Nika's boots click on the polished floor as she approaches her quivering slave. She commands him to lie down, positioning her feet over his vulnerable cock. With a cruel smile, she presses down, her sharp heels digging into his flesh. The slave gasps, his dick twitching as Nika grinds her boots into him, leaving red welts. She shifts, her heel connecting with his balls, drawing a cry of mixed pain and ecstasy.
