Sometimes a negative vibe is just an act, to get a reaction from us. The complete turn around part way through the session could have been planned to enhance the excitement for the rest of the session.
I had an ATF at the end of my first session with her tell me not to come back, that she did not want to see me again. Something about her body language to me said otherwise. She also said before that she would not give me her phone number.
I came back to see her a week later. She opened the door and looking a little pissed, said, "I told you I never wanted to see you again". This time it sounded convincing. Well a few seconds later see ran towards me, jumped on me and put her tongue down my throat. The rest was just a great session. Oh, she gave me her phone number this time, lol.
Maybe it was something similar with Hosi? No one can read these Korean beauties 100%.
