Has a stripper ever paid you after FS?

Crazy story. I have been eyeing a girl for weeks at my favorite club and finally got the nerve to ask her for a VIP room. Typically we only did lapdances. In VIP she offered FS for $200 and we spent the next 20 minutes doing every position on the map. I even DATY for a few minutes. We ended the session both drenched in sweat and she told me she hadnt been plowed like that in weeks. Said she was having a rough month and the session brought her back to life. I kissed her and said Id come back the next week to see her again, but the crazy thing was when I pulled out my money she said it was on the house and gave me $10 in singles. My mind has been blown. Im wondering if the sex was that great or she figures she will make the money back from me because I stop by so frequently.
