全裸登校週間 実行委員会

201X...

In this alternate history version of Japan, a top school has a tradition called "nudity scholastics week".
It used to be something students proudly participated in, but that was before cell phones and the Internet.
These days, the tradition has waned somewhat. Nude scholastics week is a liability.

An executive committee is formed to reconstitute the tradition. The committee, comprised of students, shall be solely dedicated to nude scholastics week. This year, Sumire heads the committee. What that means is, for 168 hours, she and her team are the school's cum sponges. Paradoxically, it will cost Sumire her honor to honorably uphold the tradition.
