Three girls attending an all-girls school are hungry for men.They are having fun talking about masturbation, just like male students.Shiori has a younger brother, right?Tei is so excited that she wants to see her younger brother's cock that he asks her to be a model for her art homework, so when he makes her strip naked, he finds out that his dick is surprisingly big!!My horniness escalated and I was made into a toy for my older sister's friends to insert and cum inside me... "Huh? Sister??" After the two of them left, the horny older sister also attacked me!??
