It was dark outside and, given the clock time, I guessed we were in North Dakota. Annie was asleep on her side against me, an arm and a leg laying across me. There were no features to see in the darkness that would give a hint to where we were. The train schedule suggested that we might have passed Williston, North Dakota. But I didn't know whether we had passed that stop.

My watch (converting to Central time) told me that we had 45 minutes until our dinner reservation. I gave Annie a kiss and quietly called her name. She stirred and her eyes opened.

"Hi there. We must have worn ourselves out. We all fell asleep."

"Where are we?"

"I don't know. But we've got dinner reservations in 45 minutes."

"Hey guys," I called out to Catie and Ted. That stirred them from their sleep.

"Dinner in 45 minutes!"

There were grunts and groans as we all got up from our comfortable positions in the two beds. Catie and then Ted came down the ladder to where Annie and I were sitting. Lights and building started flashing by outside. I observed that we must be approaching civilization. Ted and Annie started to pick up their clothes to get dressed to go back to their room to prepare for dinner.

"Do you want to borrow our robes to go back to your room?" I asked. They both thought that would be great. Annie asked Catie what she was going to wear. Catie crawled across to the closet (nice view) and took out a black dress with a flowery pattern and showed her.

"And no underwear," Catie said (provocatively). She turned to Ted and I "No underwear, right!" We nodded yes. Annie was smiling at this situation.

They each put on a robe, gathered their stuff, and slipped out the door to walk to their room next to ours. I told them to knock on our door when they were headed to the dining car. The train was coming to a stop in Williston, North Dakota.

After closing our door and closing the curtain, Catie came up to me and gave me a big kiss and hug.

"How was it?" she asked.

"How was what?"

"How was Annie? How was it knowing I was fucking and being fucked by someone else right above you? How was everything?"

"It was very, very erotic. I wasn't sure what to expect. I found myself hoping that you were having a good time. I guess I have some sense of what it felt like for you when I've been with Jody or Abby."

"Do you or did you feel threatened by that?"

I thought about it a moment. "No, not really."

"Do you know why?" she asked. I had to say I didn't know.

"Because we belong to each other." Not that we belong with each other. That we belong to each other. What she said seemed right and true.

"What about Annie?"

"She's sweet...and limber. I hope we're that sexy when we reach their age. What about Teddy," using Annie's name for him.

"Oh, he's a teddy bear. Wants to stuff every bit of himself in me but afterwards wants to cuddle like a big teddy bear."

We each grabbed a quick shower and our conversation continued.

"You know we might end up with an offer to be in separate rooms, in separate beds later tonight. Is that okay?"

"What do you think?"

"I think it might be okay. But I'd rather we be all together. Let's play that by ear."

I got dressed with black slacks, a turtleneck shirt, socks, and shoes. No underwear.

I watched as Catie got dressed. A little eye shadow and eye-liner, mascara, make up, and a light red gloss lipstick. I always though that Catie looked good without make up. With it, it gave her a dramatic look. She dropped her dress over her head, adjusted it, combed her hair, put on some flat black shoes, and slipped a sweater over her shoulders. We were ready to go and were just waiting for the knock at the door.

"Let's sit across from each other. You sit with Ted, I'll sit with Annie."

"What if they don't want to do that?" Catie asked.

"We'll figure it out when we get there, then."

A couple of minutes later, there was the knock on the door. Catie opened it and asked "Ready?" Yes, they indicated. Catie stepped out and took Ted's arm. Annie commented that Catie looked like a young Natalie Wood. Ted agreed. I followed her out and took Annie's hand. "It's a shame what happened to her," referring to her death.

I pointed out that many of the scenes in her last movie Brainstorm were filmed in North Carolina near where I lived and worked.

We passed through the coach cars. We were definitely "dressed up" compared to the occupants in the coach section. I wondered what this might look like. Probably not like swingers. Older parents with their adult children? We continued forward until we reached the dining car. We were seated immediately towards the middle of the car. It wasn't full but it was busy. There was nobody sitting at the table across from us (yet).

We ordered wine and toasted to "new friends." I know I had the salmon for dinner and it seems like Catie did, too. I don't remember what Teddy and Abbie had. The conversation over dinner covered a wide range of topics including what I did, what Catie did, a bit more about where our families were from, and how we met. Most of it was presentable but we quieted down when things turned bawdy. During dinner, Annie and Ted gave us a more complete picture of what their swingers lifestyle was like. It wasn't an all the time or every weekend sort of thing and there were "rules." Who knew there were rules.

Their relationships were open in that there was no hiding who they were having sex with. Although they mostly interacted as couples, they could go off individually with someone in the group and that wouldn't be hidden. Sexually, they stayed within their group and in their case that was five other long-term couples of varying ages (assigned groups? No, just people you gravitate towards and had a natural affinity for). If they went outside their trusted group, they needed to reveal that and it was strongly recommended that they use protection with outsiders (like Catie and I). They even had sexual isolation times for sex with and without condoms.

Annie commented that the fact that we were prepared with condoms made things so much easier. Both Ted and I used condoms when we were inside the other's sexual partner. How about oral sex? There were rules about that, too but much more relaxed.

"So, you'll report that you had a sexual encounter with a couple of strangers on the train?" I asked.

"Oh my, yes, dear," Annie replied. "But we'll also report that we used condoms and that reduces our sexual isolation time." I found it fascinating that there were actual rules to swapping partners. Annie reminded me that she had been a nurse.

I asked if they had any encounters on their trip out to the west coast. Ted said they had a couple of prospects but they didn't pan out. "We don't push it if the vibe isn't there."

"I guess it was there with us?"

"Oh, yes," Annie said.

Catie announced (quietly) that talking and thinking about this made her very wet. She had Ted move closer to her and guided his right hand up between her legs under her dress. By watching Catie's face and eyes, I could tell that Ted was hitting the right spot with his hand and his finger(s). Annie guided my left hand between her legs and my left hand found her smooth pubic area and the wetness that she, too, was experiencing.

Annie asked/commented that it seemed like Catie and I had also shared partners before. Without revealing who those partners were, Catie admitted that she and I had indeed had several experiences with additional sex partners.

"Men and women?" Ted asked. I answered because it seemed that Catie was having "difficulty" staying focused. "No, for Catie and I, it's only been other women. Threesomes with Catie, other women, and me." I added "You're the first male / female couple that we've shared together."

Catie, between these little orgasmic contractions she was having, did manage to add that I had acquired much more experience before she and I met.

"Really?" Annie asked me.

"Yes," I said.

"Tell them about your 21st birthday. Tell them about Florida," Catie urged me. I gave them a quick synopsis of those experiences well before I was married.

I finished with "I was 19 years old and my grandmother was very happy to see me and spend some time with me at Christmas. And I was happy to see my friends. But I ended up in some very strange situations that I never imagined that I would experience."

"But did you like them?" Annie and Ted wanted to know.

"Yes. They were extremely erotic, the sort of things that would end up in Penthouse Magazine."

Annie commented that it would be nice if we could get off the train in Minneapolis and spend a couple of days with them. They thought we could/would have all sorts of fun including meeting "other friends." Catie and I shot interesting looks across the table at each other (Do we want to do this?)

I replied "As tempting as that sounds, we have people to do, and places to be. And I need to get back to North Carolina to see my son."

I paused for a moment and added "But, we're trying to get together at the end of January while I'm teaching a course in Denver. Maybe there's a way we can schedule a side trip to visit you, then." Chicago to Minneapolis was no short drive (over 400 miles) and I had done it twice before. The train trip nominally took the same amount of time as driving.

Then came dessert. I don't remember what it was other than having lots of chocolate.

"Catie has a dessert request."

Quietly, I told them about what Catie and I had talked about; that in our threesomes it had always been two females (that included Catie) being with me. Annie asked if I "allowed" Catie to play with the other woman or if Catie and the other woman were willing to play with each other without me. Catie and I acknowledged that was exactly the what we had experienced.

What Catie wanted was to have multiple male sexual partners at the same time. I asked if that would interest them as a dessert after dessert. Annie reached down to my crotch and felt it. "You seem ready for it." Catie, following Annie's lead felt Ted's crotch and reported that Ted seemed ready, too. Ted pointed out that it was too bad we weren't in adjoining rooms. That would make things "easier" for us (that was true).

It wasn't long before we were ready to leave (hot to trot was more like it). We left a tip for the dining car staff and walked back through the train to our sleeper car. The lights in the lounge car were dimmed as were the coach cars. Although Annie and Catie were walking in front of us, I could help but think that an attentive pair of eyes would have noticed our erections inside our pants.

We made a quick stop in our room to pick up a couple of personal items (like toothbrushes, toothpaste, and condoms) and then went to Ted and Annie's room. We crawled over the bed (which had but opened and made up for the night). The room was a mirror image to our room though it there was a slightly different shape. There was very little that was sensual about the way we got out of our clothes. We practically tore them off of each other to get naked. The curtains were all closed unlike the exhibitionist tendencies of Catie and I.

Since we were still in North Dakota and Catie and I hadn't had our anal sex interlude (we had shared that "goal" we had with Ted and Annie) we had agreed that we'd start with Ted in her vagina (with condom) and I would be filling her rectum (without a condom). Annie would be floating around the three of us on this "round." Catie put the condom on Ted while Annie was applying lubricant to me. She told me to save something for her.

I ended up being on the bottom on my back. Next came Catie. She slid me into her rectum from the reverse cowgirl position and once I was fully in her, she leaned back and got her legs running along side and outside of mine and then laid back on my chest. I cupped and squeezed the sides of Catie's breasts but it was Annie who was sucking on them while Ted was getting in position to enter Catie. Ted's knees were inside mine and I spread my legs further open (which opened Catie's legs even further) to give her more leverage to get into Catie. He had barely started penetration when Catie orgasmed...hard. Ted kept pressing into Catie during this orgasm and it didn't take long for Ted to be all the way into Catie, too.

Annie was still beside the bed coaching Catie through having two cocks inside her (though not much coaching was needed). Catie was saying something about being so full. Eventually Annie was leaning over Catie allowing Catie to suck her breasts. I brought my left arm and hand around so that I was fingering Annie. From my bottom position, I really couldn't do any vigorous stroking. Instead, I was feeling the pressure changing on the bottom of my cock (facing up) as Ted continued to stroke inside Catie. He wasn't going to last long and there wasn't going to be a simultaneous cumming of Ted and I inside Catie. That didn't really matter, especially to Catie. With a moan, Ted pressed into Catie and began cumming. I watched the "pained look" on his face as he started to cum and then the look of relief as each contraction forced more sperm out of him and Into Catie (though blocked by a condom).

He didn't stay in Catie long after cumming, carefully pulling himself out of her while holding the condom so that it didn't slip off prematurely. That left Catie laying on her back on top of me with my cock in her ass. I asked her how she was doing.

"Nice. Very, very nice," she said dreamily. After Ted finished cumming and pulled out of Catie, Annie was attending to him with the condom removal and subsequently taking Ted into her mouth while sitting on the edge of the bed. Ted was pretty spent and went over to sit in the chair.

Catie finally came out of her own dream state and told me that she needed me to fill her up and cum in her ass. She got up off of me, turned around so that she was facing me and slipped me back inside her rectum. A few minutes after we resumed, Catie waved Annie over to us and had Annie get up on the bed and sit on my face. I was now in a familiar position of having two women attending to me. I couldn't see it, of course, but I knew that Catie and Annie were playing together and figured Ted had a marvelous view of the three of us.

I was getting pretty close and Catie knew it from our experiences. I expected that Catie would lean back and invite Annie's mouth to her pussy as I was cumming in her ass but I got a surprise. Instead, Annie leaned back and lifted her pussy off of my lips and presented it so that Catie could lean forward and take Annie to her mouth. She maneuvered so that she didn't crush my nose while Catie's tongue lapped at her vulva lips and clitoris. As I got ready to cum in Catie, I slipped my tongue into the folds of Annie's anus and that pushed her over her edge. Moments later I was cumming inside Catie and as I did, the combination of my cumming and Annie's cumming while Catie held her mouth to Annie's pussy was all it took for Catie to go over her edge. We shuddered and shook to our mutually shared orgasm.

We were just recovering from this mutual orgasm when we arrived in Devils Lake, North Dakota. I noted that it was on our first trip together that Catie and I had our first anal sex experience while travelling through this part of North Dakota. Catie said that she had never imagined that anal sex would become an integral part of our sex life. This started a conversation between Annie and Catie about anal sex. Listening to the two of them "compare notes" about anal sex and having two guys inside them was very erotic. It got even more erotic as Annie described having even more multiple sexual partners inside her as we all sat around naked.

One of things that they shared about "age" was that for Ted recovery was longer between sex sessions. "Don't get me wrong," Annie said, "he can hold his own with our friends. But you young bucks can get hard and be ready at the drop of a hat," referring to me. They also attributed their active sex life to sustaining their active sex lives. Annie did experience a waning of her sex drive with menopause (more from not feeling well) but it picked up and maybe got stronger after passing through menopause.

I finally asked Annie what we could do for her now that Catie had gotten her "dessert." I expected her to request something similar to what Ted and I had done with Catie.

"You can do something for Teddy and I," Annie said. "With you permissions, of course," addressing both Catie and I.
