"I won't tell, Doctor Nancy," Billy said, squirming his naked ass on the table. "I promise."

Doctor Nancy began moving her hand up and down his cock, clinging to his balls with the other hand. She was making soft hissing sounds of pleasure. Billy watched the doctor's hand jacking his cock.

"Are you gonna jack me off, Doctor Nancy?" he asked.

The doctor made a giggling sound, looking into his face. It pleased her that he wasn't bashful. She squeezed his cock.

"Would you like that, honey?" she asked. Billy nodded, grinning widely, his young eyes shining. He lifted his ass, shoving his cock into Doctor Nancy's fist. "I sure would!"

"Okay, baby," she purred. "I'll jack you off. I'd love to jack you off. You can come, can't you?"

"Yes," Billy grunted, squirming his ass about.

"Wonderful!" Doctor Nancy cooed, jerking her fist up and down his cock. She kept hold of his balls as she jacked him off, squeezing and tugging gently. The throbbing of his cock in her fist felt good, and her cunt began to swell between her thighs. She pressed against the table, her eyes hot on the head of his cock as she pumped her fist. "I love to watch a boy come. It excites me to see that creamy juice squirting. I'll jack you off, honey. Ohhh, I'll jack your cock off so good!"

What the doctor was saying excited Billy as much as what she was doing. His cock had never felt harder.

Doctor Nancy pounded her fist up and down, twisting it on his prick. She kept hold of his balls. She was breathing loudly, her lips parted, the tip of her tongue protruding.

"So hard," she whispered. "Such a beautiful, hard cock. Oh, it's going to be such fun to see you come, Billy!"

"That's gonna be soon," he grunted, thrusting his hips up and down, meeting her fist. "It's gonna be real soon!"

"Oh, yes, Billy!" Doctor Nancy moaned, pounding hard on his cock. "Come all you want, when you want! Your cock feels so good, so hard, so hot!"
