Some years ago, my wife Jane (not real name) and I were in our early thirties. We went for a weekend away in our caravan and on the second morning it was obvious that Jane was feeling very horny as we lay in bed and she started to grope my cock. I have e.d. but still enjoy sex. Jane stripped off her nightdress and straddled me, rubbing herself against my naked chest. I was playing with her tits and pulling her nipples, which really turns her on. I used to say, “play with Janes tits and her legs fly open”. I moved Jane up the bed until she was sitting over my face. I immediately started to suck her clitty and she went into ecstasy. She leaned forward and opened the curtains at the window, which was open. She was moving up and down on my tongue and her tits were jogging free. She told me later that the young boy in the next caravan was outside and he looked straight at her. She held her tits out towards him and then beckoned him over. He came to the window and the first I knew of it was when his hand came through the window and started to fondle Jane’s tits. Nothing like this had ever happened to us before although, like most men I had often wondered what it would be like to see Jane with another guy. Jane was now really turned on with my tongue inside her and another man pleasuring her tits. At this point I had not seen who was outside so I suggested that she should invite him in. The door was next to the window and was not locked. It soon opened and I saw that her new admirer was in his late teens. He came inside and stood before my naked wife who was still sitting on my face. Jane took his hands and guided them to her tits and he was soon playing with her nipples. It was obvious that he was enjoying this by the bulge in the front of his shorts. Jane leaned forward and pulled his shorts down releasing a large rock hard erection. His cock was uncut and Jane had never played with a foreskin because I hadn’t got one. She began to slide it backwards and forwards as he thrust his body forward in ecstasy. I now moved from under Jane and she was there in full view and enjoying every minute. She took his one hand from off her tits and placed it between her legs and I watched as he put two fingers where my tongue had just been, I told him that he was free to do what ever he wanted as long as Jane wanted the same thing. He was now finger fucking her while she wanked his cock. I suggested that they should change places, that Jane should lay on the bed with her legs wide and put her hands between her legs while he kneeled on the bed between her legs and wanked himself. They did this for a while and were getting more and more excited. I then suggested that Jane should pull her nipples and he should rub his cock against her pussy. Mine was the only cock that had ever been inside Jane but she was obviously enjoying this young stiff cock rubbing against her. She was becoming more and more animated and she suddenly shouted, “I want it inside me”. He looked at me and I nodded my approval. I then watched as he lowered his body on top of Jane and I saw his cock disappear inside my wife. Janes legs soon closed around his waist as she pulled him deeper inside. He now had his mouth over hers and I could imagine their tongues dancing together. He thrust in and out faster as Jane let out a cry of sheer excitement she had orgasmed and a few thrusts later he was ready to come. He looked up to me for approval once more and I nodded. He then let out a cry of enjoyment as he off loaded deep within my wife, who had a look of complete satisfaction on her face. They soon parted and the young man pulled his shorts on and departed. We didn’t even know his name. Jane was very satisfied with the event and as payment for my approval she took my semi hard cock in her mouth and gave me the best blow job ever even taking and swallowing my load, which she had never done before.
