When I first met John, he introduced me to his sister Sylvia and her future husband, Mark. We always had good fun together being of the same age and sharing the same, sometimes naughty, interests. John told me about his long term sexual relationship he had with his sister. I didn't see any problem in it, because they only went to bed together for the fun of it; they weren't lovers. It all was based on lust they enjoyed both, having the opportunity.
So more than a year ago, one evening in bed, John told that he had spoken Sylvia on the phone. He had told her about our adventure with the birdwatchers. The two of them never had many secrets anyway, I didn't have a problem with his sharing as long as it doesn't concern our most private and most intimate talks we have together, and he keeps me in the loop. He told me they discussed swinging on the phone this time. It turned out that Sylvia and Mark got interested in swapping partners; Sylvia had heard about our adventures, and thought of us as possible candidates. The idea rose as both Sylvia and John would love to continue their sexual contacts, that is, if both of their partners would like to join in to swing together. She already discussed it with Mark and he was okay with the idea. Having always had an eye on me, he was enthusiastic about the possibility of having sex with me.
That sounded interesting to me too as Mark is attractive having a good sense of humor and a vivid, sometimes even a bit naughty, fantasy.
Both Sylvia and me used the pill, so we could easily arrange our menstruation not to interfere in our plans and we decided not to use any other protection.
To prevent other family members from finding out, we would have sex in different rooms, never discussing anything directly from couple to couple.
So, whatever happened in the bedroom, stayed in the bedroom, to be discussed only in the bedroom.
When we met we had a nice day and evening together, we didn't talk about the sex we have had with one another's partner when meeting up again the next day.
When it's time to go to bed, we wished one another goodnight and went to our bedrooms.
So, for example, in our home we arrange swapping very easy.
The only difference from normal was that Sylvia goes to our bedroom with John and I go to the other bedroom with Mark.
Both have a bathroom en-suite, so we meet another again in the morning to have breakfast together.
When with them we do the same; they also have two bedrooms with their own facilities.
When going to other relatives, we take rooms in the same hotel for the night, so we can do this on a quite regular basis.
Evaluating thoughts and conversations, John told me that Sylvia wanted him to guide her in enjoying a walk in the nude, exactly like I do.
We normally see one another again around 9:00 o'clock in the morning, when we are all well satisfied and dressed again for breakfast.
When having breakfast on Saturday together, John said not to worry if we heard them in the next early morning, as he was going to have a walk with Sylvia at 6:00 o'clock.
I answered: 'We won't mind waking up, as we will amuse ourselves and after that go back to sleep.'And that was exactly what happened the next morning; I heard a little noise on the stairs and some later closing the door of our garage. As Mark was still sleeping on his back, I went down. Sliding the blankets aside just enough to reach his dick and started to suck him. When his tool started to grow, he woke up and stretched. He caressed my head and ran his fingers through my hair.
To make sure he would do his duties before he orgasmed, I stopped sucking taking over with my hand and I asked him giving me my orgasm first by licking my pussy. We switched positions; I went on my back, spreading my legs and pulling them up, bending my knees to give him a good access.
He started teasing me, licking me in long strokes from my anus to my clit, but after a few minutes he started to do the works, putting his tongue as deep as he could in my love hole. Then he suckled on each of my pronounced pussy lips, pulling his mouth off with a plopping sound at each side before concentrating on my clit. In no time I orgasmed, but he went on until I pushed his head away as I couldn't stand it anymore.
Then he started to fuck me, and whispered in my ear that he wanted to come in my mouth. As this is a technique I told him about doing with John, I knew exactly what to do. He then fucked me until he reached his 'point of no return' saying: 'I'm gonna come.' Pulling his dick out of my pussy, he took his dick tight between thumb and index finger, holding back his cum until I was on my knees to receive him in my mouth. Right on time; he started to ejaculate in my mouth.
I swallowed his load and we lay side by side, totally relaxed, both in the afterglow of our orgasms.
Looking at the clock, I said: 'They must be on their walk now, I wonder if Sylvia will like it as much as I do. Looking forward to hear all about it from John..'
Mark responded that he was curious too. 'It's quite an exciting idea, I would love to see her walk in the nude next to John.' he said.
I answered him: ' The thought is almost as thrilling as actually doing it. Why don't you dress up; there' is still time to go there and we can walk the way in the opposite direction, as we always keep the most sheltered part for last.'
Mark said: 'OK', and stepping out of bed; he asked: 'And what are you going to wear?' as he saw me walking to the bathroom.
'That's what I'm gonna put up now; my make-up. For the road I'll put on a dress' I answered. In minutes we walked down the stairs, me wearing a short dress, flip flops and holding a towel in my hands like I always do going out for a walk like this.
In twenty minutes we were at the starting point and we saw our car. John had parked as always, driving onto the path backwards. Mark parked in front of it.
We both got out of the car, Mark opened the trunk for me, I undressed, and when everything was in the trunk, I said to him : 'To surprise Sylvia, why don't you undress too? It's not such a long distance for us, I calculated that we'll meet them within roughly ten minutes from now.'
Mark started to undress saying: 'That'll make the surprise complete; you're right!'
I told him to be fast, as I was getting cold standing still waiting in the nude. When he was done, he closed the hatch and locked the car. Having no place to stock the key of the car, we looked and found a good hiding place near the car under a stone and we went on our way.
It felt great as always, the fresh air all over my body. The cool soil on my feet making me feel extra naked.
Taking his hand, I said 'Mark it's better to try to relax and enjoy the walk'. I distracted him from what we were doing by saying we had marvelous sex before leaving, talking about that, I saw his dick started to swell.
I said: 'I consider it a compliment you're getting a hard on thinking back to our playful activities before!'
Mark answered: 'Yes, it was great; we should definitely do that again! It was so hot changing fucking your pussy to ejaculate in your mouth, your pussy-juice still on my dick when you savored my cum...'
I answered: 'I enjoyed it intensely too, tasting the mix of our juices.'
Oh, how I enjoyed inhaling the still fresh morning air while enjoying the scenery. I told him that we probably would meet John and Sylvia near the picnic table he had heard about. During our walk and conversation, Mark started to relax. After some ten minutes we passed the picnic table, so we knew we were close to our partners. And yes, we saw movement ahead!
Afterwards John told me his sister froze exactly like I did under the same circumstances; realizing she had to accept that she would have an encounter with other people being totally nude and vulnerable passing them. They had passed the 'point of no return', not in the sense like us before, but there it was. She simply had to continue if they wanted to be back at the car in time, before risking meeting larger groups of pedestrians.
When we actually saw them, it wasn't even clear one of the persons was naked, it might have been clothing in flesh color, but the silhouette didn't fit. Coming closer it was soon clear what we saw, by that time they must have seen that with us too.
We stopped and waited for them to come to us; Sylvia, relieved as she saw it was us, was the first to speak; 'Hey guys, what a nice surprise! Mark, Joan, what a great view. The two of you, like Adam and Eve in paradise! You two look so sexy naked together, and Mark, look at that dick, all swollen, it's a great sight seeing that; it obviously turns you on as it does me and Joan too!'
John said: 'I'm starting to feel a bit awkward all dressed between the three of you naked!'
I answered: 'That's something you can change yourself! We heard you leaving and at first we prepared ourselves,' I winked at Mark, 'to go to sleep again, but we realized we were still in time to surprise the two of you, and to give Sylvia the thrilling experience of meeting people. So here we are.'
Now Mark said: 'Let's finish the walk, I think we might have an interesting morning at home!'
He was right, so we went back to the cars, where we dressed and went home.
Back home we started the coffee machine to discuss where we stood. Of course things had changed, but that didn't mean there was no way to cope with that.
First we had a cup of coffee and John took the initiative saying: 'I think today must be an exception. I think we should continue to carry on like before, all being happy.
But for now it's very tempting tasting the forbidden fruit, let's have fun together, forgetting about it, starting Sunday in the evening when we go to bed.'
We all agreed and John said: 'Although it's early, let's toast to that.'
Everyone agreed to that; luckily, we always have a bottle with bubbles in our fridge for such occasions. John opened it and poured four glasses. When we all had a glass in hand, we toasted on a 'Perfect Sunday.'
Sylvia started to undress, saying: 'Let's party!' We all followed her good example before emptying the bottle together.
Before all heading to the room John and Sylva slept in, we took a shower for a fresh start. John and Mark organized new drinks; we all went for white wine.
Once we were all on the bed I broke the ice, asking: 'Are you all OK starting forming a daisy chain together? I always wanted to try that out, laying in a circle on our sides to warm up a bit.'
