WAAA-543 I turned my sister into a reverse bunny slave for three days…! Rin of the Suzuki family

Whether good or bad, my sister who dotes on her little brother worries about me not being able to study and enthusiastically tutors me. 'If you get a perfect score, I'll do anything for you,' she says, so I studied hard... and made her into a reverse bunny slave just for me! She reluctantly started serving me with an unwilling attitude, but when ordered to have sex while straddling my cock, she bounced her hips and came over and over! Gradually becoming more obedient, her face melting in ecstasy... she actively performs blowjobs and paizuri too! Trained to my liking! With both parents away for these three days, I can fuck the sister bunny hole as many times as I want!
