What Next.

My wife and I have the most dirtiest conversations while having sex just to build up lust in the bed room. We are from RSA my wife and I are Indian she's hot sexy body small boobs big round ass and me with a big 9" cock which I keep telling her my cock is, big as the African men here and this sends her to the moon and back I really don't know what about it makes her so horny and hot but she does. And she witnessed something she never thought she'd ever see she saw a street guy wipe out his cock and take a piss. Now while having sex she explained to me what had happened and what she experienced and she's been coming so hard and is always horny she said she saw his big BBC and she admits it was bigger then mine and am not and am not a big size I really don't know what to do from here. I don't know what to talk about while having sex or what's the next step. As anyone been thru this with their lover's as any Indian men given up their Indian wives how was it? As anyone else given up their wives to this? I really don't know what to do
