[Reducing Mosaic]SNOS-416 I fucked the shit out of my three-years-older, mature and cute tutor sister non-stop in a house with no parents.

During the three days when my parents were away, I was alone with my tutor Airi… Since she's cute and I've always wanted to fuck her, I took advantage of my parents' absence and made a move. She gently accepted it, so we had sex for three straight days? Spring has finally come for me, an otaku who no one in class pays attention to. I can only look at 'Airi' sensei with a dirty mind! 'Want to cross the line with me?' The worse it is, the more I'm into it. We had sex while my parents were away. I gently spread my legs and accepted the pure advances of my student!
