Don't know the whole story behind this (other than "a buddy") or how much other footage there may have been, but having watched several different friends fuck my wife over the years, I can tell you that it's not really uncommon for the friend to not last very long the first time or two (assuming this was their first time). Keep in mind your friend has probably been fantasizing about fucking your wife for most of the time he's known you, so getting to actually do it with your blessing is a big fucking deal. There are nerves, excitement, all of that. Nothing to be ashamed of at all.
I have one particular friend who unloaded in my wife's mouth literally about 30 seconds after she started sucking his dick the first time. And afterwards he even admitted to jerking off before he came over so that exact thing wouldn't happen... but it did. Again, nothing to be ashamed of, and it's actually pretty hot in its own way. And I can tell you for a fact that it's very flattering to the woman to know that she turns a friend on that much that he can't keep from cumming. Anyway, just another point of view from experience.
I'm 50/50 on if I want to see my wife with someone else. Sometimes I think it would be the hottest fucking thing EVER! But, on the other hand, I think if she liked it too much, she'd want it ALL the time and I wouldn't. I'm thinking about offering her a ONE-TIME ONLY thing, since she was a virgin when we met and has never had any one other than me.
muy rica la madura, algo seca al principio...el man buena verga y tremendos huevos...pero al final no duro nada, le largo enseguida la leche...que decepcion
The mature one is very tasty, a bit dry at first... the man has a good cock and tremendous balls... but in the end he didn't last long, he squirted his milk right away... what a disappointment
