So I’ve been getting closer and more touchy with my MIL in recent months. Hugging her tight and her reciprocating and squeezing me into her chest. A little flirt here and there. Wife and I visit my in-laws for brunch on Sundays usually. They only have one bathroom and a closet with their hamper so I take advantage every visit to snoop. Recently my MIL started wearing thongs! She’s also started dressing sexier but I took it as part of her new job as a hair stylist.

Anyway, my wife has told me that her parents haven’t had sex in years. My FIL has also confessed the same while drinking a few times. Weird thing is my MIL has been working late on Saturdays lately. She always talks on the phone with my wife on her way home and the call always ends with my MIL saying “Ok I’m home. Gonna shower and go to bed.” That got me thinking so I decided to go over last Saturday and have a few beers with my FIL. Indeed my MIL came home 3 hours after her shift was supposed to end! She rushed into the house and went straight to the bathroom to shower.

I waited for her to come out and when she did I rushed to the bathroom and met her by the door in her bathrobe. I told her she didn’t even greet me properly when she got home so she smiled and extended her arms and brought me into her chest “Sorry come here! I just needed a shower I’m so tired from work.” I hugged her back and could feel her bare breasts under her robe. I hope she felt the raging boner I got immediately from that hug. Then I went into the bathroom.

Her used clothes were at the top the hamper and I immediately spotted a pair of black lace cheeky panties. Another new pair I hadn’t seen before so I was excited to give it a good sniff. They were super wet and oh boy was I surprised when I put them up to my nose! It had the unmistakable scent of cum and they were still warm and gooey. I thought my dick was going to explode I’ve never been so hard before! Took me less than a minute to bust my load and add it to the panties!

So now I know my MIL is cheating. Should I try to find out with who?? Should I use this in my favor?? It turns me on so much to think it’s a customer from work getting a “special after hours service” what if it’s more than one customer and she’s turning into a cock slut for any man that needs to be “serviced”??
