Not everything has to be narrated. It’s ok to simply say what happens, without having to stick to 100% realism, narrating every small interaction. You (probably) don’t narrate your PC’s going to the bathroom either. In my experience, your players won’t mind, they want stuff to happen too! It is a tabletop role-playing GAME after all. It’s not meant to be a 1-to-1 representation of what life would be like in this fantasy universe.
