Thanks for translating these! It's always nice to see new chapters, but I'm sure everyone (or almost everyone really) wants you to prioritize yourself and your own life first before any manga translations.
As for these two, I guess some progress is being made, but I wouldn't be shocked if despite all his "I'm a virgin talk" Kazuma and Aqua had already done the deed a few times while they were working and drinking together and sleeping in the stables. They just couldn't remember due to being drunk, and Aqua's liquid purifying trait purifying anything that could've made her pregnant or something.
