if I remember correctly, as long as you start the hot tub games at about 70% drunk , finish around 95% , you answer with a drink on all rounds if you can as it unlock some options for a blackmailer task … then keep yourself below 100% after the hot tub scene has endedAs far as I know, you get the most sex scenes (and some of the scenes go farther) when you keep Ashe between 76% and 99% drunk level.
