HOMA-093 I tutor her younger sister (innocent type J○), but in reality, she's a sex maniac and silently screws her boyfriend behind her back. Silent reverse NTR Yuisei Yui

Film Introduction

I was asked to be her younger sister's tutor. I'm not bragging, but I easily got into a national university, so I was happy to be relied on and accepted the request. I thought she was a clean and serious type, but I fell into this cute bitch's trap! Suddenly doing something like that, there's no way I could look away, right?! In an instant, I was drained of all strength, and I ended up enjoying both sisters.
