~New Kawaii of the Adult World~ You, who helped two real angelic sisters, Rin Seo and Karin Kitaoka, get into their first-choice school as their tutor, are taken to a love hotel as a thank you. Messy mucous membrane contact… the devilish girls' seductive violence… 17 endless ejaculations… and while you are completely burnt out, the two sisters share a happy kiss and it ends…? Huh? There may be an extra 'reward' waiting for those who watch this work to the very end. Rin, Karin. You are princesses.
