Whether good or bad, my sister who is soft on her little brother worries about me not being able to study and enthusiastically tutors me at home. 'If you get a perfect score, I'll do anything for you,' she says, so I studied hard... I made her into a reverse bunny slave just for me! At first, she reluctantly did what I said, but when I ordered her to ride my dick and have sex, she bounced her hips and came over and over! She became more and more obedient, serving me with her exposed J-cup tits! During these three days while our parents are away, I indulge in non-stop sex with my perverted bunny sister!
