[ihadabadday]

For years he had heard tales of the two fins who swan on the surface. They were... Odd. At least that was what he heard. But they still fascinated him. How did they swim? What did they eat? How did they live?

That was how he found himself on the surface, watching... He wasn't sure what it was. It was large and wooden? There were lights and white things. He curled up a bit further on the rock he had perched himself on. He was always worried the brilliant blue of his scales would make the two finners see him. But they only seemed to see what they wanted.

He gasped when the weather started to change, quickly, violently. The wooden... thing... was in shallow water, it wouldn't survive. Especially if it slammed against the rocks. He swallowed and then dove into the water, even as the waves started to grow violent, battering the wooden thing about.

He heard the wood breaking and two finners and things falling into the water.

That's when he saw him. He felt an odd pull towards the two finner. As if it was right.

There was an old tale at home, of soulmates. He had scoffed at it. Ridiculous. But, the pull he was feeling...

He swam towards the two finner, reaching out to grab the man as he was sinking deep into the water.

He watched the... Sherlock in awe. Why had the gods brought this human to him? He swallowed and then gasped when he felt that tongue on his belly.

Oh.

Oh.

John squirmed under the human, trying not to trash his tail too much.

Oh.

"Sherlock..."

[seaweed_writes]

Sherlock stopped mid lick and canted his eyes up towards John, a salacious grin on his face. "Yes?" He asked, then went back to licking John clean. There was a lot more than he had expected.

[ihadabadday]

He whined. This wasn't fair. It just wasn't. Why did the gods do this? He couldn't be with this human. He couldn't walk on land like a two fin.

John settled for running his fingers through Sherlock's hair. He panted as he felt that tongue continue to work over him. All thoughts of his penis slipping back into its sheath faded. He was hard again and he wanted this human. He wanted to mate with this human.

What an odd thought. In all his years, he had never wanted to mate. And now. And now... he did.

[seaweed_writes]

Sherlock had been licking at John's stomach. When he moved back down, he felt John's erect penis press against his cheek.

"Damn. John." He said softly. "Can you guys.. have sex... very quickly again afterwards?" He touched the cock gently, he still couldn't get over how it looked and felt, it was so unlike his own.

God.. what would it feel like in his mouth or...

No, he couldn't think about that. There was no way that it would fit, he wasn't built for the penis of a fishman.

[ihadabadday]

"I... I guess so." He admitted sheepishly. John, he was John now, not Freebazz, didn't know much about his species. It wasn't like they had learning guides.

He shifted a bit against the water and sand, whimpering. He ached to... He wasn't sure.

[seaweed_writes]

Sherlock was torn between being unsure, being aroused, and being concerned for John, he looked uncomfortable.

"Are, you okay?" He asked softly, leaning his head away when John started to rut into the water a bit. He had a feeling that he knew what the fishman might be thinking, but the thought filled him with dread. Even if they had the same idea, he had no idea how or if it would work, or if John would tear apart his insides, if.. that was what was on his mind.

[ihadabadday]

John stared at him. "I need you to mount me and mate with me." He begged, "Please. I need it."

His voice was hoarse and he seemed so incredibly desperate. He needed... The mer whined and shifted on the ground.

"Please."

[seaweed_writes]

Sherlock gulped "I... have.. no idea.." He didn't know where he would even put.. well, anything. He'd see where John's penis came out, but of course that was full right now, as John was still quite erect, and leaking a bit.

"How... " He looked around as best he could, but he had no idea what to do.

[ihadabadday]

John whined and rolled over into his belly. He shifted a bit, raising his hips.

If Sherlock were to look, he could see an opening hidden by the scales. Not unlike a woman's labia.

"Please..." he begged, "Please."

[seaweed_writes]

"Oh..." He said, softly. He figured that was where, well it may look more like a female vagina, but it probably acted more like... well.. a butt. ''

Sherlock touched around it, gauging John's reactions. At first, he touched and explored all around it, before he tentatively pushed the tip of his finger in, then back out, and then again, just a little deeper.

[ihadabadday]

He shouted when that finger dipped in. Yes. Oh yes. He panted and squirmed a bit.

"Sherlock..." he moaned.

John had no idea if the mating would be successful since they were different species, but he ached for it. To give the human babies. Gorgeous, squirmy babies.

[seaweed_writes]

Right now, Sherlock wasn't even thinking about there possibly being any repercussions with this, because not only were they different species, but (as far as Sherlock knew at least) they were both male. So the thought didn't even occur to him.

All he was thinking about was how in the world was he going to do this? He had no idea if he would even fit. He didn't know a think about fishman anatomy, and he'd never been inside a male or a female, so he didn't even have any human anatomy to compare to.

But he figured that he had to try to get at least a couple of fingers inside, since his cock, while not thick at all, was slightly longer than average, so it seemed from seeing men bathe on a ship.

He pressed a second finger up against the hole- whatever it was.

"C-c-an I?" He asked, nervously.

[ihadabadday]

He nodded. "Yes. Please..." the mer shifted and shifted under the ministrations. Oh. It was feeling good. So good. He shifted his fin a bit, whimpering.

He wanted to mate. He wanted to be one with the man. Yes. John groaned. This was so intense.

[seaweed_writes]

The second finger slid in fairly easily, as the hole was just under the water, which mean that there was little friction. He was warm and wet and tight around his two fingers.

"Johnnn." He said, softly. "I.... " He shook his head, he had no idea what to say. He shouldn't be doing this. He knew he shouldn't. What if he didn't fit or if he hurt John?

That was the last thing he wanted to do.

"I.. have no idea if this will work.." He admitted while working his fingers slowly in and out.

[ihadabadday]

He whimpered as he felt that second finger enter him. The blonde relaxed, shivering at the sensations. Oh. Oh goodness. Yes.

"It will. It will." He nodded. He wanted it to fit, John was desperate. The urge to be mated was rising.

[seaweed_writes]

Neither of them really knew if it would, but Sherlock didn't press the point. It was obvious that no matter what, John was going to want him to do this.

There were still so many alarms going off- he hadn't even known him for 24 hours.. he was another man, and he was a fucking fishman, most of all. He has no idea what was going to happen if he did this.. Everything was screaming at him not to.

And yet, he still couldn't make himself stop.

He had been curious about being with another man since before he stepped onto his first ship at 15. Bur he figured that it would never happen. And being a sailor, there was no pressure to find a wife, so at least he didn't have to pretend to like women.

"S-s-should.. I.. umm.. try a third finger?" He asked, really having no idea what he was doing. He had to guess, and go by what John was saying and doing.

[ihadabadday]

"Please." He begged, "Please."

John was trembling and gasping. He arched his back, trying to push back. He needed. He wanted.

"Sherlock..." he gasped. The human had expressed interest in his normal accent. So he was making sure to use it more. More.

[seaweed_writes]

"Okay." He said, softly. He knew that he had to make sure that John kept that part of himself under the water, it was making his fingers slide in and out much easier.

Even with that, three fingers were very tight, and he had to go slow in order to get them inside. He wasn't even sure that he was going to be able to, but that was about as thick as his penis was, so he knew that if he could make this work, he could get inside of John.

He just had no idea how deep he could go..

He was going to find out soon.

[ihadabadday]

He felt like he was floating as those fingers moved in and out of him.

He'd never been mated like this. John had seen the results of his acquaintances matings, their chosen mate swelling with child.

John couldn't begin to figure out how to tell Sherlock he wanted that.

[seaweed_writes]

Sherlock really had no idea what to do, but he could feel that John was starting to loosen up a bit the longer that he did it.

He had no idea how long he was there, gently and slowly pistoning his fingers in and out of John, but when it felt like he wasn't going to get any looser, he pulled the three fingers out.

"Are... you.. still sure you want me to do this?" He asked. "I don't know if I will hurt you, or how deep I can go inside.. I... I.. I've never done this before." He admitted with a sigh. "I don't know what to do . I've just been guessing this whole time. "

[ihadabadday]

"Sherlock. You. Not hurt me." He begged. John could feel the desperation growing in him. He needed to have that penis inside him.

Why did no one ever tell him how desperate he could feel?

John whined and pushed back. "Please."

[seaweed_writes]

"Alright, alright." He said softly. Apparantly when John was aroused, his speech suffered a little. It was kind of adorable, but he said nothing about it.

Instead, he held his cock in his hand, stroking it a few times. This was going to be a bit awkward, because he was part in and part out of the water, but he found that if he kneeled over John, straddling his fin with either leg, sinking into the sand actually helped him get a lower angle, which helped.

"I'm going to go really slow, John. I have no idea what is going to happen." He took a deep breath and steadied his shaking hand. One hand he put on the small of John's back to steady himself. The other was on he base of his length.

He lined up against John and moved around a bit to get a feel for it. Then he pressed in and held for just a moment before he started to push in, oh so terribly slowly.

"Johhhnnnn...."

[ihadabadday]

John tended for a moment when Sherlock started to push in. But all that tension bled out of him and he relaxed.

Oh.

The blonde whimpered. Oh that felt good. So good. Especially for the first mating. People said it could hurt. But there was none of that. Just intense pleasure.

[seaweed_writes]

When Sherlock had pushed the head of his cock through the ring of muscle and inside of John, he paused. He could feel John tense, and then relax, but was still worried so he continued to wait.

"Are.. you.. okay?" He asked hesitantly? He didn't seem to be showing any pain, but he had no idea of the pain threshold of these creatures.

[ihadabadday]

"Yes." He nodded, "okay. Please..."

The blonde tried to push back, to get more of the two finner inside him.

He needed it. Oh how he needed it, was desperate for it.
