"So tell me human, how do you know my true nature?"

"Well for one, I'm not human." Issei replies to the caramel skinned succubus. Issei had brought the succubus into his apartment, but hidden the magical expansions from her. He had brought her to his bedroom, which was the only one that remained unhidden.

"Pfft, with that pitiful level of magical energy! There's no way you could be anything but human."

Issei rolls his eyes but flares up his magical energy and directs it straight at the succubus. The girl suddenly feels incredibly small under the immense pressure exuding from Issei. "Believe me now!"

"What exactly are you?" Hecate says, backing away slightly from the show of great power as she thinks to herself 'Just who or what is this guy? No mortal has that degree of power.'

"That's a need to know basis, succubus and right now you don't need to know."

His words annoyed her to no end. "Fine if you won't tell me, then I can simply make you!"

"You can certainly try." He says as he releases more magical energy, causing the succubus to falter." Tell you what Succubus, I have a proposition for you! I will tell you what I am if you beat me in a little competition."

The succubus looks at Issei a little bit taken aback by his words." What kind of competition, and what happens if I lose!"

"If you lose you will have to become my servant."

"And why the hell do you think I would agree to bogus ass terms like that?!"

"Simple: because I'm giving you an advantage. The contest will be the one thing your kind is built for, sex. I challenge you to a game of endurance to see who can last longer in bed. "

"Hahahahaha! You must be stupid, do you really think you can beat a succubus at sex? You don't even have half of the sexual knowledge I have. I could pleasure you in ways you couldn't even dream of."

"I see, well I'm pretty knowledgeable about it myself, I don't think I can measure up to your level of expertise but you will still lose, I can promise you that."

"Oh really, well then I accept your challenge! The name is Rusalka Hecate, prepare to scream my name as I rock you world."

The now named Hecate starts by immediately casting a charm spell on Issei. He feels the spell hit him and even though the magic is powerful Issei is unaffected, though he decides to act like he is charmed. "Let's start with your name, boy!"

"Of course Mistress Hecate, the name is Hyoudou Issei." Hecate smirks seeing Issei is under her control.

"Good, now strip down your underwear!"

"As you command, mistress." Issei says playing along with Hecate's charms.

After about a minute, Issei is standing there in his underwear. Hecate takes a moment to admire his well toned muscles. He didn't necessarily have bulging muscles, but she could see the clear effects of working out. She also noticed the growing tent in his boxers. "So much for all of that powerful aura, you had me scared for a minute. But in the end all men are the same, nothing but creatures that they give into their baser instincts in the presence of one such as myself."

Seeing his body the dark skinned succubus licks her lips. She slowly slides straps of her dress down, before dropping it to the floor. Issei stares at her beautiful body, she had gone commando under her dress. The dark color of her nipples perfectly contrasted her bronze colored skin. Issei felt like breaking character and jumping her right then and there, but he resisted the urge.

Hecate sits down on the edge of the bed. "It's time to pleasure your mistress, get down on your knees and lick!"

"Yes Mistress," Issei says, complying with the demands of the succubus. He gets down on his knees and sits directly in front of her. The sight of her dripping pussy was a beautiful thing. The smell, the way her juices glistened in the light as it leaked out was intoxicating.

Issei slowly begins licking at her moist folds making sure to get every drop. The taste of her juices is unlike anything Issei had tasted, sweet as honey with just a slight hint of saltiness. As he licks he hears moans of pleasure escaping from his succubus partner. He takes his tongue and licks her clit, before plunging it in between her lower lips. She moans out as he begins to wiggle his tongue around inside her.

Issei knew tactics that succubus used, and most people were wrong. Mortals always came up with the lie that succubus cum works as a natural aphrodisiac, and that was true to some extent, most humans were wrong on one detail. It wasn't the cum itself, it was the fact that they have the ability to instinctually Infuse their love juices with their own magical aura.

This would result in humans falling even more in love with the creatures of lust, because their cum carried the same aura as their charm magic. The way to counter it was simple: overpower its effects with an even stronger magical aura. Issei could tell that she was not experienced enough to know this. As he moves his tongue around inside of her, he coats it in his own magical aura. His movements slowly overpower her without her knowledge. His hard work on her clit and pussy pays off, as she sprays her juices all of her face.

As Issei moves his face away from her, " I must admit I'm impressed. Most men are not as skilled with their tongue as you are. As a reward for your efforts I will give you a little bit of pleasure. Lay down on the bed now."

As she stands up as Issei nods and climbs onto the bed. He flips over onto his back, as Hecate slowly removes his underwear giving her a view of his fully erect 8 inches. "You're definitely a little bit bigger than average as well. Now as a reward I give you a titjob."

This would be Issei's moment to strike and he knew it. He would let her think she was on the winning side for a few more minutes before turning the tables on her. If she was gonna pleasure him with those massive mounds of flesh he was going to let her.

She slowly climbs on top of the bed and positions herself on top of Issei's

legs. She takes her two large assets and sandwiches Issei's member between them. She begins to move them up and down as he slowly licks the tip of his shaft.

The feeling of her breasts as they rub against his manhood and the skillful nature of her tongue as she moves it around the tip makes Issei feel like he is in heaven. " Okay my little pet," Hecate says, still thinking she's in control. "You must ask your mistress for permission to cum. Let me know when you reach your limit, and I will decide if you can have your sweet release or not. Do you understand?"

"Yes Mistress," Issei says in reply.

"Good boy," Hecate says before putting her lips around the tip of his cock. She swishes her tongue as Issei moans from the pleasure he was feeling.

Issei could feel the pressure building up as Hecate continues to pleasure him. She telepathically sends the words "not yet'' into his brain, giving Issei the signal he needed to take control. He grabs her by the hair and forces her down onto his rod. Her beautiful lime green eyes widen in shock at the sudden defiance Issei was displaying.

He suddenly flares his aura up as he says, "listen you soul sucking leech! I'm in control now and if you're wondering how I broke free of your control, well you were never in control to begin with. I only made you think that you were in control, but in reality I was biding my time, waiting to show you how powerful I truly am! And if you dare to try to bite it, my aura will be the last thing you have to worry about!"

She starts to struggle under Issei's grip as he forces her down his length. She was no stranger to deepthroat, but this was the first time she had been forced into it. The feeling of a man dominating her was not something she was used to, usually she was the one in control.

"Let me tell you a secret about your kind, a secret only the wisest and oldest of you know. Do you know how your seductive power works?" Issei holds Hecate's head in place on his cock. "If you don't know I understand, most succubus don't as they do it purely on instinct. Mostly all mortals fall for your charm because they lack the power to resist your magical aura. Combine that with your otherworldly beauty and mostly all will fall for your charm. Succubi also instinctually imbue their love juices with their magical aura in order to keep their victim under their control. Now, what do you think would happen if a succubus tried to seduce someone with a stronger magical aura?"

Hecate couldn't believe what she was hearing. He had to be leing, but then what other explanation would describe his ability to resist her. She had felt his power and can tell that it was much stronger than her own. Issei stares into her lime green orbs, the look in her eyes showed two things. The first being her fear of his aura, and the second being a look of anger at the fact that she had actually been tricked. He continues speaking at the forces

"You think you're the first succubus that I've overpowered? Your kind are so overconfident in your beauty and magical abilities that it makes you arrogant. As for why I am so powerful, it's because my mother was a devil and my father an angel, I however completely embrace my devil side. But enough about me, it's time to put you in your place."

As he says that he shoots his load into her mouth giving her a taste of not only his cum, but of his magical Aura as well. As his load pumps into her mouth, she feels his magical aura begin to overwhelm her with pleasure. But just as she feels she is about to reach her limit, it suddenly stops. Issei releases his grip from her head allowing her to sit up on the bed. He flares his magical aura, "don't say a word and do as I say. Do you understand succubus?"

She simply nods fearing what he could do to her if she disobeyed him. "Good! Now allow me to get up, then get back onto the bed and get on all fours. Hecate complies knowing what he wants to do, he was gonna take her doggy style. She braces herself for him to stick his in of her pussy, but Issei has other plans.

He gives her ass a good smack, before lining his dick up with her ass. She immediately realizes what he is about to do," wait not there. I've never ha- Aaaaaaaaahhhhhhhhh!"

She screams out as Issei plunges into her virgin asshole. Hecate feels the pain as Issei begins to pump in and out of her ass. The sound of slapping flesh fills the room as slams into her . "I-I've never let anyone take me in this hole before."

"Well get used to having your ass filled, because when you become my servant I'll be using it frequently." Issei replies as he continues to pound her ass.

As much as his assault on her ass hurt, Hecate knew he was right. She knew that she was his whether she liked it or not. She had made a bet with him and it was obvious who the clear victor was. His display of dominance had shown her one thing, he was her destined one. Her mom had always told one day she would find the man she was destined to marry. Her mother also said when she found him, she would just somehow know that she had.

She had been sexually active since she was thirteen, now being 19 shelost track of how many men she had slept with. But this man was something special and she finally understood what her mother ment when she would say "you'll just know. "

"Master I submit, you are clearly the stronger one. So I Rusalka Hecate fully pledge my life, my body, and my soul in service to you."

Issei releases his arua enriched load into her ass, as he conjures one of his pawn pieces. He presses the piece into her back." Then be reborn Rusalka Hecate, as a servant to the house of Hyoudou."
