Two men who got a taste of sex with a girl who doesn't understand what they're being teased about ambush her on her way home from school or cram school, and lure her into their home with words like "Let's take shelter from the rain" or "I have a fun game for you, let's play together". School swimsuits, pee play. When a girl confesses that she wants to make more friends, they suggest they hang out naked, insert their penis into her tight pussy, and cum inside her!
