In this movie...

30 minutes in the movie, Nicholas Braun and Hunter Cope are both getting undressed to go have fun in a foam party. The first one to go in front of the camera is Hunter Cope but we only see his butt. Then Nicholas Braun goes, and for a frame we can see his low hanging balls in between his thighs, and then in another frame, we can see his dick which appears to be uncut.
