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.
