How about yakuza leader Hanzo getting Merman Mccree as a gift? Something pretty to look at at first, but mccree is too rowdy, all ways trying to show boat and be dominant, so Hanzo pulls him out of his tank with the idea of putting an end to it. 1/2

nsfw-sin:

Maybe it goes as planned or maybe Mccree is a lot strong and hornier than he thought, quickly turning the tables and claiming him instead. Hanzo hating it at first, and then gagging for it as he gets stuffed, scales rubbing against his thighs. 2/2

god im sooo about this… man the second you said showboating i immediately thought “oh is he putting on a mating display”, plus dominance means he was trying to show hanzo he’s a big strong healthy fish who’d make a perfect mate, and typically approaching without a threat display would basically be an agreement. i dont quite know how to write this but im gonna try because i fuckin love this

Hanzo had gotten it as a gift for finally surpassing his father and taking over the clan. It was insanely rare and mind-bogglingly expensive, sure, but it required a whole two-story house to hold. Feeding and keeping it entertained cost what would be an arm and a leg for any normal person, its water had to be filtered so often that the electrical bill gave him wrinkles, but worst of all: whenever he had to show it off to prove he kept the gift or impress rivals, or merely passed by and happened to glance over, the awful thing was fanning its fins at him and swimming in zig-zags and loops. Did it think that would impress him?

Finally, after the umpty-hundredth time of a thunk against the glass forcing him to look over at the usual sight of splayed fins fluttering to and fro, angled to catch the light in the most glaring way, he decided the cocky creature had to go. Stomping away, he grabbed a ladder and a towel-then a utility knife for good measure. Dragging them back was a pain, but he was going to teach this stupid creature its place. And if that failed, there was always the rumor that mermaid flesh grants eternal life…

Jesse, he vaguely recalled the last owner had named him, seemed to be puffing his chest proudly at the sight of the object of his affections climbing up to the lip of the tank to get closer to him. He surged up, just like Hanzo had anticipated, eager to meet his lover halfway. Leaning over the lip, Hanzo managed to get his hand into Jesse’s armpit to haul him out when a powerful surge of Jesse’s tail jammed his shoulder into his chest and knocked him off the ladder, sending him scrabbling for whatever he could grab.

Water surged over his head and into his nose, bubbles flying as he flailed in panic, fingers raking over cool skin in fear. Air suddenly met his face once again, and he coughed and spat until he could breathe. Strong arms set him on the shallow peak of rock jutting from the water in the middle of Jesse’s aquarium, and deft fingers set about baring his body before he could come back to his senses. 

“You-” Hanzo started, cut off by a yelp as Jesse surged between his legs, tail slapping the shallow water playfully. The water was still up to his hips here, but at the peak of the rock he would be all the way out. Jesse seemed to anticipate his thoughts, though, digging his claws in to keep him steady as he slotted their bodies together. Hanzo wriggled and spat a string of curses as he felt the first probes of its cock.

When it found his entrance, Jesse drove in with short bursts, the mercifully gradual taper opening him up bit by bit with each push of his tail through the water. Once he’d gotten halfway he focused on a steady grind of his hips, canting in whatever direction made Hanzo make the sweetest sounds. More and more pushed in as he rocked in place, seating himself inside his mate.

Hanzo garbled a complaint as Jesse set a steady in-out with a swish and flick of his tail. It seemed like all his hard work had really paid off as he watched the normally hard-faced man melt under him, jaw going slack as his hips twitched into each thrust. God, it was such a pretty sight. 

The sensation of smooth, wet scales sliding between his legs was unthinkably foreign, as was the push of slick, tapered cock into his body, but here he was loving both. It let him feel the stretch every time Jesse bottomed out, and the obscenity burned his ears and churned his stomach in the most wonderful way. He couldn’t help himself when he started imagining what his new lover’s cum was going to feel like as it filled him up.

Jesse could feel his climax building from the heavy thrum of hot pleasure into blissful numbness as he buried himself deep and humped close and hard. Relief flooded his brain as he flooded Hanzo’s insides-apparently far more than he expected given his wide eyes and rounded mouth-and his body felt wonderfully empty for the first time in ages. Hanzo looked at him with a face like he might cry-fuck, he’d almost been a bad mate!-so he quickly fisted his strangely blunt cock and squeezed and rubbed until he really was crying-great gulping sobs as white streaked over his stomach and his hole milked the last dregs of cum out of his partner.

Whew…Jesse could already tell that his new mate was going to be a handful.
