You took some time to actually clean Maddie before redressing her in a fresh diaper and a shirt you found in the back of her closet that had a unicorn on it.
“How about this shirt?” You ask, holding it up to her and laughing.
“NO WAY! I’m not going to wear some girly rainbow shirt.”
She struggled against you as you pulled the shirt down over her head. The gap between the hem of the shirt and her diaper shows how long it’s been since she got this shirt.
~The diaper you’re wearing will not ever break, only stretch, and cannot be taken off by anyone but me. The waist and leg holes will remain tight, not allowing pee or poop to leave or anything to get in. The command to only let me clean you is still in effect, however you can poop and pee on your own.~ you command, finishing up by tying her hair into two ponytails. You leave to much protest from Maddie, with a “See you tomorrow”, you’re gone.
8 years later
The past 8 years had been fun for you, using the Sapphire to get yourself a good job, beautiful women, and anything else a man in his mid twenties could want. But recently you have been getting the desire to return to your hometown where it all began.
Letting yourself in to the first house that you first tested the sapphire, you were struck by the smell of human waste fruitlessly being masked by perfumes and air fresheners. Maddie’s mother welcomed you with a smile, the ‘content with my presence’ command still going strong.
“Good to see you! It’s been so long, Maddie’s in her room.”
As You head upstairs, to the source of the stench, you hear a bit of conversation.
“I’m gonna squeeze my way downstairs and order us some pizza, that alright?”
As you turn the corner you see her. You hardly recognized her given the layers of dirt and stains, not to mention how much she grew, but it was definitely Madison.
She was tall, with decently sized breasts that were mostly left uncovered by the faded, stained unicorn shirt stretched over her mature body. Her hair was down to her knees, with the last inches still in ponytails. Her face and body were matted in dirt, sweat, and stains. But it was the diaper that made you stop. It was so stretched to the point that it took up the entire hall behind her. You couldn’t tell how far back it went but what you did know was that this is 8 years of poop and pee contained in a single diaper.
