Hello! I'm Dali, illustrator and comic artist π
I've seen this in a few furry pieces. What are the bulges on the side of the cock? They look kind of hot. Like a "ridged for their pleasure" kind of thing.
It's a 'knot', I believe it's meant to keep the cock inside for insemination. They're found on canid cocks but I see them added to every type of furry design xD
