How to convince her?

My wife is 24. She's 5'4 115lbs with brown hair and blue eyes. Not sure how to bring all of this up to her. She knows that I am bi and says she would enjoy seeing me with a guy. But I would love to see her get taken by a WELL hung bull, that I got to clean up. She is very kinky in bed but says that she isnt sure about being with another guy.Im 7.5" but feel that its not enough for her. I have seen her handle a 9.5" dildo with no problem, and she has been with a guy that was 10". Any advice?

So no one can help????

First approach would be to tell her that it is all about her and not about you. You want her to experience as much pleasure as possible and you would support her in her actions. Remind her how sexy she is and how others feel the same. Remind her how that appeal felt to her before she was married and that still exists. It could be even more exciting for her each time as the anticipation builds allowing her to let out more of her inner sexiness. This is just an idea as others I am sure have other suggestions. Could you share a pic of her. Let us know how it goes.

start by watching porn movies with MFM and get her hot to the idea and perhaps let her fuck a guy on her own without you and after a few more she will see that you are cool about it and then you might find a third

consider this approach...
