Erica screamed and sobbed as she struggled. She was utterly helpless, her arms and legs stretched to the limit, her ass sticking up in the air on the chair back.

"Not bad," Rhoda said, coming back from the closet.

Both the girls gave sobs as they saw her. In place of her black shoes, she now wore black boots to just below her knees. And that wasn't the worst of it. She paraded before Erica, and showed her the thin cane she carried in her hand. It was wood, about four feet long.

"You two should take a little more care about these things," Rhoda said, examining the bonds. "Care makes the difference between a real good stroke and one they can avoid. Watch."

She pushed Erica, and Erica lurched on the chair back, her ass twisting away from Rhoda.

"Tighten them!"

The boys jumped forward.

"No, please, stop this!" Erica cried as her hands and ankles were grasped and the bonds tightened.

"Now, come on," Rhoda said to Willy as he fumbled with the bonds on Erica's ankles. "Get those pads right. Do you want to mess up her stockings?"

Erica burst into tears and sobbed her heart out.

"Let's try again," Rhoda said, and pushed the bound Erica. This time the weeping girl hardly moved at all, and her ass stayed right where it was. "That's important. You wait till you see the way she jerks from a cane across the ass."

"Yeahhh!" Willy gasped as he and Shaun stood back a little, their eyes on the bound girl and their cocks thrusting against the fronts of their pants.

"Now, watch this and learn. Oh, by the way, girls," Rhoda said, and held up a small key. "This is to the door. It wouldn't hold a tank out, but it'll hold you in. So don't bother trying to escape. It'll be very painful as well as futile."

Amy choked as she struggled in the chair, staring at her helpless cousin bound over the soft chair back. And Louis' eyes were on her too, swinging to devour Erica's wonderful curves and then back to Amy again.
