Sirius:
he likes sports that make you sweat. He like hard core sports. Maybe muggle basket ball and maybe football. He likes to move alot so he loves sports that gives alot of energy. He like swimming too.. he often brings remus for a swim then theyll eventually make out in the swimming pool bathroom.
But one time he would go for wild sports. Maybe rock climbing in a cliff in asia with moony casually sitting and reading at the top. He would scuba dive in the ocean and when he jumps out of the water, remus would go red and hide his face under the towels.
Oh did i mention sirius loves surfing too ? He love aquatic sports cuz he would have a reason to wash his hair over and over again. And he also loves it when remus would blush because his hair would be damp and his body would be covered in sea water and a bit of sand.
Remus:
Remus loves tennis and badminton. And he would argue with sirius because siri said that tennis and badminton is the same thing. He would play for hours with his muggle tennis club. He enjoys table tennis ("MOONY Table tennis is tennis too why would you do the same thinggg ?!?!?")
When remus plays table tennis padfoot would come and play with him (by catching the ball with his paws or snout)
He also loves too play basket ball tho that sport is not his first choice. He likes wiping sweat of sirius so remus is basically a soccer mom who would cheer for his son and fight the referee.
