"Yes!" Gail screamed at the top of her lungs. "Yes, I love it! God, yes, there's nothing I love more than feeling Scotty's hard cock up my twat!"
Scotty barked as his mistress cried out her pleasure. He could feel the tight clasp of her young cunt muscles around his pistoning prick. His entire body shuddered with ecstasy. He fucked his cock in deeper until it was buried up to his balls. His loaded balls were slapping lewdly against her ass crack.
"Yeah, yeah, Scotty, you're doin' it to me good, all right! Keep it up, baby, keep fucking your Gail," the young teenager purred. She thrust her pussy wetly up against his loins, meeting each of his hard cock-thrusts with a pussy-thrust of her own.
"Don't stop, Scotty! Keep fucking me just like that! God, it feels good!" she wailed tearfully.
"Don't worry, bitch," Biff laughed. "That dog ain't about to stop fucking you 'til he dumps his whole load of cum up your hot little cunt! It'd take a crowbar to pry him out of your pussy now!"
Gail glanced over at her brother and gasped at the heady sight of his fist flying up and down his own hard-on. She knew that her little cunt would gladly welcome the boy's cock. But first she had to finish fucking with Scotty. The dog's cock always came first for the horny youngster.
Biff jacked his prick harder and faster, loving the sight of the Irish terrier fucking his little sister. He could hardly wait to ram his own cock up her tight, juicy cunt.
"Fuck her good, Scotty! That's the boy! Fuck that little bitch real good and hard!" he yelled.
Her brother's obscene cries thrilled the young girl. She could feel her pussy pouring out even more juice as her dog fucked her furiously. Scotty was panting harshly now. Little growls of pleasure were coming from deep in his throat. His eyes were bright and unfocused. He barked now and then as he savagely fucked his entire cock in and out of his mistress' tightly clasping pussy.
"Fuck her, boy, fuck her," Biff chanted as he began to come.
Suddenly, Biff was ramming his orgasming prick down Gail's throat before she even had a chance to prepare herself. She choked for just a second or two. Then she quickly recovered, and she moaned with excitement. She opened her mouth widely, working her lips and inner cheeks and throat muscles around her brother's cum-spurting cock. She felt the load of heavy cum cascading down her throat, and she moaned again.
Scotty howled excitedly, as if knowing that something exciting was going on between Gail and Biff.
"Swallow it all up, baby," Biff panted as his cock continued to shoot wad after gooey wad of hot jism down her throat.
As the young girl swallowed frantically, trying valiantly to keep up with her brother's onslaught of cum, she came hard. Blast after blast of sweet, thick jizz hit the back of her throat as her own powerful orgasm washed over her in gigantic waves. Her entire body trembled with the sheer impact of her mighty climax.
With a groan, Biff slipped his softening cock out of his little sister's mouth and sat next to her on the bed. He turned his attention once again to the erotic sight of the aroused dog fucking her harder and harder.
"Ohhhh, Scotty," Gail moaned, licking up the last few drops of her brother's cum-load from her wet lips. "Fuck me! I just came-but I need to come again! And I want you to come, Scotty. I want to feel you coming and filling up my whole pussy with all of your dog-cum!"
Scotty was delirious with bestial lust. The feel of his mistress' tight pussy squeezing around his cock, and the sound of her animalistic cries aroused him beyond belief. He heard her lust-thickened voice calling his name out over and over and he whined, his cockhead flaring deep inside her even more.
"Come, Scotty! Come inside meeee!" Gail cried suddenly as she felt another orgasm beginning to wash over her.
Scotty howled as he began to come. He felt his mistress' strong cunt muscles squeezing his embedded prick so hard that it hurt him a little. His pleasure intensified as his jism shot out from his cocktip, mingling lewdly with the girl's hot cunt cream.
"Ohhhh, yesss, Scotty!" Gail cried, feeling her dog coming inside her. "I feel it! I feel you coming up my pussy! Shoot it all! Don't stop 'til you've filled my cunt with all of your cum and it overflows! I love it! I love it! I'm coming, too, Scotty! We're coming together!"
More and more juice was released from the girl's pussy. Her orgasm continued as the dog kept shooting his thick, white cum up her pussy hole. Scotty howled and barked and yelped as he and his mistress came together. He could feel her pussymeat dancing spasmodically all over his thrusting prick. The sweet sensation seemed only to increase the cum-load he was pouring into her.
"Whew! You two are really something else!" Biff exclaimed as he watched his sister and the family pet orgasming together, both of their bodies shaking and trembling.
Finally, Scotty's orgasm ended. He fell, exhausted, on top of the still-coming youngster. Gail reached up and out with both arms, hugging her furry lover to her. She could feel her sensitive nipples throbbing against his furry chest. She could feel his prick going soft inside her. She could feel his panting breath warm against her neck and face. She could feel his dog-drool splashing onto her from the tip of his tongue. And she could feel his body trembling in her embrace.
Gail knew that her own body was trembling, too, and that the dog must feel it. Her pussy was twitching with orgasm against his cock. Her thighs were running with streams of cum and pussy juice. Scotty lowered his head to look down at her. Gail raised her own head, sticking her tongue out to lick his.
"You're still horny, aren't you, cunt?" Biff asked with a knowing grin. "Even after fucking the shit out of that poor dog and making him shoot all that cum inside you, you're still horny!"
"Sure," Gail said impishly, eyeing her brother's cock, which was rock hard once again. "I'm always horny. Ready to fuck me now, Biff?"
CHAPTER NINE
"It's my turn now, Gail, and I'm gonna fuck the holy shit out of that hungry little pussy of yours!" Biff growled as Scotty slipped his soft cock from the girl's pussy and lay down on his side, still panting hard.
"Oooh, hurry, Biff! I have to feel another cock inside my pussy again right away!" Gail whimpered.
Biff moved between his sister's legs. He could see her little clit stiffly protruding from its protective pink sheath.
Gail writhed on the bed, impatient to feel the boy's big cock penetrating her cunt deeply. She knew that nothing in the world could equal the thrill of being fucked by her own dog. But his cock was soft now. And, while she waited for it to harden again, Biff's prick would do just fine.
She watched breathlessly as Biff squatted down on his strong haunches.
"Okay, baby, you wanna get fucked? I'll fuck you, all right!" he growled.
"Ohhhh, yesss, Biff, fuck me!" Gail cried-but now her eyes were on Scotty, who was returning her intense gaze.
Biff chuckled and stroked his sister's bursting tits.
"I changed my mind, Sis. You're acting so much like a bitch in heat that I think I'd better fuck you that way. Get up on your hands and knees!" Biff commanded.
"Okay!" Gail cried eagerly as she quickly scrambled to her hands and knees, lewdly waving her ass in the air.
It delighted her to think that Scotty had fucked her in the human position and that her brother was now going to fuck her like a dog. The only thing she didn't like about her all-fours position was that she could no longer see Scotty.
"Over here, boy," she called out, turning her head to look at the dog over one shoulder. Scotty gave a little bark and sprang up, moving around in front of his mistress.
"Good boy," Gail said with a smile as Scotty's tongue lapped out to lick her face.
"Shit, you and that fucking dog," Biff growled. But he knew that there was absolutely nothing he could do about the bond between his sister and the dog.
