I am a happy married man over the last few years I have taken a real intrest to my mother in law a mature women age 62. One year I had a big purple theme party where my mother in law arrived dresses in a very tight purple velvet dress. It hugged her solid body & exposed her upper breasts. During that night she danced with me up close, I told her how great she looked, she replied with a big smile quoting "Im even wearing a purple g-string". I was stunded as she is a little conservative. Though out the night I noticed the outline of her thong againsts her dress it was hot and couldnt get her out of my mind. The next day I had to go to her place & drop off some borrowed equipment. After some time there I used her bathroom & noticed her purple panty laying on the floor, I became so extremely aroused knowing that was the very underware wrapped around her pussy last nite.. I had to pick it up I was shaking with excitment as I did I noticed her soiled stains their was quite a build up of creamy dry vaginal discharge marking. I was so hard at this stage I couldnt resist the erge I sniffed, licked & sucked her underware until I had cleaned every speck with my tongue & face. I pulled my pants down in a frenzy I had a drip of pre cum from the excitment, the pussy smell & taste of her panties was amazing I came so hard with the biggest load ever in only minutes. I now fantasize about my mother in law every day, I know I would never get the chance to make love to her but the thought of her makes me come so easy and I will never forget the best orgasam I had all from her pantys.
