"Ummmmffff," Dee moaned, sucking the dog's cock as hard as she could, unable to control her raging animalistic lust.
"Yeah, Sis, suck it hard! Make him come. Don't you want all that gooey dog-jizz sliding down your throat! Yeah, suck him hard, you horny little bitch in heat!" Kim screeched as she strummed her clit hard with her thumb while still fucking one finger in and out of her clasping pussyhole.
While she continued to deepthroat the Irish Setter's prick, Dee cupped the furry sac of his balls with one hand, stroking his balls gently but with a steady pressure, hoping to coax the dog-cum out of those balls and into her mouth.
The cock-sucking teenager whorishly puffed her cheeks in and out, increasing the suction around the prick more and more. Dee deep-throated the animal with powerful sucks, working her tongue around.
The dog came, and Dee drank his cum.
Dee felt the cold wet nose of a dog burrowing between her pussy-lips. And the next thing she knew, she was being straddled by a big black Doberman. Dancer quickly moved out of the way.
"Hulk! It's Hulk!" Dee cried gleefully, looking up into the furry face of her beloved dog.
"I know! Guess he heard all the howling out here and decided to check it out," Kim said.
Dee thought Kim's voice sounded a little strange. As Dee felt her little pussy being filled to the brim with Hulk's hard cock, she moaned with pleasure and glanced over to see what was going on with Kim.
"God!" Dee gasped as she saw her sister crouched on all fours in the slimy mud with a huge Labrador fucking her pussy from behind.
All of the other dogs gathered around the twin girls. As Dee looked into the faces of the dogs, she realized happily that it would be a very long time before the animals would allow Dee and Kim to leave the dog pen.
And that was more than fine with her.
