My Thick Mother In Law

I have no desire to have wanted to fuck my mother in law! But I ain't gonna lie for a mature women she's thick and am all for thickness, she has wide hips with a big round ass she's old school so her ass is never exposed, while fucking my wife since she's the only daughter from her mum, my wife while banging the lights outa her, says she has hips and a big ass because of the gens off her mother and the way her body is shaped. So anyway my mother in law comes to visit and ended up staying over without thinking to much she decided to shower and that night I got to fuck my wife asking her about more info about her mom's body. Few days after my mother has left, I was looking for something in the kids room and boom the biggest yellow panties I've seen, this definitely isn't my wife's it's her mother's a women that had this underwear on for almost 18 hours before removing them now it was washed but the fact that I got to see the size of her panties to know the size of her butt area is so huge she much have a big round ass and ever since I've been wondering what her pussy might look like what her asshole would look like since my wife has such a beautiful taste at the rear end am pretty sure she does too. Am I going on about something to crazy here? Has anyone had encounters with their mother in laws? If some what did it all go down for you?
