"Let's go fuck," Jeff said.
"Wait, I want to see them," Lucy said. "I can't even see his cock. It's in her ass so deep I can't even see it."
"Jesus, I'm going to dump my wad right in your hand," Jeff said.
Lucy stopped pumping. "Don't waste it."
"I can't help it."
She squeezed the tip of his cockhead and the boy struggled to control himself.
"I'm okay for now," he said. "But I can't take too much of this."
"I think dad's going to come soon. Look at his face."
Jack's breathing was labored and his face a grimace of passion.
"I know just how he feels," Jeff whispered in her ear.
"And I know how she feels," Lucy whispered back.
"Come on, let's fuck," Jeff said. He stood behind her and raised her skirt. He rubbed up against her ass and she melted against him.
"Oh, God, look at Dad," she said. "Jesus Christ!" Jack said. "Have I got an enema for you!"
"Give it to me," Judy cried. "Fuck me in the ass and fill me with your jizz!"
Judy rubbed her clit in a frenzy and squirmed her ass back at her husband's stroking cock. In a moment the warmth of his jism filled her bowels and she came too.
Her cried were muffled by the pillow and together they collapsed on the bed.
"That was the best, hon," Jack said. Judy rolled over and kissed his face and chest and neck. "I love you, baby," she said.
"I love you too."
"No more big mouth?" she asked. "You've got one big mouth I love."
"Mmmmmm, honey, I think it's getting hard again."
"Jesus, you're killing me."
They rested awhile after fucking again, and then Judy rose up and went down to the kitchen. When she returned, she wordlessly handed Jack his robe.
"What?" he said sleepily.
"Get up and follow me," she said. Grumbling under his breath, he followed her into the hall. "What's up?"
They moved outside Lucy's door. The door was open a few inches and Judy stood to one side and motioned to him.
"Your children," she said, stifling a giggle. Jack gazed inside the room and froze when he heard his daughter's moans. "Jesus!" he hissed.
"Quiet or they'll hear," Judy said. "I suspected as much. Look at those two young animals."
Together they watched their children. Both youngsters were naked and they were stretched out on the bed with their arms around each other.
"I'll be damned," Jack said.
Judy took his hand and moved into his arms. Somehow her indiscretions didn't seem important any more. Her son was fucking her daughter. The whale world was crazy. She was fascinated by the sight of Lucy's strong young body writhing around with wild fervor. Jeff's hands were all over her, stroking and probing and caressing.
"Jesus, look at that," Jack said, clutching Judy's ass.
Jeff was sucking one of Lucy's tits into his mouth. Judy watched him roll it around his tongue and bite down on her puckered nipple.
"Our kids," Judy whispered.
"It's good for them," Jack said. "They are cute, aren't they?" Judy said. Jeff held one tit in his hand and squeezed the other. Judy saw a trail of his saliva slip down Lucy's boobs.
"Go for it!" Jack said.
"Ssshhh," Judy giggled as they watched Jeff climb on top of Lucy.
Lucy wrapped her legs around her brother's back as he thrust his prick into her cunt. Judy watched the wet shaft of the boy's cock slide in and out of his sister's cunt.
She leaned against Jack and breathed deeply. It seemed right, somehow. Watching their children fuck after the wild session they just had seemed like the perfect ending to a perfect day. It seemed natural and right and damn cute.
"Are you surprised?" Jack said.
She shook her head. "Not really. Are you?"
"No. I'd be surprised if they weren't fooling around."
"He's well-hung, isn't he?" She bit her lip as she gazed at the boy's cock.
Jack shot her a glance. "She's not bad either."
Suddenly Judy knew that Jack had fucked Lucy. And she realized he knew about her affair with Jeff. She wasn't the only one involved in incest. The whole family was fucking around.
"Your cock is rubbing my clit," Lucy hissed, inside the room.
"Does it feel good?" Jeff croaked. "Great."
"Your cunt feels real tight," he said. "Oh, Jeff, you fuck me so good."
"Better than Dad?"
Judy glanced at her husband, but his face was impassive.
"Oh, fuck you!" Lucy giggled.
Judy reached for Jack's cock. She slipped her hand inside his robe and took it in her fist. She shivered when she realized he was hard again. Obviously, watching his daughter get fucked had given him a hard-on.
Jack untied her robe and felt between her legs.
"You're wet," he said.
"You bet," she said. "This is better than watching a fuck film."
"She's a little girl, isn't she?" She squeezed his prick.
"She sure is."
"We've done okay, hon," Jack said. "Let's leave them alone and go back to bed."
Judy nodded. They had done okay. They certainly had. She smiled and held Jack's cock as they turned away.
