Heather made her way home through the afternoon rush hour traffic. As usual, her thoughts turned to her son, Chris, and their plans for the evening. As a single mother she'd had these thoughts countless times on a countless number of drives home through the years. Did Chris have ball practice, and was it her turn to drive? What would they have for dinner? Had he finished his homework, and did he have clean clothes for school tomorrow?

Of course, Chris was in high school now and many of those concerns had changed. Until a month ago though, she had never in her wildest dreams, thought that she would be concerned with scheduling sex with her son into her plans. Heather shook her head with a smile and corrected herself. It wasn't whether or not if they would have sex, but when and how many times. Chris was not only handsome with a terrific body; he was also hung like no other man Heather had ever seen. In addition, he was darn near insatiable. There had been many times when Chris had absolutely worn out his older girlfriend, Cindy, and then after dinner and a shower he'd hopped into Heather's bed.

She felt a deliciously naughty thrill charge through her pussy. She knew that part of her arousal was due to doing something so forbidden. But the other part was that son or not, Chris could fill her pussy and make her cum and cum.

She took a long shuddering breath. She couldn't afford to get so turned on right now; she had things to do before she could play. The traffic thinned as she neared home and shortly she pulled into her garage.

"Chris?" she called out as she entered the house.

"In the den," his deep voice answered.

Heather dropped her purse and keys on the kitchen counter and walked down a short hallway into the den. Chris was seated in a large stuffed leather business chair at the family computer with his back turned to the door. As Heather walked into the room Chris swiveled the chair about. He was wearing nothing but a pair of bikini briefs, and his erect cock stuck out of his underwear with its head resting on Chris' washboard abs.

"Hi Mom," he said as he stroked his cock and grinned like a little boy who had been caught doing something naughty but cute.

Heather laughed and shook her head. "What's the matter? Linda still hasn't given in to your charms?" Linda was Chris' partner in a project for their history class. So far they'd done all of the project's work at her home and Linda had made it clear that the project was the only thing that they were going to work on. In fact, Chris had spent an hour with Linda after school that day.

Chris gave his cock a squeeze and a drop of clear precum flowed out of the slit in his cock head. "She's so hot I stay hard the whole time I'm over there. And no... we haven't even kissed." He held out his hand, inviting his mother to come closer.

"Oh no you don't. I'm going to eat a quick dinner and then go over to the school." Heather was going to attend a meet and greet for parents and teachers, and she knew that if Chris got his hands on her body she'd never get there on time.

"Oh Mother, you don't have to go to that thing," Chris complained. "My grades are OK."

"Yes, and I intend to keep them that way. If you're so horny, why don't you call Cindy; she can come over while I'm at the school." Cindy was his steady girlfriend and Heather didn't mind sharing Chris' cock with her. Heather knew that she couldn't satisfy her son's sexual appetite by herself.

Chris dropped his arm to his side and spun his chair back to the computer. "No, she's all pissed with me because I have to spend time with Linda."

Heather stepped up behind her son and rubbed the top of his head through his thick blonde hair. "Oh dear, my poor little boy can't get enough pussy," she said in mock sympathy.

Chris threw up his hands and said, "That's OK. Don't worry about me. I'll just find some nasty porn on the Internet and whack off." He turned his hand to the keyboard and signed on with their service provider. He used the screen name 'Superstud'.

"OK honey," said Heather matter-of-factly as she left the room. As she walked to her bedroom Heather thought, how can I tell my son not to sate his lust with porn on the net when we're having sex nearly every day? Of course, she continued to herself, if we committed even more incest then maybe he wouldn't need to look at the porn. Now how ironic was that?

"Hey Mom," Chris shouted from the den. "Sure you don't want to do the deed? Dad 'n Daughter are on line.

Heather felt a fresh surge of hot blood that flooded into her pussy and weakened her resolve. Last week, during the few minutes it took him to recharge between orgasms, Chris had logged onto the net and entered into a chat room called Dad-does-Daughter. Before Heather could stop him, Chris had struck up a conversation with someone who was using the screen name Dad 'n Daughter. Heather had settled onto Chris' lap and stroked him back to hardness while Dad typed up a storm about how his daughter was sucking him off.

Heather had said, "Oh Chris, that's just some horny old man playing with himself. I doubt that he even has a daughter."

Chris had promptly typed in what Heather had said.

Dad had retorted that he and his daughter were for real and he could prove it. Did they have a microphone connected to their computer? When Chris answered in the affirmative, Dad directed him to a site where they could connect by audio. In a few minutes the voices of Dad 'n Daughter were coming through the computer speakers in Heather's den.

Heather came back to the present. "Are they doing it?" she called out to Chris.

"Hot and fucking," he called back in a teasing voice.

Heather rolled her eyes; she didn't have time for this.

Chris continued to stroke his cock as he listened to Dad 'n Daughter's love play. His cock had been rock hard for a solid hour now. He was so horny he was nearly drunk with desire. The front of his shorts was soaked with precum.

"He's running his tongue around and around my nipple," said Daughter. "And now... ohhh... he's scraping my nipple between his tongue and his teeth... mmm... that's sending little sparks through my pussy," she moaned.

Chris' hand trembled as he moved the computer's microphone closer. "I'm going to have to whack off now; I can't take it any more."

"Yeah I know what you mean," said Dad. "I'm about going to sink my pecker in Daughter's tight pussy."

Chris heard bumping and shuffling sounds as the couple rearranged themselves, and then Dad's voice came back, "Where's Mom? I thought you said she was home."

"She has to go somewhere; I don't think she's going to... whoa, hold on," said Chris as his mother made an appearance at the door. She had stopped in the doorway, one hand above her head, elbow resting on the doorframe, and her other hand was on her hip. She was wearing nothing but a smile and a black lacy demi-bra that made her generous breasts stand out spectacularly.

Heather walked over to her son and made a palm up rising gesture with her hand. Chris jumped out of the office chair and in one smooth motion he swept off his shorts, freeing his huge cock to sway about seductively in the air. Heather took her son's place in the leather chair. It was warm and slick from his perspiration, but she didn't mind. She loved his scent. It was a heady mixture of sweat and tangy shower soap and the sweet, musky aroma of the precum that was dripping from his cock.

Heather scooted her butt to the edge of the seat and Chris took the hint immediately by dropping to his knees and firmly planting his lips on is mother's pussy lips. Heather picked up the microphone and held it close to her lips. "Hi there," she spoke in a low sultry voice. Chris had teased her about that. The low, soft and sexy voice that she used was nothing like her normal speaking voice.

"Hi," said Dad, "glad you could join us." His voice sounded too youthful to be an adult, and for a while Heather had wondered if Dad 'n Daughter weren't a Brother 'n Sister in reality. Eventually though, she had decided that Dad's mode of speech and syntax made him at least as old as she was.

"Yeah, I'm a little behind everybody, I guess," said Heather as she pulled Chris' head firmly against her pussy.

"Mmmmm... let me help," said Dad. "I've got my dick buried in Daughter's tight, hot cunt. You love it too don't you honey?"

"Yes, yes," came the girl's voice over the speakers. "He's fucking me slow and steady now."

Heather rolled her hips, hunching her pussy into her son's face. His tongue tickled her pussy lips while his upper lip massaged her swollen clit. She could feel her sexual tension building and building as she listened to Daughter moan and groan.

"Oh fuck," cried Daughter. Faster Daddy, faster, I want to cum. Please..."

"Now honey, we want to be polite and wait on Mom," Dad said in a teasing tone.

But Daughter didn't wait; she made it perfectly clear that an orgasm was coming. "Uh huh, uh huh, yeah... yeah... uh huh," she chanted and then a high pitched squeal signaled the peak of her climax.

"Oh yeah, do her again Dad," said Heather.

"She'll cum as long as I can keep it up," said Dad breathlessly.

Suddenly, Heather knew it was time. Her pussy had become wet and slick enough for her son's huge penis. "OK Chris," she said breathlessly. "Let's do it."

Chris jumped up and stepped back. He put his hands on his hips and as Heather watched his cock twitched and a glob of precum washed over the oversized head. Heather smiled at her son as she stood and braced herself on the edge of the desk.

"He's going to fuck me from behind now," said Heather.

"Tell me about it," said Dad.

"He's got the head against my pussy lips. Now he's pushing it in. God, that head feels like a big, slick, wet ball being pushed in."

"Fuck yeah," moaned Dad.

Heather continued, "Now his shaft is going in... and in... and in... and in... and now the base is stretching my pussy even wider... and... and now he's all the way in. He's kissing my neck and cupping my breasts.

"Oh shit, yeah," said Dad, and in the background Daughter was doing her squeaky orgasm chant, she was cumming again.

Chris straightened and grabbed his mother's lush hips. He began to move his hips slowly at first and then faster and faster, banging hard into his mom's ass.

Heather loved it when Chris fucked her like this. As his groin slammed into her ass, a shock wave traveled through her body to tickle her clit, and of course his wide cock stretched her pussy so that every nerve ending was stimulated. She even imagined that her g-spot was getting a workout. Or maybe it was just the whole depraved moment of a mother and son having cyber sex with strangers, but Heather found herself cumming almost immediately. "Uhhhhhhh," she groaned out. I'm cumming, Dad... I'm cumming."

"Oh yeah baby," cried Dad. "Cut it loose... cut it loose."

A few seconds later Chris and Heather heard a big gasp and then a long groan that signaled Dad's orgasm, followed closely by yet another cum by Daughter.

Then it was Chris' turn. Heather could feel his cock swell and then throb in her pussy as it jerked and jetted streams of cum that set her off again. Her pussy clenched and urged her son to an even better orgasm. By the time Heather came back to her senses, the Internet connection had been broken, but Chris was still making purposeful strokes with his cock. Heather knew that if she didn't do something, in a minute he'd be hard as a rock and banging her to even higher bliss.

"Chris?"

"Yes?" he answered innocently.

"I'm still going to your school."

"Oh... yeah."

Heather's dinner that night turned out to be a granola bar that she gulped down on the way to Chris' school. She was one of the last parents through the door. A student volunteer gave her a map of the school and a list of the rooms where she could find Chris's teachers. In a few minutes Heather was entering the room to Ms Johnson's history class.

Ms Johnson was busy with some other parents, so Heather took the opportunity to look around. Apparently the kids were studying World War Two, there were several projects showing maps and campaigns and models of various weapons. There was even a mobile of various planes used during the conflict.

"Pretty impressive, isn't it?" said a voice behind Heather.

She turned to see a man in his forties. He had thinning sandy hair and he was only an inch or two taller than Heather, but he had a nice smile and appeared to be in good shape. "Yes, I'm glad I don't have to come up with anything like this."

The man chuckled. "I know what you mean. Is one of these your child's?" he asked as he gestured to the displays.

"Oh no, Chris hasn't finished his yet."

"Chris?" the man asked with raised eyebrows. "Chris is your son?"

"Yes."

The man stuck out his hand. "Linda, his partner, is my daughter. My name's David."

Heather took his hand. "Nice to meet you, I'm Heather. I'm sorry they've done all the work at your house. We have plenty of room."

David shook his head. "It's no problem. They're using my computer. I do design work so the monitor's real big and I have all sorts of software they can use."

"That's nice of you."

"I do have one problem with Chris," said David.

Oh no, thought Heather. What's he done?

"He tends to eat all the snack food in the house," David laughed.

"Sorry about that," said Heather. "He has large appetites." For more than food, she added to herself.

David looked thoughtful for a second and then said, "Speaking of appetites, I have an idea. How about..."

When Heather returned home that night, Chris was in her bed watching television. He began to stroke his cock to full hardness as he watched his mother undress.

"I met Linda's father tonight," said Heather.

"Good ol' David?" said Chris. "He's a pretty good guy."
