It happens. You're sitting in the chair getting your hair cut or your beard trimmed or your fade faded, your barber swings you around in his chair and swoosh your knuckles land in his crotch. I've never tried to touch my barber's dick on purpose, but if you've ever sat at a barber chair you've accidently touched a dick. If your barber is straight he'll usually move you away from it after he's noticed but I've had some gay barbers let it linger for a moment.
This video is not one of those moments.
