I will bust your balls until you beg for mercy

His balls are her playground, a relentless tease that leaves him panting. She torments with precision, her fingers dancing over his sensitive flesh, eluding his desperate grasp. Sweat drips as pleasure and pain blur, his moans echoing through the room. She slows, then quickens her pace, each touch calculated to drive him to the brink. His body tenses, muscles coiling with every touch. She smiles, knowing his submission is near. The room fills with his ragged breaths and her laughter, a symphony of control and surrender. His mind spirals, caught in a web of sensation, begging for release, for mercy.
