I’m Greg, I’m 28 and married to Tina who is 23. We have been together for 5 years and married for just over 1. We have a great sex life but have never done anything like swapping or stiff like that so what I’m going to tell you is hot for a load of reasons but one big reason is that it happened at all as Tina is usually so shy. I need to set the scene or it will sound way to weird. My father is originally from the states where we sill have family, now remember, my father was adopted so no blood family ( that makes this a little less weird). We all go over there about once every couple of years but Tina and I go every year to visit and have a great inexpensive holiday. We stay with my Uncle & Aunt, my dad’s sister ( no blood relative remember). Toby is 61 and Melanie is 55. They are larger than life characters and by larger than life I mean personality wise, physically they are amazing. Both of them are physically fit, they run marathons and even have a gym set up in the house which has its own pool and hot tub and stuff. A big secret I have is that I lost my virginity to Melanie and until all this happened I assumed Toby didn’t know but it appears that it was his idea bit that’s a side story. Toby is an outrageous flirt, he flirts with Tina outrageously which to begin with embarrassed her but she go used to it and started teasing him and flirting back. Tina is 5’8” has a decent body, is trying to lose a couple of pounds but is still how, her breast are nice and big and she is very pretty, all of this is noted by Toby. This last holiday Toby and I are on our own when he tells me how hot Tina is and that is she wasn’t my wife, then he stops and says ‘wow’. I said ‘ you know you’re a dirty old man right’ to which he replies ‘I’d love to be a dirty old man with her, she could make this old man very happy’. I told him that Mel would kill him if she knew which is when he told me that he knew that I had shagged her but that it was all good and that it was him that made it happened. I wished the floor had opened up I was so embarrassed but he kept on that it was fine and needed to be done and was his idea. He even said ‘ if you wanted some extra action I know she would oblige’. The rest of out time together was quiet. I had already told Tina some time ago about me and Mel and to begin with she thought it was weird and was a bit jealous but soon got over it. I told her about what Toby had said and that if he made her feel uncomfortable to just let me know and I would talk to him but her reaction was classic. My usually shy Tina was actually excited, I asked her if she thought he was hot and her reply was exactly this’ if we weren’t together, I would go on my back for him as soon as he asked, he can have me whenever he wants’. I was so shocked I was speech less for the first time in my life. This comment resulted in a long conversation about sex and the difference between making love and a good shag. Tina assured me that she was just fantasising and that she would never do anything to upset me or put our marriage at risk and I said ‘but you would fuck him if you could?’ She looked at me a nodded and giggled. I would expect that sort of comment to make me jealous but instead I found it so fucking hot it gave me a hard on and that night Tina and I fucked and I told her to pretend I was Toby, the sex was amazing with Tina having the longest orgasm I have ever known her to have. When we had finished I told her that Toby thought she was hot and that I suspected that he was desperate to fuck her, she told me not to be silly but I told her I was serious. Then I paused and said ‘ like you said, there is a difference between making love and just shagging someone’. So I decided to put it to the test, I made comments to Toby about Tina and I shagging and how good she was which he lapped up. Then I asked him if he and Mel ever skinny dipped in the pool, he said they did but only when they where on their own, I told him he was getting old. He asked if Tina would be into that and I just told him that the only way to find out is to suggest it. That evening when it was dark and the pool was lit I suggested we go for a swim, every one was up for it ad we got changed. Tina wore a tight bikini, her breasts straining at the material and seemed that they were going to burst out. We all jumped in and as usual Toby was flirting but now Tina was just as bad. Then Toby suggests we get naked, Tina screeches and tells him that he’s naughty but Toby’s shorts are thrown out of the pool followed by mine and then Mel’s stuff. After a few minutes Tina gives in and her bikini follows our stuff. She is giggling and screeching and jumping up and down letting us ( and by that I mean Toby) see her fat tits and her big dark red nipples. She hugs me and I get a hard on with the feeling of her breasts against my chest, she whispers, asking me if I was ok and asks ‘what if he tries to fuck me’ I simply said ‘ I love you so much, just pretend I’m not here’ . Tina floats away and for the next few minutes there’s some tickling and stuff and Toby picks her up and throws her around which causes a lot of laughter. Mel gives me a hug and I feel her hard as nails nipples on my back. Then I look over and Toby has his arms around my wife, they are talking and laughing, her big breasts pressing against his chest, then he lifts her up with one hand and takes her breast in his other hand and squeezed it, I can make out her nipple between his fingers and then he put his head forward and he puts as much of her breast in his mouth as he can and has a good suck. Tina’s eyes close and she puts her hand on the back of his head and holds him there. He sucks her fat tit for ages, then he lowers her. Tina takes a deep breath in a lets out a load prolonged grunt, looks at Toby, her eyes like saucers. She throws me a quick glance and then her tongue disappears into his mouth. My wife has another man inside her. With her legs wrapped round his waist Toby walks Tina to the side of the pool and I watch some gentle rocking as Toby starts to fuck my wife. Her groans are pretty deep and long, Toby manages to fuck her and suck her big tits at the same time. I was both gutted and turned on, my shy Tina now has another mans fat cock inside her and she’s having fun. Mel reaches round and takes my cock in her hand and starts to toss me off so I turn round and finger her pussy. We walk to the end of the pool, I lift her up so she’s sat on the end, open her legs and eat her shaved cunt. From that I manage to get her tit in my mouth whole and give her a good sucking before I lower her back into the pool and slide my shaft into her surprisingly tight pussy. Toby and Tina have got out of the pool, Toby has put a sun bed mattress son the floor where Tina is on her hands and knees. Mel’s holding onto me tight, her hard nipples pressing against my chest with my cock deep inside her, she’s letting out little gasps every time my cock slides back in. But I’m mesmerised by what’s happening at the other side of the pool. This 61 year old ‘uncle’ of mine has my wife on her knees and has pushed his fat stiff shaft into her and is slowly fucking her. Tina is groaning almost in a trance, her big tits swaying each time his shaft slides deep into her. Mel pulls her head back and looks over, ‘ let’s join them’ she says. We get out and grab another sun bed mattress and place it head to head with them. Mel gets on her hands and knees and I slide my cock back into her. Mel and Tina are now face to face, at times when our rhythm is in sync their faces almost touch the two of them groaning. Mel lowers herself onto her elbows and reaches forward and take one of Tina tits in her had and pinches her nipple between her fingers. Toby slaps Tina ass and tells her to get onto her back, she obliges. Now my wife is on her back, her legs open wide and he’s fucking her missionary style. Mel crawls forward and for a few seconds my dick slips out but out of breath she looks back and tells me not to stop so I’m slide back in. Now Mel’s face is over Tina’s and I watch then staring at each other not saying a word for ages. Then Tina lets out a cry and says to Mel ‘ he’s so fucking big, I cant’ believe how deep inside me he is’ Mel giggles and ask’s her if she’s having fun. My wife replies ‘ oh fuck this is good, I’m going to cum’. Then very quietly she asks Mel, ‘can he cum inside me, please’. I hadn’t thought of that, Tina’s not on the pill and I had to mention it but Mel gasps that she too him to the vet so he’s harmless which I took to mean that he has had a vasectomy. Mel tells Tina to let him cum inside her and Tina starts to groan and squealed thrusting her hips. Mel lowers her head the two of them open their mouths and exchange tongues. This was all too much for me and I start to cum, I bang Mel as hard as I can and fire off a load of cum filling her pussy. Mel lets out a grunt and I pull out but Tina and Mel continue to suck tongue and Toby keeps on going. Then he lays down on top of time and his shagging starts to get urgent, his big body covering my wife, his ass bouncing between her lags. Now Tina is grunting and screeching and then the two two of them go into a frenzy, Tina shaking, her head thrashing about and grunting and I know that means she’s cum. Toby thrusting again and again grabbing and squeezing one of her tits and I know that he’s impregnating my wife with cum. I sit looking at the two of them out of breath, my wet dick now getting soft. This was fucking amazing, Tina looks so hot, soaking with sweat playing with her nipple with one hand and his cum between her legs with her other. Then she manages to speak and looks at me and tell me ‘ that was amazing, fuck I can’t move’. Mel laughs and says ‘ that’s good’ and crawls to Tina’s side and plunges her mouth into Tina’s, the two of them going for it, tongues plunging into each other mouths. Toby sits back, his cock still solid. I thought we were done but Tina and Mel seemed to have other ideas. Mel shifts round and takes Tina’s tits into her mouth, first one then other before covering Tina’s pussy with her mouth. Tina lets out another squeal and is pushing her pussy at Mel. Mel looks up, her face wet with her husbands cum but she doesn’t stop and proceed to try and get as much of his cum out if Tina and into her mouth as she could. Tina is back thrusting and shaking. Then Mel crawls up Tina and plunges her cum soaked mouth and tongue into my wifes’ mouth. For the next 5 min I sit there and watch Mel grinding her pussy into my wife’s. Tina had never indicated or hinted that she had a lesbian or bi side so I’m shocked at how she’s going for it. The two of them now straddling each other grinding pussy against pussy tongues deep in each other’s mouths, tits in hands almost fighting. Then more orgasms and even that doesn’t end there. The two of them separate, Tina crawls onto the mattress that I had just used to fuck Mel, looks at me and begs me to fuck her. Mel and Toby are already at it, Mel riding Toby bouncing making her small tits giggle and bounce. I waste no time, my cock is getting stiff already, stiff enough to slid into my wife’s soaking wet cunt. We didn’t make love, we shagged like fucking animals, the noise of everyone squealing and grunting must have raise some eyebrows with the neighbours. In the end my cum splashed into my wifes pussy and mixed with Toby’s and Toby’s mixed with mine in his wife. For the rest of the holiday we did very little holiday stuff and mostly fucked. My wife being bent over the end of sofa’s being shagged by Toby, or me sleeping on my own and the others not getting up until late morning because they spent the night three on a bed fucking, (in fairness I had my share of Mel and Tina between the sheets). Tony wanted us to meet his friends but we drew the line at that, fucking them was over the top for us, fucking complete strangers is too far for us right now. Tina and I are saving like mad to go back for another holiday, we would like to go before my parents so we can have this experience again. If we do we will let you know.
