My new student, who is a private tutor, is a young lady who lives in a mansion! I thought she was a quiet and serious girl...but she was a super lewd girl who wanted to stimulate her boring life! The forbidden exchange is "I'll study if you have sex!" ? The temptation is so erotic that I get an erection that I can't refuse insertion! From that day onwards, the lessons will escalate in a naughty direction! It felt so good that the thrust couldn't stop and it turned into a female student's wish!
