My lucky slave is waiting patiently for me to arrive, a mysterious scoreboard in his view. I've devised a tease and denial game today, but it will come at a cost. He's been aching for release for weeks, and today I will stroke him, 100 times, in exchange for 100 kicks of his balls. For every 10 kicks he takes, he gets 10 strokes of his cock. I kick harder and harder with each set, yet surprisingly this only increases his arousal. He can cum at any time, but it's almost as if his body won't let him, his balls swollen and painful from brutal swift kicks from my thigh high leather boots. Will he cum in time? Or will he be ballbusted and denied?
