Diapered by the little sister

Part 1

My sister and I were home alone. Again. Our parents were away for the summer holidays so it was just us, which sucked.

I was playing on my phone when my sister came barging in. "What do you want Lucy?" I asked annoyed. "Can you help me find my dolls?" I said yes anyway. I just wanted some peace and I knew if I didn't, she'd probably scream the house down. "Great! It's somewhere in my room."

I just nodded and threw my phone on the sofa. I entered her old room and looked around.

Her old crib lay by the wall, long with all her baby stuff. I have no idea why this stuff is here but who cares? I thought to myself, what if she threw it around the room and it ended up near the crib. I walked up to the crib and used a chair to climb inside.

Her crib was really tall and I was very short.

I looked around but couldn't find it anywhere. Just as I was about to get up, I heard a click.

I suddenly felt very weak and I couldn't use my legs.

My sister came into the room and an evil grin was on her face.

She had my phone in her hand and was on some kind of app.

"What have you done?! Why can't I stand up?" I screamed at her.

"Well, I was on your phone and an ad came up about how I could do some things to you. So I thought why not?" She replied.

"W-what things?" I asked.

"How to turn you, into my baby. Now you'll feel how it's like to be powerless and weak. This app will help me control your body muscles and stuff like that. It even has an online delivery button.
