First of all some details of me and girlfriend(at the time). This happened when Jane was 18 and I was 26 years old. We had been dating for around 18 months and was talking about engagement and marriage. By the way we did get married and still are happy married. Sex wise Jane was not too experienced, whilst I was moderately experienced. We were fucking like rabbits during this spell of life. During sex I would suggest adding another man/boy !! Jane I thought this idea was a non starter. But she never said no outright. During the summer holidays we would choose a suitable destination for a weeks stay. I picked a very nice expensive in Cornwall. St Ives was the place to go to for sun sex and well any thing that you fancy. I had driven about 7 hours arriving mid afternoon and I was shattered to say the lease. Both of us were excited to see our room. We checked in took our cases to the room and then went to the pool bar. I got a cold beer and Jane a large gin and tonic. One soon became two and soon we were slightly drunk/merry. At the next table an older couple Pete and Joan were in their swim wear. Pete tanned muscular body really caught Janes eye. Joan had a very skimpy bikini, Her breasts just fitted in her top. They looked in their forties, actually found out the Pete had just turned 50 and Joan was 45. They invited them selves to our table and instantly ordered a round of drinks. Then 10 minutes later I got some more drinks...We must have been talking about 30 minutes, when we both noticed Joan was stroking Pete's penis ! The look on Janes face was priceless. Remember she was only 18 and had never experienced such openness in two adults. With the drink and my own erection I was a little out of control. I reached over to Jane and my hand on her upper thigh. At this very moment Pete almost ordered us to their room for more drinks. Walking back to the room Pete put his arm around Jane and Joan did the same to me. In the room I made sure that Jane sat next to me. Yet another round of drinks.. Pete and Joan sat opposite us. Pete's erection was peeping 0out of the top of his trunks. Soon Jane had his penis completely out of his trunks! OMG it was so big, well compared to mine. Next Jane removed her top and two great breasts were bouncing around. Jane got on knees and gave Pete a blow job. Pete did not last long before he shot his sperm out. I had never seen so much sperm in my life. Jane never moved but was transfixed on Pete's penis. I made a terrible excuse and left their room. Back in our room I tore off Janes clothes and fucked her so hard and fast. I think I came in 15 seconds. It was at that time the best horniest sex I have ever had. We were speechless for about 15 minutes. I broke the ice and said had that just happened to us! We had a shower together and my thought was I would love to watch Jane being fucked by that penis? I plucked up courage and said to Jane how would you react to Pete's penis inside you? Deadly silence. The to my total surprise she said hey why not were on holiday aren't we? That evening we had dinner in the hotel restaurant. On the next table to us was our friends! Well they joined us and more drinks were consumed. I cannot remember but we all ended up in Pete's room again. I could sense Jane was nervous. I asked Pete and Joan if Jane could experience Pete's penis? Jane looked daggers at me and said I was only joking about that! Joan said if you really want to Jane that's okay with me.. Pete looked very happy. Jane said I will try. Well I suggested to Jane to undress and sit on the bed. I had never seen Jane so nervous before, but then she was going to have a monster cock fuck her. Pete undressed. His body was impressive and his penis was amazing, standing firm upright and circumcised. Pete very gently tonged her pussy and made it a little wet . Then he managed his body so his penis touched Janes entrance, very slowly edged his penis slowly into her pussy. After about 10 minutes he eventually got all his penis inside her, then slowly at first started to pump her pussy. To see Jane being fucked was great for me, this old man probably twice the weight of her fucking her pussy. Jane who never was a talker during sex started to grunt loudly and to my amazement was telling Pete to fuck her, quietly at first then screaming at him to fuck her cunt. Pete came inside her, the came again, the again. When he pull out of her sperm came flooding out of her swollen pussy..What a mess sperm all over. Then Jane scooped some out of her pussy and drank it. My Jane became a whore. From that fucking Jane became my perfect woman.
