All the rest of that Saturday, Gail fucked and sucked her brother and her dog. Late that night, the three lovers collapsed in a tangled, exhausted heap on Gail's bed and slept soundly until the next morning.
While Scotty waited impatiently at home, Gail and Biff attended church services. They both had a difficult time concentrating on the minister's sermon, but when he began to preach against the evils of the flesh, they sat up and took notice. Gail and her brother exchanged excited glances as they heard the preacher drone on and on about carnal sins and depraved acts. His sermon aroused both of the teenagers until finally Gail moved her hand over to her brother's lap. Under cover of his hymnal, she began to squeeze his growing hard-on through his pants.
By the time the services ended, Gail and Biff were the first ones out of the church, anxious to get home and start some serious fucking.
"Well, well, Gail and Biff," the minister said, meeting them at the door where he always stood to greet his departing parishioners. "It's so refreshing to see two wholesome teenagers like yourselves attending church services. And I hope you enjoyed my sermon this morning."
"Oh, yeah, I'll say!" Gail giggled, rolling her eyes up at her brother. "We got a lot out of it!"
She heard a startled gasp next to her and she looked to see old Mrs. Wynant staring wide-eyed at Biff's hard-on, which was making the front of his pants tent out obscenely. Gail giggled again and grabbed her brother's hand, both of them dashing away.
The youngsters entered their house a few minutes later, still laughing over the incident at church. They were greeted by Scotty, who barked loudly and wagged his tail in greeting.
"God, am I ever horny!" Gail cried, reaching down to pat her dog on his head.
"Me, too! That preacher's sermon was turn-on today!" Biff said, already undressing right there in the living room.
"Oh, great idea," Gail said, watching her brother. And she quickly stripped off her own clothes.
Scotty watched the brother and sister excitedly, his body beginning to tremble, and his prick beginning to harden.
Gail plopped herself down on the living room floor, her eyes moving back and forth from her brother's hard cock to Scotty's prick, which was growing thicker by the second.
The young girl began to make low, animalistic sounds. Scotty moved to her side and lay down next to her. Biff moved to Gail's other side and sat down, looking at her expectantly. With one hand, Gail began to rub Biff's thick cock. She watched the deep slit in its throbbing head as a single drop of pre-cum oozed out. She smoothed the pearly drop across the smooth prickhead while the boy groaned thickly.
"Unnnhh, yeah, Gail, honey, that's it! Rub my cock hard! It's such a turn-on, the way you handle my prick!" Biff grunted.
Her brother's obscene words aroused the teenaged girl even more. With her other hand, she reached out and clasped it around Scotty's pulsating prick. She began to rub that hard cockmeat as she continued to jerk off Biff's enormous cock.
Scotty whined and whimpered with pleasure as he felt his dog-cock growing bigger and harder in his mistress' gripping hand.
With a lewd grin, the excited young girl moved her fists up and down both of the throbbing pricks. She stroked them from their meaty bases up the thick stalks to their broad heads and then back down again.
"You sexy little slut!" Biff growled as his cock sputtered out a thick bubble of pre-cum. "Watching you jerk off that dog… while you jerk me off… what a turn-on!" he panted.
Having both her dog's and her brother's cocks in her hands while she sat naked between them was a real thrill for the little girl. She felt her little pussy drooling out a steady stream of juice. And she could feel her clit stiffly sliding out of its protective sheath.
"Urgh, I'm sooo horny," she purred, glancing first at Scotty's throbbing cock, then at Biff's, while she continued to jerk them both off.
Biff groaned with excitement and thrust his muscular ass up from the floor, shoving more of his prickmeat into his sister's fisted hand.
Scotty shuddered with pleasure and gazed up at his mistress with adoring eyes.
Scotty's prick had risen to full erection under the girl's skillful hand. He growled with lust as she stroked his prick up and down, over and over again. She moved her fist harder and faster with each eager stroke. The red dog-cock was throbbing and more than ready to fuck.
Biff's cock was pounding. It was an angry-looking purplish color. His cock strained hard as it pulsed violently against the palm of Gail's hand. She could feel the big throbbing veins running up and down the full length of both of the meaty pricks in her hands.
"God, Sis, I don't think I can take this much longer without coming," Biff groaned a few seconds later.
Scotty barked, as if agreeing.
"Okay, it's time," Gail said thickly, pulling up on the two cocks as hard as she could.
"Time for what?" Biff asked huskily.
"What do you think?" Gail asked breathlessly, her tits bouncing about as she jiggled in excitement. "I want you both to fuck me now!"
"Wait a minute, Sis," Biff laughed. "Did I hear you right? Are you telling me that you want me and that dog to fuck you… both at the same time?"
"That's what I'm telling you, all right!" Gail said with a little girlish giggle.
Biff grinned and stroked the insides of his sister's silken thighs. Then he slipped his hand beneath the girl's ass and gave it a hard squeeze.
"Oh!" Gail gasped, and then she laughed again.
She looked over toward Scotty and saw that the dog's cock was harder and bigger than ever. At the same time she felt her tight asshole puckering with desire. And she knew that she needed to feel both Scotty's dog-cock and Biff's boy-cock inside her-one in her cunt and one in her asshole.
"Why don't you suck on my cock a little while first, Sis?" Biff asked thickly. He fisted the base of his big prick and squeezed it.
"Mmmmm, good idea, then you can stick it inside me!" Gail gurgled.
And with that, she bent low and licked the head of her big brother's prick.
Scotty whined with lust as he watched his mistress licking the boy's cock. Gail heard him and she reached out blindly with one hand, grasping the dog-prick and rubbing it up and down. Now she had the meaty dog-cock in her hand and the boy-cock against her tongue. She sighed happily, knowing it would feel even better when she had both of those gorgeous cocks deep inside her pussy and her ass.
She stroked her dog's prick slowly, not wanting to make him come just yet, but just wanting to give him pleasure. From the way the furry beast was snorting and whimpering, she knew that she was succeeding in doing just that.
Now, Gail went down on her brother's cock. She had to angle her head and neck just so to take the cock all the way down to its base. But she was determined to slick up the huge rod of cockmeat with her saliva to lubricate it for one of her little fuck-holes.
She drooled a mouthful of warm saliva over the boy's prick. Then she pulled back and looked down to admire her handiwork. Her brother's cock glistened with a layer of saliva mingled with pre-cum. Again, Gail sucked his cock into her mouth, and she sucked it hard. At the same time, she continued to stroke Scotty's dog-cock while the Irish terrier trembled all over with animalistic lust.
Gail licked up and down the full length of the twitching cock in her mouth, paying particular attention to the lust-bloated cockhead. She lubed it up with her saliva.
Her clit was pounding with blood and her thick juices were pouring out of her cunt hole fast and furiously. Her cuntlips were splayed out, swollen and juiced up for fucking. Her nipples ached painfully, harder than she had thought possible.
"It's time," she panted, slipping her mouth off of Biff's throbbing cock. "You fuck my ass! Scotty can fuck my pussy!"
She didn't tell her brother that although she was dying to feel both of her holes plugged with hard cockmeat, it was her little pussy that was crying out for cock the most. And Gail wanted her favorite cock in that tight cunt hole… Scotty's dog-cock.
With Biff's help, Gail managed to maneuver Scotty into position so that he could fuck the girl's pussy while she lay on her side.
Using both hands, Gail spread her pussylips wide and watched hornily as Biff helped Scotty to steer his prickhead into her moist pussy slit. The impact of that pulsating dog-prick into her pussy made the teenager's head spin with bestial excitement.
"Oh, God, yessss, Scotty, fuck my pussy!" she cried.
Scotty caught on quickly. As soon as Biff released him, he gave a strong thrust forward with his haunches, fucking his entire prick into his mistress' cunt.
Gail's little pussy felt completely stuffed with cockmeat. She could feel the dog-cock swelling and throbbing inside her tightly gripping cunt hole.
She rode his prick back and forth a few times, deliberately thrusting her tight little ass in front of her brother, who had moved behind the young girl.
Now that her dog's cock was deeply embedded inside her pussy, Gail was free to use both hands to spread her asscheeks wide apart for Biff. She groaned, feeling Scotty's dog-prick fucking in and out of her snug pussy hole with an easy rhythm which really turned her on.
She exposed her little pink asshole to her brother, who half-lay, half-crouched behind her, hardly able to wait to sink his whole cock into her tight shitter.
"You sexy little dog-slut! You really want me to plug your asshole with my big cock while that dog fucks your pussy, don't you?" Biff growled.
"Yessss, do it!" Gail hissed between clenched teeth.
Biff grinned. He took hold of her asscheeks with both hands and dug into them with his hard fingers. His prick was throbbing violently and his balls ached with desire. He grabbed two big handfuls of Gail's ass flesh and spread the two cheeks wide apart. The little winking eye of her asshole made the young boy drool with barely restrained lust. His piss slit oozed out more pre-cum.
With a low growl, the boy aimed his huge cock down into the smooth valley between Gail's asscheeks, toward her asshole. He gripped his cock at the base and thrust it hard against the tiny resisting hole.
"Harder! Don't give up! You can get it in!" Gail cried desperately, thrusting her ass back and forth to keep time with Scotty's fucking movements.
Scotty heard the lust in his mistress' voice and he whimpered with excitement. He felt her pussy clutching greedily at his cock and he barked, his furry balls churning with their big load of dog-cum.
After a few hard stabs, Biff managed to sink the swollen head of his cock into his little sister's asshole. Her strong ass muscles immediately closed around his hard cock, locking him in place.
Biff grabbed Gail by her waist with one hand and gripped the base of his prick with his free hand. Gail groaned as she tilted her ass up toward her brother's cock, taking Scotty's cock along with her.
She moaned as she felt the big cock shoving up inside her ass. And she purred with pleasure as her dog continued to fuck his own prick in and out of the hot confines of her clutching pussy.
Gail felt a tingling ecstasy all through her body at the joy of having both her shit hole and her pussy hole so thoroughly impaled on the two hard cocks. Thrilling sensations radiated out from her two fuck-holes, making every one of her nerve endings burn and throb with desire and pleasure.
"Ahhhhh, yes, fuck me, fuck me, fuck me!" she chanted, thinking that there was nothing more exciting than having two big cocks inside her at the same time, especially if one of those cocks belonged to her dear doggy.
Scotty and Biff were both fucking the teenager hard. Back and forth they moved, sending their whole pricks into her while she moaned and thrust back against them.
Gail's strong ass muscles clutched Biff's cockmeat in a wet stranglehold, making the boy's mind spin with dizzying excitement. At the same time, she gripped Scotty's pistoning prick with her clasping pussy muscles, and the dog barked in response.
Gail was glad that she was facing her dog. She loved the feel of her brother's cock up her ass. But it was Scotty she wanted to see as they fucked. The dog's eyes were fixed intently on Gail's and she returned his gaze, feeling as if they were becoming one as they fucked on and on.
As before, Biff's cock up her ass was merely a way to turn the young girl on even more, a way to enhance the sexual act she was sharing with her dog. But it was the Irish terrier who was Gail's real lover, and she knew that was the way it would always be for her.
Scotty's furry body shuddered powerfully as he continued to fuck his hard cock in and out of his mistress' cunt hole, which grabbed and massaged the hard prickmeat.
"Ohhhhh, God, yesss, I love it! Both of you… your cocks are so big and hard! And you're both fucking me so good with them! Keep it up! Keep fucking meee!" Gail wailed, tears of pleasure filling her eyes.
Biff chuckled with delight, beginning to ass-fuck his sister even harder with long, deep cock-strokes.
Scotty howled as he continued to fuck the full length of his bloated dog-prick in and out of his mistress' tight cunt hole.
"Yeah, yeah, you two, keep it up, keep it up! I want all of us to come at the same time," Gail moaned.
Biff gripped his sister tighter about her waist and fucked his prick even deeper into her asshole. He and Scotty were both fucking the little girl harder and faster now, fucking their cocks in and out of her with deeper plunges on each stroke.
"Yes! Yes! Fuck me! Harder! Faster! Deeper! Ohhhh, you two big-cocked bastards are making me feel sooo fuckin' good!" Gail screeched, throwing herself back and forth between the two impaling pricks.
She thrust her hips out and forward, taking Scotty's dog-cock up in her pussy to the balls. Then she rammed her hips back and sucked up the full length of her brother's massive prick up her ass. Again and again, she moaned with pleasure. She was thrilled by the lewdly satisfying sensation of having both of her fuck-holes so thoroughly stuffed with hot, hard cockmeat. It made her feel good and warm and loved and very, very sexy.
The fully aroused girl tossed her head from side to side, her long hair flying sexily about her shoulders. She clenched her teeth tightly and groaned continuously now. She had never been fucked this deliciously before.
She moved her hips around in lust-crazed circles, catching the full force of Biff's big cock up her shuddering asshole and then the full impact of Scotty's dog-cock up her twitching cunt.
She could feel more and more juice running out from her cunt walls, thoroughly soaking the animal's hard prick before dribbling down into her asscrack, where it coated Biff's pistoning prick.
She worked Biff's cock deeper and deeper inside her ass, clutching at it wildly with her ass muscles. At the same time, she rode Scotty's cock until she felt its spongy head smacking up flush against the very back wall of her pussy.
Her dog and her brother were both fucking the holy shit out of her now. Gail loved it. She savored each bone-jarring impact as their pricks surged into her fucked-out holes. She wanted them to fuck her brains out. The harder and deeper and faster they fucked their pricks into her, the more the young girl liked it. And the closer she got to coming.
"God, Sis," Biff growled moments later as his prick jerked convulsively against the tight walls of her ass.
He knew that he was about to come. He crammed his huge prick into her ass even harder and deeper than before, then yanked it free. Again, he shoved his prick into her with hard, brutal fuck-strokes.
"Yeah, yeah, come, Biff!" Gail urged, realizing that her brother was about to release his load inside her. "I wanna feel your cum up my ass!"
"Yeah… soon… real soon," Biff panted.
Scotty continued to fuck his mistress' pussy with long, sure strokes, about to come, himself. He kept his eyes fixed on Gail's flushed face, watching the play of pleasure-filled emotions there.
Gail again urged her brother to come. But this time, she used a different method. She squeezed his cock harder than she had even thought possible with her flexing ass muscles, draining the spunk right out of him.
"Commmiiinnnggg!" the boy cried, throwing his head back and groaning with relief.
He shot his cum-load into his sister's ass, holding his prick still inside her. He felt her grinding her hips back into his and he shot more and more cum into her ass until the thick goo began to dribble out, running lewdly down her legs.
"Whew! All fucked out!" Biff grunted.
He tried to pull his drained cock out of his sister's asshole but she was gripping it so tightly that he couldn't.
"Hey, Sis! Let go!" he hollered.
Gail just giggled and continued to squeeze her brother's cock as hard as she could with her ass muscles.
Biff reached out and slapped her hard across her ass, making her entire body jiggle and bounce with the impact.
"Yeoowww!" Gail cried, involuntarily relaxing her ass muscles.
Biff easily slid his prick out of her ass and lay back on the floor, watching his sister as she continued to take the dog's cock deep inside her pussy.
"Now, it's just you and me, Scotty," Gail murmured, looking directly into the animal's glazed eyes. "And it's your turn to shoot. C'mon, boy, I'm ready to come and I want to come with you! Let go, Scotty! Gimme all your cum!"
Scotty moved his head forward and licked his mistress' tits. He went wild, fucking his cock in and out of her clenching pussy.
"Commmiiinnnggg!" Gail wailed, throwing her head back and feeling her whole body tensing with pleasure and relief.
Just then, she felt Scotty's cock exploding inside her, and she trembled with excitement. She reached out and clutched at the animal, which continued to fuck her while they came together.
The orgasming girl threw her lower body forward and back, fucking her little cunt on the dog's pistoning prick just as hard and fast as she possibly could.
"Yes! Yes! Come! Come inside me!" she cried, feeling waves of bestial pleasure cascading through her cunt.
Her pleasure spiraled upwards as she felt the dog's cum flooding her pussy. She was delirious with joy. She felt as if she could never possibly get enough of Scotty's dog-jism inside her.
Scotty howled and barked as he came. His eyes were red. His nostrils were flared. He was panting noisily.
"Yieeeee!" Gail screamed as her orgasm peaked.
She loved the thrilling sensation of having both her pussy and her asshole filled to the brim with hot, thick cum. And she was delighted that Scotty was able to continue to fuck her as he came inside her pussy.
The dog howled again as he felt his mistress' pussy spasming and snapping around his cock. Her hungrily climaxing cunt was eating his cock alive, and he thrilled to the delicious sensation.
"I'm still coming!" Gail shrieked as her orgasm continued to blast through her body. "God, but it's good!"
She felt the thick cum spilling out from her asshole and her cock-stuffed pussy. The creamy stuff dribbled down her legs and splashed onto the floor where it bubbled on top of the carpet.
"Keep fucking me, Scotty! Fuck my brains out!" she wailed.
Scotty looked at his mistress with a dazed expression and continued to fuck her as they came together.
Gail sighed. She knew that she would never again try to win her parents' love. She knew that not only would that be impossible, but that she no longer needed them. She now had the love of her brother… and of her dear, dear Scotty. That was all she needed to be truly happy.
