His hands moved about her body eagerly, as if he couldn't make up his mind where or what to feel. She trembled as his cock throbbed in her mouth. He was dripping a lot, and as her mouth filled, she swallowed the juices thirstily. His hand moved feverishly about her ass, her hip, through the hair of her cunt. The way he moaned excited her, letting her know he was enjoying this. She had no doubt no one else had ever sucked his cock. He had never fucked a girl, but she was sure he jacked off quite a bit. Being the first with a young boy always thrilled her.

Billy began to squirm his ass about. He was no longer feeling of her, but gripping her hip.

"It's all right," she said, sucking from his cock and pressing it at her cheek. "If you have to come, do it, Billy. It's okay if you come in my mouth."

She shoved his hand to her ass, closing his fingers into a firm asscheek.

"Squeeze it, Billy. Squeeze my ass like that. When you feel you're going to come, let it go. I don't mind… you can come in my mouth."

Billy was already trying to press his cock back into her tight, wet, ever-so-hot mouth. Doctor Nancy gurgled and opened her lips. She swallowed his hard-on all the way, her lips writhing in pleasure at the base. She lifted his balls and pressed them to her cheek, moaning as her throat worked at the head of his sweet cock.

His hand dug harshly into her ass cheek. Doctor Nancy wiggled her hips, and began to suck up and down his cock in a frenzy. She was starving to have him come off in her mouth, desperate to feel and taste the steamy spurts of his come juice.

Billy couldn't keep his hips still. He began to pump them up and down. He fucked into Doctor Nancy's sucking mouth, making her whimper with ecstasy. His movements were further evidence of his enjoyment, and she knew she had chosen the right boy this time.
