My name is Mark. I'm 59, in good shape, about 6' and 200 lbs, full head of blonde / grey hair. I'm married to Karen, who is 17 years younger than me. We've been married almost 12 years now, for the most part happily and with a good, mutually satisfying sex life. The only issue, the one I'm writing about, is that I have lusted after Karen's mom, Jenny, for every second of that time and more. At 62, Jenny doesn't necessarily turn heads on the street, but she is sexy. Nice eyes and smile, full breasts and just generally has aged well. From the moment I saw her when I began dating Karen, I knew she would be awesome in bed.
Over time, we've become close enough to gossip and joke together, and there have been a few moments that made me wonder if Jenny was signaling her feelings for me. At Christmas a few years ago, she gave me a "Christmas Kiss" that was a bit lingering, and during a couple of hugs, she stayed pressed against me for just a tad too long. Just recently, we were comparing our low-carb diets, and she looked directly at me while talking about eating foods not on the diet, "When I cheat, I cheat all the way. No sense in just teasing myself."
Once when using the bathroom at my in-laws, I found Jenny's panties on the floor, just outside the closet where the clothes hamper is kept. Of course, I picked them up and inhaled the scent of her sweet musky pussy while stroking my big fuck tool and thinking about bending Jenny over the bathroom counter and fucking the shit out of her. I licked the soiled spot and used the panties to wipe up the sink where I unloaded a massive amount of cum.
She also made a comment once that a woman should offer her man sex every day because that is her place in a relationship, to be available to satisfy her mate. I jacked off to that comment more than once, because I knew she was submissive and that fed my fantasies of fucking her. I was even sort of pissed that it was all wasted on her husband, Dan, who seemed to treat her like furniture.
I resolved that if I ever found myself alone with her again, which happens from time to time, I would simply make my case for how I felt about her and let the chips fall where they would. I was obsessed with feeling her pussy encasing my thick cock and hearing her cum hard on me.
Now to my story. Last week, Karen asked if I'd mind stopping by the in-law's house to drop off some items Jenny asked for. I didn't mind, their house being on my way to the hardware store I was going to, so dropping off a bag on their porch was no problem.
When I got to the house, there were no cars in the drive, so I just grabbed the bag and walked to the front door. I was surprised when Jenny opened the door just as I got to it. She looked fresh and gave me a big smile that went straight to my cock.
"Karen texted and said you'd be here about now and to let you know you left your phone at home."
Oh, shit. Can't do anything without a phone these days.
"Can you stay a minute and help me with something? I'll text Karen you're here and helping me."
"Yeah, sure, nothing pressing going on with me. What can I do for you?"
"Well, Dan is gone for the weekend helping his buddy put up a pole barn, and of course the light fixture in the kitchen has decided to go on the blink."
Fucking bingo. I immediately began to think about being alone with Jenny and gave her a good look. She had on fresh makeup, black yoga pants and a tee shirt, and I wanted to fuck the shit out of her.
