The gorgeous busty girl who was once the target of "Molestation OK Girl 5" is once again attacked by a molester. On the bus during her commute and at work, the molester attacks her without asking any questions, squeezing her breasts and relentlessly playing with her pussy. Although Kokoro doesn't want to, her body is in a state of OK. Unable to control her aroused body, she ends up having sex naked on the train... She even allows a creampie, a first in the "Molestation OK Girl" series.
