It was my sister ...she old me that tbe money for supplies was on her dresser. So I headed to her room when I got there her top drawer was open...when I looked in side all I saw was lace panties, dildos and a few videos.....well since my cock was still rock hard I started getting even more turned on thinking about my sis having sex ..I took a pair of red lace thong s out of her drawer. Then stripped down and put them on ..my cock stuck out the top atleast 5 inches. I looked at the videos.
