[UNCENSORED-LEAK] ZUKO-096 Making playren because the super Katabuzu family is too seriously erotic

You have come to Tokyo to take the entrance examination. I'm staying at a relative's house, which I'm not good at. The reason I'm not good at it is because the four sisters here are not odd and "serious". It's hard to know that you're taking the exam, and of course they'll work hard to start "wrong" cheering for you. If it's cold, warm it up naked, come to the bath to wash your body, and collect all the sperm for concentration.
