last week the lady next door went on vacation and asked me to check her house..she is a good looking granny in her 70's..whilst checking her bedroom i got the urge to look for her panty drawer, which i found rather quickly...she had many silk panties and one black panty that had a white discharge in the cunt area....i smelled it and it had no odor, so i assumed she had washed it but the white discharge stain remained...i licked the stain but it had no taste but as i was licking it i started to get a massive hard on which caused me to get naked and put on her panties...what a thrill went through my body as i started to rub my cock through her panties....looking at myself in her mirror only added to the thrill...when i removed them i saw a good splash of precum which i licked off her cunt area...i then got the urge to jerk off by rubbing her panties against my stiff and bulging cock...after a few minutes, i shot a load into her cunt area and licked that off as much as i could...i took her panties home to dry them out and the stain looked a little whiter...i foilded them back up and placed them in the drawer like i founnd them....when she comes back and wears them and i see her i will be wondering if my cream is touchiong her cunt
