As you already know that Narcissa is a cruel mistress, she always tries only most painful punishments on her pathetic male slaves. She got decent set of BDSM sadistic tools that are widely used on all parts of subs including their vulnerable genitals. That bold slave suffers from insane pain when Narcissa squeezes his ball and attaches metal pincers to his shaved manhood. She really manages to keep that weak slave on the edge!
