Magical Girl Lyrical Nanoha dj - Nano X Fe!

Nanoha and Fate find a hentai manga that was put in their school bag. They read it together until Fate says to herself, "Two girls doing that.. I wonder if it feels really good?" Of course, Nanoha hears Fate say that and says, "Then why don't we try it ourselves and find out?" You can guess what happens next.
