After looking through the inanimate object options, Jeff decides to get a little creative.
"I think the idea of a journal sounds neat" said Jeff. "To see myself expressed as writing in a journal would be interesting – I feel like I have had so many life experiences already, surely it would be a pretty thick book." Jeff set the duration for a week. "Perhaps someone will find me and read me. I wonder how that will feel."
Jeff programs the chronivac with all the requirements, and alters reality so everyone expects him to be away at a friends house for the week. He sets the transformation to last 10 minutes. Jeff hits enter, immediately undresses, and sets on his desktop.
His dick slides down the gap between his legs, sealing the gap as it goes. It comes to rest under his feet. Jeff's feet start to flatten out and merge together. They turn into cardboard wrapped in the leather of his skin, forming the back cover of his journal body. Jeff feels his legs start to weaken. They thin out ; as if being rolled between rollers. Jeff grabs the edge of the desk, as his legs can't support his weight. His paper thin legs start to fan-fold on top of his flat feet. His three foot long legs stretch into hundred of feet of paper. The flattening moves up his legs, finally catching his balls. They flatten with the rest of him, neatly stacking themselves on the stack of paper. The act of them flattening sends immense pleasure down his spine (which just formed the spine of the journal).
The flattening continues, taking his torso and well sculpted six-pack with it. "Hopefully somebody reads about how proud I was of them" he thought.
As the flattening rolls his chest, Jeff stops breathing. The pressure is too great. But as he is mostly paper now, he doesn't need oxygen.
Jeff's arms shrink and flatten out. He can no longer support his shoulders and head; so they tumble off the desk and land on the top of the paper fold. The left arm turns red, the right one turns yellow. They become place markers; and insert themselves between his folds.
The flattening moves up his neck; stopping just under his chin. Jeff's brain starts to drain out of his neck in the form of ink running down through the paper. The ink forms the story of his life in words on his pages. His head, fully deflated, collapsed onto the newly formed cover.
Suddenly, Jeff shakes as all the outside folds of his paper rip apart to form individual pages. The shock was excruciating; as it felt like Jeff was ripped apart at every inch of his former body. The edges of the pages remain red; and look like premium rag paper with an accent edge. The opposite edge of his paper fuses back with his book spine, ending the pain. Jeff finally felt whole again.
Jeff's face sinks into the cover until it is only a leather imprint on the surface; a smirk on his face. His dick flattens out into a leather strap, which is attached to the back cover. It folds over the page edges, and tucks itself into his mouth on the front cover, forming a clasp.
"Now let's see if anybody finds me, and is curious enough to read me" mused Jeff.
