28 [M4A] UK - My MIL knows I’m hung and I love it. Finding your in-laws attractive or wanting to chat with a BWC

I’ve known her since I was a teenager. As we both have gotten older I have appreciated her appearance and personality more and more. She is like an older version of my wife so I feel it makes sense why I have some level of attraction to her. Back some years ago while my wife then gf was still living with her mother. I wore XL condoms since regular condoms don’t fit me. My MIL came across the box, used wrappers and even a used condom obviously in the outline of my penis. She never said anything to me but I felt she treated me a little differently after that. I have definitely found out some things about her also. Anyone want to discuss? Especially women around her age? Anyone else have a thing for their inlaws?
