That sexy glint in a man's eye when he's hurting you... you know it, he knows it, and you both know he's not going to stop until he decides you've had enough - until your panties are soaked and you're begging him to with your eyes.
The timbre of his voice when he gives you an order, you hesitate, and he says, "Now."
That split second of time in between when the cane strikes your flesh and the pain hits.
How hard you come when he's been keeping you on the brink for what feels like forever and then finally gives you permission.
The peak of the burn in your clit when he's swiped it with Tiger Balm just before taking you out for dinner.
Intensity. I love it.
