Babs and Madge slept almost two hours. When they awoke, they saw that the big dog was awake, his tail slapping vigorously against the bed. Babs moaned softly when she recognized the sex-hungry look in her pet's eyes. She knew without a doubt that the handsome German Shepherd was ready for more action with the two girls.
"Hey, you were right, Sis!" the older girl squealed. "Jake's got another hard-on!"
"Yeah, so I see," Babs said softly, feeling her cunt growing moist with renewed bestial lust.
"I've got a great idea! Be right back!" Madge suddenly cried, springing up from the bed and dashing naked from the bedroom.
Babs fondled Jake's dog-cock while she waited for her sister to come back. She stroked the entire length of the animal's stiff prick, feeling it pulse beneath her touch.
"Oh, Jake, you're really horny now, aren't you?"
Jake whined in response. He had awakened a short time before the girls had. Now he was filled with fresh energy and a raging desire to fuck.
Babs spread her legs wide, feeling an erotic heat escaping from her cunt.
"You look so sexy like that, Sis!" Madge said with a grin, returning to the bedroom with a carton of milk in one hand and a container of whipped cream in the other.
"Thanks," Babs responded, her eyes on the objects in her sister's hands. "What are those things for?"
"You know Jake," Madge laughed. "He's always trying to get some of our dessert after dinner."
"Yeah, he's got a real sweet tooth, all right!"
"Right. And you know how much he loves milk," Madge said, still grinning.
"Oh, yeah, he loves milk, but we don't let him have it too often. Dad says it isn't good for him."
"Right. So if he could have some milk now, it would be a real treat for him," Madge said, putting the milk and whipped cream down on the table next to the bed.
Then, she sprawled naked on the bed next to the German Shepherd. Babs was still fondling his cock and balls.
"Yeah, it would be a treat all right," Babs said. "But why worry about food now? I mean, I thought we were gonna fuck with him!"
"Oh, Sis," Madge said with a little laugh, "sometimes you are so naive! Don't you get it? We're gonna use this milk and whipped cream to really turn this dog on! We're gonna fuck all right! And these things are just gonna make it more fun!"
"You mean…"
"Yes. After all, if Jake likes to suck pussy, and you know he does – and if he likes to eat milk and whipped cream – just think how much he'll get off on eating that milk and whipped cream off of our bodies!"
"Wow!" Babs said huskily as she took in the full meaning of her sister's words.
She felt her pussy quivering with excitement.
"Lay back on the bed now, Sis," Madge ordered, reaching for the whipped cream.
Babs obeyed at once, eager to find out all about this new way of making it with her dog. She spread her legs and arms wide in a gesture symbolizing her complete surrender to the lust that pounded through her loins.
Madge giggled as she sprayed a small glob of the thick cream on one of her sister's nipples.
"Ooooh! Cold!" Babs said with a little giggle of her own.
Jake watched the two girls with a great deal of interest.
Madge sprayed another dollop of whipped cream on her sister's other nipple. Then, while Babs moaned and whimpered softly, the older girl sprayed some of the whipped cream down from Babs' tits, over her flat tummy, and down to her crotch.
Babs gasped, feeling the sweet cream on her pussy-mound, coating her pussy-fur. She moved one hand down to her cunt, beginning to stroke her clit.
Her sister continued to spray the whipped cream over her body, now on her naked thighs. Babs moaned, thinking that those spurts were like the spurts of pussy-juice pouring out from her aroused cunt.
She continued to pull and stroke her clit, feeling her pussy grow wetter with her own cunt-juices. She spread her legs wider, lost in lust. She heard Jake's excited whimpers and her own moans, and she rubbed her clit harder.
Madge sprayed a glob of whipped cream directly onto her sister's pussy-slit. Then she put the container back on the stand and knelt beside Babs, panting hard with her own lust.
"Go on, boy!" she called to Jake, whose entire body was trembling with sexual anticipation. "Eat!"
Jake moved forward and Babs groaned as she felt the dog's mouth on her, beginning to eat the sweet, delicious cream. Jake started with his mistress' tits. He moved his lips and tongue over one of her nips and licked up the tasty cream, swallowing it eagerly.
Babs heard the dog slurping and licking and swallowing loudly, and the lewd sounds aroused her. Even after her nipple was clean, the horny German Shepherd continued to lick it, his rough tongue scraping it raw.
"Yeow!" Babs squealed but then she laughed, loving the mix of pain and pleasure.
Still kneeling next to her sister, Madge laughed too. She moved one hand down between her legs and began to fondle her own pussy while she watched the erotic action between her sister and the dog.
Now, Jake moved his mouth and tongue to the girl's other nip, starting to lick up the whipped cream there. Jake whined with excitement and pleasure as he lapped up the sweet cream. And, again, he continued to lick the sensitive nip even long after there was no more cream on it.
"Ohhhhh, yesss," Babs hissed between clenched teeth, again feeling the lewd sensation of her pet's dog-tongue scraping her nipple raw.
Jake moved his head down, working his tongue over the younger girl's tummy, lapping up every trace of the thick, sweet cream. As his mouth moved closer to Babs' cunt-mound, to the pussy hair that was thick with whipped cream, she sighed, trembling with anticipation.
"He's almost there, Sis! Just hang on! He'll be licking your pussy in a few seconds now!" Madge groaned, stroking her clit and knowing that she would be coming very soon.
Her body tensed as she tugged on her clit, feeling her own pussy-juices flooding into her pussy.
"Oh, Sis, this was a great ideal! It feels so good!" Babs moaned, writhing beneath her pet's licking tongue.
"Yeah, yeah, I'll just bet it does!" Madge responded eagerly.
The older girl decided that if not that day, then some time soon, she would be the one lying there naked, covered with whipped cream, while the big dog licked it off of her.
"Oh! He's touching my pussy with his tongue now!" Babs squealed as she felt her pet's tongue on her pussy-mound, eagerly scooping up all the whipped cream and swallowing it.
Babs heard her dog whimpering with lust. She knew that her pussy tasted even sweeter than usual, thanks to the thick cream, and she felt glad that she was able to give her loving pet such a special sweet treat.
Jake's tongue was running up and down the length of Babs' pussy-slit now. Babs gasped, feeling his rough tongue against her pussy-flesh. He licked up all the cream and then moved down her thighs. When every trace of whipped cream was gone, Jake sat back on his haunches, smacking his chops.
"You didn't get to come, did you?" Madge asked with concern.
"Nooooo, and Jake stopped licking meeee!" Babs whined woefully. "Do something! I've gotta come!"
"Don't worry, Sis. I'll take care of it!" Madge said with a sudden grin. "Hold your pussy-lips open as wide as you can!"
"What?" Babs asked dazedly, not understanding what her sister had in mind.
"Don't ask questions, not if you want to come! Just do what I say! Grab your pussy-lips with both hands and spread them wide!"
Madge reached for the container of whipped cream again.
"Okay, okay," Babs said, a little offended by her sister's impatient tone.
But she did what she was told, knowing that she could count on her sister to help her come. She gripped her pussy-lips, her fingers slipping on the slick pussy-juice that coated them. Then she spread them far apart.
"Good girl," Madge murmured, squirting a big glob of whipped cream directly on her sister's clit.
"Yeegawwwdd!" Babs squealed, feeling the cold cream coating her clit.
"Now we'll just see what happens when Jake gets a whiff of that whipped cream. Keep your pussy-lips open so he can smell it, Sis!" Madge said, returning the whipped cream container to the bedside stand.
Jake sniffed the air, trying to determine where the tempting aroma was coming from.
"Here, boy, right here!" Babs cried, hauling her pussy-lips even wider apart.
Jake lowered his head and his tongue shot out. He licked the whipped cream all up from Babs' clit and then, just as he had done with her nipples, he continued to lick her hard.
"Commmiiinnnggg!" Babs screeched, gasping with pleasure.
Her entire body tossed on the bed as she came, her pussy-juice flooding her pussy and running down her legs. Jake licked all of that up, too, his tongue moving from her clit down to her thighs, and then back up to her pussy again.
Madge started to play with her own pussy again until she came, too.
"I'm commmimnnggg toooo, Sis!" she yelled, waves of orgasm sweeping through her body.
Jake whimpered lustily, continuing to lick his mistress' cunt. He felt her spasming in orgasm against his tongue and lips, and he whined hornily, his cock growing harder and thicker.
Babs squealed with excitement and humped her pussy up high, arching her back at the same time. He continued to lap at her pussy while the teenager thrust her crotch up against his, her pussy-juices coating his long, pink tongue. Babs wrapped her legs around the animal's furry haunches.
Jake made wet, lewd slurping sounds as he licked the youngster all through her orgasm. Babs squealed and trembled. Madge watched the whole thing, her own orgasm leaving her breathless.
The instant Jake pulled his mouth away from Babs' pussy, Babs sprang up. She pushed her sister down onto the bed, making her sprawl onto her back, as she reached for the carton of milk.
"Your turn, Sis!" Babs cried.
"What are you…"
"No questions! Just lie there and enjoy!" Babs said with a grin, knowing that Jake was sporting a delicious-looking hard-on beneath his furry belly.
Babs raised the opened carton of milk high above Madge's body. She tipped the carton and poured some of the milk onto her sister's tits, then her tummy, and finally her pussy. She poured an especially large amount of the creamy milk directly on Madge's pussy. At the same time, the older girl spread her pussy-lips wide with both hands so that the milk coated her inner cunt-meat and her clit.
"Ooooh! That feels so obscene! I love it!" Madge squealed, tossing and jerking on the bed.
"Do it, boy!" Babs cried, moving back from her sister. "Lick the milk all up, Jake!" Jake's nose quivered with excitement as the dog smelled the milk. He barked once and then moved in between the older girl's legs, swirling his tongue all over her milk-coated nipples.
"Yesssss!" Madge hissed. "That's sooo good!"
"It looks good," Babs murmured, thinking how sexy her sister looked with the rivulets of milk flowing down her naked body.
Babs sat back on her heels, stroking her pussy with both hands while she watched her dog licking the tasty milk off her sister's body.
Jake whimpered with pleasure as his tongue moved from the older girl's tits down to her tummy and finally to her cunt. He lapped up all of the milk covering her cunt-mound. Then, while Madge continued to keep her pussy-lips wide open for him, Jake swished his tongue all over her inner cunt-meat, focusing on her milky clit.
"Yeeeeooowww! I'm coming!" Madge squealed, lifting her ass up from the bed and humping her orgasming crotch up against the German Shepherd's mouth and tongue.
Babs watched her sister orgasming beneath the animal's obscenely licking tongue. She fingered her clit and felt her entire pussy shudder uncontrollably as her own orgasm crashed through her.
"Commmiiinnnggg!" Babs cried loudly as she collapsed forward, across her sister's shaking body.
