Her name was Karen. She lived with her husband a few doors away from us and my husband worked in the same company as hers. Karen was tall and very good looking. My hubby used to remark to me about how much he fancied her and in turn, when we were fucking I would talk to him about her. One night, she asked me to babysit which I agreed to do. My hubby said 'Have a look in her laundry basket while your there.' I told him not to be so pervy, but secretly I decided to do just that.
So once her daughter was settled and asleep I went to the bathroom but there was no laundry hamper. So then, I went into her bedroom and there it was. Inside there was a mixture of clothing but nothing out of the ordinary, and certainly nothing sexy just ordinary knickers and bras and things. I picked up the top pair and found them to be still moist. Clearly she had changed out of these before they went out. I held them for a moment wondering what my hubby would do if he had them. (as if I couldn't guess) Then I took a quick smell of them. From time to time I masturbate fantasizing about another woman but I was blown away by how suddenly horny I was. I went to their bed and found 'her' side. In the bottom draw tucked away was a lovely silver vibrator. I lay on the bed and began to masturbate smelling Karen's pussy and fucking myself with her vibrator. The thought that she had pushed it inside herself sent me into a crashing cum. I mopped up and then noticed that Karen's knickers were pretty much the same colour as mine. So, well I swapped. But I tucked mine under her husband's pillow. I really hope he jacks off into my knickers.
I wore Karen's home and my hubby was waiting up for me. He asked me if I found anything interesting so I told him the whole thing. Lifting my skirt as I did so until I told him I was wearing her knickers. He pounced on me and sucked me through Karen's knickers before masturbating me by fingering my pussy and ass at the same time.
Then we did a lot more than that, but I insisted he call me Karen.
A few days later, Karen called around and I confessed what I had done. She wasn't mad, but she did make me promise that I would have to do her hubby. I asked her if she would do mine and she said she has been jilling off over him for months. Well, great things lie ahead I hope.
