Vote for next game in comments! Vixen knows how much you want to jerk off to her. But you don't really deserve to do that, do you? You'll be humping instead. Prone humping is where you pull your penis (usually while limp) back between your legs and then hump something: bed, chair, pillow. If you do this, know what you're getting into. Proning can have actual side effects, including erectile dysfunction. One session won't do anything, but just be warned.
