Chapter 1

Ron and I have been married for three years now. We live in Denver and have made good friends with the couple in the next condo, Allan and Luann. They're about our age, like mid-twenties and well, we've gotten to know one another somewhat better than most neighbors.

About six months ago, we were at their place for a cookout after a swim, our condos have a really nice pool, and had begun our third bottle of wine. I think it was Allan who posed the question, "Gee, I wonder who's got the bigger boobs, you or Carlene?"

"You just want to see her boobs, I know you," she shot back at her husband who was sitting there with an obvious hard-on in his trunks.

Then, my hubby pops in with, "Well, I might just want to see Luann's. What about it girl's?"

Luann looked at me, shrugged and reached around and untied her top and let it fall.

Well, my friend next door had perfectly lovely breasts. Smallish C-cups, from the look of them, perfectly formed so nice and round with small dark red nipples. Luann was quite pretty to begin with and topless she could hold her own with any Playmate foldout.

They were now all looking at me so I did the same. Now, I'm pretty nice myself. Also with C-cups, they are round and full and each one points off to the side just a bit and I have those light pink puffy kind of nipples that always look freshly-sucked.

"Stand up together, the two of you," my hubby, Ron, suggested and Luann and I got up and breathed deeply, putting our boobs out front and center for both hubbies ogle us.

"God, aren't they gorgeous?" Allan said to Ron.

"So hot, both of them. I really don't care which one's got the bigger ones, I just want to play with them," my husband said.

Luann and I looked at each other, shrugged and we both moved closer to the two guys. They stood up and each one reached out for the other's wife's boobs.

I'm not exactly sure what I expected or what Luann expected but that's what took place; Allan was standing there in front of me, his hands feeling my boobs as my husband stood next to him feeling Luann's.

"Wow, really nice, Carlene, you've got yummy boobs," Luann's husband told me as he squeezed them gently enjoying them as I did as well. It might have been a bit unexpected but it was sure making me get wet.

Then I saw Ron bend down and kiss Luann's breasts and take one of her nipples in his mouth. Allan looked up at me and did the same. His sucks went right down to pull on my pussy. This was so sexy.

Look, I love my husband, sure, but to have another young, good-looking guy feeling and sucking your boobs, well, how could I not be affected?

"I think we should all get naked and have some fun," Allan suggested as he raised up off my nipple.

I, of course, looked at Ron, who shrugged and told me, "Well, I'm in if you are, hon," while Luann already had her bikini bottom off.

"Well, I guess we're in for a new level in our friendship, huh, guys?" I said as I pulled my bottom off as well.

Instantly, both hard cocks were out in view and, I must say, Allan had as nice as dick as Ron, long and straight, pinkish in color with a handsome, smooth, rounded crown on the end. They both looked about the same size, Ron is just under seven inches and Allan's was quite similar, in fact, it felt identical since I was now gently squeezing it in my hand.

Allan stepped forward and we embraced and kissed pressing our bodies together as our hands explored each other. Out the corner of my eye, I could see that our spouses were similarly occupied.

Everyone got acquainted for a bit before Luann suggested, "You two could take the master bedroom and Ron and I can use the guest room, if everyone agrees with that?"

There seemed to be no real discussion as each newly-paired-off couple retreated to our respective rooms. Allan pulled the covers off their bed and we both got on looking excitedly at each other.

"Well, Carlene, I've dreamed about this, actually, ever since I first met you. I am so up for this."

"Ever since we first met? I had no idea but knowing guys like I do, well, none of you surprise me, I think it's part of the male DNA," I quipped as our hands enjoyed each other.

I put him on his back as I turned around and swung a leg over his head. He was sure to know what it was I was wanting; it was what I always wanted with a new man as I lowered my lips down over his cock to begin sucking him while I dropped my pussy down for him to get to know.

As you might imagine, the atmosphere was pretty erotic and arousing, a new man, my next door neighbor, the two of us enjoying oral sex, knowing we would soon be fucking as would our spouses in the next room. Yes, even in the air conditioning, it was steamy.

As Allen licked and tongued me, I was thinking ahead hoping that we might make this arrangement a regular thing between both couples, yes, this was nice, very nice. I've always loved sucking a cock; it all started in the seventh grade with a boy I had a crush on, Anders Carlsson, a beautiful blond boy from Sweden whose father was running the huge paper mill on the other side of our town.

He had me to his house one afternoon after school and he asked me if I wanted to see him naked, that he liked being nude. It totally surprised me and I was even more surprised when I told him that, yes, I did want him to take his clothes off.

He was beautiful. Blond hair and eyebrows, light smooth skin and the loveliest penis I've ever seen, even to this day.

Once he was naked it was just minutes until I was as well. Then he had me lay down on his bed as he give me the first oral sex I'd ever had. Oh, it was indescribable so don't even ask me to try to tell you about it. Then he asked if I would suck him. Of course I'd heard about blowjobs, even knew you sucked and didn't blow. So, I got my first mouthful of semen and was on my way to many, many more. I just loved the ability to cause such pleasure in, at least from my viewpoint, such a simple and easy manner.

So, here I was sucking yet another penis, the first new one since Ron and I began dating, but I did sense that I'd maybe been wanting a new experience, someone different to have sex with. I guess you're not supposed to feel that way but, well, I admit I did.

Maybe part of that was the wonderful attention he was giving me down below. Ron often gave me oral sex, as I did him, but doing it with someone new is always arousing and, yes, I was very aroused.

His mouth was softly sucking on my clit as he finger-fucked me with his second and third fingers; I was not long from cumming. I knew I was just moments away when he groaned and I felt the warm spurts into the back of my mouth, a moment I always relish when my own orgasm began to mount, then swept over me like a wildfire out of control.

I was shaking and shuddering as wave after wave of purest ecstasy washed over me, it was wonderful, one of the best climaxes I'd had in a while. It was amazing what a new lover can do.

It seemed that being with someone new, even though our spouses knew we were together for sex, was enough that Allan, even after my sucking him off, still was quite hard so I flipped around and got up on him to ride us both to wonderful orgasms.

We fell on one another kissing and cooing telling each other how good our sex was and it appeared that both of us wanted to make our spouse-swapping a subject of discussion once we are all four back to together.

After a bit, Allan got up and went to see if Ron and Luann were still in their bedroom or back out in the family room. He came back and got me and we went back to join the others. The first thing I saw was their smiles. Evidently, they'd had just as good a time as we had.

"You two look pretty pleased," I commented as Allan and I came in the room holding hands. Ron and Luanne were on the sofa close together, her hand slowly stroking my husband. Yes, it was a bit odd to see another woman pleasuring my husband but there was no feeling of jealousy, just wetness and tingling in my own pussy as I sat in Allan's lap wiggling playfully over him.

"We all look pretty happy," Luann said and we all agreed.

"I think we should plan on doing this again," Ron said and we all instantly agreed.

Well, that made my pussy all warm and wet; now I had a new lover to look forward to, one who certainly just made me very happy.

"So, how did you and Ron meet, Carlene?" Luann asked me.

I looked over at my husband who was now grinning as he said, "Wanna tell 'em, hon?"

"Oh, this sounds interesting, maybe there's a story behind those grins?" Allan asked.

"Oh rather. It goes back to high school, well, for Ron, I was still in middle school, eighth grade, actually. It all started, well, it really started with my brother, um, and Ron's sister."

"Yeah, my sister and I, well, let's say we had a close relationship. Close enough that we were masturbating each other. Well, it turned out that I knew Carlene's older brother in high school and he brought her to one of our meetings."


"Oh, Ron left that out. It was the BSMBC, the Brother-Sister Masturbation Club at his high school. I know it sounds weird but there actually was a group of brothers and sisters who pleasured each other and they met every other week at someone's house," I explained.

"Wow, that is weird but pretty hot. You sure you two aren't kidding us?" Luann asked.

"No, it really happened. At one time there were seven brother/sister pairs in the club," Ron told them.

"I take it that no one took minutes or anything like that," Luann laughed.
