Judy whimpered and her lips slowly parted. Her head bobbed down and she inched the Great Dane’s cockhead into her mouth. She took a stow suck and sighed as she discovered that sucking a dog’s prick was even better than tonguing it.
“Yeah! Milk. the fucker!” Barbara wailed, thrilled to the cope at seeing her baby sister blowing a doggy.
Judy’s lips unfurled, clamped around the dog’s cockshaft just behind his prick-knob. She sucked softly and moistly, making slurping sounds. She blew down his fuckrod, then inhaled.
“Ooooooh!” Barbara groaned, fascinated by the sight of her sister’s lips working so lovingly on the brute’s meatrack. Barbara was hungry for some cock and cum, herself, but she was even more thrilled at the prospect of having the big brute unload his cum into her kid sister’s willing mouth and yearned to watch the girl drinking dog slime.
“Ahhhh!” Judy sighed, as the Great Dane moved up and fed more prick into her face.
“You gonna suck him off, Sis?” Barbara rasped. “You want the son of a bitch to shoot in your mouth?”
Judy gulped incoherently, the sound muffled and bubbling around a mouthful of dog cock.
“Yeah? Ohhh, shit!” Barbara wailed. “You wanna swallow the dog’s hot, thick fuck-juice, Sis? Do it! Holy shit! I’m so fucking hot! Suck on that fat cock, baby sister! Milk all the jism out of the dog’s balls and drink it-”
Judy was gobbling merrily away, abandoned to cocksucker’s lust now, going suck-crazy on the dog’s prick. Her lips pulled at his fuck-stalk and her tongue slid back and forth against the sensitive underside of his naked cockhead.
Maybe it was wicked to let a doggy unload his cum in her mouth, but the thought was far too exciting to resist.
She nodded and the motion caused another inch or two of hairy cockshaft to slide into her mouth.
She held it for a moment, then sucked back up to the tip.
“Yeah,” she moaned. “I’ll milk the fucker off, Sis-I want to swallow his cum!”
Barbara squealed in anticipation. She wanted to get involved in the act, herself. She placed a hand behind Judy’s head, holding her face against the dog’s fuckrod. Her other hand folded around the brute’s throbbing cock and she began to skim up and down his hairy prickstalk, stroking from his bails to her sister’s lips.
“I’ll help,” she whispered huskily. “I’ll jerk the fucker off into your mouth, Sis-oh, fuck! I’ll frig his prick while you suck on his cock until the fucker creams-”
Judy gulped and gobbled joyfully, adoring the meaty mouthful and longing for her juicy reward. The Great Dane humped, fucking through Barbara’s fist and into Judy’s mouth. Barbara’s hand pumped up and down rhythmically nudging Judy’s lips on the upstroke and then pulling back to the root of the Great Dane’s cockshaft, skinning his cockhead and making it swell in Judy’s mouth.
The brute was yelping wildly, transported to doggy heaven.
His cock-knob flared in Judy’s mouth and his shaft expanded, throbbing in Barbara’s caressing hand.
“He’s gonna blow his wad-” Barbara wailed.
“Ummmm-pump his fuck-juice into my mouth, Sis!” Judy cried, her lips moving on the slick tip of the dog’s cockhead, then sliding back down his fuckrod and sucking ravenously. The girl was frantic for a mouthful of doggy jism.
As Barbara’s fist dragged back towards the brute’s loaded balls, his naked cockhead swelled in Judy’s lips and throbbed on the arched bridge of her tongue. Pre-cum was washing over her tastebuds, whetting her appetite. She sucked joyfully.
The Great Dane gave a frenzied yelp.
“Here it fucking comes!” wailed Barbara, as she felt his thick fuck-stalk buck violently.
“Yeah! Yeah!” Judy gasped.
She slammed her head down, feeding his prick in, hungry for his load. Suddenly the girl’s willing mouth had become a swamp. The abrupt first spurt took her by surprise and she gasped and gulped and sputtered, swallowing his succulent cum.
She sucked another spurt out greedily. Dog cum overflowed her lips and poured down her chin. Her blonde head ducked up and down on the Great Dane’s massive fucker and jets of jism shot into her mouth and poured down her greedy gullet.
The potent brute was squirting more slime into Judy’s head each time he plunged through Barbara’s fist and into her sister’s suction cup of a mouth.
“Oooooh-I’m swallowing dog cum!” Judy whimpered. “I-umpfff-” her words ended with a bubbling gurgle as another dose of thick fuck-juice flooded her gorge.
“Yeah! Drink him dry, baby sister!” Barbara cried, pumping the dog’s prick with vigor, knowing how much her naughty little sibling must be enjoying the steaming drink.
Sucking sounds, punctuated by splashing jism jets, whimpers and moans, drifted from Judy’s lips. Barbara leaned in to lick up the overflow from the cocksucker’s chin and lips as the dog pumped more slime out.
Then, drained, the Great Dane jerked his spent prick out of Judy’s mouth and hopped down from the chair. Barbara kissed her baby sister on the lips and the two blonde girls panted, swapping tongues and letting dog cum slosh around between their lips.
Judy looked at the dog.
His prick had collapsed and she sighed wistfully.
“That was lovely,” she said. “But I wish the fucker was still hard-I really need a cuntful of dog cock, now.”
Barbara smiled, glancing at the door that led to the kennels.
“Have I got a surprise for you, baby sister!” she said.
