Sounds like a lot of fun. Just older? Or would younger and in full bike leathers be the 'bit of rough' you seek? I could certainly provide that.
And on what is it you seek? Just their company? To be looked at and fetishised? Or more?
I've been trying to play with a couple like that for a while. Mine definitely doesn't know about that side. Last night, I had a sub on the line, doing everything I said, and sending me photos that I could use to 'blackmail' them with. Fun.
