Kazuma and I have been close friends since we were young, so I often visit him. Kazuma has a beautiful, kind, and lovely older sister. Yes, she is my first love. Later, due to focusing on studies and attending different schools, I no longer met her. And now, when I am in the same school as her, seeing her again, the emotions in me are still the same as before, she is even more beautiful now. Today, I went to Kazuma's house to retrieve a book I lent him. Since Kazuma was not home, I waited for his sister, Sakura, to help me. After getting the book and about to leave, she suddenly seduced me. My last chance has come! She always thought I was an inexperienced boy. Indeed, I am still inexperienced, but with years of watching adult films, I have accumulated a huge amount of knowledge about sexual matters and applied it to her! Fiercely thrusting my erection into her! Making her climax over and over! Driving her crazy and unforgettable of me!!!
