Like all the way
Girl do you want Kouichi's whole digestive system to be reorganized....
But weren’t they finding a way or something, it’s been so long since I read it
They were working on a way thanks to the elf elder, Rail, but things got messy and they had to come back to the castle. Then came the egg challenge to prove Kouichi's worth as a bride and while he was still training his magic, it was more to learn how to protect himself than to open his hole to take Caius
But we saw Rail getting properly...railed by a titan's dick so Kouichi will be able to soon as well i'm sure!
Wait, they still aren’t able to fck?
