Wife Is On A Business Trip

My wife and I have an open marriage. Swinging wasn’t a great fit for us. She hates watching me with other women, but she also loves strange cock; however, she’s a mom, afraid that our high school daughter might find out. She feels like it’s hard to hookup with married guys, she prefers married guys. But if they get caught she thinks the wife will drag her into it. she’s concerned about meeting up with weirdo’s .
I know, a lot to deal with. On top of all that, she’s pretty vanilla when it comes to sex. Missionary and doggy and she’s done. Isn’t into sucking cock. All this turned into her dragging me along when she would meet men. Usually online, sometimes from just life. If a guy flirts with her she tells them our deal. A few times it worked out where the husband fucked my wife and I fucked his person.
Like I said my wife is pretty vanilla. When she hooks up without me she calls my phone and lets me listen in. It’s usually very little talking, I can hear the fucking part, but whispers until my wife moans and then the guy gives out a big grunt. I’ve heard guys ask if they can cum on her face, on her tits, in her mouth. She has always said no. She asks them to cum inside her. 98% of the time that means filling up the condom while he fucks her.
This week is different, she’s at a company meeting in Scottsdale with people she doesn’t directly work with. She has fucked two guys this week and possibly a third tonight.
Last night the guy was really vocal, he had my wife sucking his cock. I was very surprised. Keep going and you’re going to make me cum in your mouth he tells her. Already hard listening to them, I pulled my cock out hearing this. She stops, I hear her say something, and he tells her to keep going, I am going to cum in your mouth. The way he said it made my cock throb, I was wondering what my wife was going to say. I want you to fuck me, again, I don’t hear her say things like that much. He tells her he is going to fuck her, after he cums in her mouth.. I was over the top as I heard her start sucking again. After a few minutes he tells her he close, keep doing that. I’m going to cum, I’m cumming in your mouth.. fuck. I was shooting myself.
There was more to come. Bend over. Then I hear her say it’s still too big. She called me after he left and told me he had the largest cock, thickness that she has ever had. He made he cum with a semi-hard on.
