Finitevus and Scourge arrived the opposite side of the shrine Knuckles was on. "It's best we slowly make our approach" The green hedgehog was told by the doctor. "He might be dazed and out of it, considering how much of the drug his system has taken in. He'll hardly be fit for a fight"

"That's good t'know, cause I ain't a fan of this guy's punches" Scourge smirked as he tailed the white echidna around the stone structure and tugged the lapel of his jacket, like the big shot he was in his mind. "I like a good fight, but I think I like the thought of humiliating the guardian while he's helpless even more"

Oh and humiliated is what Knuckles was sure to be in due time. The red echidna was twitching on the ground, panting and had pearly white puddles surrounding him, some painting his body in globs and streaks. His sight was turned to the blue sky, the only sound he could hear was his semi heavy breathing and an intense ringing in his ears. What just happened? His mind begged the question, but the concern didn't last long when another hot flash of arousal ignited every one of his nerves in a pleasurable fire he couldn't even begin to describe.

A massive impulse of lust and the need to amplify the pleasure struck the guardian like a tornado picking up a weak kitten. He barely had time to contemplate rationally before he was writhing and panting in heat as he rapidly stroked his still firmly hard dick "Aahh, ahnnh- fuck~" 

After just coming up on the final bend of the shrine, Finitevus paused and stopped Scourge in his tracks too. "Hear that?" The white echidna asked while sporting a maniacal grin, looking quite pleased from the moans a short distance away. "This should be easy. I don't think he can even control himself. But regardless, keep your caution"

"Heh, you don't gotta remind me of that Doc. I know not to underestimate the red guy. I'm ready for anything" The hedgehog responded and if the look on Fini's face said it all, the mad echidna was approving of his answer. He got a nod from the doctor and they continued.

Soon they saw the sight of the usually fierce guardian, going to town on himself like there was no tomorrow. Scourge wanted to laugh his ass off at the spectacle of Knuckles moaning up at the sky, dripping with his own cum and squirming like he was in the most intense bliss imaginable. "Whoa... Damn he's really going for it"

Finitevus rolled his eyes and shifted his walking speed into more of a brisk pace, while Scourge was  to incentivised to keep up as they approached the horny red one. 

Knuckles just shot another load and was panting heavily after the release, though his hand still remained playing with his dick. He didn't know how many orgasms he's had, but the cycle was intoxicating. He was lying there, just waiting for the next surge of arousal to take him away again. It couldn't even occur to him on his own that something was seriously wrong about what he was doing. Knuckles was wrapped up in too much mind numbing pleasure for his own good. But that was until something else broke through the ringing in his ears. 

Did someone call his name? He blinked his eyes and sat up quickly in his rapidly depleting lucid state. They landed upon the insane white echidna and Scourge walking up to him, the pair stopping just a few feet away. "Wha?" He looked at them confused and dazed out of his wits, unable to make a correlation.

"I see my formula is doing it's work well" Was all Finitevus had to say for it to finally click and make sense in his younger foe's head. He actually stepped back when the other snapped. 

"Y-you!" Knuckles growled a menacing vicious growl, his hackles raising as he realized he had been drugged by the madman. "I'm going to pound the ever living daylights out of both of you!" He a yelled, angered and flustered with his muzzle ablaze in a clear display of total abject humiliation. He just came to the full realization he was a horny mess masturbating all over himself because of these two standing in front of him!

"You may try, but I doubt you're a match for either of us in that current state" Scoffed Finitevus, which made Knuckles snarl and lunge forward at him, the guardian throwing a rather desperate and unfocused punch. "What a pity!" 

Scourge was impressed to watch and see how prepared the doctor was for something like that. Finitevus seemed to just oh so effortlessly remove a ring form his wrist and used it to trap the guardian's fist as he dodged out of the way! 

"What?! No!"  Knuckles shouted in rage when the ring suddenly closed and clamped around his wrist! He saw it coming but only when it was too late! "Agh! Finitevus, what the hell is this?!" He yelled after yanking his arm a few times, finding he was unable to pull himself free. But even stranger was how the ring never so much as budged when he struggled.

A wicked smirk crossed the doctor's muzzle, he was glad to share with Knuckles his latest warp ring variation. By the dumb look on Scourge's face, he could use the explanation as well. "These are special rings I've created, by modifying the technology of an original warp ring." The caped one began as he stood back to view Knuckles who was growling and desperately trying to tug himself free from the tight grasp of the golden halo clutched around his wrist. It was quite an unforgettable sight, the guardian's muzzle blushing a burning red, obviously under the embarrassment of his hard cock being completely exposed to two men he despised.

Finitevus was actually lost in the thoughts the red echidna's body influenced in his mind. He was getting stiff under his cape and was idly touching himself, amused Knuckles couldn't see what was being prepared for him. "Mmm,  yes" He chuckled in a fur raising way Knuckles found especially creepy. "Struggle all you want, the ring remains stationary like any other warp ring... However" The white echidna pulled his right hand from under his cloak and casually pushed his captive's arm to the left. "I've hacked the gravitational properties and found a way for the user to be able to move them around at their own whim."

Knuckles' eye's widened when the evil doctor moved his arm in the ring so effortlessly, but they narrowed quickly as a new wave of anger crashed over him. "So this is how you're going to capture me is it?! Well you're forgetting I've still got three free limbs and I can kick both your asses with two tied behind my back!"

"Always such a feisty child" Finitevus tsked before turning and addressing Scourge who was standing back a little. "Scourge, what do you make of the guardian's current display? Come get a closer look and let us know what you think."

"Heh, bout time you let me in on the action" Scourge grinned as he stepped forward and made the trapped echidna considerably more uncomfortable as he looked him straight in the eyes before scanning down his entire body. Eventually his eyes locked onto Knuckles' hard on and he smirked. "Nice t'know my dick is bigger than his"

That made the red male's temper flare up and he instantaneously threw his free fist at the green hedgehog's face! "WHAT THE FUCK DOES THAT EVEN MATTER!?" He roared, but Scourge dodged his blow. "WHY DID YOU TWO EVEN DO THIS TO ME!?" He threw another punch, though it was sloppy given the predicament provided him limited flexibility. "BASTARDS I'LL MAKE SURE YOU WONT LEAVE THE HOSPITAL FOR MONTHS RAAAHHH!"

Finitevus watched as Knuckles kept punching and the hedgehog kept dodging while wearing a cheeky yet sinister grin, snickering the whole time he was being threatened. The white echidna was waiting for the opportunity and could see the volatile guardian's actions getting worse each time he tried to strike, until he was simply trying to grab at Scourge. "LET ME GET A HOLD OF YOU AND I'LL SHOW YOU WHAT'S FUNNY ABOUT MY FIST DOWN YOUR THROAT! RAAAHHH!"

"Alright, enough games!" The doctor intervened by shoving Scourge away and swiftly captured Knuckles free hand much the same way he did with the first restraining ring. "There... Now we can begin what we came here for"

Great, this was easily the worst situation Knuckles had ever found himself in and he now realized all his struggling and pulling was doing nothing. "Dammit, Finitevus. You're sick... What are you creeps plotting?" He growled, still blushing with his eyes now cast to the ground. He cringed when he saw the mad doctor's hand reach forth and felt it glide upon his cheek. Something suddenly smelled sweet and musky, an aroma encapsulating his senses and almost calming him. He looked up at Finitevus with his eyes and shivered as that hand glided down along the underside of his jaw. He saw the white echidna smirk while he pressed his thumb lightly to his lips. 

Knuckles blinked as he was unsure what was happening, that sweet musky smell more powerful now, as if it were right under his nose. Wait a minute, he realized there was something wet and slippery on the mad one's thumb. For some reason he couldn't stop himself from darting his tongue out, a salty flavor greeting his taste buds when he did.

Scourge spectated from the side and he was starting to feel himself become aroused after the announcement of the real fun. The hedgehog's sheath stirred, beginning to swell as he watched with surprise at what was unfolding before him. It was strange but it seemed Knuckles' rage was subsiding and the red echidna looked like he was getting hazier by the second while he timidly licked Finitevus' thumb, almost even suckling on it. 

"Like my pre-cum on your lips, Guardian?" The doctor spoke up, smirking  as he stepped back to gauge his young enemy's reaction. 

Knuckles felt swift mortification embrace him all over once again after he learned what Finitevus was smearing on his lips. He wanted to be more angry than he'd ever been before, but it felt as though that mega ton of rage was being astoundingly suppressed by another feeling entirely. His heart pounded in his chest, butterflies of nervous swarms fluttered in his stomach with the worst realization of all. He could only think about the taste and it made him so incredibly horny he began to pant and sweat. Scourge and Finitevus both grinned at him while they watched his cock dripping and throbbing near verge of orgasm without even being touched. "Nnghh, hhnnn what di- aah ahhn Whatdidyoudotomee-eenngh?!" Knuckles grit his teeth, his legs crossing tightly as he tensed up to stave off the orgasm.

"It's my advanced lust enhancing formula, dear guardian. You've had quite a lot of it so every little touch should practically paralyze you with pleasure. I'm actually really amazed you were able to hold back just now, but we've not even done anything to you yet" The scientist chuckled and  continued to tell Knuckles his assessments. "This formula also works on your mind, as I've pinpointed how to influence arousal and sexual craving through taste and smell"

"Ugh, you son of a bitch" Knuckles didn't want to believe the words he was hearing as he was standing there sweating and trembling with his arms up in the air, his hard cock engorged and leaking a steady stream of pre cum. He could faintly smell his own arousal and it was beginning to make him hazy again. "Hnnnnh ...wh-why?"

Rather than simply answer, Finitevus pushed his cape back to reveal his hard seven inch cock. Knuckles' eyes immediately locked onto the pulsating tool, his lust warped mind zeroing in on the dripping pre-cum glistening in the sunlight down his shaft. His head was filled in seconds with the memories of the taste of it and he licked his lips as if the salty flavor would still be there. 
 
"I see you're eager, Knuckles.... Not to worry though, you'll be enjoying such inconceivably blissful release soon. Over and over again until my cohort and I are done with you" The doctor beckoned Scourge over with his index finger and the hedgehog gladly approached with a smirk and his fully hard dick in hand. 

"Sup, Red? Ready to suck cock and love it like a good slut?" Scourge asked, snickering in a manner to mock the hung up red guardian. 

"Grrrr fuck you! I'll never do anything like that, you filthy thug!" Knuckles lashed out, nearly barking at the green and evil counterpart to Sonic. "I'll bite it off if you put that thing anywhere near my face!"

Scourge did feel a little rush of nerves at the threat and seeing the sharp teeth of the echidna. Man he was one angry small fry that actually could intimidate him to some level. Right now for instance, did not seem like a good time to push his luck by putting his dick in that guy's maw. "Yeah? Well uh... I'll ah... hmm"

Finitevus saw Scourge was getting cold feet after Knuckles managed to have another outburst of rage through all his accumulating lust. He couldn't blame his partner in regard, Knuckles was making quick switches from hopelessly dazed to infuriated on the flip of a coin. "Step aside Scourge, and observe while I run a test..."

Scourge muttered but stepped to the side and folded his arms to watch the doctor run whatever test he had in mind for their captive. "Alright, but I ain't so sure that formula was as strong as ya say" The hedgehog added his two cents only to be ignore by the white echidna.

"Ahng, I'm not a test subject god dammit!" Knuckles yelled. Finitevus carried on and grabbed the restraint rings to start slowly pulling the guardian's arms down. "Ehnh, stop this! I wont do anything you sickos want so forget it and leave me be!" He continued to protest, but was getting more worried the lower Finitevus moved his trapped hands. Soon he was forced to bend over and he found the sight of the doctor's cock at the tip of his snout, the scent of arousal flooding into his nostrils. "I'm gonna kick your-! I'm gon-gonna-hnnng!" His intense rage stopped and he began squirming where he was locked in place. "N-no, ge-get it awa- aahhh~"

"The fuck is happening with him?" Scourge scratched his head, his brow raised with confusion. "He was just all gung ho wantin' to punch our skulls in, and now he's literally drooling on your dick!"

"Oh yes, the formula is working just fine" Finitevus licked his chops as he looked below at Knuckles who now seemed to be entranced at the sight of his pulsing rod inches from his face. "Given these reactions, it's safe to theorize Knuckles is trying to fight it. But I believe the formula is too strong for him. It's only when he's not being stimulated, that his anger breaks through."

"Oh yeah? So that a good thing or...?" Scourge asked, concerned about the well being of his glorious cock in the long run of things. "I mean, If there's a chance he can be angry while my dick's in his mouth..."

Finitevus chuckled and cut him off "Oh don't worry, I've planned precautions no matter how this played out" He assured the other before pulling out a device from his cape. "This ring gag will probably be more fun for you too, I imagine" With that, Finitevus stepped back and covered up his rock hard shaft to observe the effects on Knuckles once more. After all, he was a scientist and it felt like his duty to test his subjects thoroughly.

After a moment Knuckles was breathing fairly hard and shaking, having denied himself another orgasm. But this time he didn't have a single ounce of detectable rage, his tense body soon went limp yet his dick still ached. 

"Hmmm interesting... What's weighing on your mind, guardian? Perplexed how the sight and scent of my cock makes you crave a good fucking in both ends?" Finitevus asked cruelly and Scourge's boner bounced back from the lewd talk.

Knuckles groaned and trembled as those thoughts played out in his head, sending a surge of hot lust throughout his entire form again. The red echidna twisted and turned in his bonds much to the delight of his two tormentors. "Hnngh, ahhhnng, Ho-how long" The guardian stammered out.

"Hmm? What's that?" The doctor asked, idly playing with his own cock underneath his cape again, keeping himself hard for the main event that was building up. "Do you have a question, Guardian? Please do inquire away, as I'm a scholar and it's my job to inform"

Thank chaos Finitevus was so long-winded. It gave Knuckles time to breathe and get his thoughts back from the abyss of lust that kept drowning them out. "How... How long will this... formula last?"

This was something Scourge himself wondered ever since the doctor yelled at him for overdosing the echidna. Seeing the effects take shape and how powerful they were firsthand only made him more curious about it. He looked to the doctor to hear the answer.

"No pussyfooting around, I estimate the formula will still be strongly coursing through your system three days from now" The white echidna answered, and in doing so figured out another advantage. "But... I have an antidote right here" 

Knuckles felt doomed at the answer of three days or more, it was gut retching to imagine being in such a needy state for so long. But his head lifted when Finitevus mentioned an antidote, some hope feeling restored as he saw the doctor remove an orange pill vial from his cloak. "An-antidote? Ah, give me that! I don't want to be like this any longer, have some decency for once and jus- just end thi- Ah, aahhhh~"

Finitevus pulled Scourge in front of Knuckles and pushed the echidna's head down to be level with his throbbing stiff meat. He was silenced again by the thick scent overriding his rational mind. But the doctor quickly pushed the hedgehog away, just wanting his captive to get a quick mind numbing whiff. 

Scourge grumbled. He hated being pushed and shoved around, but he was putting up with it and being patient for the doc's sake and the promise of getting his rocks off.

The white echidna started talking again when he saw the guardian was  failing to keep his bravado. "You don't get to tell me to give you the antidote, Knuckles. You're going to agree to this deal because it's your only choice." Enough with the tests and concerns, it was really time to drop the hammer and get things started. He smirked evilly and stroked Knuckles' chin. "You're going to let us fuck you, and then you'll get the antidote"

He knew soon after this started that that would be the endgame Finitevus and Scourge set out to fulfill. However, knowing it certainly didn't bring any kind of comfort to Knuckles. He started to blame himself for being caught in such a way in the first place. What was the point in being angry now anyway when it was all his fault for not being careful enough? He knew he was lucky they didn't just outright poison his food.  "I hate you...both...so much"

"I take pleasure knowing that you do" Finitevus mused. "But that's not an answer, guardian" He gave a smirk and tapped the red echidna's nose.

Knuckles muttered disdainfully and his nose twitched. "I don't want to agree to your terms..."

"You don't have to want to, Knuckles. But do you really want to be desperately horny and unable to stop touching yourself for a possible week or longer? My I can only imagine what your friends would think if they find you up here, exhausted and covered in your own semen"

"Uurrgh.... Damn you..." Knuckles bared and grit his teeth. He was once again trying with all his might to pull free from the floating rings, tugging and yanking as hard as he could to get free. Veins bulged in his forehead as he struggled with all his might. The damn things wouldn't budge and Scourge was laughing as the echidna only managed to make his feet sink into the ground. "ARRRRRGGGHHHHHHHHH!!!!! ...FINE!"

The doctor and criminal hedgehog watched the frustrated echidna give up and start panting, his face red from straining so hard against his bonds. "Fine, what?" The scientist asked with a knowing smirk. 

"Do it..." Knuckles had his eyes closed. He could feel the brooding heat of arousal beneath the surface already creeping up to claim him like a tidal wave. Just the process of giving in and knowing what was to happen when he did, amplified the lustful feelings and urges. "Just do it and get it over with!" 

"That's a good boy" Finitevus hummed, seeing Knuckles already succumbing to his formula. "We're still going to put this on you just in case" He held up the ring gag to the red teen's face and smirked to witness him whimper and reluctantly open his mouth for it to be fitted inside.

"Oh man, this is fuckin' hot" Scourge muttered to himself under his breath as he viewed the scene with great interest, Finitevus reaching around behind a blushing Knuckles' head to buckle the sex device tightly in place.

"Now down on hands and knees" Finitevus said with a glee that made Knuckles shiver and want to back out, if only he could. But he knew he could only brave what was coming and try to fight from slipping into that actually frightening endless pit of lust.  His heart was racing again as he was lowered into position by the doctor, placed down on all fours. He held his breath to avoid the mind numbing scent of arousal when the white echidna's tented cape bopped him in the cheek. He told himself he could get through this, then he would be back to normal in no time. If he could take a beating, he gulped and thought to himself, he could then take a fucking.

Knuckles next felt the older male's hands on his body, positioning him the way he pleased. "And arch your back here~" He trembled under those hands on his back, gracing his over sensitized nerves with an aura of pleasure. 

"Hnnn, nnnngg" He moaned out, wishing he could bite his lip to stifle the noise. It was strange though, how the ring keeping his mouth wide open wasn't as uncomfortable as he thought it would be. Perhaps it was because he was focusing harder on not becoming a pleasure puppet to these two psychos.

"Oh fuck, that noise~" That moan was just too hot.  Scourge got into position in front of Knuckles and pointed his large cock at the metal ring, pausing to savor the sight for a few seconds.  "Been waitin' to feel your muzzle around me all day, Knucklehead~" 

Knuckles groaned at Scourge putting emphasis on that nickname. It's all he could manage in protest before his eyes went hazy, lust flooding his senses as that thick mushroom-head of Scourge's dick passed the ring. The heat of it greeted his tongue and compressed it with it's firm presence, the girth throbbing  and slowly starting to slide back and forth. "Mmmnn, nnggghhhh"   He moaned around it, trying to sound displeased about it.

It was hard to sound displeased though when he was really more turned on now than ever. He was fighting a losing battle in trying to keep himself from slipping. The taste and feel of Scourge's cock glided along his tongue, intoxicating him with a sturdy discharge of pre-cum that was overpowering. Soon he found himself sucking and moving his head without much of a thought, like he was in autopilot mode, even working his tongue against that hot pulsing shaft filling his maw.

"Mmmm, damn~" Scourge purred and placed both hands on Knuckles' head, not forcing him or moving his hips. "He's givin' me a lazy BJ" The green hedgehog snickered and allowed the red echidna to continue sucking him at his own pace. He may have been going slow, but Knuckles was using quite an intense amount of suction that felt amazing around his dick.

"I've always found it fascinating, guardian." The white echidna finally spoke again as he moved around behind Knuckles, favoring the view of him sucking dick from behind. "You may be a small compact package, but a true force to be reckoned with despite it." 

Knuckles was feeling strange, like he was on happy gas at the dentist. It was hard to make sense of things, but he kept going through the motions for the amazing feeling it wrought upon him. His cock pulsed and throbbed on edge as he sucked and slurped on Scourge's, starting to take it deeper and quicker. His long locks moved back and forth, tapping the hedgehog's legs from the inertia. 

"Heh, he actually looks like a girl from my angle" Scourge blurted out to Finitevus, aiming to ramp up the humiliation of the guardian. "Sucks as good as one, and his long hair's even tickling my knees"

Knuckles could make out the words being spoken but they instilled no kind of significant feeling. There was a fleeting thought of shame but it didn't stop him from moaning and bobbing his head along the hedgehog's thick cock. There was a clear feeling of humiliation, yet he kept sucking on him with no indication of hating it.

"He looks quite like a girl from back here too" Finitevus chuckled, getting down on his knees behind Knuckles. His cock was still tenting his cape and was getting more eager as he place both hands on that cherry red ass and groped those soft round cheeks. He gave them a nice rubbing and firm groping, causing Knuckles to make a whine up front while his back end fidgeted. "He has a decent curve to his lithe frame" Finitevus chuckled, savoring the feel of the teen guardian's rump in his hands. "Always intrigued me how he doesn't look like much in the way of toughness, lacking any kind of macho stature yet can decimate boulders with one blow. But I guess that's one thing that fascinates me so much about the chaos energy in his DNA"

Knowing  the red echidna's strength and seeing him on his hands and knees with his mouth full of cock served to fuel the white one's sex drive further. Soon  the doctor removed a beaker of blue liquid gel from his cape and started applying it to two of his fingers . "Yes, if he wore a skirt and makeup I've no doubts he could pass as the opposite sex" He smiled while thoroughly coating his fingers.  "In any case, he'll probably cum like a girl in a few seconds as well" Finitevus said, wearing a devious grin while touching his lubed digits to the younger echidna's tail hole.

Knuckles' tail twitched, he made a surprised noise and stopped his movements on Scourge's dick when something cold and slick was felt under his tail, prodding and sliding around his pink ring. It brought a shiver to coarse through him so hard he fidgeted and made what sounded like a whine as the doctor pushed one slick finger in past his resistance, sliding it in deep up to the knuckle. "AHhnh!" He gasped, the hedgehog allowing him to do so as he pulled his dick free of his hot wet cavern. 

"I don't wanna cum just yet. I'll let ya focus on what the doc has in store for ya now" Scourge laughed and pat the guardian's head, before making him wince by slapping his saliva coated cock against his face. 

He wanted to blow up like an atom bomb and destroy these two. But that was a thought deep down that Knuckles couldn't grasp with the intensity surging through his rear end, stemming from Finitevus slowly circling his finger inside of him. His head bowed and his soft panting grew into pitifully restrained moans. His hole reflexively squeezed around the mad one's digit and that added more pleasure than he could take. "Hnnnn, ahh, nngg-nnnnnnngghh!" His being was wracked with devastating waves. Finitevus wasn't even moving his finger, yet Knuckles was shoved over the cliff of the most intense orgasms he ever felt! "Ahhh AHhh, NNNGGGGG!" His cock swelled and fired off thick rocket like streams of his seed into the grass below.

Finitevus was pleased with the result, his own dick twitching with eager beneath his cape as he enjoyed the sensation of Knuckles' hot virgin ass clamping around his finger. More so he was loving how the guardian started to slowly ride out his climax, unable to help himself but to move back and forth along his buried digit. "That's it, give in and enjoy yourself dear guardian~"

"Hahhn, ehhhnh" Knuckles was lost in the moment, swallowed up by the sensations of the ever growing sexual advances. Scourge took delight in rubbing his dick all over his face, finding pleasant surprise when the crimson male began to nuzzle and push his own face into it. Why couldn't he stop himself? The question didn't stick to the forefront of his mind long enough before he felt a second finger prodding  at his hole, then arched his back as he felt his ring stretching more to allow it inside with the first. 

"Mmmm yes, you're so tight back here, Knuckles~" The twisted scientist mused whilst using his left hand to spread the guardian's cheek, gifting himself a nice view of his slick fingers moving in and out of the other echidna. 

"I think you're ready for another taste of my dick meat" Scourge announced and Knuckles gave no protest but a simple whine as his half lidded eyes watched the hedgehog's girthy member approach his muzzle.  This time his tongue moved to greet the head, licking off the nice bead of pre-cum that oozed from the slit. "MMmf, damn. Y'like it now huh?" The hedgehog smirked and took hold of the echidna's locks, slowly pushing his length deep into Knuckles' forced open muzzle.

Knuckles had no protest, but a lowly groan in his throat as he tasted the warm slick and sweet liquid, his taste buds basking in the precursor cock juice. He quivered as Scourge's cock filled his mouth again, but was being pushed in further. At the same time he moaned as he felt Finitevus' two fingers slowly twist and move back and forth beneath his twitching tail. His cock was still hard despite just cumming, a deep intense pleasure still feeling present in his loins as the doctor gradually quickened his finger fucking. 

"Mmm, what lovely results" Finitevus smiled and pat Knuckles on the ass with his free hand. "Now let's see how he reacts when I actually touch his prostate" Being a doctor, he of course knew right where it was located too. But he didn't go in on full assault against it. Instead he gently curled his fingers inside Knuckles and teasingly nudged his finger tips against the target.

Knuckles swallowed as Scourge's dick reached further into his throat. He was moaning and letting the green hedgehog do what he pleased when Finitevus found that spot inside him, making him absolutely quake with and immense rush of amazing bliss. He was blacked out now, cumming on the ground again while he started to go wild on Scourge's hot bulging tool. "Mmmnngh, mmmm~"

"Oh~ Ooohhf fuck yeah, Red~" Scourge was loving the way Knuckles sucked his dick, pulling the skin up and down as per proper way to milk a male. "Ahh, damn he's really goin' for it now. Heh... lemme help ya out~" The scarred and leather clad hedgehog huffed and tugged the guardian's hair as he started to move his hips back and forth, fucking Knuckles' hot mouth. 

Finitevus was all too happy with himself for triggering the young guardian's second climax. "Mmm, just from a few gentle rubs and you're still cumming" The doctor announced, slowly withdrawing his fingers from his captive's slick hole. "Your entrance squeezes nicely during your climax, Knuckles..." He parted his cape and pushed the fabric over his shoulders before getting in position to mount him. "I must know how good your ass feels around me when you cum from a proper fucking~ Oh yes, you feel the head of my cock on your hole, guardian? You're so slick and ready to breed"

Knuckles could hardly care anymore at the current time, his thoughts were distant and everything was hazy except for the strong scent and taste of male arousal. Scourge's sack pressed up against his chin and his big dick was shoved deep in his throat where he could feel it pulse between his tonsils. Meanwhile he felt a pressure push against his back door, steadily intensifying until he felt himself spread little by little. He knew Finitevus was slowly working his cock in past his tight ring and groaned as the head of the doctor finally slipped in through the resistance. 

"Ooohhh yes~" The mad one gripped Knuckles by the hips, shivering delightedly as he continued to push himself forward, watching with great satisfaction as his pulsing cock disappeared into the guardian's ass inch by inch. "Such a hot... tight little tunnel~"

Scourge was beginning to pant and huff, nearing the verge of his release as he fucked the red echidna's drooling hot muzzle. However, the hedgehog still didn't want to cum yet and pulled his member free before slapping Knuckles across the face. Not hard, only to induce a short moment of clarity.

In that moment of clarity Knuckles felt the base of Finitevus' crotch bump against his hind cheeks, the doctor's cock now sheathed deep to the hilt inside his ass. Oh so full he felt, his hole tight around the long girth of his enemy's throbbing dick. He saw Scourge's rod of hot flesh standing before his nose, twitching and covered in his saliva, letting him know what he'd been gleefully sucking on. As he stared at it he could still taste it on his tongue, yet his mouth felt empty and the flavor was dissipating. ...He wanted more of it.

"Ooohh, aahhh this is better than I'd imagined, guardian" Finitevus held Knuckles' tail in a fist grip near the base, tugging the appendage upward to better see as he moved his hips back and forth slowly. "Your hot depths are almost pulling me in~

He was thrown back into that blinding mist, moans bursting from him and his toes curling in his shoes as he was fucked slowly by the doctor. Knuckles knew it shouldn't feel this good but his body betrayed him again, his head tilting up with a ragged gasp as he hit yet another climax already.

"AHhhhnnnhh Aahhh- ahhhhhnngg~!" Knuckles shuddered and basically lost his breath as his orgasm gushed from his impossibly sensitive cock, shock rolling through him as he erupted a heavy spurt of cum every time Finitevus thrust forward into his prostate. 

Scourge was beyond turned on at such a look on Knuckles' face, the epitome of lust drunk needy slut. "Yeah, you like getting drilled front ways and back by two dicks don't you?" He mocked him and held his dripping tool by the base so that he could use his tip to wipe his pre-cum everywhere he could on Knuckles' face.

Finitevus shifted his stances and started to move his hips faster, now creating soft slapping sounds as his pelvis met with the guardian's superb rump. He had to grunt as that hole was contracting around him every other second still, the red one's orgasm run dry but still giving the sensations of climax.

At least by now Knuckles got used to it enough to finally take in a deep breath of much needed air. Then he went on to start panting and gyrating, not able to stop himself from pushing back against the doctor's quickening thrusts. His tail hole felt like it was burning up, but with a most enjoyable friction that radiated heat throughout his ass and tingled his balls. But his mouth was tasting rather bland and getting dry. He looked up at Scourge with a needy expression.

The hedgehog grinned and stroked his cock, gladly moving back into position to slide himself into the guardian's moist cave. "Yeah, round three begins now... I hope you're lookin' forward to the finale, slut~ Heh, try not to choke" He grabbed bot sides of his head and commenced to fucking his mouth, ramming his girth into the crimson one's throat where he was forced to swallow around him.

Finitevus kept building speed, encouraged by how amazing the young guardian's inner velvety wall felt hugging onto his large dick. His  hips bucked into Knuckles' rear hard enough to start bumping him forward into the hedgehog, giving him a proper spit-roasting. The doctor's loaded sack slapped against the guardian's taint, the older echidna diving his cock balls deep into him every time he thrust forward. Knuckles felt the hands on his hips tighten, his hole getting warmer from the continuing friction of the dick plowing in and out of him getting faster and rougher.

He came again, but was almost numb to it by now. The pleasure crashed over his body and his neglected tool pulsed below, causing him to moan and suck on Scourge with more eager and more effort while his tail hole clung onto the doctor fucking him from behind.  

"Woah... Ooohh fuck, man~" Scourge's face twitched as Knuckles sucked on him like it would save his life, his slippery hot tongue swirling around and rubbing against every sensitive inch. It was as if he was aiming to make him cum, and without a doubt he was leaking a fair amount of pre-cum which Knuckles seemed to enjoy. "Nnnghh, damn, alright ah fuck I'm close" The hedgehog informed, swelling up in the guardian's maw.

Knuckles watched as that cock exited from his propped open muzzle, strands of pre cum and his saliva stretched out between the hedgehog's impressive member and his lips. Still he panted and made a number of interesting noises while Finitevus was now ramming into his ass with rough and rapid vigor.

The white echidna grabbed both of the red one's wrists trapped in the rings and pulled his arms back, grunting and growling as he bucked harshly into him. Meanwhile up front, Scourge stroked his dick and kept himself on edge. The hedgehog soon tilted Knuckles head up by his chin and looked into his lust laden amethyst eyes while he pointed his leaking member downward above his gaping mouth. "Mmmff, gonna bust~" He grit his teeth and grunted from the powerful climax surging and pulsing through his dick, firing his hot pearly white seed directly through that ring gag.

 Shot after shot of cum spurted into Knuckles' mouth where it accumulated at the back of his throat before he was forced to swallow, a display that really got Scourge hot and influenced a greater orgasm. "Oh yeah, love seein' my jizz disappear down your gullet, Red~" He had to dip his dick mid climax back into the guardian's hot maw.

Knuckles groaned at a complete loss, his mind gone and replaced with the craving for sex. All he could focus on was how good Finitevus's cock felt, harshly driving in and out of his tail hole, quicker, harder and deeper. He also couldn't ignore his mouth filled with warm cum and a hot twitching cock tapering off it's climax to a dribble on his tongue. The taste was so potent and thick, salty, creamy and musky. He swallowed and could feel it slide down his throat in voluminous globs.   

"Good job~" Scourge rubbed Knuckles' head roughly and removed his spent dick from his muzzle. It had a nice bit of seed on it so he rubbed it off on the red echidna's face. With the blow job done, the captive guardian let his head fall and started to breath heavily. Another orgasm struck, completely wrecking him as Finitevus fucked him so hard he forced a few watery spurts of semen to drip down his cock.

"Nnggg, now it's my turn!" The doctor suddenly shoved Knuckles onto his stomach and came down on top of his back, never pulling out of his hot red ass. Knuckles writhed and moaned, drooling with the side of his face in the grass. He was continuing to cum, more intensely from his hard on rubbing into the soft blades of the grassy ground beneath him. His ass squeezed and contracted around Finitevus from his climax, and it only served to milk the white echidna past his limit.

"Ooohh, oohhh yeees, guardian aahh ooohh~" Finitevus took his orgasm slow, making Knuckles feel him gyrate his hips as his crotch was flush with his red cheeks. He elicited a whine from stirring his pulsating dick around, deep in Knuckles' ass while he unleashed the contents of his balls into him. "How's it feel, Knuckles? Hot cum of your hated enemy, nnnf, filling up your ass~"

It felt warm, incredibly warm and amazing to Knuckles in his current state. He panted and huffed, moaning in blissful fashion. Finitevus' cock was throbbing away in his stretched hole, his seed flooding him up to the brim until a trickle leaked out. What more, he gyrated his own hips, having given in to the formula completely by this point.

Scourge was off to the side, sitting on a boulder and smoking a cigarette as he watched the doctor finish up with Knuckles. That drug truly did look like it made quite an impact on the usually vicious and threatening pipsqueak, the way he now looked like some kind of begging slut puppy for dick. It was really amusing actually.

Finitevus gave a few hard jerks into Knuckles, then pumped his hips up into him a gentle series of times to milk out every drop he had to offer the virgin guardian's ass. "Mmmmmyeah, that was exquisite~" The doctor shivered and took a firm grip on both luscious cherry cheeks, spreading them apart for a lewd look at his cock as he withdrew from Knuckles' twitching hole. "What a beautiful sight~" He commented on the brief stream of seed that rushed out of his tail hole and flowed down his taint and over his spent balls. "There's much more I'm sure will be stuck in there for a time"

After that Knuckles winced from a slap on his ass, then heard Finitevus get up to walk away. Panic set in suddenly and he was about to make noise in protest. But a pill vial was tossed onto the ground in front of his face and Finitevus was heard, prompting him to look over his shoulder at the older echidna with a glare.

"Now that look you're giving me is exactly the reason why I decided not to unbind you..." The doctor said, reading his young enemy's fears. "But don't worry your pretty little head, guardian. I'm going to deactivate those magic rings the moment I'm back in my lab. Two pills should return your sex drive to normal" He then gestured Scourge to his side as he opened a warp ring, but sneered at the hedgehog and slapped the cigarette out of his hand.

Knuckles huffed and growled, seeing the two leave without much of a care.  He wouldn't put it past Finitevus to hold off on deactivating the rings, and after two full minutes he was preparing to be stuck there a while. It was a situation that wouldn't be so worrying if that lust formula wasn't starting to take effect again. However, just as he was fighting the urge to hump the ground, the rings around his wrists glowed before expanding for him him to pull his hands free.

Quickly after that he sat up and reached behind his head, frantically unbuckling the ring gag as fast as he could and pulling it out from his teeth. "Ah! Haaah finally!" Oh it felt amazing to move his stiffened jaw once again after it was held pried open for so long. Not too much time was spent flexing his mouth though, just until it was comfortable enough. What was most important was curing himself of the horny disease. 

He stood up and started to walk towards the vial Finitevus left. Each step he took brought a brief flare up of that formula's effects, the slick and slippery sensation of warm cum between his cheeks reminding him of the fucking he recently endured. The thought of it made his cock hard again and he had a taunting urge to reach under his tail himself.  Man, that stuff was strong. "Sh-shit aahh, gotta take it now!" Knuckles yelled and dove for the bottle, hastily uncapping it and gathering two pills which he tossed in his mouth to swallow without a drop of water.

Now he would lie there, panting and fighting off the arousal until the antidote did it's job. At least, he hoped it would work. But in the meantime, he needed to listen out for anyone that might come by. Chaos knows Sonic usually showed up at the worst times. Knuckles wouldn't have a clue how to explain the state he's in now if that happened.

Or he could threaten him... That usually worked.
