Cooper Koch

He does have a really nice dick. It goes very well with his hot body! This is a really hot scene.
It's thrilling to see someone fluffed up significantly for a film or TV role. Having seen his dick in the two other projects, I love comparing the before and after.

The giant, pendulous balls remain the same of course 😁
 
Odds are good that it is a prosthetic
Why do y'all just lie? If it were a prosthetic it'd likely be a cut dick (and we can see he's uncut). Not to mention he wouldn't rub it and touch it because it'd be more noticeable it was fake, since prosthetic dicks tend to be more stiff and don't move like real dicks.
