It's definitely not okay to tie up a Japanese girl and lock her in your room, but when she does it herself it's nothing less than a miracle. As a guy though, I'm always suspicious when a girl feeds my fantasy on this level. With tied up Minami-chan the first thing I would watch out for is a ninja popping out of the closet. If Minami is this bad, I'm expecting the worst! What's your favorite type of Japanese girl? The one who makes a fantasy for you, or the one who let's you make the fantasy to her?
