ROYD-173 "Big sister will teach you all sorts of things♪" Whispering sweet nothings and dirty talk in your ear, demanding raw sex, my exclusive home tutor sister Misaki Kanna

Even though my parents are at home, my stepsister creates a situation where we're alone together under the pretense of helping me study. Then, whether it's to motivate me or because she's frustrated, she whispers dirty words in my ear! She reveals her true nature that I couldn't imagine from her appearance and seems to enjoy my reactions as she assaults my entire body! The act escalates gradually, and I cum over and over again! Thanks to this, my grades aren't improving; instead, because of the personal tutor who suddenly appeared for me, it feels like my brain is being sucked out every day!
