Lots of the guys here like to talk about how much they like watching their wife get fucked by another man, either in a threesome or swapping, but they like to see it. These guys give two reasons; they like to see their wife enjoying herself, and they like to watch the action themselves...it gets them hot knowing some other guy is doing his wife.
Most of the other time it's the other way around for me. Sure, I like it that my wife is having a good time, we wouldn't do this otherwise, and it is hot watching her in action. For me though, it is way way hotter looking down and thinking, whoa, that's another man's wife that I AM fucking. When I blow my load in her that is what is in my mind, it's another man's wife taking it.
I don't say anything to a wife, but seeing her wedding ring while fucking her gets me hot. The one where I really lost it though was when this couple we swapped with had just got engaged, and she only had an engagement ring. While we were screwing I saw the ring and stated thinking how I was fucking his girl he promised to marry, and although I usually have good control, I blew my load right then, way too early.
Any other guys like this??
