Flashing brother-in-law
My sister and her husband ran into hard times a few years ago and had to move in with us. Us being my husband and me and two small children. My sister is the kind of girl who Was very comfortable walking around in her underwear in front of my husband. so with encouragement from my husband I started walking in front of her and her husband in my panties and bra My sister finally got a job which left her husband home alone with me. Well needless to say again with encouragement from husband it soon went to just panties and no bra. One day I took a shower and couldn't open the telcum powder so I opened the door in the all together and asked him to open it. After that I would wrap a towel around me after my shower and he would follow me into the room and watch me brush my hair without the towel on. He never ever tried anything thank god and until this day I don't think my sister even knew what was going on.
Very hot and daring on your part. I can imagine you got quite a thrill flashing him and your husband enjoyed hearing about it.
