I was faced with this situation with an SP I had met a year and a half or so ago. I had been communicating with her about setting up a session a few weeks down the road, and during this communication, we decided to meet at a bar one night (a bar she likes to regularly go to). She had been out with friends earlier and when she showed up to meet me, she was already feeling no pain. We hung out for a while and she had a several more when she suggests we go back to her place. My inclination was a working girl isn't trying to pick me up, especially when a couple weeks later, I was going to be paying her anyway. So I replied "Sure, I can give you a ride home". So we pull up in front of her building and I thank her for a great evening. She looks at me like I'm an idiot (which to clarify, I have never denied that I was lol), and asks if I'm going to park and come inside. Well, okay if you insist. In we go, and as soon as we walk inside, she plants a big deep passionate kiss on me, then goes and grabs a bottle of wine. We plop down on the couch, we make out a bit, and she drinks a couple glasses of wine. (I don't drink, btw so I'm stone cold sober).
Finally she suggests we go to bed. I was still pretty new to the hobby at this point, maybe 5 or 6 months and 5 or 6 ladies into it, and honestly, I still wasn't sure there wasn't going to be anything said about money at some point in this lol. But aside from that, she was quite drunk, and I wasn't, and I'm not a kid, and this was a girl who I had only met briefly a couple months earlier at an industry party. No doubt, I wanted to go have sex with her right then, but I also knew right from wrong, and she wasn't in a condition to consent. And the thought of her crying rape later did cross my mind. Anyway, I somehow managed to avoid the going to bed suggestion, we hung out a bit and I could tell she was ready to go to sleep. I wished her a good night and left, still slightly kicking myself lol. The next day I texted her and thanked her for a great evening and that I looked forward to our session a couple weeks later. She replied by apologizing for getting drunk, and thanked me for not taking advantage.
