Husbands who are involved

My wife is fucking her friend, even though it's "behind my back." She did tell me during sex she wanted to watch me suck a guy's cock and get it wet for her. I find the idea exciting, but I'm not sure if it's just because I'm aroused by the control she'd have over me, or if I'm bi without realizing it. But I'm getting hard thinking about it.
I’d fist her and fuck her repeatedly in every hole infront of you
