Seima catches a man rummaging into her school bag. She runs to pull the man on the floor. She hurts him with her foot. She keeps him lying on the floor. Then her step-sister Miko comes to give help. Seima sits on the man's face, Miko on his feet. They laugh because the man can't breath under Miko's ass. She stands up and sits again, sticking her pussy on his mouth.
