I was the first up having to open this morning. After washing up and getting dressed I decided to look in on my sister who had come home pretty drunk last night. She had gotten home after mom so I knew this was not a place I wanted to be later when mom confronted her. She had managed to only get half ready for bed and barely into the covers. I adjusted her bra to feel one of her t*** and jacked off until I squirted my c** on her chest. Then I took a phone picture and drove to work.
