On Saturday afternoon, my wife had gone to meet her friend and I had some time to read the newspaper and enjoy the sunshine in the garden. After 30 minutes I heard a knock at the door, I thought it might be my wife back but when I answered my neighbour, Sarah was standing there. Sarah actually lives five doors up the road with her husband, Alan. We have lived at our current property for over 20 years and Sarah and Alan moved to their house about a year after us. They seemed quite different from us so we haven’t had much to do with them other than a neighbourly hello now and then. Sarah was very ordinary looking; she looked like Olive from ‘On the Buses’ for those of that era. She was about my age early fifties and had put on some weight over the years. She did have very large breasts, which drooped to her waist. Her husband Alan was retired and a lot older than Sarah and must be mid to late 60s, he was always quite dour. My wife Suzy is 46 and quite the opposite of Sarah, Suzy is a bit of a rock chick, slim, pretty, tattoos and piercings. We have been happily married for 20 years and the last few years we have experimented with swinging and allow each other to do what they want but we are always honest with each other. Anyway, Sarah stood at my doorstep in a t-shirt and leggings and asked if I could help with her security camera settings. We had the same security camera, which is why she had come to us for help. I had answered the door bare chested so I said I would put a t-shirt on and be straight over. Sarah showed me to their computer room upstairs, I asked where Alan was and she said he had gone supermarket shopping and would be out for a couple of hours. The security camera settings were easily resolved and Sarah stood in the doorway to her bedroom and I noticed her erect nipples through her t-shirt and couldn’t help stare and she noticed and blushed. I apologised for looking but confirmed they were very nice nipples. I couldn’t believe it when she said, as a reward for fixing the camera settings I could touch them if I wanted. I walked over to Sarah and gently touched her erect nipples. Her breasts were so large and beautiful I asked if I could touch them under her t-shirt. She nodded and my hands went under her t-shirt to fondle her breasts. She started sighing and moved back onto her bed. She lifted off her t-shirt and I started to lick and suck her nipples and my hand went between her legs over her leggings and it felt warm and moist. She was gyrating her hips towards my hand and my hand moved into her leggings and down her panties to find a hairy but very wet slit which I started to finger. I found the slippery knub of her clit with my thumb as my tongue played with her breasts and hard nipples. Sarah was really moaning loudly and moving her hips to push hard against my hand. She then pulled down her leggings and pants and I took off my t-shirt. Her pussy looked delicious and I lowered myself to lick her sweet hole. I licked all around her vagina my tongue flicked her clit. I even gave her arse a lick. She held my head tight to her pussy and I’m sure she climaxed as her body rocked and her pussy moistened even more. It had a strong smell of sex and mixed with the pubic hair and it was intoxicating. I moved up to kiss Sarah, my chest against her large breast felt great and I rubbed against her. She started to go down on me; her tongue was strong as it darted over my nipples. She sucked my cock hard and licked my balls and arse. I pulled away as I knew I was about to come and asked if she wanted my cock in her. Sarah said she did and it was alright to come in her. She got on all fours and I started to fuck her from behind. I didn’t last long, the combination of her lovely pussy and big swinging tits caused me to orgasm quickly. We lay on the bed and both thanked each other. I asked if she would tell Alan and she said probably not. She told me she only had sex once a month with Alan and it was quite boring. She said she masturbated quite a lot. She asked if I would tell Suzy and I said I would and it would be fine. I asked if she wanted me to cuckold Alan as he might like this, she said that really turned her on but she didn’t know how to approach it. I said give it a go he might welcome it. Sarah asked if I could fuck her once more before Alan came home so she started to lick my balls and then turned around so she was in a 69 position over me. My cum seeped out of pussy as I licked it and it really turned me on so my cock stirred and got hard again more quickly than I thought it might. Sarah moved her pussy and sat on my cock and started to gyrate her hips. Her tits swung freely in front of me and I played with them. She bent forward and we kissed as I shot my second load into her lovely pussy. I asked if she could sit on my face and I would lick her. She moved to sit on my face and I lapped at her really wet pussy and found her clit quite easily and it slipped around my tongue. She pushed her clit into my face and was clearly masturbating using my face to rub against; she came and flooded me with more moisture. We thanked each other again, we got dressed and I told her to think about the cuckold stuff. I also said it would be ok to ask me for a fuck every now and then. I left to enjoy some more sunbathing. An hour later Suzy came home and I told her what had happened. She was a little surprised at my choice of partner and that I hadn’t agreed it beforehand with her, but with a grin she asked if I had a wash since I had done the deed and I said no so she pulled down my shorts and started to suck me off. Suzy is so sexy and I love it that she just loves sucking my cock after I have had sex. I came in her mouth, just a few dribbles left. She said I now owed her a freebie and I said ok as long as you get home quickly with a pussy still seeping cum….she agreed. She also agreed that I could see Sarah as much as I wanted but she did say that she wasn’t interested in Alan…fair enough.
