When my slave misbehaves I take her to my toyroom & ravage her large tits. Watching my slave squirm in pain during her melon torment session brings smile to my face. & when my slaves its turn dark shade of purple I know it was good punishment session. I love to tie up her tits at base & then look as trapped veins enorges her boobs & slowly turns those tits first flushed crimson & then, eventually, deep purple. The color change is so satisfying to watch!
