My wife and I are both 26. Kiley is short, about 5’5” , very pretty and slim with long black hair and I’m a little under 6’ so we are referred to by our friends as ‘the odd couple not just because of the height difference but because we click so well and both have the same outrageous sense of humour which is what started us on our sexual adventure. We live in a 2 bed house with a small garden (I will explain why this is applicable in a second.). At the end of our garden is a low fence and garden belonging to our opposite neighbours, Paul and Hanna. The distance between our houses is about 17’ so not long at all. Hanna and Paul are both in their mid-50’s, he’s quite a distinguished guy, grey since he was in his 40’s but tough looking. Hanna is ‘curvaceous’, nice hips, broad shoulders and big soft tits and like Hanna and I has a dirty sense of humour. Hanna and the wife (before the lock down) used to go out with friends a lot and would often come home steaming drunk but laughing hysterically. So, after about a year of living there Hanna was in our house and as usual laughing with my wife about ‘stuff’ when she calls me into the kitchen where they were sat and asked me if I liked watching her undress in the bedroom. I was horrified because I never watch her undress. She laughs and says, ok, do you like watching me undress in the living room, and again I protested my innocents. The wife and Hanna looked at each other and burst out laughing, it was clearly joke at my expense. Kiley then looks at me with her wicked grin and tells me that she bets I would love to see Hanna undress and tells Hanna that I would often comment on our neighbour has all the right curves. At this point I make a hasty retreat to save my blushes much to the delight of my wife and Hanna who can’t contain themselves. A few days later Kiley is calling for me, it sounded urgent. I run into he is living room which faces the garden, ‘look, quick or you’ll miss it’ she tells me. I run to stand next to her and look out of the French windows. Opposite us Hanna is slowly undoing a dress with a big grin on her face. I start to walk away but my wife begs me to watch so I do. Together we watch Hanna slowly strip, her dress unbuttoning in the front before she slowly opens it and lets is drop to the floor in slow motion. Hanna has a big grin on her face whilst my wife is giggling and commenting how hot she looks and to be fair, she did. Her breasts covered in what I would describe as French lacy bra were as big as I expected, her cleavage pushing out, her knickers where small and tight and for a woman in her mid-50’s she looked amazing. Then, as soon as it had started Hanna closed her curtains and the show was over. This went on for a few days with my wife eventually joining in and I would stand there and watch Hanna slowly strip whilst next to me my wife did the same, but quite often she didn’t wear a bra due to her small size so then her top came off she was topless. I could hear Hanna scream and laugh from our living room. I motioned for her take her top off, she started too but then closed the curtains before I got to see anything. Then one Saturday the girls sit out and have a little too much to drink and start talking about sex and comparing notes even down to how much my wife likes going down on me which Hanna thought was hilarious. They even compared my cock size to Pauls (who was in work and I assume didn’t know about the impromptu stripteases) using the Anglers measurement ‘I caught one that was this big’ which basically is bullshit and exaggerated which led to Pauls apparently being to foot long and too thick for Hanna to get her hand round and mine being a bit longer and thicker much to the hilarity of the two women. In the end the two of them go into Hanna’s house and leave me in peace for an hour until I get a phone call from my wife’ come to the window’. I do as I’m told and there, in Hanna’s big living room window my wife and her friends and stripping, music accompanying them, the two of them clearly pissed. I watch as my wife and Hanna strip until Kiley is just in her knickers and Hanna is in her knickers and bra. I motion for Hanna to take her bra off. There more laughter until my wife unclips Hanna’s bra and her big soft tits fall out. The two of them are giggling like schoolgirls. Hanna and my wife start gesturing for me to get my dick out for them to see. After a minute of pleading My wife turns to Hanna and puts her hand under Hanna breast and lifts it to her mouth still looking at me out of the corner of her eye and starts to kiss her breast before letting Hanna’s nipple rest on her tongue. Hanna puts her hand on the back of my wife’s head and holds her there whilst my wife starts to suck Hanna’s nipple. She stops and gestures to me to get my cock out, so I did. I take my t short off and step out of my jeans and start to slowly wank. He two women are hysterical pretending to be shocked until Hanna put her hands on my wife face and kisses her. The two of them trying to kiss and watch me at the same time. I toss my self off whilst I watch these two supposedly straight women sucking face and each other tits. Then they pull their knickers off the standing side by side masturbate, hands rubbing their clits whilst I stand there and wank. I watched my wife’s small tits wobbling and Hanna’s big tits sway and the look on their faces was amazing, so It wasn’t long before I came, shooting my load onto the French windows. I could tell that Hanna at least had cum, my wife just got dressed and I went to clean myself up. Kiley walks into the house and we just looked at each other. I was Kiley who talked first ‘what the fuck did we just do’ she said with a bug grin on her face. I told her that I thin I just had a wank watching your two having a wank. We laughed, sat on the sofa before fucking hard. We went to bed and fucked again before talking about what we had just done. I wondered what Paul would think about it, Kiley said that she thought Hanna tells him everything and admitted that Hanna’s fantasy was to watch her (my wife) on her knees sucking her husbands’ cock. We left it at that. Days later Kiley brings it up again and admits that her and Hanna had sucked face before that Saturday experience. I was shocked because she had never given me the impression of being BI or wanting to experience something with another woman, but she tells me that it ‘just sort of happened’. During sex Kiley was sucking my cock and I asked her if she pretended it was Paul’s cock she was sucking. She asked me if I wanted her too to pretend it was. I did and the sex was hot and hard. I imagined watching my wife on her knees with his cock in her mouth. She asked me to tell her what I was thinking so I told her. We moaned and sucked until I came in her mouth and she climaxed. We cuddled (after she brushed her teeth) and she asked me if I wanted her to do it. It was one of those, do you want to do it with a ‘do you want me to do it’ conversations which ended in us both agreeing that it would be dangerous but exciting. It was three weeks of normality before I get a call from Kiley who was late home from work telling me to look out of the window. In my heart I knew what to expect but not how hot it would be. I went to the window and saw my wife on her knees. She was naked, kneeling behind her and also naked was Hanna, her big soft tits hanging for me to see. I see someone move in the living room and slowly Paul appears, her naked also, his cock not quite the two feet long with a massive girth but impressive all the same. Kiley looks up at him as he approaches. He put his cock on my wife’s forehead and runs it down her face almost slapping her face with it a she cups his balls. I look at Hanna to has wrapped her arms round my wife and is pressing her big tits into Kiley’s back. They look at me I guess to make sure I’m watching, then Paul holds Kiley by her hair and slowly guides his cock into her mouth. I stand there and watch this other man very slowly fuck my wife’s mouth whilst his wife kisses her back and neck gripping Kiley’s small tits. I watch this for what must have been 15 minutes or so, Paul pulling his cock out so my wife and suck his balls whilst Hanna stands up so they can suck each other faces with my wife still on her knees, his balls in her mouth before he pushes his cock back into Kiley’s mouth. By now he’s fucking my wife’s face hard, Hanna behind her leaning back and fingering herself. I get my cock out and wank hard watching Hanna masturbate wishing I could put my cock in that pussy. I see Paul pull his cock out of my wife’s mouth just as a spray of cum her face and tits and its clear all three of them have climaxed. This happens three times over a week until it gets serious, we both talked about it during sex and Kiley assures me that her and Paul have not had sex and that all they do is what I watch and I believe her. I asked her if she wanted to fuck him, she looks at me and bites her lip and I have my answer. The next weekend we’re all set up for our, now semi regular’ dirty half hour. I’m thank full that none of our neighbours can see us from their homes. I stand at the window and watch my wife fall to her knees with Paul standing in front of her running his cock over her face before leaning down to grip her tiny tits, but Hanna is missing. I watch Paul sliding his cock into my wife’s mouth before pulling it out and I see her pleading with him. Then Hanna walks out and makes it over the small fence that separates out gardens. I open the French door for her and she walks in, takes her coat off and completely naked gets on her knees. I’m undressed in a flash and whilst I watch her husband start to slowly fuck my wife’s mouth again Hanna starts to suck me off. I notice how big her nipples are and want to suck them so much. She glances over to her husband and my wife which makes me look. Paul is on his knees facing my wife, the two of them sucking tongues and licking each other’s faces whilst he squeezes Kiley’s tits and she has his cock her hand. Kiley pulls back and looks down at Pauls cock slowly wanking him, she looks over at me and Hanna and I wonder. It was Hanna who initiated it. She lay on her back and opened her legs and pleaded with me to suck her pussy. By now Paul had already gone down on my wife who was reaching forward and gripping his hair to hold him in place which was a favourite thing of hers when we fuck. I go down on Hanna and taste her sweet cum juice. I can reach up and hold her tits whilst she thrusts her pussy into my mouth and moans and begs for more constantly thrusting herself into me. She screams out and pleads with me to fuck her. I look over at my wife. Paul has his arms under her legs pushing her knees up to her face. He’s in her, pumping away. My wife is fucking another man and clearly loving it. Hanna brings me back to the situation in hand and assures me its only sex. I enter her and fuck her hard. Hanna and I fuck whilst watching Kiley and her husband fucking, all four of us watching each other fuck each other’s partners and it was devastating and erotic and hot and upsetting all at the same time. The sex was hard and dirty. I convinced myself that I could hear my wife grunting and crying out and pleading for more whilst Hanna became a foul-mouthed fuck machine. I watched Paul shop before giving my wife a few more thrusts, I saw her face contorted and a look of terrible pain and I new he had cum inside her and made her cum hard. I emptied my balls into Hanna much to her delight. We all fucked once more before my wife came home and Hanna walked back to her husband. That evening my wife and I lay in bed holding each other, her pert breasts on my chest, her hard nipples pressing into me. We talked, I asked her to be honest and she was. She admitted that the feeling of another mans shaft in her pussy was exciting. She admitted that watching me fuck Hanna made her cum and that the feeling of Pauls cum pouring into her made her cum even harder but that there was no love there, that our sex was special. That was enough for me. We slowly made love before falling asleep. That was before that lock down. Now, we are careful. We know we can’t swap and fuck but are desperate to do it again. But now we have to be different. Twice a week with the French doors open if its warm Kiley gets on her hands and knees and I slide into her from behind and we slowly doggy fuck whilst Paul and Hanna watch. Sometimes they so the same and I watch Hanna’s big tits swing. Kiley and I talk dirty whilst we fuck and she has admitted that her and Hanna have done more that suck face. Whilst slowly pumping her pussy from behind, gently feeling her hard nipple I asked her is she wanted to fuck Hanna properly. She glanced back at me and trying to catch her breath told me that Hanna had fucked her pussy once and that Hanna was fucking another man and that my wife had gone with her and watched her fuck this stranger which is what led to her and Hanna having sex. I think my wife and I have a lot to talk about and we have to be honest. I am now sur that my wife has fucked this other man as well. I am going to have ‘the chat’ tonight and Kiley has promised to be honest so I will let you know if she tells me anything that I feel I need to report.
