After about 3 hours of no one coming in to use him he assumed that everyone was eating or out. But then his sister came in naked which he knew meant that his parents had gone out to do something. She had a towel and a bra and panties with her. After she came in she shut the door and put her stuff down. She turned on the the shower and then she waited for it to get hot. As she was reaching for the knob to turn it on she released a really long wet fart. He has heard that sound before because those farts are only when she hasn't pooped in a week and those stay in the toilet for a couple days.
He watched in horror as she turned around to show him her round ass and plopped down on the seat so hard he thought his jaw was going to break. She had a very short pee at the beginning because she started pushing the shit out almost immediately. It slowly creeped out of her ass because it was 4 inches thick. She stopped so she could breathe and went back at it. The poop eventually got long enough to where it touched the water and when it did Jeff wanted to gag but he couldn't because he was a f**ing toilet. But she still had more so she lifted her ass of the toilet and got out the rest of it. But what he found weird was she didn't let it drop onto the side of the toilet. Instead she held it up and used it like a dildo for her butt.she eventually came and she finished her piss that she had started and got off the toilet.
He was only glad because he got to watch his very hot sister shower and all that.
But it didn't last long because she had just gotten out of the shower and started gaging. At first he thought it was her smelling her own shit but then out loud she said "I hate period sickness." He has heard her throw up before and she was in the bathroom for up to an hour throwing up every 2 minutes or so. She got down on her knees and gaged some more until she finally stated spewing puke. About twenty minutes later the bowl was already half full with puke and almost as high as where the shit was sitting. She finally finished after 40 minutes and the toilet bowl was about three quarters of the way full.
