Author's note: Like most of my stories, this one doesn't immediately dive into action. It builds the scene and characters first, with a heavy focus on the seduction process itself. The main character, Ryan, may be frustrating to some with his initial passivity and uncertainty, but that was a deliberate choice. I wanted to explore a story where the mother-in-law is the initiator, and the son-in-law is the willing but reluctant target.

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.

Soon enough though, Amy had the pants fully pinned and the moment passed. I changed back into my jeans and gave her the prepped pants to finish later.

This was such an insignificant moment that I wouldn't have given it a second thought, except I was already primed to appreciate all interactions with Amy. And so this encounter only heightened my focus further. I had the bold thought that if I did some real flirting with Amy in my current state, I could get enough fantasy-material to last me for months. Besides, what was the harm? Husbands compliment their mothers-in-law all the time. I didn't think Amy would give it a second thought.

The rest of the morning and afternoon went by quickly. True to my plan, I did flirt with Amy in small ways, telling her I thought her jeans looked good on her, saying that I hoped Susanne aged as well as she had, and—my personal favorite—giving her a quick neck massage after I helped her clean up lunch. Amy was a good sport about all of this, even flirting a little back, saying that she could tell I'd been working out and Susanne was lucky to have a guy like me.

Amy had never been so openly nice to me before. I should have started this years ago, I thought. Who knew some light flirting was the missing piece to getting along?

Eventually, though, it was time for Susanne and Carl to leave for their father-daughter date. They hugged Amy and me goodbye, Susanne reminding me that I had a job to do keeping her mom entertained in the meantime. I assured her I would, and then they were gone.

Amy and I were now alone.

"Whelp, time for us to figure out dinner for ourselves. You mind frozen pizza?" Amy asked.

I shook my head, so Amy went to start the oven. I followed her into the kitchen as she prepped the pizza, casually observing her movements. She was very mobile for her age, and I enjoyed watching her bustle around. Once she had the pizza cooking, she turned to me.

"You want a beer or something? I'm about to pour myself some wine, if you'd prefer that."

"A beer's fine," I said, as Amy pulled one from the fridge and tossed it to me. I cracked it open and sipped the foam that released.

We began to make small talk as Amy poured herself a rather large glass of Cabernet and began sipping from it. We stayed in the kitchen as the pizza cooked, chatting about our lives, our work, our friends, and so on. I don't know if it was my own perception of Amy that had changed or if she'd warmed to me a bit more, but I was really enjoying myself. I'd never seen Amy so engaging. In fact, she reminded me a lot of Susanne back when we'd first started dating.

The pizza was done a short time later, but we didn't even leave the kitchen to eat it, as we were still engrossed in our conversation. Only once we'd finished our alcohol and food did we finally break our connection to clean up.

"Well, we still probably have another few hours to kill. I'm gonna grab some more wine, and then maybe we can watch some TV?" Amy suggested.

"Sounds good to me. I'll take another beer too, if you don't mind."

"Not at all. I'll grab it for you and meet you on the couch." Amy smiled.

I retreated to the living room and plopped onto the large couch in front of the TV. Amy joined me a minute later, wine in one hand, beer in the other. I took the beer.

"Anything you want to watch?" Amy asked me, offering me the remote.

"You pick. I'm the one who's supposed to entertain you," I pointed out.

Amy put on a comedy show, which we watched silently for ten minutes or so, sipping on our alcohol. About this time, Amy's dog, Bella, made her way up to the couch and jumped into the open spot between us. I began to pet Bella absentmindedly, but then she rolled to her side, inviting me to pet her belly. A sucker for dogs, I turned my full attention to Bella and gave her the belly rub she was waiting for.

Amy noticed my distraction. "Bella's got you wrapped around her paw, I see."

"I couldn't say no to this," I looked at Amy and gestured at Bella flipped next to me. "She asked me so nicely."

"Well, she's definitely enjoying it," Amy said, while giving me an appraising look. "You're good with your hands."

"I just let them go where they feel like they're needed," I shrugged.

"Well, my neck muscles can vouch for your instincts. Even in that short time you worked on me, I feel a lot less tension."

"Happy to help," I said, smiling as I continued to pet Bella.

Amy watched me for a few seconds before smiling back. "Bella says 'thanks, Ryan! I don't get as much attention as I used to! Your hands feel great!'"

I played along. "Oh, you're welcome, Bella! I'm happy to give you all the attention you need!" I switched my gentler belly rubs to more vigorous pats.

Amy continued miming for Bella. "Ohh, that's the spot, Ryan. I like it a bit rough like that."

Amy spoke so casually that I almost didn't notice the potential double meaning behind her words. If it had come from any other woman, I would have thought she was coming on to me. But this was Amy—my mother-in-law that I'd known for years. Surely, it was a coincidence, right?

"Oh yeah, you like it a bit rough, Bella?" I tested, continuing my pats along her belly.

"I do," Amy said in her Bella-voice. "Not too rough, though. Just enough to remind me there's a man in the house who can take care of me."

Holy shit! Could Amy really be doing this? I tested further. "Aw, poor Bella. Does Carl not give you enough attention?"

Amy fake-pouted. "No, he doesn't. I've been so lonely, just waiting for a man to love me again."

My mind was reeling by this point, but I didn't get the chance to test more. Bella, apparently tired of my pats, slid off the couch and walked away, back to her crate in the storage room.

I laughed and directed myself back at Amy. "I guess she decided she had enough attention after all."

Amy shrugged, the game over. "Who knows with Bella. Maybe she just got sleepy again."

Silence hung in the air for a moment, and so we looked back to the TV. But I was no longer paying attention to it, my brain replaying the last few minutes. Flirting was one thing, but Amy was doing more than some innocent flirting. Assuming she'd been doing it on purpose, of course. But the fact was I couldn't tell. I didn't know if she'd been coming on to me or if she thought it was just more innocent flirting or if it was all a coincidence and Amy really had just been acting as Bella. I just didn't know.

It didn't really matter, because it's not like I was going to try anything, but the uncertainty still tugged at me.

"Thanks for agreeing to keep me company tonight," Amy said, turning her attention away from the TV. "I know you have other things you'd rather be doing than hanging out with your old mother-in-law."

"It's no trouble at all! You're far from old, and besides, I'm having fun," I replied, and I meant it.

"That's sweet, Ryan. And I'm having fun too." Amy smiled. "So, since it's just the two of us, I've got a question I'd like to ask."

My heart picked up its pace. Surely not, I thought, but I just nodded for her to continue.

"You and Susanne have been together for a while now. Should I be expecting grandkids at some point?"

I couldn't help but laugh. Not the question I'd been expecting. Amy misinterpreted my laughter, because she quickly followed with, "I understand if it's none of my business. I just couldn't resist asking. Blame the wine."

"No, no, it's fine," I reassured her. "You just caught me off-guard. But yes, you can expect grandkids. Susanne and I have been talking about trying soon, in fact."

Amy's face lit up, like I'd let her in on a big secret. "Ryan! That's so exciting! I'll admit I was a little worried that you guys might not want kids. Or at least not Susanne—I know she's told me in the past that she's not always been thrilled about the sex part of making babies."

I blushed at that. I didn't realize Susanne talked about her sex life with her mom.

"I mean, I think we're both on board with the idea of kids. I can't speak to the rest though," I replied awkwardly.

"Don't be embarrassed, Ryan. You know Susanne and I have always been close," Amy said, brushing off my discomfort. "Are you guys doing okay though? Sex is a healthy part of marriage. When libidos are mismatched, that can cause all sorts of other problems in the relationship. I just want to make sure my daughter isn't causing needless frustration. I want the best for both of you."

Even as much as I'd been connecting with Amy this evening, I wasn't ready for this conversation. Sure, maybe Susanne wasn't as into sex as she'd once been, but I didn't think that was any of Amy's business. "Susanne and I are doing great. I appreciate the concern though," I responded dismissively.

Amy looked at me pointedly. "We don't have to talk about it, but I do want you to understand that if either of you are frustrated, ignoring it won't help anyone. I apologize if this is too personal, but Carl and I went through something similar, except I was the one with the higher drive. Carl just thought I cared more for physical intimacy than emotional intimacy, but he didn't realize that for me physical intimacy IS emotional intimacy. Still, I let it go, and there's been a distance between us ever since. I wish I'd addressed this decades ago, but now it feels too late."

I was becoming more uncomfortable now. If this had been one of my fantasies, I would have said something about how maybe I could help us both out. But this wasn't a fantasy. Here in the real world, I thought there's no way such a clumsy come-on would lead to anything but regret and shame. And besides, fantasizing about Amy was one thing. Acting it out was another step entirely, and one that I wasn't sure I'd want to take—if I even could.
