Desc: Erotica Sex Story: At a little more than half-way through my forties, I've become insatiable for sex, right at a time when my husband seemed little interested. Then I found out just how interested my son-in-law, Adam, was in his wife's mother.

Chapter 1

Martin and I have been married for twenty-five years now and we've been about as happy as you would expect. Like many couples, we've had our ups and downs, none really too serious and we've raised our daughter, Pamela, who, today, is a wonderful woman, married to Adam, our son-in-law, for five years now.

Pam is a middle-school science teacher and Adam has his own computer consultancy business which he, luckily in our view, can operate from their home.

My husband, Martin, has had several businesses during our marriage, mostly rather successful, we've done better than most in our years together and Martin is in the throes of developing a new business after selling the former one earlier in the year. He's one of those who may never really retire.

So, we decided that before he became super-busy with the new business, we would drive our camper van down to visit Pam and Adam for a week, then head back up so Martin could get to work setting things up. He is an excellent entrepreneur in most ways but when it comes to computers and setting up a network, he knows his limitations. So, he had hired Adam to come back with us to Madison to spend a week or so helping Martin get the computer systems up and running.

We had a fun time even though I knew Martin was eager to get back and begin the new venture, so after a splendid week in South Florida enjoying the sun and ocean, we got in our van and headed back, Martin, myself and Adam.

Now, I know you're reading this because the story is about sex, well, it is so let me tell you about one change in our relationship over the last few years.

I just turned forty-seven, Martin is fifty-four. His libido has taken a downward turn while mine has skyrocketed. I'm honestly the horniest I've ever been, even more than when I was thirteen and masturbated several times a day. And, yes, I'm now masturbating several times a day. I even ordered some toys for the first time in my life and quickly get them out as soon as Martin leaves the house for whatever reason or other.

I know I'm attractive enough to attract men and, yes, I do get hit on at times, sometimes subtly, sometimes rather direct. I had a young man in the grocery store parking lot recently ask me if I'd follow him back to his apartment as he was getting into his BMW. I almost did. I went home and masturbated through two orgasms instead. I've kind of wondered since why I didn't visit his apartment.

My specs are five-five, one-eighteen pounds, 34, 24, 36, B-cup and they look good. Not quite like when I was sixteen but almost. I wear a bikini that gets lots of looks when we're at the club pool or the beach in Florida at Pam and Adam's place. I think if I'd been C- or D-cup all these years, they might not now look so good so I'm happy.

We loaded back up at the end of our stay, except this time, we had Adam with us along with his things to get by for a week with us. Our van can sleep three but only when we're parked; there's a small one-person bed up above the driver's compartment and at night, the driver area and part of the back converts into a double bed. A small kitchen area and bathroom complete the rear of the van. Cozy is a nice way to put it.

I'm sure you've thought ahead about what might happen in a story like this on this kind of website and, well, you wouldn't be far off.

I had always admired my son-in-law, he's handsome and intelligent, just an all-around nice guy. We never really flirted like I know happens. In fact, I have a friend who tries to let her son-in-law see her naked as often as she can. No, so far we've kept our hands off each other and our clothes on.

We drove about eight hours the first day, stopping in a small town where we had supper then found a campground and set up for the night. Now, sleeping is never very restful in one of these campers so we all got some sleep but not quite enough.

The next day, Martin started out driving, went about four hours, then went back to nap in the single bed while Adam drove and I sat with him. As I've said, I was horny and aroused all the time and this was no different. As we talked about this and that as he drove, I began to fancy what my daughter's husband might be like in bed.

The more I thought, the hornier I got, of course, and I was soon trying to rub myself without him being any the wiser; we women are better at that than most men are, thank goodness, and the miles went by as the time went on.

About two-fifteen, we pulled over and Martin came forward to drive again as Adam got back up in the bunk to nap. We drove along for a while, me sitting there, lost in lascivious thoughts of my son-in-law just a few feet away, drowsing away, and just made the decision to go back and get in the bunk with him. I made sure to yawn several times, then told Martin that I was going back for a nap as well.

I went back and leaned up, Adam was awake and I asked him if there was room for me to kip out next to him. He said it would be easier for me if I was up next to the front bulkhead so I climbed over him and was soon wedged between the wall and Adam. I had noticed, of course, that all he had on were boxers which did little to cool my ardor.

It was cozy as we rocked along and I was soon asleep, then, after a half-hour or so, we hit a large bump or pothole which threw us some and I woke up. I woke up to a rather stiff object pressing in between my butt cheeks, an unmistakeable stiff object.

We rocked along a little longer and I began to move against the pressing as the miles went on. The pressing from Adam's end seemed also to be deliberate but I couldn't be sure.

A few more miles went by and I slowly reached my hand back and, there it was, outside of his boxers. I quickly pulled my hand back, then, several minutes later, just let my hand return to hold his cock. I was breathing heavily, of course, by then and my heart was racing.

Even though Adam had left my hand gripping him, I couldn't be sure that this was what he wanted though I knew it was certainly what I wanted. I ran my fingers along the entire length and my heart raced even faster. Oh, I wanted what I was touching, I wanted it so badly. He still let me hold him, he was still going along.

Then, the pressure against me was stronger and I decided to pull my shorts down and work one leg out of them which took some contorting to pull off. I reached back and, yes, there it was, long, thick, hard, as I eased my panties aside and pushed back as I held him.

Adam slowly pressed forward as I felt his cock tip slide under my panties and past my labia. I could have almost cummed right then it was so erotic. Just below us, Martin was driving along as I was above, over his head, accepting my son-in-law's penis sliding along the outer lips of my pussy.

He began moving back and forth sliding his cock along my wet and engorged pussy lips going slowly back and forth. My panties were holding the upper surface of his cock tight against my lips as he slid back and forth; the feeling was wonderful.

Adam's hands moved around me and under my blouse as he pulled his cock back and repositioned it, then pressed it up into me. He was fucking me. Then he pushed further inside and began taking short strokes in and out of me. I pulled my bra up as his hands cupped each breast and squeezed gently as the miles rolled by.

His cock was so hard, not at all like Martin's on the rare occasion when he wanted sex with me, Adam was hard and swollen and throbbing inside me. I moved as much as I could in the tight space we had but most of the fucking was up to Adam and he was doing me the best I'd had in years.

"Oh, Louise, god, I've wanted this ever since I first met you. You feel so good, oh, I can't believe we're doing this."

I turned my head and whispered back, "Well, we can't get too noisy can we? But we can enjoy being together right now. You really feel wonderful."

"Mmm, you feel wonderful, too, so tight, I'm not going to last long doing this, Louise, I hope we can do this more than just this once."

"Yes, I do too, of course, we have to be careful, but this is just so wonderful. You're making me very happy, Adam."

He just kept going really slowly but it added to the erotic feeling of our elicit coupling just inches away from my husband. Then, my heart started feeling like it was skipping a beat and I could feel perspiration along my brow as I welt warm all over. Little shudders and trembles ran through me as his cock slowly went back and forth. He was pulling back each time so far that he came out of my body. So, each stroke back inside me parted my labia as his shaft went deep.

"Oh, it feels incredible, Adam, oh, fuck me just like that, it's so good," I whispered.

We had gone so slowly that it took quite a while to come up to an orgasm but, oh, my, when it happened, it released inside me like a bomb. I shook and shuddered as wave after wave of ecstasy broke over me. It was the most magnificent orgasm of my life, no doubt because of the slowness of our union and the taboo spiciness that it added with him being my daughter's husband and us doing it right above my husband's head.

Then, Adam pushed hard into me as I tried to move my hips around and I was concentrating on using my pelvic muscles in such a cramped space; I just squeezed and squeezed until I heard him moan and the warm throbs of his semen hitting deeply inside for the first time but I hoped not for the last.

"Oh, Louise, that was incredible. You are so good, even better than I'd imagined," he said as he kissed the back of my neck. He kept moving inside me, I just never wanted it to end. We slowly fucked for over an hour more.
