Fucking YOUR wife
You asked how we fellows would feel about fucking your wife. I can definitely tell you that I would enjoy fucking her, while you watched, if that was possible.
Even though we have not seen her totally naked, I am sure she has big hard nipples and a very hairy pussy. I can imagine her stripping naked, then leaning back and spreading her legs to show that "most intimate" part of her body, to me and any other guys who might be there to look.
For the record, Chris, I have been where you are now. I have shown my wife naked to other men, and have heard their comments about her big titties and all the hair on her pussy! What you are doing is completely normal! Any husband worth his balls would be glad to show his own wife's naked body to as many other guys as wanted to look at her!
Get her to show us her tits! Have her show us her pussy! We want to see her NAKED!!
