Introduction:

We met Sean and Betty at dinner the first night on a cruise ship. It turned out they only live fifty miles from us. We said we'd try to get together sometime after the cruise, but that never happened, well, except for Sean and me.

The next morning, Arthur and I went hiking in St. Maarten, while Betty and Sean went horseback riding. We enjoyed their company at dinner again. Even though his wife was, so far, ever present, I had to admit to myself that Sean was interesting, to say the least.

The next time I met, Sean was in the gym on an upper deck of the ship - a day at sea. Hubby Arthur was running outside on the very top deck - not a gym person - and Betty managed to stay shapely without exercising at all. Although we'd all managed to tell our life stories, minus many secrets, at the dinner table, Sean and I managed to strike up a conversation while we used the two treadmills and, later, the stationary bikes. My gym clothes do show off my figure. And Sean is no slouch either - not a muscle man, just obviously fit with a powerful body revealed in his tank top.

Sean suggested we go for coffee, and we got in touch with the other two by cell phone. Betty came up from their cabin in a colorful shift, her bikini underneath. Arthur took a shower before he joined us. After a nice chat, we all went on about our business, though we sat for drinks with them poolside and saw them again at the dinner table. Of course, Arthur and I were having sex morning, noon, and night whenever we were in the cabin.

On the third day, Curacao, Arthur took an excursion to see a cave, but we'd been to that island before, and I wasn't that interested in seeing the famous cave again. I said I'd go shopping after the gym and kissed Arthur adieu. Betty went to a rain forest which held no interest for Sean. Once again, the morning started out in the gym. Just after I started my workout, Sean arrived in his shorts and tank top. We worked out together, and it almost became a challenge session. “I could beat you, but I wouldn’t want to embarrass you,” I claimed as I ran out of steam.

Then coffee - Irish coffee - and another. And a long chat. Where'd you go to school? What did you study? Sports? Yeah. The conversation got more personal. Boys must have chased you everywhere. Ladies' man, huh? It was clear there were sparks. And opportunity.

"You really are a beautiful woman, Margo."

"Why thank you." Long silence. Staring at each other, not sure what to say.

"Are you thinking what I'm thinking?" Sean offered.

"Are you thinking what I'm thinking?" I replied.

"I'll be in cabin 1436."

"I need a shower."

"I do, too. Use ours."

Sean headed aft, and I discreetly departed forward. A few minutes later, I pressed the buzzer at his cabin door. He had already slipped the "DO NOT DISTURB" card into the little slot.

As soon as the door closed, we started ripping each other's clothes off, what few we were wearing. Deep kissing ensued, with Sean's hands pushing my breasts up and mine holding his fully erect cock. I was impressed that had come up even before I arrived.

"Shower first," I insisted. I wasn't about to get in bed with a new man smelling the way I did, especially since there may have been evidence of Arthur's presence in certain places.

We squeezed into the little shower stall and started to lather each other up. It felt so nice, his hands gliding smoothly over every part of my body. I loved it when he softly washed my boobs and thoroughly cleaned my pussy. I turned him to do his back and washed his cock while reaching around. Then I turned him again to do his chest. Then I got down on my knees to wash his feet and legs. His beautiful cock was in my face in the narrow shower. I caressed his balls and smoothly stroked his soapy shaft once again. And when I was sure the spray had rinsed that off, I took it in my mouth and listened to his moans as I slurped it in and out.

Sean stood me upright before he would have cum and squeezed us tightly together. He used his cock to stroke front to back between my legs, giving us both a nice feeling. Eventually, I leaned back against the shower wall and guided him inside me. We fucked like that for a few minutes, 'til it got uncomfortable. I turned and guided him back into me from behind. His thrusts became more urgent, and then I felt his eruptions from each stroke deep inside me. We separated, and I turned to hug and kiss him with his limp organ pressed against my belly.

"That was wonderful."

"Oh yes it surely was."

We shared the same towel so as not to arouse suspicion with Betty. I used a wet washcloth between my legs first so there was no evidence on the towel.

There was a stiff spot on the sheets when we got in bed. Betty and he also had obviously been enjoying themselves.

"Sorry about that," he said. I just giggled and pushed him back onto the bed.

I knelt next to his supine body and took his organ in my hand. It was already filling out again, and I couldn't resist licking it all over and taking his balls one by one in my mouth. Before long, he nudged me down and we lay facing each other’s sex. I lifted one leg up so his head could go between my legs and took his shaft in my mouth.

I hadn't had much of an orgasm in the shower, but his ministrations with his tongue sent me over the top. Just as that was subsiding, he pushed two fingers deep into my vagina. I came again even stronger.

I had backed off a bit on his cock and only had the tip in my lips. Suddenly, he shoved it deeper into my mouth; he could hold off no longer. I have enjoyed the taste of a man's juices ever since that first time in high school - well another boy was fucking me at the same time, so my pleasure index was pretty high. Shot after shot blew into my mouth, and I savored every drop of Sean's semen.

We were fairly well spent after that, so we just went over to their balcony and leaned against the railing. It was on the water side, but still I wondered if someone across the harbor would notice two naked adulterers there in a pair of binoculars.

After a few quiet moments, Sean asked, "It's not your first time, is it? Cheating I mean."

"No," I sighed.

"Me neither."

We stayed there quietly for several more minutes, just enjoying the salt breeze against our bodies.

At some point, Sean found his way around behind me, took my boobs in his hands from behind, and played with my nipples. I could feel him getting harder against my back. After a while, I pushed my rear out and let him enter me again. The distant motion of crafts in the harbor seemed to match his slow and deep strokes that were so satisfying.

Eventually, we meandered back to bed. I lay on my back and Sean climbed over me, smothering me with kisses that eventually moved all over my body - feet, legs, boobs, tummy and pussy - before I begged him to fuck me again. I'd had a couple more orgasms with his foreplay. One more came as his climax neared. Finally, with a deep moan, he let go. God, I was enjoying this man!

Sean watched me clean up again with the same washcloth and put my clothes back on. We hugged and kissed again - he was still naked, and I was about to slip out the door. But even though I had to go shopping to confirm my cover story, I couldn't resist taking his cock, covered with both our juices in my mouth one more time. He let me suck on him 'til another hot load of his cum pulsed into my throat.

It was awkward trying to meet again on the ship, and it didn't happen other than a couple of deep kisses when nobody else was in the gym. We exchanged secret email addresses on the last morning.

A few days later, we started to write back and forth, telling each other how wonderful that day had been and how nice our kisses were and how nice it would be if we could somehow get together again.

We engaged in fantasy emails about what we would do if we hiked off into the woods somewhere together or took a canoe on a hidden lake or crawled into a secret cave. We advanced to phone sex when we both had some privacy. That was a new delight for me.

I had heard about a video phone chat service for lovers - this was before the explosion of video conferencing that we've all learned to hate - and suggested we try it. Let me just say it was incredibly exciting to watch each other masturbate on the computer screen. Sean loved it when I fucked myself with a dildo during the show. I loved watching his juices shoot out when he came.

But after each episode, I would say, "I wish that cock was inside me for real."

And Sean would say, "I wish it was fucking your hot wet cunt til I couldn't hold off filling you with my cum."

Finally, we couldn't resist and started working on a plan. I told him about the hiking trail midway between our homes, the one where I had run into George, and our plan centered around that. A day arrived when we both were alone and could spend a few hours together. We both drove to a trailhead and parked our cars.

I got into the front seat of Sean's car and we immediately started making out. Soon I had his cock in my hand and his hand wandered under my tee shirt before he opened my shorts and slipped it into my panties. It was getting hot and I'm sure we would have both cum had another car not turned into the trail head lot. We quickly put ourselves back together.

Like married hikers, we got out of the car, clipped our water bottles to our shorts, sprayed each other with bug spray and headed down the trail. I showed him the spot where George had fucked me. "This is where I started cheating," I told him. "His name is George."

I felt like it would be awkward to take Sean at the same spot. So we continued past there to a gurgling brook, still completely out of sight of the trail.

We sat on a large rock and resumed our play that had been interrupted in the car. We took time exposing ourselves at first, but the passion soon overcame us and my shorts and panties ended up on the forest floor. Sean pushed my tee shirt up and undid my bra. He knelt in the leaves and sucked and licked my nipples. Then his face was between my legs and my orgasm started to build.

"Oh Sean, fuck me, fuck me now," I begged.

But the rock didn't work too well as a chair or the edge of a bed. When I leaned back, there was no place for my elbows. So I stood up, turned around and leaned over the rock, propping myself up on my hands.

Sean really loved that view and spent a few more minutes licking and fingering my pussy. Oh my god, I wanted his cock.

"Please, please, fuck me. Fuck me now!!"

He stood and grabbed my tits from behind and played there for a bit. Then he finger-fucked me one more time before I felt his wonderful shaft push all the way in. "Oh god, Oh god." Not only that, but his still wet fingers moved to be rimming my asshole. As he shoved in again and again, I felt spit land on my asshole and soon there was a finger in there, too. "Ohhhhhhh. Ohhhhhhhh." I was sure my moans carried all the way back to the trail. "Oh Sean, Sean."

"You can fuck me where your finger is if you want," I managed to mutter. More spit on my butt hole and his slimy shaft pushed into my ass. I managed to hold myself up on one elbow and pleasure my clit with the other hand as his strokes intensified in my rear.

When he was about to cum, he pulled out and entered my vagina again. A few strokes and his hot juices started to fill me. I could feel them leaking out as stroke after stroke pumped more into me. "So good. So good," I moaned 'til I came myself.

I stood and a blob of everything ran down my leg. The only thing I had to wipe myself off was my panties. Sean let me use his tee shirt and then rinsed it off in the brook. We climbed back over the ridge. When we were sure nobody would see us coming out of the woods, we got back on the trail. I'm sure that people who passed us wondered how that shirt got so wet.

Further on, behold, the trail passed behind a small motel I'd heard was a perfect no-tell venue. We looked each other in the eyes.

"Are you thinking what I'm thinking?"

"Are you thinking what I'm thinking?"

We checked into what would become our home away from home, so to speak, for the next few months. As we undressed and lay down in the bed that same day, he asked me, "Tell me about George."

While his hand played with my pussy, I told him about the first time in high school that I had been with George and didn't have to exaggerate George's skill. As Sean sucked on my nipples - "Keep telling me," he begged. I told him several more George episodes, including a couple of orgies.

When I said, "Then George's family moved away," Sean's face was pressed into my cunt and his tongue was making it hard for me to talk. I pushed him away and got him to lie on his back on the sheet. I climbed over him and mounted his very hard pole.

As I rode him, he didn't give up on his inquest. "But you haven't said how the time in the woods happened." And, between moans and exploding breaths, I described how we ran into each other and all the physical details of the occasion.

I got him to tell me about how he started. It was a girl he’d had a crush on in high school, but never got around to dating. They ran into each other at a party. She’d had a crush on him, too. One thing led to another, and they both ended up committing adultery. I imagined the two of them as his cock slid in and out of me.

Finally, he asked, "So was that the last time?"

As I bounced up and down on him, I had to tell him about Melanie. Sean could hold off his ejaculation no longer when I told him Melanie had watched George fuck me.

"Did you go back?"

"Yes, but they bring other guys to make foursomes when I visit," I finally told Sean.

It began to dawn on me where this was headed. And it won't surprise you that a month later there was a new foursome. I got to watch Sean fuck Melanie, and he watched George deposit his load in me. I seemed amazed when we two girls put on a show for the boys. FF 69 made plenty of opportunity for the two boys to take over after our first orgasms.
