One evening while my Ex- Wife was making dinner, she said that she had made enough for us and some extra portion for her mother who lived a few miles away. Her mother was a widow who lived alone and didn't cook all the time for herself, so every once in a while my Ex would send food over to her.
After we ate dinner, my Ex called her mom but she didn't answer and left a message about her dinner. My Ex told me, "Go ahead and take the food over to mom." She gave me the keys to her mom's house just in case she wasn't home.
So I drove to over to my MIL's house and saw my MIL's car in the driveway. I walked up to the front door and rang the door bell, waited a little bit with no answer. Rang it again with nothing happening again. So I used the key, opened the door and announced myself. I didn't get any response again. The house was quiet as I walked into the kitchen and put the food in her fridge. It now concerned me that my MIL, Katherine was not responding. I walked down the hall to the back of the house to see if she was there and okay. I didn't find her so I got a little panicked.
Then, I peeked into the backyard to see if she was out there and I saw a light on in the little building that used to John's (FIL) "man cave". It was his private space for the all the hobbies he had.
I walked out there and looked into one of the windows to see if Katherine was out there. And to my surprise she was there with another woman. I didn't know what they were up to, but Katherine had redecorated the room with her things and had taken all of John's things out of there. There was a bed in the middle of the room that had some mechanical attachments connected to it, and there were other chairs and devices pushed up against the walls.
I was intrigued with the decor and wondered what was going to happen in there between the two women. A brief description of Katherine and her "friend". Katherine was of German descent, 60 y.o.,5'9", 150#, 36DD-30-38, blonde hair, blue eyes. Her friend had long reddish brown hair, blue eyes, 5'6" 130#, 34C-26-36, maybe in her late 20's?
They were standing next to the bed, facing each other, talking, then they came together and started kissing, passionately. They traded tongues and spit for a few minutes then started undressing each other. The clothes came flying off the both of them so quickly, it looked like a tornado. My jaw hit the ground as I got a front row view of my MIL and her friend completely naked in a matter of seconds. In those few same seconds, my cock sprang to life too, as I had a raging hard-on that almost hurt.
They continued to kiss and grope each other as they worked their way over to the bed. When they bumped up to the bed, Katherine pushed her friend down onto the bed and commanded her to lay on her back and to hang her head over the edge of the bed. When her friend got in position, Katherine planted her crotch right onto her friend's mouth and Katherine yelled out, "Eat my pussy, bitch!"
Her friend started licking and lapping Katherine's hot pussy as Katherine grabbed her friend's tits and squeezed them and slapped them. Katherine started rocking forwards and backwards rubbing her crotch across her friend's face as her friend reached around and grabbed Katherine's nice big ass cheeks.
This went for a few minutes, then Katherine lifted herself off of her friend's face and again commanded her to get up on her elbows and knees and point her ass off the edge of the bed. Her friend took position and Katherine got behind her and planted her face right in her ass cheeks. She started licking her ass crack from the very top all the way down passing her butt hole, continuing to her perineum, then to her dripping wet pussy. She kept taking these long passes over her ass for several minutes, driving her friend into ecstasy. Her friend was moaning and sighing with pleasure as she was getting close to cumming. Katherine then said, "You're not cumming, are you?" Then, Katherine swatted her ass.
