She gurgled around the blood-engorged clit between her teeth. Babs' clit was thrillingly stiff and she felt it swelling even more inside her mouth.
"Yessss!" Babs hissed with pleasure.
Madge's ass rhythmically thrust back and forth, eagerly impaling her cunt on Jake's cock. At the same time, her head bobbed up and down in a steady pace, keeping time with the animal's cock-thrusts.
"Ohhhh, you're licking my pussy sooo good! My clit has never felt so big or stiff before! I'm gonna come soon, Sis! Keep eating my pussy with your mouth! Make me come!" Babs begged.
Desperate for her sister's girl-cum, Madge began to suck Babs' clit again, clawing at her pussy-mound with one raised hand at the same time.
"Aaaarghhhhh! I'm gonna come!" Babs squealed, humping her crotch up harder against her sister's sucking mouth.
"Mmmfff," Madge gurgled as she suddenly felt a flood of hot girl-cum gushing into her mouth. She sucked the young girl's clit harder, sucking and swallowing, sucking and swallowing, eagerly drinking down every drop of her little sister's cum.
Babs groaned with pleasure. She reached up and forced Madge's mouth down harder against her orgasming cunt.
Madge moaned again as she felt her sister's wet cunt-meat filling up her nostrils and mouth. She struggled to breathe, but she wasn't complaining. She loved the lust-filled way Babs was responding to her cunt-licking.
As she continued to suck on Babs' clit, Madge could feel the girl's orgasming cunt vibrating powerfully against her mouth. Her own pussy quivered in response. Babs pumped her hips up and down, face-fucking her sister with her pussy.
Finally, Babs stopped coming and she pushed her sister's juice-smeared face gently away from her aching cunt. Then, she eagerly crawled around behind Madge so she could once more watch Jake fucking the older girl. She hoped she would be in time to see the dog shooting his load of cum into Madge's pussy.
"Make me come now, Jake!" Madge begged hornily. "God, how I need to come! And I need you to come too, Jake! I wanna feel your hot cum inside meeeee!"
She shoved her ass back harder, lifting it higher into the air with the same erotic move. She was offering even more of her gaping pussy to the animal's battering prick.
"Yeah! Make her come, Jake! She needs to come now! And you should come now too!" Babs cried, reaching out and fondling her pet's loaded balls.
Jake pounded his throbbing cock deeper into Madge's wide-open cunt-hole. With his forepaws still locked tightly about her, he drilled his bursting prick ever deeper into her boiling pussy.
"Oh God! I have to come! Or I'll go mad! I swear it! Do it now, Jake! Make me come! Shoot your spunk!" Madge screamed.
Babs groaned, thrilled by the lewd spectacle taking place before her eyes. She squeezed Jake's balls harder, hoping to make the animal come.
Jake barked and thrust his whole cock deeper than ever into Madge's seething pussy. The girl felt the flared cock-tip striking the back wall of her pussy and a mingled sensation of pain and pleasure cascaded through her, triggering her much-needed orgasm.
"Commmiiinnnggg! Finally! I'm coming sooooo good!" Madge yelped, her naked body jerking and twitching wildly beneath the rutting animal as she came.
Her thick pussy-juice spurted out of her cunt-hole, drenching the German Shepherd's prick even more.
Jake felt the girl's pussy orgasming against his cock and he barked and howled, finally beginning to come himself. He continued to pound his shuddering cock into Madge's convulsing cunt as he came.
"He's coming! He's coming!" Babs gasped excitedly, still squeezing the dog's furry balls. "Do you feel his cum, Sis?"
"Ohhhhh, yessss, I feel it! God, there's so much of it! I can't believe how much there is and how good it feeeeels!" Madge wailed.
Jake howled again as he shot wads of thick, white dog-cum into the girl's fucked-out cunt. More and more spunk spewed from his puckering cum-slit and showered Madge's cunt-walls, completely filling up her tiny pussy to overflowing.
"Yes! Yes! Come! Come inside me! I want every drop of your dog-cum inside me!" Madge yelled at the top of her lungs, feeling the peak of her bestial orgasm strike her with full force.
"Oh, wow, I love this!" Babs squealed, watching her dog pouring his white-hot spunk into her sister's orgasming pussy. The lewd sight thrilled the younger girl to the core and she felt her own pussy exploding in another orgasm.
"Ahhh," she sighed, throwing herself onto her back and surrendering fully to the pleasure that shot through her loins as she came. Cunt-juice poured down her thighs from her climaxing cunt, and she continued to watch Jake's pistoning prick shooting off inside Madge's orgasming pussy as she came herself.
Jake whined, and his furry body shuddered violently on top of Madge's back as he shot every last drop of cum into her sucking pussy. Then, he whimpered and pulled his soft cock out of her, his eyes already fixed on Babs' orgasming pussy.
"That was great!" Madge cried, turning around and collapsing onto her back on the bed. She ran her fingers idly up and down her fucked-out cunt-slit.
"I know… watching you and Jake… getting it on… that was a real turn-on!" Babs panted weakly, still coming.
Suddenly, the younger girl felt the familiar touch of her dog's rough tongue licking over her cunt-mound and she groaned with renewed lust.
"God!" Madge laughed, watching Jake and Babs with wide eyes. "Doesn't that beast ever get enough?"
"No!" Babs gurgled as she felt Jake's tongue licking up and down her wet thighs and all over her pussy, lapping up her tasty cunt-sauce. "And neither do I!"
CHAPTER FOUR
A few days later, Babs' parents left town for a few days to visit some relatives, leaving Babs and her sister, Madge, alone in the house with their German Shepherd.
That afternoon, while Madge was at the movies with a friend, Babs sat naked on the couch in the livingroom. She leaned back and spread her legs apart.
"Oh, I'm so horny!" she cried, her breaths growing steadily shorter and closer together.
Babs spread her legs wider, loving the way her pet was watching her. His gaze seemed to burn right into her pussy, making it feel hotter than ever. She felt her budding tits throbbing in synchrony with the pulsing sensation deep in her cunt.
"Mmmmmm," she moaned, running her fingertips over her nipples, which stiffened at once beneath her lewd touch.
The young teenager shivered and her lips parted, her lips moist and red. She closed them for a moment, feeling her nipples growing larger and harder against the soft tips of her fingers.
Still watching his mistress, Jake whined and humped his hardening prick against the carpeted floor.
Babs gripped her stiff nips and pinched them, lightly at first. She moaned with excitement and then pinched them harder.
"Yeah!" she cried, feeling ripples of obscene pleasure rolling up and down the length of her spine.
She felt her cunt-juice dribbling slowly from the base of her pussy, running into her ass-crack. The young girl spread her legs even wider now, loving the feeling of her cunt becoming wet with her pussy-sauce.
Babs saw that her dog had moved closer to her.
"Oh, Jake!" she groaned, lusting for the fat cock that was pulsing beneath his furry belly.
She knew that she could call out for him to fuck her right there and her pet would respond at once, sinking his cock into her horny pussy. But she knew from happy experience that it was that much more fun to delay things a bit and so she continued to stroke herself while the aroused German Shepherd eyed her hungrily.
The teenager pulled at her nipples, still gripping them between her thumbs and forefingers. She pulled them out as far as possible, making her nipples even pointier and longer than usual. She released her nipple-grip and placed her palms over her tit-mounds. She spread her fingers far apart so she could clutch her tits entirely.
