I have posted on here previously which have all been 100% genuine events. My wife R and I have 3 children living at home. R is 38 and I am 44. We have had many encounters involving other people over the years. We aren't hardened swingers in the sense. What I mean is we don't search for people online or try find people. We find this often leads to disappointment. We prefer to live with an open mind and to see what genuine opportunities come our way. This has lead to a lot of exciting encounters over the years. 2020 has been an dreadful time for most due to Covid 19. As soon as the lockdown was imminent we got into a bubble with our family and included the inlaws. We decided the inlaws should come stay with us as our house is a large 5 bed property with a big garden. We kept ourselves to ourselves and pretty much hidden away. Was nice to have evening meals and weekends walking as a family. I was working from home due to the nature of my job, however I could get called out at anytime. My wife is a nurse so we were both categorised as key workers. My mother in law S works as a nursing practitioner so was also working. Father in law D is a train driver so was also working long hours throughout. Our children were attending school throughout lockdown, although it was just the days we had to work and had no care. We all took turns in collecting and dropping the kids at their schools around our working hours. We spent most evenings chatting round the table, drinking wine and eating nice meals. A lot more wine than normal which I'm guessing is the same story throughout the country. Anyway, one day I was called out to a breakdown at a power station and I agreed to drop the kids at school on my way. R had already gone in to work at the hospital. D had gone into work as he was on duty. S was working but was only working the afternoon. To accommodate the Covid situation her surgery had changed hours and staff rotas. I dropped the kids off at school and as I'm driving to work I received a call to say I was no longer needed. The onsite engineers had managed to patch the issue and it would be ok until they could schedule a permanent repair. I returned home and I could hear the shower running. I went into my bedroom as i had moved my office into our bedroom to create room for the inlaws. I powered up my laptop and was going through some emails. I then heard the bathroom door open and S walked along the landing. She saw me sat there and shrieked as she thought she was in alone. She sort of jumped back startled and as she did her towel dropped partially revealing her left breast. She quickly covered up and bollocked me for scaring her. She went off to the spare room to get ready whilst I was laughing. A short time later I shouted I was going down to make a brew and asked if she wanted one. She said yes. So off I went. A short time later she appeared downstairs in her white dressing gown. I handed her a coffee and we sat down chatting. After a while her gown opened slightly and to avoid further embarrassment, I pointed it out. She laughed and said well you've seen my tit already. But covered up regardless. We finished our coffees and I went back upstairs. At this point I started to get aroused at the memory of her surpringley pert tit. I heard S come upstairs and go into the spare room. I could hear her bumping around, closet doors etc so I guessed she was getting ready for work. The doorbell went so I ran downstairs. Another parcel addressed to the wife was handed to me. I closed the door and went back upstairs. On the way up I was able to see into the spare room. S was sat on the edge of the bed in a black lace bra, black knickers and was doing her make up in a small mirror. I had a really good look on way past and I very quickly got an erection. I went into my own room and was telling myself to behave as that was my mother in law who is 58. I sat back at my computer to try take my mind off things. She would go off to work in a couple hours. I'd have a wank and all would be good. Suddenly a scream from next door. A very frightened scream that made me rush in to see what the hell was going on. S was stood with her back against the wall and there was a very large spider on the carpet next to the unit. I laughed and said, fuck sake. Thought someone was dying. She was shouting get rid of it, get rid of it. I grabbed a plastic tub off the unit and caught the spider which to be fair was bigger than others I've seen in my house. I joked it must be homeless as we had moved furniture around to accommodate them. I pretended to throw the spider at her and she screamed and laughed but said again to get rid of it. I opened the window and chucked it out. At that point once we stopped laughing she realied she was stood in front of me in nothing but her undies. She went red and went to grab her dressing gown. I caught her arm and said, it's too late now. I've seen all there is to see. She seemed nervous and asked if I liked what I saw. I admitted I did. She was curvy but well proportioned, a very nice body for a women of 58. I had a really good look at her. I went in to kiss her and she initially responded but then stopped and said no, we can't do this. It was probably best so I turned to walk away. As I got half out the room, S walked up quickly behind me and grabbed me from behind. I turned and we started kissing. Really passionately. She dropped to her knees and undid my Jeans. My cock sprang out and she started sucking me. After a few minutes I pulled her to her feet. We laid in the bed and i was between her legs kissing her. I pulled her tits free over the tops of her bra cups and started sucking her nipples. She was groaning. I moved down her body and pulled her knicker gusset to the side. She had some pubic hair but it was trimmed and very neat. I buried my tongue up her and licked, sucked and fingered her for ages. She built up a rhythm grinding against me and came really hard. She was soaking wet. I knelt up and pulled her knickers off. I wasted no time and pushed my entire length up her. She moaned and I saw her eyes roll. I fucked her had and fast for around 10 mins, we both came really intensely and I pumped my cum into her. We laid there panting and laughed. We kissed slowly and my softening cock slipped out of her. I said I needed a drink and got up to go downstairs. I asked S if she wanted anything. She wanted some fresh orange juice. I turned and looked as I was leaving the room wearing just my boxers. She smiled at me. I went and got us a drink and when I came back up I was expecting her to be getting dressed. She wasn't. She was laid in bed, covered from the waist down but had put her tits back in her bra. I handed her the drink and was about to leave when she took my hand. She said don't be embarrassed. Sit down and let me talk to you. I sat on the bed and listened. She told me her husband had gone off sex years ago. They hadn't been intimate for well over a year. She admitted what we had done is wrong, but also pointed out nobody got hurt if we said nothing. She wanted sex and I provided her with that. Nothing more. I smiled and kissed her check ready to leave. However she had different ideas. She pulled me for a kiss which again got passionate. I ended up laying down kissing her. Fingering her wet sticky cum filled fanny. She pushed me on my back and sat over me. She looked me in the eye and smiled as she lowered herself onto my cock. She rode me had and fast. I released her bra and we were both now naked. I sucked and bit her tits whilst she rode me. After a while we changed positions and I fucked her from behind before pumping my second lot of cum in her. After we both came we decided we needed to get sorted as she had to leave for work. Soon enough S went off to work and I showered and got on with my work. Over the next 6 weeks or so. I fucked S loads of times. She admitted she felt sexually charged and liked been wanted. She even started surprising me on occasion by wearing new thong undies and holdups. We fucked at least 4 maybe 5 times a week. Every chance we had really. Unfortunately the school holidays arrived and S and D decided to go back to their own home. On the day they were going home, I agreed to go with S to the supermarket as they had nothing at all in the fridge at their own house. The shop would be quite big and would probably contain some heavy items. D was working and R was at home with the kids. We set of in her car to the supermarket. S drove us to a local nature reserve. Literally 10 mins away. There were a few cars parked up but it was quiet. I asked why we were there and she said she just wanted one last opportunity to say thank you for accommodating them and for the fun times we had shared. I smiled and said well you could have said that whilst pushing a trolley. She laughed and said yes, but I couldn't do this. At that point she opened my fly, took my cock out and started sucking me. She then straddled me. Hitched up her skirt and pulled her knickers to the side. She sank down onto my cock and fucked me in the car. She rode me fast and frantic, we both came very quickly. She climbed off. Sorted her knickers and we went off to do the shopping. We were soon stood in the checkout. Wearing masks. She leant towards me and told me she could feel my cum running down her leg. We both burst out laughing. Checkout women had no idea what was said. S and D then returned home. I'm sad it's over but now the kids are back at school, you never know. Might have to pop round to hers for coffee on the days she's on lates. Will post any updates.
