This is an original story (incident) that happened in my life and this is a very short piece that I am submitting. Hope you like a short story, as this is just an attempt of change from the routine long stories. Also my last story on the same topic was a bit too long.
I am a married guy for 2 years and my wife and myself were very interested in sex and had sex almost daily. We were not interested in children and so made sure my wife did not conceive. Once we decided to have some adventure. We had a newly married couple just opposite our flat. Theirs was an arranged marriage and so their marriage was by force and both of them didn't like either of them and so were literally staying in separate rooms. My wife collected all these details and I took permission to fuck that girl in return for allowing my wife being fucked by that girl's hubby. So my wife started to arouse that girl with lot of sexual interest by telling our own sex games and at one moment she started to ask for the previous nights plays. Once my wife asked her (the opposite girl) about sex with a stranger. She initially was quite furious saying that it was against the culture. Now my wife sowed the seeds saying that it was not a crime at all. She allowed her to think and at the same time moved with her hubby quite closely. This went on and soon I joined them and started to visit their house regularly and was a welcome guest by that girl and my wife a welcome guest by her hubby.
Once I started to caress the girl so much that even if I talked about sex with my wife she did not felt offended so one day I with my wife decided to put the plan into motion and told my wife of to offer herself to opposite house persons hubby and I offer his wife sex with me. When we initially broke this offer the girl in the house was very furious and asked both of us to get out but her hubby wanted to have sex with my wife as the girl did not give any pleasure to him. To this the girl said "I wished to be truthful to you but you seem to be a stray dog now even I don't even mind having sex with the opposite tenant." We resolved the issue and a day were fixed for the action. I arranged for a web cam secretly and had them fixed in my house bedroom (both the rooms, this was not even aware by the other 3 persons) I connected it to my PC and made sure to have the entire action recorded in my PC. I was able to start recording the same by click of a mouse.
