This one was an interesting challenge.
 
My guard ponies, Glimmershine and Hunter, relaxing for a sweat in the sauna after a hard day’s work. Yes, unisex sauna. I figured if the Wonderbolts can have unisex lockerrooms and shared showers, then why not same for the guards. Granted I drew this in anthro and feral, but my argument still stands. Ponies ain’t all as uncomfortable about casual nudity if not done a big thing out of it.
 
Hunter is sweating up a storm. He’s from a colder environment with a thick cost, so putting himself in a sauna shouldn’t be for too long unless he wants to overheat. Although Glimmershine is technical from the tundra, the Crystal Empire is a controlled environment with a nice, warm weather. And she’s used to sweating in her workouts much more than Hunter. She usually lasts much longer in the sauna than he does.
 
Hunter is muscular too, it’s just anypony can easily look pretty puny when sitting next to Glimmershine. Just how things are. Not helped when sweating so much one looks like a drowned cat.
 
Could probably done better with perspective and details if I gave myself more time with this, but still like how it turned out.
 
Enjoy!
