Scotty was sitting there next to her, staring down at her. His tongue was hanging out of his drooling mouth, and Gail could feel his warm dog-drool splashing down onto her lower leg. She knew it was crazy to think this way, but she could swear that she read a message in her dog's eyes, a message which told her to go ahead and suck Biff's cock, a message which said that he wanted to watch.
"Unh, ohhh, Biff," Gail gurgled, turning her attention back to her brother's demanding cock.
"What are you waitin' for? Do it! Suck me off! God, Gail, you're driving me crazy! Do you know how sexy you look, lying there all naked with that animal's cum dripping out of your wet pussy?" Biff asked with a lusty groan.
When Gail opened her mouth to respond, Biff shoved his hard cock between her lips. Almost before the young girl had a chance to realize what was happening, he fucked his long, thick prick far down her throat.
She groaned as her lips eagerly closed around the boy's heavily pulsating prick. Her wet tongue came into hot contact with the tiny cum slit, which was oozing out little drops of pre-cum. She moaned with pleasure as she tasted the delicious goo.
Scotty barked excitedly and moved closer to his mistress. The animal was clearly getting off on the sight of the horny youngster sucking Biff's cock. The Irish terrier's prick began to grow hard again, sliding out of its furry sheath.
Gail slid her pursed lips up and down the blood-engorged length of her big brother's cock. Her tongue constantly flicked at the hotly throbbing cockhead.
"Yeah, yeah, yeah, you sexy little dog-slut! Do it! Lick my prick! Suck it! Make me come!" Biff growled. He grabbed the root of his cock in one fist and squeezed it, making his cock as hard as possible.
Now and then, Biff fed his little sister his cock, shoving it into her mouth and down her throat with quick, hard strokes. But mostly he just aimed it at her mouth, holding still. Gail was so turned on that she was doing most of the work. Her head bobbed back and forth, her mouth hungrily engulfing his long, pulsating prick.
Her little pussy was throbbing with fresh waves of lust. She could hear her dog growling and barking with excitement. She could hear him whimpering. Knowing that her canine lover was watching her as she sucked Biff's cock, knowing that the animal was really getting off on it, Gail began to suck Biff off even harder. It really turned her on to be performing for her lusty dog.
The teenaged girl felt spasm after spasm of need racing through her cunt. Her full lips curved even tighter around her brother's big prick. Her tongue played all over the spongy cockhead. She licked and lapped at the hard surface with a hunger that she knew could never be satisfied until she swallowed down every drop of Biff's cum-load.
"Ungh, baby you're really sucking me now… best Goddamned blow-job I ever had," Biff grunted, closing his eyes and swaying drunkenly on his knees.
Her brother's words inflamed the young girl's senses even more. She used her wet tongue to flick at the little slit in the cocktip. Now, Gail lapped at the thickly veined underside. She could feel the wild pulsing of her brother's blood as it coursed through his pounding prick.
"Ahhh, ummmm," she moaned.
"Shiiiit! Your mouth is so hot around my cock!" Biff gasped.
No longer able to restrain himself, he reached down and pulled the girl's head up, forcing her lips farther up over his prick. He removed his hand from his cock and Gail's own hand replaced it.
She grasped the thick cock base, holding it in place while she ran her long, wet tongue up and down the full length of the big trembling prick. She dipped the point of her tongue into the darkly tangled mass of cock hairs, coating them lewdly with her warm, slick saliva. She teasingly nibbled at the sensitive cock flesh. Her wanton actions brought forth groans of unbridled pleasure from the boy, who was already beside himself with desire.
As Gail licked lower to soak Biff's cum-swollen balls with her saliva, her eyes swung over and met Scotty's. She gasped around Biff's prick, seeing the expression of raw lust in the dog's eyes.
I'm doing this for you as much as for Biff and me, Scotty, the girl thought, keeping her eyes trained on Scotty's. She hoped that her dog understood and did not feel left out. Even though I love Biff, you're my most favorite lover in the whole world, Scotty, Gail thought, sending her pet a message of lust and love with her eyes.
Scotty whimpered and began to scoot his furry ass back and forth, deliberately dragging his lust-bloated cock against the carpet.
Her dog's lewd actions made Gail feel even hotter. She began to suck her brother's cock with a vengeance, wanting desperately to make him come.
"Yeah, that's it, little girl!" Biff cried, staring down at the erotic sight of his little sister sucking him off. "Yeah, I'm gonna pop soon, little cunt! Suck haaaard!"
Gail closed her eyes and moaned, continuing to lick and suck on the tasty cock in her mouth. Her thighs were spread widely and little trickles of juice ran out from between her bloated pussylips.
Suddenly, she felt something between her legs. A stab of pleasure contorted her face and she gasped out a muffled groan around Biff's cock.
She held her breath as she felt Scotty's furry paws nudging against the quivering soft flesh of her inner thighs. She knew that the entire slit of her throbbing pussy was fully exposed to the dog's gaze, and she trembled madly with anticipation.
"Ungh!" she groaned, feeling Scotty's probing tongue trailing along the outer lips of her pussy. She could feel his tongue wetting the curling wisps of her juice-soaked pussy hairs, and she groaned again.
She released her breath now and continued to suck Biff's cock. She felt her nipples go achingly hard as the animal's tongue eased her pussylips farther apart. Her hot, moist pink cuntmeat far inside her pussy was vulnerably exposed now. Gail groaned over and over, the sounds muffled by her brother's cockmeat.
The young girl's legs quivered rigidly as she felt Scotty's wet tongue sweeping over the length of her puckering pussy slit.
God, yeah, Scotty! Lick my pussy for me! Gail cried out in her mind. Her mouth was too stuffed with cockmeat to be able to speak. But she knew that Scotty was aware of how much she always turned on to the exquisite feel of his rough dog-tongue scraping over her hypersensitive cunt flesh.
Biff glanced down between his sister's legs, and he laughed with delight at the sight of the dog's drooling mouth burrowing against Gail's wet cuntlips. He fucked his prick down Gail's throat, and her throat muscles clasped at it hungrily.
"Unhhhh," Gail moaned.
She was thrilled to have her dog's tongue in her pussy and her brother's cock in her mouth at the same time. Waves of lust and pleasure shuddered through her. She closed her thighs against the sides of Scotty's furry head, trapping him between her legs.
The Irish terrier growled with excitement. His tongue flicked and licked all over the girl's trembling cunt.
Biff's hands tangled in his sister's hair as he forced her head up even higher from the floor, making her mouth slide all the way down to his prick hairs.
"Ungh," Gail gurgled, loving the sensation of deep-throating her brother's prick while her dog continued to lick her horny pussy.
The lust-maddened animal plunged his saliva-dripping tongue in and out of his mistress' cunt. Her juices flowed into his mouth and Scotty thirstily swallowed them as quickly as they poured over his tongue. He ran the rough surface of his dog-tongue over the girl's bursting clit.
"Aieeee!" Gail cried out around her brother's thick cock. She sucked in her breath sharply, feeling her sensitive little clit being licked over and over again by her dog. She moaned and sighed around Biff's prick.
