Zack dreamt of taking his sister for a long time. He snuck in her drawer when he was alone to impregnate her underwear with his essence. Christy didn't show any signs of disapproval until one day she catches her brother with his cock inside her favorite pair of panties.
Terror grips Zack. He's been caught and probably branded as the most fucked up weirdo in the whole world. Or is he? His expectations are turned upside down when his sister reveals just how kinky she can be. First, she asks him to masturbate in front of her. Then, she plays with her brother in the bathroom, measuring his cock and stroking him to completion.
And then she takes it even further, when Zack's dreams reach completion in the most unexpected way possible.
How deep is the relationship between these two horny siblings going to get? Read the story and find out!
***STORY TIME***
Watching a movie with Christina was always a challenge. She either shifted every few seconds, or scratched herself of whatever imagined itch her hyperactive mind constructed.
"Can't you stay still for at least a minute?"
"I can, if I want to," the little female smiled.
"And I assume you don't?"
She shook her head so quickly her ears whipped about. "Nuh-uh."
"Not even if I ask nicely?" Zack made the puppy dog eyes. He knew his sister couldn't hold her ground against that kind of stare for long. She pursed her lips and stared at the TV, arms wrapped around her tightly pulled knees.
"Thanks," Zack said, hovering with his arm just above the back of her neck. On one hand he wanted to lay that arm down, pull her close into a hug and watch the movie family-style, yet on the other he knew even a single touch would distract Christy from her focus meditation. It was a funny name that went along well whenever his sisters adopted that concentration look on her face. She looked so funny, and Zack knew he had to distract himself to prevent the upcoming cough from turning into full blown laughing.
"Ahem," he dragged his voice like a gentleman. "The next scene is totally worth it. This guy jack is super close to catching that badass hacker. Lets watch, and see if karate beat guns."
Christy said nothing. She remained still as a statue even as the detective burst through the door. His pistol was kicked right out of his hands by a ninja clad feline. He grunted, side-stepping an upcoming blow. The feline punched his gut, opening up his throat for a decisive strike.
"Boom, baby!" Zack clapped his hands as the detective choked on the ground. "Did you see that? Saw how fast he was? Three strikes and BAM! Fat cop hits the floor like a fucking boulder."
"Whatever," Christy mumbled.
"What? I didn't hear ya," Zack leaned his closer to her mouth, despite the obvious twitching in her lips.
"Nothing? Because I'm pretty sure I heard something. Come on, don't be a shy girl. Feedback is the most honest form of critique, and I'm pretty sure Jack there would like to hear what you have to say about his combat prowess."
Still silence. Zack was about to pull back before two lithe hands wrapped around his head.
"I don't care about fighting!" Christy said as she dragged him down with her weight.
Zack tried to grab onto the sofa, yet his position was hardly stable. He fell onto Christy's lap, where he became the subject of her furious tickling. Her fingers moved like a storm, tickling around and inside his ears, ruffling his mane, and scratching under his jaw.
"Alright, you win," he sighed. Defeat did not become him, even at the small hands of his sister. "Come on, you had enough."
Yet Christy still held him strong, using the entirety of her arms to keep him down. Zack grabbed around her tiny form, obtaining laughter and pelting saliva along with the upcoming wave of tickles.
"Just....leave me to...just....will you just-"
"No. No no no no no!" Christy kept laughing. "You're mine. All mine."
"You sure?" Zack took a deep breath and descended along her back. Christy's weight was all focused forward, so it was no problem for a male of his stature to lift a female of her weight. The little zebra screamed like a sissy as the world spun around her. Zack flipped her over, placing her belly up on his lap.
"Looks like you're mine now."
"No. I'm not!" she frowned stubbornly.
"Wrong thing to say, darling."
Zack tickled her with righteous vengeance until she squirmed and kicked and screamed.
"You'll be good now?"
"I-I will! Please stop!"
"Good," he grabbed the girl and placed her back on the sofa. She threw him an angry glare, then looked at the TV with the same concentrated look.
Zack tried to enjoy the movie along with the silence, but it didn't seem right to keep his sister waiting. He lunged for the remote, grabbed it inside his hand, and handed it to his sister.
"Don't want it," Christy pushed it to the side.
Zack sighed at that. "Come on. You can pick whatever movie you like."
"I don't want any," she repeated. Her hooves touched the wooden floor and she started pacing around the room. "I don't like movies. They're scripted and boring. I don't care if Jack dies, because he will be back in another movie!"
"Well, it is a form of entertainment, darling" Zack waved his remote around. "What do you expect, for actors to do all that crazy stuff in real life?"
"Yes!" Christy crossed her arms, looking straight at him. "Why can't they love each other, like in the romance movies? I loooove to see them cuddling and kissing."
"They do that with their wives, sis."
"I'm too young to marry. I'm too young to do anything!"
"Come on..." Zack waved her closer. She hesitated for a brief moment, but once she released her tension through a sigh, she jumped on his knees, placing her bushy tail right on top of his member. Neither of them were disturbed by the close proximity of their genders after walking around naked for years. Wearing nothing felt liberating, even if most of the society frowned upon such practice. Here at the countryside, there was no one to watch, and in the absence of scrutinizing eyes Zack and Christy could do anything.
"I'll grant you one wish for being a good girl."
"You're lying."
"Try me," Zack kissed the back of her neck. "Tell me one thing you desire, and it will be yours."
"I want to visit Shell's farm!" Christy turned around with big eyes and an even bigger grin. "I want to talk to Maggie, and Sara, and ride their ponies all day! Please, brother, please make that happen!"
Zack found it slightly hard to speak with his ears pulled and his mouth blocked by his sister's furious nuzzling. She pulled back just enough to stare him in the eyes, then planted a wet kiss right between his nostrils.
Tingling warmth surged through his spine. "Alright. It's done."
"So fast?" her eyes widened.
"Yep. I'll take you there myself if I have to."
"Thank you!" she hugged him with the ferocity of a young bear. "Thank you, thank you, thank you!"
Zack patted her back to distract her from the throbs poking between her legs. He was pretty sure she felt that considering her own gender was spread open. Zack winced, and Christy openly gasped when their genders kissed with a warm, wet, tingling touch.
"Well, lets get going then," he pushed Christy off him as he got up. "I want you back before sundown to help me with the tractor."
"I won't stay long. Just for a ride or two around the forest," Christie smiled at him.
It was somewhat relieving that his sister wasn't going through one of her curious phases today. Zack had to work on the tractor since the sun came up. The only break he took was half an hour ago to eat and tend to Christy's morning routine. She usually liked to watch movies as soon as she jumped out of the bed, yet "Gustin's Grant" didn't impress her in the slightest. Too bad, considering how highly that movie was rated.
Zack walked towards the kitchen. His member swished unceremoniously with each step he took. Christie glanced briefly, but she mostly kept her eyes to herself. Privacy was no problem for two long time nudists. Zack was well accustomed to glancing and grabs. Christy knew his cock almost as good as she knew her pussy after the years they spent touching and exploring each other.
"You're excited, brother?"
"Meh. A bit, I guess," Zack scratched the white mane rippling along the back of his striped neck. "Didn't have much time to myself today."
"You'll have enough after you fix me breakfast."
He looked at her as if she switched genders before his eyes. "Come again?"
"I want salad, brother," Christy grabbed his arm, tugging him forward. "You know Shell doesn't cook, and his doggie clan only eats meat. I hate meat!"
"They have grass around their farm, don't they?"
Christy stuck her tongue out and tightened her grip.
"Fine. I'll fix your stuff. Just leave me room to work."
She seated herself at the table, making forms with her fingers and playing with her tail.
Zack grabbed oil, juices and salad from the fridge and procured the spices from the rack above. He washed the salad in the sink, throwing an occasional glance in Christy's direction. Her eyes were focused on her tail. She ran a hand towards the tip, smoothening the hairs while the other picked at the tangled strings. Zack smiled whenever she frowned. She looked incredibly cute when she muttered an angry word through that little muzzle of hers.
Christy was beautiful. Small, yes, but quite nimble and athletic for her age. Zack always admired her. She combined the best qualities from their parents, retaining mother's mirthful attitude and father's determination. The fact that she was beautiful was another thing entirely. Many times Zack got hard when he peeked between her legs. Even if he was familiar with her pussy, seeing it transform from the little slit she had when she was barely a year old to the well toned crevice she now displayed was quite stimulating. Her pink lips were soft and curved beautifully on either side of her hidden passage. Soon, they would swell with the ripe hormones of adolescence and fill the air with a miasma that captured every male's heart and fettered their instincts.
Zack shook his head. He was growing quite hard at that particular though, and he didn't want Christy to think he had a salad fetish or something ridiculous like that. He moved on the side of the sink to cut the salad, then threw it in a bowl where oils bathed it and spices adorned its verdant leaves. Zack stirred the mixture for a bit, then delivered the bowl between Christy's expectant hands.
"Mmmm. Looks delicious."
"Tastes the same. Go on, grab a bite."
"Mmmmm," the little zebra moaned with joy. "It's so good. Want a bite?"
"Nah, I'm good," Zack took a seat and crossed his legs to cover his obvious erection. He grunted a bit at the added pressure, looking through the window to distract himself.
Golden crops rose all around their home. In the distance, he could see patches of forest, along with other farms. On his left, he had the broken tractor, with its many parts spread on the ground. He had to get that damned thing fixed, and soon. If the rains came too soon, all of the harvest could be compromised.
"I'm done!"
Christy's voice distracted him from his musings. With a curt nod, Zack pulled himself up. He grabbed his sister's hand as she led him towards her room. Big and witty as she was, Christy still needed help to get dressed. That's how she called it, at least. What she branded as help was nothing more than another chance to show off.
"Do you think this looks good?" she waved a red blouse around her chest.
Zack clicked his tongue. "Too colorful."
"Isn't that a good thing?'
"Not if you're riding ponies, my dear," he grabbed the vile piece of clothing and placed it back in her wardrobe. "What about this one?"
"Yellow?" Christy scowled.
"It's simple, practical, and goes great with the sky."
"Fine," she snatched the T-shirt. "But I'm picking the pants."
"Have at it. I'll search for some proper underwear while you...erm, prepare yourself."
Zack's heart quickened as he approached the drawer. He knew what hid in there. It became as obvious as his hardening cock. With a hand, he grabbed the drawer, gently sliding it open. A mixture of scents assaulted his nostrils as soon as he did that, sweet and enchanting just like the spices he placed in Christy's salad.
"Picked one?" she said from behind.
"Still searching," Zack said quickly, pretending to shift through things. "You've quite a mess down here."
"I can-"
"No. Just try on your pants and wait."
His heart raced madly as he shifted through the only three pairs available. Verdant green, lavish purple, and pristine white. They all felt rather rough to the touch, courtesy of all the fluids embedded into the fabric.
Flashes of memories passed through Zack's head. Almost without thinking, he grabbed a random pair and sniffed into it with a deep, hungry whiff. The smell of his own essence seeped deep into his nostrils. A soft moan escaped his throat. Zack coughed quickly, blaming that on a bug.
"I...this pair should do," he fluttered a small bra at Christy's skeptical eyes.
She lunged, grabbed the white panties, and put them on in front of Zack's shivering form. His jaws clattered, and he had to keep them tightly pressed to avoid being the creepy sort of brother.
"Can you comb my mane a bit?"
"Naah. You're good, girl," he ruffled her up despite her heavy protests. "You're going riding, and out here, messy means tough!"
"Ok, ok, you can stop now. I'm messy enough as it is."
That word had such improper connotations given the situation. Zack wrapped an arm around her neck, directing his sister through three doors and a porch.
"Jeez, why so hurried?"
"I have to work, and you have a pony to ride."
"And you?" Christy grabbed his firm cock between her petite fingers. "What are you planning on riding?"
Zack's ears throbbed as if molten lava surged through them. "N-nothing. I'll work on the tractor."
"Sure you will," the female trailed her hand all the way to the flare, then rubbed it a bit for good measure. She chuckled at the male's heavy sigh, wiping off the beads of precum on her pants.
"I'll see you later then!"
"Yeah. Have fun!"
Christy grabbed her bike. She pedaled towards one of the forking paths, slowly disappearing between the shifting fields.
Zack knew this was his chance to relieve the burden that has been churning inside his balls since last night. He rushed back to Christy's room in a thunder of hooves and clattering teeth. The door banged shut behind him. Zack dropped on the ground as soon as he had the chance. He crawled towards his sister's set of drawers, pulled open the panties compartment, and pushed the two pairs against his widening nostrils. Her natural scent was latched upon the fabric, soft and gentle compared to the strident smell of aged seed. Zack moaned, fondling the small pieces of cloths between his fingers. He always liked how soft the fabric felt. It had to be like silk, to prevent rubbing and chaffing. Only this time, he was in need of a good rub down there.
Zack trailed the panties down his chin, along the sculpted muscles of his chest. He didn't stop until he reached his cock. Twelve inches of thick throbbing meat greeted his fingers as soon as he touched himself. The male groaned blissfully. It took great restraint to avoid thrusting into his own hand. Many times Zack did that, when he was young and horny, spending himself long before having the chance to properly enjoy himself.
Things changed though. He was bigger now. Stronger. And yet still equally aroused. He followed his black cock all the way to the pink splotched flare widening at the tip, then placed the red pair of panties upon it. He rubbed it around briefly, groaning and moaning before he fit the green one on his head. Stimulated from two sources at once, Zack gave in to the fire blazing within him. He crawled towards the bed and sat on it, fondling his cock through the silky fabric of Christy's underwear.
Christy, with her big, beautiful eyes, her shining tail, and her pink, exposed flesh. She appeared in his mind, naked like a newborn calf. Zack grabbed himself harder. He approached her without any hesitation or restraint. Christy looked at his cock. That's all it took, a single, fugitive glance to get her flesh ready and lubricated. She touched herself down there, and moaned as a long squirt of translucent goo splashed from the depths of her pussy.
Zack's jaws tightened with rising arousal. Christy was milking herself right before his eyes. Endless spurts splashed from her lips, making a whole mess inside the panties she suddenly wore.
He blinked. Fantasies always flickered unless he concentrated hard upon them. No matter how much he focused, Zack couldn't bring up the same scenario inside his mind. A shame, considering how drenched Christy's panties were.
"Fuckkkk," he moaned as he pushed a finger right against the tip of his cock. The sharp stimulation made him stiffen instantly. Zack's hooves crossed one another as his knees pulled up. A long, heated surge traversed his cock, expelled in rivulets of precum. The fluid seeped into the panties too quickly, drenching them whole before escaping onto the ground below.
Zack scrunched his eyes and muffled his groans of delight. His balls felt so tense, and his crotch tingled with seething agony. He wanted to cum so hard right now. Wanted to push out all the lust churning inside his crotch.
Yet the thought of his sister refused to leave his mind, haunting him with heated flashes of perfect fantasies. Christy appeared yet again before his eyes. She begged him to come closer, and help put on her first pair of underwear.
Zack crawled towards her, feeling unreasonably weak. The scenario changed just as he was about to reach her. Christy was in a school or something. She sat in front of the class, head bowed, tears falling down her eyes. A mean canine chastised her in front of the students that mocked and ridiculed her nakedness. She had nothing on her, apart from a pink pair of panties that seemed far too stretched and much too heavy.
Christy pulled them down, revealing the immense load burdening their insides. A pool of fresh cum was sheltered inside. The fluid latched onto her pussy, forming bridges that snapped the more she pushed.
Zack stroke himself furiously. He was getting closer to his release. His raging seed pressed hard against his crotch, almost ready to be unleashed.
The door suddenly burst open. Zack gasped. His eyes suddenly snapped open. He felt shaken, and horribly aroused, yet even in this cloudy state he could make the shape of his intruder. It had a yellow shirt, blue jeans, and thick black stripes mating with the white shapes of her short fur.
"Christy!" he said, almost choking upon the sudden revelation. His hands instantly rushed around his cock, trying fruitlessly to cover up the whole, throbbing length.
The female giggled, eyes sparkling with a mischievous smile. "You don't have to hide it from me, brother. I see it every day."
"You're freaking kidding me," Zack pushed himself on his belly to shelter his thick meat under layers of fur and muscle.
"No, I'm being honest."
"D-don't approach," he waved a hand back, cheeks burning with embarrassment. "It's weird enough you found me like this. Why the fuck are you here anyway?"
"Shell had an unannounced family reunion," the bed creaked slightly as Christy settled her bum on the corner. "Told me I can stay, but it became weird seeing so many strangers around."
"Bloody fortunate. Gaaaahhhh, this is annoying."
"Why?"
Her touch made Zack's tail lash around furiously.
"OW!" Christy yelped.
"Not my fault."
"It is! You just slapped me."
"Because you touched."
"Since when I'm forbidden to touch my own brother?"
"Since now!" Zack turned his head around to look her in the eyes. She was hurt, and surprised, looking at him with those big emerald eyes.
Zack's temper cooled off somewhat. "You just caught me in a very bad moment, sis."
"It's not that bad," she dropped onto the bed to crawl closer to him. "I've known this for a while."
"Knew what?" Zack asked, despite knowing what answer to expect.
"Everything. I'm not a stupid cub anymore," she took the pair of panties from his head and rubbed them between her fingers.
"Technically, you are."
"Fuck you," she slapped the panties between his eyes, forcing Zack's eyes shut. "I played along only because you're stupid like this. Knew that if I told you, you would overreact like mom and dad do."
"I..." Zack shook his head. "I'm sorry. I didn't meant to hurt you, sis. I get bloody stupid sometimes. It's a male thing, I guess."
Christy pushed her head under his neck. Zack was pleased to hold her close to him until Christy revealed her darker intentions. Her hand sneaked under his belly. She grabbed the male's flare inside her cupped palm and twisted hard, releasing a long, trembling moan from his throat.
"Aaaaahh...."
"Does it feel good?" she whispered, rubbing that soaked pair of panties around the sensitive flare.
"Y-yes. It feels so fucking good," Zack nodded eagerly. He was tempted to just shoo her away, but his sister deserved a bit of lenience after his little outburst. She kept rubbing for a bit, making remarks about how sticky he was before her hand retreated.
"I'll let you finish what you started, but on one condition. I get to watch."
That bargain was no bargain at all. Zack rolled on his back, presenting the entirety of his cock to Christy's watchful eyes. Her mouth refused to close as he stroke his length, spreading the slick precum along the glistening skin.
"You're huge! I mean...everything is so big..."
"Wanna touch?" Zack pushed his hands on the bed to allow her room to maneuver.
Christy shook her head. "Maybe another time. I never saw you cum before." A wide smile spread across her face. "Show me. I want to see you cum!"
"Alright. Jeez. No need to be so insistent," the male slowly pushed the underwear away from his tip. Christy lurched forward, slamming the accessory back onto his tip.
"You want me to cum inside this?"
She nodded and licked her lips in quite the devious way.
"Alright. Here goes nothing."
It took a bit to bring his lust to the previous levels, but with Christy watching it didn't take long at all for the male to bring himself on the edge of orgasm. His eyes scanned every last one of her features, from her perky ears to the tail swishing behind her. He pleaded with her to strip, and was most pleased when Christy got rid of her clothes. She threw her shirt on the bed, then slowly worked on her jeans. Zack grabbed himself harder, stroking furiously around the tip.
Christy pulled her pants down. Little by little, she revealed more of her striped fur. Zack's heart beat with maddened frenzy. He knew what was coming. Felt it as strong as he throbbed. The azure pants suddenly fell, revealing his sister's perfectly shaped sex. Smooth walls, straight slit, and below, a piece of underwear that still carried the fragrance of his seed.
The sight of it did it for Zack. He squeezed his eyes shut and threw his head back as unbridled pleasure rushed through his spine.
"Are you...?"
"I'm cumming!" He shouted a lot harder than he intended, and grabbed himself just the same.
His rock hard cock flared, unleashing a mighty spurt of sticky cum. Zack thrust hard into the underwear, splashing his seed all around the thin fabric. His hand pumped around his cock, forcing it to throb even harder. Zack moaned blissfully and grabbed onto his balls with his free hand. The spheres clenched under the grip. He pressed and massaged them with swift jerks, adding unrelenting waves of stimulation to his clenching crotch.
Zack thrust, and pushed, and emptied himself into the panties he furiously rubbed himself with the pair. They were a sticky mess, dribbling with more seed than they could carry. Pearlescent rivulets gathered in thick globs that splashed onto the ground right before Christy's wide eyes.
"It's not stopping!"
"Haaah, it feels so good," Zack shuddered, pulling his knees above his rock hard cock. The switch in positions added more pressure under his balls, causing his semen to splash in short arcs. The panties caught it all for a brief moment. Zack never kept them still. He rubbed them around his head, satisfying himself until the raging torrent was reduced to feeble trickles.
"I'm...I think I'm done," he finally took a breath of fresh air.
"Good," Christy snatched the panties from his trembling grip. She worked her pair down, then climbed into this sticky one. The underwear slapped with a lewd squelch as it connected with her bare pussy.
Zack gritted his teeth, cumming a bit more at such arousing sight. "How do they fit?"
"Perfectly," she jumped onto his chest without any regard for his receding erection. "They're warm, and wet, and so soft."
"Glad...glad you like them," Zack said, still breathless from the intense ejaculation. With Christy's soiled groin pressed against his balls, he almost wanted to give it another go.
"How did you find out?" he asked instead as he fondled his sister's mane.
"Wasn't hard to. One day, when I went to get dressed, there was this funny smelling thing on my panties. I checked my pussy, thinking it came from me, but it smelled different. Tasted different."
"You tasted them?" Zack asked.
"Yaaah. It was weird, you know? Finding your underwear wet like that. But I had nothing else to wear so I put them on."
"How did it feel, when you first...?"
"Surprisingly good," Christy said. "Took a bit of time to adjust to the smell though. The other kids thought I'm dirty, but I knew better than them!"
Zack looked at the ceiling, too embarrassed to match his sister's gaze. She might have been smaller than him, but she wasn't any less smarter.
"Did the teacher find out?"
"No. I blamed my bike for the smell, and everybody bought it."
"Jeez, Christy. You could have been caught, or punished. What the fuck was I thinking?"
She kissed his sweetly, rubbing around his ears. "It's fine. Stop worrying. Besides, it was my choice to wear them. They make me feel good, brother. All the other kids wear the same boring stuff, where I can bring a part of you with me wherever I go!"
That analogy was a bit disturbing, but Zack went along with it. He hugged his sister, pressing her tight against his muscular body. "Oh, Christy. You are as odd as your crazy brother."
"I'd rather be crazy than normal."
They both laughed at that. Zack cleaned himself on the sheets at Christy's request and went out to fix the tractor. Having a helper was invaluable to his cause when he crawled under that metal beast. Christy handed him the wrenches so he could properly focus on dismantling the amalgamation of rusted metal, bolts, and whatnot.
"So, how's school coming along?" he extended his hand to grab a metal splicer.
"I got vacation a month ago."
"Yeah, old topic. So what? I'm pretty sure you are still keeping stuff from me."
"What sort of stuff?"
Zack caught the hint in her voice. "You're freaking amazing at copying, did you know that?"
"Learned from the best," she laughed. "So, what do you want to know?"
"Eh, nothing much," Zack unscrewed a couple of bolts and cut around a rusty pipe. "Just...you know. If you have any male friends and stuff."
Christy was silent for a bit. She handed him the miniature blowtorch and the gauntlets to protect himself from the heat. Zack cauterized the wounds, rolling onto her side.
"Are you going to answer that question?"
She shrugged. "There's no answer to give. I've got no one worth mentioning."
"But you got someone?" he winked at her.
Christy crossed her arms stubbornly. They held stares, scrunched and frowned at each other until she finally relented. "Fine. I got no friends. Is that what you wanted to hear? That I don't care about anyone except you?"
The last remark threw Zack a bit off. He knew siblings shared a certain bond, yet Christy was always quite reserved with her feelings. To openly declare her fondness like that meant that she cared. And when she cared about something, she moved heaven and earth to get it.
"I love you too, Christy, but..."
"Don't," she threw herself in his dirty arms. "Right now, I want just you."
He held her warm body in his arms for a couple of minutes before he went back to work. Things weren't the same after that. His stubborn mind latched itself onto Christy. He kept thinking of her in certain situations; situations that had her completely exposed to his whims. Zack took her at least five times before the sun lost its bite.
"Alright, it's enough for today. Lets go inside and wash ourselves up."
"I wanna take a bath," Christy scratched her grime covered hands.
"Perfect idea. You go first then," Zack turned towards his room.
A hand grabbed him.
"No. I want you to be there with me."
His heart almost leaped in his throat. Zack nodded and quickly followed his sister inside the bathroom. It was quite small, but with a cozy feeling to it. Christy turned on the hot water and smiled as the steam rose all around them.
Zack shifted on his feet. Her naked body tickled his fur, especially around his groin. He scratched himself and tried to act normal, yet his member had a mind of its own. It tensed under a rush of heat, making Christy smile all the brighter.
"Yeah, it's so funny. Lets all watch the big brother get hard while his sister watches like a..."
"A what?" she taunted.
"A little, sneaky pervert!" Zack ruffled her head. "That's what you are. I know your plans, and why you brought me here?'
"You...do?" she asked hesitantly.
Her change in attitude was somewhat weird. Perhaps merely watching wasn't her intention, but there was only one way to find out.
"You couldn't peek under other males' pants, so you want to see how a stiff cock looks like. Am I right?"
"Close," she moved a hand towards his cock.
Zack grabbed it mid-air. "Don't. You're here to watch, not to touch."
"But it's fuuuun."
"Shush. I'm the male here, not you."
She scrunched her features and crossed her arms. Zack knew she wouldn't remain mad for long. Not with such an interesting view posted before her. With his arms curled behind his back, Zack straightened himself to allow full view of his rising cock. The throbs made it longer, and each jerks pushed it higher.
"It's funny, how it bobs up and down. You're doing that, right?"
"Nope," Zack revealed both of his hands. "I'm not touching it."
"But you can make it jump. Look!" she touched his flare, causing his whole cock to stiffen and jerk.
"Ngh...it's...difficult to explain, sis. I can control my cock a bit, but I cannot harden on my own. Arousal does that, just as rubbing makes me cum."
"You ever came without touching yourself?"
"A few times, in my sleep."
"That happened to me too!" Christy said excitedly. "There was this one night where I fell asleep, and dreamed of having your cock inside me. Strange, right?" she pulled onto Zack's hand. "I didn't even know how your cock looks like and in my dream, you put it inside me. It felt sooo strange when I woke up. There was sticky everywhere. I must have peed myself or something."
Zack licked his lips. "It wasn't peeing, Christy. You came."
Her eyes widened at the realization. "I did? How?"
"It's called nocturnal emission or something like that. Basically, our bodies get all pumped up if we do not pleasure ourselves, and release all that strain during the night, in the form of these emissions."
"That is so weird," Christy scratched under her neck. "Can I show you this new technique I've learned? It works very well. Makes me cum in less than a minute!"
Zack was surprised how forthcoming she was about it. "Wait. You came before?"
"Pfff. Say that like you haven't played with yourself when you were my age."
"I did, but...you didn't tell me about it."
"Why tell when I can show you?" Christy winked and settled on the bathtub's edge. Her lips parted open to reveal a wet, fleshy tunnel. It was looser than Zack expected, and dripping wet.
Christy inserted two fingers inside, swirling them clockwise. She moaned softly. Her legs crossed, pressing her folds tighter against her fingers.
"Just...look," her words barely broke through her tightened jaws.
Zack crouched to notice there was a reason for all that swirling movement. A small nub of flesh hid inside the depths of her cunt. Christy circled it, harder and faster, until her walls suddenly spasmed. A splash of clear liquid broke loose. She groaned and moaned, shivering uncontrollably as her orgasm rolled in. Zack quickly grabbed her in his arms to prevent her from falling. Christy mewled like a newborn cub, pushing the heat out of her in four quick squirts.
"You silly sister. Look at all the mess you made!"
"Haah..fuck you, brother," she slammed her little hands against his muscled chest. "
"Wanna fight?"
"Yes. Lets see who cums faster."
"Hah, easy," Zack said with a smug grin.
"Not if I'm touching you," Christy grabbed him by the flare, forcing his smile to turn into a weak moan of pure bliss. "I work on your cock, and you work on my cunt. Those are the rules."
"Christy..."
She rubbed a finger around his opening. Zack threw his head back and groaned, shivering from every joint of his body.
"Are you in, or are you out?"
"In...in! Just...fucking release my cock, damn you."
She didn't listen, rubbing his flare hard inside her cupped palm. Zack bit back the intense pleasure and plunged two fingers inside her cunt. Christy flinched, but other than that she showed no signs of debilitating weakness. Her hand rubbed viciously, scratching and poking at the soft ridges decorating the edges of the stallion's flare.
Her pussy squelched when she squeezed. God, she was so wet, and so tight. Zack's fingers disappeared halfway into those soft, drenched folds. Christy moaned softly, allowing her breath to rush out in a melodic groan.
"Getting close yet, sis?"
"Not as close as you," she said, slamming her other hand into his balls.
Zack's tail lashed to the side. He knew his sister was a sneaky bastard, but he didn't expect her to outright cheat. Her fingers moved deftly around his hard sack, stimulating the spheres hiding underneath. Having such a sensitive part of himself cupped in his sister's palms made his cock throb all the harder. Zack hissed, squirting a gush of precum straight into her grip. Christy chuckled. She smeared the lubrication all over, turning her pumping palm into a veritable semblance of a cunt.
"Ghaaah."
"You're gonna cum."
"Not...yet," Zack hissed.
"You want to, brother. Let your seed loose. Pour yourself inside me."
Inside...she used that word purposefully, didn't she? Because his blood seethed hotter and pumped a lot faster at the thought of plunging his whole erection into Christy's hungry folds. Zack wriggled furiously, yet he didn't have as much time as he wanted to practice on female anatomy. He tried hard to find the nub of flesh she stimulated before, but her clamping cunt made that task unreasonably hard. Zack ended up thrusting in and out, hoping a rough pounding will do the trick.
It didn't. Christy moaned and shivered, but she didn't cum. Her smallest finger rubbed around his cock hole, playing in the slimy precum before inserting itself through the oversensitive passage.
Zack froze as a jolt of numbing pleasure made him tense all over. His cock jerked up, becoming hard as the marble beneath his hooves.
"You're gonna cum."
"Naaaah..." he splattered her fluids all over her shivering folds
"Cum. Cum. Cum. Cum!"
Zack gritted his teeth and held onto his breath. It was coming, too strong, and too fast.
"Cum, brother. Cum!"
"Fuuuuuck!" Zack howled as his hips involuntarily thrust into Christy's hardening grip. She fettered and pumped into his widening flare, bringing him way over the edge. His cock jolted once, unleashing a thick rope straight into her rubbing palms. Christy gasped. Seed flew all around them, pelting and splashing the ground, the tub, and their striped fur. Christy especially became the target of the assault. The sheer pressure of the ejaculation pushed her hand away, ramming two jets of thick seed into her neck and chest.
"Nghhhhh!" Zack forced his eyes to stay open to see Christy's dripping form. Eyes closed, mouth open with wide admiration, she took the jets of seed straight onto her lithe little body.
"Too much!" She squeaked, and Zack didn't stop. He pushed his erection between her breasts, flooding her body with milky strands of dripping cum.
Christy grabbed her underwear from the clothes basket and covered his flare with it. The feeling of the familiar material pushed Zack's pleasure even higher. He grabbed his cock like an animal and pushed into the elastic panties, pounding them until the last squirt of cum left his enraged cock.
"God, you made a real mess," Christy said as she flung off the sticky cum.
"Get...get in the tub. I'll clean it up."
"You betcha!"
Zack propped himself against a wall to calm his rapid breath. He never came so hard before. Being touched by another was just something else. He pulled the dripping panties from his cock and put them on the rim of the clothes basket. Then, he watched Christy as she took her bath. She fingered herself again in the hot water, and orgasmed before his very eyes. Zack thought he had seen it all until she strapped on the cum flooded pair right after she dried herself. He looked at her with a mixture of shock and amazement. Christy smiled. The hug she gave him that day was one of the most memorable Zack ever received.
The next few days passed in a rush. Zack was too distracted with his tractor to care about taking care of himself, and Christy was more than happy to help. After three days of hard work, the two siblings cuddled in front of the TV. Christy's favorite movie aired tonight, yet she didn't seem as interested in the talking raccoons as she was in her own, young pussy. She lied a couple of times about an itch she got from the sweat and the dust, but Zack knew a lot better. His sister was fingering herself right through the panties.
"Christy, you're missing the show."
"Whut?" she looked back with her big verdant eyes.
"The show," Zack pointed at the TV. "You're missing it. Wasn't Rocky Raccoon your favorite?"
"Huh, maybe," she blinked and turned back to the TV. Not even a second later her hand slithered between her legs.
Zack jumped off the couch and rolled on the ground to came face to face with Christy's crotch. She smiled, then gasped when his hands pulled hers away to expose her crotch. The white pair of panties was splotched all over by her ongoing arousal. Zack touched her. Christy flinched, attempting to crawl back.
"No," he grabbed her from behind. "Stay here, Christy. I'm gonna take care of you."
"R-really?" she whimpered with longing and desire.
"Yeah. That's what siblings are for, right?"
She gave a stiff nod, then stopped Zack when he reached towards the rim of her underwear. "Through the panties. Please..."
Zack smiled widely. He fondled her sex gently, feeling the edges of her lips. She was dripping down there. Poor Christy must have been aroused for hours to expel that much lubrication into her underwear. Zack slowly pushed between her lips. She winced.
"Dee...deeper."
He sunk past the entrance of her folds, immersing himself between her silky walls. Zack rubbed around. The texture of the panties grabbed onto her flesh. He knew that must have felt good, for Christy started panting like a fatigued beast. He pushed deeper, and deeper, until he found that elusive nub of flesh. He cupped it between his large fingers and rubbed, watching Christy's reaction. Her tail stiffened behind her, and her legs crossed. She rubbed her eyes with a quick swipe and sniffled between her quickened breaths.
"Feels so good..."
"I know," Zack rubbed quicker.
"Ahhh..." she yipped. "I'm gonna cum, brother."
"Feel free," Zack filled her harder and faster. "Cum all you want, dear sis."
"I'm gonna cum! Gonna-"
She yelped when her climax hit her. Zack's fingers were flooded by squirts of liquid heat. He continued rubbing his sister, prying her walls apart and scratching around her most sensitive of places until she reached completion. When her orgasm ended, her panties were thoroughly flooded with her juices.
"How was it?" Zack asked, trying hard not to give in to the permeating smell of arousal. He hadn't ejaculated for days, and his instincts fought hard to usurp his concentration.
"Good. So good," Christy shuffled back.
He thought she was going to take a small break, but he couldn't be more wrong. Christy grabbed her panties and slowly pushed them down, revealing the slick, pink lips of her pussy.
"Fuck me, brother," her sweet voice came, broken by lust and longing.
"Wh-what?" Zack blinked.
"Mate me," Christy repeated. "I'm tired of all the fantasies and the dreams."
"What are you saying, Christy?"
"I love you!" She screamed. "That's why I don't have friends! I want you, and only you to care for me, and hold me, and...mate me."
"Christy..."
"Please," she begged with teary eyes. "You don't know how many times I imagined that big cock of yours sliding inside me. I need this, brother. I want you inside me."
Zack shook his head, having problems comprehending her request. His head practically swam in arousal. He wanted to fuck her so hard right now, but Christy was her sister. He just couldn't pound her like any common whore, could he?
Her petite hand grabbed around his fingers. "You already touched me, down there. Your seed has been kissing my lips every time I put on my panties. How is this any different?"
"It's...we're siblings, Christy."
"Siblings should love each other very much. You told me that, Zack," she slowly crawled back and spread her legs, offering an irresistible view of her drenched walls. A deep, looming hole. Soft muscles to caress his cock.
And more lubrication than any male could handle.
"Fuck me. I want this."
"Haaah, alright," Zack groaned. "But only this time, to see how it feels. I don't want your first time to be with a jerk who only sees you as a cum dump."
Christy lay on her back, completely exposed. Zack moved above her. He rubbed her sides and kissed her sweetly as he rubbed his flare around her lips to get her used to the feeling. Christy moaned. She grazed on his chin, whispering softly. "Fuck me, brother."
Zack couldn't delay any longer. He wanted to claim his sister, right here and now. He gently pushed himself forward, allowing his flare to press against her folds. They groped and massaged around it for a bit before a soft thrust sent his cock into their embrace.
Christy whimpered, wrapping her arms around Zack's neck. "Ohhhh...so good. You're...so big."
"I'll go gently on you, sis."
"Please. I want to cum, brother. I want to cum so much..." she mewled, fondling his ears and licking his chin.
Zack propped his muscular arms on the couch and gently pushed himself into his sister. Despite her frail age, she fit wonderfully around his cock. Her silky walls parted as he advanced, only to tighten a moment after. Those gropes made Zack stiffen hard. He didn't know how long he was going to last inside when he hadn't spilled his seed for days.
Christy's pleas helped him going. He slowly pulled back when she winced, allowing her a breath of relief. When she nodded, he thrust back in, advancing a bit further than before. Christy moaned as her walls were spread open by her brother's long cock. Zack's flare scratched her flesh in all the right places, making her moan louder and shiver harder. When he touched her nub of flesh, Christy yowled, allowing her second orgasm to roll over.
Zack braced against the flood. Rivers of hot female cum rushed around his cock to spurt out on the black leather sofa. The sensation felt so intense. He curled his fingers and thrust deeper, filling his sister with two jets of precum.
"So good. So good," Christy moaned, shifting restlessly until her orgasm ended.
They both panted like wild animals after a hunt. Zack was still inside, fighting back his urge to cum. His balls felt so heavy, and his tailhole pumped wildly against his prostate.
"I think I'm gonna cum," he grazed into Christy's neck. "Are you ready, sis?"
"No," she pulled herself back. Zack thought she was going to pull herself out, but she merely got onto her fours, twisting herself around his cock. Both zebras groaned and moaned at the blissful sensation.
"What did you do that for?" Zack asked, laying on his back to look upon her dripping cunt.
"I want you to take me from behind, like the dogs to in the movies."
"Really?" he asked, wide-eyed.
"Please...they yowl so hard. It must feel good, right? The male always thrusts so hard and fast. I want you to do the same, brother," Christy smiled meekly. "Fuck me, like a dog takes a bitch."
Zack was not about to disagree with her request, especially not when he was still inside her. He got onto his knees, arms wrapped around her torso. When Christy voiced her consent, he pulled back.
Then, he thrust. She shivered with pleasure. Zack mated her slow at first, quickening his thrusts in rhythm with her moans. They picked up, turning into yelps of delight as she approached her climax.
Zack wasn't far from his own either. Muscles bulged all over his body. His arms became iron beams, holding steadfast onto her rocking body. With quick, sharp thrusts, he pushed in and out of her cunt, summoning those wet, delightful noises. Dribbles of clear liquid fell from her cunt whenever he pulled his glistening cock out of her restless walls.
"Gah, I'm close," Zack said, picking up his pace.
"So warm..." Christy hissed between clenched breaths.
"I'm gonna cum," the male repeated, sinking deeper. "I'm gonna cum."
"Nhaaaaaaaah!" Christy yowled her bliss.
Her orgasm sealed his fate. The hot rush of her fluids obliterated any resistance Zack mounted against the blissful pressure rising from within. He pushed himself all the way in, slamming his balls against his sister's wet snatch. Her flesh became abnormally tight, only to widen in a spacious chamber once his flare pushed through a thick layer of muscles.
Christy howled as his cum burst forth. She tightened hard and fast, trapping Zack within. He groaned with bestial wrath, dropping on her back as weakness overcame his body. Thick gushes of seed rushed out of his throbbing cock to splash into his sister's warm, caressing womb. He couldn't believe he went this deep. The revelation struck him like a lightning bolt, quickening his heightened arousal. Days worth of cum spilled themselves out as her muscles milked the life out of him. No matter how hard he tried, Zack couldn't pull back, so he just remained inside her. His tailhole clenched furiously, and his balls tightened, filling her with everything they had.
Christy's muscles relaxed once her orgasm ended. Zack slowly pulled himself back. He slid quickly, aided by the copious amounts of cum he unleashed. A torrent of milky seed washed out of her cunt when his cock came out. Christy clamped down hard, failing to hold in the thick gushes of fertile seed. They splattered on the couch in a long stream before the flood ended.
"You came ridiculously hard," she laughed, swiping a hand through the pool of seed.
"I had a lot in me, sis."
"Good, because I want to mate again as soon as you recover."
Zack didn't know what to say. Thankfully, he didn't have to. Christy wrestled him down, hugging him right in the pool of his own making. Zack closed his eyes, basking in the afterglow. He had to change his record. Cumming inside his sister was definitely a lot more filling than staining her underwear. He wanted to do that again, and soon. Mate her, then sleep inside her for a whole night.
Now that was a fantasy worth leaving, and with Christy's messy hand rubbing the warm seed around his cock, he knew that fantasy would turn into reality sooner than they both expected.
