That's cool. I mean yes, it's kinky. But, you both already decided to give the Hotwife / Cuckold lifestyle a try. You as should get the whole experience. As a Alpha BWC I counseled many couples on this. I seem to mesh well with couples young and old that are trying it for the first time.
But, I try to make them friends first. It makes everyone more comfortable. So, before anything happens. We already know each other well. They both know each of our roles. And the wife's husband is the cuckold. Who is not Domanant. Some call them Beta's. His role is to submit to the Alpha or Bull. And it doesn't make you gay.
When I watch a couple give each other deep kisses during everything we do together. I think it's a beautiful caring and loving act.
I will send you an invite to chat privately. Message me anytime. I'm trying to make new friends.
