"No wonder Mama said you were the best fuck of her life!" Sandy whispered in awe.

"She… she told you about that?" Jack turned pale once more.

"Just before she left Daddy and he started drinking," Sandy sighed, still out of her mind over the bulk of her uncle's cock and nuts. "Just before she ran off, she got bombed one night and told me about the time she seduced you. She said that if poor Daddy could have satisfied her like you did that night, she would have never run around on him all these years!"

"Worthless cunt!" Jack cursed his wild eyed, hot blooded sister-in-law. "All she was good for was fucking and boozing!"

Sandy sat up on the chaise lounge and gripped her uncle's exposed prick as if it were a ball bat, using both of her tiny fists to pump his mighty prick. Sandy licked her lips and smiled up at her uncle, just as she had seen the sexy redhead do with Brad, earlier.

"I want you to fuck me, Uncle Jack!" she said slowly, letting each of her lewd words hit him with maximum effect as she jerked his cock.

"Oh, baby, I… I shouldn't!" Jack groaned, trying to be true to the memory of his late brother, Sandy's father.

"But you will! I just know you will!" Sandy bubbled happily, her little pink tongue lashing out near his thick cock-head.

Jack's big nuts contracted as he saw his cute, thoroughly fuckable niece threatening to lick his knobby prick-tip. He sighed and moved closer to her, until her tongue touched his cock and the warm wetness made him draw his breath in sharply.

"Uhhhh! Ohhhhh, that's right, honey, lick it!" he gasped. "Keep licking my cock, suck it with your sweet little lips!"
