[FJIN-067] A total of 13 shots. My step-sister, who was born when my parents remarried, is a virgin. I was pounded and creampied by my defenseless big-breasted sister, who was sloppy but too erotic... Hoshi Asuna (Censored)

Hoshi Asuna is 25 years old and in her third year of employment. She works hard during the weekdays, but is lazy on the weekends. She's an innocent girl. A girl with a lost cause. A nymphomaniac. My step-sister. She masturbates 10 times a week. She has a very strong libido. Her big breasts are so tiring that she can't help but rest them on the desk or chair. She loves games and anime. And this is in Kansai dialect. When her younger brother comes home depressed after not doing well in his job search, her older sister says, "Your shoulders are stiff, so you're so negative! Here, let me massage your shoulders with my boobs!" Brother: "It has nothing to do with boobs." Sister: "This really works." This is full of over-the-top erotic developments, a little humor, and sloppy misunderstandings.
