The last rays of sunlight were already fading when the street lights were turned on. People who enjoyed the nightlife or who dwelled in it were slowly beginning to populate the urban landscape.

Among the nocturnal fauna was a group of teenagers gathered at a cafe table. The young people had gathered from a small party that was organized at their high school but turned out to be a disaster, leading the group of new acquaintances to look for a different option as far away from the school building as possible.

As they sipped sugary coffee, accompanied with different slices of cake, the group split into three pairs so they could chat more intimately.

“I think I've seen you a couple of times in the halls of the school... Where do you live?” asked a young vulpine girl.

“I live across the street from the Blue Whale car wash. Do you?” replied a young male, also a vulpine.

“Wow, I live two blocks from there, we're almost neighbors!” exclaimed the girl, smiling.

The two teenagers were very similar, the features of their faces, their fur with the same shade, even the particular style of their eyebrows was identical. They really looked like two drops of water, an exact reflection but of different sexes, face to face.

“You look great in that dress...” muttered the male, averting his gaze from the girl.

“Thanks, I bought it for the party!” replied the female.

“Sorry... what a disaster,” said the fox, remembering how bad that party at school had been.

“Whew...don't even remind me. I'm glad we left,” the girl added.

“I'm just sorry I didn't stick around to watch Professor McCowen dance,” the young male chuckled.

“The math teacher?” asked the girl, building in her head the image of an elderly feline who was nearing retirement.

“Yes! I'm sure in her youth she was a Hip-hop dancer,” the boy added.

“I knew the party was going to be terrible... But I heard that Professor Shakur would be attending,” the female admitted.

“Professor Shakur? I don't understand what all the girls see so much in that guy,” growled the young male.

“He has a nice body, a deep tone of voice, his hands always look firm when he grips the edges of his desk and... he always wears tight pants, very tight... too tight for what he carries between his legs,” the girl explained, as she imagined herself in the hands of her teacher, remembering every detail.

“I have a big dick too,” reproached the young fox.

Hearing this, the girl almost spit out her latte macchiato but in the end managed to restrain herself and swallow before letting out a laugh. When she recovered, the female said, “It's not all about size!”

“Ooh right, now you're going to tell me you'd be after Professor Shakur even if he had a micropenis,” the boy refuted.

“Of course I would! That beard looks great on him... Besides, I assure you he doesn't have a micropenis,” assured the young female.

“Plus he walks funny...” added the boy.

“He doesn't walk funny, dope, it's an aftermath of the war. I think it gives him a very masculine presence,” replied the girl.

“So... You like only older guys?” asked the vulpine, in a defeated tone.

“I'm kind of picky, but no, I don't just like big guys... I like all canines in general,” admitted the young vixen, winking at the boy she was sharing the table with.

“Ooh...” said the male, smiling knowing he wasn't out of the game yet.

“Do you know where I could find a handsome canine to have fun with tonight?” the girl asked, bringing one of her hands up to caress the boy's leg.

“Y-Yes, I... My parents aren't home tonight,” the young fox hastened to reply.

“So what are we waiting for?” the girl continued, rising from her chair and dropping a few bills to pay for her coffee.

The young male simply nodded and stood up, hurrying to keep up with her until he caught up with the female, who had already started walking in the direction of his house.

The other teens clapped and whistled when they saw the female bring her hand to the male's butt, squeezing his buttocks as they walked away from the group.

“By the way, my name is Serena,” the young female said, as she walked alongside her new friend.

“A pleasure... I'm Benjamin,” the boy replied, moving his gaze between the vulpine's face and her breasts.

The walk lasted only a few minutes, as the excitement of the teenagers made them reach their destination in record time for the young fox. When they stopped in front of the door of the house, Benjamin rummaged through his pockets until he found the key, his hands were shaking and it took him a moment to manage to open the lock.

As soon as both teens entered the fox's house, Serena brought her hands to her new friend's crotch, caressing his sheath, which already felt firm, and his genitals, which emanate a delicious warmth through the thin fabric of Benjamin's pants.

The young male let out a moan as he felt the touch of the female's delicate hands. A quick turn of the key allowed the fox to disregard the rest of the world to focus on the juicy booty that luck had bestowed upon him tonight, encouraging himself to bring his hands to Serena's ass as he sniffed and kissed her neck.

“You can touch whatever you want, no need to hold back,” the female said, with a giggle as she reached for the zipper of the pants that stood between her hormonal need and the piece of vulpine flesh that was already moistening the fabric in which it was hidden.

Benjamin gave Serena's soft ass one last squeeze, snorted a hot breath of air from inside him feeling like a steam engine, and brought both hands to his pants, first bumping into the girl's desperate hands and then reaching for a button that held the zipper fastened and then pulling down his zipper.

When the jeans zipper was loosened, the young fox's penis was released, with his sheath already flared and half of his bone outside of it, slowly dripping drops of precum. After another gentle movement, Benjamin also released his balls, for fear of crushing them with any sudden movement as the two teens frolicked.
 
Serena gripped the boy's penis with both hands, lightly moistening his fur with that crystalline natural lubricant while, with her head lying on the male's chest, she sniffed at the pleasant odor produced by Benjamin's genitals.

The young fox tried to relax, enjoying the sensation of being touched by someone else's hands, then resting his muzzle on the female's hair, reveling in the delicate coconut scent emanating from Serena's head.

“Do you want me to suck you off?” the girl asked, after a giggle.

“Y-Yes, please,” sighed the teenage male, leaning his head back until he bumped the back of his neck against the door.

The female straightened up and brought her fingers to her mouth to suck on them before telling the boy, “But let's go to your room. I'm horny but not horny enough to do it in a stranger's living room.”

Benjamin swallowed saliva as he watched the girl taste his precum, dimly understanding what Serena was telling him. When the female repeated again what she had just said, this time with a heavier tone, the young fox awoke from his reverie, grabbed the girl by the wrist and quickly led her to his room.

The teenage vulpine's room was simple in terms of furniture: a closet, a desk with a computer, a bedside table and a standing mirror. What did abound in the small male cave were small attachments: posters of rock bands and video games, some action figures from unfinished collections, stickers from some animated series stuck everywhere, even on the mirror, some socks on the floor, boxes with old objects, and a few more things Serena didn't manage to identify when the boy turned on the light.

“It's... lovely...” murmured the female, as she admired the chaos in the room.

“What is it?” asked Benjamin.

“No, nothing...” replied Serena.

The teen was quick to drop his pants, sit on his bed and spread his legs, waiting for his guest to comply.

Serena knelt in front of the male, gave him a lick from base to tip while caressing his balls with one hand, her tongue soaked with several drops of precum before she kept it back in her mouth to swallow that delicious crystalline gift. After enjoying several samples of the natural male lubricant, the girl closed her eyes, took half of the penis into her mouth and began to suck it vigorously.

Benjamin squinted his eyes, rested both hands on his bed and leaned his head back slightly as he sighed at the first time in his life feeling another person's tongue on his manhood. Despite being in some sort of trance, the teenager felt hypersensitive, the wetness, temperature difference and softness of that tongue running over him from the base where his knot was already forming to his glans from which precum kept dripping and was immediately swallowed by the female.

“Ooh... ooh... “ moaned the teen, rapidly approaching his climax.

Serena continued to suck, lick and deep throat for a few brief seconds to surprise the male. Until, as she sucked quietly, a hearty, warm liquid rushed into her mouth, encouraging her to swallow her long-awaited prize that advanced smoothly down her throat, leaving a spicy taste on her tongue and a smooth sensation in her gullet.

“Fuck!” exclaimed Benjamin, relaxing his legs and shoulders.

When the girl withdrew her muzzle from the foxy penis, she opened her eyes, meeting the delicious image of the teen's manhood, already flaccid though still maintaining its size. From the erotic view she was having, the female noticed a detail she hadn't realized before: a spot on the fox's fur, on the lower left side of his belly.

“What's that?” asked Serena, pointing to the stain.

The boy opened his eyes to see what it was. “Oh! It's a birthmark, my older brother has it too... A gift from my father, I guess,” he replied.

“Fuck me, I have one just like it!” the girl said, standing up and lifting her dress with both hands to reveal her abdomen, which had a birthmark identical to Benjamin's.

“Wow...” muttered the boy, bringing his face close to the female's body to see her fur precisely.

“Wait a minute... Do you have a picture of your father handy?” asked Serena, with a growing suspicion as to what was going on.

“Hmm... Yeah, sure,” Benjamin said, pulling his cell phone out of his pants pocket and then taking a moment to look for a current photo.

The boy found what he was looking for and showed the screen to his guest, who stared intently at the image in front of her.

“I know him! It's the plumber!” shouted Serena, deeply shocked.

“Y-Yes... he's a plumber,” confirmed the young fox.

“No... you don't understand, your father has been visiting my house since I was a child. At first it seemed normal to me but for a couple of years now I've suspected that my mother is having an affair with him,” the girl explained.

“But... So that means... oh fuck!” screamed Benjamin, immediately covering his crotch.

“Hey... easy... maybe it's just a hasty conclusion,” said Serena, seeing the other vulpine in shock.

“But if what you say is true, coupled with that fucking birthmark, it means we're siblings!” exclaimed the young fox.

At that instant, Serena knelt down again and took the boy's face in her hands, forcing them to look into each other's eyes, slowly soothing him, until she brought her muzzle close to Benjamin's and they began to kiss.

The young fox closed his eyes and, feeling the female's warm tongue, let the panic slip away to give way to lust again.

Serena ended the kiss with a lick on the male's muzzle and said in his ear, “Besides, I'm really turned on by the thought of being fucked by my brother.”

Benjamin swallowed saliva and blushed as he watched the teen take her right hand under her dress and make a thrusting motion at the level of her vagina.

“B-but... “ groaned the teenager.

“But it sure would feel great to have brother juice dripping between my legs,” The girl hastened to interrupt, digging her fingers especially deep as she said these words.

“Y-Yes... “ Benjamin stammered, encouraging himself to bring his hands up to the female's breasts, squeezing them gently.

Serena smiled at the feel of her brother's trembling hands. At that instant, she removed her dress, unfastened her bra, and pulled down her panties, offering a privileged view of her entire body to the young male.

The teenager stared at the girl with eyes as big as dishes, breathing heavily, feeling his penis slowly swell back to its full size again.

“First time you've seen a girl naked, little brother?” said Serena, teasingly, turning around on the spot and fondling her tits, abdomen and crotch.

Benjamin responded by nodding his head as his canine penis quivered and spurted a small stream of precum.

Serena sensually walked over to the boy and sat between his legs, penetrating herself with the teen's hard cock.

The fox gasped at the female's moan as he felt his penis slowly being embraced by the warm, moist folds of his sister's vagina.

“That's it... My little brother is all man,” the girl whispered as she continued to descend, gritting her teeth to withstand the pressure.

The pleasurable tingling the teen was feeling in his genitals quickly drove him wild, causing him to grab both hands on the female's arms and pull them downward, penetrating her until his swollen young knot bumped roughly against her pussy, struggling in vain to enter.

“Oooh yes!” cried Serena, straightening her back and sinking her nails into the male's shoulders as she felt that thick penis claim her insides.

“Hmm! W-Wait! Get on all fours on the bed,” Benjamin demanded, stopping the movement of his hips as he grabbed the girl by the tits.

The female stopped as well, looked the other vulpine in the eyes and smiled. As she rose from between the male's legs, both her vagina and the penis she had been jumping on were dripping with a mixture of clear juices, the product of both of their pleasure.

Serena kissed her brother's lips again before kneeling on the bed, her back to the male, and lifting her fluffy tail.

The boy was facing a beautiful sight: a round, delicate ass that announced the dripping lips of the young pussy, red and barely visible between the female's legs. With this image burning into his brain, Benjamin's penis seemed about to explode, filling his whole body with energy to stand up and position himself behind his sister.

“Come on, little brother... fuck me hard,” Serena encouraged.

The teen fox didn't think a second longer and laid down on the female, hugging her at chest level to grab her tits as his cock seamlessly found its target, sinking back into the wet, warm female cavern.

When Serena felt her brother's hands, her legs trembled, and as she was penetrated again a long moan came from her muzzle until cut off short as the young vulpine began to thrust into her, producing a slight pause after each sound she produced, “Haa! Haa! Ooh! aah!”

Benjamin's heart felt like it was going to explode, filling the young man with an ample excess of energy that he was using exclusively to thrust into the female, already reaching in and out of that dilated pussy with his canine knot.

The frantic demonstration of carnal desire went on for a few more minutes until the male's knot swelled so much that it got stuck inside the female, seconds before Benjamin began to ejaculate abundant and warm sperm that did not take long to make its way into Serena's fecund depths.

Past the violent and abundant first three shots of male juice, both teens relaxed and fell sideways onto the bed, closing their eyes as they caught their breath.

“Wow...that felt good. Looks like you really needed it, little brother,” Serena said, emphasizing the last word.

“Fuck...don't say it like that,” Benjamin replied.

“Why not, your father fucked my mother, that makes us brothers,” the female posed again, this time with a giggle.

“Shhh... shut up,” the teenager muttered, trying to ignore the girl's words as he dipped his muzzle into his sister's neck to sniff the delicate scent of her fur.

For half an hour, the two youngsters alternated between silence and short little chats until Benjamin's knot shrank enough to be able to disengage from the female. From Serena's vagina came a copious stream of teenage seed that quickly formed a small puddle of the thick, white liquid on the sheets of the boy's bed.

After that, both teens took a shower together in which they spent a long time making out and exploring each other's bodies until they ended up fucking again, with the difference that Benjamin was able to resist putting his knot back in so they wouldn't get tied up.

When Serena finished drying her fur, she put her clothes back on, kissed the boy's lips and went home.

Benjamin, on the other hand, stood naked in his room with the lights off, thinking about what had happened, feeling slightly uncomfortable about the possibility of having fucked his half-sister, and without protection.

The clock read nine pm, it was still an hour before the teenager's parents arrived. At that instant, a light scent reached Benjamin's nose, interrupting any deep thoughts the teen was having, forcing him to grab the damp sheets of his bed, pulling them up to his snout as he lay back and closed his eyes before beginning to masturbate to the smelly memory of the pleasurable experience he'd had with Serena, his sister.
