Cassie walked into her room, a spring in her step as she made her way towards the bathroom. She was wearing her favorite band t-shirt and a pair of shorts, both of which were already starting to feel tight against her body. She couldn't contain her excitement; she had been feeling an incredible urge to take a massive shit for hours now. Her bowels were about to explode.
She locked the door behind her and quickly made her way to the toilet, sitting down heavily on the cold porcelain seat. She couldn't help but let out a long, airy fart as she felt the pressure release slightly from her full backside. It felt so good but also incredibly naughty at the same time. She had been experimenting with this newfound fetish recently, and it was quickly becoming one of her favorite things to do.
Cassie didn't even bother trying to undress any further. She could already feel her pussy dripping with excitement from the thought of what was about to happen. She leaned forward and placed both hands on the cool surface of the toilet, gently pushing down against the thick bulk that was straining against her digestive system.
It was exquisite torture, but she couldn't wait any longer. Cassie pushed with all her might, feeling the hot liquid seep out of her pussy as she did so. The thick, heavy shit seemed to stretch her insides in all sorts of wonderful ways, and she couldn't help but moan softly as she lost herself in the sensation.
She pushed and pushed, feeling piece after piece of fecal matter escape from her bowels. Two particularly long, thick turds emerged, stretching her sphincter wider than it had ever been before. They were so satisfying that she couldn't help but squirt a little bit of her arousal all over the floor.
Despite the intense release, Cassie knew that there was still more to come. She could feel the soft, squishy evidence of her remaining waste protesting against the emptiness of her bowels. With a final push, she managed to expel the last of it from her body, letting out a long, satisfied groan as she did so.
Finally, she wiped herself clean, taking her time to rub each dirty piece of toilet paper gently against her tender anus, savoring the sweet pain. When she was finally satisfied, she flushed the toilet, watching as the water swirled around the evidence of her recent indulgence. She took a deep breath, feeling both dirty and incredibly aroused at the same time.
