Jeff decided to take it easy from the beginning, so he could later get more into it. He explored the Chronivac a little and soon he found what he was looking for.
"Inanimate options: Became any inanimate object you can think about. Ever wanted to be an object instead of yourself? Just choose from the options below and let it start."
He went to "Clothing options" and there he found the option he was looking for.
"Underwear: Become any kind of underwear cloth. Choose any option, from type, size or colour to owner, condition or wear options."
He then filled the options with all his preferences:
TRANSFORMATION OPTIONS
-Type: Slip.
-Size: Slightly tight (according to owner).
-Colour: White.
-Owner: Ethan Smith (Class 10-B).
-Condition: Extremely comfortable. Broken holes on both sides (front and back) about 1' diameter each. Will always appear clean to anyone except the transformed subject (who will have real perception). Indestructible.
-Wear options: Unable to be taken off by owner. Owner will use both holes as he needs.
TRANSFORMED SUBJECT OPTIONS
-Senses: All on and normal.
-Senses site:
*Touch: Everywhere, specially on front and back holes. Equal front hole to anus and back hole to mouth (subject perception).
*Sight: From back or front side, looking in or out at will.
*Hearing: Sides (left and right).
*Smell: Back hole.
*Taste: Back hole.
-Reality shift: Off (as he wanted to be changed inmediately).
-Awareness: Nobody will know he is underwear. Nobody will think Ethan unable to take off his underwear is strange. Jeff missing will be unnoticed.
OTHER / EXTRA (WRITE)
Owner will ALWAYS poop hard turds, not soft or any other kind.
TIME SET:
Start: When pressing "Enter"
End: 7 days from pressing "Enter"
Jeff revised every point and decided it was perfect. He would be Ethan's underwear for a week, and he would be worn every single second of it. Also, with the holes back and forth, he would feel Ethan's dick and poop on himself all he wanted. He took a deep breath and hit "Enter"
Jeff felt suddenly wrapped around a hot soft surface. He felt hot everywhere, slightly pressed agaisnt it and unable to see what it was due to the lack of light. However, he could smell, and as soon as he did it, the need of sight had disappeared. He smelt what he had inside, and he could only describe it as glorious. He smelt his classmate's asscrack and it smelt really bad, like sweat and a bit of shit, which made him feel really horny. He kept smelling all the time, not worrying about anything that could happen around him. He continued without noticing the time passing till he heard something loud. It was a closing door and footsteps, and then he saw light.
He could now see where he was (although he already knew that). He looked up and saw Ethan's face reflected in the mirror in front of him. He was looking around his almost-nude body, checking his muscles and body hair (or the lack of it). He then sighed and sat. Jeff couldn't understand what he was doing, but as he heard a noise in the back, he went to look there and then he remembered. He had forgotten Ethan couldn't remove his underwear (him), so he hadn't do it in order to sit on the toilet. He smiled all he could as he looked inside the back hole and saw the anus opening and a hard turd start to come out of it. He was ready to taste that big thing from one end to the other. As the turd touched the underwear, he felt its flavour all over his mouth. And oh boy did it taste really good and nasty. He tasted Ethan's shit flavour all he could, trying to avoid it from falling into the toilet. It felt fantastic. Ethan's shit tasted really strong, and he didn't want to let go.
Then, suddenly, as he was tasting heaven, he felt as his ass was being pressed inside out. He remembered he had chosen the front hole to be his ass, so that would mean Ethan's cock was now fucking it. He also felt Ethan was moving it up and down, and he knew what that meant. Ethan was masturbating, so his cock would start to grow and press harder into Jeff's ass. Jeff couldn't but picture himself at that moment and couldn't avoid feel as he was cumming from an inexistent penis. He felt as if he had just exploded in cum, and he couldn't handle it anymore.
He stood there as Ethan finished his stroke session, cleaned his ass and left the bathroom without even notice that Jeff was now part of all it. Oh, boy, was it gonna be an amazing week.
