Kneeling before his femdom, a man bites his lip, anticipating her cruel touch. She smiles, her gloved hands reaching for his vulnerable balls. She squeezes, watching his face contort with pain and pleasure. He tries to stifle his groans, but she knows his body's betrayal; his cock twitches, hardening against his will. She laughs, "Such a good little pain slut," before increasing her grip, punishing him for his arousal.
