Edeleth and Hot Springs (Patreon)

I have no excuse for the rubber ducky other than I think maybe Byleth would take her baths with one. Also, Edelgard deserves a vacation to soak around in hot water after her Emperor duties.

This is under the "keeping warm" theme. 

Interestingly, it seems Edelgard can withstand heat longer, if we're going by the Sauna activity results at least.
