Don Scott: Sisters hot for fun

She felt the cockhead pushing hard against the back of her mouth. Marcy squeezed her eyes shut, fighting against the throbbing sensation in her throat, pushing her face harder over the cock.

When the pricktip slipped past her tonsils, Marcy's neck swelled out visibly with the thickness of her brother's incredible prick. She mewled softly, opening her jaws as wide as possible, chewing down the shaft of the cock as the fleshy pricktip drove deeper and deeper down her throat.

Sam groaned softly, watching his prick sinking between the big-titted blonde's pink lips. He had known very few women who could deep throat his ten-inch cock and he was hoping like hell that he was about to know one more who could swallow everything he had.

Marcy had just a couple inches of the cockshaft still sticking out of her mouth when she felt the cockhead begin flexing and pulsing in earnest. She could sense that Sam was about to erupt in a fountain of cum. With all her energy and will power she tossed her lovely face over the huge prick.

"Uh! Ohhhhh! Can't… can't holdback!" Marcy's lips encircled the base of her brother's prick as the vibrating became more powerful. She could feel Sam's hairy balls against her chin. His balls pulled up between his thighs as Marcy's nose became buried in the curly, thick bush of hair that sprouted above Sam's fat, fiery prick.

The first blasts of cum started only a second or two after Marcy had sucked all ten inches of the cock into her mouth and throat. Hot, sticky cum raced through the prick, gushing out of Sam's balls, spitting from his massive cockhead to wash straight down the teenager's clenching, straining, burdened throat.

"Awwwwwww!" Sam groaned as his balls shook between his powerful thighs, jetting out his rich, pungent cum down his sister's throat.

He entwined his fingers together behind her head, holding her face against his crotch, forcing her to continue deep-throating all of his prick as he came.

Marcy wrapped her arms around her brother's waist, shivering on her knees as cum spewed down her throat. She thought her nose was going to be crushed because he was pulling her so hard against his shivering body. It filtered through Marcy's mind that she would drown on the cum that Sam's balls were jetting out.

Her lungs ached with their need for fresh oxygen. Her big, firm tits trembled on her chest, the rather small, pink areolas a darker color with the lust that sizzled through, her veins, the nipples hard and fiery.

Finally, only when the need for oxygen put Marcy on the verge of panic, she pushed herself firmly away from Sam's body. His huge, red-hot prick slipped out of her throat. She kept her lips wrapped tightly around his cockshaft, holding the pricktip in the warmth of her mouth, swirling her tongue around the knob as a few final weak spurts of cum spit gently from her brother's nearly empty balls.

"Mmmmmmmmm!" the horny teenager moaned soulfully, finally getting to taste at least some of the salty cum that her brother had to offer.

Marcy nodded her face over the end of Sam's cock a couple more times before finally letting the pricktip slip out of her mouth. She looked up into his face and was pleased with herself when she saw his expression of absolute satisfaction in his eyes.

"Do you think Papa will be pleased with me?" Marcy asked a bit sarcastically, knowing that no sane man could shove his cock in her mouth without knowing the extremes of pleasure and lust.

"Yes, Marcy, I'm quite certain he will be." Sam leaned down and tweaked one of Marcy's nipples. "Come on now, get to your feet. I'm not superhuman, after all."

Marcy giggled as she looked at Sam's prick. It was glistening from her mouth, shiny and clean. She hadn't missed a single drop of his precious cum.

Smoothing her T-shirt over her tits once more, Marcy got to her feet, tucking the tails into her tight-fitting jeans.

"You really think that if I throw Papa some hot sex…"

"The best fucking and sucking he's ever known," Sam said quickly.

"Then he'll forget all about marrying that dumb cunt he thinks he's in love with?"

"I'm positive of it." Sam turned Marcy toward the door and patted her ass firmly. "Now get out of here and figure out how you're going to seduce Papa. You haven't got much time!"

Marcy stepped into the bedroom she shared with her younger sister Loni. She wondered if she should tell Loni that she'd just given their brother Sam a blow-job.

Though the girls were close on an emotional level, that was where the closeness ended. They didn't look alike. They didn't act alike. And they never – never ever – talked about sex.

Marcy sometimes wondered if her little sister was still a virgin, even though Loni had scores of young boy friends who were always taking her out for dinner or to a movie.

"What's new?" Loni asked, leaning close to a mirror to apply mascara to her eyes.

"Nothing much," Marcy replied, feeling a little guilty for lying to her sister.

Whereas Marcy was something of a tomboy, Loni was the height of femininity. She always wore dresses or skirts and she never wore jeans. Where Marcy slept in panties and a T-shirt, Loni had scores of frilly, feminine nighties.

Marcy sat down on her bed, watching her sister doing her face. Finally, forcing the words from her mouth, Marcy began explaining to her little sister how it was important that their father didn't marry his intended bride. When she finished, Loni was crying softly.

"Oh, Marcy! What are we going to do?" Loni said softly, a trickle of tears moving down her cheeks. "I know you're right. You're always right about these things." She dabbed her eyes with a Kleenex. "Earlier today I walked into Papa's study and do you know what I saw? I saw that… that woman checking into Papa's bank records!"

"She's no good for him," Marcy said, her tone now strong and commanding.

"But what can we do?" Loni implored, her eyes filled with tears of concern.

"We can change Papa's mind, show him that he's not thinking straight, that he's not using his mind."

"But what can I do to help?"

Marcy bit her lower lip. She wanted to tell Loni to dress up in her most beautiful clothes, find Papa, and fuck him until he couldn't stand straight. But, of course, she couldn't say that to her sister.

"You've got to think of something, Loni. You're a woman. The only reason Papa thinks he's in love is that that woman has blinded him. You've got to make him see the truth. Use your own…" Marcy paused for effect, feminine wiles. You know how to dress right and act right so that boys take notice of you. Now you've got to make Papa take notice of you?

"I see," Loni replied quietly, her eyes clouding over as she fell deep in thought. "I think I see what you mean."

Marcy stepped into the small room that constituted Papa's office. Her cunt was hot and juicy and ready to get fucked. Giving Sam the blow-job had turned her on and now she needed to feel a big, hard prick stabbing deep into her body, spreading her cuntlips and rubbing against her throbbing, tingling clit.

Instead of finding Papa, as Marcy had hoped, she ran into Luke, her older brother. He looked a little like Sam, only he didn't have Sam's moustache and he wasn't built quite as powerfully as Sam.

"Hi," Luke said, his eyes going straight to Marcy's tits, which were straining against the skin-tight T-shirt. "What are you doing?"

"Looking for Papa."

Marcy couldn't help but notice that sly smile that played across her brother's mouth.

"Have you been talking to Sam?" she asked. Luke nodded his head. Marcy saw that he wasn't even trying to disguise the direction of his lusty stare.

"And I suppose he told you… everything." Again Luke nodded his head. But now his hand was at his crotch as he fondled his prick through his slacks.
