Corruption - Chounyuu Transformation

This is a collection of CG illustrations in which girls with big breasts are captured by a major pharmaceutical company and experimented on to make their breasts even bigger.
This work includes both Japanese and English versions.


* Synopsis
Yumi Otonashi is a college student with big breasts.
She goes to an interview to be a part of a call center at one of the biggest pharmaceutical companies in Japan.
The interview goes without issue, and she is told on the spot that she has been hired. Yumi is relieved. However, she is taken into custody immediately after.

This particular company has a dark side: it develops illegal and special drugs and distributes them on the black market.
Yumi has been chosen as a test subject for the "breast enlargement drug”.
This drug makes Yumi's exceptionally large breasts increasingly larger, heavier, and more massive.
In addition, her breasts were modified to spurt milk out endlessly, and she’s also trained pleasure men with various lewd techniques.
While reluctant at first, she gradually grows stronger urges to pleasure herself with her enormous breasts.

When Yumi's physical and mental modifications reach their peak, she is "kept" by a pharmaceutical company executive.
Under the guise of "entertainment," "hospitality," and "presentation”, Yumi is "ab*sed" day and night.
Her days involve her being displayed in front of many people, being used as a breastmilk dispenser, and sometimes she was even used as a sex toy.
While her days are incredibly harsh, her altered body still seeks pleasure.

Will Yumi ever escape from this endless hell?
