"More dominant"

Date: 4/21/2017

M. tells me he wants me to be "more dominant" so I get on top of him and fuck his brains out. Somehow, the left side of my back is full of pieces of glass that pierced my skin. I'm bleeding. We then meet a guy even taller than M., he looks like him, turns out he's his older brother. He takes us somewhere in his car.
