Kathy was getting thirsty.

Robert and Cindy had ignored her for the past hour. She was uncomfortable, too. She was sure the ropes were cutting off her circulation, but her fingers and toes were not tingling yet. She could wiggle them and they felt all right.

"Please," she said in an unusually contrite voice. "May I have some water?"

Cindy brought a glass of ice water and held it so Kathy could drink. When she finished it, Kathy looked at the girl. She was searching for an ally, but she saw no help in the smoldering gaze of Cindy's eyes.

Cindy sat back on the floor, facing her brother. She crossed her legs, and the fringed dress revealed surprisingly luscious thighs. Kathy saw Cindy's thighs were well-tanned with creamy flesh. And for the first time, she noticed the girl's tits. They were small tits, but they protruded against the top of her fringed dress.

She wondered about these two. They had in no way harmed her, and they had not threatened her. She didn't feel as if she were in any physical danger. She still sat there with her shapely tits revealed; her skirt tucked into the rope, her panties exposed. Now and then they would look at her, but only at her naked tits and thighs and panties.

Cindy tossed the front of her brother's loincloth to one side, exposing his cock and balls again. She began to play with them, and Kathy didn't understand how they could do this and carry on a conversation of insignificant things. Already her cunt was steaming as she watched Cindy play with her brother's cock and balls. She didn't like it that her cunt bubbled with desire, but there was nothing she could do about it. Her eyes watched with heat as Cindy stroked and fondled and caressed her brother's cock and balls.
