Clinging to the covers, Sonic's eyes cracked open to find he was alone in the dimly lit infirmary, tucked in snuggly with clean blankets and soft pillows. 

"Infinite?" he mumbled drowsily as he peered around the room with blurry eyes, his head pounding and feeling like it weighed a ton. "H-hello?". 

With a disappointed sigh, no one answered. He sat up in the bed slowly, letting the dizziness subside before attempting to stand on his own. He proceeded to use the IV stand as a crutch until he could obtain some balance, taking into account how the room was unchanged but everything felt different. "How long was I out?" he wondered to himself, his mouth tasting unbearably dry, his stomach completely hollow, and his muscles overly strained just to stand. 

Although he could easily mash the call button in order to summon one of the guard robots, he instead opted to do as much as he could on his own, his defiant spirit carrying him even now. After hobbling into the bathroom, he was stunned by the image that stared back in the mirror. His quills were an absolute mess, his face was a blend of red and purple, he had lost weight, and something felt...off. He spashed his face with water, and as he did so, flashbacks started randomly appearing before his eyes. His lips swallowing something shrouded within white fur, hearing the cries of a voice not his own while he gorged in a sensation he had not experienced in what seemed like a lifetime. 

"What...what happened to me?"

He began splashing his face even more vigorously, holding his breath as more memories began flooding in. NONE OF IT MADE SENSE!!! The images that kept appearing out of order were so vague, almost transparent, and the feelings that came with them didn't match. Heat and cold. Joy and sadness. Fulfillment and regret. All of these were bundled with depictions of chains, blood, and ghostly figure. Anxiousness to know what they all meant overtook him, his hands grasping the side of the sink as he hyperventilated. He became so desperate that with one giant heave, he dipped his head into the amassing water. Closing his eyes, he focused as hard as he could on what he was missing. 

Then, he remembered. 

Somehow, he had found his way to one of the monitor rooms. 

"What was I doing? Where was Infinite?" 

He was wandering aimlessly, calling out for anyone who could hear.

"I'm not supposed to just roam around. WHAT WAS I THINKING?!"

Then, he stopped short in his tracks as he heard the intense screams of a voice he recognized. Someone he thought he'd never see again. Looking on at a monitor, he was stunned to see Silver being jabbed by cattle prods while suspended in one of the torture chambers. 
"How?..." Sonic thought as he stared in awe at his friend being brutally interrogated. 

Gasping, the blue hedgehog lifted his head from the basin, the shock slowly setting in. "Silver...is here?" he questioned, trying to piece together some rationality of what he witnessed, "did...did he come for me?" Sonic's head then began to throb even worse as he couldn't understand why the memory was so elusive. Was Silver really on the Death Egg or was he having some sort of fever-induced hallucination? Did Eggman's experiment on him make him see things? If it was true, and Silver was here, was it possible his other friends could be as well? 

The thought of being taken away from this place threw the broken hero into a vortex of mixed emotions that spiraled out of control. Part of him was overjoyed, believing he could finally go home again. Thinking of those lush green meadows and gorgeous landscapes against the cold metal environment he had grown accustumed to made his heart ache for them even more! On the other hand, he kept thinking of the tender touch of his master. That warmth that shielded him from the darkness and kept him from falling apart. How could he possibly consider leaving him?! Then he started to take into consideration what he saw and process the weight of it. Silver was confined, being electrocuted for information. If he was part of a rescue party, it clearly failed. Perhaps he was a prisoner of war like so many others? 

Then, like a bolt of lightning, Sonic felt a sense of dread overtake him as the patchwork of memories gradually aligned. They were so powerful, so vivid, that he stumbled backwards unto the floor, burying his face into his hands while the magnitude of what happened trickled through his subconscious, letting him relive every sound, every taste, and every touch of what his mind tried to block out.

Although Infinite's decision to withhold intimate activities from Sonic was sound for the benefit of his health, it nevertheless left the hedgehog's body feeling "neglected". From having such wild sex on a regular basis to obstaining for over a week, the fever removed all rationality while his own hormones took the reigns and directed his hands to caressing the white fur of the bound victim, fur that danced between his fingers and reminded him of his master. 

Silver wriggled in his chains, straining to see through the blindfold, but unable to do so. "GET YOUR HANDS OFF OF ME!" he screamed as the paws traced up and down his torso before resting on his petite chest. There was barely any fat tissue in the time traveler's breast, but the nipples were still easy enough to find and apparently were quite sensitive to teasing. Silver's mind began racing as never before had he been touched in such a way. The tingling sensation made him immediately struggle more as he tried to resist what was being done to him. 

Sonic remained vocally silent, but couldn't help panting at the excitement of fondling another for a change. He slipped one of his hands downward along his friend's form, where he began massaging the lump that housed what he desired. "AHH-AHHH!!! STOP!!!" Silver cried while he futily tried to close his legs; however, the shackles that fastened his ankles to the floor left little-to-no room for any movement, thus preventing him from protecting his private area. Sonic barely recollected some sort of device strapped on Silver's forehead, maybe something to negate his psychokinesis? At any rate, the white hedgehog was unable to use his powers to defend himself, and with his stubbornness keeping his shaft inside, the blue blur instinctively inserted his finger into the bound one's sheath, tantalizing the occupant to come out of hiding. 

Silver began moaning and gasping, unable to contain his arousal nor control how his body reacted to Sonic's magic hands. "DON'T! PLEASE!!!" he pleaded, his voice breaking from embarrassment and shame. His reaction made the blue hedgehog recall his own early days with Infinite. How clearly he remembered the humiliation of his body disobeying his mind, and how quickly the burning of his insides, the taste of blood and cum clinging to the corners of his mouth, and the lingering agony of bite wounds over bruises replaced such frivolous notions of pride during his master's most merciless times. Although he learned to take pleasure from the pain, he didn't want to inflict such anguish on his friend. His only desire here was to make them both feel good and to satisfy his ravenous carnal urges. In his mind, what he was doing was completely justified. Silver was a prisoner just like him, he had been tortured, just like him, and they had no way to escape. He didn't know what the powers-that-be had in store for the time traveler, but if any of it was akin to what Sonic endured, he could at least make this moment a pleasant experience. An escape, in a sense, for them both. 

With that, Sonic slipped his lips over the tip of the succulent flesh that finally reared its head, slurping and suckling as he slowly moved his face close to Silver's abdomen before jutting backwards and repeating the cycle. The white hedgehog was in absolute bewilderment!!! So many thoughts rushed through his head, "WHAT IS HAPPENING TO ME?! WHO'S DOING THIS?! WHY?!?!?! IT'S WRONG!!! IT FEELS SO WRONG!!! BUT---I...." His back began arching as a wave of heat flowed over him. His paws started sweating, his toes curling, and his ears growing hot, ll while he could feel his tail twitch from the excitement. "...am I...enjoying this?" he questioned in his mind as his animal instincts to embrace the urges started to take over. 

Meanwhile, Sonic was enjoying every second of it. Infinite's equipment was always so large that providing oral service was a painful and unpleasant task that often left his jaw sore and his throat aching. Being of the same species, Silver's size was more adequate for the blue hedgehog to encompass fully in his mouth and some in his throat without choking. The taste was also so very different. While his master's scent was rather musky and masculine, the white hedgehog's was sweet and earthy. The enriched flavor reminded him of him and made his shaft even more desirable. Becoming intoxicated by it all, Sonic picked up the pace, sucking harder and faster than his friend could handle before he inevitably spewed his juices into the blue blur's mouth in an incredible amount! The first release in his life.

Silver's heavy breathing overlapped Sonic's gentle moans as he drank the silky treasure until it stopped leaking. "W-why?" Silver uttered, "Why did you do that to me?" 

Sonic knew if he spoke that there was a strong chance his friend would recognize him, and he wasn't ready to explain himself nor was he sure if he even could. After wiping off his mouth, he stared at Silver's perfectly contented shaft and realized his own equipment had been ignored for a very long time. The heat he still felt rushing through his veins and the raging desire to continue led him behind the suspended prisoner, where he was pleasantly surprised to find the white tail erect as if it were inviting something to enter. Sonic took this invitation and began licking the puckering rose of his friend's anus with great delight. 

Once again, the time traveler was astonished by another point of his body being exposed as extremely sensitive. "GAH!! AHH-AHHH-HAH!!! WH-WHAT ARE YOU DO-ING NOW?!?!?!?" he stuttered as he quivered from the physical anticipation of another arousal. Sonic fondled his own shaft with one hand while holding Silver's tail up with the other, his tongue working its way over the hole as he accumulated as much spit as possible to insert. Feeling the hotness of the stranger's tongue entering him, the white hedgehog let out a chorus of moans. He never knew such a sensation could feel so good! Part of his body wanted to relax and indulge in the soothing, wet stimulations while the other part was on peak, ready for whatever came next. His mind had went from fighting back to directing all of his focus into registering the sensations and trying to understand them. 

Satisfied with his work and ready himself, Sonic stood up and pressed his cylinder into the tender tight anus of his naive friend. 
"YAHHHH!!!!" Silver screamed as he was torn from the peaceful ecstasy and thrown into the wrenching pains of his ass being stretched. Sonic knew it was painful for Silver, but he also knew the glorious pleasure that awaited on the other side for them both. Working him open, he humped slowly, pushing further in with each thrust. Silver's moans and yelps combined as he was penetrated, sweat now forming all over him, drool leaking from the side of his mouth, and tears streaming down his cheeks as the horrible stinging and burning sensations increased by the moment. For Sonic, the pressure of his length being squeezed in the moist warmth was absolutely amazing! His heart was racing, his muscles ached and trembled, but he he couldn't ignore the call from his crotch. "MORE!" he thought to himself as he looped his arms around Silver's waist, holding him tightly while trusting as deeply as possible at an even faster rate. 

"S-STOP!!! PL-PLEASE!!! IT'S---TOO--M-MUCH!!!" the white hedgehog cried while he bounced in his chains; however, his pleas fell on deaf ears as the sex-crazed former hero, whose fever had reached a dangerous level, was solely focused on obtaining even more heat. He thrusted harder, faster, harder, faster, gasping and groaning as Silver whimpered and screamed. His eyes rolled back every time the blue blur hit his sweet spot, finding overwhelming pleasure in that special area he never knew existed, which made him cum every single time. Despite having multiple releases as well, Sonic couldn't stop! He just kept going, like his body was reacting on his own while his mind had shut down. Blood had been trickling from Silver's anus for a while, but even that didn't make him yield. He just kept going and going with a blank stare on his face and monotonous moans escaping him. 

Time lost all meaning as they were caught in this loop of pain and unquenchable desire. Finally, without rhyme or reason, it stopped. The sound of raspy breathing and dripping fluids being the only noise that resounded in the dark, damp cell a thud echoed on the floor. Silver's blindfold had become so wet and heavy from his tears that he was able to shake it off a bit in order to peak at his surroundings. Everything was foggy as he teetered on the edge of unconsciousness; however, he tried to concentrate as best he could and hold on for a few more seconds. 

Peering around, he caught a glimpse of blue quills laying on the floor behind him in a puddle of white liquid, the form unmoving. Despite the impairment in his vision, the shape of what he could see was very distinguished. "S-Sonic?" he questioned deliriously before falling limp in his chains, thus joining the blue blur in the realm of sleep.
