Jeff thought for a while, debating on things like a pair of panties, or some kind of swimsuit. However, after a lot of thinking, he finally made his choice. "Why be something that a woman could wear... if I could be put inside of them?"
He searched through the Chronivac, and found what he wanted. A Tampon. While he didn't quite know what a tampon was, he knew it went inside a girl's vagina, and that was good enough for him.
He started to insert his options. He decided to set the time limit to a month, and set it so he'd be capable of being reused infinitely during the duration. He also set it to where he'd be shrunken down to around half the size of the girl using him, and that he'd always fit painlessly into the hole.
He ended up inserting:
Absorbancy rating: Ultra
Auto-Reset: After use
Time Limit: 30 days
Reality shift: On
Subject aware: Yes
Communication: On
Regress for Fit: Only if needed
Size adjust: 50% of wearer's size
Senses: All on
He looked back through, making sure they were correct. After verifying, he clicked confirm. A progress bar appeared on the screen, showing the progress of his changes. "Let's hope this works."
He watches the bar move along, taking his clothes off in case it matters. The bar hit 90%, and he minimized the Chronivac window and got out of his chair. "If it works, it's time." He closed his eyes, and took a deep breath as the Chronivac finished up.
