PES-112 Sister masturbates! Brother gets an erection and touches her to give her a sex education! 2 disc set

My little sister comes into my room without permission and masturbates alone while looking at my PC, pornographic DVDs, magazines, etc. I knew about it but I turned a blind eye to it. But I can't stand it anymore. I'm going to show my precocious little sister a real dick and give her a sex education. I entered my room while my little sister was masturbating and asked her, "What are you doing?" She stammered, "My friend did something naughty with her boyfriend. I was interested too..." So I ended up giving her a real sex education... [Please note that there may be some disturbances in the image and sound, but this is not a defect in the product itself]
