First of all I have to mention that the communication with the staff is really great, probably the best I've experienced in all of Japan. Since it's a fetish establishment and being a foreigner one could have a lot of questions, but they are very nice and are patiently answering everything, making sure everything will go smoothly.

This time I chose Yuzu since she does some stuff which I always wanted to try out. By the way, it is recommended to read the diaries of the ladies in advance to see what is possible, to make sure you make the best of the time (preperations etc.) and to understand the person you are about to meet. Trust me, it really helps.
That being said, Yuzu is both a sweetheart and a whirlwind full of energy. Once again I was lucky to choose a girl who really enjoys her work! She was also well prepared with a suitcase full of stuff for all your perverted needs out there.
She only speaks japanese with very little english on the side, but you can just make sure to have a translation app ready beforehand (she had one, too). I know very little japanese, but the play went smoothly without it. She will guide you with gestures if necessary, so just let yourself go. She also made me feel very comfortable being in a perverted position with stuff I've never done before, so the session was really fun (and messy)!

Yuzu took care of everything and I had a great experience because of that. Will definitely come back.
