I wouldn't say she was ugly... the face was just "ok." The body was rockin', but the face was "ok." That is why, even if she was not a slvt, I would not consider her for an LTR.
Anyhow, I forgot to put this in before, and am adding it in case any of you find it helpful in your own sarging.
I sorta debriefed her on the ride back, and asked her why she chose to "hang out" with me. She said lots of guys hit on her (direct stuff; she said a guy on a bus once asked her to come join him in the back seat of the bus) and when I sat down next to her she thought, "Oh, here we go..." but when I started talking to her and made it a "normal" conversation she felt "comfortable."
Those were her words.. normal conversation and comfortable.
So I guess the slvt didn't want to be treated like a slvt on the approach, and since I sarged her the way I would anyone (with the exception of fast escalation because it was so clear she was receptive to it) she decided to do it.
