CHAPTER 1

Kyle was a tall, muscular 18 year old. It was summer vacation and he was home almost every day with his mother, while his father had to work.

Julie was a 38 year old maternal beauty. She was about six feet, 130 pounds, with long, brown hair, sparkling brown eyes, long, milky-white legs, a remarkably round ass, and even more remarkably big boobs. She exercised daily, almost fanatically, so her body stayed in top shape. Her body was soft, feminine, and curvy, yet somehow surprisingly firm and muscular at the same time.

Kyle was very successful with girls his age, since he was charming, handsome, had a huge penis, and knew how to use it. But he often wondered what it would be like to fuck his mother. She was the hottest mother in the neighborhood, by far. All his friends said so. He longed to prop her feet on his shoulders and feel his large cock saw in and out of her sweet cunt. He wanted so badly to dump his load deep into her womb, where his mother's eggs would surely be waiting.

Julie knew her son (and her only child) carnally desired her. It was obvious by the looks he'd been giving her. A part of her was flattered by her son's admiration, and any woman would admit that the boy was muscular and handsome. But he was her son and she was happily married to her husband of 20 years, Jim. Given time, she was confident her son's fascination for her would pass.

Kyle came down to breakfast in nothing but his boxers, where he found his mother at the stove cooking. He paused to admire her long gorgeous legs and shapely ass. Julie was in just a short, blue silk robe and a dainty pair of high-heeled slippers. She noticed her boy staring at her ass from the doorway.

"Good morning, sleepy-head," she said in her sweet, motherly tone, while still facing away from him.

"Morning, Mom." Kyle answered. He walked up behind his mother and gave her a hug from behind.

Julie turned her head to him and smiled. She could feel his large, erect penis pressed against the crack of her ass. She knew that her son's endowment was much larger than her husband's, thanks to seeing the size of his tenting bulge through whatever he was wearing, and more recently from sometimes brushing up against it. Not for the first time, she figured it was diplomatic to pretend it wasn't there.

"How'd you sleep?" she asked, even as she secretly reveled in the feeling of his hard-on nestling into her ass crack.

"Okay, I guess. Is Dad gone already?" he asked. His muscular arms were just under her huge rack. He could feel the weight of her spongy tits resting on the top of his arms. He also was able to sense that she wasn't wearing a bra, since her bras were thick and heavy to support her hefty, round boobs.

"Yeah, he left a few minutes ago." Julie answered.

Her husband Jim was a financial analyst and wore a three-piece suit to his downtown office, where he worked nine to five every business day. His six-figure salary meant the family was able to live in an upper class house in suburbia and Julie didn't have to work.

She knew why her son had asked about Jim. Kyle's behavior was much different when his father wasn't there. He became much more touchy-feely with her. She didn't mind, and even kind of encouraged him at times. She told herself the horny teen was just going through a stage and he would never try anything "over the line" without her consent.

Kyle squeezed his mother tightly. His shaft was beginning to wedge deeper into the crack of his her ass. He gently and carefully repositioned his hands until they were "accidentally" cupping the undersides her immense globes.

"I love you, Mom," he said, creating an excuse for the intimate hug to keep going.

Julie reached back and stoked the back of Kyle's head lovingly, her long nails combing through his dark brown hair. She twisted her upper torso and looked over her shoulder into his brilliant brown eyes.

"I know you do, Sweetie, and I love you... more than you know," she said. She was secretly thrilling from their unusually intimate contact. It was outrageous the way he was cupping her tits, and it was something she'd almost never allowed him to do before, but the throbbing of his huge erection in her ass crack was even more exciting. That was only rarely allowed too, and never both actions at once.

He was overcome with lust and love for her. He struggled to express his desire for her. "I mean... I... I really love you, Mom... I..."

Julie turned to fully face him, and placed her finger over Kyle's mouth. That forced their naughty ass and breast contact to come to an end. "SSSSHHHHH! I know, Sweetie. You don't have to explain it to me, I know what you're going through," she said warmly.

"You do?" Kyle asked with worry. His incestuous desire for her could hardly have been more obvious (when Jim wasn't around), but it was something that had never been openly acknowledged before.

"Yes, and it's perfectly naturally for boys your age to love their mother's this way." Julie stepped forward and enveloped him in another hug. That allowed her massive breasts to squash against his hunky chest. The feel of her silky blue robe against his bare chest was electric for both of them.

"Tell me what you're feeling?" she asked encouragingly.

"Jealousy, I guess." he muttered sadly.

"Youre jealous of your father, because I'm his?" she asked. Her nipples were stiffening because she secretly found his rampant desire for her flattering and exciting. She was kind of regretting not wearing a bra, or panties for that matter. She was worried he'd be too encouraged when he felt her arousal through her erect nipples. The flirting should only go so far, she figured.

"Yeah." He sighed. "And I guess... I guess I know how much you want a baby and... well..."

There was a short pause. Then Julie took her boy's hand and smiled up into his eyes. Her silk-covered erect nipples continued to press into his bare chest. "So you're jealous that I'm trying to have a baby with your father and not with you?"

"Yeah," he boldly admitted. "I'm sorry, I know it sounds stupid," he said, feeling defeated. "It's just that I love you so very much, and you're so beautiful that it hurts!"

Her heart thumped faster and faster, and she could even feel her pussy starting to throb and moisten a little bit. She felt a wicked desire to kiss his lips, but she knew it could never happen. "It's not stupid, Sweetie. Your feelings are very real. The truth is your father and I have been trying to have a baby for seven long years, and so far... no luck."

"For that long? Is everything okay with you?" Kyle asked. His penis was still throbbing needfully in his boxers, but he was genuinely concerned for them. He was looking forward to having a new sibling too.

"I'm fine, but I'm afraid your father has a very low sperm count. That's what the doctor told us recently. It's possible that he may never be able to get me pregnant again," she admitted in a low tone.

Kyle's eyes lit up. He had what he thought was a brilliant idea. "Well, why don't you let me try, Mom?! I know I could do it, really!" He exclaimed excitedly. His heart thumped wildly and his erection lurched with new life.

Julie giggled. They still stood very close facing each other, her hands resting on her son's shoulders, and her silk-covered huge breasts still pressing into his bare chest, with her stiff nipples poking noticeably into him. "Hold it, mister. You know that you and I can't go there."

Even as she said that, she secretly wished it was somehow possible for them to get intimate. Sometimes, in fact often times, she fantasized about being "taken" by her own son! Lately, she'd been getting a little crazy with allowing him to flirt with her when Jim wasn't home. Plus, she was dressing far too "casually" when they were alone, such as the silky robe and high heeled slipped she had on now... and nothing underneath! But she told herself that some "harmless flirting" was one thing, actual sex was quite another!

"Why not?! Dad wouldn't have to know. You could tell him the baby was his. It would be our secret," Kyle suggested. His erection was throbbing needfully in his boxers.

Julie felt another secret rush of arousal. She thought, I could picture it, getting repeatedly fucked by my extremely handsome, well-hung son, and passing the baby off as Jim's. So wicked! Her pussy was getting wetter just from the idea.

But she felt she had to shut him down before he got too carried away with the impossible idea. She laughed and shook her head. "Kyle, listen to yourself. Do you realize what you're asking me?!"

"It makes sense, doesn't it? You could get pregnant without having to cheat on Dad." His lust was surging so strongly that he boldly slipped his hands down to her ass. That allowed him to pull her in closer until her pussy mound was pressing up against his huge boner!

She quietly gasped and her heart thumped faster as she felt the sheer size of his arousal. However, she pretended not to notice. "But I would be cheating on your father... with you."

"Yeah, technically, but the kid would look like Dad and everything. No harm, no foul, right? Mom, I promise I would never say a thing." Kyle pleaded.

Julie was tempted, sorely tempted. She already knew her son's penis was twice the size of her husband's, and she longed to be truly, royally fucked at least once in her life. Feeling his bulging arousal hotly pressing through her silky robe really drove home how exceptionally endowed he was. However, she remembered how much she loved Jim, despite her years of sexual disappointment with him. It was a fun fantasy to imagine getting fucked by her son, but it could never, ever actually happen.

She told him sadly, "Sweetie, we can't."

"Why? Why can't we, Mom? You want this baby desperately badly," he pointed out. "Wouldn't you go to extreme lengths to make it happen?!"

"Yes, but not at the cost of my marriage! Son, this idea of yours isn't about me having a baby. I know you, you naughty boy. This is about you getting into my panties. I have never once in 20 years of marriage cheated on your father and I don't intend to break that streak with my overly-horny 18 year old son," Julie said firmly.

She felt better for taking a clear stand on the issue, but she still couldn't get herself to pull back from their hug. She continued to secretly thrill at the feel of her immense tits pressing against his bare chest, and his throbbing boner pressing against her lower tummy.

Kyle hung his head for a moment, then looked back at her. "What if I get his permission?" he asked with renewed hope.

Julie let out a surprised giggle. "Your father's permission? Seriously?!"

"Yeah. What if Dad agrees to let me get you pregnant?"

"Good luck with that!" She laughed with even more amusement, because she considered the idea so preposterous.

"No. seriously. What if Dad says it's okay?" he asked with surprising insistence.

"You would actually have the guts to ask your father to get me pregnant?! That's dangerous!" She felt another surge of lust that her son was so hot for her that he would do stupid things.

"What if he agrees to it?" he persisted.

Julie's face went blank for a moment and she stared off into space. God! What if?! That would be heavenly! I'd finally get to fulfill my naughty incestuous fantasy. And with full permission, so no guilt! Well, not much guilt, anyway. And I'd get to be a mommy all over again! I want that so much that I can't stand it!

Her arousal soared even higher. She didn't realize it, but as she wiggled excitedly against her son, her robe started to open up in front.

But what's the point in imagining? There's no way in hell Jim would ever agree. He's rather chop his own arms off, I'm sure!

"What if Dad says it's okay?" Kyle asked again, almost annoying with his persistence.

"First of all, there's no damn way your father is going to let his son, of all people, have a crack at his wife. He might even kick you out of the house or something drastic like that for merely asking!" she said with genuine concern.

"But what if he says 'yes?'" Kyle asked.

"Well, if he says yes, which I know he won't, then... I'd... I'd be willing to sit down with you and discuss it," she said seriously. She felt more jolts of pleasure race up and down her spine just from thinking about what could be, in a perfect world.

"You and me making a baby together? The old-fashioned way?!" Kyle asked almost breathlessly. He had remarkable control over his urge to cum, usually, but he was teetering on the verge of shooting off his cum load just from thinking about that possibility.

"Yes, I'd be willing to discuss the possibility of you and me making a baby together," she said carefully, trying not to sound too encouraging for what she considered a doomed and crazy suggestion.

She finally managed to break the hug with him, if only because she was getting so worked up that she worried he'd notice. But by pulling back, she unthinkingly showed off how her robe had opened up in front, revealing a dramatic amount of cleavage, all the way to her belly button! The robe was so open that he could see parts of her nipples, and in fact it was the stiffness of her nipples that caught the edges of the robe and stopped it from opening still further.

Kyle cheered in triumph. He definitely noticed her partially exposed boobs, but he was so overjoyed that that was just like the icing on his very delicious cake.

Then, overcome by joy, he hugged his mother tightly and then lifted her entire body up off the floor! He actually hefted her up and down some, like he was doing his usual daily weight lifting and she was his bar bells.

That caused her silky blue robe to open up even more in front, until even her erect nipples could be seen! Her huge tits flopped up and down in the open each time he lifted her up and down.

She squealed in both sexual excitement and distress, "Son! Please! Put me down!"

He reluctantly brought her back to the floor.

She quickly pulled her robe closed in front. With a flushed, aroused face, she told herself, That just didn't happen! We're erasing that from the memory banks!

He gave her another victorious hug. "Mom! You have no idea how happy this makes me!" He loved the feel of her enormously spongy boobs against his chest, especially since he'd just been able to see them bouncing completely out of her robe.

Julie smiled at her happy son. She thought, It's cute how excited he is at the possibility of breeding me, but we both know it will never happen. There was no way my husband would ever go for such a thing. I guess I've been going too far with the flirting, and encouraging him too much. I need to be more careful. Especially with this stupid robe! She blushed from thinking about how she's just fully exposed her massive breasts to his gaze.

She warned him, "Don't get too excited, Sweetie. You haven't talked to your father yet. We both know there's no way in hell he'll agree, and you're probably going to get in serious trouble just for asking!"

Kyle was smirking. "Maybe so. But if he agrees, can we start tonight?!"

"If he agrees, I'll die of shock." She smiled. Her heart was still racing, and her pussy was getting quite wet. She had to admit that his openly admitted desire to fuck her was a big rush, and the fantasy of Jim giving permission was an even bigger thrill. She knew she'd be secretly masturbating to that idea for quite some time to come.

"But if he does, can we?" Kyle pressed.

"If your father agrees, we'll sit down tonight and talk," Julie said. Swept away by his enthusiasm, and her own secret lust, she daringly added, "You know how much I want another baby. I guess you could say I'd agree to just about anything to make that happen, if it wasn't actual cheating."

"YESSSS!" He pumped his fist in the air. He was over the moon. He very nearly had a spontaneous orgasm on the spot, thanks to those encouraging words.

Kyle smiled to himself confidently. He thought, Ha! I know for a fact that having Mom's ankles propped back on my shoulders as I eagerly fucked her hot cunt is about to become a reality! I know it because I know something about Dad that Mom does not! Dad has made a BIG MISTAKE! It's about to cost him dearly! But his loss is my gain!

CHAPTER 2

It was three o'clock in the afternoon. Kyle knew just the time to be at his father's office.

Jim had his cock buried deep in the tight young pussy of his sexy secretary Dora, when his son barged into the room.

The partially naked blonde slut pulled up her panties and ran from the office into another private room, embarrassed as hell.

Jim just stood there in complete shock as his own son glared across the room at him. Then he remembered to hastily tuck his penis away and zip up his pants.

"Havin' fun, Dad?" Kyle asked. He'd already secretly taken some photos of the adulterous sex session, then put the camera away in a safe place so Jim wouldn't get the idea to try to steal it before he could make copies.

"Kyle, I... I was just..." Jim couldn't think of any excuses. He'd been caught red-handed.

It was the first time Kyle had seen his father's penis as it slowly went flaccid, before it had been tucked away. He silently chuckled at how small it was. He was anxious to see how his mother would react having a cock over four inches longer than her husband's plowing her depths. Not only was his dick longer than his father's, it was a great deal thicker, with fat bulging veins and a huge purple knob.

"Relax, Dad. I've known for a long time now." Kyle lied by adding, "It's cool. I don't really mind that much. Sometimes, temptation gets to be more than one can resist, doesn't it?"

At least Kyle honestly understood the sentiment behind that last comment. His own temptation to fuck his mother had grown so great that he was driven to blackmail his own father. He didn't even feel that guilty about it, because it was as if he had no choice in the matter. His libido was in total control.

Jim felt miserable. The guilt was hitting him like a sledgehammer. "What about your mother?! Oh God, please tell me you haven't said anything about this to her!"

"Don't worry, Dad. Mom doesn't ever have to know about this, but in order for things to stay that way, you're gonna have to do a little something for me," Kyle said with a grin.

"Okay... what do you want?" Jim asked. He'd taken his tie and jacket off for the fucking, and started to put them back on.

"Your permission," Kyle said with a smile.

The horny son went on to explain the whole idea of how he could help Julie get pregnant.

Needless to say, that didn't go over very well. There was lots of yelling and cursing. But Kyle held all the cards, even without having to bring up the photos he'd secretly taken as insurance.

In the end, Jim felt he had no choice. Besides, he decided that he'd tried for seven years to impregnate his wife and it just wasn't happening. This was their last realistic chance, other than maybe adoption. So at least some good could come of this disaster.

Later that night, Kyle lay on his bed waiting. Jim had been home for a few hours and he and Julie were downstairs talking. Finally, at about 11 o'clock, Kyle heard a gentle tap at his door.

Julie poked her head in. "You still awake, Sweetie?" she shyly asked.

"Yeah, I'm up." Kyle answered. He thought with a snicker, Of course I'm up, and in more ways than one! What teenage boy could sleep when they're finalizing the deal of a lifetime?! A chance to fuck a baby into my own beautiful mother!

Julie came in and closed the door. She was in her silky robe again and the dainty high-heeled slippers.

He sat up in bed. He was wearing nothing but his boxers. The tenting at his crotch was obvious, and almost comical.
