I have My slave’s cock and balls in a trample box! His cock stretched towards his face and bound OH SO tightly with twine! The slightest movement of his pathetic cock causes the fine string to create a great deal of pain by digging into his skin. Unfortunate for him, yet exhilarating for Me. I walk and twist My feet into his cock with My spikey heels in an attempt to flatten it into the box. I press My spikes into his cock and balls to elicit his reaction to the pressure. Hearing his whimpers and watching him squirm brings Me absolute pleasure.
