Info about variables...

Suspicion is obviously how aware the people are that you're watching them... Try to keep it low unless you want to get caught. If it's someone you know, maybe you'll get off with a warning or even... A pleasent surprise! That's unlikely though... If that someone is in the changing rooms in public however, you might be finding your way to jail, or at best, a beating...

Horniness is also obviously just how sex-crazed you're feeling. If it gets too high (Over 75), your erection or a wet spot will be showing, causing some... Awkward situations... If it goes over 100, it will be too much to bear, causing you to burst in your pants, possibly drawing attention to you... It also might cause you to do something you might otherwise not, trying to hard and getting caught in the process for instance... The only way to get it to lower is by cumming, so try and get yourself into a good position to do that!
