I can think of 2 cases. One, which I already wrote about, was the phone girl / mamasan for legendary Ami, who was a Baruch student, I dated her, and a few years later, I had a session with her without even realizing it was the phone girl and my former date. Fantastic.
Second case was when I took 2 friends to Unicorn. I was with Lisa/Love and my friend was with Rachel (very thin girl who used to be the assistant to the Dean of Yonsei University). My friend can be quite obnoxious and I knew I made a mistake taking him when I hear a ruckus and it turns out Rachel was so annoyed with my friend that she walked out on him.
My friend, being the difficult jerk that he was, insisted on his full hour and being finished, so the Mamasan who was a retired ho, rolled up her sleeves and dived back in and sucked, jerked, and fucked him until his time was up, right down to the second. After which he didn't even tip her.
A week later, I went again and had an incredible session with Pepsi and afterwards apologized to the mamasan about my idiot friend and we got to talking and it really turned me on that she had to endure this jerk, so I asked if she would consider doing a session with me so we went right in and had a fantastic time together, me pretending to be my friend and the mamasan pretending to be disgusted and whining and bitching about having to fuck and blow me. Miss the good old days when there was a sense of community and all the shenanigans that go with it
