Frantically fingering her own swollen clitty, Marci was staring at the goat's juicy little cunt as the goat-pussy squeezed and sucked on her brother's hard boner. The goat's pussy-lips had swollen and turned a dark pink from the delicious friction of his torrid cock.
"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.
"Okay, honey," she giggled as she released his hard cock from her mouth and crawled out from under him. "Now it's time to fuck."
Crouching on her hands and knees, the horny youngster began wriggling her sweet young ass around in front of his nose.
"Can you show the dumb bastard what to do?" she complained to her brother as the goat sniffed and licked at her bare ass without trying to mount her.
"Come on, goat," urged Kirk, lifting the animal up onto his sister's back. "Fuck her hot little cunt."
When the stupid goat didn't move, Kirk gently grasped the animal's hard cock and brushed his sensitive prick-head between Marci's hotly oozing cunt-lips.
"Come on, dummy," he whispered. "Stick, your cock in her."
Feeling the heavenly heat of Marci's juicy cunt against his throbbing hard-on, the big billy goat instinctively lunged forward.
"Ooooooh! Eeeeeeggghhh!" the youngster screamed when the animal's hard cock speared through her hymen. "There goes my cherry!"
The momentary pain only lasted briefly, and once his prick was buried in the snug confines of her cute little unused pussy, she felt a deliciously warm glow spread throughout her body.
With his horns held high and his brown eyes glazed with lust, the handsome, big billy goat began fucking his cock into her with blinding speed.
"Oooooh, shit!" little Marci squealed with joy as the lusting animal further increased the tempo of his rapid thrusts.
The blonde's sweet young tits were jiggling like crazy as the big goat fucked her crouching body. He was practically knocking the breath out of her every time his hard boner fucked into her cunt.
"Yes! Yes!" the girl squealed. "Fuck my cunt!"
Excitedly watching, Kirk could see how much his little sister was enjoying her first fuck even if it was with a goat. Her pretty little face was distorted with lust as she wantonly slammed her cute little ass back to meet every deep plunge of the animal's prick. Helplessly aroused by the delicious friction of the handsome billy goat's hard boner, Marci was creaming all over the slimy length of his bright-red goat-cock, making his prick glisten obscenely with her slippery wetness.
"Oh, you sweet fuckin' goat!" she screamed. "This feels so fuckin' good!"
The horny youngster's face was glowing with excitement as she eagerly took the hard, rapid strokes of the animal's fucking boner. The hard meat of his thoroughly aroused cock was pumping the hot juices right out of her sizzling pussy, the thick cream splattering all over the goat's shaggy belly.
"Oh, so good… so good!" she moaned.
The goat's hips were moving at a blinding speed as he excitedly fucked his throbbing boner into the slick hotness of the teenager's little, gold-fringed cunt. There was almost a lusting grin on the face of the bearded animal as he feverishly fucked into the hotly writhing youngster.
Watching the goat and his little sister, Kirk was more excited than he'd ever been. Nothing had ever turned him on so much in his life.
"Oh,you sweet goat!" cried Marci. "Fuck me faster, honey!"
With the screaming ecstasy still mounting in her fiery cunt, the insanely aroused blonde was slamming her ass back even harder to take the full thrust of his plunging cock.
"Fuck, goat, fuck!" she screamed at the top of her lungs.
This was a scene that Kirk would never forget. Holding his horns high, the magnificent billy goat was humping into Kirk's sister with a savage powerfulness, rocking her beautiful young body, making her firm tits bounce beneath her with joy. Marci was in a state of unequaled ecstasy, and her big brother could clearly see how much she was enjoying herself. Her pretty face was twisted into a wicked grin of lust as she slammed her sweet cunt back around his wildly fucking cock.
"Eeeeeggghhh!" she shrieked in wanton delight. "Fuck it to me, you sweet goat!"
Excitedly watching, Kirk couldn't take his gaze away from his little sister's pussy. The pretty blonde's face was glowing with sexual bliss, squealing with rapture as she took the repeated thrusts of the animal's hard goat-prick. The goat's hips were twitching and jerking with a blinding speed as he feverishly fucked into the slippery slickness of her hot little virginal cunt.
"Oh, sweet pissin' Jesus!" she squealed with delight, raising her deliciously ravaged ass higher to give the wildly fucking goat even easier access to her overheated pussy. "Fuck, goat, fuck!"
Little Marci's beautiful young body was being thoroughly fucked by the rampaging animal's steel-hard boner. The machine-gun rapidity of the goat's deep thrusts was almost more than the writhing blonde could stand. The wanton joy built and built in her seething loins as his blood-red cock streaked in and out of her juicy cunt.
"Oh, you beautiful goat," she moaned. "Make me come! Make me come!"
Feeling herself rushing toward a traumatic orgasm, the beautiful youngster braced her hands against the ground as she slammed her cunt back around the hard, slippery length of the goat's plunging cock.
"Oooooooh!" she suddenly squealed. "I'm coming… coming!"
Marci's orgasmic juices began swirling hotly around the throbbing length of the goat's prick as her cunt muscles involuntarily contracted around his hard cock-shaft. Then, right in the middle of her bell-ringing climax, she felt his hot, wet cum gushing into her well-fucked cunt.
When the exhausted animal finally pulled his limp prick out of the youngster's spunk-filled pussy, Kirk took his sister's hands and helped the pretty little girl to her feet.
"Well?" he asked. "How did you like your first fuck?"
"It was just fantastic," she sighed wearily as she felt the goat's slimy spunk leaking out from between her swollen pussy-lips.
