With a roar, I slam back inside her, impaling myself on the knife. It slices through my skin, and it’s a good job I know where to cut so it’s not fatal, but it hurts like a son of a bitch. The pain surges through me, meeting the flames in my stomach and balls. I take it out on her, fucking her harder, faster, the knife slicing in and out of my body as she screams. Blood drips down from the wound onto our joined bodies, making the passage even slicker. I can’t move much, I don’t want to shred my insides even though the knife is small and just going below the skin.
