After Patty finds her sister Nicole eating and making a mess with the desserts from her new business, she decides to punish her without her mother finding out.

She takes her by surprise and takes her tied up to the basement where she will make her pay for destroying her dreams of having a new business, so she decides it's time to teach her daring and hungry sister a lesson.

Leaving her in just a bikini (very sexy, by the way), Patty places a bondage ball in Nicole's mouth so her mom can't find out. Patty is also wearing a cute bikini and is very upset, so she applies several cubes of chocolate to Nicole. But Nicole is much stronger than Patty and manages to break free, and that's when the fun begins.

They wrestle with each other, trying to knock each other down in all the sticky, dark chocolate until both girls are completely covered in their bikinis.

Then some pies join in, leaving their faces covered in cream and chocolate, but Mom arrives and punishes them for not obeying her, and they end up even more messed up!
