I want to talk about this doujin again: https://exhentai.org/g/844218/1fa372cf78/
Discuss mecha/powerarmor concepts where sex is a key factor in their operation. General Biological Mecha discussion is welcome too.

Still miffed Z-ton made this oneshot and then forgot about it. It's such a concept ripe for exploring. 150 page continuation never ever.
I made myself a humorous greentext about the concept and shitposted about it in a Symphogear thread once. If this thread gets interest and the mods don't delete the thread I'll post it again.
