This was by the far the strangest mission Zero had ever been sent on in his life.

It was no secret Zero had been on some weird missions before. He knew this one would be dangerous, of course, like most ones he’d been sent to. An infiltration mission was always even more so when it had very little information aside from ‘some industrial laboratory performing some very unusual activity, and could pose a threat if not shut down’.

Fast forward to a few hours later, and Zero was currently searching around inside the building. But there were a couple of problems.

For one, Zero was admittedly a little lost. He had no idea where to look first, like some child looking for a lost toy. And two, his communication and navigation signals had both been reduced to static as soon as he stepped inside.

There was also no one else present in the building aside from Zero, which meant he was really all on his own.

Zero opened a door which led to another room. This one was larger than the room he was just in earlier, but just as seemingly empty. It reminded him of the training room back at Hunter Base, which used augmented reality technology to recreate various environments and enemies. But this place had none of that. Nothing but doors, walls and floor made of dark metal, illuminated only by soft, occasionally flickering lights on the ceiling. There was also a small security camera in the corner of the wall, but it simply hung low, indicating it was off.

The place was so quiet, aside from the occasional beeping of monitors and other computer systems, that Zero was startled when he heard a loud, robotic voice echoing all around him.

“INTRUSION DETECTED. INITIATE RESTRAINTS.”

Zero pulled out his Z-Saber, looking around for whatever threat was nearby. But there was no one else in the room except for him. Instead, he felt something clamp around and pull at his arm, then his other, causing him to drop his Z-Saber. As Zero struggled against his captors, which were long, metallic tentacle-like appendages with cuffs meant for Reploids attached to the ends of them snaking from panels on the ceiling, they lifted him up off the floor, leaving him dangling in the air. The Crimson Hunter continued to struggle and kick, but his legs were caught by similar appendages. They also had cuffs on the ends of them, and they clamped tightly around Zero’s legs.

Now fully restrained, Zero squirmed in his bonds, grunting in frustration. He could feel his blood thumping in his wrists from how tight the cuffs were clamped around them.

“What the hell…?!” Zero thought, wondering who or what was controlling this machinery as he continued to squirm. But he was startled out of his thoughts again when the same robotic voice sounded throughout the room.

“SUBJECT RESTRAINED. INITIATE ENDURANCE TEST PHASE ONE.”

As if on cue, a hidden panel in the floor opened, revealing a long, robotic arm snaking out of it, and raising itself up to Zero’s face. It had three claws, which were somewhat long and slender, but the tips were blunt, so they posed no danger of piercing through things (or in Zero’s case, his skin).

The robotic hand clacked its claws together a couple times, as if to warn Zero of what it was about to do. Zero raised an eyebrow in confusion, and reeled his head backwards a little, believing it to be a threat. Though, what the clawed hand did next left Zero even more confused.

The hand moved down to Zero’s belly, and dug its fingers into the soft flesh.

The Crimson Hunter jolted, and let out a gasp at the sensation. He looked down to see the robotic arm scribbling and rubbing its fingers against his stomach, the appendages pressing deep into the skin.

Zero felt laughter bubbling in his chest. It felt as if someone was playing with his vocal cords and pressure receptors at the same time. He bit down on his tongue to keep himself together. He could feel his chest convulsing slightly and his abs clenching and twitching as Zero tried to hold back his laughter.

After a few more moments, the claw finally pulled away from Zero’s tummy.

Zero was a bit surprised at first, but that soon turned to relief, and he took a few deep breaths to regain his composure. Though, his relief didn’t last for long, when the claw began making its way toward Zero’s side.

Zero heard the noise of the robotic arm moving from beside him, but his reaction came too late, when it began poking a finger against his side.

Zero jolted once more from the sensation, and he again felt laughter rising in his throat. “N-Ngh… S-Stop…!” He strained, stifling a giggle as he squirmed again, trying to get away from the fingers poking his side, but it didn’t deter the robotic hand from doing its job. This repeated for a couple of minutes, the claws switching between both of Zero’s sides to tickle, Zero struggling to keep in his laughter all the while, before it finally stopped.

Zero exhaled after holding his breath for the past couple of minutes, relieved that the claws had stopped poking at his sides. The Crimson Hunter resumed thinking of trying to find a way to get out of his bonds, but the automated voice from before spoke again.

“ENDURANCE TEST PHASE ONE COMPLETE. INITIATE TEST PHASE TWO.”

Right as the computerized voice spoke those words, the clawed hand that had been poking Zero’s sides just before began moving up to his chestplate. Zero couldn’t tell what it was trying to do, but he jumped slightly when he felt the claws tugging at his chestplate, feeling around for some kind of opening. Zero soon realized it was removing his armor. After some prying, the metallic hand soon found a hidden divot in the middle of Zero’s breastplate, and pried the two pieces off of his chest, letting them drop to the floor with an audible metallic clang.

With Zero’s toned chest now exposed to the cold air of the laboratory, he couldn’t help but shiver slightly, and blush lightly from being exposed like this. He rarely took his armor off, even in the safety of his dorm, so it felt weird for him to be exposed in the open. Zero felt like his dignity was being violated slowly, but it would be nothing compared to what was about to come.

Without any sort of warning, the robotic hand pressed its fingers into Zero’s solar plexus. He gasped again from the feeling, and could feel himself shaking trying to hold back his laughter. Exploring the Crimson Hunter’s muscular, powerful frame, the blunt, elongated claws prodded their tips into his skin, sliding upwards until they felt the ridges of the warrior’s ribs. The tips of the claws gently rolled in circles, toying with the artificial bones underneath Zero’s skin, and poking the spaces between each individual rib. They had slight difficulty in doing so, as his ribcage was protected by the layers of artificial muscle within the red android, and while it DID help dull the ticklish sensation a little, the warrior still found himself struggling not to crack and release pent-up laughter. Those claws were digging in deep.

Zero shivered as the metallic fingers continued to toy with his ribcage, biting down on his tongue. This could NOT get any worse.

If only that were true. Because a few minutes later, as the claws continued poking and tickling Zero’s ribs, another robotic arm snaked out from another hidden panel in the floor, which wasted no time making its way up to his taut stomach, and dug its fingers deep into the skin like the previous arm did many minutes before, which only intensified the ticklish sensation along Zero’s torso.

The Crimson Hunter jumped when he felt his pelvic armor being tugged at. Another pair of mechanical hands had emerged, and were attempting to pry the armor piece off like his chest plate. The armor came off with ease, and was tossed aside where Zero couldn’t reach it. Damn it, first his chest plate, and now his pelvic armor…?!

Having his ribs and belly tickled, along with his chest plate and pelvic armor being removed was already bad enough, but what Zero didn’t expect was something stroking across one of his buttocks.

He gasped and jolted from the sensation. A robotic tendril had risen from a panel on the floor, and it was targeting his butt.

The tendril’s sharp tip pricked at and scribbled over Zero’s buttcheeks, switching between each mound of synthetic flesh. Zero grunted and tried to squirm against the tendril tickling his butt in an effort to shoo it away. He obviously hated being touched there, but the tendril was persistent. It even dipped underneath to his taint right between his crotch and hindquarters to tickle the sensitive spot, and Zero squeaked from discomfort and ticklishness. He wasn’t sure what was worse- his butt being tickled or his taint being teased. Either way, it was humiliating to be touched in such a manner on one of his more private areas.

Zero hated this. Nothing was more important to him than his dignity and self-control. His demeanor projected professionalism, stoicism and might. Grinning like a fool would shatter all of that. He couldn’t let his dignity crack under these ticklish devices, not like this. But the incessant tickling at his ribs, belly and private places, the constant scratching and poking at his synthetic skin, was slowly making the Crimson Hunter crack under the pressure.

A chuckle occasionally leaked out through Zero’s teeth, his eyes shut tight in deep concentration. The ticklish sensations on his torso plucked apart the last few strands of his composure, one by one. He wasn’t going to last any longer against the tickling, evident from the rising giggles rumbling in his quivering chest.

Eventually, the final thread snapped, and Zero’s mouth shot open as laughter began to unleash from deep within him.

“Ahahahahahaha!” Zero laughed, having finally cracked from the incessant tickling. “S-Stahahap! No! Gahahahaha!”

The robotic claws and tendril ignored Zero’s demands to stop, and merely continued rubbing and wiggling against his tummy, chest, butt and taint respectively, this time faster than before, which made it more unbearable for Zero. The claw on his stomach occasionally poked and kneaded the sides of his belly as the other claw resumed wiggling its appendages between the spaces of Zero’s ribs, eliciting squeals of laughter from the bound Hunter.

“Nahahaha-No! G-Gehehehet away!”

Despite his predicament, Zero squirmed with all of his might, trying to get away from the ticklish tools attacking his chest and belly. His ponytail swayed back and forth as he shook his head from side to side furiously. But the devices kept on stimulating his sensitive nerves, his laughter echoing throughout the room. He was distracted by the continuous tickling at his belly, chest and ass that he failed to notice the tendril that had been tickling his butt just now slip between his cheeks, and the tip poked at the puckered hole that was his entrance. It was still clearly visible under the skintight bodysuit, and the tendril circled around the hole to tease it, making Zero’s entrance twitch and tighten.

Zero’s face became redder as his entrance was teased in combination with the claws tickling his belly and ribs. He couldn’t believe it- his asshole was being tickled!

After a couple minutes of his entrance being teased, the tendril finally stopped. The Crimson Hunter expected the tendril to pull away, but that was proven not to be the case, as the tendril started tearing at the portion of the bodysuit covering his asshole. The sharp tip tore it open with ease, until his anus was no longer protected by the spandex material. With nothing to shield it, the tendril promptly pushed against the puckered hole, inserting itself into Zero’s entrance, where it began pumping his insides. Worse, it used its tip to tickle the tight inner walls, making his insides spasm.

Zero laughed harder as soon as his insides were being tickled. It felt extremely uncomfortable to be tickled there, but his rectum was close to his genitals that it also felt pleasurable. The tickling against his insides sent waves of heat to his groin, which started throbbing and twitching with need. The feeling of need in his nether regions was hard to ignore, even in the midst of being tickled.

This went on for a few more minutes, until the claws finally pulled away from Zero’s tummy and ribs, and the tendril swiftly pulled out of his entrance with a slick pop. Zero gasped and panted in exhaustion, catching his breath after spending the past few minutes being tickled.

Though, his relief would not last for long, when two more robotic arms extended down from panels on the ceiling. They had buffers shaped like yellow, blunt triangles. Oh, no… Zero thought, his eyes widening slightly with horror, knowing what they were meant for.

Zero jolted a little when he felt something tugging at his shoulder armor. He looked over to see that the robotic claws were trying to pull off the armor covering his shoulders. He grunted in frustration, and tried moving his arms to swat them away, but his wrists were locked firmly in place by the cuffs. After some effort, the claws wriggled the armor covering Zero’s shoulder pads off, before prying off the pads as well, and dropped them to the floor to lay aside the Crimson Hunter’s discarded chestplate.

With Zero’s underarms now fully exposed, the arms pressed the yellow buffers into his armpits, no longer protected by armor, and began spinning rapidly across the soft flesh.

Zero burst into laughter once more, feeling the buffers spinning and digging into the warm curves of his armpits. “Ahahahaha! Nohohoho!”

Zero squirmed fruitlessly as the nerves in his armpits were being stimulated by the buffers, combined with the other two robotic arms tickling his stomach, ribcage and sides. He shook his head furiously as his body continued to suffer the excessive tickling. His concentration was deteriorating from the ticklish devices that he didn’t notice that the accursed mechanical tentacle had risen from its respective panel again, and reinserted itself into the Crimson Hunter’s rectum, pumping and tickling his insides at the same time. The sensation was unbearable. Fluids dripped out from Zero’s rectum the more the tendril pumped him, and he felt the heat rushing to his nether regions once more.

After a couple more minutes of enduring the torturous tickling, the devices seemed to decide to show mercy to Zero, and pulled away from his body, but didn’t retract into their respective panels (except for the tentacle that was just pumping him). Zero gasped in both relief and exhaustion, confused as to why the tickle torture had ended abruptly, but nonetheless glad it stopped.

“ENDURANCE TEST PHASE TWO COMPLETE. INITIATE TEST PHASE THREE. AROUSAL PHASE WILL NOW BEGIN.”

All feelings of relief faded from Zero’s mind as he heard the computerized voice again, and was replaced with dread. What did the voice mean by “arousal phase”…?!

Just then, Zero remembered the tendril tickling his butt and asshole earlier, and the arousal he felt from it. From that and the computerized voice’s words, it could only mean one thing…

Despite his exhaustion, Zero wasn’t deterred from trying to think of some way to break free of his bonds. He didn’t want to experience what the machine was going to do to him next, especially if it intended on shattering his dignity or harming him in some way. “Come on, damn it… There HAS to be some way to get out of this…!” Zero growled, wiggling his arms and legs against the cuffs to get out before the next round of tickle torture began, but his efforts were still no use.

What was worse is that the next phase of the tickle torture was already starting to begin. Out from the floor emerged a mechanical hand, but this one was more human-like compared to the claws that had tickled Zero’s chest and belly, having five fingers and having a shape similar to a human hand. It rose up to his groin, which had been alleviated of need since the buffers had tickled his armpits, but the mechanical appendage intended on changing that.

Zero looked down at the robotic hand, watching it intently as it sat just right below his nether regions. But he was completely caught off-guard when it dragged a finger across his groin, and it was agonizingly slow.

Zero shuddered and let out a trembly gasp from the feeling. He mentally berated himself for dropping his guard briefly- the third phase had the word “arousal” in it, he should have expected the mechanical extension to do this. He hated to admit it, but the sensation felt so damn good. His genitals twitched with need, wanting more attention. His folds could easily be seen throbbing underneath the Red Reaper’s bodysuit.

The hand took this as a sign that Zero was already becoming aroused, and decided to drag its index finger over his folds a few more times, starting back at the beginning each time it reached the end of the folds.

Zero shivered and blushed, grimacing. He absolutely hated this, despite a very small part of him wanting the robotic hand to keep going. He could swear he could feel something wet spreading between his legs, which he assumed was precum.

The robotic hand seemed to notice this, and decided to go further. Without any warning, it started pulling at the portion of the bodysuit covering the Crimson Hunter’s nether regions, and with some effort, ripped the spandex material away.

Zero continued to look down as his genitals were now fully exposed. On his groin sat a slit, which could only indicate the red warrior’s vagina. His vulva, soft and gently swollen with a pink flush, twitched with a desire to be touched and stimulated. It was almost cute from the way it pulsated.

As the android’s vulva twitched, the robotic hand gently inserted its index finger in between the soft folds with a soft squelch. Zero gasped, and he swore his face was reddening again. The hand pumped its finger at a steady pace inside his vagina, becoming soaked in cum in the process. It would continue doing this for the next ten minutes, until it began rapidly pumping at random for just a few moments, before returning to its usual pace, and repeating the cycle.

This bothered Zero even more, especially since he had no way of telling when the pumping in his vagina would speed up again. But all he could do was take it, even if his body was taking it unwillingly. He tried to remain quiet throughout the whole ordeal, but occasionally a small moan of pleasure would rumble from his chest.

The pumping gradually brought Zero to the edge of orgasm, feeling pressure building up in his nether regions. At this rate, with just a few more pumps, he would reach his climax.

However, right before he was about to orgasm, the hand pulled its finger out of his vulva. Zero’s eyes widened, and felt frustration beginning to wash over his mind as his orgasm started sliding out of his grasp, until his near climax lowered back down to an annoying throb.

Zero grunted in frustration from having been denied. Why did it have to stop at the very last second? His vulva throbbed desperately, crying out to be brought over the edge.

As if to answer the Crimson Hunter’s vulva’s silent cries, the mechanical hand rose back up to his groin, and planted two fingers against his labia. It carefully parted the lips like scissors opening, Zero wincing with pained arousal as his pink, silken folds parted with a wet crackle, webs of his own juices strewn between his tender folds.

Zero stared down at himself anxiously. He shivered as he felt the cold air of the lab wash against his exposed vaginal walls. Was the machine just going to leave his clit open the whole time…?

As if the answer the question hanging in his mind, another robotic extension emerged from the floor. What appeared to be the head of a small brush was attached at the end of it, and on the head sat soft, yet prickly bristles, resembling a paintbrush.

And it was aiming for Zero’s folds.

With the lips of his vagina held apart by the mechanical hand, the tendril with the brush stroked over the tender flesh of the android’s pussy, the bristles poking softly into the walls.

Zero let out a cry of shock and discomfort and jumped, feeling the brush against his sensitive inner walls. He attempted to squirm to avoid the brush, but alas, it was futile. The brush kept on stroking against his vulva, subsequently becoming slick with fluids, but the bristles didn’t lose their effectiveness one bit. They even teased the hooded button of the Crimson Hunter’s clit, the nub quivering in response.

Zero shuddered and grunted as the brush kept on teasing his sensitive folds. Even worse is that the sensation tickled, and he found himself fighting back giggles, and trying not to let his frown twitch involuntarily into a grin.

Unfortunately, Zero WOULD end up laughing one way or another regardless, which would be proven the case soon.

Another two robotic tentacles snaked out from below, very much similar to the one that had pumped him earlier, but they had a different purpose… Rather than tickle his butt or his puckered entrance, they targeted his ripped pectorals, right on his firm chest, and began scribbling their sharp tips over the muscles.

Zero would be able to take the tickling on his pecs, if it weren’t for the fact his pectorals happened to be his most major weak spot.

The Crimson Hunter’s resistance shattered almost immediately upon his pecs being tickled, and he burst into laughter once more.

“AHAHAHAHAHAHAHA! NAHAHAHAT THEHEHEHERE!”

Zero’s laughter was louder than before due to his major weak spot being tortured. The tickling on his vagina was already bad enough, but the ticklish sensation on his chest was arguably more unbearable. At least the feeling of the brush teasing his vulva was more tolerable than this.

The tendrils were persistent at tickling the android’s sensitive pecs, swirling their tips around the edges and centers of them. They twitched slightly in response to the abuse they were forced to endure, the nerves underneath stimulated to no end. Who knew a muscular and well-built Reploid such as Zero turned out to have such ticklish muscles?

After a few minutes of this, the tendrils moved to the areas Zero’s nipples were located on his pecs, which were hidden under the bodysuit, and scribbled over THOSE instead.

The Red Reaper’s nipples turned out to be not only ticklish, but also an erogenous zone, as proven when Zero began moaning with pleasure in between his laughter. The tickling at his clit certainly wasn’t helping, either. An artificial tongue coated in some kind of lubricant attached to another tendril even snuck between his asscheeks and started licking his ticklish asshole, the ring of muscle puckering and twitching against the fake tongue as it was basted and coated with the cold lubricant. It felt as if someone was rimming the red android, except it was being done by a tongue that was nowhere near organic.

It wasn’t long until Zero felt an orgasm cresting again. The bristles of the brush certainly helped stimulate his needy folds, and he knew he was going to cum very, very soon.

When the brush pushed its bristles even deeper into his swollen pussy, the Crimson Hunter’s hindquarters grew tense all at once, his vaginal walls convulsing and compressing with tight, high pressure arousal, before he felt his lower body relax and release all tension in heavenly bliss as his pussy released a messy squirt of fluids. The brush kept tickling at his clit and the tentacles continued teasing his nipples to let the android ride out his orgasm for as long as he could, fluids continuing to drip freely from Zero’s vagina, until he came down from his high.

Sensing Zero had came, the brush pulled away from his vulva, bringing strings of his juices along with it, and the rest of the devices retreated back to their respective panels, his laughter gradually fading until it came to a stop. He panted in post-orgasm exhaustion, feeling a mixture of shame and relief from having just came. He felt very undignified by this point, but he barely cared about that anymore. It was finally over.

At least, that’s what he thought. His vulva was still engorged, a sign he was more sensitive from orgasming, and the machine wouldn’t let that go to waste.

After a few moments passed, another robotic hand came down from the ceiling, similar to the one that was still holding Zero’s vaginal lips apart, except it was holding what looked to be a black cloth. It promptly wrapped it around Zero’s eyes, blindfolding him. It was a method of making it difficult for their victim to predict what the machine would do to them next, increasing their suffering. After applying the blindfold, it retracted back to its respective panel.

Once the Crimson Hunter was blindfolded, his vision was surrounded by nothing but darkness. He was still able to hear and speak, but it didn’t do much to relieve his unease. Anticipation was pecking at his mind for the machinery to return to fondling and tickling his sensitive body, though he would have no way of telling what tools his captor would use next, which would make it harder to brace himself for further treatment.

The worst part is, Zero’s clit had already began to throb with need once more, despite having came not too long ago.

The android found himself holding back a groan as he tried to ignore the throbbing in his loins. He needed to focus on escaping, but his needy, moist pussy would not stop nagging at his mind. Zero’s mind was busy running back and forth between escaping and his twitching vulva, that he didn’t realize he was rolling his hips, but it wasn’t clear whether it was to relieve himself of his arousal or to persuade the machine to touch him again. As this was happening, very briefly, images of his clit being massaged by a paintbrush and other various tools flashed in his mind.

Zero’s train of thought came to a halt when a mechanical sound was heard from below.

Zero ceased rolling his hips, and shook his head in an attempt to shake the images of his needy clit out of his mind, looking down toward the source of the noise despite the fact he was blindfolded at the moment. He was so lost in his thoughts that he lost track of time- how long was it since he first came?

That didn’t matter to the Crimson Hunter any longer, because something was rising from a panel in the floor again. But what was attached to the end of the tendril wasn’t a paintbrush or mechanical hand.

It was a long, white feather.

The tendril slowly moved the feather underneath Zero’s loins. Due to Zero’s blindfold, he couldn’t see the feather, but he could clearly hear machinery moving, and he knew that a tendril was going to do its job on him again. The android couldn’t do anything but brace himself for whatever tool was going to tease him next.

However, his guard was dropped when something delicate brushed over his clit, and he gasped softly with pleasure, his cheeks turning red again.

Despite not being able to see anything at the moment, Zero looked down at his loins. Something… something was touching the folds of his pussy again, but it didn’t feel like the bristles from the paintbrush from earlier, which gave him a small sense of comfort, but it didn’t make the Crimson Hunter feel any less bothered and undignified, not to mention the fact that the feeling was similarly ticklish.

Zero soon recognized the soft, delicate yet ticklish sensation. The feather was stroking over his swollen clit.

The blush on the android’s cheeks grew deeper, and he grunted with frustration (and, regrettably, pleasure) as the feather licked over his engorged vulva, the folds visibly twitching as the plumage teased it. Zero tried everything in his power to ignore the tickling on his clit and suppress the giggles rising in his chest. The sensation would have been more bearable if his vagina wasn’t swollen and hypersensitive from coming recently, but unfortunately he would not have that comfort, and it just made the feathery feeling on his folds that much worse and harder to ignore.

A couple minutes had passed since the feather began teasing Zero’s clit, and an involuntary grin had started forming on his flushed face, and quiet giggles rumbled from his chest. He found himself awestruck and appalled that a mere feather was able to reduce him to giggles, and it made the red Hunter realize just how ticklish his pussy really was (even though the paintbrush had already tickled his vulva before).

The feather continued tickling the Crimson Hunter’s vagina, incessantly and with no end in sight, gradually being covered in his juices. Occasionally, it would swirl its soft tip over the hooded button of its captive’s clit, making the android moan softly and shiver in between giggles.

Eventually, Zero felt another orgasm starting to form from the non-stop tickling from the feather on his loins, coupled with his hypersensitivity. He was going to come at any moment now. Part of him wanted the feather to stop just so the last bits of his pride wouldn’t be broken- he didn’t want to find out if he could orgasm from such a pathetic tool, but at the same time, the red Hunter wanted this to be over-with so he could finally be free.

Zero was gradually approaching his peak. He was so close, just a few more strokes, and he would come once more…

But right before he made it over the edge, the feather stopped stroking, and pulled away from the red android’s folds slightly, just mere inches away from his crotch.

Zero gasped, visibly caught off-guard. He tried rolling his hips to persuade the feather to touch his folds again, but nothing happened. The feather remained in place, not moving an inch. “Tch… Dammit…!” Zero grunted, gritting his teeth in frustration from being denied again. He could only writhe in his bonds with desperate need as his near-climax was reduced to a dull, nagging throb. He groaned, realizing he would be stuck here for even LONGER if the machine was not going to let him cum.

It wouldn’t be until Zero felt a delicate sensation over one of his buttocks that he gasped again.

As the same sensation was felt across his other buttcheek as well, the Crimson Hunter’s cheeks turned into a deeper red. He recognized the feeling- it was the same light, feathery touch that teased his clit earlier.

It dawned on Zero when he put the pieces together. The machine released two more tendrils with feathers, and was stroking them over his shapely rear.

Zero wasn’t enjoying any of this one bit, especially when his hindquarters were being touched by nothing more than a couple of measly feathers. To pour salt in the wound, the feather on his clit began licking over the throbbing folds again, which twitched in response.

The android felt giggles rising in his chest from his clit and buttcheeks being tickled. He tried to suppress them as he bucked in his bonds, and all that came out was a shaky moan. Zero cursed at himself internally for making such a lewd sound, but that ultimately didn’t matter as the feathers kept stroking across his private areas.

Up and down the feathers swept, all over their captive’s trembling, ticklish rear. The soft fronds of the plumage stimulated the nerve endings under each cheek, releasing tingling sensations through Zero’s ass, before one of them swept between his cheeks and made contact with his puckered entrance.

The sensation of the feather teasing his anus sent tingling shocks through the android’s nerves. His asshole had been tickled before by one of those tentacles, but having a feather sweeping over it was arguably even more humiliating for Zero. To add even more insult to injury, a pair of mechanical hands stretched his asscheeks apart, revealing his exposed asshole and giving the feather easier access to it.

Zero’s ass trembled, feeling his own puckered hole clenching and twitching from the fronds of the feather stroking all over and around the ring of muscle. It didn’t help that he could feel the cold air of the lab washing over his anus (part of it was due to it being previously lubricated by that damn tongue) in addition to the feather. He wiggled his backside as much as he could while he tried to swallow the rising giggles in his throat in an effort to shoo the feathers away from his asshole and buttcheeks, but his movement being restricted by his bonds meant he couldn’t do much to wriggle about. He couldn’t even get the feather teasing his clit to stop, which was dripping with precum onto the floor below him.

“W-Whoever ihis doing this, s-stohop it, NOW…!” Zero snarled in the midst of the feathers teasing his delicate areas, unintentionally letting a few giggles slip through. He could also feel the involuntary grin returning to his face. It was getting much harder for him to fight against the urge to laugh with every passing moment. But he HAD to resist, even if his clit was being stimulated by the machine.

Speaking of his clit, the Crimson Hunter started to feel a pressure in his nether regions. He was nearing climax again. Although Zero would never admit it, a part of him was relieved that perhaps this would end, finally. Hoping for the best, he let the feather do its job on his vulva, bringing him closer and closer to his peak… Yes, just a bit more, and he would FINALLY be able to cum…!

In just a few moments later, Zero felt a heavy wave of pleasure wash over his groin. He knew at this point he was just about to orgasm. Bracing himself for the sweet release from his loins, he moaned lewdly, awaiting his climax from the stroking of the feather, until at last, he reached his peak.

But he didn’t cum.

Zero’s eyes widened behind his blindfold, pleasure quickly replaced with confusion. He had reached the edge, so why wasn’t he cumming…?!

The red warrior couldn’t understand what had happened. It was as if all stimulation had stopped, and all the pleasure that had built up from his orgasm suddenly disappeared. He could feel cum dripping from his loins, but there was no pleasure, no release- only an exploding frustration as he came without an orgasm.

Zero cried out with sexual frustration, and thrashed like a wild animal in his bondage. He had to reach his clit, had to get pleasure. That was the only thought in his mind as he twisted and squirmed and pulled against every one of his restraints, rolling his hips in vain, hands pulling as hard as they could to break free from the cuffs clamped around his wrists, but getting nowhere close to his twitching folds. He was stuck in place, and it would remain that way for him for a long time.

Eventually, Zero gave up, gritting his teeth, all tension leaving his exhausted muscles and panting through his nose. His vagina had dribbled out all of the remaining cum, but he didn’t manage to get any pleasure from it. His body shook and twitched in frustration, fists clenching and unclenching. All of the tickly devices had retreated back into their respective panels, even his asscheeks were no longer being spread. But this didn’t make it any better for him.

“B-Bastards…” Zero hissed, scorn obvious in his voice. For a brief moment, he thought that this machine and who or whatever was controlling it were even worse than Sigma or Vile. At least those two numbskulls never subjected him or anyone else to such cruel and humiliating treatment.

The only thing Zero could think about in the silence now was the throbbing need in his loins, and desperation to cum. As much as he hated to do it, he tried thinking of his clit and inner folds being stimulated by various tools, whilst rolling his hips, wishing for the machine, anything, to stimulate his pussy to try and make himself get off, but of course, there was no use in doing so.

Little did he know, however, is that his darker thoughts and desires would come true.

Because as Zero hung there limply, the mechanical hand that had held the lips of his vagina apart when the paintbrush teased him snaked out of its panel once more, and inserted two of its fingers into his vulva. Its fingers were cold, which made the feeling much worse. Zero let out a breathy and shaky gasp, quivering as the hand started massaging his inner walls. His nerves were hypersensitive from orgasming, it wouldn’t take too long for him to climax again. He failed to suppress moans of pleasure as the hand kept on massaging his swollen pussy.

Zero got close to orgasm again. His tongue lolled out of his mouth, his face redder than his armor. He wouldn’t last long against the hand’s stimulation, his nerves quivering from hypersensitivity. And he was right, because just as he was right near the edge of his peak, the hand inserted all of its digits inside his vagina, and scratched at his g-spot.

That final touch was all he needed to finally orgasm for the second time, letting out a loud moan of pleasure as cum shot out of his vagina like an explosion of white, splattering onto the metal floor.

Even after he came twice already, Zero’s vulva remained painfully swollen, an indication that he was now even MORE sensitive than before, and any further stimulation would be much more intense than the last.

Zero moaned in exhaustion, and closed his eyes, his chest rising and falling as he gasped and breathed heavily.

Though, Zero wasn’t given much time to rest, because when he heard the computerized voice once again, he realized with horror that this torture was far from over.

“ENDURANCE TEST PHASE THREE COMPLETE. INITIATE TEST PHASE FOUR. COMMENCING TICKLE HELL AND MILKING PHASE.”

No, this couldn’t be happening… ANOTHER phase…?! Just what kind of hell is this…?!

The Red Reaper heard yet another panel opening from the ceiling, the same mechanical hand that had blindfolded him snaking back down. This time, however, it was holding a different object- a black leather strap with a buckle at both ends. In the middle of the straps was a red, silicone ball, fit for inserting into one’s mouth.

The hand quickly inserted the silicone ball into his mouth, and it fit snugly, prohibiting the Crimson Hunter from protesting.

“Mmmmph…! Mmmphmmh!” Zero tried to speak, but the gag hindered his ability to speak anything coherently. All he could do was let out muffled grunts and growls as he continued to struggle in his confines.

Zero jumped when he suddenly felt the bristles of what felt like a comb and hairbrush sweep up and down his thighs. He squealed as he continued being tickled by the comb and brush, and as he did, all of the tools that had previously tortured him resumed tickling the various other parts of his body, including his asshole (which the tendril had started pumping in yet again) and pectorals, but his vulva was left alone.

As if things couldn’t get any worse, two robotic extensions with the same triangular buffers under Zero’s armpits arose from the floor, and targeted his soles, and began spinning rapidly over them. Even though they were still shielded by armor, the receptors underneath were still sensitive, which didn’t help in dulling the ticklish shocks.

As this was happening, something rose from the floor, but it was far different than the other tools. Instead, it was a milking device, and inside was a wheel with countless bristles attached to it. Zero would soon learn that particular device is the reason why the current phase was referred to as the “milking phase”…

The milker attached itself to Zero’s nether regions, just right below his vagina, and the wheel immediately began to spin rapidly over the hypersensitive flesh of his folds.

“MMMMMMMHMMM! GRHMHMHMHM!” Zero squealed loudly and moaned with pleasure as his clit was tickled along with his whole form, clenching his teeth down hard on his gag. His entire body convulsed and spasmed, shaking his arms and legs against the cuffs as he tried to resist the relentless ticklish devices all over him, stimulating every nerve in whatever area they were currently tickling. Every synapse in Zero’s brain was screaming at him to fight back, to somehow get free, but no matter how much he tried to struggle, his confines would just not let go. “ARGHGGHHH!! HMMMFFGGHHHH! MMHMMHM!”

From the excessive stimulation at his clit and the unbearable tickling all over his body, he soon came into the milking device, which sucked up every and any trace of his fluids into the tube it was attached to. The device was tightly and securely cupped to his groin that not a single drop of fluids escaped.

But the milker didn’t cease. The wheel of bristles within it was still rolling every single one of them against Zero’s vagina. It was programmed to never stop, and would remain that way forever even if he continued cumming. He could feel each and every bristle scraping against his folds.

With Zero’s excessive head shaking and constant shouting, the blindfold eventually fell off from his eyes, finally allowing him to see again, and the gag popped out of his mouth as the room was once again filled with his helpless shrieks of laughter.

“AAAAHAHAHAHAHA!! NOHOAHAHAHAHA! PLEASE! PLEASE STOP!” Zero cried out between laughter and gasps, feeling himself losing his breath from the merciless tickle torture and stimulation he was enduring. By this point, he had given up trying to struggle. His muscles were worn out from thrashing around in his bonds, and he had no other choice but to give in to the tickling. His head was the only part of his body Zero could move by now, and he could only shake his head furiously in the midst of his torment. His irises had also shrunken down to pinpricks, indicating just how desperate and panicked he was. The artificial tentacles tickling his pecs also moved to his nipples again and traced over them, causing him to moan with pleasure even more loudly while laughing at the same time.

His nerves were becoming so sensitive from orgasming more than twice now that even as Zero laughed louder and louder, he continued cumming. He orgasmed HARD merely from being tickled and his nerves subsequently became more and more hypersensitive, to the point where his orgasms were so close together that he felt like air was being taken out of his lungs. The machine practically forced the Crimson Hunter’s mind to equate tickling with sexual pleasure that he couldn’t stop orgasming. Yet, as a Reploid, he couldn’t faint or die. He couldn’t even struggle because the cuffs and his exhaustion rendered him powerless.

There was no way out of this torture. The tickles on his body and stimulation to his nether regions were endless, and they just kept coming.

This was more than just tickle hell.

This was orgasm hell.

“HAHAHAEEEEEIIIIIEEEEE!” Zero squealed, the loudest he ever had in his life. “I-I CAHAHAHAN’T B-BREATHE!”

Zero wasn’t lying. The stimulation was just too much that he could feel his systems going into overload. Warnings began to cloud his vision, warning him of too much sensory input, of overheating, of lack of air. His lungs burned like fire, and his stomach and chest ached horribly. His laughter caught in his sore throat, and nothing but strained wheezing came from Zero’s vocal cords, darkness beginning to cloud his vision as his systems were starting to shut down.

The last thing Zero saw before passing out were the tendrils tickling at his perky nipples, and he came one last time.

……………………………………………………….

Zero’s systems started to come back online after what seemed like ages. He first became aware of the room he was in hours ago, and could faintly make out his own scent from the excessive sweat trickling down his body from the intense tickle torture he had endured earlier. After Zero let a minute pass to regain himself, he realized he wasn’t being held upright anymore. In fact, his limbs were finally free from the cuffs, and he was laying on his back on the metal floor, facing directly at the ceiling. By his side, laid his discarded chestplate, shoulder armor, shoulder pads and pelvic armor.

Zero also noticed his hand felt moist. When he looked down at himself, his own hand was right over his nether regions, still soaked with fluids from cumming excessively hours ago. He realized he must have been subconsciously masturbating while he was still hazy, but he was unsure whether he had been jerking himself off while he was still unconscious or not.

Zero tried to get up, but groaned in pain from how sore his muscles felt. His entire body felt like jelly, his legs trembled, and he could barely move. He couldn’t remember how long he had been tickled and stimulated for, but he knew it must have lasted for at least a few hours to make the Crimson Hunter’s muscles so sore and tired.

Zero spent the next several minutes resting on the floor to regain some of his energy, trying not to let his own exhaustion catch up with him and knock him out cold again. But in his dazed state, he already found himself subconsciously masturbating again, rubbing his nether regions until he came. His clit still felt unreasonably horny, and a sexual urge within him demanded for him to pleasure himself. Rolling onto his stomach so he can put more pressure on his clit, he plunged his hand into his pussy and resumed masturbating to completion a few more times, thrusting his hips to gain maximum pleasure on his enlarged, swollen vulva, before finally feeling satisfied, and mustering up enough energy to get up, stretching a little and wiping some leftover sweat and other bodily fluids off his body. His legs still trembled from being sore and they actually buckled, but even that didn’t make him stumble and collapse when he reached down for his chestplate, shoulder armor and pads and pelvic armor, and snapped them back on to their proper places. Now fully armored again, Zero picked up his Z-Saber which he dropped earlier, but before he placed it back into the sheath on his back, the memory of himself being tortured and forced to orgasm mercilessly by the automated devices from before flitted through his mind.

Believing the devices would try to capture him again, Zero fired up his Z-Saber, and put himself into a defensive stance, this time prepared to fight back against the tools that humiliated him earlier. But they didn’t activate.

Confused, the beam from Zero’s Z-Saber vanished, and he continued searching around the room, thinking he was being tricked. He waited for a few more moments, but the cuffs never came out to bind his wrists and ankles, nor did the ticklish devices snake out of their panels to torture him again.

With nothing else to do, Zero put his Z-Saber back in its sheath, and walked over to the door on the opposite side of the room to continue searching around. Before he opened it, though, he found himself thinking about the torture and constant stimulation the devices had put him through earlier again, and he felt heat rushing back to his nether regions. But why? That machine was torturous and vile, he shouldn’t be feeling any form of sexual arousal just from thinking about it!

Just who or what made those torture devices, and what were they THINKING when they made them? Zero recalled the automated computer voice saying something about an “endurance test” before, so perhaps whatever that machine was, was meant for experimentation to study how long a Reploid could last under continuous torture and genital stimulation.

Still, it was a rather indigenous method for testing all the same, especially for Reploids. Zero couldn’t help but think: What would X say if I told him about this?

Very briefly, however, a small part of Zero wondered what he could do with a machine like that- one that he could control, and NOT tickle and make him orgasm against his will. Maybe, just maybe, something like that wouldn’t be so bad to have after all.

Zero shook his head to try and forget the thought that had just run flitted through his mind and what he’d been through, and to ease his concern. He still had a mission to focus on, after all. Even though his muscles were still sore at the moment, he could take it. Though there was still the possibility of the machine damaging his internals from what it did to him. His rectum felt quite sore as well. He made a mental note to call for X to come pick him up should he be unable to make it back to Hunter Base on his own, and to call a medical team to examine him for any potential injuries he may have sustained from the machine. But that all comes second. Right now he needed to get out of this hellhole as soon as he can.

Zero pulled out his Z-Saber once more to carve a large hole through it for him to enter (which was locked shut), and began making his way further into the lab, never looking back once.

He can only hope there wouldn’t be any other traps that would subject the Crimson Hunter to the very same torture hours before.
