Eleven year old Jason stood beside the bedroom door, his eight-inch hard-on raging and dribbling precum into his underpants. He listened intently to his parents talking downstairs. He had been waiting for this moment for weeks and it was finally here. Soon he would have a whole week alone with his mother.

"Here's the number of the hotel I'll be staying at," he heard Martin, his father, say. "And you have my cell number."

'C'mon,' thought Jason. 'Hurry up and leave already!'

"Okay," said Jason's beautiful mother Diane.

"I love you," said Martin.

"I love you, too," said Diane as she kissed her husband goodbye. Rage and jealousy flared through Jason's heart.

Jason listened carefully, his cock throbbing at the sound of every step his father took toward the door. At long last, Jason heard the front door click shut. He waited intently as he heard the doors to his father's car open and shut. Finally, its engine revved up and the car was out the driveway. Jason couldn't hold back his smile.

Jason ran down the stairs as quickly as he could with the massive erection in his pants. He was met by his mother, wearing a wicked smile of her own as she closed the living room curtains.

Jason admired his mother's beauty. It had been over a year since she'd introduced her young son to the pleasures of incest after noticing her son's unusually large endowment and high libido. His mother was a beautiful, curvy woman in her thirties with full buttocks and D-cup breasts that didn't have a hint of sag. She had shiny red hair that fell to her shoulders and glasses that were perfectly suited to her job as a teacher.

But in Jason's opinion, the sexiest part of his mother was the devilish smile she was wearing. It was the smile of a woman who cared only for pleasure, who knew that she was doing something immoral and had no cares about it. It was the smile of a woman who cheated on her husband with her own son and loved every second of it, the smile of a woman who celebrated her own sinfulness. Sometimes she would flash that smile to Jason when her husband wasn't looking, a reminder of their special little secret. No matter how she was dressed, that smile would always send Jason running to his room with an erection, aching for relief. It was a look that Diane reserved only for her son.

Diane pulled her son into a deep kiss. "Let that horse-cock of yours out," she hissed. After a year with only her husband's tiny dick, she was not one for wasting time with words. Jason threw off his pants, freeing the eight-inch monster and letting it stand proudly.

Diane hiked up her flimsy nightdress, showing that she wasn't wearing any panties underneath. "Get on the couch," she commanded.

Jason sat on the couch, his cock pointing straight up. Diane straddled her son's lap, facing him. Mother and son groaned together in pleasure as Diane impaled herself on her son's cock.

"OH GOD!" Diane moaned. "Baby, you're so big!"

Jason began thrusting up into his mother's cunt. "Bigger than Dad?" he asked. He knew the answer but he loved hearing it out loud.

"So much bigger than your father! Oh yes!" Diane gasped in pleasure as her son's thrusts sped up.

Jason could feel his pent-up sperm boiling in his balls. It took all his willpower not to cum inside his mother right there. He held back, wanting to cum with his mother. He needed to push her over the edge and he knew exactly how to do it.

"Mommy, I've got so much cum inside me. I want it to flood your womb. I wanna make you PREGNANT!"

As always, the magic P-word did the trick and Jason felt his mother's cunt tighten around his shaft as she climaxed. "YES! Get your Mommy pregnant! Get me pregnant with your INCEST BABIES!!!"

"OH MOMMY!" Jason felt his balls tighten. A massive load of sperm rushed up his shaft and spurted into his mother's body, filling her womb.

The two incestuous lovers came for almost a full minute before coming down from their high. Diane and Jason lay together on the couch, enjoying the afterglow of their sinful lovemaking. Diane lightly caressed Jason's cock while Jason tenderly sucked and kissed his mother's breasts while massaging her round, white ass.

"Mom?" asked Jason. "What if you really do get pregnant? Didn't Dad have a ve...a vi..."

"A vasectomy?"

"Yeah. Won't he know that the baby isn't his?"

Diane giggled like a mischievous schoolgirl, a sound that sent a little electric thrill through her son's crotch.

"Honey, do you know what 'price fixing' is?"

Jason shook his head.

"Well, that's what your father's going to do on his business trip. And it's against the law. He'll have to raise the baby or else I'll go to the FBI."

Jason was amazed. "You thought of everything, Mom."

"So, do you want to?"

"Make a baby inside my own mother? Oh hell yeah."

"With all the cum you shot inside me, I might be pregnant already."

Jason grinned. "And if you're not, we have a whole week to keep trying."
