It's our 20th wedding anniversary this year so I thought that I would share with you all what happened on our 10th anniversary. My wife Beth & I (Paul) got together in 1996 and married in 2000, both of us having been married previously. Beth is a curvy size 10/12, 36C breasts, keeps her pussy trimmed and has a lovely bum.. I'm 5'9" medium build, a bit thin on top and shaved down below. We have a very active sex life and over the years have liked to try things neither of us has experienced before. However, although we enjoy the SH site stories, read the contact ads and fantasise about other people joining us, to fuel our sex sessions, there has been no indication that Beth would welcome the involvement of other people for real. That is until we went away to Fuerteventura in 2010 to celebrate our 10th wedding anniversary, both of us being 58 at the time. Although Beth had never gone naked on the beach (only topless) the days were spent on the nudist beaches viewing and discussing the various tits, arses, pussies and dicks on show and Beth’s cunt would always be juiced up and ready for a good fucking when we got back to the hotel. Anyway on the day of our anniversary we took our usual trip to the beach but when we got back to the hotel Beth said that, as it was our anniversary, I would have to wait for a shag ‘til we got back from our night out. We were going for a nice meal then to our favourite bar. It was a hot evening and Beth dressed in a loose fitting halter neck dress and as it was so hot I suggested that she didn’t wear anything underneath. By the time we had eaten Beth was somewhat tipsy and had been flirting with the waiters all evening. We then went to our bar, a small intimate bar off the main drag that played good 60s & 70s music. We got there about 10 pm. It was run by an English couple in their late forties called Cath & John. Cath was a curvy size 12/14 and always dressed to please the male customers; short tight skirts and low tops showing off her rounded arse and ample tits. John was medium build and very laid back. I think he enjoyed the way men ogled and flirted with Cath. It was quiet with only one other couple there who we had seen there before but not really talked to, and a couple of local guys. John said that it was always quiet on a Tuesday as it was a major ‘change over’ day. Cath introduced us to the other couple who were Vera and Rob. Both looked in their late fifties like us; Vera a shapely size 16/18 and Rob quite slim build. We sat at the bar with Vera and Rob talking about the usual mundane things, work, sport etc. The red wine was flowing and then as usual when tipsy Beth started talking the sexy things we had got up to. Informing all of the places where we had shagged and that she was naked under her dress. John said that it was clear that she wasn’t wearing a bra as her nipples were sticking up under the dress; however, he dared Beth to prove that she wasn’t wearing any knickers. I thought, even drunk, that there would be no way Beth would do that. We were sat on high bar stools and Beth turned to face Rob and briefly lifted her dress at the front to show him her naked cunt. Rob confirmed what I knew and John declared that that deserved drinks all round on the house. After all this excitement I had to go to the loo. On my return Beth was dancing with Rob to a smoochy soul tune. The two local guys had left and John then locked the door stating that now the party can begin. Rob & Beth were dancing very close and I could see Rob’s hand gently caressing Beth’s arse without any resistance from Beth. He was also pulling her hard against his crotch. My cock started to rise at the thought of what might happen. I was sat between Cath & Vera on a low settee and John was sat at the bar. No one was talking, we were just watching Rob & Beth dancing. The atmosphere was electric. John then joined them on the dance floor and Rob & John sandwiched Beth between them. John was clearly grinding his obviously hard cock into Beth’s arse crack. Rob turned Beth to face John and they locked into a deep passionate kiss. Rob then undid Beth’s halter and let her dress fall to the floor, leaving her naked apart from her high heeled sandals. Beth didn’t resist and was clearly caught up in the moment and I wasn’t about to object. John released his cock from his trousers and gently pushed Beth down until she was kneeling, then she slowly proceeded to suck his length. Rob in the meantime had stripped naked and then Beth began sucking on both cocks alternately. I was mesmerised by the scene in front of me and highly excited. However, I was distracted when two sets of hands started divulging me of my clothes and I was soon naked with two relatively unknown women taking turns in sucking my cock whilst in front of me my wife was doing the same to their husbands. Then John laid Beth down on some cushions and over the next hour I watched as Rob & John fucked Beth every which way whilst being encouraged by their wives to “give the her the anniversary fucking she deserves”. Beth was loving it. I had never seen her so charged up with sex. She was insatiable demanding that they fuck both her cunt and arse (she loves anal sex), the climax being when Rob slid his cock into her arse whilst she straddled John with his cock in her cunt. Her first real cock DP (she had fucked herself with a dildo once with my cock deep in her arse). Both guys then announced that they were going to cum, to which, Beth screamed obscenities telling them to shoot their cream into both of her love holes. John & Rob got up from Beth, both her cunt and arse were leaking cum. As soon as they moved away Cath & Vera moved in. Vera knelt between Beth’s legs and started sucking John & Rob’s cum out of her cunt and arse. Cath in the meantime was kissing and biting Beth’s tits & nipples. Beth was again in the throes of orgasm. I was still in a state of shock and excitement with a rock hard cock when, as Cath straddled Beth’s head forcing Beth to lick her. Vera said for fucks sake someone fuck my arse. I looked at Rob and he just smiled and nodded. Needless to say I was over to Vera like a shot and after lubing my cock up with Vera's pussy juice easily slid my cock into her tight puckered arsehole as she continued feasting on Beth. Unfortunately I didn't last long and erupted into Vera's arse. It must have been the heaviest cum since I was teenager. Everyone was spent. The women went to the loo to tidy up then Beth and I made our way back to the hotel in silence. The following day we discussed what had happened and both agreed that we had really enjoyed it at the time and had no regrets but that it wasn't likely to happen again, we did stay away from the bar for last few days of our holiday and to this day we have never had sex with anyone else (unfortunately).
