My step-sister...Kozue. I'm a precocious, emotionless, and highly intelligent person (the main character)...Kozue's brother-in-law. A year ago when my girlfriend (Kana) was recently found, my parents remarried and I got my step-sister. Recently, my long-standing feelings have come true and I've finally been able to date my childhood friend Kana... but when my step-sister finds out, he's jealous... My step-sister, who actually likes me, practices sex so that my girlfriend doesn't dislike me after a long time (maybe for me?) I got excited by having sex with my step-sister, so my dick is erect Stay small! ! "It's been a while since I had sex, it might break, explode, or get an erection..." "I'll give you advice on anything," "I'll tell you what to do," "I think it's difficult to explain it with my mouth, so I put it into practice. I'll teach you,'' "The most important thing is to think about the other person carefully," "Shall I kiss you?" "It's exciting to do something like this with Kyodai." It's not intense sex like AV, but sex that women really feel. It's about caressing and thrustling it in a "gentle, slow" way! [8K changes KMPVR] "Produced and written by KM Co., Ltd."
