My hubby knows that my fwb is taking my ass tonight. He hasn't even some that himself. I haven't allowed him to. And he's okay with it. He's been fantasizing about it all day.
Long ago my wife had a coworker that befriended her, then befriended me, then super slowly seduced her and I down a cuckolding path. He ended up being her bf while I was more of a third wheel. Oddly for us we loved the journey and the "mind fuck" aspec
