My Mother In Laws

So my mother in law came to visit, when she's visits she ends up sleeping in the kids room, after her last stay and after she left, I was in the kids room and found a pair of her panties in the kids room, without thinking too much I ran to my wife lmao to say your big ass mother left her panties she had against her pussy that pushed you out on that pair of panties and now it's in my kid's room she laughed and so did I, now my wife and her mum has huge asses fuck and am a huge fan of big round clean ass yummy yummy.

I went to a meeting when I got back home, I get sexual with my wife but she really stocked me and surprised me of after me peeling down her pants I see the biggest panties ever worn on my wife's body, and these panties she has on isn't hers but her thick big ass mother, I don't know about other men here but I grabbed the opportunity and put my head in between her thick milky legs and brought my face right to the pussy area and I inhaled the long breath I'd ever taken in hoping from the heat of my wife's pussy my mother in laws panties would start to give off her pure perfume and I did the most weirdest thing I start to suck on those panties to try and access my wife's pussy and I kinda liked it.

What does this mean what is going on with me is this normal fuck was it an embarrassing thing for me to have done?
