After the news, David fell into a deep depression. His body was an official prison sentence. He hadn't committed any crime, he had been kind and thoughtful his whole life, and yet society colluded against him to punish him, to give the worst punishment imaginable: trapping him in an obese girl's body forever. He cried constantly now.
"I'd rather be in a regular guy's body in an actual prison forever than be 'free' and trapped in this body," he told Mariah. "Freedom is worthless if I can't escape this body. This is the worse fate imaginable for anybody. I wouldn't wish this on my worst enemy. I wouldn't be cruel enough to sentence anybody to this fate. No one deserves this." He started crying.
Unfortunately for David, it actually COULD get worse, and indeed it did. His body had a rare genetic defect causing gigantomastia—Mariah wasn't merely fat, her body was dedicated to producing extra breast tissue. David felt the extra weight and sensitivity with each period, and after a few months he would have to buy a new bra. Then a few months later, another new bra. It became clear to David that the rest of his life would not just be about navigating "womanhood"... He would have to manage his breasts, hour by hour, for the rest of his life. He'd even lose sleep, feeling the discomfort of his huge breasts weighing him down and smothering him, then getting sore as he lay on his side. He felt less like a person, and more like a pair of breasts with a brain attached. It was all about moving the breasts around, trying to keep his body as comfortable as possible until the next time the breasts had to be shifted.
Meanwhile, every person he met would stare daggers directly at his breasts, not even hiding their reactions. Men and women, equally, would cruelly reduce him to a pair of breasts, and he could feel their judgment of him for having them. He couldn't express how badly he wanted to have them surgically removed, to destroy them. Others just assumed he loved being a big-tittied bitch and maybe even got implants. He teared up just thinking about it. Implants?! He used to be a teenage boy, with a flat chest and no breasts at all. How badly he wanted to go back to that time.
One month later, he could feel his new bra biting a little into his breasts. Surely, they couldn't be getting.... even bigger? "No," he wept to himself, "No, God, no! I just bought two new bras! No! Even bigger? It's not fair!" He started crying hysterically. "No, no!! They can't keep getting bigger!! It's not fair!!"
