6 - Out of Control - Terry and Marlin come to a resolution about the nature of their relationship and the special extraordinary circumstances that make it open and somewhat... fluid. Even still, Terry is having doubts believing that he brings anything special to the table beyond what his fantastic girlfriend is currently experiencing and rumored to be ultimately capable of. So he does what anyone in his shoes would do... find ways to prove that he can spur on the fantastic growth capabilities of both Marlin and Diane's super macromastia. But will it start and end with just the three of them?
7 - What If - Terry faces what his future with Marlin could be and discovers that many physical, mental and societal obstacles lie ahead. Marlin shares something new about her condition, making Terry worry even more about her ability to cope with her growing issues. The two explore their intimate and deep-rooted bond and realize that they have more power over each other to manifest their desires than they ever thought possible causing Marlin to make a significant breakthrough.
8 - Collateral Damage - Marlin's recent growth spurt gives her great insight into what's ahead for her. She comes up with a "Booby List" of things she would like to do before she becomes too big to do or enjoy them. The list is long and eclectic which causes confusion and stress for Terry. It quickly becomes apparent that he needs help to fulfill her wishes and Lina is brought in to mark one of the most important entries off the list. But will Marlin be willing to receive her help or will her wild mood swings and possessive behavior cause all of them pain and discomfort along the way?
9 - Expanding the Portfolio - Terry is worried about Lina's whereabouts and in the meantime tries to keep himself occupied by categorizing Marlin's size as she has moved well beyond any traditional measuring system. Diane plays coy with her actions and her motivations even though Marlin continues to impress with her abilities and rate of growth. Terry finally catches up with Lina in an unexpected way with help from someone else.
10 - Record Breaker - Terry finds himself between two very seductive and beautiful women who want more of what he has to offer in pushing their bodies to even higher levels of voluptuous curves.
