Author's note: I began 'Seducing My Mother-In-Law' while in the middle of writing a much larger story, hoping it would serve as a palate cleanser of sorts. I didn't plan to get far with it before returning to my main project, but the story quickly took on a life of its own. I finished it in record time, and now it's ready to post first even though I started it second. If you like the story, keep an eye out for my next one. Hopefully, I'll have it posted within a month or so.
Also, usual disclaimers: all characters are fictional, similarities to real-world people/events are purely coincidental, everyone involved is of legal consenting age, etc.
Attraction seems like it should be black or white. You're either attracted to someone or you're not. But I've come to realize it's not always so simple. Sometimes you're not attracted to someone at first... but then something happens and suddenly you see them in a new light. You think, huh, how did I miss this before?
Sometimes this happens in very unexpected ways. For whatever reason, there are some people that a question of attraction doesn't even enter the picture. Maybe they're related to you, maybe they're too old, maybe they're not your preferred gender, etc.
My mother-in-law was one such person for me. Martha wasn't unbecoming, but for years after we first met, I didn't see her as anything other than the mother of my girlfriend, and then wife. That's who she was and who she would always be. Whether or not she was attractive didn't even cross my mind.
Martha was in her late forties when I started dating her daughter, Christina; now she's in her early fifties. She is about 5'5", has brownish-blonde hair (likely dyed), and has a stereotypically "mom" sense of style that did not appeal to me in the slightest. Physically, she's in decent shape for her age. She does have the classic older-mom belly, but she could easily pass for a woman ten years younger otherwise.
She was funny too, although her sense of humor dated her slightly. Still, we had enough humor overlap that we'd always gotten along well. We both liked to tease people we liked, and many of our laughs came from poking fun at our spouses and each other.
Still, as I said, she was always just Christina's mom to me. Until one fateful morning.
At the time, Christina and I had just married and moved in together. Martha and my father-in-law Rick were staying over at our house, visiting for the holidays. Christina was their only child, and they were more than happy to make the eight-hour drive to see us. Having people spend several days with us always stressed me, but Martha and Rick were as good of guests as I could have hoped for. They took care of themselves well and would help around the house too. It wasn't unusual for them to do their own thing for hours at a time; they took "make yourselves at home" seriously.
Still, it caught me off-guard when I saw Martha wearing a thin nightgown for the first time. I'd never seen her wear anything that intimate, if a mom-nightgown could be called intimate, that is. It wasn't designed to be sexy, but it was a bit short, leaving about a third of her thigh exposed even while she was standing.
I was an early riser, so I was in the middle of eating breakfast when Martha joined me downstairs wearing the nightgown. Christina and Rick were still fast asleep, so it was just the two of us. I offered to make her breakfast, which she gratefully accepted. After I'd prepared it, I gave it to her and joined her at the dining table.
Martha's nightgown, short already, pulled up even further when she was seated. Her legs were crossed, so I couldn't see anything I shouldn't have, but almost the entire length of her thighs was exposed. This was the first time I noticed how smooth and athletic her legs were. I had no idea a woman in her fifties could have legs that were so attractive. That was the moment I began to see Martha not just as my wife's mom, but as a woman in her own right.
Nothing happened that day, but I would never think of Martha the same again. I admittedly began to fantasize about her, although she wasn't around enough to become a permanent fixture in my 'highlight reel'. I suspect that's how she would have stayed--just a fantasy--if it weren't for a few key factors.
The first factor was Martha's marriage to Rick. They'd been together for almost thirty years, and although they were happy together most of the time, they did have the occasional spat that left both Christina and me feeling very awkward. Christina had told me once that when she was younger, she'd overheard a conversation between them--it became apparent that her dad had cheated on her mom with a coworker. Their marriage survived the transgression, but I suspected it was a sore spot that never fully went away.
The second factor was Martha's sex life. I'm sure it's rare for a son-in-law to know about his mother-in-law's sex life, but Christina had a habit of leaving her mom's calls on speaker phone, even when I was around. This is how I overheard that Martha and Rick hadn't had sex in years and she was feeling very frustrated about it. Quite frankly, I didn't think that was an appropriate thing for Martha to share with her daughter, but that's the type of relationship they had.
The final factor was a series of coincidences that left Martha and I alone together for almost an entire day. Now that Christina and I were married, Martha and Rick had decided they wanted to move closer to us. They'd picked out a plot of land about twenty minutes away but still needed to set up with a builder in the area. They planned to spend a week with us to take care of it all, which we dutifully fit into our schedule.
Martha and Rick hoped to handle the house-business during the work week and then spend the weekend hanging out with us. And that's how it went--at first. But the plan hit a snag on Saturday. Christina's work had a call-out, and they desperately needed her to cover it. Christina apologized to her parents but said she couldn't back out. She left that morning, leaving me alone with them.
Christina's dad left soon afterwards. Rick said he needed to take care of some landscaping on their plot of land... but I suspect he just needed an excuse for some alone time. He and Martha had been bickering more than normal during the week. He said he planned to work until daylight was gone, and we should make our own plans for the day.
And that's how I found myself alone in the house with Martha.
Fantasies aside, I'd never planned on trying to seduce her. But when Christina and Rick left, the thought stuck in my mind that I had been given a golden opportunity. I might have a legitimate shot at my mother-in-law. Obviously, opportunity doesn't mean anything without desire, but I couldn't get the thought out of my head. I decided I had to try. Even if the chances of anything happening were slim, just the attempt would give me fantasy material for years to come.
Martha and I spent the morning just being lazy, drinking our coffee, talking a bit, doing some reading, etc. Martha never even bothered to change out of her nightgown, a fact I appreciated. I drank her legs in with my eyes and hoped she'd give me a chance to see more that morning, but she never did.
For lunch, we ordered pizza. Martha asked if there was anything I'd like to watch on TV while we ate, so I put on a baking show while we joined each other on the couch.
We talked and laughed together as we made our way through our food. I even tentatively flirted with her a bit, although I was careful not to say anything too forward.
After we finished eating, we cleaned up our mess before settling back down on the couch, me on the left side; her on the right.
"Well, what now?" Martha asked.
"Is there anything you want to go out and do? You're the guest, after all." I offered.
"Oh no. I'm tired and sore from all our work with the house stuff. I'm perfectly happy to just hang out here with you. Assuming you don't mind entertaining an old woman all afternoon, that is."
"You're not that old. You could easily pass for being in your thirties if you wanted. Besides, you're fun. I like hanging out with you."
"That's sweet, coming from a young man such as yourself. Women my age don't normally get that. You're what, twenty-five now?"
