A couple of years back, after a few drinks, a good friend and I got chatting about our wives- what they looked like naked, what they were like in bed etc. We admited that we each found the other's wife attractive. I'd actually, accidentally spotted his wife- Mags, naked before. She was a gorgeous, natural blonde with a nice fair bush and big, swingy tits. And he was fascinated to hear about my wife, Tracy's dark, hairy pussy. It was obvious that I was horny with this heated chat and I was fidgeting away, so he told me to go ahead and have a wank. I was shocked at first but did it anyway, right in front of him. I pulled my cock out and wanked until I came. Then he got his out and joined in. I couldn't believe how big his cock was, it really turned me on to watch him wank it whilst he continued to ask about Tracey's Tits and pussy. Soon, he was pumping out a nice load of cum. That was our 'first time' and since then we have met up for an occasional mutual wanking session whenever we can.
