Her entire body swelled with pleasure and each time her father speared her with the two pricks, it felt as though they got larger. She frantically wriggled her ass around, inflamed with excitement and needing more.
Suddenly, Mike knew he couldn't hold back any longer. He put on a burst of speed with both his own ten-incher and the twelve-inch prick he held in his hand.
"Now you're going to get it," he hissed.
"Yessss, Daddy! Fill me up! Come inside me!"
His balls exploded and he jetted a stream of hot, thick jism up into her spasming asshole. Wad after wad of the gooey cum shot into her ass, and the girl bucked and screamed with joy.
"Aieeeeee!" Lacey yelled as her cunt exploded in still another orgasm. It felt as though her father were coming right up into her tummy and for a moment she would have sworn that she could taste his cum.
At that moment, Lacey realized just how lucky she was to have a father who loved her enough to show her how wonderful sex between two people can be. During their vacation, he had shown her how to get pleasure from her own body, and how to give it to others. She smiled as she vowed to herself to always give as much sexual pleasure to her father as possible. And to her brothers and to her sisters.
