Aiden chased Avery up the pebbly slope of the beach from glassine waters, the pristine expanse broken only by the dying ripples of recent frolicking, and into the short tufts of dry, bristly grasses at the periphery of the glacial alpine lake not far from their quiet mountain town.  Even late into summer, the water was frigid, but it suited the boys just fine; the mountain dwelling, thick furred lynxes were well insulated against the cold, even when running nearly nude, sodden, and fresh from its icy clutches.
	In other places about the lake, seen in casual glances made in speedy darts, spins, and childish manhandles, the many elderly tourists in motorboats way out in the middle cast their rods, swam, or idled in the shallows and shadows where the cool breeze coming off the surrounding, snowbound peaks offered the best reprieve from the summer heat.  The stunted, wind-seared trees were but another twenty foot dash away(and the scree of the mountain another fifty), but Avery could wait no longer, and lunged for his twin.
	Grabbing for his middle, he landed his tackle, bringing Aiden down like a yearling ibex in the stiff brush, hand digging already past the hem of his trunks, and feeling up his chilled, flaccid member.  His foreskin was peeled partway back, and his usually perky package was drawn tight against the cold, his warm fingers bringing much needed heat and life to it.  
	“Avery!  Come on, lets get to the trees!  You don't want everyone to see us, do you?  We can't risk Mom finding out again!”
	“Let them, I don't care!”  Avery said, more bravely than he felt.  “It's not like they can do anything from out there!  It would take forever for them to get to dock and back!  Besides, I don't know who that bloke out there is, but it isn't Mr. Barkley, and he's the only fur from town with a boat that nice.”  
	Aiden persisted halfheartedly, holding up his knees and batting at him ineffectually, fending off his twins advances scant seconds longer, then let his hands fall in submission.   He didn't say anything more; Avery was right, and he knew it.  And if he was totally honest with himself, the idea that a stranger might see them turned him on rather a lot.  
	And, as he thought more and more on it, and his brothers hands fondled and fumbled, his penis stiffened, catching the draw-string of his swimsuit and providing a new obstacle to being disrobed.  Even helping his brother along now by lifting his butt from the ground and pulling his tail free, it impeded them with rather surprising effectiveness in their gaining haste.  Undaunted, Avery ceased trying.  He let Aiden's swim shorts snap back up around his waist, and began to minister to him through the water logged cotton.  
	The baggy cloth filled Avery's muzzle unpleasantly, but he was able to close fully over Aiden's cocklet.  The cold, wet suit contrasted strongly with the sudden warmth of his muzzle over that one part, and what little bit his dick could stiffened that little bit further, foreskin rolling back to expose the tip to the rough mesh of the swimsuit's interior.  It was abrasive, and the motions of his brothers tongue massaging the fabric made it rub directly on his head.  
	“Ah, c-careful!”  
	Muzzle filled with cloth and cock, Avery garbled an apology that made it chafe more, but he reticently halted the liberal use of his tongue, and began suckling instead, looking Aiden in the eyes, and watching for discomfort.  
	The sensation was strange, but pleasant; Aiden could feel the suction, though not as strong as it would be against his bare penis.  Nor was it quite as warm.  Traces of cool air filtered in where the suit expanded out of Avery's muzzle to cover his hips and buttocks in a cool blue and white prison.  But he could also feel the water aerating against his shaft, micro-bubbles forming and popping all over his flesh rapidly, and it tickled and tingled in wonderful ways.  
	He didn't notice his fingers gripping the hem of his suit again, lost in the unique sensation, until the sensation stopped.  Avery pulled his suit down with greater care this time, hand gently removing his penis from it.  The downward motion of his suit stopped at his knees, and he agreed that was quite far enough, and was glad when the protective warmth of his muzzle wrapped around his prick again.  For all his love of the cold, he didn't enjoy that part of him being quite so chill.
	The moist, sand-papery feel of Avery's tongue dipping between his foreskin and glans was intense, but not on the level of the mesh.  It was the perfect amount; it was the amount he was used to, the amount to be expected when it was played with, and the amount which without, he would never be quite satisfied getting his little rod sucked.  He knew it intimately, and craved its long strokes around his shaft, tugging at his foreskin, and across the head.
	“I love you,” Aiden sighed, cupping his cheek.  Avery's eyes flashed up at him, head still bobbing, humming his affection.  The vibrations traveled through his dick, urethra probed now by the tip of that amazingly textured tongue, and he could feel it defusing through his hips and pelvis.  He moaned, and humped unexpectedly into his muzzle.
	“I'm sorry.”  
	Coughing, Avery sat up, and wiped his lips of spittle.  “It's okay.  Lift your legs.”
	He obeyed, and Avery pulled the obstinate swim-trunks off him, then shuffled back to remove his own.  Between his legs, his proud erection was revealed, identical in every way.  From its ramrod straightness and slight upward arch, to its length and girth, and its exact right amount of foreskin, it bounced excitedly over Aiden.  Beneath it, his testicles held close to him from the chill, wrinkly, but cute all the same.
	Slow and deliberate, he pulled him into his lap, and spread his twins legs, holding him close.  He felt them wrap around his lower back, water held in their fur squeezed out, pattering gently in audible drips to the ground.  Closer in he came, laying his rigid prick along Aiden's, their wet, pink flesh rubbing together, foreskin catching at and drawn back past the head of his cocklet, the motion and friction warming him, and his pouch sagged in relief. 
	“You know that makes us gay, right?”  Aiden asked, feeling his brothers testicles coming to rest on his.
	“You dork.  Don't do that.”  Avery bopped him reproachfully on the nose, then reached between them and took their penises in hand, jerking softly.  They groaned, a joint exhalation of mutual revel in the others body.  
	But, even though they had cum together twice already(once that morning and shortly after lunch), Avery could feel in his exuberance, and the easy stamina of their youth, a passion driven relentlessly forward by hormonal lust and romantic attraction, the edge of a climax fast approaching.  He steadied Avery, taking hand from their penises and applying it to his stomach.
	“I'm close already.” 
	Avery stopped his gentle grinding, and nodded.  “Hold on tight.”  
	Aiden nodded, redoubling his grip, and reached to his cheeks to spread them wide.  A dribble of semen spilled from his anus and tickled him as it dripped towards the base of his tail.  Avery smirked at his earlier handiwork.
	Spreading and hoisting Aiden's legs further under his arms, he leaned over him, supporting himself with a hand on either side of his face, penis sliding effortlessly into his crack, coming to a rest in the usual well practiced maneuver.  He could feel the semen, still warm, kept safe inside but for the little that had leaked out, gooey and slippery.  Right into the divot his pucker made, sunk in just that tinniest little bit, resting against it, ready to plunge in.  But he held back, pushing, almost slipping into his welcoming embrace, but not quite, then away, nearly sliding out from between his cheeks.
	But Aiden would have none of it, and upon feeling his brothers glans press teasingly to his hole the second time, he clenched his legs, pulling him into his body, and felt the soft, rubbery tip of his dick delicately spread him open.  He tilted his head back, chest rising from the ground, moaning eagerly.  
	Avery, in love with the sensation of being inside Aiden, still had plans to tease, and made to pull out.  
	Vice-like, Aiden clamped down on the retreating cocklet, and released his leg hold, twisting furiously, hard enough to throw sand and pebbles.  Taken by surprise, Avery watched the world blur, body whirling, and felt the back of his head poked by the stubby grasses.  
	“You let your guard down.”  Aiden laughed.
	“So I did.  What'cha gonna do, now that you're on top?”
	“Why tell you, when I can show you?”  
	In spite of his gripping, and keeping him close, Avery had slipped from him.  He reached back and took his twins slender penis in hand.  It was warm and stiff, it's pliant firmness making him shudder pleasantly, his rod responding with a visible twitch.  But, it was slick with stale seed, and it slipped from his grasp.  
	Avery gasped.  
	“You okay?”  
	“Yeah.  Your claws scratched me.”
	“Sorry.”
	“It's fine.  Keep going.”
	More carefully, Aiden took hold of it, apologetically tugging, rolling his seed slicked foreskin back and forth soothingly over his tip.  He plated his knees, and lowered.  Both vented soft, husky moans as key went into lock, exhalations vaporous on the cool air. 
	It was growing cooler, the light dimmer, sun sinking between two peaks like a cock sliding between the cheeks of an ass.  But chill or no in the creeping shadow, they felt only the heat of passion, Aiden dropping rhythmically over and over on Avery's dick, and forcing his breaths out in little, pleasured puffs.
	Avery could feel his foreskin rolling as it passed back and forth through Aiden's anal ring, sliding smooth but unevenly into him.  He humped rapidly, going up as he came down, hips straining and coming off the ground.  His brother gasped; inside, a small protuberance of flesh rubbed along the head of his cock.  
	Penis twitching joyously and dripping pre, Aiden vented exuberantly, Avery hitting that spot just right on almost every thrust now, as they worked together harmoniously.  Hips and butt met in a loud, moist, staccato beat.  It echoed off the craggy cliff not far beyond, amplifying the sound, until pants, slaps, slurps, and the occasional giggle became an orchestral suite, hosted by the accidental musicians, out along the empty shore, and over the lake.  
	Mind numbing pleasure overwhelmed them, fingers tightening in damp fur, their duet of moans reverberating back from the cliff.  Aiden's penis strained, and a fountain of white shot forth, landing with a whisper over Avery's chest, pearlescent upon his fur, then sinking quickly into it, matting it.  With each of his few jets of immature semen, he clenched and released.  It restricted his brothers passage, muscles massaging, drawing out a matching spray of seed to coat his insides, milking him, and adding to the pool.  
	For a moment, they lay, a heap of breathless cub, purring, petting, falling from passionate romp to impassioned kiss.  Avery's cock rested now, slick with fresh cum next to Aiden's, trapped between their bodies, rubbing together as they rolled and tussled energetically the whole way down the stony beach, disturbing the sand and giggling until unexpectedly, a splash of cold water went up, soaking them.  
	“Yikes!”  Avery shivered, the heat of their boisterous play whisked away in a moment. He tried to scramble from the water, but Aiden had remained atop, held him pinned, and splashed him.    
	“Quit it!” he yelled, holding his hands up protectively.  Aiden did, instead dragging him further into the water.  Avery's struggling resumed, but was cut short as something warm in the icy water probed at his nethers, and he laid down on him, pinning him there.  The cold had made his cocklet wilt, but that pressure finding its way under his tail made it rise again in an instant, the top half inch of his prick piercing the surface, like the stout mast of a sunken ship.  
	Uncertainty and enthusiasm battled for control of Avery's face.  The pool at home was one thing, and only if no one else was home, and in the woods nearby for sure, but they'd never done it in the lake before.  It was too cold, and to exposed.  At least the grasses had offered some protection, minimal as it had been.
	“Here?” 
	Aiden nodded, pushing further between his brothers thighs, sinking his tip until it rested at his warm back door.  “Like you said, no one can stop us or get us in trouble.”  
	They cuddled close in the water, Aiden finding his way deeper as he clutched his twin's chest, nuzzling into his neck, and pooling their warmth.  
	The cold water was not a great lubricator, and Aiden's cock did not go in easily; but he went slow and gently, and Avery moaned encouragingly.  It was a difficult proposition, and without something to help things along, only his foreskin served to ease his shallow thrusts.  He took his time, drawing as far back as he could, butt breaking the surface of the water, sending little ripples out, then back in, little mirroring ripples spreading through them as he sank back in on loose flesh, a soft splash as his buns slipped beneath the surface.  
	Even at this slow pace, he could feel the resistance.  They shivered in the water, hips coming together in slow motion.  It was a well choreographed dance that may well have impressed a synchronized swimmer.  But the effort left them panting, heat mounting, neither certain if it had anything to do with their movement, their passion, or both.
	“Hey!”
	It was a soft echo across the water, going unnoticed, covered well by luxuriant moans and  turbulent water, stirred up by the pace of their boisterous mating.
	“H-Hey!  You kids!”
	Neither boy had any attention to pay to it.  They were getting close, and Aiden could see it in his brothers eyes.  Were the water not so choppy around them now, or so noisy, he was certain that he would see his penis bouncing in the air, and hear his moans.  
	And Avery could feel it in him too; the picking up of speed, the loss of rhythm, the opening of his mouth, and lolling of tongue.
	“HEY!  WHAT'RE YOU TWO DOING!?  GET OUTTA HERE!”
	Aiden couldn't hold it any longer, his twin's pucker squeezed on his cocklet so hard, milking him for his immature sperm, but he couldn't ignore that yell either.  It was loud enough to peak his worry, and he looked over his shoulder as he released.  There, only a hundred feet away, was the boat.  The unidentified fur in it stood in the bow, brandishing a fist at them, binoculars dangling from the other.
	Avery heaved beneath him, and moaned loudly, squirting three ropes of cum between them.  It splattered along Aiden's stomach, left shoulder, and the side of his face.  
	They came together under the obnoxious yelling and watching eyes of the interloper, evidence of their carnal act glistening across fur above the water line, acutely aware of their loud, breathy moans heard crystal clear.  Perhaps the grand natural space had lured them into a greater sense of security than they really had.  
	But, as he heaved for breath, and his brother pulled his still spasming penis from him, Avery noted that the boater wasn't coming closer.  The water was too shallow for its passage.  Aiden, having already realized this, had turned back, ignoring the shouts, to watch as small pearls of semen rose to the surface between them, mesmerized.
	On the other hand, even if there was really nothing the tourist could do, and had no good way to identify them and find where they lived, Avery didn't much care for being yelled at, and took Aiden by the hand, got up, and ran, cum leaking down his inner thigh.  He tugged away though, and brashly turned and thrust his hips out in the direction of the boat, jerked himself a few times, then turned back, bent over, spread his cheeks, and let some of the seed inside leak out, forming a matching line down his inner thigh.
	The fur yelled insensibly at the two naughty cubs, threats hanging impotently on the air.  Aiden followed fast after a stunned Avery, both laughing and giggling all the way into the trees to dry and head for home.  If they were lucky, they would get home just soon enough to avoid being scolded for being late to dinner.
