[ENGLISH-SUBTITLE] SW-507 My sister's friend invites me with a panchira pretending to go to my house or study. I don't know if it's a mischievous heart or serious, but I have to teach you various things with a bottle erection

During the summer vacation, my sister's friend came and had a study session at home while my parents were away. Girls who are curious about H intentionally show off their panchira to my brother's servant and enjoy the reaction. I want my sister to come secretly while I'm away and ask my Ji-Po to teach me various things. Ji Po immediately responded to the temptation of girls who are too cute and too erotic, stealing everyone's eyes and fucking with everyone.
