed in protest. But still the tentacle pressed against her anus, spreading the tight flesh bit by bit. Tears streamed from her eyes as it finally pressed inside of her.

And by the stars, it actually felt good. Unlike the other tentacles, this one actually seemed to be rather gentle. It massaged her anus, rubbing against the other tentacle through the thin wall of flesh separating her vagina and her ass. The pressure was addictive. Twilight hated to admit it, but she began to enjoy herself. Watching Luna go through the same thing, she was wasn't all that angry. In fact, she felt her orgasm approaching.

"Pwah! UGH!" Twilight spat as the tentacle left her mouth, allowing her to grunt as her orgasm ripped through her. Shuddering, Twilight felt a long, thin stream of liquid spray out of her vagina, spattering lewdly against the writhing black tentacles. She had never squirted this much before, not even with Luna. Spittle dripped down her chin, adding to the mess on her coat, and cooling on her flesh. Luna's eyes were closed, but she was no longer screaming. If anything, her moans were suggestive and encouraging. Twilight watched as Luna emitted a thin stream of her own feminine ejaculate, the liquid arching upwards thanks to her awkward position. It fell to the tentacles below them wetly, making Twilight's chest heave with a renewed wave of desire.

"Okay." Twilight grimaced, looking around at the tentacles. "Now we're warmed up." Her lips curled into a devious grin.

"Show us what you've got."

------------

"Princess! Archmage!" Twilight's legs gave out underneath her. She collapsed into the grass as the black world faded from around them, taking the exhausted tentacles with them.

"Luna! Twilight! Call the medical corps, now!" Celestia's voice came to them through a haze, and Twilight managed to lift her head enough to look up at the solar princess. "What happened?!" Celestia leaned in, her expression worried. Twilight smiled up at her, her aching core still flexing in the absence of penetration.

"You know the assaults happening all over the city?" Twilight asked, still rather delirious in her post-orgasmic haze.

"Yes, I asked you and Luna to investigate them. But that was a week ago!"

"A week? really?" Twilight chuckled and closed her eyes. "Odd... I thought it was three hours ago..."

Darkness took her then. Sweet, welcoming darkness.
