Amateur who took "a party game popular in the city" seriously and got their erotic switch turned on. A simple girl from the countryside blushes and gets embarrassed when kissing through a plastic wrap, and sways her hips erotically and cums on her own when cunnilingus is performed through a plastic wrap. When she notices a stiff penis, she smiles at the thought of being fucked. This is how they become city girls and become naughty.
