When little Ruby Pinch first used her sleeping younger sister to have a little "fun," she told herself that it was a one-time thing. Now, each time Ruby sneaks over to her sister's bedroom, she leaves her with a squishy, bloated belly and a silent promise not to need to come back the next night.

When Berry Punch finds out what her daughter has been doing and forbids it, will Ruby find a way to curb her dependence on Pina Colada's fillyhood? Or will she continue to use her to get herself off, even right under her mother's nose?
