Yesterday was clothes washing day and it is my sister's job to wash clothes. Yesterday morning, I took my usual crap. I didn't wipe my ass with toilet paper. I stood up and pulled mu tighty whities up. I made a wedgie and place my 4 fingers between my ass cheeks and wiped my ass with my wedgie. I took them off and turned them inside out and placed my underpants on top of the hamper so my underpants would be the first thing she would see. Nothing like my sister seeing a pair of my underpants with fresh shit stains on them. I left the house before she washed the clothes so I don't know how she reacted. When I got home, she gave me hell. She told me she didn't wash my shitty underwear. She called me a pig.
