"Take your robe off, Bill," Jody gasped as their mouths finally moved apart. "I have to see your cock!"

With what sounded like a growl, Bill quickly removed his robe, and his little sister gasped again when she caught her first sight of his hard cock.

"Oooh," she said in a voice which trembled, "it's so big… can I touch it?"

"I-I don't know, Sis," Bill said, his protest weak and unconvincing. "This is wrong."

"I know, but it's not really all that wrong. I mean, all I want to do is touch it. Please?"

Bill hesitated. He wanted nothing more at that moment than to feel the young girl's soft hand stroking his hard-on. She's right, he told himself as he gazed down at her hard-nippled tits and dripping pussy. She's right. She's just asking to touch my cock. It's not like she's going to suck it or anything like that. What harm can there be in just a touch?

"Sure, Sis, touch it!" he grunted.

With a low moan, Jody reached out with a hand that shook, and she let her fingertips lightly trail down the length of the boy's visibly pulsating prick.

"God!" Bill husked, throwing his head back and clenching his teeth tightly together.

He couldn't believe how good it felt. Many, many young girls had touched his prick before – but never had any girl managed to make him feel like this. Somehow, Jody's innocent touch aroused him with an intensity he had never known before.

"Oooh, I can feel it throbbing," Jody moaned as she ran her fingers up and down his long, thick cock, a little harder this time.

"Squeeze it, Jody! Wrap your fingers around my cock and squeeze it!" Bill growled, hardly able to talk now.

Jody's eyes grew big as she studied her brother's cock, and she wondered if her small hand could even fit all the way around it. She nestled the thick cockshaft against the palm of her hand and spread her fingers out as far as possible. But they could not stretch out far enough to completely encircle the huge prick. When she had grasped as much cockmeat as possible, she squeezed hard.
