Getting more than expected (bimbofication)

Akiko has always been fascinated by the big breasts of women from other countries. She was pretty average in her breasts size, with a nice C-cup, but compared to some women on porn sites, she was ridiculously small.

One day, as she walked in a strange new store in Tokyo. Selling all sorts of stuffs with little to no common factor. A remote, makeup, sexy clothes, table board games, ...

She was welcomed by an old lady who showed her two rings in a box.

"These jewels will give you what you seek, miss." She said.

"They're not pretty, for earrings..." Akiko commented, looking at the two silver rings.

"Oooh... they're not earrings, dear. They're for your little buttons." The old woman told her, pointing at her nipples.

The girl turned red at the idea of where they were supposed to go.

"I-I'm not pierced there... It's... It's so shameful..."

"It's ok, then, you can have them and you'll pay me once you put them on."

With that, the old woman put the box in her hands and pushed her outside.

"I... Uh ? What ?!?"

Akiko walked back home confused, with the box in her hand. She put it on a furniture, not knowing what to do with them. But as time passed, the idea of having those rings hanging on her nipples slowly find their way in her mind. It was so naughty, so sexy...

After a month, Akiko pierced her nipples and put the rings on. They were so big, she felt ridiculous. But slowly her breasts grew, looking really fine with the jewels.

Weirdly, her hairs also started to take a lighter tone. But she didn't mind it much. She wanted to show her tits, they were so big, so pretty... She dreamed about it, fantasized about it, ...

After three months, Akiko started to go to hot spring, where it's normal to be naked, and she enjoyed seeing jealousy in other women's eyes. But if her breasts stopped at G-cup size, which was huge on her small frame, her hairs continued to lighten, reaching a natural honey blond. Her eyes also were changing color too, from brown to blue, and her hips widen with a round butt and large thighs.

Akiko realized too late that she was losing knowledge. It was hard at first to remember the course she studied the day before, during the tests. But it quickly spread as her grades were taking a toll. Basic math started to become difficult to do, complex words couldn't be found in her memory, and there was no chance to know anything science-y. Instead, her mind was constantly assaulted by naughty thoughts, leaving her horny all the time.

She tried to take off the piercings, but they were sealed shut, stuck on her nipples. She couldn't even cut them, like they were made from an unbreakable material. And so, the last changes took place, her hairs turned platinum blonde, her eyes deep blue, and she got the most obscene hourglass figure. As for her mind, she lost all shame on nudity and sex, constantly thinking about carnal pleasure, while her knowledge of high school and above were completely wiped off.

"It's your scene, Kiki. Are you ready ?"

"Yaay ! It's Kiki's turn !"

Akiko hopped on the stage of the porn movie. Three muscular guys were waiting for her, naked. She couldn't wait to be fucked by all of them at the same time. It was the joy of her life, getting fucked all day long and being seen naked by thousands of lustful men and women.
