A problem child with zero motivation to study. I was getting irritated by his lack of drive, and then he said, 'If you can hold back from coming on me, I'll teach you!' What an overly erotic provocation! Lately, I've been enduring this interference every time while teaching a class! But today, a female student teased me with, 'Make me come, and I'll study!' Finally, the sex battle of [the one who comes first loses] has begun! Enduring the student's amazing techniques, I also counterattack with my hand and dick! As an adult, I have my pride, so I can't lose!
