Friends Wife

So recently my friends wife and i had a steamy make out session one drunken night. Afterwards we talked about our desires to have sex with eachother but how our spouses would feel about the same thing. We got very horny and held our urges to go at it as i was hard and she was wet we discussed what it may be like to **** eachother. Now my wife and her have had a lesbian night once before as well and the other night the two of them discussed the possibility of swapping partners. As the other wife n I are perfect and probably would have hooked up before our marriages we look to discuss these urges with her husband as the final approval I cant stop thinking of how she could suck me or how her ***** feels. Her and I have the tension between us when we hang out and just wonder how to bring it to life and live our passions, but being so good of friends how do we go about the whole swing now.
