Then Jeanette screamed helplessly, far the gag actually covered most of her face, with holes only for her nose and eyes. She heaved a great breath in through her nostrils as the gag tightened, and screamed, but hardly anything came out. The balls rolled in her mouth and it was all she could do not to swallow them.

Then they grabbed her arms and put leather bonds around them. Jeanette wailed in horror as the ropes attached to the bonds were pulled around the legs of the chair by her sister and Stan. All the time, the two of them grinned and joked with each other, while Jeanette struggled and moaned.

They took her legs and pulled them apart. Jeanette suddenly became aware that her little nightie was rising up over her flesh. She wept and screamed, but she was already helpless, and the gag stopped her from making more than a low moan.

More bonds were put around her ankles. She sobbed, breaking into helpless tears, struggling on the chair back, her ass jerking in shame and horror. They tied her ankles to the back legs of the chair, leaving her imprisoned over the back, helpless.

"Wow," Galvin said, standing back and looking at his victim. "That's some body your sister's got."

"I told you," Vince said, watching from his chair. "Do everything easy, take your time. Now persuade her to do a little cocksucking, or whatever you want. It's almost a pity she isn't dressed better, then she could take it off for us. I always enjoy that."

"She can do that next," Galvin said. "To get us horny again."

"There, now you're thinking," Vince said, and leaned back in the chair.

Instantly, Cora was there, kneeling between his legs, opening her shirt farther and sliding her thrusting tits over his legs.

"Do you want me to make you happy while you watch, darling?" she whispered.

"Yes, but don't make me come," Vince said. "You know what happens when you make me come without permission."
