I don't recall her mentioning the trip; it could be that no one asked. Although, she decides what comments to answer and which to ignore. I don't follow her on twitch, and before these recent streams, was only able to watch random streams others posted. But I seem to recall that she either ignored or said outright that she would not talk about her OF work on twitch to keep it more PG.
So I was surprised when in these last streams she acknowledged her OF material and even joked about Mr. Camera San and the things he's seen. She mentioned the recent maid video as one of the characters she is working up. I mean she talked about her childhood car accident where she lost her front teeth, she walked us thru her panty less encounter with her gardener, admitted that she was seriously considering not doing OF, until, thank God, Gwen changed her mind. So what could be so intimate and personal about the Japan trip , that she a known manga/anime fan, isn't gushing about it .
Let's ask her in the next stream.
