A popular Nocturne fantasy with battles and sex!

Shizuku Kujouin, the Kaguya sisters, Megumi Ichikura and Amane Masaki — all of my subordinates are ladies from the most prestigious families in the country! I'm an E-ranked national magician and I was assigned to lead the newly established elite unit of the Suiou Empire's Demon Beast Division. However, I got cursed by a demon beast while protecting the girls; I became aroused and fully erect — I was unable to hold back from having sex with these prestigious young ladies, one after another.

Can I protect the peace of the Suiou Empire with something like this?
