I was a naughty girl. When I was left home alone, i decided to go snooping through my big sister's room searching for her credit card. But in my search I came across some other slutty sexy items. A light pink thong with only a string that settled in between my pussy lips and buttcheeks. It got soaked because i fucked my tight little pussy so hard. Cum on my sisters panties is evidence, huh? Uh oh...
