Wannabe Canadian Cuck 🇨🇦!

I’m 51 and wife is 50 both white, European background living in the Toronto area, for the past 2 years that I have the desire to be a Cuck, wife gave me some hints in the past, I have asked her 4 months ago if she would like to be with other men and she always says no… we’ve been together for 25 years and I know her very well, I believe she’s might feel ashamed of telling me that she really wants it. I’m building the courage and ask her, what would she think about having someone to come to the house to give her a massage, she loves being massaged, maybe that breaks the ice and she opens up. I know this is not just about me and she needs to want it to.
I can’t play for to long, maybe 10 minutes and I cum fast, she gets frustrated at me because she wants to keep going and I can’t give that to her, she needs a guy that has good stamina and can fuck her properly. I just want to see her happy.
Would be nice to get some input from other bulls or cucks. I’m bi and like to be submissive but she doesn’t know that.
Please don’t ask me for her pictures, she’s not into the lifestyle and I won’t send any.
She’s 50, brown hair and eyes, 5’5, 154 lbs, 34 C breasts, nice clit with big pussy lips, trimmed pubic hair.
