"What are you doing?! I'm leaving you behind!" Four female college students came to a hot spring inn in the countryside, screaming and squealing. The son of the inn is staring at them. "Those girls have big boobs..." This boy is actually a very naughty kid! He gets carried away and touches their breasts, peeks into the bathroom pretending to clean, and even has sex with them in the end... But even female college students won't let themselves be fooled! When they are caught, the naughty kid screams with joy as he is punished with a threesome. Don't let your guard down just because they are children. An enviable amount of mischief.
