With a final gasp and sigh, the boy rolled away from her and lay still.

Melissa looked curiously down at her body, at the globs of cum on her tits and stomach. She idly scooped them up with her fingers and popped the salty goo into her mouth. She smiled and ate all the cum he had given her, inside and outside.

Then she rolled over and snuggled close to her brother. "We did it, Carter, we actually did it."

"Yeah."

"We went all the way. We fucked!"

He nodded. He couldn't speak. Me was panting, unable to answer.

"Didn't you like it, Carter?"

He smiled up into her, beautiful, innocent face. "Sis, I loved it!"

And so did I, their father thought, from his hiding place. But I'm going to love it even more later tonight, when I do it myself.

Kyle said good night to his son and then moved on down the hall to Melissa's room. She was sitting on the side of the bed waiting for him when he entered. She was wearing a thin, cotton nightshirt.

Kyle could swear, when she looked up at him with those sensual, knowing eyes, that this young person knew exactly what he intended on doing. You little bitch, he thought, yow really are your mother's daughter!

"Are you ready for bed, baby?"

"Yes, Daddy."

Kyle sat beside her and moved his arm around her shoulders. It was all he could do not to pull out the front of her nightshirt and suck on one of those glorious tits. Instead, he bent and kissed the top of her head, moving his hand from her shoulder under armpit so his fingers lay lightly along the outside bulge of her tit.

The nipple under his fingers was solid even through the nightdress. He longed to tear off the flimsy garment and take her tits in his hands while he devoured her lips and felt his hips riding up between her thighs, and his cock ripping at the lips of her pussy.
