From Tail to Tip
By Winter’s ink

The sun had set. Marlin the middle aged otter sat on the couch and flipped on a porno. Wearing nothing but his boxer-briefs, the old man put his feet up and settled in. Marlin frowned at the sight of his belly. He blamed the size on too many bears in the evenings spent looking after his teenage twins. 

Marlin had the unusual opportunity of an empty house and no plans. His twin boys, Finn and Gill, were sleeping over at a friend’s house. It was rare for his house to know peace, but when it came Marlin knew to take advantage because it would not last.

The old man snaked a hand down his underwear and pulled out his semi hard humanoid penis. The elastic waistband tucked neatly under his big furry balls, propping them up and defining the large orbs. Marlin began to tease himself, pulling on the little bit of foreskin that covered his cock head. His attention now turned to the actors in the porno. His eyes slid over the young bodies in the film, the female and the male too.

In the other room a key thrust into the front door and it crashed open.

Marlin groaned. I should have picked something with less foreplay. 

The adult changed the T.V. to the first PG movie he could find and, with practiced ease, tucked his member back into place. Moments later, Finn stomped into the living room.

“Where’s your brother?” Marlin asked.

The twin otters had been figuratively joined at the hip since birth. Gill used to climb out of his crib at night to be with his brother. They did everything together and shared a special connection that only twins could. If Finn came home alone that means something serious must have happened.

“Gill’s a butthead and his stupid friends are buttheads too!” Finn yelled, slamming the door to his room.

“Watch the language!” 

Finn was upset and likely wouldn’t care about the reminder to speak nicely, but it was still a rule in their house. Marlin learned very quickly that rules had to be clear and unbending, lest they be broken by the sharp minds and quicker tongues of his kids. 

Five minutes passed before Finn stalked quietly out of his room. The thirteen year old had changed into his purple pajamas and dragged a blanket with him. He shuffled over quietly to sit on the couch and rest his head against his fathers furry chest. Marlin knew better than to comment on the boy’s puffy eyes and sullen frown. So instead, he just wrapped an arm around his son, pulling him close.

“You wanna tell me what happened?” Marlin asked over the barely audible dialogue of the movie.

“No,” Replied Finn.

Yes you do, Thought Marlin, It’s all over your face.

Fights weren’t common between his sons, but when they happened they were vicious. The boys knew every aspect of the other’s life, so naturally they knew exactly what would cut the deepest. Neither of them took half measures in anything, a trait they got from Marlin, which usually led to even the small fights turning nuclear. In the end they were still brothers. Tempers cool, they apologize, hug, find a quiet place, and have make up sex.

Marlin knew his sons had sex. It wasn’t hard to figure out considering how much they did it. He still remembered when they were 9; Marlin had walked into their room without knocking. Gill had his legs spread with a starry eyed expression on his face, the newness of it all hadn’t worn off yet. Finn was eagerly sucking on his brother’s little prick and shouted, ‘Daddy this is private!’ when he noticed the intrusion. The naked little boy stomped over, pushed Marlin out of the room, and shut the door in his face. They had ‘The Talk’ shortly after that.

Most fathers might not be too thrilled about his sons boning, but Marlin knew they would be experimenting with or without his approval. He too was once a young boy feeling the first stirs of puberty and he knew the kind of damage a resentful father figure could do. Marlin wasn’t going to make his boys go through that. Instead, they talked. Marlin imparted the importance of safety and consent, and the three of them grew closer and more open. However this openness came with its own challenges.

“Dad, can I see your penis?” Finn mumbled his question, already knowing the answer.

“No, son,” Marlin replied, kissing him on the top of the head.

Finn was 10 the first time he asked for a sexual favor.. For a split second Marlin considered what it would feel like having such young lips tasting his cock. But he shook his head, reminding himself he wasn’t an impulsive teenager anymore. Marlin didn’t know how crossing that line of intimacy might affect his relationship with Finn, or more importantly Finn’s relationship with Gill.

“Tell me what happened.” 

Finn sighed, pushing his face into his dad’s furry chest. 

“It was supposed to be just me and Gill sleeping over at Tom’s house. I don’t really like Tom but Gill does so I went anyway.”

Finn got quiet. He idly played with a tuft of Marlin’s fur while he worked out how to say the next part.

“We had been fooling around with Tom, for a little bit, at school.”

Marlin frowned, his displeasure abundant.

“I know we’re not supposed to but we did it anyway. They wanted to have a sleepover so we didn’t have to be so careful.”

Finn pulled his blanket closer around himself, “But Tom brought over one of his friends from the basketball team. He said they touch each other in the showers after their games and wanted to stay for the sleepover too. But they really just wanted me and Gill to do to them what we did for Tom.”

“You didn’t want to do that.”

“I told Gill I wanted to leave but he wouldn’t listen. He said-” Finn pulled the blanket up over his snout, like hiding his mouth might shroud the meaning of his words. “He said once I get a dick in my mouth I won’t care who it belonged to. So I shoved him down, said something even meaner and left him there alone.”

Finn pulled the blanket over his head, hiding eyes flooded with tears. Marlin held on tightly to his sons trembling shoulders. He searched for the right words to comfort his son but nothing was even close to good enough.  

“Dad, do you think he’s going to come after me?” Finn asked through snot clogged nostrils.

Every fiber of Marlin’s being wanted to say ‘yes, everything is going to be okay,’ but he knew that Gill likely wouldn’t. At that age Marlin wouldn’t have, not when sex was his other option. 

Instead Marlin said, “Let’s watch the rest of this movie and we can wait for him together. How does that sound?”

The young otter sniffed back his tears and nodded. Together the father and son watched and waited. The movie ended, another started and then that one ended too.

Finally, Marlin had to move or he risked spending the whole night on the couch. He picked up his bleary eyed, half asleep son and carried him to bed just like he used to do years ago.

Finn stirred, “Dad?”

“Yes?” Marlin whispered.

“Can I sleep next to you tonight?” 

After a pause for thought Marlin agreed and took the boy to his bed. They both slept soundly holding each other’s paw.

—

The next morning Finn blinked awake in an unfamiliar bed, with a great furry heat beside him. His dad was a lot warmer than Gill and the sheets enveloping them had a pleasant scent. Marlin was already awake, but he stared at the ceiling lost in thought. Finn wrapped an arm around his father’s great chest.

“Good morning buddy. How are you feeling?” Marlin asked.

“A little better. Thanks for staying with me.”

“Say, I’ve been thinking,” started Marlin, “You and Gill, despite being twins, are very different. And one of the ways you are different is in the way you show love. Gill’s love is like a shotgun blast. It’s wild, uncontrollable, and messy. Gah gah gah!” The older male mimicked firing a big gun through the air, “It gets all over the place, I think you know what I mean.”

“Okay,” said Finn, holding back a chuckle.

“The way you show love is deep. There isn’t a lot that you love but when you love someone you really love them. With all your heart and soul and every strand of fur from tail to tip, you love them.”

Finn was quiet; he looked away with a blush on his cheeks.

“What I am trying to say is that it’s important to remember you both experience and show love in different ways. Your love has different wants and different needs. Sometimes those ways of loving clash and you have a fight. But you still don’t stop loving each other because you’re family and that will never change. I’ve been treating you and Gill the same for a long time and I am sorry for that. You two are very different boys and you reminded me of that.”

“Dad, you know I love you too. Your strong arms, your handsome face and even your big belly.”

Finn slid a hand over his father’s gut. His fingers pushed through the older man’s fur and over his navel.

“I know, son,” Marlin caresses his son’s cheek with a big paw. 

 “Can I show you then? Show you just how much I love you?”  Finn starred with big eyes, “While Gill is showing his love to someone else, I want to be with you, showing you mine.”

Marlin’s heart leaped in his chest. He had walked into another trap laid out by his son. No, not a trap. By the way Finn looked at him, by the way he cuddled into his chest, Marlin knew that Finn’s actions were not born of lust. Marlin had blinked and his son had matured, or maybe he was always this way and Marlin just couldn’t see it before.

“You don’t have anything to prove, I already know how much you love me. But if you’re serious,” Marlin tried to swallow but his mouth was dry, “I’d really like that.”

“For real?” Finn said.

Marlin nodded. “But let’s keep this between us.  I wouldn’t be able to handle your brother’s persistence if he started asking for sex too. This is a special occasion for just the two of us.”

Finn nodded thinking about the two people he loved the most. Gill hadn’t shared Finn’s interest in their father, despite showing interest in everything else with two legs. Keeping this new development from Gill wasn’t malicious, it felt like his dad was a glass of apple juice and his brother was milk. His love for them was equal but mixing them would turn it sour.

Marlin lifted his hips off the bed, allowing Finn to push down his underwear. His cock strained against the tight band as it slipped further down his length. The bulging veins along his shaft betrayed just how excited the older man was. His cock sprung out into full view and slapped Marlin in the chubby belly, eager but patient. 

“It’s so big.” Finn stared, entranced by his father’s manhood.

Marlin’s cock flexed involuntarily as little fingers danced up his shaft. They pulled at his foreskin and exposed his head. Finn repositioned, pushing the covers back and crawling between his dad’s legs. The movement of Finn’s body was so light, Marlin could barely detect the weight shifting in the bed. Then hot languid breaths curled around his big balls. 

“Oh, Finn,“ Marlin moaned.

Marlins heart thumped in his ears as his son explored between his legs. Finn’s snout buried in the man’s balls and Marlin’s long cock rested on the boy’s forehead. 

“I think these are my favorite part,” said Finn, “They helped make me after all.” 

He opened his mouth and gently sucked one of his fathers orbs between his lips. Finn’s mouth was warm and gentle around Marlin’s testicles. Hot breaths puffed out of the small boy’s nose, pulling in as much of his dad’s scent as he can take, and tickling his dad’s pubic fur on its way out. 

Finn moved, letting the saliva coated ball slip from his lips. He turned his attention from balls to shaft. He playfully licked at the root of his fathers penis. It reacted involuntarily at even the slightest teasing. Slowly, he licked a path up his father, stopping often to kiss veins and nibble on foreskin. Marlin savored each little moment. 

“Does that feel good?” Finn asked, looking up at Marlin with innocent eyes.

Finn’s fingers combed through his father’s belly fur. Marlin’s hand came down to meet it, their fingers interlaced and squeezed tightly.

“It feels amazing, Finn,”

The young boy smiled, his fathers cock flexed against his lips. Finn opened his mouth and soft wet lips wrapped around Marlin’s cock head. A warm tongue passed over the leaking tip. The fur on Marlin’s neck stood on end as a wave of pleasure washed over him. A pleased rumbling came from Finn’s chest, the vibrations reverberating through Marlin’s cock. The father and son pair were connected like never before. 

Sucking on his dad was nothing like sucking on his brother. The smell and taste were similar but Marlin’s was more refined, more mature. The attitudes were completely different as well. Sex with Gill was spontaneous, energetic and frantic. Sex with his dad was patient and indulgent, a reward made sweeter by all the years of denial.  

Finn’s tongue slipped under his dad’s foreskin. A low moan escaped from Marlin and his hips pushed forward in another wave of pleasure, trying to get further inside Finn’s soft lips. Finn obliged, aspiring to take in as much of his dad’s fat manhood as he could. Marlin shuddered as half his cock disappeared between his teenage son’s lips. His cock poked at Finn’s throat and the boy struggled to take more.

It was all bringing Marlin to his edge too quickly.

“Finn,” Marlin interrupted by rubbing Finn’s back.

Finn looked up, a trail of spit connecting his smile and the adult’s cock.

“Let’s take off your clothes.”

Finn nodded with a blush. He seemed nervous getting naked in front of his father, despite being naked around him many times before. Marlin helped his son disrobe, his big hands unbuttoned the garment and guided it down the boy’s shoulders and hips. Finn was hard in his tighty whities, a wet spot had formed at its tip. Marlin helped remove those too.

“You’re a very handsome young lad,”

Finn blushed, “I thought you might say I am too small for you.”

The two compared sizes. Marlin was larger in every way. His cock longer and thicker, his balls heavier. Finn’s balls were held in a tight circle, where Marlin’s dangled dominantly.  

“You will grow, and this will too.” 

The older man slid his hand down the boy’s privates. His thick fingers tracing out their features, sliding down his tight balls, and bumping into the pink opening beneath his tail.

They both blushed. Finn’s legs opened just a little wider.

“Dad?” Finn began carefully, “Can you put it in me?”

Marlin hesitated. His finger still rested on his son’s tiny hole. It twitched under his touch.

“I’m a little big. I don’t want to hurt you.”

“That’s just a different way of saying I am too small. I can handle it," said Finn. “Please?”

Marlin ruffled his son’s hair before placing a kiss on his forehead. 

“We can try, but tell me if it becomes too much for you.” 

Marlin retrieved a tube of lubricant from the bedside table. Finn got himself into position, putting pillows under his hips and laying on his back. Finn spread his legs wide and looked on with excitement as his father’s massive body clamored over top of him, the adult sized cock bobbing stiffly as he moved. 

“This might be a little cold,”

Marlin touched his lubricant coated fingers to Finn’s pink little hole. He had purposely used way too much lube, Marlin wanted his son to be as comfortable as possible. He pushed a finger into the boy, testing him. 

Finn clearly had some practice. Marlin could feel how the boy’s muscles relaxed, allowing the adult sized finger to slide into his rear.  Marlin pushed in another. There was resistance as Finn’s anal ring stretched to accommodate both digits. Finn seemed so small from this position, and suddenly Marlin wasn’t sure if he’d be able to penetrate his son without the fear of harming him taking over. 

Marlin loomed over his son. Finn gazed back with wide eyes and a nervous smile. His tail tapped erratically on the bed. Despite the hint of worry in Finn’s expression Marlin also recognized courage and determination. Finn spread his legs wide and welcoming. His little cock was stiff with arousal. His hole twitched with anticipation of his father’s love.

“It’s okay, Dad,” Finn touched his dad on the forearm, “I want this.”

Marlin nodded, swallowing his fears and trusting his son to know the limits of his own body. He leaned over the young otter pup, placing both hands beside his head. Finn’s legs stuck out on either side of his dad’s hips. Finn grabbed his dad’s thick wrists for support. Marlin found himself nearly face to face with his son. Finn stared at him with big brown eyes.

Marlin pointed his cock so the tip pressed against Finn’s lube slicked hole and let his weight do the work. His son’s soft flesh stretched to accept the thick head. Finn moaned underneath him as Marlin sunk deeper into his son’s rear. Finn’s insides constricted and relaxed around his intruding cock, each time sending a wave of pleasure up Marlin’s spine.

“Fu- ah Finn. You’re so tight,” Breathed Marlin heavily.

Marlin’s big balls pressed up against the boy’s tail. Finn’s legs squeezed around his father’s waist, making sure, yes, he had taken all of his father’s length inside of him. Finn moaned at how much it stretched him. Even the smallest of movements sent visible ripples through Finn’s body. Marlin’s cock flexed and the movement reflected in Finn’s bulging tummy.

Marlin pulled his cock out a few inches and watched the mass in Finn’s belly retreat. Then he pushed it back in to its hilt. Finn arched his back and moaned in pleasure. His body squeezed Marlin. Finn’s little hands tightened around Marlin’s wrists, thin legs clutched his waist, and his narrow rear squeezed around his cock. Tears welled up in Finn’s eyes and spilled out around a wide smile.

“Keep doing that, Dad,” Finn touched a hand to Marlin’s cheek.

“You’re amazing, Finn.”

Marlin’s eyes darted between his son’s eyes, swimming with tears and half lidded in bliss. His lips were parted slightly and let out little moans of pleasure as Marlin started slowly fucking his son’s rear. 

He dropped to his elbows and dipped his head lower, silently asking permission to kiss. Finn pulled his dad down the rest of the way. Their lips met as Marlin drove his dick deep inside his son with a passionate ferocity. Finn’s arms wrapped around Marlin’s neck as the pair locked themselves into the deepest kind of embrace. 

Mouths parted for a breath and the two twisted their heads to get as much of the other’s maw as possible. Marlin’s meaty tongue spilled into Finn’s much smaller mouth. Their kiss turned sloppy as Marlin started to drive his cock in and out, Finn’s body jolting every time their hips slapped together. Finn did not let the messiness deter him. He kissed his father open mouthed and needy. A kiss that said ‘Let me taste every little bit of you.’

Marlin, overcome by the sensation, growled deep and primal into Finn’s mouth. It sent Finn over the edge. Finn’s small frame tensed up and his insides constricted around Marlin’s cock. The pleasure of climax overtook Finn as he pushed himself down on his father’s penis. Cum shot from Finn’s twitching boyhood, landing between himself and his father’s belly fur. He moaned into his father’s kiss all the while.

“Finn, I’m going to cum too,” Marlin growled, trying to hold his orgasm back just a second longer.

“Shoot it in me, Dad. As deep as you can go,” Moaned Finn, burying his face in the nape of his father’s neck.

Compelled by his son, Marlin rammed his hips into Finn one last time. He forced his dick as it could go, cock spasming and painting his insides white with cum. Marlin filled his son to the brim with familial seed. Marlin’s balls pulsed as they pumped more and more fluid up his length and into Finn. Finn held tight to his father’s shaft, so not a single drop would spill. They both moaned with the delight of it.

The father and son pair remained in the embrace for what felt like an eternity, but not nearly long enough. Their chests heaved as their bodies came down off their highs. Slowly, tenderness and tiredness crept into their muscles. 

“Dad,” Finn squirmed, “You’re a little heavy.”

“Oh, sorry,” Marlin said through labored breaths.

He lifted his weight off his son and pulled his cock from Finn’s insides, feeling a little bit guilty from the gaping hole he left in the boy’s comparatively little body. Finn reached between his legs, his fingers coming into delicate contact with the raised pink flesh and leaking seed. 

“Does it hurt?” Marlin asked, laying down beside the boy.

“A little. But I am still glad I got to do it with you.” Finn said, snuggling into the man’s chest. “You’re the best dad ever.”

With that statement all of Marlin’s guilt washed away. He gently touched his lips to the top of Finn’s head.

“I love you too, son.”
