"This is great," she cried, frantically rubbing her cunt against his fingers. "Why didn't we ever do this before?"

The little redhead didn't hear his response. Suddenly she was filled with the most incredible pleasure. It took her by surprise and caused her to black out momentarily.

Her orgasm lasted a long time. After tensing up, her pussy exploded. The wild sensations traveled from her cunt down to her toes and up to the top of her head.

She had had orgasms when she masturbated, but nothing like this. When it was over she was left shaken and more excited than ever. When Mark pulled his hand back, she forced him to keep fingering her.

"Don't stop," she said. "Do it again."

She glued her lips to his in one last kiss as she bucked her ass and came again. This orgasm was more mild and when the tremors disappeared she fell back against the pillows.

"Wow, that was the greatest!" she said.

Mark's cock was so stiff he thought it might explode. "Now it's my turn."

"Now I get to jerk you off, you mean," she giggled. Hefting her tits, she fell over on top of the boy. "Will you suck my tits some time?"

"Sure," he grinned. "Sure, I'll do whatever you want."

The two youngsters lay on their sides facing each other. Betsy didn't hesitate, but quickly wrapped her fingers around her cousin's cock. She was surprised to find her cunt twitching again. She gazed down at his prick, thrilled to the core by the feel of its hardness.

"You made me come so good, I want to make you come too," she whispered.

"Yeah, you can do that," he said.

"Am I doing it okay?"

"You can do it a little faster."

His cock twitched and jerked in her hand. She pumped it vigorously and felt his balls jump around in their sack. She used her free hand to cup his balls. He plastered his lips around one of her tits and sucked hard.
