The horniest family
CHAPTER ONE
'The arc of the apex angle of an isosceles triangle is equal to one hundred eighty degrees minus the sum…'
It was all a crock of shit as far as Doug Anderson was concerned. He looked down at the rip-roaring hard-on the chick sitting directly across the aisle had raised on him. His hard cock throbbed violently between his legs, straining against the material of his tight Levi's until he thought his tipper might tear open.
Concentrating on geometry with a hot bitch, like that blonde within eyeshot was out of the question. Old man Wentzler could take his geometry bullshit and shove it all the way up his fat ass as far as Doug cared. The only triangle that occupied his horny mind at the moment was the one of curly hair that grew around the chick's cunt.
It wasn't the first time this particular blonde had raised a zipper-ripper on him in class. In fact it was becoming a daily occurrence, not that Doug had any objections to a little sexual arousal. His dick could stay as stiff as a board all day and all night, just as long as he had a nice warm pussy to sink it into whenever he felt the urge.
It didn't bother him a bit that a pretty girl was turning him on right there in the middle of class.
He wasn't the type to be embarrassed by a stiff dick, even if the whole clan saw it. What did bother him was the fact that the hot bitch responsible for his throbbing dick and aching balls was Chastity Anderson, Doug's own sister.
It wasn't that Doug saw anything morally wrong with having the hots for his sister. How could he help it? She was the sexiest fox at Alton High and everyone knew it, especially Chastity herself. She could raise a boner on a jellyfish. Doug was no jellyfish. Still, Doug found it a bit awkward to have such ball-busting desires for his own sister. Sometimes he wished Chastity had been born ugly.
Ugly she was not. She was the town's prize piece of ass. Prom the stories floating around town, it could be surmised that half the guys in the senior class had fucked Chastity and the other half wanted to in the worst possible way. Doug knew, of course, that most of the stories were stories and nothing more. He also knew from Chastity's own confessions that she got more than her share of cock. At the moment Doug couldn't help wanting to treat her to a healthy share of his own throbbing prick.
He glanced across the aisle at her. She was up to her usual tricks. She was sitting innocently enough with her long legs crossed, trying, from outward appearances at least, to understand isosceles triangles. Doug knew her well enough to know that her busy mind was on something other than geometry. He noticed soon enough that she was directing her attentions at Rick Davisson, whose cock appeared to be swelling as much as Doug's was.
It amazed Doug sometimes that Chastity always managed to turn on the object of her affections without even looking in his direction. Even in a posture of feigned innocence she radiated hot sex. Doug was only catching the fallout from her attack on his buddy Rick. He almost felt sorry for the guy who was falling under the full thrust of her attack. He fully expected to see Rick at the house that night, wanting to take Chastity out and fuck her royally. Just thinking about it made Doug's rod jerk harder in his pants.
Doug saw her cast a seductive sidelong glance in Rick's direction for the first time. Although Doug couldn't see her eyes at the moment, he guessed that she was sizing up Rick's hard-on and determining the effectiveness of her sexual onslaught. She must have been satisfied with her work, Doug surmised, because she really started pouring it on.
With a subtle yet deliberate movement she reached down and gently stroked her knee, which was already shamelessly overexposed beneath her hot-pink miniskirt. Slowly, seductively, she raised her skirt ever so slightly, exposing even more of her long, honey-tanned leg. She wriggled her ass in her seat just a bit, turning slightly toward Rick, barely acknowledging the boy's presence and the obvious sexual excitement building at his crotch. With a smile on her lovely face she sat there, her delicate hand resting on her leg, bouncing her foot lightly and watching her stud's reaction. Doug knew that Rick could now see all the way to her cunt.
It was the subtlety of Chastity's movements that Doug found so irresistible. Any loose slut, even an old whore, could fasten onto a guy mid turn him on merely by being lascivious. Chastity somehow went above and beyond simple lasciviousness. She had a mysterious way of maintaining her dignity while reducing a victim to slavery.
Chastity had developed a reputation for being loose but not cheap. It was well-known around town that she loved sex and would ball with almost any guy who met her standards. But if she were not well-treated before, during, and alter a screw, she would drop her chosen fucker like a hot potato. Everyone had to admire Chastity for her intelligence, too. There was nothing of the dumb blonde in Chastity Anderson, except when she played the part. She had the highest IQ in the school and was one class ahead of everyone else her age. Doug was hardly in her class intellectually, and he always had the strange feeling that she knew more about him than he did.
It wasn't her intelligence that Doug was thinking about at the moment. He watched her huge, perfectly formed tits rising and falling almost imperceptibly as she breathed. His captive eyes followed the curve of her boobs outlined by the tight material of her soft pink sweater. His mind flashed with images of her bared tits. Chastity was not particularly modest around the house. He had seen her naked countless times. Memories of those times haunted him as they flashed before his mind's eye.
The fullness of her beautiful ass was obvious beneath the clinging material of her miniskirt. He couldn't help wanting to run his hands along the curve of her thigh and probe between her soft, warm legs, until he found her hot cunt. The more he thought about the times he had seen her stark naked, the more he wanted to strip her right there in the middle of class. The more he drank in her perfection, the more he wanted her.
Doug was very close to his younger sister. In fact, with the possible exception of his older brother Mick, who was off in California living in a commune, he felt closer to Chastity than to anyone else, including his parents and even the chicks he fucked regularly.
Doug really didn't know what was at the bottom of the sex feeling he had for his sister, but there was no denying them. As children, he and Chastity had shared all their childhood secrets. As they had grown up and matured sexually, their secrets had gradually become more and more sexually oriented. They thought nothing of sharing accounts of their fucking and sucking experiences. They held nothing back, not even the most intimate details. Of course Doug shared stories with Mick, too, but most of what passed between brother and sister remained strictly between the two of them.
Whenever Doug heard a good story about Chastity from one of the guys at school, he couldn't rest until he had heard the story from her own lips. Surprisingly enough, the bragging of the local high-school packers turned out to be the truth or something close to it. Chastity was not afraid to use her voluptuous body unashamedly for her own sexual gratification, and Doug respected her for her free spirit just as she respected him for his.
Close though they were, their interest in each other had remained, until recently, on the level of simple conversation about their sex lives. In the past few months, however, Doug had begun to notice a definite change in their relationship.
Lately their heart-to-heart talks about fucking had begun to turn Doug on as never before. He couldn't help getting the impression that Chastity, too, was feeling something between her legs when they talked about fucking their mutual friends.
Their mutual attraction had grown too strong to deny and almost too strong to resist. As much as he wanted to fuck her, he couldn't quite bring himself to take steps that might lead to putting the prick to his own sister, even though he knew that she was open to the idea herself. Even for a young stud as oversexed and open-minded as Doug, it was difficult to seriously consider starting something with his own sister.
Doug had watched the situation developing for some time now and realized that he would have to let time and chance decide how far to go with his desires. Perhaps he had already gone too far, at Chastity's urging. It had
