As Gail waited for her brother to fuck her, she stuck her own tongue out, flicking over the animal's furry face, concentrating on his lips and tongue. She could feel hot blood pounding into her tits and her pussy. Her nipples were stiff and swollen. More and more cunt sauce poured from her cunt, trickling on down her quivering thighs.
Suddenly, Scotty hunched down and began to rub his cock against the bedclothes to relieve the ache in his balls.
"Oooooh, Scotty, you've been holding out on me!" Gail cried excitedly. "Your cock's all hard again!"
"Shit!" Biff cursed again. "That damn dog is just gonna hafta wait! It's my turn to fuck you now!"
Gail laughed softly. The young girl knew that there was more than one way for her to take care of her dog's hard-on. She could see Scotty's lust-reddened dog-cock sliding out of its furry sheath. She could smell the heady aroma of his pre-cum as it dribbled from his twitching cum slit.
"Ohhhhh, Scotty," she moaned in a low tone of voice so that her brother could not hear her. Then, she raised her voice. "Hurry, Biff, fuck me now!"
Biff slapped his sister's ass hard several times, leaving his red handprints on her lily-white flesh. He grinned and pushed the throbbing head of his prick into the hairy mouth of Gail cunt. He surged forward, stabbing the first few inches of his cock into her.
"Yessss!" Gail hissed.
Biff groaned with pleasure, loving the feel of his sister's hotly squeezing pussy around his pulsating prick.
"Fuck meeee!" Gail wailed as she began to grind her hips in a lewd fucking motion. She thrust her firm little ass back against her brother's penetrating prick.
Scotty whined, watching his mistress' lust-contorted face. He continued to drag his aching prick against the bedclothes, pausing now and then to rise and lick Gail's face and tits.
"Ohhhhh, Scotty," Gail groaned, feeling the animal's rough tongue scraping deliciously over her tender nipples.
Biff thrust forward, unaware of the sexual play going on between his sister and the dog. He fucked his entire cock into the greased channel of Gail's tight cunt. He felt her strong cunt muscles grabbing at his cock and holding onto it as if they would never release it.
Again and again, Biff fucked his bursting prick in and out of his sister's wet pussy. Gail heard the noisy squashing sounds as her brother's prick rhythmically plowed through her juices. She groaned with excitement.
The next time she felt Scotty's tongue on her face, she opened her mouth and waited. When his tongue touched her lips, she captured it with her lips, sucking it into her mouth.
Scotty whined with delight, his body quivering, his cock growing bigger and harder.
Gail continued to suck on her dog's tongue while her brother dog-fucked her. She licked the tip of the animal's tongue with her own tongue, delighted by the sounds of pleasure Scotty was making.
She knew that Biff was so intent on fucking her from behind that he was unaware of what was going on between her and Scotty. The younger girl thought that was just as well.
She released Scotty's tongue and he licked down her face to her tits. She felt the rough dog-tongue playing over her aching nipples and her cunt tightened even more around Biff's prick.
Again and again, Biff fucked into his sister, not realizing that a good deal of the girl's pleasure was caused by Scotty's tongue.
While her dog licked her nipples raw, Gail moaned and humped back against her brother as hard and fast as she could. She and Biff and Scotty were all beside themselves with lust, all of them concentrating on the orgasms they needed so badly.
"Yessss, fuck meeee!" Gail shrieked, looking directly into Scotty's eyes as if he were the one fucking her instead of her brother.
Her hot cunt juices bubbled around Biff's throbbing cock as the young girl came. She felt Scotty's rough tongue licking over the very tip of one of her nipples, and she shuddered. At that moment, she knew that she could not honestly say which was giving her more pleasure, which was causing her orgasm: Scotty's tongue or Biff's prick.
"Atta girl, come!" Biff yelled, feeling his sister's pussy spasming violently against his deeply embedded cock.
Scotty barked and moved his tongue to his mistress' other tit. As he licked the hypersensitive nipple, he felt his cock growing thicker and aching all the more.
Gail's cunt walls gripped around the shaft of Biff's prick as she came. Biff felt his balls tightening up against his crotch.
"Shiiiit, baby, I'm gonna come, too!" he hollered, continuing to slam his jerking prick into her pussy. "Yeah, yeah, Gail, I'm gonna fill your cunt with my cum! Commmiiiinnngg!"
White-hot jism squirted from Biff's twitching cum slit. Over and over, hot cock cream gushed from the bloated cock-knob, completely filling Gail's cunt with the foamy liquid. Grunting hard, Biff continued to dog-fuck his sister until all of the cum had been drained from his balls.
As she felt her brother's cock slipping out of her pussy, Gail's knees buckled and she collapsed forward, lying face down on the bed. She heard Scotty whimpering and she raised the upper part of her body.
"Whatsa matter, boy? You still got that big hard-on?" Gail asked, licking her lips hungrily.
Just as Gail decided that she would suck the dog's cock until he came in her mouth, Scotty surprised her by moving around behind her. The animal went between her legs, his cold nose prodding against her drooling cuntlips.
"He wants to fuck you again, Gail," Biff said, half-disgustedly and half-excitedly.
He lay down on one side next to his sister, propping his head up on one arm while he began to play with his prick with his other hand. He was facing Gail and Scotty, eager to see what was going to happen next between the insatiable lovers.
Gail eagerly rose to her hands and knees again, quivering in anticipation at the idea of feeling Scotty's hard dog-cock inside her pussy again. And she was glad that the animal was going to fuck her dog-style. Gail was feeling so totally depraved, so wanton, that she wanted to be Scotty's little bitch in heat. If he fucked her from behind, she could feel more like a dog herself, and she thrilled to that feeling.
Scotty leaped up onto his mistress' back and fucked his entire prick into her pussy with one strong movement.
"Yesss, Scotty, fuck me like a dog!" Gail cried.
She tightened her pussy muscles around the animal's prick and began to move back against him. Back and forth, the youngster shoved her ass, forcing her cunt to draw in and out as it sucked tightly around her dog's prick. Her clit stiffened more and more, rubbing against the Irish terrier's hard cock.
Scotty barked excitedly, feeling the strong pull of his mistress' cunt on his deeply-fucking cock. Again and again, he reamed her pussy with his hard prick, fucking faster and harder with each strong thrust.
"Harder, Scotty, let's fuck harder!" Gail screamed, beginning to sob with pleasure and desire.
Next to her, Biff continued to jack his prick, his eyes wide as he watched the long, thick dog-cock fucking into his little sister's juicy pussy.
Gail panted through her flared nostrils and concentrated on the frantic rhythm of Scotty's wild fucking movements. She gasped with joy each time she felt his big cock slicing all the way into her, fucking balls-deep inside her hungry pussy.
"Commmiiinnnggg, Scotty!" she yelled only moments later. "Oh, Scotty, I'm coming!"
Her entire body flushed a deep red. She pounded her ass back hard against her dog's prick just as hard and fast as she could as she came.
"Fuck me, Scotty! Fuck meee! I'm coming so hard!"
Her thick girl-cum flooded around Scotty's throbbing prick as she came for a full minute. She moaned and groaned, her pussy muscles squeezing the animal's cock harder than ever.
Suddenly, Scotty threw his head up into the air and gave an eerie, high-pitched howl.
