I ended up tutoring a serious but extremely slutty delinquent girl. After teaching her a little, she came back with good test scores and said, "let's have sex, sensei" as a thank you! I managed to resist the temptation, saying, "dangerous dangerous! you're trying to get me fired because you don't want to study, right? i won't fall for that!" but she insisted, "that's not what i mean, i can only repay you this way."
