We are pretty discrete, but we always go out for dinner and drinks with our friend first, and once we arrive, I become the 'third wheel' as in they hold hands, arms around each other etc. so it seems to the public or anyone looking, that my wife is with him and i'm the one tagging along. She always dresses sexy, but with just enough of a slutty look to turn him on ie: leopard print wrap dress, red heels, nails, lips, anklet etc. so he enjoys when guys check her out as well.
He has a few buddies that know he fucks a 'hotwife in front of the hubby every now and again' but they don't know us or what we look like, but he does text them the odd pic of my wife laying on the bed legs open, or sucking his cock with his tatts in the pic, sometime with myself in the background or reflected in the mirror (her face covered) to show her off to them and to prove he isn't bullshitting.
I love it when he does it, with a message like 'this is that slut i'm doing again in front of her hubby' etc. We are actually good friends although they don't know it, so not insulted by his dirty comments towards or about her as they text back like crazy wantingg more info/ pics which is fun.
