Every Monday, Wednesday and Friday I walk with my wife the half a mile over to my friends house, a friend I've known since we were eleven. His wife and my wife sit, talk, drink wine and watch soaps.
We on the other hand do some weight training in his home gym, one he's set up in his altered garage. But we rarely get a full hours exercise in. That's because as the girls watch tv and drink wine, I'm usually taking his cock deep up my arsehole.
It's something we've been doing pretty much since we both discovered what our cocks were for. His cock is far larger than mine and thus his role soon became, after we'd been sucking one another's cocks for a while, one of the "Top". He first fucked me in a hay barn on his uncles farm. We'd both just turned fifteen and I couldn't get enough of his cock fucking me after that. Every opportunity we got, we'd be fucking like rabbits and I was becoming a very willing fuck buddy for him.
Girls, football, jobs and marriage slowed us down a little, but we still found time every now and then to fuck. Then by sheer chance two years ago, my wife began working with his and they soon became inseparable friends, just like us (Maybe they don't watch soaps).
We organised the tri weekly get together's last year around mid January, and since then three times a week, and maybe sometimes after we play football on Sundays, I have him fuck my arsehole as often as we can. Watching his massive muscular body fuck me from behind in the floor to ceiling mirror he's had fitted in his altered garage, is so fucking horny, I bust my cog so hard every time he does it.
We sometimes tell each other we should stay faithful to our wives, and sometimes we last about a week without fucking. But then we get together again and his cock and my arsehole just need each other.
