Phantom and David were in their weekend jogging session for the morning, until they encountered someone who was there as well. With all honesty, it's a curious greeting. And, that someone was surprised of the "assets" they're seeing. X3
So, this was actually sketched out a little while back before I drew Duran The Monkey. I wanted to color this took ease out some stress I kinda have, so yeah. More PhanAvid booty, because why the heck not!
Also, I wouldn't really put it as mature, because it's really nothing sexual, and they're just wearing pretty tight shorts.
