"Daddy, Mom is getting married to her boyfriend, Gary, this weekend." Amy had just come back from her mother's house with the news about Jim's ex-wife, Linda. She was telling her father this as she worked out some math problems for school the next day.

"Are you happy about that, Amy?" Jim asked her. He knew Amy liked him. "And does he like you?" Jim wanted to know.

"I think so, Daddy. He's nice to me. He watches me sometimes."

"'Watches,' you? What do you mean?" Jim thought he knew very well what she meant.

"I think he thinks I'm nice looking. He looks at my legs when I have shorts on."

Jim didn't find that surprising. Amy, he thought, was sexy and getting sexier as she got older.

"He loves Mommy. I heard them talking in bed one night. Mommy told Gary that she was going to try to be better at sex."

Hmm ... Jim, thought, Linda had always been clumsy in the performance of sex. She didn't think it was so important to be good at it before he divorced her for the ultra-sexy Gloria. Linda had taken Jim for granted in that she didn't feel she needed to do anything but make her pussy available to her husband. Apparently she now felt the need to change her attitude.

Despite her inability to match his current wife's facility for giving and receiving pleasure, Jim still wanted to fuck Linda again sometime.

"Really, darling? That's interesting." Jim wondered what Linda would do to improve? She could certainly be more enthusiastic about blow jobs and take the cock deeper down her throat, he said to himself. Little Mandy could take Jim's cock deeper than Linda. Jim thought then that maybe Amy, outstanding in the performance of fellatio, should coach her mother.

"Amy," Jim began, "does your Mom ever talk to you about sex?

"She thinks I'm too young." She paused and then said, "But I overhead Gary tell her that she should talk to me about it because girls my age are having sex all the time. Mommy was surprised to hear that. Daddy, do you have a favorite times table?"

"Hmm ... I guess I like the 9 times tables. How about you?" he asked her.

"I like the 9s too, and the 5 times table. We're starting to learn about irrational numbers this year ... and decimals." Amy then said, "Daddy, would you get mad at me if I sucked Gary's cock?"

"Uh, no honey, of course not," Jim replied. "What made you think about that?"

"Well, he's nice and I think Mommy's not so good at it. I heard her trying to suck him off one night. It didn't work too well. Okay, I'm done with my homework. Will you fuck me and Mandy now?"

"Well, I'm not sure ... were you a good girl today?" Jim was teasing her now.

"Yes, Daddy and you promised!" she whined.

"Okay, baby, get your sister and we'll go to bed right now!"

"Yay!" she cried and ran into the bedroom she shared with her adopted sister shouting, "C'mon Mandy, we're gonna get laid!"

He heard Mandy reply, "Cool! I'm ready."

Both girls ran into their parents' bedroom and jumped on the king size bed. Gloria was in bed reading.

"Do you guys mind if I just sit here and read?" she asked.

Jim took off his clothes.

"No problem, honey," he answered, "I'm just going to fuck both of the girls before they go to sleep."

"Okay, sweetheart. Give me a kiss!"

Jim kissed Gloria. "I love you!"

Mandy and Amy had come in nude. They knelt down in front of their father and started in with a tandem blow job. Back and forth they went, sucking and stroking his boner.

"Okay, you guys: onto the bed and get into position," he commanded them. "We're going to start with side by side doggy style!"

"Awesome!" Amy said. "Cool!" said Mandy.

Jim thought they looked gorgeous with their cute little tushes lifted up into the air. Mandy had a darker anus than Amy, whose butthole was a rosy pink. Their hairless slits were already dripping. They were kissing each other and giggling.

"Okay, who wants to be first?" he asked.

Amy replied, "Give it to Mandy first!"

Mandy almost shyly said, "Thanks, Amy!" and soul kissed her sister.

"Okay," he said, "Mandy is first. Here I come, sweetheart!"

He plunged his cock into Mandy's sweet little girl cunt; she grunted as he hit home. Amy kissed Mandy's cheek and then turned to watch her dad plow her sister's snatch. Mandy's little body jerked with every hard thrust into her pre-adolescent sex. The drilling started to have its effect. Mandy started whimpering as Amy peered between Mandy's butt cheeks to watch her father's cock ream her little sister's pussy.

"Wow! You're really fucking her!" she said as she looked up at him.

Mandy's cunt felt great to Jim. It was snug and smooth and fucking her from behind offered a nice view of her tiny body. She was a dream to bang.

Amy crawled underneath Mandy's belly and reached up to diddle her clit. That sent Mandy off into an intense orgasm.

"Ah! Ah! Ahh-uh-ahh-uh-ahhh ...!"

Jim stayed inside her until she was done. He gently removed my cock as he still had to pleasure his daughter, Amy.

"Oh, wow, Mandy!" said Amy as Mandy collapsed onto the bed.

Jim wiped the perspiration from his brow. He said to his pretty little girl, "Okay, Amy, are you ready?"

Amy smiled at him as she turned and presented her ass and pussy. She dropped her shoulders to the bed so as to offer a clear target for fucking. Jim put a hand on her hip and guided his cock into his barely twelve year old daughter's twat.

"Oh!" she cried as he rammed her hard. He almost lifted his sweet, tiny blonde child off the bed with his thrusts. He was frenzied now, drilling Amy's snatch ruthlessly.

Mandy by now had recovered and watched the action lying on her side with her head propped up on her elbow. She reached out and touched her sister's hair.

"Oh, Daddy! Fuck me! Fuck me! Fuck me! Oh, God! Oh, God!"

The little girl was losing control and edging toward a climax. Jim reached down and rubbed her clit. It was all Amy needed to cum and cum hard!

"Oh! Oh! Ohhhhhh!!!" she moaned. As her sister did, Amy lay down on the bed, inert. Mandy kissed the back of her neck.

"I love you, Amy," Mandy said as she hugged her close. "You're just the best big sister!"

Out of breath, Amy said to her sister, "Could you suck Daddy off? I don't think I can move!" This made them both start laughing.

Mandy positioned herself in front of Jim on the bed.

"Is this okay, Daddy?"

"Yes, Mandy; that's perfect," he said as she took his wet cock in her mouth. She began to suck and stroke it.

"Mmmm ... it tastes like Amy!" The two of them again started giggling. Mandy resumed her oral ministrations. She was a great cocksucker. Jim delighted in watching her bob her head up and down taking his prick down her throat. It felt great, he thought, to get sucked off by an eleven year old girl.

"That's good head, Mandy," her mother said, looking up from her book. Despite her stated desire to be allowed to keep reading her book, Gloria could not resist fingering her clit as she watched the tender but intense rape of their two underage girls. It was still statutory rape despite the accelerated horniness of their two little children, who loved to fuck.

Mandy was bringing Jim off now.

"Mandy, here it comes! Swallow it all, honey!" He pumped his warm semen into the little minx's mouth. Mandy, true to form, never flinched but swallowed it all down and licked the head of the cock until it was clean. She removed the cock from her mouth with a loud pop, which set the girls giggling again.

"Mandy, darling, that was wonderful!" he said to her.

She beamed at him and said, "Thanks, Daddy. I love sucking you off." She kissed the cockhead while she grinned at Amy. The two started giggling again.

"All right, you two," Gloria, who had just finished cumming, said, "Off to bed."

Amy took Mandy's hand as they toddled off to their bedroom.

"And don't forget to brush your teeth!" she called after them.
