[Yaoi, Hypnosis]

"Ahaha, you look rather gloom, Robin! Did you not like what I cooked up? I thought you said you wanted to traverse Hel, so I did my very best to make you look like you blended in so they wouldn't bat an eye!"

"I do appreciate what you did, Henry. I really do. But that doesn't mean I wanted to end up on the border of death just to avoid detection. In fact, because you went above and beyond to try and make me blend in, I was on the verge of being recruited! I had to plan around my lacking health just to deal with what you did!"

"Oops! Oh well, I just need to make sure I actually kill you next time and then cast a Hex that keeps you from being controlled. That way, you can strike at the enemy Generals without needing to worry about that scary old hag taking control of you!"

Robin pinched the bridge of his nose as he heard his crazy Plegian friend try to cook up yet another scheme. Sure, he was a very useful Dark Mage that had showed how effective he was in the fight against Grima's forces, but that did not stop Henry from having ideas that bordered on pure madness. In fact, sometimes he wondered if the young man was even worse than the Fel Dragon itself...

Henry just kept giggling like he always did. No matter what he was up against, whether it was the hellfire from Múspell, the infernal colds of Nifl, or deadly chill of Hel, he always managed to keep himself cheerful. Perhaps because of his upbringing knocking a few things loose, but that would not serve as an excuse for the kind of antics he carried out.

"Please refrain from killing anybody that's on our side, Henry. I know you're not joking, I've seen what you do when you joke." Robin said as he slowly rubbed his temples a bit more. He really needed to figure out a way to deal with this young man before it was too late. Otherwise... Well, there was no telling if he'd end up actually killing somebody and then cause them all a bunch of problems. Sure, a lot of their allies were brought from other worlds and a death inside the world of Zenith would just return them to their worlds with no real reprecussions... But that then left them vulnerable to manipulation by the enemy forces. In the end, death would only lead back to more death.

"Awww, but then it wouldn't be fun!" Henry said, before giggling like a little madman as Robin shot him a glare. "Fiiiine, I'll change my methods. Torture's not out of the question, right?" He truly was a difficult person to work with. Even if he meant well, in his own twisted way.

With their little argument seemingly cleared up, Henry started to skip off. He had a lot of plans that he needed to carry out. Mostly involving the various outfits that the nice people from Askr had designed for him. Oh, that Vampire costume was one of his favorites, especially since he had that big coffin that was great for bludgeoning!

Robin watched his ally depart, before a devious little idea started to cook inside his mind. There was one thing that he had managed to achieve by getting dangerously close to true death inside Hel. And that might be the key to permanently taming Henry, especially since he was like a rabid dog that knew no better. If anything was going to work, that was probably it.

"Hold on, Henry." Robin spoke, and his cheery friend turned a full 540 degrees before facing him again. "There's something I'd like you to look at before you leave. I did manage to find something down in Hel, and I thought you'd like it." He said, trying to act like he was completely and utterly harmless. An act that was sure to fail considering Henry was smarter than he looked.

Henry giggled a little more as he listened to Robin. And instead of being wary that he might be getting tricked, he instead wandered right over. "You found something down there? Wow, you were that close to death and you could still pay that much attention. You're really something, Robin!" He laughed. Of course he expected Robin to have something up his sleeve. He had come to expect it. But where was the fun in being cautious? He had already lived far too long to worry about his own health and safety.

While Henry was all giggly as usual, Robin held out his hand ever slightly. And dim purple energy started to flow into the palm of his hand, causing the rest of his body to glow as well. He hadn't changed out of the Hel-flavored raiments after all, so tapping into the power that had been granted to him while he was down there naturally reflected on his body.

As the energy intensified, Henry didn't seem to react. In fact, he started to tilt his head a little. "You said you had found something, Robin? This is just your normal magic, isn't it? What's so special about... this..." Just as he started to let his guard down, his voice started to trail off. Because he felt something tugging away inside him...

And then his eyes opened. Henry, who always kept his eyes shut because he didn't want to look at the world that had once hurt him so much, now stared straight into the whirlpool of energy gathered in the Tactician's hand. He had never felt magic like this before. Nor was he really able to describe how it felt. It was like... It was like his mind itself was being sucked in, just by being in the presence of the one that had cast the spell.

The spell that Robin had cast? It was Nosferatu, one of the spells that Henry was proficient in. But by staying in Hel for an extended period of time with his life close to being snuffed out, he started to understand how exactly Dark Magic could manipulate the body and the mind. Which was why he was able to use it like this. Why he was able to draw Henry's mind in, despite how impossible that should've been.

Honestly, he was surprised that it worked as well as it did. Especially against somebody like Henry. But that just made the fruits of his little labor all the more sweet. To see that young man, who always had a happy or self-secured smile on his face, knowing that he'd find a way to twist a perfectly good plan into some kind of misadventure at the drop of a hat... Seeing him with his eyes completely and utterly focused on the swirl was...

Robin felt a bit of sweat running down the side of his face as he let this situation dwell on his mind. Maybe this was why Grima enjoyed the feeling of control so much. If he could stand to approach the Fel Dragon that had claimed his body, while they were both still in Askr's service... He'd have to try and force the answers out of him. Just so he understand his thoughts a bit more.

"Henry? Do you hear me?" Robin spoke up, trying to see if he had gone overboard with this spell. He just wanted to make sure that he was in a trance. If he had lost a bit more than that, he'd have to put an end to it...

But as the young man with the unusually open eyes nodded, Robin both felt a tinge of relief and his heart pounding hard against his chest. Well, if he had come this far, then there was no reason for him to stop. "Listen closely, Henry. Listen as carefully as you can."

Henry's gaze was completely focused on the swirl of energy in the Tactician's hand, but he could hear him clearly. That voice was booming through his head, in fact. After getting rid of all those thoughts that were keeping him from focusing on the swirl, a voice like that could easily take up so much more space.

"You are a pet. You live to serve your owner. The one who speaks to you now is the one who owns you. You love him above all else. And you wish to please him in any way that you can. No matter what he wants, you'll do it. Even if it embarrasses you. As long as it pleases him, then it's your duty as a pet to do it."

Robin's words were sinking into Henry's mind. Those loud words were burying as deep as they possibly could, making it harder and harder to shake them out. Not that Henry would do anything like that. His owner had given him very broad yet very specific orders. Why should he try to go against them, when he had pulled his mind into that wonderful swirl of life..?

In fact, as Henry listened to those words, he couldn't help but smile a little like he did before. But this time it wasn't because he was happy. No, he was definitely elated to listen to his owner. But it was more a smile birmming with arousal. He wanted to listen to his owner for hours upon hours. He really only needed his voice to feel satisfied, everything else was a bonus.

As Henry stuck out his tongue and kept looking deep into that swirl, panting in delight like a dog, Robin could definitely tell that he had been put under such a powerful trance that... Well, the Dark Mage was leaning into it with all of his heart, showing just how effective it had been. In a way, he was worried that if he turned off the spell, Henry's mind was going to break.

So instead, he did the next best thing. He let the spiraling Nosferatu coalesce until it compressed into a tiny black ball. So small that it could fit with ease inside the palm of his hand. Inside this ball was Henry's conscious mind, something that was still so pliable. But he didn't need to manipulate it much more.

Using Nosferatu for a moment more, the Dark Magic swirled around Henry's neck, almost as if Robin was trying to drain his vitality. Once it suddenly snapped into the shape of a leather collar with a slot for the ball to nestle into, it was clear that it was just another trick that he had learned in Hel. How he learned it was anybody's guess at this point, but if they managed to ask him, they'd probably find a blush and a few nervous words leaving his lips.

Once the coalesced Nosferatu ball slotted into the collar, Henry's eyes suddenly snapped shut as he regained consciousness. It was like he returned to normal, a giggle slipping out from his lips as always. It really did seem like nothing had happened, despite how Robin had managed to swirl his mind into obedience.

"Hello, Master!" Only for Henry to break that illusion. Because he understood exactly who was standing in front of him. It was his owner. And thanks to the trance still swirling around inside his head thanks to his mind being stored inside his collar, it was impossible for him to want to fight against his programming. "What would you like to do? You want me to kill anybody that's getting in your way? I know a lot of neat ways to get rid of people, you just need to tell me and I'll get right to it!"

Robin was this close to slapping his new pet because he was back to his old tricks despite the trance. But instead he decided to do something else. "Henry." He said, with the young man snapping to attention once he heard his name. "Stand still for a moment, will you?" He needed to try something out, to see if he could control him more through some... Physical affection.

"Okay, Master!" Henry giggled, standing perfectly still as ordered. Even though one couldn't see his eyes, you could feel the energy and how it tugged at his mind. So much so that his irises, swirling behind his eyelids, were ever so slightly projected in front of his face thanks to the Dark Magic controlling him.

That firm posture and obedient stance was put to the test as Robin, rather dominantly considering his habit of staying in the back and controlling the pace from a distance, grabbed ahold of his crotch and squeezed ever so tightly. Not enough to cause any pain, but enough to force a moan from the pet's lips.

"Whenever you feel this pleasure." Robin's voice took on a more commanding tone, causing the ball in the pet's collar to shine as another element was added to his trance. "You are to snap to attention. You are to completely and immediately drop whatever you're doing. And you are to wait for further instruction. It doesn't matter if you're in the middle of a fight. It doesn't matter if you're planning another awful prank. As soon as you feel this..." He continued to give commands, all while squeezing through the Dark Mage's clothes and stimulating his bulge once more. "You will be a Good Pet. And you will wait for orders."

Henry rapidly nodded as he did exactly what his owner said. All with his usual smile on his face, like this was all just something that came natural to him. "What would you like me to do, Master?" He asked, calmly and happily waiting for his orders. Just like the Good Pet that he was.

Robin reached up and pet the Dark Mage, ruffling his hair like he would a kitten's fur. "You can return to normal. Just remember that at all times. Then your Master will be pleased." He said, as his hold over the Dark Mage vanished once again. Adding this to his trance was to show that he could control him, even without going through the effort of putting him completely under once again.

"Ahahaha! Well, we're going to have a lot fun then, aren't we, Master?" Henry giggled as he snapped right back to normal once again. And he even started to lean into the petting, letting out a kitten-like mewl. "I didn't know you liked cats, Master. Maybe if you'd like, I could be one! I'd just need a few days, and-"

Henry was snapped right back out of one of his possibly dangerous ideas thanks to a squeeze to his bulge once more, before a snap from his Master's fingers returned him to normal. "Hm? Did you do anything, Master?" In fact, his memories of the last moment seemed to have disappeared completely. Probably because of how quickly he had been snapped in and out of his trance...

Robin rubbed his cheek for a moment, before walking over and taking a seat on a chair. All while spreading his legs. "Henry, how about we play a game?" He didn't know how else to breach the subject. Really, he didn't know how much Henry knew in that regard. But he was going to try and see what the young man could do before he'd try anything else.

"Oh, I know this one. I didn't know you were into that sort of thing, Master!" Henry giggled as he skipped over and almost immediately got down onto his knees when faced with the subtle outline of something nice and hard inside his Master's outfit. It was even drooling a bit, the cum bioluminescent like the rest of his body. "Don't worry, you don't need to say a thing. I know how to play this game, Master!"

Robin raised an eyebrow. He really didn't? Well, he could afford to trust his pet. Especially since he could immediately stop him if something went wrong. He just needed to keep a foot close to that bulge, and-

The Tactician's eyes quickly rolled into the back of his head as he felt the pet's tongue slowly being dragged along the length of his rod. Why did it feel so good? He wasn't prepared for it to feel so good. What exactly had Henry done to his tongue to make it cause him to shoot up in arousal that much?

"Ehehehe, even Master's a bit sensitive." Henry giggled, licking his lips ever slightly as he suddenly opened his eyes. "But it's Master's fault for making me this way. I had to pay Master back." Behind the swirl of dark energy in his eyes was the tiniest glint of something fighting back... Or was it playing along? It was hard to tell with Henry. All that it meant was that he had figured out a way to deal with his current situation, and he intended on paying Robin back...

As Henry dragged his tongue along the length trying to escape the Tactician's outfit, it was like he was being pleasued from every possible direction despite the tiniest bit of the wet muscle making direct contact. And that only grew more intense the longer he drew out this kind of teasing. He was able to get him closer and closer, despite barely doing anything. A sign of just how much the young man had been able to practice doing something this erotic...

In fact, once Henry wrapped his lips around the glans of his Master's cock, Robin was on the verge of cumming right then and there. But none of his seed poured forth. Instead, it was like he had been put under a spell of the Dark Mage's making, Henry just giggling as he looked up at his Master.

Henry just stood back up, and carefully brought his hands down to his rear. Invitingly spreading his cheeks as he beckoned his Master to come and claim him. He'd have to lay claim to his pet directly, to make sure that he could maintain dominance.

With his body trembling... Robin got up, and grabbed Henry by the crotch once more to keep him nice and still. All so he could slip his rod into his pet's hole, and start punishing him for trying to fight back.

...Whether this had all been part of Henry's plan to get fucked by somebody he was close to, or he just played along for long enough to have fun, was hard to figure out. One thing was certain, Robin still had quite a bit to learn before he could truly put him in his place.

For now, their coitus would ring out, as the Master made love to his Pet for the first time. Knowing that it would not be the last.
