Mark Jacobs: The horniest family

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 happened the year before. It haunted him still. He couldn't help remembering the day last summer when he and Chastity had almost passed beyond the boundaries of a brother-sister relationship. Whenever he was gripped by uncontrollable fuck-feelings for her, he drifted back in his mind to that lazy weekend at Silver Lake when they had almost taken – and perhaps had taken – the fateful step.

It was the weekend of Chastity's seventeenth birthday. As usual, the Anderson, were spending the special weekend at their place at Silver Lake. Her birthday, falling as it did in the middle of July, always afforded an excellent opportunity for the family to get away from Alton and enjoy some swimming, fishing and hiking at the isolated lake.

Isolated it was. Last in the heavily wooded hills of southern Indiana, the lake was like a world apart and unaffected by civilization. The fact that Rena and Bill Anderson had managed to buy up most of the property surrounding the lake helped protect their privacy. There were only two other houses on the lake, and these were on the side opposite the Anderson cottage.

The cottage itself was really a greatly remodeled barn with the loft retained and converted into bedrooms. The loft was something like a balcony with a rustic wooden railing from which one could look down onto a large but cozy living room. Bill Anderson and his two sons had done all the carpentry work on the place, and Rena and the two girls had done the decorating. The cottage was easily large enough to accommodate several guests comfortably since there were six small bedrooms upstairs and two downstairs. Usually when the family went on these short vacations, they took some friends along. On this particular occasion, however, they were by themselves.

Doug couldn't help but feel the atmosphere of tension that fiat morning. It seemed that Chastity was behaving in a way calculated to flaunt her considerable womanly charms. Her charms were practically unavoidable, no matter how she behaved. Her act at the lake we too much for Doug and Mick to take.

Doug thought it possible that the magic of her seventeenth birthday might have gone to her head. At seventeen, she was at the height of her sexuality and couldn't help feeling it. Doug had felt the same when he had turned seventeen the year before. Fortunately, he had had Marcy Palmer on whom to work off his heightened sense of virility. Poor Chastity was in the woods all by herself with no boys except her brothers.

Everyone got up early that bright Saturday morning and started digging into a hearty breakfast, everyone except Chastity. When she finally did put in an appearance, it was a real show-stopper. She appeared leaning over the railing of the loft, wearing only a wispy negligee and a big smile. Her huge upthrust tits were clearly visible beneath the transparent negligee, as was the light shadow of cunt hair between her legs. She merely stood there looking down, until she was noticed by her mother.

Rena Anderson was accustomed to seeing her children in various states of undress. Nudity was not considered shameful in the Anderson family, as long as there was no lewd intent in the display. Rena was not much bothered by her young and lovely daughter's display.

Mrs. Anderson pointed her out to the rest of the family who immediately joined together in singing "Happy Birthday" to her. She laughed delightedly and took a few bows after the singing had stopped. Then she flew down the stairs, her arms raised and held out at her sides. Doug thought she looked like a sexy angel gliding down the stairs.

Chastity's full firm tits bounced with each step down the stairs. Her long golden hair cascaded over her delicate shoulders, framing her nearly exposed boobs like some unbelievably perfect painting come vibrantly to life. It was pretty obvious to Doug that it would be impassible to sit through breakfast without getting hard and horny over her.

Doug caught a knowing glance, from Mick that told him his brother was going to have the same problem keeping his dick down. They both wished their sister had had the decency to put something more substantial on before coming downstairs, not because there was anything wrong with her near-nudity, but became her young brothers had no defense against her charms.

Sitting there and staring at the soft warm knockers that Chastity presented that morning would be too much for any normal kid to resist, Doug knew, brother or not. Of course it hadn't occurred to Doug that he was sitting there wearing nothing but his underpants or that Mick was wearing only his pajama bottoms. It hadn't occurred to Doug that the sight of his own nearly naked body might turn Chastity on as much as hen did him.

Doug was soon forced to realized just how naked and defenseless he really was. Smiling, Chastity sat down next to him and put her warm hand on his bare leg. The touch lasted only a second or two, but the effect was powerful. It was like an electric shock to him. He almost jumped out of his chair. He hoped no one had noticed his reaction.

"Good morning, everybody! Like my birthday suit?" Chastity asked, addressing the whole family but looking straight into Doug's wide-open eyes.

"It certainly is you!" Rena laughed.

Rena's comment elicited a giggle from everyone. Doug welcomed the break in what for him was an unbearable tension.

Doug didn't know quite what was going on or why. It bothered him considerably, physically at least. It was a losing battle to keep his sensitive dick from stiffening. Chastity sat there with her warm, glowing body turned toward him just enough to give him a clear view of her full young boobs. Her defenseless brother tried desperately to concentrate on something else.

Chastity sat there with the filmy negligee gathered between her legs and pressed against her pussy. The warm, natural fragrance of her cunt wafted past Doug's nostrils. He couldn't resist her, couldn't help looking down at her crotch occasionally in an almost unconscious effort to catch a glimpse of her barely concealed pussy.

Doug looked over across the table at poor Mick, who was trying valiantly not to stare at her knockers. Even his dad seemed to be keeping his eyes on his pancakes a bit too consciously. His mother had a peculiar half-smile on her lovely, patient face. It occurred to him that she might have an idea of what the boys were going through.

"Are we all going down to the beach for a nice morning swim?" Rena asked, obviously trying to break the apparent tension.

"Sounds great, Mom," Doug replied.

"Yeah!" Mick added. "It's gettin' kinda hot in here already this mornin'!"

"Oh? I don't know about that," Chastity said, looking into Doug's eyes, "I like it hot sometimes."

"That's rather obvious this morning, Chastity," Rena said under her breath while rising from the table. "Will you help clear all this away, Dawn?"

Doug wanted desperately to get his pants on. His cock had gotten just hard enough under Chastity's influence to embarrass him if he had to get up from the table. His mother reached over his shoulder from behind to pick up his dishes. He hoped she hadn't noticed his stiff cock sticking up and making a tent in his underpants. If she did notice it, she made no sign to indicate it, unless the way she rested her hand on Doug's shoulder was a kind of sign. He felt relieved at any rate. His relief was short-lived, however. In removing the dishes, bin mother dropped a fork between his legs. No sooner had it clattered to the floor than Chastity had bent down and reached between his legs to lick it up. He pushed his chair back like a shot and sat bolt upright in his chair to avoid her accidental touch. Her arm brushed against his leg, but he was able to move quickly enough to save himself the embarrassment of having his sister feel his hard dick, a hard dick she herself had caused.
