My wife and I have been married for over 25 years and have two grown up children. My wife (Claire) is a good looking woman for her age with a sexy curvy figure that does attract a few glances when we are out. Our sex life is generally good and I’m not aware of any infidelity since we got together. That was all until around a month ago…. I was supposed to go to Germany with my work for a few days and so left as normal on Monday morning - was due to do a day in the office before flying to Frankfurt that evening and fly home on Wednesday night. During the day it became clear that the trip did not need to happen and flights and hotel were cancelled. I left the office at seven and thought I’d surprise Claire and take her out for something to eat. I drove home and got there about 7:40. There was a black VW Golf car on our drive so I parked at the side of our house, suddenly I felt uneasy and confused, I didn’t know the car and my suspicions were aroused. Something felt off. I had my keys so I walked past the VW and entered the house by the side door, I quietly checked the ground floor of the house and there was no signs of life. I took my shoes off and very quietly walked up the stairs… I was shaking with a kind of nervous fear. I stood outside our bedroom door, I could hear faint sounds at first, there were clearly people in there. Then I heard Claire saying something about that being nice, then I heard a man’s voice. I stood there in disbelief for ages, hearing more sounds including what sounded like moaning and sexual pleasure. I didn’t know what to do. I considered bursting in and catching Claire in the act but I didn’t have the guts. Eventually, I slowly walked down the stairs, put my shoes back on and quietly left the house, returning to my car I drove to a quiet spot to sit alone and contemplate what I just discovered. My wife on 20 odd years was having sex with another man in our marital bed when she thought I was away. Given I go away regularly I quickly thought how long has this been going on.

Pulling myself together I checked into a local Premier Inn, text my wife saying I’d arrived in Germany, she politely text back almost immediately. I masturbated furiously that night thinking about Claire fucking another guy. The dirty fucking slut, I had no idea what she was capable of and how long she’d been doing this kind of thing. I went to work on Tuesday and Wednesday (staying in the Premier Inn on Tuesday night) before arriving home late on Wednesday as if I’d been to Germany. I was met with a hug and a kiss and a generally loving wife. I quickly noticed the bedsheets had been changed. When we went to bed I felt turned on and initiated intimacy, my wife complied and we had a lengthy session where I was incredibly turned on, I saw Claire for the slut she clearly is and fucked her like she didn’t matter. Claire did remark on how rough and turned on I was. Our sex life has been great over recent weeks but this is tearing me apart. I have made out I am going away after Easter - although I’m not but a plan to watch the house to see who comes and goes. I know this story doesn’t have the graphics of many of the accounts on here but it is an accurate reflection of a situation in my life that I’m uncomfortable with. I’d be grateful to hear from anyone who has been through anything similar. On the one hand I’m upset and horrified by what has unfolded but on the other I’m masturbating over the thought of another guy fucking my wife in our bed.
