In Episode 8 of Season 1, we get brief nudity from Antoine Cholet and Nicolas Gonzales.
At the beginning of the episode, we get a very hot bath scene with Nicolas Gonzales but without full nudity.
Later in the episode, Antoine Cholet and Nicolas Gonzales are both naked one next to another. We clearly see both butts. We then briefly see Antoine Cholet uncut penis, and as they fight naked we can guess what appears to be Nicolas Gonzales bigger penis.
