The previous reviews paint an accurate picture of Yumi.
She is very beautiful and young. She has a very pretty face, smooth soft skin, tight slender body, perfect natural breasts, and very long slender legs. Very much a dancer's body. I shared several of my preferences before we started and she shared several of hers (light and gentle with breasts and when going down on her, but likes doggystyle hard). She definitely made an effort to fulfill the preferences I shared.
As the other reviews mentioned, she is a warm person but fairly shy and very passive at first. The kissing was very light FK rather than DFK/GFE and it clear she wanted it to be minimal, and wasn't very responsive at first to a few other things I tried (e.g., just gentle stroking). I was worried at first about whether she felt comfortable. Other reviews didn't comment on the kissing so I don't know if that is unique to me (to be fair I am more than 2X her age).
***BUT***, things went much more smoothly once I went down on her, she was much more relaxed, and from there things were hot. She was grinding her hips, responsive, and then from there very happy to go down on me, 69, facesitting, etc.
The true highlight was doggystyle. She looked so hot in doggystyle and was into hard doggystyle that I came in just a few minutes.
She asked if I wanted to take a shower and when I came back she had put her clothes back on so there wasn't the usual initiating cuddling/afterplay you might expect at 400 escort experience. So in total I was only there for about 30 of the 60 booked minutes whereas I would usually stay the full time. BUT, I chalk that up more to her being young and inexperienced rather than rushing/not warm. Before I left, I started a conversation with her and she was very warm, funny, laughing, it was very relaxed.
***TLDR: She is very beautiful, incredible sexy body, warm and kind personality, and natural, and open to fulfilling preferences. My guess is she hasn't done much escorting, she doesn't have a routine, and is shy at first. If you are comfortable taking the lead, sharing preferences explicitly, and okay with light FK in exchange for very young, very beautiful, and hot doggystyle with girl open to fulfilling preferences, then I recommend. I think I might have spent more time chatting with her in beginning knowing what I know now.***
Side note: her flat was very nice. There is a review below talking about an open window and lack of privacy, but that wasn't the case, or she has a new flat now.
