From that night on, Kirk was finger-fucking his little sister two or three times a day while she was sucking him off.
"Kirk," Marci whispered to him one afternoon when she was up on his bed with him.
"You've fucked lots of girls, haven't you?"
"I've had a few."
"Is fucking fun?"
"Of course it is."
"Would I be fun to fuck?"
"Shit, yes," he said, grinning.
"Then will you fuck me?" she excitedly asked, her eyes glowing with lust.
"I wish I could," he sighed. "But that would be impossible."
"Why?"
"Because you're my sister."
"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.
"Holy shit!" exclaimed Marci when the nanny goat's thick, wet tongue began licking her brother's soft prick.
"That's a good girl," she heard Kirk softly whisper as he unbuckled his belt and dropped his jeans and shorts down around his ankles.
Marci excitedly watched as the goat lovingly licked his balls as well as his rapidly swelling cock. When his prick had reached a throbbing erection, the animal's tongue was feverishly licking up and down the meaty length of his cock.
"God, what a cock-sucker!" cried Marci, feeling the hot juices leaking out from between her legs as she watched the goat eagerly going down on her big brother.
When the goat had licked Kirk's cock to a throbbing hardness, the youth gently turned the animal around so he could invade her juicy cunt from the rear. Having been fucked by Kirk often enough to know what was coming, the goat was trembling with delicious expectation.
Watching her brother guiding his bloated cock-head toward the animal's pink, wet pussy, Marci was surprised at how much the animal's cunt resembled her own. Excitedly rubbing her hot little pussy through the material of her tight jeans, Marci could see her brother's deliciously naked tool slipping in between the shivering, goat's pink cunt-lips.
"Oh, fuck, she's nice and hot today!" panted Kirk as he felt the scalding slickness of the animal's slippery pussy walls closing around his tingling boner.
Seeing how the excited goat was backing up against her brother, Marci realized the horny animal was trying to work even more of his prick into her sizzling cunt.
"Jesus, Kirk!" Marci exclaimed to her brother. "She really digs your cock."
"You're not shittin," he groaned. "This stupid goat loves to be fucked."
After a short pause, Kirk partially withdrew his hard boner and began fucking into the bleating animal with long, rhythmic thrusts.
"Fuck her good, honey!" his excited sister cheered him on.
The feel of Kirk's big, human cock fucking in and out of her snug little cunt was driving the horny goat wild. The animal's entire body was tingling from the delicious bigness of his hard prick.
Marci had never seen anything so erotic as her brother fucking his thick, slippery cock in and out of the goat's girl-like pussy. Naturally the youngster had never seen anyone fucking before, and this lewd action was almost blowing her mind.
At first Marci had wondered how her brother could possibly enjoy fucking a goat, but seeing the ecstasy on his face, she realized how much pleasure he was getting from the goat-fuck.
"That's it, Kirk!" the little blonde squealed with joy. "Just fuck her silly!"
Wishing her big brother's cock was zipping in and out of her hot little cunt, Marci was vigorously rubbing her pussy through the material of her jeans. Becoming more aroused by the second, the youngster pulled her zipper down and wormed her finger through the leg opening of her panties, drilling it into the slick hotness of her itching, dripping little cunt. Excitedly rubbing her erect clitty, Marci stared at her brother's hard cock fucking in and out of the goat's juicy cunt.
"Oh, yes, Kirk!" she squealed. "Fuck her good!"
Excitedly watching, Marci could see that her brother was fucking the wild-eyed goat for all he was worth, his panting mouth gaping open as he stared crazily ahead of him. She could see the juicy pink lips of the animal's frothy pussy sucking and pulling on the slippery length of his thick prick as he wildly fucked in and out of her steaming pussy. His virile young cock-shaft was glistening with the creamy juice that was oozing out from between the goat's squeezing cunt-lips.
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.
