I must have done something wrong

I went on a Saturday night. Parking was $20 and entry was $30. I get there and sit down at the benches to the left, and a super hot black girl sits on my lap and asks me how I like the place. I tell her I'm just getting acquainted, as I had just walked in. She told me I was in the right place and that she could give me the 'grand tour'. She said 2 dances was 20 dollars and I agreed.

This girl was absolutely smoking hot, and I'm typically not into black girls. She was a great dancer as well. About halfway through the first dance, she leans back and tells me we should get VIP where she can get some privacy with me and give me a little extra. I ask her how much and she says $350. I told her I didnt have that to spend and so I couldnt do it. She asked how much I could spend and I said $200. She said that with 200 she would give me 30 minutes on the private couches behind us. She said that it was at least more private than where we were. I asked her what that would entail and she said 'just use your imagination'.

I agree and we went around to the private couches where it was knee to knee and it seriously looked like people were fucking. I started getting excited. I paid her the 200 and she just went to town grinding and rubbing her body all over me. Her hand just faintly drifted over my dick and she pulled her garment to the side exposing her pussy and began lowering it toward my crotch. I unzipped my pants and she looked at me with a slightly disappointed face and said 'You cant touch your dick, sorry.' She then seemed extremely uninterested in the dance, even getting on her phone at one point.
