"Fuck her good, honey!" cried Marci. "Just fuck her tail off!"

The horny goat was slamming her haunches back against Kirk, trying to get even more of his big, human cock into her cunt. The animal was bleating loudly with joy as the young man fucked his prick deeper and deeper into her sizzling little goat-cunt.

"Fuck her harder, honey!" Marci hysterically cried as her handsome big brother's hard cock fucked in and out of the animal's hot pussy. "Fuck her good!"

With her naughty fingers clawing at her throbbing clit, Marci was every bit as aroused as her feverishly fucking brother.

"Holy shit!" Kirk shouted. "This is fantastic!"

Marci was wantonly rubbing her hard little tits through the material of her T-shirt with one hand while she frenziedly fingered her clit with the other. Already on the verge of blowing her mind with excitement, the sound of her brother's juice-slickened prick slamming noisily into the goat's scalding cunt was almost more than Marci could take.

"Oh, shit!" Kirk suddenly cried at the top of his lungs. "I'm creamin' her, sis! I'm comin' in the fuckin' goat's cunt! Yeeeeaaaooowww!"

When her brother had finally emptied the last of his hot load into the animal's cum-drenched pussy, he pulled his limp, wet cock out of her cunt.

"Oh, Kirk, honey," his sister sobbed. "I wanta be fucked, too."

"Then try this beauty," he suggested, patting the back of a handsome, big billy goat that was standing next to him.

"How do I get him hard?" she excitedly asked as she quickly pulled off her jeans and panties.

"The same way you get me hard," explained her brother. "Suck on his prick."

Too aroused to care whether it was an animal or not, Marci rolled onto her back beneath his belly. Curling her fingers around his cock-shaft, the beautiful, young blonde raised her head and slipped his cock-head into her mouth. Locking her soft lips tightly around his prick, she could feel his tasty cock swelling rapidly as she sucked. In less than a minute the handsome billy goat had a horrendous boner.
