Geoffrey Couët, François Nambot and Bastien Gabriel in Paris 05:59: Théo & Hugo (2016)
The first 20 minutes of the movie are hot unsimulated gay sex scenes, filmed at Paris's gay nudist club l'Impact.
4 minutes in the movie, we see François Nambot's erect cut dick. Then we see his butt. 6 minutes in the movie, we see the uncut dick and balls Bastien Gabriel, and again more clearly some seconds after as he is getting ready to fuck him. François Nambot's dick is fully erect.
