WAAA-324 — I Made My Sister Into A Reverse Bunny Slave For Three Days...! Julia

For better or worse, my sister is very lenient with her little brother, and worries about my inability to study, so she tutors me diligently. "If you get a perfect score, I'll do anything for you," she says, so I study hard... and she becomes my personal reverse bunny slave! At first, she reluctantly listens to me, but when I straddle her and command her to have sex, she bounces up and down and cums like crazy! She becomes more and more obedient, and serves me with a titjob using her exposed J-cup tits! For the three days while our parents are away, I'm going to have sex with my lewd bunny sister!
