"I think… I think," Judy whispered in awe. "Oh Ricky! I think we're… fucking!"

Rick was far too busy to reply. He was holding himself up with his hands, watching his cock slowly slip into that wet heat of her cunt. He was as awed as his sister but the feeling was so good he wasn't about to stop now. He was losing control now, and hardly realizing it, he gave a stab into her cunt.

"Ohhhh!" Judy grunted as a sharp pain cut through her. "Oh, Rick! I don't think… I not sure about…" And the pain was gone, gone as quickly as it had evaporated wben he shoved his finger into her. And as before, Judy felt wave after wave of ecstasy taking its place. "Oh, golly, golly!"

Judy felt a fullness in her cunt that was sending shivers up and down her partially naked body. It was a strange feeling, but a feeling that sent her mind reeling with almost overwhelming ecstasy.

"Is it in me?" she asked in a hushed voice. "Ricky, did you stick it in me?"

"I think so," he replied. "Yes, I did!"

"Ooooooo!"

They had been still, but now the sensations were so great they began to move their hips, and Rick had his cock all the way inside his sister's gripping cunt. They writhed and twisted, plunged and bucked. Rick could no longer hold himself up, and had fallen on top of his sister. Judy wrapped her arms about him, spreading her legs as wide as she could in an effort to get more of his hard, throbbing cock into her burning pussy.

Their breathing came in gasps of delighted surprise and ecstasy. Judy held her brother tightly to her chest with her arms, her hips twisting and bouncing. She closed her smooth thighs against his hips, and met his lunges with powerful upward thrusts of her own. There was a tingling deep inside her body that was unlike the one she felt with his finger. It seemed to Judy that her cunt was forever stretched, forever penetrated farther than anything she could think of… and she loved it!
