"Chipped ribs" (Saw parody)

Ignore

Alice's eyes widened as she gasped, she shuddered in fear as she held the knife. Noise was drowned out by a loud ringing in her ears... This can't be... She looked down at her chest, slowly pulling down the collar of her black punk band t-shirt. There were stitches where the x-Ray sheet stated the key was.... She took another deep breath, time was ticking. She already almost has about eleven minutes left before she was cut clean in half. Alice's eyes slowly dulled, her face was emotionless. She looked at the knife with a blurred vision before plucking the stitches. One by one, she ripped each stitch with the tip of the sharp knife. Once she finished, the wound gashed back open, squirting blood onto both her face and the floor... She didn't seem phased.. She was emotionless. Not a thought went trough her head as she continued. It was like her mind just shut down and let her body just go to work. She acted like a new person, but she still had a piece of herself left.
The female slowly cut at the muscle layer that protected the ribs. She let out a small grunt as she continued to cut, but inside she was screaming and crying in agony. She only just began.
Slowly, she peeled off each slab of meat as she cut it away, more and more blood gushed.
After about three minutes she hit the rib. Her heart beated rapidly, pressuring a dull shining object against her rib cage... It was the key. She laughed lightly, trying to hide the pain. She dropped the knife then shoved her small fingers into her chest.. There it was, a loud scream erupted from her throat, it was scratchy and bloody. She tried her best to jerk the key out without cutting her heart. More and more blood gushed. She threw her head back in agony, yelling and groaning. "FUUUUCK!!!" She shouted, tearing the key out and chipping a piece of bone off.
