In a dimly lit dungeon, I'm bound, my balls aching from the tight cage. My femdom mistress looms, her heels clicking on the stone floor. She circles me, her whip flicking against her thigh, a cruel smile playing on her lips. "Balls are my plaything today," she purrs, running a sharp nail over my trapped orbs. She demonstrates her power, making me squirm and beg, before unleashing a flurry of stinging lashes. My balls swell, my cock throbs, yet I know no relief until she allows it.
