Alex clarifies the boundaries.

You walk go into your room, slamming the door behind you, but the door stops on Kevin's foot.

"Hey cumslut, where are you going?" He asks, smiling wide.

"To my room, you're lucky I'm not kicking your ass right now!" You shout, angrily pulling open your dresser drawer and pulling out the towel you usually use to clean up after masturbating.

"You, kick my ass?" Kevin laughs. "The way I see it, your body is weak and you won't change back for a couple more hours. I own you."

"Really." You say, rubbing the towel between your cum-slicked legs. Your eyes fall on your screwdriver, sitting in your top drawer.

"Really." He says, reaching around your sides again.

Your idea never fully forms, you grab the screwdriver and plunge it into him before you have much time to think.

Kevin falls to the ground, screaming in pain.

You look at the blood soaked screwdriver in your hand, the red drips slowly down the handle.
The stab wasn't aimed, though in your head you had assumed the hip or thigh would get hit. It looks like the shaft through his side into his kidney, it probably hit something important.

"Now you are my bitch." You say. "I own your life, can you convince me to save it?"

Kevin looks at you, clutching his side.
