Knuckles the echidna and Silver the hedgehog both approached Tails' workshop. They'd seen the explosion that had gone off in the area some time ago, and concerned as they were, they weren't dim enough to try running in without any information.
They both tried to gather information on the situation, but no one was quite sure where where Sonic, Tails, or Shadow were. All were presumably caught up in some kind of trouble, a theory that was only reinforced when both Silver and Knuckles picked up on a distress signal coming from Tails' workshop.
It was in route to Tails' that Silver and Knuckles met up with each other, heading in together. Strength in numbers and all that. They approached the building, shocked that it was somehow standing despite the radius of the explosion.
They were both on guard, and as such nearly attacked when they saw Sonic leaving the building. When they recognized who it was, the two of them rushed forward to him to see if he was okay.
The two were quite shocked when Sonic went from weak stumbling to near his top speed in less than a second, striking both of them was several directions. The two took basically an entire battle's worth of beatings in point four of a second.
They dropped to the ground, Shadow stepping out and using chaos control, teleporting both of them into the basement, where Tails was waiting for them. They looked up in confusion at Tails, unsure what in the hell was happening.
Little as he understood, it didn't take much for Knuckles to know Tails was the current threat. The mad grin on his face spoke well enough to that. Couple that with Sonic attacking him, and Knuckles presumed there was some sort of mind control at work.
This in mind, Knuckled kicked off the ground, throwing a powerful blow at Tails. His logic being that he could perhaps throttle the mind control out of him.
Tails caught Knuckles' punch easily, seeming to exert no force whatsoever. He gave a grin, driving his fist into Knuckles' gut so hard it lifted the echidna off the ground. He landed hard on his back, gasping for breath before his head was grabbed.
Tails didn't even wait for Knuckles to be breathing properly again before slamming his stiff length into his throat, completely filling it within seconds.
He gagged hard, unable to breathe and panicking now that his strength had done nothing. He went for the most obvious way out, biting down hard on the member in his mouth, but Tails' new strength made that impossible, not doing any damage or bringing any pain.
If anything it just hurt Knuckles to try, like he'd tried to bite into solid steel. Tails grunted, forcing his head down harder as he thrust his hips down as well, forcing more of his cock in to drill the echidna's throat. Silver knew he needed to escape, but he wasn't sure how now.
Tails was radiating more power than he could even properly measure, and even if he could think of a way to sneak passed him, Sonic and Shadow stood nearby like well trained attack dogs. Silver gulped nervously as he watched Tails use Knuckles' throat like a toy, his balls slapping against the echidna's chin as he drilled his throat. His tails moved down, holding Knuckles' arms and legs so he couldn't struggle.
This let him use his hands to keep a tight hold on Knuckles' head. He moaned out happily as he fucked Knuckles' face mercilessly, able to feel how close he was to passing out. He grit his teeth, the knowledge that he was literally fucking the powerful echidna into unconsciousness bringing him over the edge.
Knuckles gagged harder as his throat was flooded, unable to breathe still as he was forced to swallow it all down.
Tails slid out of Knuckles' throat, letting the unconscious prey fall to the flood. He chuckled, turning Knuckles over and slapping his nice, juicy ass. He licked his lips upon seeing how it jiggled from the strike. Tails lifted Knuckles' up, his tails holding Knuckles' legs apart, his hands holding his arms apart.
He lined himself up to Knuckles plump cheeks, sending a jolt of energy through Knuckles body at the last moment to wake him back up. Knuckles couldn't even recall where he was or what was happening before he was pulled down hard, feeling a monster sized cock force his tight ring to spread open hard.
Knuckles screamed out in pain as Tails' tree trunk of a cock stretched his asshole, his hips beginning to move to pump into him aggressively. Sonic and Shadow watched from nearby, Silver thinking now might be his chance.
As he started to move, he paused a moment when he noticed something odd. Both Sonic and Shadow had what looked like Shadow's inhibitor rings, but locked around the base of their cocks.
Presumably they functioned like C-rings, keeping them both rock hard and also preventing them from cumming no matter how badly they needed it.
Silver mused on whether Tails had forced those on and used them to make the two of them work for him, or if they'd willingly allowed them to be put on after being controlled.
Either way, it was Silver's inquisitive nature that foiled his own escape attempts. Whether or not he'd have been able to escape the sex dungeon in the brief moment all eyes had been away from him or not would never be known, because the moment had passed now.
Shadow looked back to Silver, seeing the platinum hedgehog poised to bolt for the door. He rose a leg and striked Silver in the jaw with a kick. He was forced back against the wall, Sonic delivering another solid kick to his stomach to keep him down as Tails continued to play with Knuckles.
Knuckles' wailing hadn't quieted at all, Tails having gone from a rough pace to an even rougher pace as Tails sawed into him hard, utterly ruining his asshole. Tails switched to holding Knuckles up with one hand. With his free hand, he reached around to Knuckles' crotch.
Knuckles' cock had naturally grown hard from the stimulation, letting Tails grip him and start begin stroking him hard. Knuckles' cock was quite sizeable Tails realized; thick and solid.
It would be quite impressive, were it not for the size of Tails' member within view. He squirmed hard from the jerking, only causing his already tight gripping anus to squeeze even tighter around Tails' cock.
Knuckles squirmed around Tails' cock, his movements only helping his ass milk his new master's cock more. Tails chuckled at this, letting Knuckles writhe on his cock as he jerked him harder, sending small rushes of energy through his hand and into Knuckles' cock as her stroked him. Knuckles yelped as he felt it, plain and pleasure rushing through together, like he was having electricity flow through him but several times amplified.
His body tensed even further, Tails grunting as he put more of his strength into each thrust, trying to ram his entire length into the echidna. His tongue began to lull out of his head as he felt Tails slamming up into him, feeling like his entire body was being drilled. Tails could tell Knuckles' mind and body were both getting weak, but didn't stop.
He didn't stop when Knuckles came, coating his hand in warm seed, nor even when he came into Knuckles, flooding him hard with thick release. He kept going into Knuckles, pounding him harder after each release, letting more energy flow through his rod as he stroked him, forcing stronger and stronger orgasms out of him.
Tails didn't bother keeping track of how much time he nailed the emerald guardian, nor how many times they changed position.
Rather, he kept going until Knuckles' cock physically couldn't release anymore; his body slumped, conscious but not aware, member too worn out to even remain stiff. Tails, having only cum three times up to that point, let Knuckles fall off of his member. He landed in a large puddle of his own cum, ass full several times over with Tails' seed.
Tails stroked himself over Knuckles, finishing the job and painting the back half of him with his cum. This done, Tails turned his attention to Silver. A shiver went up the psychic hedgehog's spine, as he'd now seen more of Tails' incredible power.
Tails gave a smile, looking to Shadow and Sonic, "You two, have a little fun with Knuckles. Do a good job and I might let you take the rings off for a bit~" He purred, Sonic and Shadow bolting in a full tilt sprint to the prone echidna.
As Tails moved to Silver, Shadow and Sonic moved Knuckles into a vaguely doggy-style position, having to keep him up themselves. The two didn't hesitate to thrust into him from either end, spit-roasting him without shame.
All they could think of now were following their master's orders and earning some release if they were good. Knuckles was too out of it to even really take note as Shadow and Sonic plowed into him, his ass numb to the point that he could barely feel it anyway.
Silver, refusing to go down without a fight, fired off several psionic waves at Tails, putting as much power as possible into each attack.
They flowed over Tails with enough force to rend entire sections of a city, though they felt little more than summer breezes to Tails at this point, his body not seeming affected at all.
Despite the lack of effect, he decided that Silver needed a proper punishment regardless. He held out his hand, focusing the chaos energy flowing through it into the palm and creating another of the golden rings that Silver had seen on Sonic and Shadow.
Silver was on his guard, sure that Tails would intent to lock one onto his own member. Silver was fairly confident in his own mind and body, but then again, Knuckles probably had been as well and now he was being more broken every moment.
If there had been any hope of a grand battle, it was over before it started, Tails grabbing Silver from behind before he even realized that Tails had moved. His tails wrapped around Silver's hands, holding them out so he couldn't properly struggle with his psychokinesis.
He lifted Silver off the ground and slammed him down hard onto his cock, Silver wailing in pain as Tails moaned in delight, "Such a nice, tight girl~"
Critical as the situation was, Silver couldn't help but blush at this comment, face burning red. Tails groaned in pleasure as he bounced Silver hard on his rod, moving his hands around him to stroke his rod just as he'd done with Knuckles. Unlike with Knuckles though, he didn't let him cum.
He stroked his rod to full hardness, continuing to jerk his solid cock as his buried more of his own inside of him.
But when he felt Silver's cock throbbing, about to cum, he let the ring he'd created slide down the length of Silver's cock.
Once it reached the base, it squeezed tighter and locked into place. It was more chaos energy than physical, and completely blocked off Silver's ability to cum no matter how much pressure built up.
"Good girls don't cum without asking first~" Tails purred into Silver's ear, "Ask for it nicely, say you're mine, and then you can cum all you like~" Silver grit his teeth, closing his eyes and trying to focus his mind.
Maybe, he thought, if he built up enough mental power, he could blast Tails off of him and escape, get reinforcements and undo whatever had been done here. All he had to do was stay focused, block out the physical realm stimulation become zen.
He'd done it before in trying situations against impossible odds, he could do it here.
But as Silver would soon grow to understand, he'd never done so against a being on Tails' level of power. Tails continued to drill into Silver, pinning his body against the hard floor as he thrust more deliberately, pulling his entire cock out of him and thrusting his entire length back in with every movement of his hips, growing faster and stronger every few thrusts.
Silver's tension grew, body tense and sweating as Tails abused his body, all the while whispering to him how pretty and wonderful feeling a girl he was.
He tried to focus, really he did, but he was only capable of so much. He'd managed to built up energy sure, but if anything that made it even harder to focus the longer he went, as there was pressure building up psychically as well as physically.
His body felt like every square inch was being pressed down on, like a black hole had appeared at the core of his body and he was being pulled into himself.
His member swelled more and more, twitching and throbbing for release, but receiving none. Silver lost track of how long he'd been beneath Tails. He knew he'd been turned over twice, Tails fucking him with his legs down to the floor and up in the air, pulling out and cumming hard onto his fur both times.
He was changing position again now, turning Silver onto his side with a leg up over his shoulder, treating his poor prostate like an advanced stress toy. From here, Silver could see Knuckles sandwiched between Shadow and Sonic, both of them pumping their own cocks into his asshole together.
Seeing this suddenly caused a whole new wave of panic to flow through Silver as he realized that they'd both been fucking Knuckles as long as Tails had been fucking him with the ring on.
There was no telling how long they'd been locked into the rings before they had arrived today (assuming they'd only been there a day, Tails didn't seem to have any upper limit to his energy and likely would show no change if he'd been at it a year in).
Silver already felt like his whole body was ready to break down, and if Tails could just keep on going ceaselessly, not stopping until Silver's entire body shut down… the phrase about blood turning cold came to mind, but he'd been rutted far too hard for far too long for it to be literally accurate.
In any event, he opened his mouth, timidly whimpering, "I-I-I give…" He said, unsure what else he was meant to say.
Snickering, Tails rammed his cock against Silver's prostate again, "If you want to cum, just say, 'I'm your girl master, can I please cum for being a good girl?' and promise to submit forever~" Silver bit his tongue to nearly the point of bleeding, trying to force himself to stop. To his credit, he managed to hold out a few minutes longer.
During this time, Tails told Shadow and Sonic that they'd done an excellent job. With a snap of his fingers, the rings he'd locked onto both of them faded away.
As they came for the first time in who even knew how long, they let out cries of relief so intense it send a shudder through Silver, who's body was desperate on a primal level for the same satisfaction.
Sonic and Shadow more or less collapsed from the pleasure, though Tails refilled them with energy with naught but another snap, preventing them from fainting. At his order, Shadow moved over to Silver, wrapping his lips around his cock. After a few more moments, nor his body or mind were strong enough to hold out any longer.
"I-I'm your girl.." Silver said, "P-please.. I promise, I-I promise I'm yours forever, I'm yours, m-may I please c-cum for being a good girl?" He questioned.
Grinning, Tails rammed one last time into his ass, unloading this thickest, hottest orgasm of the day into Silver as he allowed the ring to vanish from his cock. Silver practically screamed as he dumped his release into Shadow's throat, his entire body writhing from the satisfaction, mind cracking apart from it.
Tails slid out of Silver's asshole, giving Knuckles and Silver the same energy recharge as Sonic and Shadow, so despite their fractured minds they could still stand at attention. He sat down nearby, still solid cock standing at attention.
On Tails' order, all four of them crawled over, beginning to kiss, lick, and suck along his shaft and his balls, all of them submissively following his orders without question.
Tails smiled in satisfaction as he looked over the four of the them. He had all the males he wanted. Now, he thought, it was time to move on the girls~
