I had a very similar experience with Vivian a couple days before you.
Fully agree with your review and observations. Its all there in your review, and I'm guessing thick and B is not for everyone.
For me, like for you, being a nice guy def paid off as it made her responsive, eager and Hot. I sure was happy.
Sounds like you romanced her and if was reciprocated.
I might let you date my sister
