When my slave misbehaves I take her to my dungeon and ravage her big titties. Watching my slave squirm in pain during her tit punishment session brings a smile to my face. And when my slaves pointer sisters turn a dark shade of purple I know it was a worthwhile torment session. I love to tie up her milk shakes at the base and then watch as the trapped blood enorges her whoppers and slowly turns these bumpers first a flushed crimson and then, eventually, a deep purple. The color change is so satisfying to watch!
