In Kathia's grip

Kathia has Nikki trussed up in her dungeon. The girl's arms and legs are lashed tight, but her breasts hang free, waiting, nipples already stiff. Kathia leans in, takes a pink nipple between finger and thumb and twists, hard. Nikki's mouth opens in a silent cry. The mistress watches her prey squirm against the ropes, then crushes both breasts in her palms, working the flesh until pale skin turns red beneath her grip. Every squeeze draws a broken whimper from the girl. She pushes harder, calculating exactly how much pain the bound body can take before it shatters. Nikki's breath shudders. For now, the pain is bearable. A little more and it will not be.
