Should I Pop Them?

Mistress A'IE loves ball trampling. She stands on her slave's balls with full body weight. She grinds his cock and balls, twisting her spiky heel deep. Mistress is enjoying herself immensely. The slave beings to moan, pleading that he can't take any more. Mistress just laughs. He doesn't have any choice in the matter. Maybe she'll just pop his balls and spill testicle all over the slave!
