So many sensitive spots

The naughty brat is tied up to a concrete pillar in the abandoned warehouse, her mistress standing before her with cold, sadistic eyes and a wicked needle wheel in her hand, with which she draws circles over the exposed skin of the tightly bound girl. The sharp points dig into her flesh, eliciting moans and laughter as her mistress's fingers dance mercilessly over every sensitive spot, driving the brat to the brink of madness.
