[KRBK] KR secretly 🍆💦 on BK's pics

after receiving BK's private SC pic, he discovers a hidden secret about his student's personal life that he'd never expect (but he likes it,, he likes it a lot he might add). and whenever the pressures from the higher-ups gets him extra frustrated, he jerks off to his favorite catboy. BK is completely and utterly unaware of this. 

and when BK finally swallows his shame and goes back to class, maybe KR corners him on their break to tell him how much of a good boy he is (of course) for coming back to class. or maybe he gives him his punishment for stepping out of line with that photo... or... both? 😈
