A dominant female takes pleasure in her submissive's pain, guiding his head down to her crotch, forcing him to take her massive cock deep into his throat. She grabs his hair, pulling him closer, making him gag and choke on her length. She then orders him to lick her balls, to take them into his mouth, to suck and bite gently. The submissive complies, his tongue darting out to tease and taste. But the mistress isn't satisfied yet. She wants to see her sub truly suffer. She retrieves a ball busting device, a heavy, weighted ball that she attaches to her sub's cock and balls. She watches, a sadistic grin on her face, as he winces in pain, his cock and balls swelling and turning a deep red. She continues to torment him, enjoying every second of his agony.
