"Now remember boys, Santa won't bring you any presents unless you're asleep.  That includes the entire time he's here," their father said.  Fourteen year old Rick kind of smirked at the statement.  The fox had discovered the truth behind Santa years ago.  But his six year old brother Tyler was still a firm believer in the jolly old man, so the family made sure to keep the tradition going.

Hours later, it was time for bed.  As they did each year, the brothers went downstairs and set themselves up on the couch.  They laid facing the tree, with the fireplace warming their heads.  Rick covered his brother and himself with a blanket as the two snuggled up tight.  Tyler wiggled against the older fox and let out a contented sigh.  "Do you think Santa will come soon?" He asked.
  Rick looked at the clock on the far wall and noticed that it was nearing Midnight.  "Yeah, he should be here soon." He said.  Tyler smiled and wiggled his butt, which Rick knew was a cute little thing Tyler did when he was happy.  But Rick had other plans in mind.
  Slowly but surely Rick pulled his pants and underwear down, exposing an erection that had gradually built as the two had been laying together.  The younger fox felt what was going on and tried to protest, but was cut off when he felt his own pants and undies pulled down and a couple fingers started to massage his privates.  Tyler moaned while the larger fox's hands started caressing his body.
  Rick reached into his pocket and pulled out a travel sized bottle of lube.  He squeezed some onto his penis and rubbed it around, and put some more on his finger and stuck it up his brother's anus.  The smaller fox moaned louder, feeling the single digit enter and start poking around inside.  It rubbed up against the young boy's prostate, which sent chills up and down his spine.  But just as he was starting to enjoy it, the finger pulled out.
  "Ready?" The older fox asked.  Tyler nodded in response, and in one swift move he was filled with his brother's throbbing erection.  The boy gasped and shuddered, but he soon relaxed and groaned.  He felt the fingers return to his genitals.  They massaged his balls and stroked his tiny shaft.  Soon he too had an erection, and he could feel the intense sensation build.

Suddenly the boys heard the clock strike twelve, and they soon heard the familiar thumps of boots walking their way.  They both knew that Santa had arrived.  Young Tyler shut his eyes and did his best to control his breathing.  Rick, meanwhile, kept his eyes open and smiled as Santa looked at the two.  Santa noticed the older boy's gaze, and he returned the smile.  He noticed the younger boy was blushing, trying desperately to keep his eyes closed, and was sweating while a dull smack noise came from their hips.  Santa stifled a chuckle and gave the older fox a thumbs up before turning around and going back to delivering presents.
  The whole time Tyler was petrified.  The sensation was growing by the second.  He felt his brother's penis twitch inside his body, and it kept hitting that special spot.  He tried so hard not to, but he let out a weak moan.  He could feel Santa looking at him.  Watching him.  Judging him.  He hoped he wouldn't be discovered as being awake.  He couldn't imagine what would happen if Santa left and took all the gifts.

Rick refused to let up, and instead went at his brother even harder.  The warmth of Tyler's body was magnified by the blanket.  It felt like an oven, and the muscles would frequently clench as if to try and milk him of everything he had.  He thrusted harder and faster, and made sure to rub and tease his brother in all the right places.  And just as Santa had finished putting the last present under the tree, Rick let out one more thrust and exploded, his seed coating his little brother's rectum.  A second later Tyler's body started to spasm as he was overcome with his own orgasm.

As their orgasms rushed over their bodies, Santa drew near and was mere inches away from young Tyler's face.  The young fox was still foggy after his climax, but knew enough to keep his eyes shut tight, and he still tried to control his breathing.  He heard Santa chuckle, and the boots started walking away.  Tyler took a quick peek and noticed the presents were all there, and he let out a sigh of relief.

Rick watched as Santa leaned in right up to his brother's face and chuckled.  He gave the boy another thumbs up before walking to the stairs.  Santa climbed the stairs as quietly as possible, making sure to skip the creaky step.  Rick knew where the costume would go, as he had found it once when searching for Christmas presents a little early.  His attention turned to his brother once he heard the sigh of relief.  Rick put his arms around the younger boy and held him tight.  His erection slowly softened and it gradually exited his brother's nether region.  Semen started to leak and stained both boy's fur, but they didn't mind.  Joined together in a warm and loving embrace, the fox boys, brothers and lovers, fell sound asleep.
