"I'd be afraid to let a guy fuck me," Terri had admitted.

"Why?"

"I don't know. It sounds sorta scary."

"Then start off by sucking one off," her friend suggested.

"How do I do that?"

"It's sorta like jacking him off, only you use your mouth."

"That doesn't tell me much," said Terri, snickering. "I don't know anything about jacking off either."

"Why don't you get Bob to teach you?" Joyce had suggested.

Now, riding next to her big brother in the car, Terri suddenly wondered if he might let her mess around with his prick.

That evening, after checking into a motel and having dinner, Terri stopped by her brother's room for a few minutes before going to her own room for the night. When Bob turned on the television set, Terri plopped herself down in a chair with her shapely young legs spread out in front of her. Still thinking about the exciting conversation she'd had with Joyce, she traced her finger absently around her dimpled navel. It was exposed between her short cut-offs and the halter that covered her firm young breasts. Sitting there with a dreamy expression in her eyes, she was a picture of innocent beauty. But her hot pussy was burning with passion.

She was acutely aware of Bob as he sat across the room watching television. Looking at her handsome brother, she could see why Joyce had suggested him to be her teacher. She suddenly wondered if he would let her jack him off. He'd always treated her as his sweet sister, but maybe she could change his mind this evening.

As the burning between her legs increased, Terri walked across the room, and she sat down on the floor in front of him.

"Bob," she asked, after a few moments of silence. "Do you like me?"

"Of course I do," he said, thinking how cute she always looked. "Why do you ask such a dumb question?"
