A little bigger (D-cup) The New World of SwapTech chapter 8 by deleted_user

Jonas stood in front of the small display case at the SwapPort gift shop, reading the label for the third time.

Cosplay Chest Enhancement — Increase or decrease bust size by up to three cup sizes. Temporary. Reversible.

He looked down at his chest. The yoga planes and tank top did nothing to hide the curves beneath. He was... what, a B cup? Maybe a C?

I could make them bigger.

The thought was strange. He'd never thought about breast size in his life, except to appreciate them on other people. But now — now he had the option to change them. To see what it felt like.

This is purely scientific. I'm just curious.

He grabbed a small patch from the display—it looked like a square of clear medical tape, no bigger than his palm—and brought it to the counter.

"Just the one?" the clerk asked, raising an eyebrow.

"Yeah," Jonas said, trying to sound casual. "Just curious."

"That'll be fifteen bucks."

Jonas paid, then retreated to the restroom. He locked himself in a stall, stared at the patch, and peeled off the backing.

Okay. Where does this go?

The instructions said to apply it directly to the sternum, just above the cleavage. Jonas pressed it against his skin, felt a cool tingle spread through his chest.

Then he waited.

Nothing happened for the first few seconds. Then he felt a warmth, a gentle pressure, and looked down.

His breasts were growing.

It wasn't dramatic—no sudden bulging, no comic-book expansion. But over the course of about thirty seconds, he watched his chest swell, filling out the tank top in ways it hadn't before. The fabric stretched, the neckline pulled tighter, and when it stopped, he was noticeably bigger. Probably at least a D cup.

He touched them, experimentally. They were warm. Soft. And his.

Huh.

He looked in the mirror. The woman staring back had a considerably more impressive chest than she'd had five minutes ago.

Okay. That's... that's something.

What does Jonas do next?

- Leaves the restroom and sees how people react to his new look.
-  — maybe he wants to try height or skin tone too.
- Regrets it immediately and tries to reverse it.
