Gagged and tied

When Adriana caught the look in Kathia's eyes she froze. The thought of escape vanished. Kathia knew exactly how every strap should sit on skin. Adriana opened her mouth for a final protest, then the ball was wedged between her teeth and pulled tight. Rope followed, coil after coil across breasts and belly, behind knees, around wrists. Ankles pinned. Every joint fixed. Kathia stepped back and let the silence settle. Slow now. Every slap of the crop dragged out so the sting would sink deep and stay. After the first bite, Adriana trembled. She could already feel tomorrow's ache.
