Corpse Girl tackling, gagging, and headbutting a man

She lunged and tackled him. They tumbled down, and her hand slapped over his mouth. He tried to yell, and she pushed her fingers between his teeth. His tongue twitched against her fingertips. He looked at her and screamed, but it was a stuttering, muffled screech around her knuckles. Then his mouth was opening wide, his tongue pulling back, and he almost gagged trying not to touch her cold skin.
Madelyn pulled herself up on top of him and slammed her forehead down against his. It was a clumsy head butt. She knew there was a certain way to do it, but didn’t know what it was. So she just smacked their skulls together again and hoped the blow would connect right.
