(only a title, but if you have the source, why not :p)i stumbled across this pearl a few months ago, it was a oneshot, translated in english hentai manga.The story was something like:a guy surprise a classmate in an empty room of the school while she is exploring herself, he then decide to have a little fun with her and tell her he can help her, she's quite the naive type and accept. They don't go very far at first, but the girl keep sending little papernotes to the guy (he's sitting next to her) during lesson to ask him for more help. It ends with the girl sending a paper to the guy to tell him she loves him, or something like that.I've been searching for this for days, please help a poor soul :)
