I'm looking for a manga.
I remember there were 2 guys that were helping with some work and 1 girl.
She had purple hair and a triangle mouth like picrelated.
She was always masturbating and was very nonchalant about it.
Does that ring any bells?
Oh, last chapter at the time I remember reading it they were stuck on an island.
It's Henjo: http://myanimelist.net/manga/87466/Henjo:_Hen_na_Joshikousei_Amaguri_Chiko
