Futa

Now with his basic experiments completed, Mike wanted to see what the app would do if he messed around with it a little bit, leading Mike to press to revert button, turning things back to the previous iteration with Mike pressing the yes button to keeping Sam aware. Mike then pressed the revert button again, carrying them back to their bed, happy that the app had an automatic disguise feature for affected parties. Mike then selected a small radius that limited them to their bedroom, ensuring he wasn't an includable variable in the changes. Mike then changed Mam and Sam again, swapping their ages like just before but watching as reality changed things to conform to this new reality since it also had to create a history with such a small selection. Quickly, Pam wrapped her hands around the growing Mam, grasping her breasts while her dress seemed to gain a bulge, within a moment it became obvious why this was.

Since the app had to use such a small pool of people, it constructed a reality where Sam was Mam's son and Pam was Mam's husband, creating a more exclusive history where Pam became Mam's first and only, always disappointed at the small sizes of other men and thus choosing to abstain or cancel. It was truly massive, pressing through her fat ass cheeks and going up her back like a snake, waking both of them when they were finished as they turned to one another and began fucking, commenting how it felt like they were doing it for the first time again. As for Sam, he also awoke with his new memories of his futa parents, except now he wasn't simply an ignorant kid and now possessed a massive dick like his father's, becoming over come with lust as he fucked Mam from the back, ignoring his past memories and simply enjoying the moment.
