Knuckles ran with Sonic as quickly as he could, bringing him back home. Once they arrived at Sonic's house the door was locked, but the red echidna simply punched his way into the house. Once they were both inside, the Chaos Emerald and Sonic safe, he felt as if his job was finished…but his good nature stopped him from just leaving. He felt he had to help the blue hedgehog. In a firm voice, the echidna spoke "Here, let me help you get out of that…outfit." Knuckles then slipped him out of the demeaning but erotic attire, leaving the hedgehog in his normal state, or at least as normal as he could get at this point.
The muscled red figure realized something after a few moments of being in the home, there was no one else here…Amy and Tails were nowhere to be seen, and a lot of the furniture and items were missing from the room. He assumed they may have moved, but why would they? These would be questions for another time, the echidna then slowly lifted Sonic in his arms, bringing him to the bathroom and laying him in the porcelain tub, calmly running the water.
Sonic remained mostly silent during this whole ordeal, almost as if he was constantly in a daze unable to wake. He accepted the treatment from the dreadlocked male, feeling Knuckles begin to wash warm water over his bruised and even thinner than normal body. This treatment made the abused hedgehog's cock begin growing erect, unable to help himself after being used as a sex toy for so long, and even beginning to enjoy it. Just the slightest amount of kindness aroused the hedgehog, making him want to reward the large echidna for saving him from his captor.
Sonic leaned his head over the edge of the white porcelain tub, pressing his mouth submissively against the echidna's sheath. He began to use his warm and wet muscle to lick across it, trying to incite even the slightest amount of pleasure to make his crimson cock appear. The blue cum dumpster placed one of his gloved hands onto Knuckle's firm waist, Knuckles unable to resist the licking, Sonic saw his gigantic crimson cock unsheathe, realizing it was even bigger than Shadow's.
"W-What are you doing Sonic? We can't do this! This is wrong!" He barked, Sonic remained silent like he has been this entire time, Sonic knew when a man wanted something by this point…and Knuckles wanted him. Knuckle's cock fully unsheathed itself as a result of the submissive licking, his balls dangling proudly below the absolutely massive shaft. Sonic then wrapped his hand around the base of that bulging cock that was big enough to even make a horse jealous. He pushed his warm maw against the head; suckling it in, his tongue dancing around the rim and slit.
A blush began streaking across the already red face of Knuckles, just making it an even brighter shade as he enjoyed the sensual reward for rescuing his friend. This along with the Chaos Emerald was enough to make anyone jealous. Sonic responded to his blushing only by taking his cock deeper, allowing it to slide down his warm muscular throat expertly, not gagging even once. A chill shot down Knuckle's spine as he saw the hedgehog look up at him with his gorgeous green eyes, his only response being to place his muscular hand on the back of the blue hedgehog's head, pressing him down further on his now throbbing and dripping cock.
Sonic's saliva was now nearly coating every inch of the massive red cock, he could feel every inch throbbing down his sopping wet throat as he took the echidna as deep as possible. When he reached the base of that beautifully sculpted cock, he began licking at the proud sack dangling below it, extending his tongue as best he could to massage the beautiful crimson jewels that Rouge wished she could handle. Sonic moved his gloved hands to Knuckle's defined ass, gripping it firmly as he began bobbing his head up and down, feeling the throbbing shaft slide in and out of his wonderfully hot and wet hole.
As Knuckles felt his cock being engulfed fully by the hedgehog, he couldn't help but begin moaning deeply, his voice echoing through the bathroom as he felt his gigantic veiny dong being pleasured by the little submissive Sonic. It was all enough to put him on edge right then and there, but just as Knuckles thought it couldn't get any better, the sapphire hedgehog dipped his gloved hands into the warm water, getting them soapy and hot, only to place them on the echidna's large dangling sack. He began tugging and massaging at those wonderful crimson orbs as he bobbed his head up and down repeatedly over the gargantuan red shaft.
Knuckle's legs nearly buckled under the intense pleasure he was feeling, the wet hands, the hot maw…it was all too much to handle. His strong hand gripped onto the spiny blue hair of Sonic as tightly as possible, holding himself up as he was pleasured so professionally. Knuckles realized how much Sonic really trained during his time as Rouge's captive, and perhaps it was worth it. But after just a few moments, the echidna couldn't restrain himself any longer, and let out a pool of cum into the hedgehog's mouth and throat. His body nearly going into a spasm as he felt himself unload those gigantic red testicles into that beautiful hole. Sonic didn't choke whatsoever on the massive load, being well trained to take such large torrents of seed.
Sonic, after cleaning off Knuckle's freshly relieved rod, let it slide out of his mouth and flop between the red echidna's legs, a trail of saliva following from the hedgehog's lips as it fell downwards, the veins still bulging along it. Eventually, it found its way back to the cozy sheath, Knuckles at a loss for words nearly collapsing onto the ground after being pleasured so well. "S-Sonic I…d-don't know what to say…"
After a few moments, the echidna emptied the bathtub and dried off the submissive carefully. He proceeded to wrap the towel around Sonic's freshly cleaned body, leading him to the bedroom after, and allowing the poor blue soul to rest a while after his long captivity. Knuckles had no idea what to do from here, where he should get help for Sonic, or where to find Amy or Tails. He couldn't just leave his friend alone in this situation, and made it his next mission to find him aid.
