Happened about a week ago.
Ever since my wife and I have lived together I always got a weird thrill from folding her panties when I did the laundry. I just always loved the feel of the silk ones along with her cotton boy shorts.
I work at nights so when I get home she is just leaving for work. As soon as she leaves I put on a pair of her panties and fondle and smell the ones she wore the day before. They are still wet from her female juices from that night. It doesn't take long to get a hard-on and I start wanking right away. I cum in her panties in no time.
I often just keep her panties on all day which makes it exciting because I have to change at work where I could get caught. I asked my wife what she thought of the idea of me in her panties. After thinking about it she said she would have to see it first hand to comment. I then stood up and let my pants drop. There I was in a pair of grey and pink boy shorts of hers. Without saying anything she walked over to me and grabbed my obviously excited cock and wanked away. It did not take long for me to blow my load in her panties. From now on she wants me in nothing but her panties. She was so turned on by the idea about me in her panties, especially when I was at work.
I'll write more if I get good reviews.
