She pulled her smock apart, exposing her tits.

Billy gasped.

Doctor Nancy's tits were round and firm, her nipples a light-brown color, strained in hardness. The tit flesh was a creamy color, looking so smooth.

"Oh, that's great!" Billy gasped, his cock starting to stir as he gazed at Doctor Nancy's tits. "They're nice, Doctor Nancy."

She stepped closer. "You can touch them if you want."

Billy showed nervousness for the first time, but it was the excitement of it. He pressed his hands to Doctor Nancy's tits, feeling and stroking them. He pulled at her nipples, twisting them, making Doctor Nancy gurgle.

"Suck them, Billy," she urged.

Billy eagerly lifted his head, taking a nipple into his mouth. Doctor Nancy held the back of his head, pulling his young face tightly. Billy sucked hard on her nipple, his tongue licking. Doctor Nancy purred softly, twisting her shoulders to shove her other nipple into his mouth.

"Mmmmm, you suck my tits good, honey," she whimpered, running her hand to his cock again. She cupped his cock and balls, pressing and feeling. "You're getting hard again."

She pulled her tit from his mouth, standing back again. His cock stood up in stiffness once more.

"How would you like to see me, Billy?" she asked. "I'm naked under this smock. I'm not wearing anything at all. No bra, no panties… just me only. I'm absolutely naked under it."

"Can I?" Billy asked eagerly. "Can I see you naked, Doctor Nancy?"

She grinned lewdly at him as her fingers opened the rest of the buttons. She pulled her smock open, holding it wide.

Billy's eyes became enormous as he looked at her.

Doctor Nancy was in her early thirties, tall and slender. Her tits strained out, nipples tilted upward. Her waist was small, hips rounded. But it was the thick triangle of cunt hair that held Billy's attention.
