When we were younger my wife Kim and I had sex almost every night. I loved to get home from work and get my wife naked as soon as possible. I thought everything was good with us but after we were together for a couple years I started noticing that she had changed. The first change was when I would come home Kim would be in her housecoat most days with little or nothing under the housecoat. I also noticed that Kim had trimmed her pussy hair and you could see her lips hanging open most of the time. I ask her about the change and she said she thought I would like it and I did. I loved being able to slide my tongue along her smooth pussy lips. We fucked like teenagers that night and for several days straight.
I came home a little early one day and thought I would surprise Kim and maybe get a little afternoon delight but as I turned down our street I saw a truck parked next to the house. I drove on by slowly and saw that the truck belonged to a friend of ours. I thought that was strange so I went down the street and called home and after several minutes she answered a bit out of breath. I told her I was coming home early and would be there in about ten minutes. I then parked the car so I could see the house and a couple minutes or friend came out of the house and jumped into his truck and took off.
I drove home and when I walked in she met me at the door in her housecoat. I reached to kiss Kim but she turned her head and I wound up kissing her cheek. I grabbed her and pulled her close and started running my hand inside her housecoat and she tried to stop me but I kept sliding my hand under the housecoat realizing that she was naked underneath the housecoat. Kim kept asking me to behave but I kept after her and when I slid my finger into her pussy she was dripping wet. With my finger inside her wet pussy I ask her what she had been doing to be so wet which she said that she had been reading one of our adult books.
I removed my hand and stepped back and ask her are you sure or is there another reason? I could see that Kim looked afraid but she ask what did I mean? I told her that I saw our friends truck at the house and watched him leave just before I came home and did she have something to tell me. She knew she had been caught and lowered her head saying that he had come by and they had wound up fucking on the couch and when I called he left so I wouldn't see him there. I ask if this was the first time or had this been going on for a while.
