"Open it until her tits are out."

"Oh God!" Amanda whispered. "Oh, please, Sammy, don't do it, please!"

"You wait till you get the shit whipped out of you and say that," spat Sammy viciously. Without any more hesitation she pulled Amanda's dress open to the waist and waited.

Amanda tossed on the ropes, her short dress flying up, showing more of her legs. As if in a dream, she heard Jack tell Sammy to undo her bra.

"No!" Amanda screamed. "Don't do it, Sammy, don't do it! I'll never forgive you if you do that, never!"

She tried desperately to heave herself upward, but the ropes around her ankles held her very securely.

Sammy reached out and unclipped her sister's bra. Now Amanda hung there, her magnificent tits thrust out to Jack's lustful gaze.

With a grin, he slid her dress up until her legs were totally revealed.

"Fuck me! As good as your sister's!" he said.

"Oh boy, is this gonna be fun! Don't leave me now, will you?"

Amanda burst into tears as she saw him pick up the thin cane. He came back toward them, flicking it in the air.

"I dunno," he said thoughtfully, running the trembling length slowly across Amanda's tits. "What do you think? This, or one of the cats?"

The surge of horror in Amanda's throat prevented her from breathing, let alone replying to the terrible threat. She stared at the cane. They had used it many times, but it was as if this was the first time she had seen it. It tapered, ending in a thin round line, no more than a quarter of an inch in diameter. No wonder their wimps had screamed so loudly when it cut into their asses or their bound cocks. And no wonder Sammy had screamed so loud.

"Oh well, if it doesn't work we can always try again," Jack said with a laugh. "Now we're gonna see just how much you love your sister. You said you wanted to see my cock, well here it is!"
