SMACK
“Nice ass Bro,” Cal said, passing by his twin getting changed. 

“Mmm, you know it, Cal. You've got one just like it.” Coby licked his muzzle and winked as he pulled the jockstrap over his sheathed cock.

The two husky brothers had just started college, and their wealthy parents got the two of them set up in a sizable apartment in the big city. As far as their parents were concerned this was the perfect thing for two young bachelors. They grew up nearly a day's travel from the city where they were starting school, so commuting was a bit impractical. This way they could remain safe and responsible together. Perhaps they'd even find a couple of girls to bring home. However, what their parents didn't know wouldn't hurt them, right? The twin canines were so excited to be away from the prying eyes of their parents…because the two had been intimate with each other since they were 14. 

It started out fairly innocent at first. Coby had caught Cal jerking off after school one afternoon. Of course one thing led to another and they laid side by side after that doing it together. After a few times they began admiring just how similar they were, and found themselves stroking each other on occasion too. Mutual pawjobs became blowjobs in about 6 months, until they went all the way. It was one special half day when they had the house to themselves for more than an hour, and they decided to lose their virginity together. It was weird at first, but after so many things they had already done, that feeling faded fast. The fact that they were identical not only in looks, but their dicks too, made it that much hotter. 

After that day they had fallen in love with each other in a way that brothers shouldn't feel. They didn't care though. Their bond was stronger than ever and they knew whatever happened after high school was meaningless if they weren't together. So, there they were getting dressed for class in their new apartment, admiring their strong bodies and sexy curves. 

“A little risky wearing a jock to class isn't it?” Cal asked as he watched his twin pull a pair of tight shorts over his bulge. 

“So what?” Coby said, wiggling his ass. “You gonna do something about it?”

Cal smirked and walked up behind him. Wrapping both arms around his waist, he leaned over Coby's shoulder and looked down at the obvious lump in his tight shorts. The sight of his still shirtless twin showing off his big package all day got him instantly hard. The already dressed canine felt his cock throb, and swelled in his pants on his brother's ass. 
“I guess it's a good thing we don't have class together. Otherwise I'd be all over you.” 

“Well…we do have an hour yet. You wanna get in a quickie?” 

“Pff, you naughty pup,” Cal chuckled and pulled Coby's head to the side. “I was thinking we could have a nice evening since it's Friday. I was gonna order a pizza, then maybe…” He leaned closer and whispered in Coby's ear, “...let you top me all fucking night until I can't walk.” 

Coby's ears perked up. He hadn't topped Cal in months, as he didn't let him be dominant super often. His twin was much more straight presenting and didn't like being seen as a submissive little pup. Coby on the other hand embraced his sexuality and loved showing off his body whenever he could. This dynamic between the two helped them keep their relationship a secret.
“R…really?”

“I haven't felt you knot me in ages bro, and I really need it.” Cal slipped his right paw down the front of Coby's pants and squeezed the confined sheath in his brother's jock. “Last chance to wear something looser. Otherwise everyone's gonna see your boner all day.” 

“I…huff…” Coby blushed, his breathing getting heavier. “You fucking asshole.” Coby wriggled free from Cal's grasp and ran to his underwear drawer. Pulling out a pair of bright red briefs, returned to the bathroom and shut the door. 
“You better not be lying about tonight!” He called out through the door. 

Cal only smiled and reached down to adjust his pants. While he certainly enjoyed the occasion, he was 100% serious about wanting to bottom. As much as he hated to admit it, he always enjoyed having Coby inside him, and tonight was going to be fun!

… …

Coby sat in a big auditorium classroom listening to an old fox lecture about psychology. It was the last class of the day and the most boring. Even the professor knew it was a dry subject and he didn't bother stopping anyone from texting or falling asleep during class. This was college after all, and if a student failed that was entirely on them. Coby had a seat in the last row while he set his phone to record the lecture. Occasionally glancing down to check on the sound, he most stared blankly at the professor trying to take in all he could. 

As the class was reaching its final 30 minutes, Coby saw his phone vibrate. Looking down he saw a notification from Cal. 

“Hey bro, just thinking about you,” the message read, then an incoming picture started loading. Coby's eyes shot open wide as the picture came through. It was a selfie of Cal. He was in the bathroom across from Coby's classroom, sitting in a stall, and showing off his rock hard 7 inch rocket. A drip of precum was oozing down the shaft, and Cal was pulling at his sheath.
“Like it?”

Coby looked nervously from side to side, double checking no one was looking over his shoulder. Then he typed back. 
“Holy fuck Cal! Are you right across the hall!?” Coby felt his own cock poke from his sheath. He wiggled in his seat as his pants tented under the desk. 

“You know it. You wanna skip the rest of class and come get a taste of your brother's musky cock?”

Coby's heart was pounding out of his chest. He was nearly drooling on the desk at the sight of his brother's juicy cock. He glanced up at the professor then, back at his phone.
“Damn it…I'll be right there you fucking tease!” 
Quietly packing his bag, Coby slipped out of the classroom and across the hall. Stepping inside he saw just a single pair of paws under one of the stalls. Turning around he latched the deadbolt on the door labeled “staff only” and threw his bookbag in the corner. Walking up to the stall door he knocked.
“Open up you sexy asshole.”

A click of the latch and the door swung open. There was Cal, legs spread wide and a devilish grin on his face. 
“Sup bro?” 

“Fuuuck dude!” Coby said, immediately pulling off his shirt and groping his pants. Coby's pants fell to his ankles next, but he left on his tight red briefs. His cock was poking up through the waistband and oozing precum. Climbing onto Cal's lap, he pressed their tips together and grabbed the sides of his head. Their muzzles parted and tongues met sharing the forbidden kiss as twin brothers. 

“Mmmmmm. Hmmm. Mmmmmmph. Mmmm. MWAH.” A trail of saliva falling between them, they stared at each other lustfully. Their breaths in sync, Cal reached between them and tugged at Coby's waistband.

“Wanna trade these with mine ‘til we get home?” Cal asked. “I've been soaking mine in pre since the start of your class, and I need some dry ones.”

Coby blushed and looked to the side where Cal's shorts and undies were sitting. His navy blue briefs had a noticeable dark spot. 
“Oh fuck Cal, that so hot. C…can I?”

“All yours bro.” 

Coby crawled off of Cal and slipped his red briefs off. His matching cock throbbed as he tossed them to Cal and picked up his brother's messy underwear. They were still really warm, and Coby could smell the musky precum immediately. Stepping into each leg hole, he slid them up, then tucked his cock to one side, letting his brother's juices warm him up. Coby moaned, shooting a bit of precum himself which oozed through the wet fabric. 

“Oh yeah, that's my sexy bro!” Cal moaned, pulling the red briefs over his own throbbing cock. “Mmmm, these feel good. Thanks bro.” 
Reaching for his pants, Cal turned and kissed Coby briefly again. “Let's head back. Those undies will probably soak through your pants by the time we get home.”

Coby whimpered and got dressed. They were only a 15 minute walk from campus, but now he had his brother's precum soaked briefs hugging him. The thought alone and the warmth of them kept the husky hard the whole walk back.

…

The twin brothers were barely through their apartment door when Coby pinned him to the wall. He let out a lust filled moan, pushing into a long and passionate kiss. As their tongues fought for dominance, they quickly began undressing one another. Shirts over their heads when catching a breath. Shorts dropped to their ankles. Then was the navy blue briefs Coby had on soaked in his and Cal's precum. By this time his pair of red ones Cal had on gad a big wet spot as well. They were so horny for each other not even the tight cotton could hold back any longer. Hands moving from chest to chest, then down to the band of their underwear, they broke from the kiss and chuckled. 

“Fuck you're so hot, bro,” Cal moaned.

“We look the same, ya know?” Coby replied, slipping both paws down Cal's backside. “My sexy butt is your sexy butt.” 

“So?” Cal smiled. “We've got identical cocks too, bro.” Cal slipped his left paw down the back of Coby, and his right squeezed the soaking bulge in the front. 
“Good thing I got you nice and lubed up.” Cal stepped away from Coby and pulled off his underwear. The red briefs falling to the ground he walked over to their couch and bent over presenting his tailhole. Slapping his ass, he growled and called Coby to him.
“Come get it, bro!”

Coby let out an excited involuntary bark, just about ripping the soaked briefs from his body. Eager and extremely horny, he pressed the tip of his 7 inch rocket against his brother's hole. Grabbing below his already exposed knot, he rubbed a bit of their combined precum over Cal's ass, getting him well lubricated. Then bracing his left paw on Cal's hip, he pushed forward slipping his cock inside.

“AAAH!” Both boys gasped, feeling that perfect unity as their bodies became one. Cal felt his hole spread wide, a feeling he had forgotten was so intense. Coby could feel how tight Cal was, and loved how his tailhole quivered around him. Pushing in further his cock throbbed, spraying his precum deep into Cal's ass. Cal in turn was painting the couch in his own juices. Coby was the perfect size to milk his prostate just on a gentle thrust. It wasn't long before Coby was fully inside with his knot bumping against Cal. Their balls slapped together spiking them with a mixture of pleasure and pain. Then with a knowing nod, the real fun began.

PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

It was a good thing they were the only two in that apartment as their moans grew loud quickly. The wet slapping sounds of twin horny college huskies having sex was unmistakable. Their moans intermittently becoming barks and growls as their raw animal desires took over. 

PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

“AHHHHH. UNNNGH. GRRRRRRRRRRR. RUFF!”

Harder and harder Coby thrust. His throbbing cock spraying loads of canine pre, keeping them both well lubricated. There was so much that they both could feel it pooling near the edge of Cal's hole. It was only a matter of time before…POP! Cal let out a whining yelp as Coby knot was forced inside him. Swelling fast Cal felt the immense pressure as his twin brother tied into him. 

“Oh fuck yes!” Coby moaned, “Here it comes!” Coby grabbed Cal's hips and gripped them tight. A wild climax rushed through his body and he blasted a monstrous load of cum deep into Cal's body. 

“HELL YEAH! Fill me up good, bro!” Cal reached back behind his own knot and squeezed hard. The pressure around his cock made him clench tightly around Coby involuntarily. He laughed hearing how much his body was making his brother moan. Though he himself was far from climax, the feeling of Coby's hot husky cum filling him to the brim was still amazing. He could feel every pulse of Coby's knot as nearly endless streams of cum swelled his belly. 

Coby panted catching his breath as the last spurts of cum surrounded him. He could tell his swollen knot was the only thing keeping the flood of his cum from escaping Cal's body. Reaching around Cal's front, Coby replaced Cal's paw with his own, squeezing under his brother's knot to keep him tight. Coby licked the back of Cal's neck, then across his face, and turning his head slipping into his muzzle. 

“MMMMMM. HMMM. MMMMMMPH. MWAH!”

“Fuck bro, that was intense!” Cal said, letting a trail of saliva fall between them. “I've really missed having you breed me like that. Hope you've got more that that in you, though.”

“That depends,” Coby teased him, “Am I allowed to pull my knot right here? Or would you rather not have to scrub the couch again?”

Cal whimpered in his deep and needy voice. “Can you carry me?”

“Of course,” Coby replied. 
Lifting up his twin, Coby slowly walked them to their bedroom. To his surprise, Cal had already laid several towels across the sheets anticipating a wet and wild evening. Gently placing Cal down so he was on his paws and knees. Then once settled Coby arched one leg up and over Cal's back. 

“Whoa what are you…UNGH FUCK, BRO!!!”
Cal was pleasantly surprised to see and feel what Coby was doing. Twisting around like a feral dog, they were now ass to ass and Coby was tugging his swollen cock. 
“Holy shit bro! This feels so…ungh, goood!” 

“You love being my bottom pup don't ya, Cal?” Coby teased him while starting to tug. “All that tough exterior, you're just a submissive softie.”

Cal whimpered. His brother was taking full advantage of his plan to bottom tonight. As much as he wanted to stay quiet that would prove impossible. Coby tugged harder, yanking out his knot with a loud POP!
“AAANGH BRO!” Cal moaned, tailhole gaping and oozing his brother's cum down his legs. He collapsed forward onto the bed and turned his head. Eyes shooting wide he was stunned to see Coby quickly turning around and grabbing his ankles. Yanked to the edge of the bed, Coby flipped him over. Standing over him, Coby pushed his tip back into Cal by pulling him up by his ankles. 
“Oh fuuuuuck!” Cal moaned watching Coby's 7 inches side back inside his aching cum soaked tailhole. 

“God you're so hot when you moan like that, Cal. I fucking love you so much!” Bumping his knot up against Cal's body, Coby crouched slightly letting Cal's legs fall loose. Now firmly in a perfect piledriver position he began aggressively thrusting once again. 

PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

The brothers moaned and grunted. Their eyes locked on one another, tongues hanging out panting, and a trail of saliva falling from Coby into Cal's mouth. The bed squeaked rocking back and forth as their forbidden love was on full display.

“Oh fuck bro! Y…you're gonna make me…c…cum.” Cal could feel Coby pretty much destroying his prostate with every thrust. It was like looking in a mirror as his twin brother ravaged him. 

“Yeah, be a good boy and cum for me,” Coby said, one paw reaching for Cal's dripping cock. He gripped tightly behind Cal's knot and squeezed. The pressure caused Cal to clench his tailhole just in tip for Coby to force his knot in once again  

“AAAAAAAAAAGH!” Cal screamed, his body shook as the pressure of Coby knotting him while squeezing his cock was just too much. His cock throbbed, spraying several thick ropes directly into his own mouth. Coby smiled wide watching his twin catch and gulp down his own hot seed while he was buried inside.
“OH FUCK YES BRO! I LOVE YOU TOO!” 

With the last of Cal's cum dripping into his own mouth, Coby repositioned them again. Reaching underneath Cal, he pulled him up, fell to the side. Then lifting one of his legs, Coby got himself in between Cal from the front and grinded his hips so his knot was tugging and throbbing inside. He wasn't about to pull out so roughly again. Instead he continued thrusting and grinding as his knot swelled inside his twin brother's tailhole, tying them tightly together. 
“Mmmmm, we're getting stuck Cal. How's it feel to have my cock inside you? You love being your bro's gay bitch don't ya?”

“Fuck you, bro,” Cal grumbled gritting his teeth. He was so embarrassed by how much he loved being a bottom, especially after swallowing his own cum. 
Coby chuckled then let Cal's leg fall back to the bed. With a little twisting he snuggled up behind him, keeping his throbbing cock buried inside. Hugging his sexy twin tightly he licked up his back, around his neck, then slipped his tongue into Cal's muzzle as he came inside him again. 

“Mmmmmm. Mmmmmmph. Mmmmmmm. MWAH!” 
Their tongues danced over and over as Coby filled Cal to the brim. The flood of it all added even more pressure around the knot and Cal could feel his own cock being milked of that sweet nectar as fast as his body could produce it. Coby reached around and rubbed Cal's cock gently l, making sure not to overstimulate him. 

“Thanks bro,” Cal said with a sigh of relief. “God, your knot feels so good.”

“I know…you've got one just like it,” Coby chuckled, rubbing Cal's precum around it. “So… you think you can still walk?”

“Ummmph. Not sure,” Cal replied, wiggling his hips, feeling Coby's knot pressed tightly against his prostate. “But either way, I don't think we're going anywhere for a while.” He looked at Coby with a satisfied lust and kissed him on the nose.

The twin huskies remained tied together for nearly an hour. Snuggling in each other's arms their bodies felt as one, perfectly connected, and made for one another. The forbidden love the two shared always made them feel closer…and being tied by their knots everyday day made that love even better!
