During a summer Japan grad course in Tokyo, I had a small (and expensive) student room in the attic of an old house that had the oddest compartments. Also in the attic were a girl, a pretty girl, from Germany, and a Japanese boy from San Francisco -- each with a small room opening onto our shared kitchen/sitting room and giving onto a washroom and a small balcony. The view of the local park and Kanayama Shrine was wonderful but I couldn't escape the sensational views of my pretty fellow lodger. She knew my feelings -- probably better than I did, and she wasn't shy. And the Japanese lodger seemed very nice too.
In sharing the washroom, there was not much modesty: the glass to the shower was frosted but the girl only wrapped a towel around herself when she came out and that had quite a number of shortcomings in terms of what was wrap-able and she was casual in how it was all done up. I wasn't shy either and the boys made a point of wandering around in the heat either nude or nearly nude and she was casual about that too. Toshi was quiet but very warm towards me.
Supposedly we were there to study Japanese religious customs in the Kanayama fertility cult but Suzi Q -- she told me that was her name -- had smiled and said she was doing that the easy way although what that meant wasn't clear and I felt very keen to find out how to do things easily. Then after a week or so, Suzi came back from shopping carrying some packages and was followed by a very special-looking lady. She was Chinese, old --maybe 35 or so, but she had a great figure and not much of it was hidden by her light yellow silk dress. Suzi nodded meaningfully and said this was Jade. She was really graceful with poise and confidence that I rarely see in ladies: I guessed she knew more about men than anyone else in town and she was going to be charming about it.
