I personally am curious as well. Most semi-legit places have 9pm last appointments, both of my regulars had stayed late for me before (like 30min to an hour late). A couple of semi-legit places have girls who stay there overnight, you may be able to get lucky if one of them happens to be staying that night. Beyond that, I think you may be stuck with a bodyrub place or a Leolist gal like Nova or MollyMoore. I have had good experiences with both Nova and MollyMoore for late night massages.
