Perhaps there should be a tag for the good old bit of comparing the cock to body size by putting it up against someone's back or belly? I am still pretty new here (forum wise) so I'm sorry if this is on the wrong topic.

Do you mean penis_on_belly or penis_on back + size_difference?
Like post #3633693 and post #2618903?

Well, I suppose it doesn't have to be size_difference, so much as the one character just needs a large penis relative to the other character's body?

Sorta like that I suppose yeah. So I guess it already does exist? Thanks

That's okay. It's often overlooked.
