I had moved house last summer and had been getting to grips with my new surroundings. i was very pleased to meet my new neighbours. To one side is a solitary man, divorced and though he passes the time of day, says little and keeps himself to himself. As he keeps his garden tidy and walks his jack russell twice a day, I have little to do with him. On the other side is a younger couple who are friendly and have quite full social lives, frequently going to see major stars if they can get tickets and are keen to tell me their exploits over a cuppa either on the patio or in the kitchen if wet or dreary. Just before Christmas, Katie and John went on one of their trips and next day called me round to share their experience which involved the new CD which they had bought. I enjoy listening to music so this was no chore for me and Katie was looking very sexy in a short dress which she was going to wear the next night at her office party. I noticed just how short it was and got a glimpse of her thong. John had noticed my glance and winked at me as Katie danced solo to one of her favourite songs. After a couple of hours I called it a day, Katie was slumped on a corner of the sofa. she is just 25 and John 29, married three years and full of life. As I am almost fifty, I feel more like an uncle to them but as I live alone, I am always happy to share a few minutes or more with them when they ask. It was 23rd December when I got the shock of my life, John sent me a text saying he needed to chat to me about something and was I free if he called round as he finished work. I sent a 'Yes I am in' note back and waited wondering what he wanted. when he arrived we shook hands as always and he came in. We talked football and he seemed edgy and nervous as if skirting round what he really wanted to say then he turned to me and said he hoped this would not spoil a friendship but he needed to ask me something which might sound odd. I waited with growing uncertainty wanting to learn what the big secret was. 'It's Kate' he said. 'Ok' says I. 'She wants you to fuck her, I can't think of a better way to say it, we have discussed her needs as she is very highly sexed and she has got a thing about older men and you are her perfect choice' I sat down hard, trying to weigh this up. Katie is a sexy thing, very nicely formed and a smiling face with a lovely nature, a very simple choice for a single guy. 'Am I', I sort of stuttered, as you can imagine, it is not every day a husband comes out with such things, apart from a couple of hugs and kisses, always in front of hubby, I have never had any salacious gropes or exchanged knowing looks, so apart from the glimpse of her thong a few nights earlier I had not been given any encouragement or indication of this situation. John explained that he and Katie had a bucket list which they discussed and having her fucked by an older man was high on her list of desires. He was all for it and wanted to enjoy all sorts of other sexual experiences. I had dallied with this scene but had sort of done all I wanted, so having experience, my cock twitched like it never had for a while, not since a shitty divorce almost ten years ago. It was the divorce that made me wary of getting involved again and had become happy with my own company, (less people to fall out with). However my curiosity was roused and I considered the possibility of enjoying a young woman with a lovely body coming to my place for sex with the full knowledge of her husband. I mentioned how important it was that they trusted each other completely and that I would cause no trouble to them after, or if indeed they got cold feet (which I half expected). John looked very relieved and thanked me, shaking my hand and saying he would be in touch very soon. He left and I sat down to absorb the last ten minutes. An hour later my phone rang, it was Katie. She asked if it was allright if she called round a bit later. I said I was doing nothing and would enjoy her company and asked innocently if John was coming too. 'No' and a small giggle. I understood and said I would leave the door unlocked and just come in when she was ready. I ran a shower and changed then waited for my guest. Almost an hour had gone by and I was doubting she would come, but then the door opened and I heard Katie's voice. 'Phil? Are you there?' 'Lounge' I sort of croaked, trying to sound relaxed but failing. Katie entered the room in her short dress, black, a scooped neckline showing the small breasts and the wonder of her hold ups, wish they were stockings and suspenders, but still far better than tights. Katie has blonde hair but is no bimbo, she is a pretty 5' 5'' tall size 10 with a beautiful tight little bum and shapely legs. Her slightly higher pose being shown off by four inch heels. She tottered over to me and smiled, looking down to the floor rather than directly at me. I had dimmed the lights and set what I thought was a romantic scene with the TV off and a bit of music, two glasses ready for the wine which was ready chilled. We sat and drank and talked a bit awkwardly at first then Katie said 'Will you take some pictures on my phone please so I can send them to John' I agreed seeing the sense of her keeping the pictures to her own mobile rather than risking a third party getting hold of them. We sat side by side and eventually kissed gently but building up to full on fondling and kissing of her neck and the exposed part of her breasts, she smelt divine and was encouraging my cock to stiffen as she stroked me over my jeans. We sided the glasses and I undid my jeans for her, she felt inside my pants and drew my thickening cock into view. 'Bigger than John's' she said, drawing the foreskin down and exposing the red end with a lovely sigh. I was in heaven as I watched her go down on me. She licked me and then gave me her phone. I took the hint and John got a picture of his wife being a very naughty girl with her older neighbour, and the older neighbour was very happy about it. She sucked and licked like I had not had for too long, making a note to not wait as long again. I felt my excitement getting me going too quickly and said we needed to stop or it would be over before it had begun. Katie laughed to see how turned on I was and I said maybe it was time to get her clothes off if she had no objection. She stood up and turned her back to me, offering the gold coloured zip for my attention. As I drew it down I saw how wonderfully strong her back looked, a perfect flawless skin, smooth and soft, the black bra strap cutting across that superb body. I helped the garment fall from her body and took her bra off too. Now in her tiny black thong, her bum swallowing the string at the back above the lacy topped hold ups. She looked so fuckable standing in my lounge, just her thong separating her from showing her whole gorgeous nude body. I hooked my fingers in at the sides and drew them down, pulling her thong to her ankles where she kindly finally took them off. My lovely naked neighbour told me to get stripped and sat taking pictures of me getting naked, then handed me the phone while she posed and then sent the pictures next door. John's reply was instant 'Wow you look gorgeous, has he fucked you yet?'. We went upstairs at her request and took more pictures, she of me licking her fabulous shaved cunt and several of her slipping my cock into her pussy lips and then resetting a new pose and repeating. I was dipping my cock in and out of her as she recorded and then i got to take some and she sent some dirty texts to John saying how wet she was and that she wanted me to lick her to orgasm. I did my level best and found that the small interruptions helped me maintain a hard on without getting too excited like earlier, in fact it was like the old days, no strings attached fucking, lots of fun, a new body and bareback too. The fun of the picture taking had run its course and now we were fucking for real, my cock sliding in and most of the way out, a gentle hold and different strengths of thrust, moving around, getting her really dirty. She eventually came on my cock and I asked if she ever squirted and she said she had and loved it. I offered to give her a big come and after a few minutes with her talking dirty to me as she played with her clit while my tongue lashed her cunt, she splattered my face. She actually cried loud and shed tears as she orgasmed, shaking violently with her knees gripping my neck as she unloaded. I now told her she was going to have my cum in her and she grabbed me and pulled me in fiercely. I felt used for an instant and then the familiar rising of my cum as she lay there, pulling me in and demanding my spunk deep in her cunt. 'Fuck me fill me, give me that spunk' I was shattered and Katie slept for a while then woke with a huge grin. 'Can we do it again?' I said I would love to and she cuddled into me. She sent John a text saying she would be a while and spent until six next morning playing and taking advantage of me. Of course I hated every minute. She came back for another session on New Year's day and we spent the night together, advancing the portfolio for John and reinstating my love for sex after too long in the wilderness. Looks like a very good friendship and john has said how much sex he and Katie have been enjoying since that first night, good on them, I am not complaining either.
