(Author Comment: can't believe I'm writing this as my first story on here... but the idea stuck with me so I wanted to get it out.)
Rachel was now very confused and disoriented. First she'd walked in on her brother sporting a boner, and now? Her brother was looming over her.... she couldn't move, couldn't speak, she could barely even see! Everything was so blurry and dark.... and disgusting. She wanted to retch but she lacked the ability to even do that! The smell of shit overwhelmed her... her body felt squishy and... warm... she felt like a blob of some sort. It felt as if her arms and legs were bound and merged into her body... because they had of course, Rachel still hadn't fully realized her fate. Her vision continued to fade into darkness... the smell and the feelings though... they never left, they only got stronger. Vibrations echoed through her body and translated themselves into... speech? It was muffled and hard to make out, but it sounded like Jeff's voice!
"R.. Rachel?.." Jeff said, not sure what to expect. But it slowly was setting in, this device was real... and it had really turned his sister into a literal piece of shit! If Rachel even was aware, it's not like she could respond. Her body was now nothing but a log of human waste. However, just in case she could hear him, he continued... trying to make excuses for himself. "I'm sorry! Y..you surprised me and I just clicked! This machine I have... it..." Just then Rachel could feel the vibrations of the door opening downstairs, could feel the air current of Jeff looking up. Mom was home. "Shit! Er.. no offense..." What had Jeff meant by that?! She wanted scream, 'CHANGE ME BACK' but all she could do was think it as she laid there helplessly. Coincidentally though, Jeff continued, "Mom's home...I don't have time to change you back... let me.. erm.." Rachel felt her brothers feet land across from her as he left the room and moved down the hall to the bathroom. Where was he going? Why was he leaving her?! 'JEFF! CHANGE ME BACK! WHAT DID YOU DO?!'... but a few moments later those footsteps came back... and the feeling of fingers wrapped around her, clad in some sort of rubber, scooping her off the ground. Her body felt so loose, Jeff's fingers would squish into her and she feared she was about to fall apart! Luckily Jeff was able to lift her in one piece, but parts of her seemed to stick on the floor. Parts that she would slowly lose contact with as her body was scooped into something.. a bag? It felt plastic and it surrounded her. She was starting to feel cold as the heat from her body was sinking away from her. Then Jeff said it, what she was slowly piecing together this whole time. "I'm so sorry for turning you into a turd. I'll fix it, I promise, but I have to stash you for now... I need to figure out the machine and how to change you back."
A turd... A TURD?! Rachel was panicking now, not that her new form would show how she was feeling, she just continued to be an inanimate piece of shit... now a piece of shit in a bag that Jeff was tying in a knot to conceal the smell it made. The smell Rachel had to endure as her entire being... the smell that permeated every bit of her existence. She swayed helplessly as Jeff carried her away, trying to figure out where to stash his former sister. 'JEFF CHANGE ME BACK NOW! THIS IS DISGUSTING! YOU PERV!' she tried to scream so many complaints and profanities, but of course she couldn't. All Jeff was dealing with now was a regular, inanimate turd. He walks down the hallway, then back, then.. he was running out of time. He quickly opens his desk drawer, tosses the sister-turned-shit into it, and closes it. Rachel feels the plastic bag wrapped around her, feels a strange cooling feeling... can almost feel the darkness enveloping her... as she continued to panic and attempt to shout. It was all no use, and eventually she realized that herself. Sitting helplessly in her brother's desk drawer, praying he would make good on his promise, praying she wasn't discovered by someone else and potentially flushed away...
