The Other Night Fury Research

Hiccup looked around the clearing for the elusive night fury. It seemed that his new friend was hiding from him. The young viking shrugged and found a place in a nearby bush where he could wait for him to return. It wasn’t a very big area, but there were still a few small caves in the rocks where the dragon could hide. Hiccup thought to call for him, but he still was cautious regarding the wild creature. Opening his notebook, he watched closely looking for any movement. 

Just as Hiccup could feel his eyes droop, a familiar and deep fluttering sound echoed in the valley. He jumped, and focused his attention forward as Toothless emerged from behind a few large boulders. The dragon was moving slowly, listening to his surroundings carefully, making sure no one was around. Hiccup could tell that the dragon was moving a bit differently than normal, but couldn't figure out what was going through its head.

Finally relaxing, Toothless let out a long breath and laid back on the ground. It was an unusual position to see a dragon in, but not totally uncommon for Toothless. Hiccup watched as the black dragon spread its legs open and lurched forward. 

"What's he doing?" Hiccup wondered, getting a perfect view of the dragon's body. He wouldn't wonder long as Toothless licked at spot just before his tail. The night fury lapped his lower body, as it made a fluttering hum. 
"Is he cleaning himself or…oh…OH!" Hiccup's face turned a beat red as he saw the tip of the dragon's purple member peak through its slit. Toothless continued licking the space above his slit until his entire length had emerged. Hiccup’s hand shook as he began drawing. 

The night fury was now focused on his erection intensely. Sticking out his tongue further, he licked from his slit all the way up to his tip several times. His thick reptilian cock had bulbs and spines running up the backside of the shaft. Hiccup estimated it to be nearly as long as his own arm, if not even longer. As he licked, short bursts of precum escaped, and mixing with saliva pooled into the lower edge of his slit. 

Looking up from his page, Hiccup’s mouth hung open as his reptilian friend took things a step further. Opening his jaw wide, he dropped his head down taking the entire length into his own mouth. The young viking was stunned as Toothless bobbed up and down sucking on his giant cock. [Hiccup felt his own dick twitch in his pants at this sight. "Oh Gods this is kinda hot," he thought, closing his notebook and setting it aside. His right hand slipped beneath this belt and he began stroking his boyhood while watching Toothless devour himself.]
The dragon slurped loudly, rolling his cock around and around inside his mouth. He had been pent up for days and his natural desires had now taken over. The dragon needed release. He had learned years earlier how to pleasure himself orally after seeing another male do the same, and found the act to be very satisfying. Toothless roared lightly into his groin, starting to buck his hips involuntarily. The motion forced his purple throbbing cock deeper into his mouth and down his throat. His internal muscles squeezed just enough to send waves of intense pleasure through every nerve in his body. 

[Meanwhile, Hiccup had leaned back on one hand, and opened the front of his pants. His right fist was tightly wrapped around his boyhood as he pumped it furiously. Twisting his fist every few strokes, he could feel himself leak from the sensation.
"Oh Gods yeah!" he thought, "I wish I could do that!"]

It wasn't long before the pleasure had become more than Toothless could handle. His body shivered and he pulled back his head just as a fountain of cum erupted from his tip. He let out a guttural roar as hot liquid splashed back down coating his body.  With waves of pleasure calming down, Toothless looked over himself. He took a deep breath then to Hiccup’s surprise the dragon licked himself clean, gulping down his own cum. 
[Hiccup looked at his own hand which was slightly wet from his precum. Raising it to his face, he copied Toothless and licked the liquid from his fingers. It didn't have much of a flavor. It just had a strange slightly slick texture. The young viking knew it was likely because he had barely started puberty and he hadn’t yet experienced his first orgasm. Though he was doubtful he would be able to produce as much cum as his dragon once he did. They were different species after all.]
The night fury's cock slowly disappeared back into its slit just as he finished cleaning up. Hiccup watched as Toothless rolled back over and laid on his stomach looking satisfied. He decided it would be best to keep his observations to himself that day. After all, trying to explain how he learned about a night fury's self pleasuring habits might be a bit awkward. 
[While he was still exposed, Hiccup moved to stand when his right foot caught a branch.
CRUNCH
His gaze darted between his foot then back out to Toothless. The dragon's acute senses finally picked up on Hiccup’s presence and the startled dragon leapt into the air. Hiccup stumbled backwards, reaching for his belt, but as he scooted across the ground his pants were pulled to his ankles. Sliding out of cover he looked up just as Toothless pounced down in front of him. The dragon looked at him curiously.

"Oh, uh, hey bud," Hiccup said nervously. "I was just uh…" As Hiccup tried explaining himself he saw Toothless' eyes glance down to his exposed body. The dragon sniffed the air recognizing a familiar but mild musk. Eyes looking between the young viking's face and crotch, Hiccup realized what Toothless was looking at. 
Panicked he sat up and reached for his pants, only to have Toothless lurch down and grab his pants with his teeth. Pulling upward, the dragon yanked them off Hiccup’s ankles and tossed the clothing aside. Leaning down Toothless inspecting Hiccup’s package curiously. 

Hiccup was frozen. He didn't know what to think or do at that moment. Luckily for him though, Toothless already knew what his human partner needed. Opening his mouth, Toothless let his tongue flop out and hover next to Hiccup’s boyhood. Before the young viking could react, the dragon licked upward across his entire package. 
"Ah!" Hiccup gasped feeling his partner's warm and wet tongue roll across his privates. "T…Toothless!?" The dragon hummed as his tongue rolled up and down on Hiccup. Though he had never seen a human's dick before, Toothless was confident Hiccup felt the same pleasure that he did when stimulated. After all, he was already exposed to him. 

Hiccup gasped and he hunched forward hugging Toothless. The feeling of having a dragon work its tongue across his boyhood was incredible. It felt much better than the bit of rubbing he could do on himself. The strong tongue forced his foreskin to roll back and forth, perfectly stimulating the tip. His small balls also received a thorough message as well. Though it was unusual, it was far from painful. The added stimulation was beyond what the boy thought was even possible. 
"Oh, Gods! Toothless!" Hiccup suddenly  clenched his hands tightly on the dragon's head. His hips involuntarily thrust forward, his back arched, and every muscle in his body tensed.
"AAAH!" He shouted, and a powerful stream of clear boy-juice shot across the dragon's tongue. 

Toothless closed his eyes, letting his partner's young cock throb, as the last of the thin prepubescent cum dribbled out. Pulling his head back, Toothless licked up all of Hiccup’s liquids, and gulped it down. The dragon then remained close, waiting for the human to respond. 

Hiccup panted, catching his breath. He couldn't believe it. This was his first ejaculation EVER and it was all thanks to a dragon. "Oh, Gods." Hiccup gasped. "T…that was…wow," He fell back exhausted. The young vikings limp boyhood, dripped a small bead of cum onto his leg. Toothless hummed and laid down beside him. 
… …

It would be almost an hour before Hiccup would finally acknowledge the dragon again. He sat up and looked down at his boyhood, then over to the dragon's slit. Sighing he smiled knowing that they both seemed to have the same needs that day. Hiccup didn't really mind that they were both boys, because they were friends…and after that day were inseparable. 

After saving his village and through the years they spent together the two would grow even closer. Though Astrid had her suspicions, she never found out what the two best friends had done…over and over and over for as long as they were together.]
