With a pulsing migraine and strange weakness, Shadow's eyes gradually cracked open, viewing a reinforced concrete ceiling from which a single dim light hung above him. His throat ached, but as he tried to reach up to rub it, he discovered the resistance holding down his arms was too great. 

*What happened?* he thought to himself, trying to recollect the events prior to what made him lose consciousness. It didn't take long for him to recall Infinite being involved before a flushed feeling overcame his entire body. His fur began to stand on end as he felt a hot, wet force enveloping his member.

Peering down, he saw blue quills dancing forward and backward in rythmn with muffled moans escaping below. As his eyes adapted, he saw to his bewilderment Sonic suckling and slurping his cock, taking great pleasure in each stride over its stem. His wounds were still visible as the jackal elected against treating him so that Shadow could witness his suffering. Although his body's overall movements weren't steady, he asserted all his efforts to staying upright and maintaining alignment.

"S--Sonic...what are y-you doing?" Shadow grunted, the haziness slowly lifting while his senses were bathed in the warmth of ecstasy. 

The blue hedgehog didn't respond. His attention was solely on the task at hand, or rather, in mouth. He pressed his lips firmly around the shaft as he pushed his face as close to Shadow's lower abdomen as possible, allowing the tip to sink down his throat. Then, with just as much ferver, he backed away, swabbing his tongue across it while doing so. 

The sensation sent chills through the black hedgehog. When he tried to move his arms again, he discovered them bound by thick barbed wire that was looped numerous times to the back of a metal chair, piercing and carving his flesh. He tried to move his legs, but found them in the same predictament. He felt his member hardening by the minute, tingling, pulsing, making it impossible to concentrate on anything else. He began to breathe heavily, sweat forming under his fur as the stimulation intensified. Though he could feel Sonic's hands shaking on his thighs, he was like a machine! Relentlessly keeping the pace with almost no breaths in-between. Try as he might, there was no stopping him! 

Shadow's back instinctively arched as he began to reach the pinnacle of the moment, no longer able to resist the tantilizing sensations his partner was inducing. The barbed wire dug into his skin, keeping most of his movements at bay. While climbing to the highest level of pleasure, a voice broke through the darkness.

"--That's Enough--"

Like flipping a switch, Sonic immediately stopped and removed Shadow's equipment from his mouth, the member dripping and twitching from the excitement, only to be left in the cold without finishing the needed release. He then looked up at his partner and smiled weakly, his eyes glistening with barely visible pupils as secretions dripped from the bloodstained sides of his lips. Behind him, the foreboding jackal emerged from the dark.

"You seemed to be enjoying that--" he chuckled.
He then handed the broken hero a small metallic pin, coated with some sort of substance that shimmered in the pale light. 

"Insert It--" he commanded. 

"Oki dokey!" Sonic replied, accepting the instrument with one hand while forming the "okay" gesture with the other.
Obeying his master without hesitation, he grabbed the Ultimate Life Form's swollen member once again, concentrated on the target, and slid the rod through the tip of his urethra. 

"NNNN----AAAAHHHHHH!!!! S-STOP!!! ---SONIC!!!" Shadow screamed as the blue hedgehog hummed to himself while pressing the pin deeper and deeper without delay until it couldn't go any further. 

The pain was indescribeable! It felt like a dozen bees were stinging his insides! Every muscle in his body tensed, creating more injuries from his restraints. He could feel his heart pounding in his chest like a drum. The small sweat that had initially appeared from pleasure now compounded on his fur while he tried vigilantly not to move, hoping that remaining still would provide some sort of relief. Tears began forming in the corners of his eyes as he held his breath to slow his heartbeat. Of everything he had ever endured, he never felt anything compared to this! 

"It's not that bad, Shads. I've had this in me more times than I can count," Sonic said nonchalantly.
But then his voice changed, becoming deeper and more melancholically n'sync with his souring expression,  "---you never get used to it."

The mercenary laughed as he stepped closer into the light, "we'll make sure he doesn't either." 

"---Bastard---" Shadow uttered between labored breaths, "---w-what do you want?"

Infinite loomed over him ominously, his piercing gaze looking down with eerie charisma. He raised his leg to rest it on the edge of the chair between Shadow's thighs, pressing his boot against his buldging erection to cause him further agony. 

"I owe you many things, Shadow the Hedgehog, but I learned long ago that simply taking revenge wouldn't satisfy me. Not when there were worse things I could do."

He grabbed the bound hedgehog's chin while he continued to playfully jab at his equipment with his foot, causing him to expel gasps of pain no matter how hard he tried to hold it in.

"As loathed as I am to admit it, we're very much alike, you and I. We will do whatever is necessary to claim what we desire. Neither of us will accept anything less. And what I want, what I desire, is for you to suffer."

The Ultimate Life Form attempted to focus the chaos energy in his body to his limbs, to override whatever was physically weakening him, but something was blocking his ability to do so, thus preventing him from breaking free. The more he squirmed, the tighter the jackal's grip on his face became and the harder he pressed his boot against his equipment until it was squished against his torso. He could feel the rod inside almost bending, causing infathomable pain that made him choke just to breathe.

If he couldn't escape, he wasn't going to give his enemy the satisfaction of seeing him suffer. He redirected his focus to ignoring the anguish Infinite was inflicting upon him, and seeking an anchor to attach his attention to, he glanced down at Sonic, who was kneeling on the concrete floor completely despondant with an unreadable expression, acting like a lost child locked in the room with arguing adults. His partner's bruises and bleeding wounds filled him with unparalleled rage, which he converted into determination. 

"Get on with it then--" he grunted through gritted teeth. 

The mercenary released his grip and removed his foot from the chair in a single graceful motion, allowing his sensitive member to flop back into position. 
"--Very well." He declared frighteningly. 
Taking a step back, he viciously grabbed Sonic's head and shoved it between Shadow's legs. 

The blue hedgehog was confused as he wobbly peered up to his black counterpart and then over to the jackal, whom moved to a better vantage point behind the metal chair.

"What do you want me to do?" the broken hero asked bluntly, trying to figure out the agenda and his role in it. 

"Isn't it obvious?" Infinite responded before placing his claws atop of Shadow's head and pressing downward in a single, violent thrust, making his body slide in the chair until his tail dangled off the edge, blood trickling down to his wrists and ankles from the barbed wire cutting even deeper. "You get to be on top this time," he followed sarcastically. 

"You mean you want me to...?" Sonic questioned while pointing to himself. Without making any verification aside from the unwavering glare of his glowing eye, the blue hedgehog got the message and shakily stood up. 

"~Whatever you say~" 
He stumbled to get into position, his tongue hanging out the side of his mouth as if he were threading a needle while he aimed his own equipment near Shadow's anus. He ended up having to grab the chair for extra stability as his legs continuously tried to give out from under him while he struggled to shake the feeling of lightheadedness. 

"SONIC! DON'T! HE'S USING YOU!!! FIGHT IT!" Shadow called out to him as the jackal dug his claws into his forehead. 

With his tip at the threshold of his partner's opening, Sonic mustered up a crooked smile with his glazed, half-closed eyes meeting his partner's piercing gaze.

"Fight it? Where's the fun in that?"

He then lunged his equipment into Shadow, not taking the time to first consider lubrication as his priority was appeasing his master, who looked on with intrigue. The Ultimate Life Form couldn't hold back his yelp as the broken hero penetrated him to his full extent, his anus feeling like it was being rubbed raw from the inside while his own equipment felt like it was about to burst. Traditionally in their past intimate moments, Shadow was always on top, but they often traded places to share in the experience and gain a stronger connection. However, after 6 months of celebacy, the black hedgehog was incredibly tight with the pin in his urethra causing him to tense up further, making the sensations excrutiating.

"S-S-SONIC...! Y-YOU CAN'T...LET HIM.." Shadow uttered as he was hammered by his partner, whom acted as though he were in a trance. After several thrusts; however, the blue hedgehog began to tumble, his injuries and fatigue catching up to him. Infinite saw the symptoms onset and slid around to catch him before he could fall. 

"We're only getting started," he stated as he held him in position, "I believe I'll take the reins." 

Sonic couldn't help but grin as he was encompassed in the jackal's embrace, the touch that had become a lifeline he hungered for so many times during captivity. However, his grin was wiped away within an instant as his captor then inserted his massive cylinder into his overused anus. He winced with tears immediately scrolling down his cheeks while the mercenary gradually pushed into him, unprepared for its presence and not physically capable of withstanding it at the time. Still, he knew better than to defy his master, so he did his best to control his raspy breathing and focus on finding some sort of joy in it like he always did.

Wrapping his arms around the broken hero's torso like a boa constricter, Infinite kept him on his feet and directed the blue hedgehog's member back to its designated task, while using the power of the Phantom Ruby to maintain its erection. He then thrusted his own equipment into him harder, creating a domino effect that pummeled Sonic into Shadow. This cycle continued in an out as each participant in the chain felt sensations of different magnitudes. 
For Shadow, it was incredibly painful, the fast thrusts burning his insides while the jolts shook his agonizing member at such a pace, he thought it was going to snap! 
As for Sonic, he had become what Infinite had been molding him into, a tool for pleasuring his master and an instrument against his partner, a living sex toy. His damaged mind teetered on lucidity, parts of his body screamed in pain while others were so numb, they were paralyzed. He had long since lost the will to fight back, and barely had enough energy to stay awake as he was sandwiched between the two most influential individuals in his life, each whom carried great significance in their own right. Meanwhile, Infinite bathed in their torment, the sounds of their moans and whimpers being music to his ears while he was equally excited by the raging hormones. 

"HHHHMMMM!!! Yes... how does it feel, little mouse?" he whispered in Sonic's ear with sadistic charm.

When Sonic first learned to say what his master wanted to hear, it was all for the benefit of survival, now, it had become second-nature to the point even he wasn't aware if his words carried any truth anymore. 

"....it's...a-amazing!....th-thank you....s-so...mmmmuch!" he said softly, trying to direct all his energy to fulfilling the obligations assigned to him. 

The culmination of strides was beginning to reach an apex, one of the grandest scale as the mercenary increased the speed and forcefullness of the motions. The blue hedgehog's peach-colored arms flailed in the air as though they were made of rubber, his head bobbed on his shoulders like a dashboard accessory, and his jumbled thoughts were nothing but a haze, like a thick fog that was impossible to navigate. 

Noticing his toy was losing consciousness, Infinite wrapped his hand around his neck, holding his head up so that the Ultimate Life Form could see his face clearly in the dim light, "Come now, you don't want to miss the finale..." 

Sonic cracked his eyes open, the pulsing in his equipment signifying it was ready. He glanced down to Shadow, whose sack was now incredibly swollen due to the blockage while his anus was oozing red. Their eyes met briefly, prompting the heavily injured, dirty, exhausted hero to model a messy half-smile before gasping to the flow of the hot liquid leaving him for its destination into his partner, while he; himself, received an ample dose from the jackal, whom wrenched his lanky frame between his claws in fervent ecstasy.  

The entrance of the white fluid was akin to vinegar on a wound for Shadow, but despite the pain and humiliation inflicted on him, he looked to Sonic sympathetically, his gentle gaze sending assurance that he didn't hold him at fault for this. 

Unfortunately, the message was not received. Once the ejaculation was complete, the room blurred beyond recognition, all feeling in his body, every voice in his mind, everything became still, silent, like he was miles away from there. Even the Phantom Ruby couldn't hold onto him as he slipped from the waking world into one where joy didn't require pain and reality was just another dream. In this world, he was truly happy.
