Is it normal to show up naked on cam with your own brother?

We both like chatting for fun and we have realized about the huge success that we have when we are 2 people on cam: all the girls melts and they undress immediately and they do everything (Everything!) we ask. All the couples gets very excited by being watched by 2 and by seeing us naked or half naked (mostly from nudist sites) ...and again they do everything we ask. Sometimes we talk directly to the guy and we ask to show his wife and show her parts. And then we ask to do this and that. And most of them likes to be directed like robots because this is what they are looking for to relight their flame. And it's amazing for me, since I'm a porno lover, to be able to do that. Amazing.
We chat separately, each one with his own computer with the cameras pointing to both of us. When we log-in to any social-cam-site we are often the most clicked.
We never touch each other and we never let people think that we do it.
My only real anxiety is about the intimacy that we are creating between me and my brother.
Sometimes we are so captured by this game that we we don't realize how many "sexual experiences" we are actually living together. I think that, in my life, I "came" more times with full light sitting next to my brother than I came in my bed. And I'm not sure where this thing is driving us.
I apologize in advanced for my English. I live in Europe where I don't speak English but I've done my best but I'm still afraid that is not totally clear. Thanks for reading and trying to understand my problem. Ciao
