My little sister Yui is cute and has a serious personality. But she's actually really into dirty stuff? Because we have sex every day, her test scores are just barely passing. If this keeps up, she'll fail the year. Let's stop having sex for two weeks and hit the books hard! Somehow, we managed to pass the tests, and today is finally a rare brother-sister alone time. As soon as we check into the love hotel, we start kissing immediately! Both of us are in max arousal mode and start going at it right away!! Despite it being her ovulation day, we go all out with multiple internal shots!
