I was reading a het-manga a few months ago; had it bookmarked so I could find it. But then I del'd my SYS32 folders and installed Ubuntu to make my internet go faster. My internet(and startup) is a lot faster, but now i can't find the name of the het-manga. About all I can remember:
The main character(a guy) goes off swimming in the ocean. He finds some girl, they have sex, and he thinks it's over. Then it turns out she's a demon who needs to have sex with him for energy, and when she does, she's generally sucked "life energy" from the guy. But for some reason, it doesn't work for him.
That, and there's one scene where everyone in the school is looking for either one or both of them(the boy and girl demon). They eventually start screwing in a locker with a mind-controlled student saying repeatedly "no one is here...". And the girl demon also has a magical hairband.
Any ideas? iirc, it was an original work, and not published.
