I caught my slave's neck with my hips. I could cross grab my legs and knock him out in 15-20 seconds. But I wanted to look as long as possible at his red-purple face, protruding veins on his face, forehead and neck. I contracted the muscles in the inner thigh and made the slave suffer. After I finished squeezing his neck, he could not come to himself for a long time, many vessels burst in his eyes, his ears were ringing and he was very depressed. But I was happy;)
