"Ungh!" Babs groaned, feeling his big prick swelling and throbbing in her mouth. She sucked still harder.
Just as Babs' own orgasm forced her ass into a writhing frenzy of fuck-lust, she caught the first thick blast of Jake's dog-cum shooting deep into her throat.
She moaned, swallowing it, savoring the delicious taste and texture of the hot dog-spunk.
While Madge fucked her tongue deeply into her sister's convulsing pussy, Babs milked Jake's prick with her greedy lips, letting him drive his cock all the way down her throat. Jake howled and one last spurt of the tasty jizz spilled into Babs' cum-coated mouth.
The thrill of being sucked off while she herself was sucking a big hard dog-cock overwhelmed the young girl. Her orgasm peaked and struck her with intensity.
"Ohhhhh, ahhhhh, unngghhh, yehhhh!" she moaned, trembling all over with the savagely powerful feelings of pleasure sweeping over her.
Thick hot cunt-juice shot out of Babs' tongue-fucked cunt-hole, and Madge swallowed it eagerly. The older girl groaned happily as her own orgasm crashed through her. Madge thrilled to the lewd sensation of her little sister's cunt-meat spasming in orgasm around her tongue.
"Nooooo, Jake, noooo!" Babs groaned disappointedly as she felt the German Shepherd pulling his cock from her mouth.
There was no more dog-cum for the girl to swallow, and when she opened her eyes, she fully expected to see that her pet's prick had gone soft. She looked at it and gasped. Then, she grinned, delighted to discover that Jake's cock was still rock-hard and obviously more than ready for a fuck.
"Oh, look, Madge! Jake's got another hard-on! God, just looking at his fat cock turns me on all over again!"
CHAPTER NINE
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.
