As Joe sat there, stewing away in his captures balls he wondered how it could come to this. In a few moments he was going to be nothing but another white, sticky load for him and there's nothing that he could do about it. No one on the outside knew that while they sat there, the last of Joe was slowly being broken down into sticky jizz.
He'd noticed the cute stranger watching him earlier from the other end of the carriage on the ride home, smiling a little as he eyed Joe up and down, making his intentions clear. This wouldn't be Joe's first public hookup with a stranger so he was confident he knew what he was doing. He smiled back at the cute stranger, eyeing up his crotch and looking him up and down.
Eventually he saw the hot twink get up and move for the bathroom, his shorts showing off his thick bulge and juicy ass. After a few moments Joe followed, entering the unlocked bathroom, which was the last room he'd ever see on the outside world.
The hot stranger smiled at him and beckoned Joe to get on his knees, which he gladly obliged. He felt the man's thick package, which was rapidly hardening under his shorts. Once it was completely hard the stranger flopped out his thick 8 inch cock, which Joe knew would be a challenge, but one he was more than willing to take.
He slowly began sucking the beautiful dick, feeling it pulsate and lick sticky precum into his mouth. From above he heard stifled moans as his tongue danced around the tip of this enormous member. After a few minutes of continued licking, kissing and jerking of the gorgeous stranger's hard cock Joe felt him tense up and let out a final, sensual moan. He felt warm cum leak into his mouth and down his throat that slowly began to fill his stomach. He emptied out hot seamen directly into Joe for almost 20 seconds, and by the time he was finally drained Joe's stomach bulged out, feeling full to the brim.
"Sorry about that, my meals always get broken down into heavy loads" the man said, winking down at Joe. Unsure of what he meant Joe brushed the comment off, slowly standing up and going to walk away. Though he was cut off as he tried to take his hand off the still large, bulging penis. He looked down at the hulking member and saw with horror that his hand had been completely engulfed by the cock slit without him noticing.
He tried to pull it out but this only succeeded in pulling his left arm further into the now gaping slit. He looked up at the man who just moaned with pleasure and smiled at him, he appeared to be enjoying it more than the initial blowjob. Joe desperately fought to reach the door and open it so someone would see and help him but he couldn't reach, by now he was almost up to his shoulder as he continued to be pulled further into this ravenous cock.
Once his arm was fully engulfed the top of Joe's head began to be consumed by the stranger's penis. He could feel his arm being smothered with slimy precum, which made its journey down the tunnel that was this predators cock a very slippery ride. "Stop this!" Joe shouted as his head was pushed further inside. He realised that the only way he could escape was by screaming for his life while his mouth was still free.
"HELP!" he screamed, "THIS GUY'S TRYING TO-" But it was too late, Joe's mouth was smothered by the stranger's cock, which only served to silence his screams for help to the outside world. As his head was fully engulfed, Joe's predator swiftly stripped him down, leaving his clothes and shoes on the floor for some janitor to find and clear away. The rest of the ride went down smoothly.
Joe's body was swiftly consumed and slurped down by the stranger's cock until all that was left outside were his feet and ankles. Then with one final flex Joe was sucked completely into the man's ravenous cock. From there, Joe's body made his way down the dick, which was tight and reeked completely of cum that filled all his senses.
As he reached the end of the tube, he felt a hole open up and slowly drop him into a warm, fleshy chamber that smelt even more strongly of man juice. Once he was deposited in what he was sure was his pred's balls he felt him pull his shorts back up and return to his seat. As he walked, Joe was sloshed around inside his balls, being coated in sticky cum that felt like it was seeping into his skin.
As his skin absorbed the cum he slowly felt his body become number and looser, as the process of conversion into cum began. No one on the outside noticed that the pred's balls were abnormally large in his shorts, as the held captive the unfortunate man who was about to be turned into cum.
Joe's fingers and toes started to drip with cum as he watched them melt away and join the liquid that he was churning away in. He desperately tried to find the hole that he had fallen through to get in here, but it was nowhere to be found. He tried to punch on the warm, fleshy walls of the stranger's balls in hopes that maybe he'd get out or be let out, but no such luck came.
As he gave a hard punch on the walls one of his hands burst into cum, coating the rest of his body in more of the liquid that would lead to his demise. He thrashed his legs around in an attempt to get out of the numbing liquid but this only caused them to give into the cum as well, exploding into ball batter as he lifted them above the pool of jizz. The only solid parts that remained were Joe's torso, arms and head, which were slowly turning milky.
At that moment the pred reached his stop, he adjusted his trousers and stood up, walking to the exit. This only served to throw what was left of Joe around in his balls, hastening his demise. He watched helplessly as his arms melted into the liquid before him, and his body started to lose shape.
His final hazy thought was "I can't get out of this" as his body disintegrated into the pool of cum that used to be him. From the outside world the man felt Joe completely dissolve, as he was repurposed into jizz for his next unwilling prey to swallow.
"God turning horny guys into cum is always amazing" he said, feeling up his balls with his hands. There was no trace of any man in there now, Joe had been fully converted into a load of cum inside the pred's balls. "Onto the next one š¦š" the man said, setting off into the night.
