"George!" shouted a young fox from the door of the bathroom of his home.

Immediately another fox, with the same color fur and a few years older, bounded up the stairs and approached the waiting little vulpine.

"What's the matter?" the teenager asked, growling.

"Could you get me a towel to dry off?" the boy asked, looking up into the other male's eyes as he covered his naked body behind the door.

"Yes... " the other vulpine replied in annoyance, turning around and heading towards his parents' empty room.

George's parents had gone out of town for a couple of days and he, just turned fourteen, had been left in charge of the house and the care of his younger brother. The younger fox, ten years old, was a cheerful and energetic boy who always counted on his brother for whatever he wanted to do.

George searched through the bedroom closet and when he found a towel he tugged on it, pulling it out of the closet and causing a flash drive to fall out that was hidden in the fabric. The boy was surprised to see the small plastic object, he picked it up and looked at it closely, he had never seen such an object before. The fox put the flash drive in his pants pocket and left the room to give the towel to his little brother.

When the little fox finished drying off, he put on his underwear and went downstairs. Finding his brother in front of the television, who was watching a strange movie. The little vulpine hid and remained silent, watching what was going on.

George had put the flash drive into the television in the living room. Inside the flash drive was a single file, a video. At first the fox thought it was footage of one of the family's births or birthdays, but when the boy played the file he found something very different.

On the screen of the device he could see two males on the bed of his parents' room, one of them was easy to identify by the color of his fur and his height, he was the father of the children, the other was a male that George had seen only twice in his life, he was his mother's cousin, a fennec fox that had the same height of his little brother despite being the same age as his parents. Both males were completely naked, caressing and kissing each other.

The teenage fox's eyes grew wide, shocked at what he was seeing and thinking of his poor mother until a very familiar female voice spoke up, giving directions as she adjusted the camera.

"Enough warming up, honey get on all fours and lift your tail, Nelson is now the male of the house," George's mother said, zooming in on her husband's face, who gulped and nodded.

The adult fox knelt on the bed, bent down to rest his head between his crossed arms, lifted his hips and wagged his tail to one side. Without hesitation, the other male grabbed his penis with one hand and spread George's father's buttocks apart with the other, took aim and plunged his canine cock in, deflowering the vulpine with a twinge.

"What is he doing to Daddy?" asked the little fox, approaching from behind the couch on which his brother lay.

"FRANK!" cried George, startled as he turned off the TV with one hand and covered his erection with the other.

Frank stared at his brother silently, somewhat chagrined, thinking he had done something wrong.

The teen thought for a moment and then said, "We shouldn't have seen this."

"Why not, because they were naked or because the other mister stuck his wiener up Dad's butt?" the boy asked again.

"I-I don't know...I guess they're playing," the older brother tried to explain.

"Turn on the tv again, it looked entertaining!" demanded little Frank, jumping up and taking a place on the couch next to his brother.

"No!" growled George.

"Come on, you liked it too, you were about to do what you showed me with your weenie the other day!" exclaimed the little vulpine, pointing to the bulge in his brother's pants.

"N-No! And don't call it a wiener!" replied George loudly.

"But Daddy told me It's a weenie," muttered Frank, stretching out his pants and looking down at his sleeping penis.

"It's called a cock," corrected the teenager.

"Cock'?" the boy asked somewhat intrigued.

"Yes, it's called a cock because the ridge in the throat of the... " began to explain the fox but was interrupted.

" Much text... Look, I'm doing it like you taught me!" said Frank, who had his cock in his hands, massaging it slowly, getting it harder and harder.

"What the fuck are you doing!" yelled George at the sight of his brother's penis.

"Put daddy's movie back on and take your cock out, let's do it together!" requested the little fox with more excitement.

Strangely, George wasn't that horrified by the idea. A couple of weeks ago his little brother had caught him masturbating, which led the teenager to teach Frank how to do it, it was a logical way out. But today they had both seen their father being mounted by another male so it seemed anything they did from now on wouldn't be so bad.

The teenager sighed, dropped his shoulders and a second later his pants, grabbed his sheath with his left hand and started touching himself, while with his right hand he grabbed the remote again and turned on the TV.

The boys again watched on the screen as the little fennec penetrated the adult fox savagely, making him squeal as the camera focused and zoomed in on the little balls of the top bumping into the back of the man of the house's testicles from behind.

"Look, George, my cock is bigger than yours!" exclaimed the boy, kneeling on the couch and pointing his penis at his brother.

George's eyes widened at the close-up view of his younger brother's genitals, which were actually quite a bit larger than his own. "Frank!" reproached the teenager.

"I wasn't saying that to tease!" replied the boy, lowering his little ears.

"So?" grumbled George.

"From the video, the guy on top of Dad had it bigger," Frank explained.

"What? That's not true," replied big brother.

"That's right, play back the part where they're making out!" replied the boy, pointing toward the TV.

"Fine...but I'm telling you, you saw wrong," growled George, pointing the remote again and rewinding the recording.

In the scene where the two adults were kissing it could be clearly seen that the little fennec's penis was at least three inches larger than the boys' father's.

"I told you so!" shouted Frank.

"Okay...what does that matter?" asked George, raising an eyebrow as he fast-forwarded the video to where they had stood.

"That I have to stick it in you," explained the little fox.

"Are you crazy, you're not going to stick anything in me!" the teenager protested angrily.

"But daddy likes it!" argued Frank.

"But I'm not daddy!" replied George.

At that instant a loud moan was heard from the adult fox being penetrated in the video, and the female voice holding the camera spoke again, "That's it honey, do you like it when another male puts you in your place?" to which the children's father replied 'Yeeees!" with a cry of pleasure.

"See, even Mommy says so!" indicated the little vulpine.

George's anus throbbed as he watched his father ejaculate without touching himself, while the other male continued to penetrate him like an animal. The teenager looked again at his younger brother's penis and grunted.

"Well..." muttered George.

"Well what?" asked Frank.

"Let's try it," said the teen, and began to pull down his pants, kneel on the couch with his back to his little brother and lift his ass, just as his father had done.

"You've got a big ass just like daddy!" exclaimed Frank, as he stood behind his brother. 

"Frank!" yelled the teenage fox.

"What, did I say something wrong?" asked the boy, somewhat startled.

"Just...just put it in," growled George.

The little fox nodded and rested the tip of his canine penis on his brother's hole.

"Put some spit on it," the teen muttered.

Frank dropped plenty of saliva on his cock and carefully moistened it, then the boy spat directly into his brother's anus, re-aimed his canine tip and pushed against the resistance of the teen's rear entrance, pressing until the flesh gave way.

George let out a yelp and clenched the couch tightly with his hands, a slight burning took hold of his ass and his legs trembled. The teenager's sphincter squeezed hard against the thick, hot piece of meat that was slowly working its way inside him.

The boy slipped his hands between his brother's hips and held on tight, moved back a little and then thrust again, just as he had seen the little fennec do with his father. Within seconds, Frank managed to get used to the rhythm, producing a resounding splash each time the boy's knot bumped against his big brother's anus.

"Ooh fuck!" whined George as his brother's penis poked a spot inside him.

"Did I hurt you?" the boy asked worriedly, stopping immediately.

"No! Frank, keep going!" moaned the teenager, pushing his ass back, trying to sink his little brother's penis again.

The little vulpine started moving again, thrusting harder than before, quickly regaining the rhythm he had.

George closed his eyes and relaxed, enjoying how his brother was wildly penetrating him. The teen rested his cheek against the couch as a trickle of drool trickled down the side of his mouth. A slight twinge made him shudder, a strange sensation ran all the way down inside his lower half to the tip of his penis, making it throb as if he was about to ejaculate.

Suddenly everything calmed down, the older fox listened as his little brother took several pictures with his cell phone but George didn't care as he was completely enraptured by the long penis rummaging through his insides. 

"George... you're all wet and horny," Frank whispered, laying down on his brother's back before continuing to ram him with his endless puppy energy.

"That's because... AH! Fuck, Frank! Get off!" cried the teenage fox as a sharp pain suddenly erupted in his anus, causing the young vulpine to writhe in pain and try to pull away from his little brother.

"I can't! I can't!" replied the boy, also screaming as he clutched at his brother with arms and legs, holding on with all his strength.

The knot, George had forgotten. The teenager tried to breathe, but the pain was unbearable, and Frank's knot kept growing, forcing the older brother to cover his muzzle with his hands, sink his face into the sofa pillow and scream loudly as a few tears fell from his eyes.

A good while later the pain had passed. The two brothers had become still and silent. Already having caught his breath and still in the same position, Frank tried to get up, dislodging his penis from inside his older brother.

"Fucking hell..." moaned George as he felt his little brother's long, thick tube of flesh, which had made him cry, slowly slipping out of his swollen, wet bowels.

"Yuck, you've got a gaping hole!" complained Frank as he saw his brother's swollen, dripping anus straining to return to its original size after being stretched wide by the boy's thick knot.

"Frank...Shut up," George growled before sighing and closing his eyes in an attempt to rest.

"George...we're going to have to do it again..." said the little fox with a worried tone.

"Not now, Frank. Maybe next week..." muttered the teenager, still exhausted.

"But Mom said we have to videotape a session before they get back..." warned the boy, not taking his eyes off his cell phone.

"WHAT!" cried George, jumping to his feet.

"Yeah, look," said the little fox, showing his cell phone to his big brother.

"YOU SENT THE PICTURES TO MOM?" the teenager yelled again, grabbing the device with both hands.

"Yes...she said she really liked them but we should talk when they come back. She also said to use the VCR in her room next time we do it," the boy explained.

"Fucking hell..." moaned George again, covering his face with his hands.

"Look, you left a white stuff on the couch! Gross!" exclaimed the younger brother, pointing to three lines of cum his brother had shot all over the couch they had been fucking on.

"Frank...Shut up," growled the teenager.
