Wow, sounds like your wife just discovered she was into big black dick. Unfortunately whatever you do from now on is not going to erase her experiences with the hung black guy from her mind. To me, it seems like the best thing to do is continue having the big dick guy over, since she enjoys it so much. But only when you are there to play with them and share in her big dick joy. This way it's a shared experience which you can both take pleasure in......her feeling that amazing dick and you seeing her reactions and expressions of pleasure when she is. You stated that you really did get off when you saw her on cam taking that beast. The trick is being involved in her delight. And I'll bet after some time the "newness" of experiencing the big black snake will subside and she will focus more on the man she loves who was able to allow her to experience such feelings and share them with her. Good luck.
That's pretty much what I've been thinking. Thanks.
She's gone out of her way lately to make it quite clear that she loves me above all else and this is just a frolic. I've been getting enormous amounts of attention lately. :wink: She's also made it clear that she's perfectly fine to drop it altogether. I think I need closure on this more than she does.
