They can't be surely? I mean, they've done
everything on camera together. I know it's a bit of a porn fantasy for some, but surely three brothers aren't going to repeatedly commit incest with each other for a quick buck?! What would they tell the families? This stuff doesn't stay secret
The porn base central has Rado and Petr's (centre and right in the picture) as David and Filip Masek. Curiously, it doesn't have the real name of Romi (left above), when it's him who looks most like he could be a brother to Petr. I highly doubt Rado is a brother to either and I hope Romi and Petr aren't actually related. They do look crazy alike though, I'm guessing they both auditioned for the studio by chance, their striking likeness was discovered and it was chosen to market them as brothers. I
hope that's what happened!
