Taking a detour through a few buildings, Alex figured that at this hour of night, no one would be around within the buildings themselves. It was becoming a burden to run for him, his limbs weakened and his head carrying much more weight. Stopping for a moment beside a water fountain, he tried to catch his breath, lifting his top lip up to help speed up the process. Once he'd rested for a minute, Alex took off running again, and as he turned the nearest corner he ran straight into a large figure, knocking him to the ground.
As his head hit the ground, a loud ringing sounded from what was left of his ears. He groaned, putting a hand to his forehead, and looked up to see none other than Jack. "Toilet boy! Where are you headed off to at this hour?" he gasped, his surprise quickly melting into a sneer. "You're quite far along now... wouldn't want you to be in the wrong place when you put down roots, eh?"
Alex weakly stood up and tried to back away from Jack, but being near him was sending those thoughts rushing back into his mind. It was his master, here to let Alex fulfill his purpose. He wanted, no needed Jack to use him, and as Jack reached out a hand to grab Alex, all the resistance in his body melted away, changing instead to anticipation.
Jack led Alex back down the hallway and into the nearby bathroom, which he quickly realized was the bathroom where he'd spied on Jack. "What a fitting spot," Jack chuckled, kicking open one of the stall doors to reveal a ready set of pipes. "They must have been replacing the toilet here... I guess I've found their replacement for them now haven't I?" Jack shoved Alex into the stall, who instinctively squatted over the pipes with his huge ass. The pipe immediately began to work its way into Alex's ass, and as soon as it made contact a rush of ecstacy washed over his entire body. His knees sank to the ground as the pipe went deeper than ever before, merging with his insides like it should have been.
All over his body, Alex knew that this time would be the last shift between humanity and toilet-hood. His arms clasped his torso and merged inward, his legs sinking down to form the base one last time. His mouth extended even further, a toilet seat forming from his lips to sit under the lid that had been his upper lip. He felt his ears, nose and eyes dissolve into his face as his lever grew larger, and within a few moments he resembled a toilet, albeit not completely changed.
Jack slid his jeans down, grinning as he lifted the lid and planted his ass firmly on Alex's seat. Groaning, he let the shit he'd been holding in slide out of his ass and into Alex's mouth. Alex's mind was swimming in excitement - the shit tasted so good! And to have a hot guy sitting on him and using him... the pleasure of that was already enough to keep the remnants of rationality from screaming in terror. If he had vocal cords, he'd moan from the ecstacy of having his mouth fill with shit, and he could sense that wouldn't be all that Jack had in store for him.
As Jack pressed Alex's lever down to flush his dump away, Alex was filled with the most powerful orgasm he'd ever experienced. His form nearly shook as his body was rocked by wave after wave of pure release. He could feel the shit moving through his digestive tract - no, pipes now - as the shit rocketed out of his old ass, and Alex loved it. He was still being rocked by waves of pleasure when Jack began to masturbate, the bulky jock moaning as he thought of how fitting this punishment was.
As Jack cummed, Alex got to taste his master's cum once again, and it tasted even better than before! He was so excited for his next flush, and he was so happy to clean up his master's mess. It was his purpose in life, what he was born to do, and when Jack flushed him again after cleaning up his mess, Alex literally shook from how powerful the second orgasm was. It took a few minutes for his orgasm to subside, but as Alex's rational mind began to return he began to realize what had just happened. Jack stood up, staring back down at the toilet that had been Alex and winked. "I hope you're excited for your new life, slut. Enjoy the cum, piss and shit you'll be collecting," he snickered, walking out of the stall and exiting the bathroom.
