The guard is good - he encourages himself with a sweet reward. The one he catches is the one he gets. The thief wasn't in trouble either - she was exonerated. And all chicks should be able to suck dicks - the main thing is to motivate them properly. You also need to improve your professional skills. Otherwise you will always provide sex services for free.
The blonde was good at it. She sucked her teacher's big dick (and jumped on it), and got extra credit for it! That's the desire for knowledge.
