"Jon, SNARF, you've got to ULP help me!" Karyn said all while shoving more and more of that delicious fudge into her mouth.
Jon Madison glanced over Karyn's blubbery form and shook his head.
"Sorry Dump Truck, nothing in the world can help you with your appetite." He then walked away, leaving Karyn to her fudge.
Sarah Macmillan watched as Karyn finished the dessert and then slump over, sobs wracking her body and causing her fat to jiggle uncontrollably. Something in Sarah went out towards the fattest girl in school then and she shifted her own bulk to hug Karyn.
"There, there, it's alright. I know how hard it is not to eat what's in front of you. But we're both large women and there's no changing that."
Biff walked by then, scoffing at the sight of the two obese young women hugging in the cafeteria.
"Why don't you marry each other, you fat lesbos!" Biff taunted.
Reality was still a bit unstable as Biff shouted this and took his words to mean the truth. Karyn and Sarah felt their bodies tingle and their surroundings vanish.
Soon enough they were in a truly enormous bed, suitable for their weight, and naked as the day they were born. Karyn remembered what she used to look like, her old tomboy life, her best friend Jon, but as she looked into Sarah's eyes she remembered being teased for her weight in middle school, Sarah, also quite pudgy by this point, rushing to her aid.
They became best friends.
And eventually, shortly after their freshman year of high school, they started dating. They would spend whole days stuffing each other with junk food, each enamored by the other's hefty body.
One day, a few years after they graduated, Sarah took Karyn out to their favorite buffet and popped the question after they had eaten three full plates.
Karyn said yes.
And now here they were, on their honeymoon, Sarah smiling gently at her wife and laying kiss after kiss on her nude form.
"I love you Karyn," she said softly.
Karyn hugged her tightly then, the two pairs of memories in her head warring for a bit until her past with Sarah one out.
"I love you too Sarah."
And so Karyn Macmillan started to return her newlywed wife's passion as reality returned to normal.
