Don't know why i kept going??
This morning I thought i was home alone, i heard my parents leave for work so i decided to j*** off as we all do. I had all my p**** mags spread out across my bed and floor all opened on the centerfolds. Seeing i thought i was alone i went to my parents bathroom and gave a big squirt of moms hand lotion onto my c*** and went back to my room to have fun.I left my door open so i could hear if anyone came home, my sister had stayed at her friends last night so i knew she'd be home sometime. I was standing butt naked stroking away looking at the p***** i had laid out across my room, and i hadn't jacked off in 4 days so i was super h**** and new it was going to be a super big load. I heard a few noises but it wasn't the front door so i paid no attention to them and kept wanking. I was going hard and getting ready to blow and i hear a voice saying "what the f*** you doing?" and i turn round and my sister is standing in my doorway staring at me. Instead of flipping out and stopping I just stood there and wanking away as she yelled at me. I was going so hard i just started to shot my load as she was ranting away at me.
