The friends Karla and Giovanna have just arrived from the beach but Karla is high and made her friend feel a lot of embarrassment in front of her friends, even going topless. Giovanna says she regrets letting her friend live in her house and will no longer accept that kind of attitude. As Karla is high, she doesn't take her friend seriously, so Giovanna decides to punish her friend with ass so that she will remember that every time she embarrasses her, she will be punished.
