When Luke needs swimming lessons, the lovely Jenna eagerly volunteers to teach him. All their friends can tell where this is going, as they saw the glances Jenna has been sending him for the past few weeks... except for the oblivious Luke. Jenna's unlikely idea is to shrink Luke down to teach him in the privacy of her bathtub, seducing him in the meantime. Will Luke finally snap out of his cluelessness and swim to the gigantic girl's heart? Or will he sink to the bottom of her bathtub?
