Bound tightly, the sub's cock strains against his restraints, aching for the Euro mistress' touch. She teases him, running her fingers lightly up and down his shaft, making him squirm. Finally, she grasps him firmly, her grip like a vice. She jerks him roughly, her pace varying suddenly, keeping him off balance. His cock leaks profusely, his balls tighten, but she refuses to let him cum. She wants him humiliated, desperate. She slaps his cock against his stomach, making him yelp. His body shakes, his cock twitches, but she relents only when she sees tears welling in his eyes, his cock glistening with a mix of his pre-cum and her saliva.
