Madge raised her juice-stained face from between Babs' splayed legs and grinned at her sister. She smacked her lips, relishing the last traces of the younger girl's cum.
"You're right. Jake's cock is still hard! Guess we'll have to do something about that, won't we?"
While Babs watched excitedly, Madge lay on her back, her legs drawn up and parted widely. Jake responded to Babs' push on his haunches, and he immediately trotted over to the older girl.
"Fuck her, Jake! She needs it bad! Fuck your cock into her pussy!" Babs squealed.
The big German Shepherd caught the arousing scent of Madge's musky pussy in his flaring nostrils and he whimpered wildly. Then he hovered over her and drilled his hard cock into her waiting pussy.
Babs shifted her position to watch her pet's prick fuck her sister's pussy. Her pussy was drooling with fresh cunt-juice as her dog's swollen cock parted her sister's slick cunt-lips and slid into her eager cunt.
"Whew!" Babs whistled, watching the folds of reddish cunt-flesh being pulled inward by the pleasure of the mighty dog-cock.
Jake eased his cock deeper into Madge's clasping pussy-hole.
"Ohhhh, yeah, yeah, Jake, you got it! That feels great!" the older girl squealed as she slowly rotated her juicing crotch. Her erotic movement urged the dog-cock to enter her cunt even deeper.
Her tight pussy gripped his gigantic prick with a convulsive shuddering of her cunt-muscles. It made Jake growl with excitement as he thrust his cock deeper into the older girl.
Babs watched it all, licking her lips excitedly.
She felt her own pussy responding to the lewd sight, almost as if it were the one being so deliciously fucked by Jake's cock. She moaned and stroked her own tits as she watched her dog hunching his hips and stroking his prick in and out of Madge's seething pussy.
The rutting animal withdrew his prick from the girl's wet pussy until only its tip remained in her cunt-lips. Then, with a loud bark, Jake plunged forward again, his furry loins slapping against Madge's crotch.
"God, I love watching this!" Babs gasped, lowering one hand to her own crotch and starting to finger-fuck her aching cunt with two fingers.
Madge clutched the German Shepherd's flanks, pulling him downward as her own ass wriggled upward. Her cunt eagerly embraced his hard cock with a thrilling wet suction.
Babs saw that her sister was panting harshly now, and she guessed that the older girl was going to come soon. Her own pussy was trembling violently about her reaming fingers, and she knew she would soon feel another powerful orgasm.
The younger girl thrust her fingers deeply into her cunt-hole, squeezing them hard with her cunt-muscles. She moaned with excitement, feeling cunt-juice seeping from her cunt. Watching her dog fuck her sister turned the youngster on incredibly.
"Fuck me haaard!" Madge screeched, writhing erotically on the bed.
Babs saw her dog's prick slam hard into her sister's cunt, burrowing deeper. And she saw it withdraw only an inch or so before ramming into Madge again, hard and fast. Madge's hips quivered and jerked.
"God, I'm gonna come now!" Madge screamed, her face twisted with lust. "Here it comes! Yeah! Commmiiinnnggg! Aaaaaah, sooooo good!"
Jake barked and pumped into the orgasming girl hard and deep as he came with her.
"Wow! You're both coming now! I can see it!" Babs squealed, watching the foamy dog-cum backing up out of Madge's cunt and running down the girl's quaking thighs. Babs could also see her sister's pussy-juice pouring from her well-fucked pussy with the dog-spunk.
Jake finished shooting his load and he backed up, withdrawing his prick from Madge's cum-running cunt.
"Ohhhh, that felt good!" the older girl groaned, closing her eyes and struggling to catch her breath.
"Awwww shit, I'm so frustrated! I didn't come!" Babs wailed. "I was going to, but then Jake came and stopped fucking you. And I didn't get that extra thrill I needed to push me over the edge!"
Madge propped herself up on both elbows and gazed down at the dog who had just fucked her. Then she grinned.
"Looks like Jake's got just what you need to give you that extra thrill so you'll come."
"What? What do you mean?" Babs asked, looking at her sister with a puzzled expression.
"Look at his cock!"
"His cock is still hard! This dog is amazing!" Babs cried excitedly. "Now he can fuck my ass and make me come."
"You're gonna let Jake fuck your ass?" Madge asked dazedly, beginning to sit up now with renewed sexual interest.
"I'm not just gonna let him ass-fuck me, Sis," Babs said thickly. "I'd beg him to do it for me! You have no idea how good it feels to have that fat dog-cock up your ass! Now, you can help me get ready for that dog's cock."
Babs lay face down on the bed and spreading her legs wide. She felt her little asshole puckering between her trembling ass-cheeks as she thought about being fucked in the ass.
"What do you mean? How can I help?" Madge asked, eyeing her sister's asshole hungrily.
"I need you to get my little asshole all nice and wet for Jake's cock. That way, he'll be able to fuck into me faster and easier and it won't hurt so much either."
"But what should I use to get your ass wet? Should I get the jar of Vaseline from the bathroom?" Madge asked naively.
"Well, we could do it that way. Or you could use your tongue," Babs said, grinning.
"Oh wow! I hadn't thought of that! Yeah, let's do it that way!" Madge said, kneeling behind her sister's ass.
Her head lowered and her little sister whimpered with pleasure as she felt Madge's wet tongue beginning to bore into her tight asshole. It wriggled and twisted its way in.
Babs felt the wetness of her sister's saliva soaking her asshole. The tongue in her ass grew more demanding, moving deeper inside and wriggling and circling about lewdly, arousing Babs powerfully.
Instinctively, Babs' hips pushed back, lifting her ass to receive the girl's probing tongue. Every nerve of her sensitive ass-walls responded excitedly to her sister's deep tongue-thrusting.
"Okay, I guess that's enough. I've got your asshole soaking wet now," Madge groaned, lifting her face from between her sister's ass-cheeks.
"Thanks, Sis," Babs said, laughing softly at the note of disappointment in the older girl's voice.
Madge reluctantly moved away from her sister's ass and sprawled next to her on the bed, stroking her wet pussy while she prepared to watch the German Shepherd ass-fucking the younger girl.
"Okay, Jake!" Madge said thickly. "She's all yours now. Fuck her ass!"
Jake barked and moved rapidly between his mistress' widely spread legs. Babs reached behind her with a little moan and gripped her ass-cheeks in both hands, opening them up lewdly to the dog's cock.
Jake moved forward until the slitted tip of his prick was pressed against the little circle in the cleft of the girl's trembling ass. Then he pressed down, whining at the same time.
"Ohhhh, yessss, Jake, fuck my tight little asshole!" the young teenager cried.
Her body jerked and her legs stiffened as she felt the big, throbbing head of the animal's cock popping past her outer ass-muscles. The huge prick slipped easily on into her asshole.
"Lucky dog!" Madge said, flicking her lips excitedly as she watched the thrilling bestial action wide-eyed. "Your little ass is just made for fucking!"
Suddenly, unable to stay out of the wanton act taking place before her, Madge scrambled to her knees and crawled over behind the big German Shepherd. As Jake shoved his prick into Babs' trembling asshole, Madge shoved her tongue into the crack of his doggy ass, finding his asshole with one skillful lick. She bored the tip of her tongue into the animal's asshole, and Jake growled with pleasure as he finally shoved his cock full-length into Babs' horny asshole.
"Yesssss! Aieeeee!" Babs screamed.
She squeezed her strong ass-muscles around her pet's invading prick. The big dog-cock felt as large and thick as a battering ram inside her ass. It was hot and thick, and pulsing with animalistic desire.
Jake whimpered as he began to fuck the young girl. He withdrew his cock from her hot, lewd ass-grip, until only his bloated cock-head was trapped in Babs' spasming clutch. Then he eased his fat prick in again, creating friction against her tightening ass-walls and sending thrills through the teenager's body.
Babs moaned excitedly. Her ass responded to the steady pistoning of her dog's prick with increasing pleasure. She felt a hand moving beneath her belly.
"Yeah, go for it, Madge!" she cried, lifting her hips and allowing the older girl's fingers to find Babs' pussy-slit. Madge dipped her fingers into Babs' pussy, stroking it hard from the first moment.
"Ohhh, yesss, it feels soooo good! Fuck my ass, Jake! Rub and squeeze my pussy, Madge!" Babs squealed.
Jake rammed his cock home and began to fuck his mistress with a steady pumping movement. His cock slid in and out of her asshole with increasing pressure, each pumping fuck-stroke harder and deeper than the one just before it.
Meanwhile, Madge was massaging her little sister's clit. She thrust two fingers into the wet fuck-hole of Babs' pussy. At the same time, Madge continued to lick and suck on Jake's exposed asshole. Hearing the lewd wet sounds, Babs turned on even more.
Jake barked excitedly as he continued to fuck his mistress' ass. He felt Madge's tongue shoving in and out of his ass, and his entire body quivered.
"Ohhhhh, God, this feels sooo fuckin' good!" Babs cried.
The big dog-cock moving in and out of her ass seemed to blend with the caressing and thrusting fingers in her pussy. She moaned, her pussy spewing out a steady stream of cunt-juice. The thick cunt-sauce ran into the crack of her ass, too, where it soaked the animal's rutting prick.
Babs worked her ass up and back to meet her dog's steady cock-thrusts. She tightened her ass-muscles before letting him withdraw, only to drive inward again, hard and deep.
"Unnggghhh, yesss, fuck me haaard, Jake! You're fucking my little ass soooo Goddamned good!" she cried lustily.
Jake barked, as thrilled by the sound of lust and pleasure in his mistress' voice as by the obscene ecstasy of her tightly squeezing ass-muscles around his prick.
"Yeah, keep fucking me hard and fast until we both come, Jake!" Babs hissed between clenched teeth. "Ooooh! And your fingers are fucking my cunt so fantastically, Madge! Keep doing that! And rub my clit harder! Both of you – make me come!"
Jake bent the top part of his body over the girl's naked ass. His hips pounded his engorged cock into her clutching ass.
Madge continued to strum the younger girl's clit with one finger while thrusting two fingers in and out of Babs' clenching pussy-hole.
Jake's prick suddenly lurched wildly against the walls of his mistress' ass.
"He's gonna come!" Madge cried excitedly, her mouth still pressed against the dog's asshole.
"Yes! I know! I feel his cock jerking all over inside my ass! I can't wait! I want to feel his dog-cum shooting up my asshole!"
As the dog's thick cum exploded into his mistress' ass, Babs' own orgasm blended with his in a climax which left the girl gasping with pleasure. As waves of bestial orgasm crashed down on her, Babs felt her pet's jism continuing to spurt deeply into her convulsing ass.
Madge groaned against the dog's asshole. She stabbed the full length of her tongue deeply into his asshole, feeling it shudder uncontrollably against her mouth as the animal continued to come.
Suddenly, Madge felt her own pussy explode in orgasm. She wrenched her mouth away from Jake's quivering ass so she could scream loudly as she came, her fingers still fucking in and out of her sister's climaxing cunt.
A short while later, Jake was asleep, his cock finally having gone soft. He was curled up in a ball in the middle of the big bed, with the two teenagers on either side of him.
"Well, looks like he's out of commission for now," Madge said sadly.
"Yeah, guess so," Babs sighed. "But Jake's entitled to a rest after everything we put him through. Let's take a little nap ourselves. Then, by the time we wake up, maybe his cock will be hard again, and we can have some more fun!"
