Joan turned sixty in January last year and at last we were both retired, weekends away, longer summer holidays. Just after retiring she had some cosmetic surgery, tits a little smaller, nice firm perky 32b and a little work on her tummy. She is slim and blessed with legs which are still better than many women 30 years younger and although a bit old for mini skirts, will wear slit side skirts, flashing her stocking tops, and in the summer go out in tight tops with no bra. She can still turn heads walking down the street. Over the years we have frequently had different partners and swapped with other couples, watched each other fucking or being fucked, but as we got into our 50's it tailed off. The main reason being that as we got older many of the others, how shall I put it, let themselves go, got fat and were frankly unattractive. We regularly swim and visit the gym and I think look OK and probably younger than our age. Joan is particular proud of her new tits, often doing the house work nude and likes to stand with her pussy pressed against the washing machine as it does the spin cycle until she cums. Watching her naked still gives me a hard on and I will fuck her, usually before she finishes. She gets aroused being fucked in the dining room in front of the patio doors, knowing that a young lad of around 19, in the house behind can see from his bedroom. Most nights at about 10pm she will be there, resting against the table, fingering her cunt, getting it wet and slippery before turning so I can fuck from behind, she gets off knowing he is probably watching and wanking and has said she would quite like his young cock in her given half a chance. For years we have spent our summer holidays in France and have sometimes visited the naturist beaches. As I've said, Joan was nude in the house often and when I suggested going to France for a month last June her eyes lit up, immediately suggesting Agde adding that she could be naked for 4 weeks and if its reputation was anything to go by she might get some cock. I was all in favour hoping I might get some pussy. Agde it was. A small apartment, not the most luxurious and really in need of up dating but all we wanted was somewhere to sleep and shag. The first morning we both went shopping, admiring the beautiful and not so beautiful bodies as we wandered through the complex. Joan has shaved her pussy for years but getting back to the apartment she commented on how many men were smooth, how nice it looked and how much nicer a shaved cock would be to suck. Out came the shaving kit and off came my body hair finishing with a long slow blow job. We spent the first few days, watching, seeing what was going on, not spending to much time in the sun, careful not to get burnt but it was a good opportunity for her to lie in the beach, legs open, just watching, flashing her snatch. We also noted that a few people walked to the far end of the beach and into what looked like dunes. On the fourth afternoon she went on ahead and I followed about 40 minutes later. We had arranged to meet further along the beach where it was quieter away from the accommodation and backed by the low dunes and scrub. As I approached I could see her laid on a towel, right at the top of the beach by the dunes, two young lads, who didn't look much more than 18 or 19 sitting with her. I was about 50 yards away as she handed one a bottle of sun oil which he poured into his hand then started to rub onto her back, the other lad did the same, both steadily working their way to her bum, where they lingered when she parted her legs giving them access to her pussy, before doing the backs of her legs. I slowed until I was about 10 or 15 yards away then sat on my towel watching as she rolled onto her back hearing her tell them they'd better do her front too. She glanced at me, smiling as they massaged oil onto her shoulders then they both took their time rubbing it into her tits, using fingertips on her by now hard nipples. They rubbed oil on her tummy, steadily getting closer to her smooth mound. My prick was hardening as she parted her legs again as they did her thighs until one of them brushed her pussy with his fingers. She raised her knees letting them spread her legs wider, at the same time reaching out taking a cock in each hand wanking them. They both had their hands between her legs fingering her cunt as she moved her hips thrusting against the fingers. There were people passing, some just glancing at them but a couple and several men stopped to watch her finger fucked, wanking the lads. I heard her cry out as she came and could see her tossing them off faster until they both shot spunk over her tits and belly. They chatted for another 10 minutes before they got up and left and I joined her. There were still splashes of spunk on her body and she hadn't closed her legs, her cunt still wet and gaping as she told me they were Dutch, then with a grin that we were meeting them in one of the clubs and we were all going to fuck her later. My prick was still hard and I suggested moving out of sight behind some scrub bushes where I fucked her. She had another orgasm and only told me after that she had been able to see a man wanking as he watched us fuck. We had a quick swim to wash the spunk off her before returning to the apartment. That night she got ready, wearing just a stretch fishnet dress to show off her tits and a thong. We'd eaten and had a few drinks before arriving about 11ish. We met them outside, payed our money got our first drinks from the bar. Joan danced with them and enjoyed being the centre of attention, particularly when she came back from the ladies minus her thong. She was already getting excited, her erect clitty poking out from its hood, her cunt starting to juice, her pussy lips parting as she sat between them, legs open, letting them finger her cunt. I don't know if it was the sun earlier or the music but I had a splitting headache and told Joan I was going back to the apartment, but it was fine if she wanted to stay and enjoy a good fuck, leaving her with her two young studs. The next thing I knew she was shaking me awake, at 9 the next morning. She had just come back and was still wearing the dress and thong. It was just as well she had the thong for the walk back. When she stepped out of it, spunk gushed from her cunt, dangling from her puffy fanny, running down her thighs, splashing on the floor. She pulled the covers off the bed, and just said "Fuck me" as she straddled my throbbing cock and guided it into her spunk flooded cunt. Grinding her pussy on my erection she rode me, rubbing her clitoris with her fingers, stroking her hard little nipples, squeezing her tits. We were both soon at the point of no return as she collapsed on top of me as shot my load inside as she came. She lay on top with with my softening prick still inside her. I said "How many times did they both fuck you then? It must have been a lot judging from the spunk". "Both" she laughed, "All, you mean. I don't think even those two young lads could produce that much cum". She then explained that not long after I'd left they'd also departed, stopped at a bar where they'd met four of their friends and she had gone with them and another woman to their flat. Once there she had been fucked next to the other woman on a bed. She was fucked doggy, sucking cock, swallowing some spunk but most was deposited in her cunt. She rode one cock, with one in each in hand and one in her mouth. When he'd cum in her cunt she'd taken two more. At the same time. She knelt on the bed in front of me, reached back, spreading her cheeks, and said "Does my arse look sore? It should. I was arse fucked twice, once with a cock in my cunt at the same time". She estimated she had been fucked at least a dozen times, maybe more as the other woman had fallen asleep, and thought that two or three other blokes had turned up during the night and joined in, as long as they had a stiff dick she was happy. All she wanted in the morning was to get some sleep ready for us both to meet them again on the beach that evening, commenting how much of a complement she thought it was that these young men wanted to fuck her even though she's sixty. I think this is getting a bit long so I'll stop here and continue another day if you want. But to suffice to say she has been even more of a slut in the year since.
