An Oni's Night

Z was furious, because in a contest she should've won easily, Zachary had ruined things. His incessant fear and whining had prevented the focus necessary to win. He was too scared of ****, despite being in a body where he had no agency, to just shut up for the duration necessary for her to win. Now they both had less BP than they should've had, less power than they should've had and worst of all, she had looked weak in front of Felix, the boy who decided everything.

Hence, she decided she was going to make Zachary suffer by blasting every memory she ever had of agony suffered throughout her training and combat. Every broken bone, tooth, and even the time her eyes were gouged out, with regeneration doing very little to reduce the pain in the moment. A slideshow of suffering that Zachary didn't understand, even when he inflicted it on others, and that he could never learn to withstand, because he lacked the discipline through which to do so. Although perhaps that was the wrong word, as Z had met many a violent brute that was more capable of withstanding pain than this whiny piece of shit lounging around in her head.

While those memories entered her mind, Z chose to take the brief window she had before meeting Felix to work out her frustrations on a punching bag. The steady rhythm of kicks, punches, elbows and knees matched Zachary wails of agony. He tried to apologize, to promise he would behave, but she just ignored him. This boy wouldn't understand, because he was incapable of understanding the idea that if one wanted to inflict pain on others, they had to be willing to take it. She had no tolerance for bullies, because when push came to shove, they revealed themselves to be powerless cowards.

The workout finished with a final, massive roundhouse kick. Z was thrilled to see that these punching bags could withstand the immense **** of her blows as she toweled herself off and ran to meet Felix at the master suite. While on the way there, she decided to give Zachary another lesson, so that he would understand the cost of his fear. All the points in her life where she thought she would die, or was scared of losing someone else, coalesced into a montage that he got to drown in. It wasn't that she lacked fear, but rather channeled it, and understood that if she wanted to live a life of ****, she couldn't let fear control her life. Why couldn't Zachary understand that?

Felix came out to greet her, and she took his hand. Z then pulled Felix much closer to her than he expected, both to demonstrate her strength, and to make sure he heard every word she said.

"Regardless of what else we do tonight, I want you to keep in mind one thing," Z said. "I am not Zachary. Got it?"

She saw Felix nod frantically, as if he wasn't the one in control here. If Z was expected to be part of this man's harem, she would be seeking to take advantage of that, as she had many times before with other men. Unlike Zachary, Felix wasn't a bully, and this meant his fear wasn't irritating for her. Instead, she saw him now as a VIP to protect, something she was very familiar with from her long history as a mercenary bodyguard.

When they got to the mess hall, Z sat him down at the main table, and grabbed two bowls of rice. Each one was given a healthy helping of beef cuts to along with an assortment of vegetables that kept the meal healthy. However, after she put down the bowls, she then grabbed a bowl of mac and cheese... and brisket. Lots of brisket. The last time Z had checked, she had five times the caloric needs of a normal human, and that might have been lowballing it. That also came with higher protein and other nutrient needs, which combined to make her feel like she was starving by the time she got to a meal. While that had many downsides, it did mean she got to pig out in a way the vast, vast majority of people could not, would not be able to.

This was demonstrated by that while Felix took his time eating his rice bowl, Z devoured hers in about a couple minutes from how hungry she was, and then set about stuffing brisket in her mouth. Ever since she discovered the buffet had barbecue, she was a common partaker when not focusing on fried chicken or food that was more on the steakhouse end of refined hunks of meat. She had always been a carnivorous woman, in multiple ways, and this bunker hadn't changed that. Would the other side of the equation come into play as well?

"So tell me," Z said between bites of brisket. "Why do you think Zachary hit his friend?"

"I thought Zachary was in your head with his memories, don't you know?"

"I need to hear what you think it is to potentially correct some..." Z paused to swallow. "Misconceptions."

"At first I thought they hated each other... then I found out later they were close friends, and well, I thought it was some hazing shit." Felix replied.

"You aren't wrong," Z went to pick up some food, "But it's actually even worse."

Z came back with a collection of sausages, steamed broccoli, and a bowl of kernal corn. "The thing is, he was... well, lets be honest here, still is he just can't act on it, more of a piece of shit than you thought. I realize that's hard to believe because of what a jackass he was to you, but it's the truth."

She knew Zachary wouldn't whine now. Oh he'd grumble somewhere in her head, but he'd keep quiet, because he knew he'd get tormented by her memories again if he tried anything.

"...how?" The question from Felix was quiet, but the tone was serious and curious, an important combination.

"He did beat up his best friend for a prank connected to a spinning wheel that was connected to a hazing ritual, that part is true," Z said. "However, what makes it even worse is they didn't even have to do that anymore, as the people who started that stuff were started to getting worried Smith would crack down. Zachary just did it anyway because he wanted to impress the older members of the team. He's the type of fuck whose bad behavior is motivated by their insecure masculinity."

Z got up again as she let Felix think about that. It was time for dessert, and hopefully enough calories that her body wouldn't bother her later about it. She also started thinking about what she was going to do with Felix that night, given her meals. If she wanted to use her ass, she'd have to go through some pretty intensive cleaning that she suspected they didn't have time for, but that was okay. She smiled upon remembering that Zachary was the type of homophobic piece of shit that made prison **** jokes, and she looked forward to how she could torment him with anal sex.

"Hey, catch!" Z tossed Felix an ice cream as she brought back a normal sized bowl of cookies and cream with a generous helping of chocolate syrup.

"Man, this place would be the best if you could leave with food," Z said while she dug into the ice cream with a big spoon. "But maybe it's for the best. You don't want to know what my room back home looks like."

Felix nodded while eating the ice cream bar, unsure how to respond. Z meanwhile continued to just spoon in more ice cream, in a way that'd give a normal human a tummy ache, but for her would just about ensure she didn't get irritated from caloric stuff later.

"Alright, there's some stuff we can't do tonight because I have to prepare a bit." Z kept it vague knowing Felix wasn't ready to hear how she got ready for anal sex. Someone who was a recent virgin almost never was, much less an eighteen year old boy.

That all Felix could do was blush showed her she made the right call. Z stacked up all their plates and utensils, then dumped them off in a nearby, extremely futuristic dishwasher that had a ludicrous level of cleaning ability compared to any appliance she had seen, much less Felix or Zachary in their more technologically backwards era.

"Before we start, some rules." Z said as she got up in Felix's personal space to emphasize how much bigger, stronger, and even taller she was than him.

"One, you will not put your dick in my pussy." Z said this while staring him in the eyes, and holding his chin to make sure he understood. "You may be the master, but that doesn't make you worthy of that. No human is."

"Of course, of course, I..." Felix blubbered out.

"Good boy." Z said while putting a finger on his lips. "Next anything I do for you, I expect you to do for me. For instance, I'll gladly suck your dick but I expect your tongue all over my pussy then, got it?"

Felix blushed a lot but nodded in response. Z pulled him to his feet in response, and put her hands on his shoulders.

"Finally, unlike human women, I am far, far stronger than you," Z said. "I know you're a good boy, so I say it here to emphasize that for your safety, and mine given the contest we're in, you should let me take the lead on things. Got it?"

He nodded, a mixture of terror and embarrassment all over Felix's face. This Z was happy about, because it meant that while he was inexperienced, which could be annoying, he wouldn't do anything without her permission. Some human men were stupid in that regard, but one benefit of this boy's background was that any pride in his masculinity he might have had was long gone by the time she showed up.

"Excellent," Z said. "Now lets get you to the master suite."

Felix was terrified. He knew, on some level, that Vizrokoth would intervene if anything bad happened, but that didn't change he was dealing with an oni. He was so **** to not be on her bad side that he was worried he wouldn't be able to get it up, and that would get her furious with him.

However, when they entered the master suite, everything changed. Once the door closed, Z dropped her gym shorts and underwear in a single motion. What greeted Felix was the most amazing, glorious ass he ever saw in his life, and that quite possibly included porn. He hadn't noticed as much before, but each of her butt cheeks was so large that they jiggled a little with every movement she made, but that didn't mean it was just fat, oh no. Her butt was, from what he could tell, in perfect health, with a mix of muscle and fat along every inch of its length that left it with the perfect balance of firmness and mass to leave him unbelievably hard. Most of all, even better than all of that, was its shape, as this oni had a heart shaped ass that also somehow was so full that it aspects of a bubble butt, the combination putting hentai, much less live action porn, to shame in its proportions.

"Ah, my best feature," Z said in a teasing tone. "Somehow always does overcome the fear you humans have somehow. I wonder why?"

He didn't try to respond, and instead Felix just continued to stare as Z took her shirt off. That revealed his earlier vision of her ass was not an illusion, as the tiny bit he hadn't been able to see was indeed amazing. He remembered some of the porn he watched when his mom wasn't home, some of which featured ass eating, and he now understood, more than ever, why someone would want to do that.

"Alright, I'm just going to stretch..." Z said as she bended over, and took off her bra.

Felix felt like if it wasn't for Vizrokoth's magic, he would've cummed in his pants right there. He walked closer, the fearful part of his brain telling him to behave, while the horny side of his brain was so, so **** to at least touch her ass.

"Alright, get over here," Z said as she stood back up, and let her black hair down. "You're going to help me cum tonight, just like I'm going to help you."

If he had run harder in his life before, Felix couldn't remember at the time as he zipped over to the bed. Before he could do anything, Z grabbed him, pushed him onto the bed, and put her hands on his wrists. It was in that moment he remembered just how much stronger she was than him, but it was also then that he got to look at the rest of Z's body.

He already knew Z was attractive, her ass alone did that, but the rest of her was sexy too. She had various tattoos all over her, many of them depicting ****, or monsters, but some looked like kanji, and other stuff he couldn't quite identify. Most of her body was very muscular, although not in a gross way like bodybuilders, and the tattoos framed her assets. Of course, her breasts, while not quite as good as her ass, were amazing in their own right, and larger than he had realized they were because of how they looked on her frame. The horns on her head, the slightly larger teeth near the front of her mouth, and of course, her blue skin, were all reminders that she was not a human woman. And then there was her pussy, which was larger than any other he had seen, and now felt taboo to even look at because of her earlier warning.

Showed Naked Body to Master: +5 VP

"I see you like what you see, boy." Z whispered. The word boy specifically felt like both a tease and a warning, another reminder that she was the one in control here, not him.

"I am going to take your clothes off, because it's an old habit of mine," Z whispered. "You don't need to know why."

Z chose to just tear Felix's shirt off. She would've done the same to his shorts if she wasn't able to pull them down in a single motion with his underwear, judging by how impatient she was. His dick sprang forth once freed from its fabric confines, and stood straight at attention. For the first time in his new body, he was worried whether he'd be big enough.

"Not bad, especially by human standards." Z said as she crawled down his body.

Saw Master Naked: +5 VP

Felix let out a sigh of relief hearing that, but then wondered what she was doing until... she turned around. Once her ass was facing him, she grabbed his dick, and put it between her buttcheeks. He wasn't penetrating, but was instead in the next best thing as far as he was concerned, as her butt cheeks grabbed his dick.

"Since you can't buttfuck me tonight, or even put your tongue in my ass, I thought I'd give you an assjob." Z declared.

What followed was heavenly for Felix, as Z's ass felt as good as it looked, and she had a lot of experience clearly in using her ass in sex. She had better technique with her butt cheeks than he ever had with his hands, and it made him feel better about it. Before he knew it, he was already screaming, "Cumming!"

Rope after rope of cum landed all over Z's back, to which she just chuckled in response. "I love making you men cum your brains out."

First Assjob: +10 VP

Z got off of him, and then lay down next to him. "I've taken care of you. Now, go down between my legs, and do the service that I know you're capable of."

He didn't need to be told twice as Felix crawled down. However, he hesitated, looking up at her.

"You can stick your tongue in there, and actually really should." Z said while putting a head on Felix's head, and guiding him gently, but firmly, to where he needed to go.

Felix started slow, this time not from a lack of experience but wanting to make sure he did what Z wanted. For her part, Z kept a hand on his head, and gradually encouraged him to get faster. Unlike the others, she didn't mind when his tongue occasionally grazed her clit as he kissed, licked, and sucked all over her pussy.

"Alright, now focus on my clit." Z said as she grabbed Felix's head with both of her hands.

What followed next was exhilarating and terrifying for Felix, as he desperately licked, trying to get her to cum, while Z fucked his face. Her hands kept him from moving, and he was worried she was going to break him in the process of fucking his face. It all came to a head when he heard a groan from Z, which was followed by her letting her grip go on his head, and her cumming in his face so hard that it felt like a localized hurricane.

Cunnilingus from Master: +5 VP

"Good boy, very good boy." Z said while gently stroking Felix's hair.

They both got under the covers at that point. Z grabbed Felix, and held him close, as he realized he had just become the little spoon in their sleeping arrangement.

"Next time I sleep in your bed, you're going to fuck my ass." Z whispered into his ear before they both fell asleep...
