i think it would be really hot to combine tenderness and pain. For example, being tenderly kissed and touched, then suddenly and unexpectedly kneed in the nuts. I would fall to the ground, then you could tie me up and i would be completely helpless. You would make me worship you as you sqeezed and twisted by balls with your hands, then tightly wrapped a belt around the top. Then you would softly stroke them, and just when i got used to the pleasure, give them a sharp rap or pound them hard with your knuckles. You wouldn't let me cry out in pain, i would have to praise and worship you. Then you would dig a high heel into the balls. i have always fantacized about a woman in heels balancing on my stomach while stepping on my balls, but that might be hard to balance. You could also step on the head of my penis as you ground my balls. Then you could finish with a few quick kicks, then go back to kneading and sqeezing my balls with your hands, then pull out a stick or whip and give them a few hits before finally letting the pain end.
