Keep going

It’s not enough. He needs to be bigger, so much bigger. You press the button again, speeding up his transformation. “What did you do?” Dorian’s voice quickly turns from pleasure to fear. “Stop! I can’t take it!” even though he seemed to be enjoying the change before, it’s quickly becoming too much. His cock grows rapidly, exceeding anything remotely feasible in seconds. Dorian can barely form words; his mumbling slurred and incoherent.

You decide to untie him. At this point, he doesn’t even seem able to escape. Your hypothesis quickly proves correct when Dorian attempts to get out of the chair and run. He makes it a few unsteady steps forward before he falls, out of breath from the exertion. If he were to lean forward, he could easily suck on his head without needing to bend down.

“I… I ca- I… stop… can’t take more…” he wheezes. Every attempt to stand back up is met with failure. Eventually he tries dragging his body forward but that too quickly becomes too much. “Help…”

Dorian is practically rooted to the ground. His cock has stopped growing, though it is much too late for him to get any relief from that fact. It eclipses him completely; his body stuck pressed against its shaft. He is no longer human in any way that matters. He cannot move, he can barely speak, but still he lives. You care for him, feeding him and cleaning up his messes. It’s what he deserves. To live however many years he has left completely unable to do anything but cum.
