Paul pushed on. "Why would be scared?"

Lisa pouted and shrugged her shoulders. "Cause it's scary, ya know?"

Paul nodded. "I know. I was scared at first, too!"

Her eyes met his again. "Were you really?"

"Sure. Don't worry about it. Do you have any boyfriends?"

Lisa nodded. "One. His name is Roger. We go to school together. Sometimes he carries my books and I let him hold my hand."

"He holds your hand? Is that all?"

"Uh-huh. Once I let him kiss me."

"On the lips?"

"Yeah."

"Did he put his tongue inside your mouth?"

Lisa giggled. "No! That sounds… dirty!" She was still giggling.

"Didn't you ever like to do dirty things?" Paul asked.

Her face grew pouting and secretive. "I think about dirty things sometimes," she admitted.

"Like what?" Paul persisted.

Lisa squirmed with the exciting agony of her secret. Her little ass wiggled on the bed, her panties stretched still further, and for a brief second Paul thought he got a glimpse of folded pink ‘flesh nestled in shadowy blond curls.

"Tell me!" he bogged her.

"Well… once a couple of years ago I was at my friend Sheryl's house, ya know? And she has a little brother. He was about six or seven then, ya know?"

"Yeah? And what happened?"

Lisa giggled and squirmed, her pretty little face flushing with a mixture of excitement and embarrassment.

"Sheryl talked him into takin' his pants off!" she blurted, laughing and blushing. "We looked at his peter!" she added.

"Wow!" Paul said. "That must really have been exciting!" His head was swirling and his belly tingling.

What the fuck do I think I'm doing? Paul asked himself this little girl is only twelve years old, she's never even been properly kissed, and you're sitting with her, encouraging her to talk dirty, and getting a hard-on for her!

It was true! Talking to Lisa about sex, and watching her beautiful little body had made Paul so excited he could feel his cock stirring inside his pants. He tried to rearrange his legs so it wouldn't show.
