You had a fun time recently with the principal's spoiled little daughter, so why not giving it another try in the hope of getting lucky again? You know exactly when is the principal away from home, so you'll visit his house to meet his daughter - you'll find a daughter there but it's not the spoiled cutie, it's her strick big sister, Sarah. You have to explain why you're there and also convince her not to tell on you... being the popular handsome guy of the school (and the whole neighborhood) it should not mean a problem to you to get out of trouble, and still get lucky again.
