Boku to Kanojo no XXX

i thought the summary sounded interesting so i was wondering if anyone knew where to find it

^^ thanx

So far, all I know is that there's only one volume out so far. It's hard to find though. I have the first volume. There was another thread somewhere here that asked about it. Search for "your and my secret" (the english name) and you should be able to find more info about it
