Chapter 5

"You little bitch!" Nick yelled with a laugh as he pulled his mouth away from Kay, who had just bitten the tip of his tongue.

"That's just what I feel like today, Nick, a bitch--a bitch in heat. Wanna do something about it?" the young girl asked wantonly.

"Sure. You're a bitch all right, my little bitch," the boy grinned, reaching out and pulling his sister against him once again.

The two teenagers kissed each other long and hard. This time, Kay didn't bite her brother's tongue. Instead, she used her own tongue against his, fucking at it lewdly.

"And I know just how to handle you when you're in a bitchy mood like today," Nick murmured as their mouths parted.

"Oh, yeah? And how is that?" she asked suggestively.

"Can't you guess? A girl who feels like a bitch has to be fucked like a bitch, like a bitch in heat, just like you said," he said, leering at her.

One of his hands crept over her ass and eased between her legs.

"Yeah, you need to be fucked from behind, mounted like a female dog," he said, his cock stiffening with desire.

His hand suddenly squeezed her cunt-mound beneath the fabric of her tight jeans. The sexy young girl shivered, snuggling against him. Her head tilted up and her lips parted. Again, his mouth covered hers. His tongue darted in after her tongue, finding it and licking at it, arousing both of the teenagers more and more.

As their mouths parted, both of his hands caressed the firm cheeks of her ass.

"Okay, bitch, get your clothes off! I want to see you naked and on your knees!" he ordered.

"Yes, Nick, yes!" his sister responded eagerly, a big grin lighting up her face.

She rose from the sofa and stood before her brother as a slave might stand before her master. Her fingers moved to the neck of her blouse and quickly worked the first button free. Nick's eyes fixed on the pink girl-flesh slowly being exposed as the front of his sister's blouse slowly opened.

The last button undone, Kay wiggled her shoulders and let the blouse slide from her body and drop to the floor. Her massive tits bounced freely, trembling with excitement. Nick swallowed hard as he stared at his sexy sister.

The girl's eyes were on his, watching him as he watched her. She could see how turned on he was becoming and that fact turned her on more, too.

Now, her fingers moved to the single snap on her jeans and its zipper. She quickly worked both open and tucked her hands beneath the top of her pants. She shimmied the tight jeans over her hips and down her long, slender legs, then stepped from them.

She was not wearing any panties, as usual, so that now she stood completely naked before her brother.

"Beautiful, baby," Nick murmured, his gaze drifting from her big tits down to the downy, triangular mound of her pussy. "You're one sexy, beautiful chick, you know?"

"Thanks, Brother Dear, and you're a great fuck!" Kay said with a laugh, eager to feel her brother dog-fucking her as he had promised. "Now it's your turn, Nick. Come on, strip!"

With a grin, Nick rose from the couch and, imitating his sister's slow strip, he deliberately worked his jeans down very slowly and then pulled off his jockey shorts. As his eyes rose back to hers, he found her gaze focused on the rising length of cock jutting out from his crotch. Her huge tits heaved and quivered with arousal as she looked at him.

He tore his shirt off and moved toward Kay.

"Kiss it, baby," he whispered huskily.

"Ohhhh, yessss, Nickie!" she moaned, dropping to her knees before him. She opened her mouth and eagerly gobbled up the boy's prick.

Nick groaned. His little sister was always so hot and eager to suck him off and it never failed to thrill him. She chewed at his cock a bit, then sucked hard, her cheeks hollowing deeply under the intensity of her suction. When she pulled her face from his cock moments later, it stood hard and rigid, glistening with the wetness of her saliva.

"Don't forget... you've got a hot bitch in heat on your hands," she said, smiling up at him.

"How could I ever forget?" Nick laughed. "Now get on your hands and knees!"

"Ohhh, goody!" she cried as she dropped to her hands and knees obediently.

The firm cheeks of her ass wagged up at him in an undeniable invitation for him to begin the dog-style fuck he had promised her. And it was an invitation the boy couldn't refuse any more than he could stop breathing.

He eagerly knelt behind her upturned ass, gently stroking the two mounds that quivered in his hands. She moaned softly and wriggled back, pressing her ass lewdly against the palms of his hands. He squeezed hard, kneading the soft yet firm flesh of her ass, an action that brought even more moans from the young blonde.

She spread her thighs wide and Nick slipped his right hand between her legs, cupping her moist cunt.

Nick rubbed his sister's furry cunt-mound, squeezing it teasingly a few times. The girl purred with pleasure, thrilling to her brother's incestuous touch.

Then, with a low groan, the young boy stuck his index finger up into her pussy. It was wet and hot inside and her cunt-juices were flowing like a river. Sucking her brother's cock had aroused Kay so powerfully that she was more than ready to be dog-fucked with no need for foreplay.

He wiggled his finger around in her cunt a few more times and then pulled it out with a wet, sucking sound. Edging closely behind her, he gripped his cock and directed its throbbing head toward the upturned pussy-slit of his sister.

Nick's prick was throbbing with need as he positioned himself behind his little sister, poised before her bloated pussy-lips. Then his hips jerked forward and he slammed every inch of his huge hard cock into her tight, wet pussy.

"Aaaaarrrrgghhhh," she moaned.

The girl's entire body quaked with excitement and pleasure as her pussy gladly accepted the thick prick-rod Nick fed into her. His cock was so big that it filled her all up with its fatness, straining the clenching walls of her pussy.
