Here's a story that just popped into my head and screamed to be published. I'll label it as a one-shot, but if get enough reviews and requests, I have an idea to turn it into a full fic.

Summary: "Pain. Suffering. Torture. A simple midnight run to blow off some steam ended up bringing these things on my sister and I." A kidnap-torture fic with Raph and my OC, the TMNT's eleven-year-old sister, Dani.

Raph's POV

Pain. Suffering. Torture. A simple midnight run to blow off some steam ended up bringing these things on my sister and I.

Leo and I had just gotten into one of our major blowouts, which ended with me giving my older brother a black eye just before my little sister intervened. I was so blinded with rage that Dani, as weak as she was, was easily able to pull me out of the lair, saying, "Come on, Raphie. Let's get some air."

When we climbed out of the sewers to the surface, I immediately started running across the rooftops. Dani, surprisingly, was able to keep up with me, despite her being a human and all, silently running a few feet behind me. Some part of me knew she should be home in bed, it was after one a.m., but I was too distracted with anger to even care.

I wasn't pulled out of my rage until I heard a familiar grunt behind me. I swung around, and saw Dani being held at knife-point by a man all dressed in black. I snarled and ran at the moron who dared to threaten my sis, but was grabbed from behind by a man in a similar uniform.

"Hello, turtle, whose the child?" my heart froze as I watched Agent Bishop walk up to me and Dani.

"Let her go, NOW, Bishop" I snarled my eyes blazing at the thought of any harm coming to Dani, my best friend and baby sister.

Bishop grinned, "How about I just take you both, instead?' I felt something on my neck, and the last thing I heard was Dani screaming my name before everything went black.

I woke up with no memory of where I was or what had happened. I felt pain in my chest and neck. Felt that my hands were bound above my head with chains, as were my feet on ground.

I opened my eyes, and almost threw up. Dani, my baby girl, was hanging across from me, hands also chained above her head. She was bleeding from a cut across her head, and her shoulder looked like it had been dislocated, while her legs hung limply above the ground, looking broken. She wore a muzzle on her mouth and nose, and she had too many bruises on her body to count.

"Dani?" I whispered hoarsely, my eyes burning with love and concern. Was she unconscious? For how long? Was she even…?

Thankfully, she coughed and groaned through her muzzle, letting me know she was alive. Her eyelids fluttered open, and when she locked eyes with me, she mumbled something through her muzzle, tears streaming out of her wide eyes.

"You okay, kiddo? You scared me there for a minute." I chuckled sadly. She shook her head, sobs escaping her body. I said, "Shh, honey, I'm here. Imma get you out, okay?"

She shook her head again, a defeated sorrow that should never be allowed in my baby dampening her usually reckless, beautiful blue eyes. I started fighting the chains, determined to get us out of this mess that I knew was my fault.

That's when the door opened, causing Dani's eyes to widen in horror, frantic whimpers escaping through the muzzle. I growled-I would kill the sick who had scared a little girl this much.

It was Agent Bishop. He chuckled, "Well, it's about time, Raphael. Your sister and I were worried you'd never wake up." He turned to Dani, placing a hand on her good shoulder, "Weren't we, my dear?"

"Don't you dare touch her." I said in a dark, husky voice.

Bishop chuckled again, "Hmmm, well, it's time for her new daily routine." His voice was threatening, and Dani shook like a leaf as Bishop unchained her from the wall and held her by the neck.

I really started fighting the chains. "Let go of her, dammit! She's just a little kid, for crying out loud!"

Dani's head hung, a symbol of defeat. I watched in horror as Bishop drug her out of the room, away from me.

A few minutes later, a small screen was lowered through an opening in the ceiling. The screen flickered on, and I saw Dani strapped to a table, Bishop menacingly grinning over her.

He turned to look at the monitor, "Now, I wouldn't want you to miss the fun. After all, you're next."

That's when he took a scalpel, and made a slow incision in Dani's abdomen. She let out a blood-curdling scream of pain.

"NO! " I roared, fighting my chains like a mad dog on a leash. "OH GOD, PLEASE STOOOOP!"

Tears rolled down my cheeks. This was my entire fault, oh God, not my baby, please…

Bishop was cackling… Dani was crying out in agony, she was fully awake for this torture… I was sobbing, saying, "Please, let her go, not Dani, please…"

What have I done? What have I done?

"I'm sorry, Dani…"
