Once again we rented a holiday cottage for me, Sophie my wife, Alex her brother and his wife Fran. Alex is OK but a bit of a drip and I get on well with Fran who, at 38, is 3 years younger than Sophie has a slimmer figure, small tits and a sexy little arse. The only problem was that it gave Sophie yet another excuse to avoid sex "in case they hear" which resulted in a whispered argument the first night. We had arrived seperatly on the Saturday and over the weekend had enjoyed the weather and visited the beach. On the Sunday night we got a phone call saying that Sophies and Alex's mother was ill and wanted them both to go home, 200 miles away. Off they both went on Monday morning leaving me and Fran. We went out for a meal in the evening and they phoned to say they didn't think they would be back. The next day was sunny and we went to the beach which was backed by miles of dunes. Walking back through them we heard a noise and stopped to look. In a sunken area were a woman and two men fucking her. I made to move away but Fran held my arm and said "Quiet. Lets watch". The woman was on her knees being fucked and had the other cock in her mouth. My cock was getting hard, I glanced at Fran and she was rubbing her pussy through her dress. We heard the woman demanding to be fucked harder and saying she wanted them to spray her with cum. She was swearing as she came and the men shot sperm on her back, face and hair. We realised they had known we'd been watching when two of them looked at us and smiled. We carried on to the the car and talked about what we had just witnessed. At the cottage the conversation turned to sex, Fran said "I heard you and Sophie the other night. When did you last have sex?" I was rather embarassed when I admitted it had been about 6 months. She just gave a grim sort of laugh saying "Same here. It must me a family trait. Alex shows no interest either". I looked at her saying I found it hard to believe as she was so attractive. She said "I get really frustrated. Don't you?" I said "Yes, of course. Then to my surprise she said "Do you masturbate?" I replied "Yes, do you?" "Yes, it feels so good". I was next to her and we kissed. We moved apart and we undressed. Her nipples were rock hard, as I put my mouth them and sucked, she stroked my cock. I kissed down over her stomach to her hairy pussy and knelt between her legs, parting them as I went down opening her up and licking her cunt. She held the back of my head pressing and grinding her clitoris against my tongue until with a gush of juices she came. She led me to the bedroom and said "I want you now. I want you to fuck me". She lay back and spread her legs wide as I mounted her and slid my prick in to her waiting cunt. She felt so good, wet and slick but tight as we fucked. Neither of us had had sex for months and it wasn't long before we both came, her accepting my spunk deep in her pussy. We rested then an hour or so later had a more relaxed less frantic fuck before falling asleep. In the morning she watched me as I showered and shaved and I was watching her shower when she asked if she could have a razor. I gave her one and the foam then watched as she shaved her pussy, helping her remove the final hair from around her cunt. She wanted to return to the dunes saying that she had always wanted to have sex outdoors and if she didn't do it now she probably never would. She put on a short dress with nothing underneath, laughing that Alex would have a heart attack if he knew. At the dunes we made our way to the spot we'd passed the previous day. It was deserted as we lay towels and Fran removed her dress. She laid down then parted her legs and started to rub her clit with her fingers. I undressed and got beside her kissing her and caressing her tits as she wanked me with her other hand. She was very aroused and rolled on top of me and still holding my cock guided it into her soaking pussy. We were both desperate to fuck each other again and going hard at it when she said "We're being watched". It seemed to make her even more excited as she leaned back stroking her tits and pinching her nipples. She was fucking me, shouting out for me to fuck her harder, as her cunt spasmed on my cock. She went rigid as she came and I felt my cock ejaculate my sperm in her cunt. She sat on top of me as we came back from the high and said "We're still being watched. I'm going to call them down". Before I could say anything two men were beside us. She reached for their pricks which were already hard and pulled one to her mouth, parted her lips and sucked on it whilst wanking the other. After a few sucks she turned to the other alternating between the two. After about 5 minutes she slipped my cock from her pussy and knelt in front of one who rammed his prick straight in to her waiting cunt. He was fucking her hard as she licked the others cock telling him not to cum because she wanted his spunk in her cunt as well. She was moaning and crying out for more, demanding to be fucked hard telling them to use her like a slut when she got his spunk in her. He pulled out and the second man was right in there fucking her with no let up. As soon as he penetrated her she came, juices and cum running down her legs. He held her hips tight and was forcing his cock as deep as he could, pulling out then back in hard. His strokes were getting faster, he grunted giving her his sperm. She collapsed on the towel and rolled on her back. Her legs spread, her cunt gaping open, spunk dribbling out and running down her arse. Seeing her laid there, fuck juices running out of her well fucked cunt was incredible. One of the men went down on her and licked her clean making her come again in the process. We were all hard again and before we left fucked her again. On the way back she said that we were certainly making up for lost time and I asked if she regreted it. Her only regret was not having done it sooner. We went back to the dunes whenever the weather was fine and on most occasions she was fucked and wanked over, one time driving to the cottage practically covered in cum. On the last night she asked if I'd ever tried anal sex. I hadn't but we both wanted to. She masturbated and got her cunt juices flowing and I lubrucate my prick with it. I used my figers and saliva on her arse and got her nicely lubricated before I rested my glans against her virgin arsehole. I pressed my cock against her and she slowly opened up as my prick slid in to her shit hole. She was wanking her clit as I fucked her tight arse, she came and I fucked her harder until I spunked inside her. Since the holiday we meet whenever we can and fuck. In the summer we went to a barbcue at their house and she gave me a blow job at the bottom of the garden with Sophie and Alex only yards away on the other side of a hedge. We have both been reading the posts on this site and hope to be able to get away together to a dogging location so she can be fucked by more cocks soon.
