Take a crap on her
From Create Your Own Story
Unfortunately, you had been having diarrhea problems for the last couple of days, and right now you really need to take a shit. You decide to use Julia as your toilet.
You drag Julia to the floor so that she is lying on her back, and you are on top of her. You trap her arms under your knees so that she can't escape, and pinch her nose so she is forced to breathe through her mouth.
Then, you position your ass so it is directly above her face, look into her eyes, and tell her, "Julia, I'm going to poop on you now." At this point, she starts freaking out, but since she is breathing through her mouth, she cannot scream or make any other noise; all she can do is try to squirm out of your grasp. Julia is hyperventilating, scared for what you are about to do to her.
You exhale as you let out first, an explosive fart, silent but deadly, straight onto Julia's face. It's pretty bad for you, but the stench must be horrible for her. She starts gagging as the stench fills the air. Then you let out a large, warm dump directly onto Julia's face. Her entire face is covered in your brown, partially-watery poop, including some of it that went into her open mouth. You continue pinching her nose, so she has no choice but to gulp down your crap. You see more tears roll down her face, as she cries for the disgust she has to live with for the rest of her life.
Suddenly, your half-asleep mother opens the door - wearing only a sleeping gown - and sees you sitting on your sister, her face covered in your shit. Your mother's face turns to shock.
What happens next?
