I recently had to spend time at our old place of residence to take care of some business. I contacted my mother-in-law, Cathy, and she told me I could stay at her house. I arrived early afternoon and Cathy was still working, so I dropped by her work to get her house keys. We had a short visit and then I headed to her house to relax.
As soon as I got there, I went straight to the clothes hamper. When I got to the hamper it was full of dirty clothes, and started rummaging thru and found at least 6 or 7 pairs of her dirty panties. The excitement inside me was growing, as was my cock, which was almost rock hard already..
I gathered up all the dirty panties and headed for her bedroom. In there I stripped of all my clothes except for the pair of panties I had taken from her months earlier. My cock was now at full attention, tenting out her panties. I laid down on her bed and started sniffing and checking out each pair. My cock was now throbbing, as her sweet pussy smell gets me so excited. With one pair on my nose and another on my cock masturbating, it wasn't long before I exploded my built up load of cum in her panty crotch.
I was drained and must have dozed off, because the next thing I know I opened my eyes and looked up to see Cathy standing next to the bed wanting to know why her dirty panties was on my face and crotch. Busted. What could I say I was caught red handed. I didn't know what to say, but she said that she knew I had been taking her panties for quite some time, but never thought she would actually catch me at it.
She then said ever since she figured it out, that she got excited thinking about me sniffing and playing with her dirty panties, and it got her very wet. She then told me she would rub her panties and pussy and make herself cum thinking about it. She also told me she started fantasizing about rubbing her sticky wet panties on my face while she had them on and would explode with powerful orgasm's. I was shocked to hear this, and also relieved.
