"So what," giggled Marci. "I've got a cunt, and you've got a cock. Isn't that all fucking takes?"

"It's not that simple," he explained. "Fucking your own sister is incest."

"I know that," she pouted. "But I want to be fucked."

"Then start out the way I began fucking," Kirk advised.

"How was that?"

"My first piece of ass was with one of our nanny goats," he laughingly explained.

"Are you shittin' me?" gasped the startled youngster.

"Hell, no," her brother replied. "They're fun to fuck. I still fuck a goat once in a while when no one is around."

"Are you suggesting that I let a Goddamn smelly goat fuck me?"

"Why not," he asked. "They have nice, hard cocks, and that's all fucking takes."

"I think you're bullshittin me," complained Marci, brushing her long blonde hair back from her face. "Have you really fucked a goat?"

"Yes, Marci," he answered, looking the youngster straight in the eyes. "I've fucked goats, and I think it's fun."

"Will you let me watch you?"

"When?"

"Right now," she said quickly. "Dad's gone into town and so no one else is here but us."

"Okay," he agreed, thinking it would be fun to fuck a hot, juicy goat right in front of his little sister.

Taking Marci's hand, Kirk led her out behind the barn where the goats were kept.

"Which is your favorite piece of ass?" giggled Marci when they were in the enclosure with the animals.

"That one," said her big brother, pointing to a brown and white nanny goat. "She's got a hot little pussy."

"Now what happens?" giggled Marci, still unable to believe her big brother was going to fuck a stupid goat.

"You'll see," he answered, lowering his zipper and whipping his thick, limp cock out. Flipping his prick around with his fingers, Kirk stepped in front of the brown and white animal who began excitedly pawing the ground with her hooves as she sniffed.
