Yes, and I have. I have watched her service two of my friends before with me just as a viewer. And have repeatedly 'tag-teamed' her with a specific friend of mine. Details upon request :);)

Details requested... ;)

Post away :D

We have shared several times
 

We had discussed swapping a few times and she was said she was up for it with another couple only. So we finally meet another couple and swapped partners, in the same room, and then ended up back together for the rest of the night. She was kinda upset the following day, thinking I was going to leave her, etc.. After a long conversation , I finally convinced her it was just sex and I had no desire to play without her and didn't want her playing without me as well.
After that conversation, she has opened up and we have swapped with other couples and had a few MMF three ways. MrsV loves to give head, and let me tell you, the best bj's she's given me are the ones while she's getting pounded from behind by another guy.
We still haven't made the MMMF fantasy come true yet. Dealing with real life issues have taken up most of our spare time lately, but she still wants to be made airtight at least once.
Neither one of us have any cuckhold desires. It is a turn on for me watching her have fun with some one else, but I'm always there and join in whenever I want.

I'm not sure that I could actually go through with it. I will admit though, that the idea of my wife getting fucked by another man is really hot. I'd so love to see her completely exposed to him as she squirms and squeals and cums all over his dick, like she did for so many guys before me.

I could
 

I would let her fuck others in a heartbeat. I would love to see the moment where a strange cock enters her pussy

During one of my friend's bachelor parties, my wife went with us. On the ride back to our hotel my drunk friends felt her up in the back of the car...never really considered it sexual though.

Just this past weekend my wife had a HS reunion. She looked great. She had a few guys checking her out and hugging her. I'm sure they were interested in feeling her up more than they did.

Great thread. Watching my wife do another guy is my biggest fantasy. I doubt it will ever happen, but I've made some progress. She's always been very prissy about sex. Very unfortunate. At first I tried to spice things up by telling sexy stories during intercourse, but she would usually tell me it's gross and I should stop talking and finish. Yep, it sucked.

I caught her off guard once though. I told her some made up tale about us fucking on the beach when a guy came along and started watching. I said something about him taking off his bathing suit and kneeling down beside us. My wife came out with her usual, "Gross, this is stupid..." But I cut her off and said, "He kneeled down beside us and I took his cock into my mouth and started blowing him."

My wife was like, "REALLY??? YOU TOOK HIS COCK INTO YOUR MOUTH???"

I finished the fantasy story and I could tell my wife enjoyed it.

I've brought it up a number of times since, with variations. She fucks him. Then she guides his cock into my ass. Or he fucks her ass and I lick his cock clean. That sort of thing. She has sex with him and I have sex with him. She's never once told me to stop.

Now we are at a point where she will fuck my ass with her finger or vibrator while saying, "You want it don't you. You want a big cock in your ass don't you?"

I say yes and tell her she should find a man she likes and we'll invite him over so he can fuck us both. She heatedly says yes, but I'm sure she's not being fully serious yet. I think if I invited a stranger over anytime soon she'd divorce me. I need to work the situation a little more.

Sometimes gay male stuff really turns a lady on. I was on a cruise recently. One of my lady friends was blowing me when another friend walked up. He had recently told us he was bi. I asked him "Did you find any dicks to suck?"
He said "No.", so I pointed down. Whereupon he bent down and started to share my dick with the lady. She was so turned on! She would stick the head in his mouth while she licked the shaft, then swap positions with him. After a few minutes of this, she absolutely had to have me fuck her.
Maybe we will do a real threesome with him next year.

My ex/fwb got propositioned for a 3 way with 2 guys she banged before. She asked me if she should and I told her I was fine with it but she ended up not wanting to since both guys were in relationships. She said she would do one with me if she finds a guy she comfortable with. I'm pretty intrigued by this but I don't know anyone who would be good or how to start it without being awkward.
