I'd been chatting off and on to a couple on SH, let's call them Nick and Liz for now... Over the last few weeks of lockdown I'd come across one or other of the couple online and we would chat and share pictures, getting quite heated at times talking about a trip to Studland beach and what we would get up to. The only issue with all of this is that my wife, Anna, although we had an unexpected MMF last summer and she had a bit of prior experience when she was younger she wasn't keen for me to go ahead and organise something. What she has said is that 'if something just happened' as with the MMF, she sould 'go with the flow'. On holidays overseas she went a bit further, insisting on fucking outside, on the balcony and so on, in the hope of getting caught by another couple. In bed, our sex talk would focus on a small number of scenario's; a photography session that turned into a MMF or meeting a guy or couple in a nude sauna, which we had been to a number of times in Germany. Anyway, back to the beach. After a few online chats Nick, Liz and I hatched a plan; Anna an I were due to be on the south coast in a few weeks so we agreed to set up a chance encounter on the beach. Nick and I exchanged texts on the days before and luckily the weather was very good, with record temperatures forecast for the few days we were away. As Anna and I walked along the beach on the first evening we talked about the nudist beach and whether we should try it out. We agreed that night to give it a go and as we fucked we talked about a sexy couple coming across us in the dunes and what we would do. I used the opportunity afterwards whilst Anna was in the bathroom to drop Nick a text and agree a time to meet on the beach the next day. He said they'd both have large union jack towels and indicated roughly where they'd be, texting me a google maps image with a marker added. Anna and I headed to the beach mid morning, still chatting about the sex talk last night. At this point I should describe Anna I guess; she is 5'10", a size 12, curvy with 34F breasts that are pert and pointy, with very prominent nipples. She keeps her pussy neatly trimmed with a distinct landing strip, I love a bit of fur. She is a blonde/mousy with long curly hair. As for me, I'm a rugby player type build, similar height and we are both around 50. As we walked along the fairly quiet beach I saw in the distance a good looking couple amongst the mostly pensioner crowd, the towels became clearer as I got closer and I know it was Nick and Liz. I led Anna to a spot nearby then and lay out our beach towels before dropping my shorts and quickly sitting down as I was starting to get a little excited. Nick and Liz looked over, briefly catching my eye and winking as we watched Anna remove her bikini top and then her bottoms. Occasionally, we both looked over at Nick and Liz and they did the same to us. As we went into the still very cold sea for a paddle Nick and Liz followed us and gave us a first proper look at them both. Liz was younger than us by quite a bit, still in her 30's with firm but large, pendulous boobs and a shaven pussy with prominent lips. Nick was around my size and his cock looked a little thicker and longer than mine in its semi flaccid state. The whole thing was pretty exciting and after a bit of creaming up with lotion and a bit of gentle touching and kissing I said to Anna; lets go into the dunes for a fuck. We left the beach hand in hand and again, I winked at Nick and Liz, the signal for them to wander after us in a few minutes and hopefully catch us in a compromising position. Minutes later Anna and I were kissing, me with fingers in her very wet pussy, her wanking my rock hard wet cock. At this point I saw them come over the crest of the dune and stop, watching from a few feet away, semi crouching as Liz wanked Nick's now hard cock. I beckoned them over with a hand behind Anna's back and fingered her a bit faster, making her pant and bite my lip, wanking me harder in return. As we broke our kiss, Anna's eyes opened and saw Nick and Liz crouching a few feet away. It was crunch time; what next? She continued wanking me as she turned her body towards them and to our delight opened her legs and showed her gorgeous wet slit to our new friends before dropping her hand and circling her clit. Our new friends edged closer and sat within touching distance before reciprocating with a similar show, wanking and fingering as they kissed. After several minutes Anna reached out and placed her hand over Liz's hand on Nick'c cock, he reaching out and cupping Anna's breat in his hand, piching her extremely erect nipples. From that point things escalated quickly, the girls changing places and hands everywhere. Anna and Nick kissed, she leant to one side and took his cock in her mouth, cupping his balls as he fingered her pussy and groped her tits. I wanked as I licked away at Liz's smooth mound, it was quite sight watching my wife getting off with another guys cock in her mouth. We rolled about and got into a position where it was abvious we were about to fuck. Nick slid his cock up and down Anna's wet slit from behind, me and Liz watching then mirroring before we saw the tip of his cock slide in fully. We fucked like this for a bit before Liz pushed me back and sat on my cock, me playing with her huge tits, Anna benot over so Nick could get into her from behind, her head on Liz's chest almost alternating between kissing me and sucking Liz's nipples. It didn't take long for Nick to come, he bucked as he withdrew, shooting a stream of spunk over Anna's back as I came inside Liz... We lazed about for some time after before reluctantly heading off in different directions. Anna and I fucked a few more times back at the hotel, exchanging texts and pictures with our new friends and agreeing to catch up again sometime. More to come on that if you are interested to know what happened next?
