He stumbled across the "Vagina" option, and began to get an idea... as well as an erection. "I can become a girl's vagina?? Oh this just sounds great!"
Without skipping a beat, he let his horniness take over as he began to type out his changes, while occasionally taking a moment to rub his penis. He set it so that he'd get to choose during the transformation who he becomes part of, and allow himself to change.
==============
CHRONIVAC SETTINGS:
Target: Jeff ()
Function: Vagina
Shrunken on entry: Only if needed
Regress/Progress to Host's age on attach: True
Change host's continence level: False
Host sees target as normal: False
All else see target as normal: True
Can use bodily functions separately: True
Can detach at will: True
==============
He set it up to where he'd take on the entire vaginal area, including both the womb and bladder. He doesn't even double check his settings, he just wants to get right into things. Jeff clicks confirm, and the Chronivac starts it's work. As it's approaching the 50% mark, it provides him with instructions on how to utilize the transformation.
"Instructions on attachment:
If the host is female, Simply push into a female's vulva and enter inside. The Chronivac will hollow out the replaced functions, allowing the user to fit their entire body inside and take on the role.
If the host is male, the connection is made inside of the penis, with the target replacing the entire internal systems but leaving external unchanged.
With the selected settings, both the host and target will have their bodily functions intact. It may be recommended to wear incontinence briefs during connection."
He read through everything and made sure to memorize it all, as the change completed. It was time for him to connect to someone, and become one with their genitals...
