Wife swap extreme - Pregnant from the other man?

Who would have thought that this invitation to a barbecue would end like this? Well, I certainly didn't. I got into a fight with my husband again because I had to pee and we were already late again. The couple of friends had been waiting for us for a long time and the mood was accordingly. My husband insulted me and said he would be better off with my girlfriend, no wonder with her huge tits. It's just stupid that her husband is also there. Somehow the blokes get the idea of swapping us as if we were a piece of meat. I only got involved because I think my friend's husband is so hot. And suddenly there's full action and it's public! We suck our blokes' cocks really hard and then let them fuck us in the open air. That was a really cool action. But out of sheer lust they squirted in our pussies - oh God, that really wasn't so clever! We should have thought about that beforehand, but that's how it is when you're really horny, isn't it?
