Let me offer a few pointers.
1) Focus on physical details. How about: “Blood speckled her pillows, giving them a kind of delicate, polka-dot-from-hell pattern.”
2) End each chapter with a hook. Example: “She thought the worst was over. And then she saw the tail of the bullwhip peeking between his legs.”
3) Rewrite your ending. Everyone hates it. Consider crafting one that actually brings women pleasure and satisfaction. Oh, wait, righhhhht . . . .
