Clearly Mistress Krush delights in tormenting and her slaves... Clearly slave knows only to well he is to be 110% compliant! You can see the delight on her face as she slowly pushes and pierces her needles through slaves scrotum to create her art, twenty of them to be precise! Equally it appears she enjoys the torment of dragging and twisting the needles as she slowly removes them! All the excitement has caused Mistress to sweat somewhat, hmm, how useful slave tongue can be in such circumstances!
