Big Promotion Promise

My wife has been owned by her boss since way before we met and they were very straightforward and honest about how they would continue their relationship regardless.
In essence, she would be my wife but she would remain his cumslut and fuck toy.
It may be difficult for most folks to understand but she has always had a slutty streak and he's made her into his personal assistant and corporate whore.
He's told us that she's accompanying him on a 3 day overnight business trip next week and he's expecting to sign some major deals.
When he dropped my wife off at home last night he told me there was a very good possibility that my wife would be earning herself another promotion and a good sized pay raise if these deals come to pass.
He also said with a good dose of mockery that "Your wife will be sucking a lot of cock but it will all be worth it. Besides, you and I both know she can never get enough cock."
Embarrassing and true.
My dick does throb a little whenever he talks about my wife like that and when I kiss her I think about all the cock that's been in her mouth and I'm so lucky to have such a hot and nasty woman for my wife.
She has told me in confidence that sometimes in the heat of passion he's said he would like to have her wank him into my mouth so he will own both of us. He hasn't said or done anything yet and I think it was just dirty talk when he was randy.
I never had any gay feelings but I have fantasized about sucking his dick and tasting my wife on his meat stick. She tells me it's about seven inches and very thick.
