>>7916Author here. You're welcome! I'm very happy to everyone who seems to have gotten enjoyment out of these stories.
As I've mentioned before: in addition to being weight gain stories, slob stories, and homoerotic stories, I've always envisioned these stories as functioning as a "Bad End" for Shinji, versus where he ends up in the canon of NGE. Both the show, EoE, and the Rebuilds all end with him getting over his limitations, accepting that he has to move forward, and striding into the future to actualize his potential.
So I thought it would be fun to write a progression of stories where, instead of moving forward, he sinks deeper and deeper into oblivion. Fatter and fatter, more and more helpess, more and more no longer capable of making decisions for himself or attaining self-actualization. Him losing control of his bowels, and eventually his bladder, was part of that. I like combining weight gain with bodily functions as a general rule, but here it serves the dual purpose of totally stripping Shinji of his ability to be independent. Swathing him in the diapers was symbolic: he's regressed into an infantile state, the total opposite of where Anno says he's supposed to go.
So in addition to weight gain, slob, and queer eroticism, I also see these stories as indulging in the corruption fetish, which is another subfetish that I like to combine with weight gain. This is a version of Shinji that has failed to learn the lessons and make the progress that he makes in the show, EoE, and the Rebuilds. Instead, he's been seduced by the easy affection Kaworu offers, and is not strong enough to break away from it.
It's Shinji in a diminished, failed state, and on a certain level every other Eva character that shows up knows it. Ritsuko loves it, because Ritsuko's rather corrupt herself; but Rei, Asuka, and Mari are all disgusted by him, not just because he's fat, not just because he's smelly and gross, but because they can all tell that he's a failure.
It was particularly important to me for Mari to show up in the very last story, because of the role she plays in the Rebuilds, especially at the end of 3.0 + 1.0, where she helps Shinji free himself from the "curse of Eva" once and for all. Here, Shinji is so far gone, so sunken into pleasure and affection, that she can't even meet him face to face. We know she likes to smell people, so I wanted her to smell the two scents that typify this corrupted Shinij: semen and feces.
I wanted her to show up specifically so she could be disgusted by the smell, then turn around and leave. By leaving, she's essentially cut off Shinji's last possible avenue of escape. He's fully Kaworu's fattened pet now, until the end of time. It's an incredibly bad Bad End, the more I think about it. But that's pretty hot, isn't it?
Anyway, thanks for reading, and I'm glad you all have enjoyed.
