Deep into the night, while Arthur was sleeping peacefully, Alfred was pondering how to bring up the "favor" he had decided on. He wasn't just going to say, "Hey, how do mermen have sex? Because you owe me a favor and I really want to fuck you."
He would have to bring it up carefully or maybe just set the mood right and then remind him that he owes him a favor. Either way, he'd have to plan it out beforehand in rigorous detail.
This whole "favors" thing was kind of like granting a wish. He wondered if that was how that folklore had gotten started, someone helped out a mermaid, and they got a favor in return. And then over time "favor" turned into "wish." It was a curious thought.
Alfred looked over at the sleeping merman. He still hadn't looked up dolphin physiology, so he really didn't know what to expect if he did manage to *ahem* "sleep" with Arthur. Alfred was to worried he'd wake up Arthur to do any "late night research" on the topic, so he figured he'd just have to cross that bridge when he got to it- AKA "learn on the job."
It was also far too late for Alfred to be worrying about it, so he rolled back over and tried to sleep. It would be a few more hours, but Alfred did finally manage to fall asleep and dream perverted dreams about mermen.
Arthur mumbled quietly in boredom. He had been awake for hours, but Alfred still refused to wake up. He poked lightly at the human's cheek, hoping to awaken him. As long as Arthur was on land, he was more or less dependent on Alfred. When the sleeping human still refused to wake up, Arthur pushed him off the bed violently.
He peered over the edge of the bed to see Alfred slowly begin to stir and rub his eyes wearily. Finally the human's eyes opened to stare back into Arthur's sharp gaze.
"What the hell was that for?" Alfred finally asked.
"I'm hungry. And you wouldn't wake up." Arthur said in a condescending tone. Alfred laughed and pulled himself to his feet.
"Alright, alright. Shall we go to the living slash dining room then?" Alfred said, extending a hand and slightly mimicking Arthur's accent.
Arthur pouted a bit, but he eventually took Alfred's extended hand leading to the latter picking him up and carrying him off to the couch again.
"What do you want for breakfast, then? I've got four kinds of cereal, or I could go out and get some fresh eggs and make an omelet."
"Cereal is fine," Arthur decided. Alfred went to fetch the cereal boxes for Arthur to choose from. Arthur scoffed at the bright boxes containing probably 80% sugar and 20% anything actually substantial. Nonetheless, Arthur selected a cereal- "the one with the pirate"- and Alfred went to pour both of them a bowl. They shared the couch as they ate their breakfast.
"So what do you want to do today?" Alfred asked, "I haven't got anywhere to be, so we can hang out all day if you want."
"W-whatever you want to do is fine," Arthur said blushing, "Besides, I really don't know what we could do without me being seen anyway..."
"I could carry you, and we could go out exploring the coastline; we could go sailing; I could rent a movie and we could watch it here- there's loads of stuff we can do!" Alfred said. 'We could have some hot human on merman action...'
"A movie?"
"Yeah. You know what? I think I'll rent 'The Little Mermaid,' see what you think of that."
"Why do I already have the feeling that I'm going to hate it?"
Alfred laughed. They watched it on the tiny TV in the living room and- surprise, surprise- Arthur hated it. Alfred just laughed as Arthur went on and on about every little detail of it from gullible Ariel to the crazy magic to the whole thing with the tridents. But he didn't say anything about a mermaid falling in love with a human and Alfred seemed quite relieved.
The credits started playing and Arthur's complaining peaked as they had to listen to every annoying song over again. He was so wrapped up in his rant that he didn't notice Alfred slowly becoming nervous as he planned his move.
Arthur wasn't at all expecting Alfred's sudden kiss to silence him completely. His lips pressed firmly into Arthur's in a warm touch. The cold returned to Arthur's skin as Alfred pulled away blushing.
"I think I'll take that favor now." Alfred said, the tent in his pants slowly becoming obvious to Arthur. The merman poked it teasingly with his finger, tracing the shape lightly.
"What, this?" he teased. Alfred looked away in an attempt to hide the growing red on his face, but Arthur wouldn't have it. He reached up and pulled the younger blonde closer to him by his shirt, laying him down beside him on the couch. He rubbed his fingers gently along the underside of Alfred's growing erection through his pants.
"Is this what you'd like me to take care of?" Arthur asked seductively. Alfred nodded. "Now ask me nicely. If you don't ask, then it doesn't count as a favor." Arthur grinned.
"Please... take care of..." Alfred turned his face away again in embarrassment.
"Take care of... this?" Arthur said, poking Alfred's cock playfully.
"Yes... please..."
"How? Like this?" Arthur lightly placed his mouth on the tip, still imprisoned by Alfred's pants.
"Yes... yes, please," Alfred nodded. A playful grin crossed Arthur's face as he began trailing his hands up Alfred's chest- under his shirt- running his thumbs roughly across his nipples. He brought his face back to Alfred's and pressed their lips together again, running his tongue along Alfred's lips. Alfred opened his mouth, but Arthur pulled away teasingly and began to take off Alfred's shirt. He trailed the fabric lightly across Alfred's chest before discarding the garment to the side.
Arthur gently ran his tongue along the young boy's neck- sucking on some of the more sensitive areas. His mouth slowly moved down his chest, his tongue circling his nipples like a shark circling its prey. Finally, his mouth closed around the tiny nub and began sucking vigorously on it.
Alfred made a noise somewhere between a moan and a grunt, but Arthur didn't slow himself. He ran his fingers over the now moistened nub as his mouth continued south. His tongue explored Alfred's bellybutton, enticing a low moan from the latter. Arthur continued to pull at the sensitive skin with his tongue, thoroughly enjoying Alfred's reaction.
Finally Arthur's mouth found its way back to Alfred's caged erection, which at this point was throbbing painfully and soaking Alfred's undergarments with precum. Arthur fiddled with it a bit, placing his mouth here and there, teasing Alfred to his limit. He ran his lips along Alfred's head, occasionally closing his mouth around it entirely- further soaking his clothing. He nipped down on the side causing Alfred to jolt and grunt loudly.
Arthur smiled and pulled his mouth away. He rubbed his hands roughly alongside Alfred's cock, his thumbs sometimes rubbing overtop the throbbing appendage. Each of Alfred's rapid breathes held a quiet moan and he shivered every time Arthur touched him.
Arthur ran his thumb across Alfred's concealed erection one last time before moving to remove his pants. He undid the button and slowly forced the zipper down with his ring finger, pressing against the bulge in Alfred's underwear at the same time. Arthur fully removed the jeans and poked the soaking undergarments playfully.
Alfred let out a gasp and a sigh of relief as Arthur slowly pulled the last shred of clothing and Alfred's erection was finally released. The throbbing member desperately called out for attention, yet Arthur still continued to taunt and tease Alfred. He trailed his fingers along where Alfred's legs connected to his body, teasingly pressing into the sensitive skin. He spent a fair amount of time pulling at and taunting Alfred's legs, zigzagging his fingers along the inside of them.
Finally he brought his hands back up and lay them for the first time on Alfred's naked member. His touch was light as he brought his fingers over it- barely touching the sensitive skin. Alfred moaned and clenched his hands into fists. Arthur finally pressed his hands into the younger one's erection, rubbing his thumbs along its shaft sensually.
He moved his hands up and down, slowly pumping. Alfred's moans were more constant now, his hips bucking up in rhythm with Arthur's hands. Arthur steadied the younger one's hips as he brought his mouth to his member. Arthur's tongue rolled over the base of his shaft, delighting in the texture of Alfred's most sensitive skin. He slowly brought his mouth up the shaft, sucking along the way.
He rolled his tongue back and forth over the tip, pressing his tongue against the slit on the top. His tongue traveled and encircled Alfred's head before Arthur's mouth completely consumed the tip. Keeping his hands firmly on Alfred's hips, he slowly began moving his mouth up and down Alfred's shaft, taking in more and more of it with each motion.
Alfred desperately tried to buck up against the movement, but Arthur held him in place. He began to feel the warmth gather in his stomach and Alfred moaned something that might have been a warning that either wasn't heard or was ignored by Arthur as Alfred shot his seed into Arthur's mouth.
Alfred leaned his head back in relief while Arthur coughed. Alfred panted for a while before falling asleep beneath the merman.
((So there's the first smut-y scene... The first I've ever written, so go easy on me. Okay, well technically I had to re-write this chapter, so technically it's my second... And I also did a smut-y role play once... But other than that, this is it. So, still go easy on me... Anyway, I hope you enjoyed it, there'll be more to come, so yeah...))
