Pic not relating to what I'm referring to.
I've been looking months for this one specific exhibitionist doujin and I can't find it.
It's about a school girl who's after school activity is walking around outside naked and having sex with random men, there is a student council group of guys who keep following her around and catching her and scolding her for it, but she keeps running away from them.
At one point she talks to the school nurse for advice on what to do, revealing her hobby to her, the nurse is concerned but ultimately lets her keep her hobby if she's having fun, then after that she goes back to doing it and gets caught by the group again, but this time she fucks all of them to make them give up catching her and enjoy themselves too.
I think the cover was in color, of a girl lying on a bed or something inside, the rest of the doujin was in black and white, I don't believe it was too long either.
