Notes

Meruem discovers the wonderful taste of a man who has practiced Nen for a millennia and decides to keep him.

Netero hadn't entered the fight expecting to win or lose. All he knew was his goal - to kill Meruem before he became even stronger by any means possible.
But out of all of the possibilities he had considered, he'd never thought that Meruem could possibly be strong enough to restrain him within a few seconds and leave him helpless on the ground.
And yet here he was, slumped on the floor, incapable of moving or using his Nen. It seems as if his body was both paralyzed and in a forced state of Zetsu. He only had a second, however, to wonder where Netero had obtained such abilities before his thoughts were overrided be the sudden cold of the ground against his warm skin.
Not only, it appeared, did Meruem have the ability to restrain one as strong as Netero as if it were child's play, but he also seemed capable of stripping him instantly without any harm to his actual body.
"What are you doing?" Netero asked, surprised his mouth was still moving considering how weak the rest of his body felt. Meruem didn't reply, however, and opted instead to flip the older man over onto his back so his muscled front was fully exposed to Meruem's lustful gaze.
"Isaac," he said simply (had Netero told him his name?), "I have consumed several people who, like yourself, have unlocked Nen. However, never before have I seen such a..."
He licked his lips and Netero shivered, and not from the cold.
"Delicious aura." The Chimera King suddenly thrust a hand foward and grasped one of Netero's pectorals, squeezing the firm muscle and letting out soft sounds of pleasure at the same time.
"Are you going to eat me, then?" Netero asked, and tried to calm his heartbeat down. It wouldn't do anyone any good right now to be so afraid of something he had previously known to be possible.
"Yes." He said, his other hand straying to Netero's right nipple and pinching it, forcing a choked moan out of Netero. "I'm going to utterly devour you."
And then, suddenly, his mouth was on Netero's chest, licking the other pectoral every which way as Netero cried out underneath him, his body shuddering slightly under the merciless assault. His hands went to the other pectoral, rubbing the rock-hard muscle and teasing the nipple peaked at the top.
"AH!" Netero cried out as he came, his cock shooting ropes of cum onto abs and chest. Meruem bent down during the orgasm and licked up a small portion in between his two muscled pectorals, and his eyes widened as the taste burst in his mouth - so inextricably coated in delicious, substantial Nen, in addition to its original, delicious taste. Never before had he ever seen nor tasted something as delicious as Netero.
And so, obviously, Meruem went in for more, even as Netero slumped from his orgasm and pure exhaustion set into his weary bones. He moaned helplessly, his muscles straining under whatever spell Meruem had put him under, but to no avail. His body remained stationary as Meruem teased at his muscled front again, licking up all of the come and moaning all the while.
The King's hands, meanwhile, went down to Meruem's leaking cock and grasped it with both hands, making Netero moan loudly and shake his head slightly. "NGH!" He shouted as his cock was fondled by Meruem's inexplicably skilled hands. A thumb rubbed against his underside, while the other spread the come leaking out of his tip around the extremely sensitive head. All the while his pectorals and abs, now covered in a sheen of sweat Meruem seemed set on removing, were teased by his rough tongue, and Meruem's other fingers exploited the most sensitive spots on his cock.
"To-too much..." He whimpered out, but nevertheless he was helpless to actual stop Meruem's assault on his body, and so the only thing he could do was lay there and take the overwhelming pleasure. "Plea-" He was cut off abruptly as Meruem pressed a thumb firmly against his cock head and his back arched as he came for the second time within 10 minutes. This time, however, within a second or two his cock was suddenly covered in a warm heat - Meruem's mouth, as he consumed most of the come coming out of Netero's mouth and attempted to prolong it even further by teasing nipples and cock as Netero orgasmed harder than he thought previously possible.
"Your cum," Meruem said almost reverently once Netero had finished and lay on the ground, a new layer of sweat on his body that Meruem planned on licking off entirely. "I was unaware anything could taste so delicious." The brilliant King's mind was now hard at work devising several different ways he could make the poor old man come as much and as frequently as possible. He would enlist the help of his royal guards and other Chimera Ants, have them tease his body while he took Netero's cock. Every once in a while, if he were bored, he might engage with him in a solitary sex session, not to pull out as much come as possible but instead to observe Netero's gorgeous, muscled body in all of its glory (preferably covered everywhere in both come and sweat at all times). Perhaps he could create a machine that would fuck Netero for him and attach another device to his cock to suck the come out when he and the other Ants were busy.
For now, however, Meruem was content just to tease his body, learn all of the dips and curves of his flawless body and how to best exploit them to get the maximum amount of cum out of him. As he went back down on Netero, his mouth continuing to mercillesly suck his cock as his fingers wandered around his oversensitive front and fondled every possible muscle available to him (Netero himself moaning and shuddering the entire time, occasionally begging Meruem to stop) a thought suddenly occurred to him. Wasn't there a particularly sensitive nerve, in the ass, that would certainly bring Netero to more orgasms?
To test his hypothesis, Meruem left his mouth on Netero's cock (just in the case the old man decided to cum more), but his arms went around muscular legs and pushed a finger up Netero's hole, prodding incessantly until the first ring of defense was gone and Meruem was free to explore the space within Netero for that one nerve that would make him come no mater how tired or exhausted he was.
Suddenly, Meruem's head was pushed up as Netero arched up once again, and the King's mouth was filled with more delicious come (although, to his disappointment, it was a little less than the previous two). He raised his head slightly to grin at Netero and gave a little respite to the exhuasted man, the old man's muscled chest going up and down as he attempted to catch his breath from the orgasm.
"I found it." Meruem said triumphantly, and his finger prodded against the spot once again. Netero screamed, his cock raising to full hardness and his body straining from the overwhelming pleasure. "You're mine now." He whispered against Netero's ear as the old man whimpered, his prostate being teased by a few fingers, the muscular valleys of his upper body touched by Meruem's other hand, and his cock overstimulated by Meruem's mouth and his voracious appetite for come.
Netero would continue to be teased like that for 5 more hours, and would be forced to suffer through 34 more orgasms before Meruem finally decided to give him a break (mostly because he had ran out of come, though). He was brought back to the Ant King's Palace, where, from then on, he was endlessly fucked and teased almost everywhere at all times, his only breaks being either when he ran out of come or was knocked unconscious from the unrelenting pleasure and orgasms Meruem was dead-set on forcing out of him.
Starting at 1:00 A.M., Netero was waken up from a brief slumber by the three royal guards, who forced him to come and collected the delicious white liquid (occasionally giving themselves a taste with the permission of Meruem, though most of the time they were able to find their sustenance in Netero's muscular, delicious body) until 5:00 A.M., when Meruem arrived and went down on Netero's cock and balls for four more hours. Netero usually passed out at this time and so was given a 3 hour break. Then, around 12:00 P.M., other Chimera Ants would arrive along with Meruem and he would be fucked for 6 more hours. He was then plugged into a fucking machine specially designed by Meruem (along with other toys to tease his body to more and more orgasms, including three vibrators intended for his nipples and cock) for 4 hours, where they were then taken off and Netero was allowed to sleep for 3 hours.
Occasionally, humans would visit (it would seem Meruem had made peace with outside nations by using Netero's muscled body as a bargaining chip), mostly important political leaders, and were given from half a day to an entire week (wherein they didn't have to allow Netero to sleep, meaning the poor old man sometimes had to endure week long fuck sessions) to tease and play with Netero's body. Once, all of the Zodiacs visited and played with his body, and since each of them were given a week by themselves to play with them, it amounted to around 3 months of teasing and fucking Netero's muscular body to a seemingly impossible amount of orgasms. The new chairman visited every year as well to play with Netero's body. In other words, there wasn't a time Netero wasn't being fucked, whether by Chimera Ants, the King and his Royal Guardians, their fucking machines and sex toys, or people he had previously considered friends who had seemingly been corrupted by lust and helped the Chimera Ants to pull as many orgasms and forced moans out of him as possible.
