It's not netorare, at least not meant to be one - it's a tournament of some kind, with female-male teams of two - and females have to make males cum, and males have to make female cum - THIS NEED TRANSLATING! I SENSE MUCH LULZ FROM DIS ONE! :D
Sex wrestling!? What will Japan think of next? In all seriousness, wonderful hentai manga. Like the previous commenter, I would love to see this translated just to know what it's about. Between the blue-haired, tan girl and the cute and sexy redhead with the long mane, I'm not sure which chick I like more.
