STORY

During the university summer break, I was wondering how to spend my time with no particular plans when my roommate Akira becomes a girl due to TS syndrome!

If she climaxes 100 times within 30 days of TS syndrome, her gender will become fixed!?

A debauched summer life with a sudden girl (TS) begins...

Although she is a girl now, she used to be a boy curious about naughty things.

Unable to just do nothing after undergoing TS, she starts to use her girl's body and becomes increasingly erotic!

And then, at places like massage parlors, lingerie stores, on trains, and so on, even strangers might... do this and that to her...!?
