"You can have some, too," Cindy laughed. "Don't it feel good to have Robert's came juice on your legs and tits, Kathy?"

"Untie me, please!" Kathy whimpered. "Please, Cindy, untie me. I won't tell your parents. I promise."

Cindy looked at her brother. "You think we can trust her, Robert?"

Robert looked at the clock on the fireplace mantel. "We gotta let her go, Cindy. It's almost time for our parents to come home."

Cindy untied the ropes, and the first thing Kathy did was to shove her skirt down. Then she replaced her bra and buttoned her blouse. She walked into the kitchen and drank a huge glass of water. When she returned to the living room, she saw that Robert and Cindy had dressed. She sat on an over-stuffed chair, trying not to look at them. She was in turmoil of indecision.

She knew she should say something to their parents about what had happened, but some how she couldn't. She could not deny she had enjoyed herself. She decided she would remain quiet, but she would never again baby sit Robert and Cindy. She didn't trust them now. There was no telling what they would try next.

There was an undeniable attraction about the two, Kathy knew. There was something exciting about them, something erotic.

When their parents arrived, Robert and Cindy were like two well-behaved children. They said goodbye to Kathy politely when she left the house.

At her home, Kathy got out of the car and thanked their father for bringing her home. "They're very nice children, Mr. Haynes," Kathy said.

"Perhaps you'd like to stay with them again," Mr. Haynes replied. "Sitters are difficult to get, and Robert and Cindy seem to like you."

Kathy hesitated, and then found herself answering, "I'd like to, very much."
