This happened many years ago when smoking was the norm,my ex wife who was twenty years my junior were friends with a couple who were also married but his wife suddenly left him , and being friends with both of them that did not make,,,, us take sides but I felt really sorry for him , and it hit him hard so we arranged to travel to his place and take out for a drink ,he got back to us and he was up for it saying why not stay the night,we arrived and he said a mate of his called around so the four of us went to his local pub ,we had a good night which cheered him up ,after chatting for ages my wife said she was tired and I said yes I will join you,our friend said I'll show you your room ,he went back down stairs and we stripped off I always slept commando my partner put on a short see through baby doll nightie ,we kissed and played around a bit then she said i want a cigarette,oh no no ashtray ill go down and get one ,not dressed like that surely ,she picked up a cardigan that she wore earlier and said i wont be long as she left me ,i must have nodded off, when I awoken looking at my watch it was an hour when she went, putting jeans on i walked down stairs the light was off and they were all watching a porn film ,i felt like a real perv looking through the crack in the door , they must have just put the film on my wife was sitting in-between them but still had her cardigan on ,i was getting hard watching so what was the film having on them , then my wife opened her legs and started playing with her smooth cunt , oblivious to the guys either side of her ,she leant back with a groan closing her eyes ,the guys both looked at my wife they both ran a hand up her leg on reaching her wet cunt she removed her hand ,still with her eyes closed she put out a hand either side trying to get to their cocks ,which they had released , she suddenly stood up i thought she must have realised things had gone to far so i rushed up stairs quick , but nothing she wasnt coming upstairs I waited for a while then went back down ,as I looking through the door she was kneeling down in front of our friend sucking his cock as the other guy got up lifted her up a bit so he could slide his cock in her cunt ,he didnt last long before filling her with warm spunk, our friend watching decided that he wanted to shag her ,which he did ,i decided to go upstairs then get into bed ,she still didn't come up ,I had a quick wank before drifting back to sleep 💤
