Hi I'm Steve, approaching 50 and my partner is Sarah, just passed 45. Quick resume, I'm divorced my first wife changing career and then husband in some sort of midlife crisis 12 years ago and Sarah divorced having left her husband about 8 years ago no=one else involved they just didnt love each other any more and are now better friends than they were partners. It took a while but we're back on our feet emotionally and financially and have been together about 5 years. We generally mix with slightly younger couples , I swim,cycle, shoot, scuba dive and will try most things, Im no super fit gym addict but I do ok i think, neither of us are old duffers yet! We had discussed sex openly to save time with embarrased fumblings when we first met and we're both open to trying stuff but only between us, swinging came with too many worries about guilt/jealousy etc so it wasn't for us but we enjoyed reading about other peoples adventures.. Little did we know! We went on holiday to Cyprus in a complex with semi detached bungalow style apartments. On arrival I peer over the half height wall and see our neighbours, a chap about 40 (Simon) and a girl (Jane) about 25, it turns out later shes 36 but first impressions etc, in my defence I wasnt concentrating on her face!! We say the usual Hello and pleasantries, job done. The next morning I'm at the Dive center and who turns up but Si, also a diver. We go out on the boat, get briefed by staff and start preparing gear. I'm a qualified Dive leader so was ready in no time,Si turned out to be inexperienced and I had to give him a hand. He asked if he could buddy pair with me during the dive and off we went. Over the next few days we all got really friendly, Diving in the day and meeting the girls on the beach later. Sarah will go topless if its somewhere quiet but is a bit self concious of her 34E boobs, no such concerns for Jane,her tops off super skimpy bikini bottoms on, oil on and shes running around the beach, in and out of the water, everything. She couldnt match Sarahs boobs but had a great figure, very athletic and tanned and her bikini wasnt leaving much to the imagination. One night after dinner and a few drinks we're sitting together on two sofas opposite sides of a coffee table, chatting n chilling with our arms round our girls. I've got my fingers just into the waistband of Sarahs shorts and Si's doing the same with Janes little skirt, it wasnt anything smutty just relaxed stroking the lower part of her stomach as we chatted. The girls are leaning against us and I think Jane was nodding off a bit as her knees drifted apart and Im looking straight at a transparent pair of panties and her pussy, shaven apart from a thin arrow shaped tuft of pubes,soon to be joined by Si's fingers just creeping into view around thetop edge of her panties . She wakes up, closes her legs quickly and they make their excuses and leave. We go to bed but can't help but hear their enthusiastic love making next door. Sarah says 'Did you enjoy looking up Janes skirt?' My brain is screaming 'deny it' but I know theres no way out there! 'I was trying not to look but I couldnt help it' was the best I could come up with. 'Her pussy looked quite pretty I thought ' says Sarah. Where did that come from? Did I hear right? I managed a dutiful 'Not as nice as yours dear' before we made love and drifted off to sleep. The next day between dives I asked Si if they were into the swinging scene, I dont know why it just sort of slipped out. He replied 'Good god no, what makes you think that?' I apologise for being rude but explain that they seem so open, confident, touchy feely etc hope no offense. It turns out theyre like us, like the stories but have opted out because of fears of spoiling what theyve got. Everythings good until that night after a few drinks and we're back on the sofas only Jane is next to me and Sarah next to Si. Si says 'this pair thought we were swingers' and they both fall about laughing and the chat goes towards sexy stuff. They like the stories as well and Si says 'The girls are always drop dead gorgeous', 'And the boys can do it for hours' says Sarah. 'Well' I say 'We got the girls bit right n I can think about it for hours if thats any good, we just need the 10'' dick they all have. Its not me so it must be you!' 'OOH give us a feel' says Sarah and playfully shoves her hand up his shorts leg. To be fair he put up a spirited defence for a couple of minutes till she gave up saying 'spoilsport', Her breathing was a bit heavier from her efforts but she left her hand resting on his leg. He then says ' you wouldnt let me goose you with your partner watching would you?. Sarah put her feet on the cofee table and said'might do' and popped her knees open and shut a few inches,'oops missed your chance' laughing, then she did it again a bit wider, 'too slow haha, loser' Then she got overconfident and mistimed it opening her knees wide just as he made a lunge at her. His hand shot right up her skirt as she slammed her knees back together, she went absolutely rigid and the look of surprise on her face was priceless. Si tried gently pulling his hand back but he was trapped until she relaxed a bit. When she did start to relax she gave a little gasp, grabbed his forearm and looked at me, I knew that look, it meant 'oh no, I'm going to come soon', like any red blooded male he'd copped a feel while he had the chance. We'd been sitting there like a pair of idiots watching this until Jane says 'Are you holding out on me? and starts delving down the front of my shorts, I'm trying to reach around her to her pussy and still watch Sarah. Shes still holding his forearm but slowly lets her knees fall apart, I cant believe im watching Si wriggle his fingers into her panties and shes given up the shorts leg approach with her free hand and is going down the waistband! After a while of what I'd descibe as 'heavy petting' all round Sarah n Si are moving round to a 69 as do we. I remove Janes little panties and come face to face with the most heavenly pussy I've ever seen. I lick the soft skin along one side of it, back up and down the other side of it before slowly teasing down the middle, gently suck her into my mouth, hold her clitty with my teeth and swirl around it with my tongue, she goes off like a pop bottle covering my face with her juices. As we calm down a bit I look across and see Sarah still astride Si's face but sitting bolt upright and hes holding his cock at the base of it like hes trying to strangle the life out of it. Its the first time I'd seen it and was a bit relieved to see it was similar in size to mine, a long elegant head on it rather than my fat bulbous end, different enough to be interesting but similar enough to not be a threat if that makes sense. After a few minutes the girls move and sit on our cocks, Si came very quickly and I didnt last much longer. Later in bed we relive the event. Sarah had no intention of being touched by Si but as suspected had mistimed her teasing. When his hand touched her panties she instintively shut her legs but was mortified to then realise how wet she'd become which is why she went so rigid. I was right about him copping a feel but that nearly drove her over the edge. When she'd seen Jane going after my cock she thought she'd cop a feel as well and evrything went way further than intended from there. She told me that she'd sat upright because Si had dribbled a bit of come before he could strangle hold his cock and control himself and she'd swallowed it because it was only a bit and there was nowhere else to put it. Ice cream Brain Freeze time.. She hated the thought of slimy come in her mouth and almost gagged at the suggestion of swallowing it, she wouldnt do that with me but had just done it with someone else!!! Shit shit shit, this is what I'd always feared, stomach churning jealousy, she knew that I regarded oral sex as the most intimate thing two people could do, more loving than just sex. In a small voice she said 'Im really sorry'. I frantically rationalised it in my head. 1 She loves me, 2 She could have said nothing I'd never know 3 She'd got off his cock asap 4 What else was there to do with it but swallow, we didnt get prepared beforehand. 5 Its not her fault. We're good. 1 Hes tried to keep control by choking the life out of his cock 2 He hasnt treated her like a slut dumping a bucketful in her face 3 Hes returned the favour, licking her to orgasm 4 He hadnt abused the privelege hed been given. We're good. I said 'Its ok, I know how hard u can be to resist, he's treated you with respect, and I love u even more for having enough faith in us to tell me' We had the most wonderful slow fuck after that. The next day like manly men do, we very adultly avoided all mention of the previous night, the girls on the other hand had a full debriefing session!! The only reference to it was as we were about to roll off the boat when Si said 'You won't leave me on the bottom will you?' I replied ' No mate we're good, you can trust me.... its the sharks you cant trust' and im gone over the side. I couldnt help giggling to myself throughout the dive, there are no sharks here but I'm sure he kept checking over his shoulder just in case!!!!
