My Mother-In-Law Seduced Me

Also, cheating is technically involved in the story even if it’s not the focus, so don’t read if that upsets you.

And the usual disclaimers: all characters are fictional, similarities to real-world people/events are purely coincidental, everyone involved is of legal consenting age, etc.

Hello. My name is Ryan. This is the story of how my mother-in-law and I developed a new side to our relationship.

Some background info—I’m a thirty-year-old man and have been married to my wife Susanne for about 8 years now. I’d say it was a comfortable marriage, even if we didn’t have the spark we once did. No kids yet, although we’d decided to start trying in the near future. Overall, I was happy with our life together, and aside from some innocent fantasies, I had no interest in pursuing other women.

Susanne is an only child and relatively close with her parents, Amy and Carl. Amy and Carl are in their mid-fifties, and although Carl has let himself go physically, Amy is in very good shape. I don’t know how common it is for husbands to be attracted to their mothers-in-law—although I have my suspicions—but it does make a certain kind of sense. The saying ‘like mother, like daughter’ exists for a reason.

Plus, Amy is objectively an attractive lady. She’s a bit shorter than me, with dirty blond hair, blue eyes, and amazingly smooth skin that you’d expect to see on a much younger woman. The years and motherhood had flattened Amy’s curves somewhat, but I’d later discover they were still there, even if not as firm as they’d once been.

Still, our age difference muddied the waters a bit. Even as gracefully as Amy had aged, I didn’t see her as a possible target of attraction at first. Women over forty were usually invisible to me in that sense.

But as I’ve gotten older, I’ve noticed my taste in women broadening. I still prefer women my age, but I’ve found more and more outliers the past few years. For example, I had an older coworker who I’d never paid much attention to… until I went home one day and realized that she’d been flirting with me all shift. That realization was like a wrecking ball in my brain, destroying my perception of who might be attracted to me… and vice versa. After that realization, I began to see my coworker in a new light… and I realized that despite her not fitting my usual ‘type’, she was attractive in her own way. I never initiated anything with her, but she did become a feature in my fantasy reel for a while.

My ‘aha!’ moment with my mother-in-law was even more basic. Amy and Carl visited us one fall and helped me with some yardwork. Carl gassed out quickly and headed back inside, but Amy continued to work alone with me. We were pulling weeds from our flower bed when Amy encountered a particularly troublesome plant that refused to release from the ground. I heard her struggles, so I dutifully walked over to offer my assistance, but Amy waved me off. She could be stubborn like that.

And so, she continued to tug at the equally stubborn weed, straightening her legs and using her weight against it. This left her basically bent over right in front of me, her ass hanging in the air close enough to grab. I remember thinking to myself that if Amy wasn’t my mother-in-law, I’d suspect she was giving me a show on purpose.

But then the wrecking-ball came for my brain once again. What if she was? After all, Amy wouldn’t be the first older woman who’d done some innocent flirting with me. Sure, I was her son-in-law, but maybe she wasn’t picky where she got her excitement from.

Looking back, I don’t think Amy was showing off intentionally, but the mark on me had been made. My attraction-floodgates were open.

As Amy continued to fight the weed, her body straining against it, I began to look over her body with fresh eyes. As recently as a minute ago, I’d seen her as just another older woman wearing old-fashioned clothes, but now I saw just how in-shape Amy was. I noticed her toned arms, her tight legs, her smooth skin… hell, even her ass looked good, despite her unflattering jeans. I wondered how I hadn’t appreciated her like this before.

I was still reveling in my discovery when Amy suddenly looked back at me. I knew she’d absolutely caught me checking her out, but Amy didn’t say anything other than to admit she needed help after all. Pretending like nothing was out of the ordinary, I stepped next to her and took over, my hands accidentally brushing over hers in the process. It was an innocent touch, but coming right after I’d been busted staring, I knew how it might seem to Amy.

Neither of us acknowledged it though, and I was able to finally remove the stubborn weed after a small struggle. Amy thanked me, and we moved on with our work, but the moment stuck in my mind. I began to fantasize about Amy after that, and even though it was such a small encounter, I’ll admit she became one of my favorite masturbation focuses.

For maybe a year after that, there were no major changes in our relationship, but I did begin to push our established boundaries in subtle ways. For example, whenever we hugged each other, I held her just a bit tighter and longer, enjoying the sensation of her body against mine. I began to tease her a bit more too—not flirting exactly, but definitely flirting-adjacent.

Maybe most boldly, I found ways to touch her more often. Nothing inappropriate, but little touches like a pat on the back, a grasping of her arm, or a quick run of my fingertips along the base of her neck. I sprinkled these throughout our normal interactions, hoping that by keeping it casual, my true intentions wouldn’t be given away.

Normally I wouldn’t have pushed these boundaries with one of my fantasy-women, because I knew that even small acts could be a slippery slope into something more. But I figured I’d be okay with Amy. After all, she was my mother-in-law. People slide into affairs with coworkers all the time; nobody ever actually sleeps with their wife’s mom. Because I knew it would never go further, I figured what harm could there be in some innocent fun?

And at first, that’s all it was. Even better, our relationship improved significantly during this time. Amy wasn’t a bad mother-in-law by any means, but we’d never really clicked before. Part of it was probably our generational difference, but I suspected the bigger reason was her job. Amy was a risk manager nurse for a regional hospital group, and her job often entailed being the bad guy, whether to out-of-line hospital employees or overly litigious patients. Overall, Amy was a nice person… but she never fully shook her ‘you-don’t-mess-with-me’ attitude even when she wasn’t at work.

But once my perspective of her changed, we did become more comfortable around each other. We laughed at each other in new ways, talked with each other more frequently, and exchanged friendly ‘love-yous’ all the time. Even Susanne noticed the shift in our dynamic, complimenting me with how impressed she was that I was getting along so well with her mom. Turns out it’s easier to connect with someone if you’re beating off to them semi-regularly.

I don’t know if what happened next was inevitable, or if it was a random twist of fate. In the end, the result is the same—it happened.

Susanne and I were visiting her parents for Father’s Day weekend. Susanne had planned a father-daughter date to surprise Carl with, and she’d brought me along to keep her mom from getting too lonely in the meantime. It was a sweet gesture—a dinner and a movie—and I knew her dad would love it. I wasn’t necessarily thrilled to spend an evening alone with Amy, even with our new dynamic, but I knew it was the husbandly thing to do.

The weekend did get off to a bit of a rocky start. Carl had just been diagnosed with another small skin cancer, and Amy harassed him for not listening to her and being more careful in the sunlight. Eventually Susanne intervened and told her to drop it, but it set an awkward tone. Amy gave me a parting shot too, saying that she hoped I’d take better care of myself than Carl did, especially since as a pale redhead, I was very high risk myself. I’d just nodded obediently and changed the subject.

Fortunately, the weekend did improve. We had a nice at-home dinner that Friday night, watched some TV, and went our separate ways to bed—me being sure to give Amy another long hug goodnight, of course.

Saturday is when everything changed. My first foretaste happened that morning while Amy prepped to hem my pants. I’d bought some dress pants from a men’s clothing store but forgotten to have them pre-hemmed. For now, they were essentially unwearable with the legs extra-long and the fabric hanging loose. Neither Susanne nor I had experience hemming clothes, so I took them back to the store just to be told that because the pants had been outside of their protective packaging, I’d need them dry-cleaned before they could be worked on. I was very frustrated and refused to give them any more business. Instead, I’d asked Amy if she’d mind handling it for me with her sewing machine.

And so, I found myself standing on an ottoman in Amy and Carl’s living room, dress pants on as Amy fitted them around me. Susanne was there too, so it was far from a private experience. Yet as Amy ran her hands along my feet and calves, finding the right places to pin the fabric, I found myself enjoying her touch more than I should. Occasionally Amy would look up at me and ask me how I liked the length, and I couldn’t help but appreciate how she looked on her knees in front of me. The inherent submissiveness in her position is not something I ever expected to see from someone as strong-willed as Amy.
