Sisters Find Out Mom and Dad's Secret

May and I were sitting at the kitchen table watching our combined five kids cavorting about the back yard playing in the water. We nervously exchanged the kind of talk, talk, talk we do for a while before she opened the big scrapbook Mom had let her borrow. It had been titillating me since she gave me a glimpse of it that morning.

“Well,” May said as she opened the scrapbook. “I had that talk with Mom last night. We were right.” She opened it to a five by seven picture of Mom and Dad with their friends, the Beardsly's. The nakedness didn’t bother me, our whole family has been active nudists since before we were born. It did shock me, though, to see that they were making love with the wrong people. Mom was riding Jim with his hands on her breasts. Dad had Maria on her back socking it to her. In the background were two other couples also going at it. My first thought was “ew” but we’d suspected this for years so it wasn’t really such a surprise.

May and I had been talking about the option of swapping spouses for quite a while. She had brought a magazine over a year or so before: Swapping Fun was a newsprint ad magazine with black and white photos and lots of ads for swingers. It had two very crude stories of swapping parties which we dismissed as pure fiction but which we found to be very erotic. We joked about swapping our husbands but never had taken it seriously, at least not too seriously. Brent is very cute and he does like to flirt. My nickname for Doug is “My horndoug” We never really took the thoughts very far in our conversation but it was clear that both of us were interested at least a little in being adventurous.

Our conjectures began in February. Mom and Dad aren’t very money oriented so May always did their taxes for them as soon as the W2s came in. Rummaging through Mom’s desk, looking for some medical receipts, she found a copy of 5miles. After Swapping Fun, 5miles was super sophisticated. The artwork was great and the stories were fantastic. A woman in one of the pictures, giving someone a blowjob looked a lot like Mom. No way, we thought. On the other hand, there were a couple of marginal notes in her handwriting reminding herself to call some of the people to set things up. May forgot about the taxes while she dug through the closets until she found a box with over a dozen issues. The two issues she copped kept us in erotic fantasyland for quite some time.

May is… well, she’s very blunt. She decided to visit Mom and show her what she’d found. By the time the kids got tired and had to have lunch we’d discussed that conversation several times. Mom and Dad were actively involved in a swapper’s club and had been having sex with other couples since he was in the Air Force before we were born. May got us both laughing when she commented: “It’s a good thing we both look so much like Dad.”

Fast forward through several weeks and dozens of earnest talks between May and me, Doug and me, May and Brent, Brent and Doug, and all of us with Mom and Dad. We’d finally gotten over the “eww” factor. It didn’t seem to be such a big thing when Mom talked the four of us into getting blood tests but afterwards there was a definite shift in our attitudes. She told us we should do it “Just in case” but it was very much a crossing of the Rubicon. May and I were definitely thinking that something might happen. Of course, Brent and Horndoug were all for making something happen. It took a lot more talks before May and I got over our insecurities and began thinking about actually doing something. The turning point came one Saturday afternoon at our nudist club. Billie and Eduardo, our friends about three years older than I am, had lunch with us with their two kids. Shortly thereafter, The Henderson's, about Dad’s age dropped in. Mom and Dad said that they were going to take all the kids on a nature hike then swimming afterwards. They said they’d be gone about two hours.

We all knew that the two couples were members of Mom and Dad’s club. For a while after the gang left with our parents, there we were, the six of us sitting naked around the living room of our double wide waiting for someone to say something. Slowly my gut began to tell me that something was happening. I felt confused, a little jealous, and unsettled but I also felt very positive about what I kind of knew was going to happen.

I don’t remember who started it but soon we were all talking a mile a minute asking questions and getting answers. Doug and Brent were wise enough not to talk much, leaving May and me to ask all the questions. At one point the guys went into the kitchen to find out the score of some game while we women continued to talk. At the time, I didn’t think much of the fact that when they returned, Brent sat next to me, and Doug sat next to May. Eduardo and Karl also swapped places. It seemed natural for our friends to put their arms over the women’s shoulders and massaging backs until I recognized that they were swapping. Then I realized when Brent put his arm over my shoulder that Horndoug was giving May a shoulder massage. The four of us looked around silently. May asked: “Uhhhh… are we going to….” Billie grinned and asked “Why not?” More silence then Eduardo laughed lightly and tried to put us at ease: “Look. You guys are obviously ready but not for everything. Let’s just explore a bit and see how comfortable we are.” Beverly added: “Group hug time!” so we stood and put our arms around each other for a while. Our friends began to get a bit frisky, fondling breasts. I felt a hand on my breast and Brent told me he’d always wanted to do that. It felt rather good. I got a tingle down the middle of my back and a little frog in my throat. I managed to tell him to go ahead. Telling him that kind of broke the tension. Of course I knew what was going to happen. We all had known that since Mom told us our friends were coming over. May and I had tacitly agreed and both of our spouses were on the track too. All we were really waiting for was for something to get the ball rolling.

Beverly got the kissing going. First there were pecks on the cheeks of the guys on either side of her. May and I followed suit. Soon the kisses were a bit more erotic, in keeping with the breast manipulation that was going on all around the circle. I gave Doug a big kiss then asked “OK?” He kissed me back and nodded. Then I kissed Brent and before I knew it we were pressed together kissing passionately, rubbing together. I really can’t trace my feelings, but being an artist they seem best described by their colors. They went from apprehension, a kind of a gray-blue background with flashes of yellow then acceptance and my feelings turned to a much more pleasant Prussian blue. Brent’s hands on me, the deep erotic kisses and his fully erect penis poking at me quickly turned my feelings to a bright, iridescent red with yellow undertones, almost like fire. That’s how my insides felt. A huge wave of incredible warmth suffused me as I nestled into Brent erotically for the first time. Horndoug and I had fantasized many times about swapping with May and Brent so this seemed an extension of those feelings. He was doing wonderful things to my boobs and he’s such a marvelous kisser. We went on and on and on, reveling in our newfound feelings together. I noticed Eduardo leaning back in the couch. Beverly was sitting in his lap facing forward while he played with her boobs. His erect penis was sticking out from between her legs as if it were her penis. What a rush I was getting.

When she reached down, moved her hips about and inserted it into her vagina my feelings went wild. Brent was driving me crazy with his hands and his erect cock poking at my tummy. Seeing Billie riding Karl on the floor like a cowgirl sent me over the top even more. Then I saw Horndoug and May. A huge pang of jealousy was quickly chased away by Brent’s ministrations. May’s legs were wrapped around Doug’s waist as he pumped into her, kissing her and playing with her boobs. Brent maneuvered me down into the love seat and took almost the same position with me. All of my jealousy disappeared, replaced by more orange and red, like a sunset… no a sunrise. This was a beginning, not an ending. Brent’s kisses sent waves and waves of alternating heat and cold into me, all through me. Probing with his cock all about my pussy he asked: “May I?” I answered with a passionate kiss. I’d fantasized many times about this but when his penis began to enter my vagina it made all the fantasies pale in insignificance. For the first time in over eight years another penis was inside me. It didn’t take long… or did it? I don’t know how long we rutted together, his penis probing, exploring, doing things, wonderful things to my whole being. My tensions rose, I tingled all over, I got higher and higher until everything released all at once as I shook all over moaning and screaming even though we were still kissing. My feelings were totally indescribable.

Slowly I realized that he was still inside me, still slowly thrusting softly into me. At first it was uncomfortable, I was too overloaded but soon it was starting to feel good again. I pulled him into me more, as much as I could. This was too good to pass up. Soon I was rising and rising and rising again as we fucked and kissed and enjoyed this totally new experience… a new guy, a different guy… and all around us were others making love too. Seeing my sister riding on my husband’s cock sent me over the top again and I was groaning through another orgasm with Brent. Perhaps not as monumental as the first one but absolutely wonderful. This time I retained consciousness, overloading my mind with the images around us. I felt Brent’s excitement growing so I began milking his penis with my pussy muscles. Why didn’t I think of that before. It’s fun to play with a cock with my muscles like that and it took no time at all before Brent was pumping his fluids into me over and over as he groaned and shook through his orgasm.

We rested, fondling each other for a while. After some time Billie asked us what we though of what had happened. May grinned from ear to ear: “I think we’ll do this again, right Sis?” “You Betcha!” I responded. We talked for quite some time about how we would continue with this new experience. We did another group hug, perhaps not as sexy as the first one but much more comfortable with lots of touching and kissing. We shared some more lemonade in the kitchen while we continued to talk, unable to keep our hands off of one-another. I got to play with all the guys’ cocks, comparing them for size and shape. Soon all the guys were up and locked again. Beverly asked whether we could have a circle. “What’s that? I asked?”

It’s kind of a tradition in the club. After the playing we like to share with everyone. The guys go around the circle screwing all the gals. May and I looked at each other then at our husbands. “Why not?” We asked in unison. Trooping into the bedroom all the women laid on their backs on the king size beds. We started with our own husband’s familiar penis inside us. We shared some kisses and some fondling as well as some sexy comments. It felt good to have Doug inside me again. He knows how to excite both my clit and that really sensitive spot just inside my vagina at the same time. About the time I was just getting into the mood Karl said “Time to change partners now.” I felt a real loss as Doug reluctantly pulled out of me and gave me another kiss. Not to be left out, though, soon Eduardo presented his larger, thicker penis to me. I took it with just a bit of trepidation but quickly guided it into me. The combined juices of my pussy and Brent’s semen let it slip in with hardly a pause. Soon I was feeling my third cock of the day. The unique feelings of his thrusting and kisses quickly brought on another small orgasm and just as I came down, it was time for Brent’s now familiar appendage to take Eduardo’s place. “I could really learn to like this.” I thought. I was just beginning to rise again when it was Karl’s turn. Doing this all so close together gave me a chance to compare the feelings of all the different cocks inside me. I restarted my rise again and came very nicely with Karl and right afterwards he came inside me. I rather enjoyed feeling his orgasm after all of mine. I heard Brent come, then Doug. As I was relaxing with Karl’s shrinking penis still inside me I looked up with a start to see Mom standing near the bed. Resisting the urge to hide what I’d been doing I just smiled at her.

“Well, kids.” She asked: “We thought you’d have fun. Did you?” All of us said “Yeah.” “Are you going to do it again?” May answered: “and again and again, and again.” We all laughed our assent. “Circle?” She asked. “Yeah..” Responded Billie. We thought it would get them over any remaining reservations.” The four of us agreed that it had been a good idea. May ventured that I had trained Horndoug well. I thought a moment then told her that it wasn’t so much that anyone was better, but the unique situation and the others around sure does add to the excitement. She agreed that it was the differences that made it so good. My good ole Horndoug quipped: “Vive le difference.”

“Well, playtime is over, kids. It’s time to get cleaned up. We’ll be bringing the kids back in about ten minutes unless you want to meet us at the pool.”

“We all need showers now. We’ll meet you there and use the pool showers. Ours is too small for all of us.” May answered. Brent added: “We can open the windows and let some fresh air in to get rid of the whorehouse smell in here.” We laughed and after another group hug and lots of fondling and kissing we all wandered over to the pool. My double load of semen must have been visible had anyone looked but nobody said anything.

So that was our introduction. Our folks usually watch our kids when we go to club parties now but once in a while we’ll be at parties together. It still feels odd to see them banging other people… Hell, it still seems odd to see them making love together but we are getting over that. I surely am glad that May ran across that copy of 5miles that February afternoon.
