WAAA-543-UNCENSORED-LEAK [UNCENSORED-LEAK] WAAA-543 I made my sister into a reverse bunny slave for three days!

Synopsis

For better or worse, my sister is sweet on 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 I made her my personal reverse bunny slave! She starts servicing me with a reluctant attitude, but when I order her to have sex with me, she starts bouncing up and down and cumming like crazy! She gradually becomes obedient and her face melts... and she's proactive with blowjobs and titjobs! I've trained her to my liking! For the past three days while my parents are away, I can do whatever I want with my big sister bunny masturbator, cumming inside her as many times as I want!
