My wife doesn't' know I'm telling you our secret so I will change her name just in case. I'm 55 and my wife 'April' is 52. We have a very active sex life, we look at sites about swapping and dogging but had never done anything about it, I suppose we just never had the guts. my wife is very attractive and has a great figure. Because she has quite large breasts she gets a lot of attention from the guys. So onto my story. We found out that there was a dogging site near to where we where going on holiday in Devon. We talked about it for ages and finally decided to joint the site and we would go and see if it actually existed. We had no intention of doing anything, in fact we would keep our distance and just watch and see what went on. The evening arrived and it was quite mild so April was wearing a very nice summer dress which hugged her slim figure. We went along a bit later in the evening and so our surprise there was a lot of activity. It was getting dark but thanks to the car lights and some camping lights we could make out couples having sex against rocks and some oral sex by the side of cars. We found this very exciting so decided to go a little closer. After about an hour we where approached by a few lads who obviously wanted to have fun with April. I thin we both panicked and made our excuses and left. The next evening we felt a bit foolish and decided to go back, this time we wouldn't get so close. Again, after about an hour we got a little closer. Without realising it the same lads came towards us from behind. There where three of them, big lads about mid to late 20's but this time two of them had girls with them. We started chatting and as usual the guys couldn't take their eyes of April's chest. Now April is very opinionated and will stand her ground even if she's wrong which I love about her. They asked if we had done this sort of thing before and she was telling them how we where very experienced with this ( which was a lie). Two of the lads took her hands and started to lead her away. I started to make our excuses when the lads started to accuse us of being just old people who wanted to get kicks out of watching. before I could say anything April was giving him a piece of her mind telling them we where doing this before they where born. Before I could say anything she was walking off with them telling them that she would just like to watch thank you very much. The girls went off but the three lads surrounded my wife. I called to her to tell her it was time we left but she wasn't listening. She was watching what was going on. I went back to the car to get a jumper becouse it was getting colder and when I came back one of the lads was behind April kissing her neck. I know what this does to her and could tell she was going weak with this. I went to her and asked if she was ok and she just looked at me making a hand movement as though to tell me to move away. The other two lads just smiled at me. As I watched, the one kissing her neck unzipped her dress and let it fall to her waist exposing her bra which followed soon after. I my wife was standing there, her breasts exposed before being pushed against a rock. This lad was sucking her nipples whilst the other two started playing with themselves. She said something which made one of them grab a blanket from a rucksack. They had obviously come prepared. He put it over his shoulders also covering my wife. I could see him fumbling and kicking my wife's knickers to the side and then her eyes opened wide. This young lad was obviously inside her fucking her against the rock. I just leaned against a small rock and watched the blanket fall to the ground, my naked wife with a stranger inside her, his backside moving with each thrust, one other lad latched onto her nipple, sucking and wanking. A few people had gathered to watch and listed to them grunting, her large breasts swinging as she was fucked hard. Then he came inside her and she let out a great, deep groan, he grunted with each thrust, I guess he was cuming over and over. I thought that was it but as he pulled out another lad took his place and he fucked her as well and when he had finished the third lad moved her to a smaller boulder, bent her over and took her from behind. Her tits now free to swing with each thrust allowing some other stranger to have a squeeze. I remember thinking I should stop them but it was so erotic and she seemed to be happy, squealing and grunting. I'm not sure but I think he placed himself in her backside after slipping out and replacing his cock inside her and ejaculating. When the three of them had finished she just stayed there exhausted, one other guy moved towards her but enough was enough and I picked her dress up and handed it to her. She was out of breath as she put it on minus her bra and knickers which where no where to be seen. We love to talk about it, she tells me how fantastic it was to have one cock in her after another and I have promised that we will go back one day.
