Brother Sex

Hi,
I’m a 54 year marked straight male. Ive always been a ladies man and never been without lots of extra fun. Recently I’ve had a craving to try cock, so looked at going to a gay sauna etc.
I mentioned this to my brother, who is gay. He said I’ve always wanted to suck your cock, let me be the first man to do it. Wow what a thought, I’ve always liked i****t, and loved looking at my mum when i was younger, (caught her twice being fucked and watched her, by thats another story.)
Since my brother has said that, we both cant stop thinking about it, swapped pictures etc, its such a horny turn on. My brother wants me to fuck his arse as well, and I think i want him to fuck mine as well. We have planned a hotel room to do it.
What do you guys think?
M
