Hey there sweetie! Fap Queen is a kinky JOI (jerk off instruction) game, where you have to follow the Queen's tasks in real life (and sometimes her assistant's instructions... who might be a bit meaner). If you endure their tease and torment long enough, you'll get a reward in the end *wink wink* Just avoid asking them too early, as you might get... less desirable outcomes.
Obviously the game has no real way to check whether you actually complete the tasks, so you can cheat if you really want. But why would you? Following the instructions is the point of a JOI, dear!
Friendly tip: set that Steam Account to private before downloading :D Have fun, sweetie!
