Here's my answer for the previous preview:

Morregen: Hm, I just want to point out that our main is a Human, for the succubus bit is a nickname, because she slept with many women. So yeah.

Angron: Here we go again.

Luka ririnki: Jinx, you've just spoken it from my mind.

Thanks for all the feedback of what you think.

Okay, I've received your thought and idea through the PM and reviews. I see many of you want me just to let her have the Annihilation Maker (because Boosted Gear and Divine Dividing are used too much) and add Issei later on to balance the story and to make Sona and Rias on equality terms. But, I bet some of you mainly want to see the OC outdid Issei. Or teach him some sense of how to treat a lady right, not to go ripping off their clothes.

Anyway, here's the new chapter. Enjoy!

00oo00oo00

While I'm preparing tea behind the kitchen counter, Sona-chan puts on a stern expression as she looks through each paper was neatly stacked on the table, solemnly say.

"You are quite something, Hazuki-san. You have won an international mathematical only at age 12, three consecutive gold medals at world archery championships in your high school year, and graduate from the most elite university in England. Even your family company's not larges on a scale of the most influential industry in Japan. It seems likely they're rather renowned in the underworld."

My expression turns grim.

I've resisted commenting on her remarked of mine achievement thus far, but I can keep silent no more when she brought up my family company business. I stride to her with two cups of tea in both hands and put it down with a loud clanked. I hold her level gaze, unsmiling, ask.

"Are you trying to provoke me?"

Even the girl couldn't keep her cool against my ill-temper, she reflexively avoiding my gaze. "M-Maou." As if her fear's controlling her, Sona-chan blurted it out without even meaning it.

"Ahem... Pardon for my rudeness. When it comes to my family, I had some outbursts of sudden uncontrolled anger, and always end up lash out to other involuntary. Sorry to let you witness my ugly side of mine."

I haven't taken a good look at the mirror when I'm enraged. But from Sona-chan's reaction, I can tell my villainess's face horrified her to the core. The same goes for Rias, Raynare, and everyone as well. Does it truly wicked and horrified that much?!

"No, it was partly my fault."

Noticing my distress, Sona-chan soon switched her tone more kindly to me. She always puts on her tough cookie act, hiding her awkward true self. But, that's also why I fond that cute sides of her, make me want to tease her.

"You don't have to. So, what's my role as your servant?"

Setting aside of the unpleasant memories, nothing but leave a bad taste in my mouth, I get to the main point we haven't been able to discuss the other day.

"Perhaps, you also crave for my power, aren't you? Because of it, you're determined to rescue me."

She prompt replies. "It was a coincidence. And if I aspired you to be a member of my household." She then takes out a bright blue chess-piece of pawn, cracking a grin. "I would have resurrected you from the dead and reborn you as a Devil."

"Interesting. So the Evil piece you're holding, it is likewise can reborn other beings into Devil. And there are a total of 15 pieces only, right?"

"Correct. You're a fast learner, Hazuki-san. However, they cannot reincarnate God. The reason why I reached out to you, simply because I want to help and didn't expect you're a Sacred Gear possessor. Furthermore, you should consider being in luck that they're not after your Sacred Gear, while you're defenseless alone for the past three days."

I chuckle of her statement.

Yeah, she will get really mad if she does know one of my ex-mistress happened to be a Fallen Angel, and I slept with her three days ago. I better not telling her, for everyone own good.

Wait a minute...! Did she have a crush on me?

I fixed her with a puzzled look try to find a hint from her composure, unreadable expression.

I know it utterly absurd and ridiculous, even so, that's the only thing sounds plausible I can think from the top of my head. She didn't have to go that far for a stranger she met for the first time. And the other day, she clung onto my arms and gave me a laps pillow. If it is not, then what?

She doesn't interest in my Sacred Gear whatsoever, then what does she gain by doing all of this?

But there no way it is, right?

"Why did you come back? You could have run away long ago."

I can't say, more like she'll creep out if I did. Honestly, I decided to stay here due to my corrupted feeling after Sona-chan and Rias gave me quite an erotic, warm welcome. There's no way I would let this once in a lifetime chance pass-by easily, considering you live under the same roof and be lovey-dovey with a high school girl. It's like a dream come true.

"Well, I don't have any place to stay."

Which is not a false lie, by the way.

"Then why don't you ask one of your mistresses? I'm sure they would gladly help you."

Ouch! That kind of hurt and she didn't need to be so harsh.

"It's... complicated. Ahahaha...!"

"..."

No reply.

Uuuuu... At least, say something.

Sona-chan then hands me paper and a pen to sign a contract between us. I take a quick look at the condition she offered; it sounds reasonable. I will be a freeman after clearing my debts. Except for the stupidly insane amounts of money God-knows-where, four hundred fifty million adding into my previous debt.

"Sona-chan."

"Yes, is there something?"

"Where is this 450 million came from?"

I asked without a tremble in my voice, though inside me, I felt like my bones had turned to jelly after counting the numbers several times.

"You should have better known than anyone else."

"I don't," I said as I gulped air to steady myself.

"It's the money from all the women you slept with."

She's so brutally straightforward that it was literally splitting my heart in half. She does not pull a punch.

Hidden behind the paper in hands, I steal a glance at Sona-chan's face, who is savoring her tea in tranquility, does not bothering to set eyes on me. She is serious about makes me an upstanding citizen from the ground. This girl is a natural-born Sadist, the same as me.

"There's no way I could pay 750 million yen in twenty or thirty years. I would probably have died by then."

Still not bothered to look at me nor answering, only waving the pawn of chess piece slightly.

So if I don't pay up, then my life will belong to her.

It sounds not a bad deal at all. Besides, I have lost motivation to yearn or wish for something meaningful in those three years, nothing but keep holding onto my miserable life, like my dad saved his. But if it is Sona-chan, I don't mind giving my life for her as a returning gift.

Once I sign the contract, its start to emitting blue and white lights within it, from it emerges the symbol, Sona-chan begins to speak in a casual tone; while it was dancing on the air and starts shaping a magic crest on my palm.

"This is the carved seal represents the Sitri. From today onwards, you are the temporary Devil servant into the household of Sona Sitri, daughter of Prince Sitri, an upper-class demon."

"With this, you even know where am I taking a dump, isn't it?"

She nods earnestly, didn't aware of the joke I just made.

"Naturally..."

It finally dawns upon her, she angrily yelling at me in a fluster.

"That was not funny, Hazuki-san. And here I was, being serious about it."

"My bad, my bad."

I'm jokingly smiling, as I contemplate the Sitri family's crest large as a 500 yen coined on my palm.

Did the God of mischievous pay heed to my wish at death's door and granted it? What a thoughtful person he is, for whom he wanted to play a trick on someone.

"Am I your first servant?"

"Second. As for the first, Shinra Tsubaki, her role is a Queen. She's the one who helped me to tender you while you're in an unconsciousness. And she was human; soon you'll meet her. Now then, bend over."

She stands up and gestures me to the table.

"Wh-Why?!"

I can envision her next line is, but pretend not to, hiding my eagerness bubble deep down inside me.

"Disciplining a servant is the master's job! Let's start with a thousand spanks."

I may have a cruelty Sadist side, but most of all, I'm the biggest masochist perverted ever who loves to a cool beauty girl as Sona-chan here gives me a punishment, stepping on me.

"Wait, let me prepare my body and my mind first."

SLAP!

Ignore my pleading she merciless spanked my bottom. It was painful; my body twitches from the sheer ecstasy of it all.

"That is one."

But, I don't think I can persevere it to the fifty counts I'm going to orgasm over and over and over before it could reach to thousand.

I bite down my lower lip and clenching my butthole. As I meditate, fight back my urge to orgasm, Sona-chan continues whacked my rear; it makes a loud thundering whop echo in the still air, pleasing to the ears. Thanks to her, I have reached new heightened enlightenment.

00oo00oo00

'This is bad, isn't it?'

If not because I decided to buy and read a BDSM magazine in the backyard of the old school building in the first place. None of this would happen.

My forehead and my nape got sweaty so much that some might think I just got back from marathon running. But, I bet my clenched hand is getting sweatier and might have already stained it.

'If they found out, my career will be over in an instant.'

In my tracksuit left pocket, I was holding onto the warm and moist panties with my dear life in nervous and afraid I would carelessly let it fall out at any time.

That girl... Himejima Akeno. She's bad news.

DxD

Flashback.

"Hmph... hmph..."

Stood before the full-length mirror, I crane my neck to get a better view at my back then turn to the front with a grimace. Seeing myself in my old simple business suit and skirt I used to wore when I worked at the company, somehow it seems off and no matter how you look at it doesn't fit me at all. When I put it on, it feels suffocating to the point I struggle to breathe properly.

I remove my heavy clothes weighing on my shoulder and slip into something more comfortable.

"Now, I'm good to go."

I off to work, dressing in a dark tracksuit with a backpack carrying heavy books of math teaching materials, slung on one's shoulders; I quickly dashed through the neighborhood to the main street, heading toward Kuoh Academy with ease and breeze as if I'm walking on air.

Well, because starting today I'm a mathematical teacher.

I wonder why I choose an office job in a not particularly noteworthy medium-sized company to begin-with. I must have been crazy back then.

No annoying male bosses. No more irritating ringtone income calls at the desk.

Only girls that are like the fluffy pink sakura blossoms gathered so plentifully surrounding me. Yes, it's like all year round is sakura season.

And today is the 2nd of May. That means hot summer is around the corner, too. Fufufu... I can hardly wait.

2nd of May.

...Oh, shit! I forgot the new issue of Kinbaku mags is out of today.

Don't want to be late to make an impression on the principal on the first day. I hurried to stop by the book store.

"Hazuki Mao-san."

As soon as I stepped out of the door, someone calls out my name, and I turn around to find a young bespectacled-girl long straight black hair, looking at me with her keen eyes.

"Good to see you again, Hazuki Mao. My name is Shinra Tsubaki."

It was the girl Sona-chan briefly mentioned yesterday.

"Pleased to meet you, Tsubaki-san."

I extend my hand with a broad smile; she doesn't move an inch from her spot, just leave me hanging and glare daggers at me.

"Uhm... Tsubaki-san."

She then let out a long sigh, looking down upon me like I'm the worst scum of the entire human being she's ever met.

"Don't call my name so casually like we're friends."

Her tone was frigid and unfriendly match her grim-face. I don't think I've ever done or said anything to make her dislike me. Is she on her period?

"I see you're not running away, whatever your reason is. I won't forgive you if you dare lay a finger on my master, you gigolette. I don't understand why she has to bother to some like you, and I bet reason, why you get killed, is that you're an unfaithful person."

Ack! Her words hit on the mark. What worse is the hatred in her eyes, I have always despised it most reminds me of those kids and their nonsense gibberish back when I was in elementary school.

Damn it! Can't she at least act friendly?

"Take care."

Before she can leave, I stop her track.

"It was nice talking to you too, Shinra Tsubaki. I look forward to working with you."

I put on a big grin and give her bone-crushing greeting, forcibly shaking her hand for a full minute.

I'm going to show her I'm not as worthless as she saw.

00oo00oo00

What a sight!

I stood by the window of the third floor, admiring the girls in their uniform as far as the eyes can see. To wash off the distasteful aftertaste left in my mouth. And among them, I spot a minority of boys as well.

From what I heard, it was a girl's school last year. I assumed after the new principal took charge of the place, he wants to replace the old school system and started it fresh new from scratch, hoping the girls open up more to the males so they won't have trouble afterward.

My only concern is that those boys won't stir any trouble may cause in the future, which only ruins their image and shaming themselves in front of these young ladies from good upbringing families.

And, as a teacher, it's my responsibility to uphold the peace of the school.

Yes, that's right!

After making a vow to myself, I left to the classroom I'm assigned to, in high spirits.

I look up at the sign on the door, class 1-B. Somehow, it reminisces me the time of my youthful naiveté-self, who pursed that pipe dream sooner or later had destroyed by the menacing specter of adulthood. My gaze moves between the pupils out of the window and my own shadow. Whatever their future leads to good or bad, I don't want any of them to end up like me, who aimlessly walking in the darkness.

At the same time, I so envy them.

I slide open the door, greet the classes with a broad smile.

"Good morning. How is everyone doing?"

As I was coming in the front to introduce myself, I already hear their whispers to each other fixated me in curiosity.

"Hey, isn't our new homeroom teacher is a woman?"

"Yeah... I thought she was a guy for a moment."

"Even so, she's kinda hot."

"...and cute."

My face was turning warm, but I pretend I didn't hear anything.

"My name is Hazuki Mao, as of today, I'm your new homeroom teacher. I will be responsible for teaching you all math. Though I am new here, and I hope we can all get along."

I then read aloud their name from the class roster, take their attendance.

"Seat number 1, Sakioka Akane."

"Yes, I love you, sensei!"

It caught me off guard for a sec, but it just a little prank. I ignore it and proceed to address the next one.

"Uhm, Nomura Sachiko."

"I love you, sensei!"

"..."

And just like that, I have no words to say.

The class chuckle, teasingly as I call their name one by one, and they response to me. "I love you." with their cutesy act; anyhow, I manage to survive through it without letting my emotion show on my face.

"Number 21, Himejima Akeno."

The girl tied in a ponytail with a tender smile rose from her seat, gazes me in the eyes.

Whoa..! She's a beauty.

Her attractiveness contrast to Rias's stunning beauty and her fiery crimson-haired, she embodying the principles of the ideal Japanese woman, if you gaze too long at her violet's eyes, you could easily get lost in it.

Ba-thump. Ba-thump. The idea she confesses her love was enough to set my pulse racing. W-Will she say it?

"I love you, Hazuki-sensei."

What...? What was thaaaaat?

"Kyyyyyyaaaaahhhhhh!"

The girl's screeching in high pitches as if they were surprised by Hinejima's words. It goes the same for me, too.

00oo00oo00

I'm exhausted. And that was just homeroom. Getting confessed to by 30 high school girls was a rollercoaster for my nerves. If this becomes a routine every morning, it not sounds so bad at all.

It was the lunch period. I was walking around the campus to find a well-hidden spot I can relax, enjoying my lunch and reading the magazine.

There, I found a vacant building, and no sight of students walking around or go in and out of this haunted empty place.

"This place should do."

Meanwhile, I was losing myself in my world with my back against the wooden walls. "Ara, ara. I didn't know you have this hobby. Sensei." A silvery voice comes from above me broke the silence, as she reaches her delicate fingers to the mag.

The sudden intrusion gives me a real startle; I stumble on my feet turning around, and just to fall flat on the ground again.

"Himejima-san?"

That's right. Eyes that have already baked into my memory, which belonged to a most beautiful face. It was none other than the Yamato Nadeshiko girl from my class. She was leaning out of the window and turn the page with a slight grin, finding the porn mag was amused.

She caught me red-handed in this weirdly embarrassing moment, I know I shouldn't think of it as a teacher, no, as a decent living human being, but I can't help myself getting aroused a bit.

She then shows me a paged of a woman who is hung up and tied down in a bondage posture, whose tits and crotch are being completely exposed, with a look of ecstasy on her face.

"Sensei, which do you prefer? Being tied up or the other way around. You see, I'm a sadomasochist, so I'm fine either way."

Unlike her elegant and gentle nature, the girl front of me seemed so bewitching, more so mature than girls her ages.

"Sensei, want to have an affair with me? In exchange, I'll keep your secret." She said seductively, looking at me with her lust-filled eyes.

Her proposed rattles me. I was at a loss of poise and composure I let out an odd scream.

"Huuuuuuuhhhh?"

I've made a self-promise. I'm going to redeem myself and prove to that obnoxious girl she's wrong. Is this some sort of trial by ordeal God's given me? It must have to be that mischievous God himself.

Calm down, me. I still have a chance to get out of this. All I need to do is take it back.

"How can I trust you won't say a word to anyone?"

She chuckles and gives me a coquettish grin. I think I've just fueled oil on the already burning small flame in her.

What's her request?

Restlessly, I await for Akeno to speak up as she was bending down strip… her panty (?). I can't see because of the wall separating us, and her inexplicit movement makes me think of that way.

"Sensei, give me your hand. It's the item symbolize our friendship."

Despite I reassure myself; I was hesitant to receive the item in her clenched hand, but I can't back down and let her have the advantage here.

"..."

Yes, no need to see I can tell it from the frilly fabric texture in my hand since I'm too familiar with it.

And it freshly warmth too.

I'm not happy at all. I wanted to cry my eyes out so bad.

"You can sniff it if you want to."

"I'm... I'm not going to."

"Fufufu..."

End flashback.

DxD

And throughout the whole day, I was sweating profusely, while running around like a hare just to look out for the girl, worried for her even when I was teaching other classes.

Isn't it supposed to be the other way around?

And symbolize our friendship, my ass.

She's trying to make me looks like a bad guy here.

Even I return her panty in exchange for my mag back after school, how can I sure she would return it for me, and soon tomorrow she'll come to me with more unreasonable requests; in other words, I'm at her mercy.

Uuuuuggghh! I got no choice but to ask Sona-chan's help and brainwash the girl. I would rather be get punished than being her toy.

"Mao."

While I was deep in thought thinking a way out, Rias calls my name in a cheerful voice, poking her head in the faculty room from the sliding door.

"Is there something I can help you with, Gremory-san?"

Looking at the smile of Rias, it calms me down.

"Why are you speaking to me formally?" Rias quizzically asked.

"Here I'm a teacher, so you better address me as Hazuki-sensei."

"Yes, Hazuki-sensei."

She reluctantly replies and walks into the room, but there's someone else with her. As soon as our eyes met, the blood quickly drains from my face.

"Are you okay, Hazuki-sensei? You sweat a lot, and your face doesn't look well."

"Uhm. Rias." I lower my tone to a whisper, asked. "Is she also one of you?"

I steal a glance at Himejima. She greets back with that same annoying amused simper on her face.

"Yes, Himejima Akeno is a Devil."

"Oh my, what a GREAT coincidental."

Indeed. Fate always makes the best arrangements.

I force a smile and give a quick acknowledge nod. Cursing my rotten luck I had. Or to be more exact, to God or Devil himself. *Sob*

I turn my head so that they would not see the tears burning my eyes.

"What do you want?"

"I want you to be our club advisor, the occult research club."

That's unexpected.

She seems to athletic, good at sport no matter which she does. All of the clubrooms, she chooses the ORC but isn't it abolish long ago?

"Don't you suppose to have three more members to become an official club?"

She simply smiles and insists me to sign the paper.

"Don't worry about little detail. I'll take care of everything."

"If you say so. And Himejima-san, I have something to talk to you."

"Yes, sensei."

Doesn't need to look up, I can tell what her expression is and catch the little laugh fufu she did there. She is enjoying it.

00oo00oo00

"Sensei, did you masturbate to my undies?"

"Hell, I'm not."

"But isn't it…"

"That's my sweat."

I cut her off before she could utter another word.

"Hurry up and put it on already."

"Sensei."

She leans forward on tiptoe, pushing her body against mine, and whispered in my ear makes me squirm and feel chills down to my spine.

"If you're too loud, they'll hear us."

The situation I was in so absurd and comical, which only does happen in manga and stuff some might think I made up. I wish I were. But it wasn't.

Right now, we both inside a restroom stall, not in a romantic sense.

You ask how the heck I let it happen in the first place. Well, this girl just happens to be my rival.

"A-Are you done?"

I'm shutting my eyes, timidly asked.

"Sensei, if you kept making that face, there's no way I can hold myself back."

The next instant, I felt a smooth jade hand caresses my hand and slides in between my fingers. The sensations were too much; my knees almost give in.

She then took my hands and placed it on her cool and plump, supple thighs, and I feel her thin waistband undies on my fingers tip. Everything happens so fast my mind began to spinning and whirling oxygen supply to the brain was cut off in a brief moment.

"Please put my panties on for me."

"...Huh!?"

Click!

"Hehe... I was thinking about..."

I hear the soft tread of two pairs of feet and their cheery voice chatting away, they were only three feet away from us. While I was trying to hold in my ragged breathing not to leak out a sound, Himejima faintly murmurs with a sly grin.

"I wonder, what would they think of you if I screamed out for help?"

Her words were like a trigger; it recalls me back this morning.

'You gigolette!'

No need for you to tell, I'm fully aware of that.

'You're an unfaithful person.'

That's right. That's why I was getting killed for it.

And if someone found us, they won't believe in me because I'm a gigolette who would even dare to make a move on my student.

I'm okay with Sona-chan gave me any hellish punishment but growing to hate of me for it.

No, I don't want my only savior to detest me for the rest of her life.

I feel like I get caught in quicksand, the more I struggle, the faster it sucks me down into a bottomless pit.

No, I already have fallen to the very bottom.

Even so, I'll show her who the boss here.

"No matter how many trials you throw at me. Bring it on!"

"S-Sensei? Ah!"

With that determination raging inside my heart, I slide up her undergarment and fix it in place for her in a rough manner. She thought she had me shaken up to the very core; however, she didn't expect it gets me to fire up even more.

And so, the mental battle between us Sadist versus Sadist begins.

00oo00oo00

In the end, she didn't return the mag to me just as I was predicting from the start.

"See you tomorrow, sensei!"

I wave goodbye to her at the corner of the street till I can't see her figure. Then, a familiar voice came from behind me.

"You two seems so close, you and Himejima-san."

She brings it up out of sudden that my spit goes down the wrong pipe, I frantically denied and ran after her while coughing and choking for air.

"N-No, we not."

I don't know where she saw us together, but it best not to bring it up carelessly.

"I am her homeroom teacher, and it's not like we're friends. Hm… What is it?"

She extends her hand toward me and directly commanding me.

"Hold my hand."

I was baffled by her strange behavior I open my mouth wide like an oblivious idiot.

"This is an order." She repeated once more time, but in a demanding tone.

"What if someone from school sees us? And we're not far from school too."

"Then, there's no dinner for you."

"Eeeeeehhhh?!"

I exclaim at her childish-selfish request.

Isn't it unfair to use her authority for that, though?

"One."

"Hold on a minute."

"Two."

Aaahh, god damn it!

I leave with no choice but to take her hand.

Uuuwaaahhh! I'm so nervous my hand is getting sweaty a bit. As I remember, this is not the first time we're holding hands either; at that time, I didn't think much of it. Now, I'm totally aware of how warm and soft her hand in mine. Also, I can't believe she whacked my bottom with these small hands.

We're walking shoulder to shoulder I realize she's a head shorter than me and she looks so vulnerable I can push her down with ease.

But actually, she's a Devil.

Though, I don't know how much of a help as her servant, since I'm a puny human, made from flesh and blood.

I wonder, what is her thought of me inside that little head of her?

The question yesterday still linger in my mind. Even now, I mull over it a little; there's no answer would make sense.

I call on my courage, ask her.

"Sona-chan, did you have a… crush on me?"

"Don't be stupid. I won't date anyone who has a huge wage of debts."

She doesn't have any hesitation and wavering when she speaks aloud of her thought at all. Maybe, I am overthinking.

"Haha, you right. There's no way you would fall in love with an older woman like me who carries a huge loan of debts at all."

As I finish criticism mine flaw, she then interjects, clearing her throat loudly.

"Let me make it clear. I didn't say anything about your age gap."

"...? What do you mean by it, Sona-chan?"

This time, she didn't answer nor look back at me.

"It's red light, let's go."

She had me gripped firmly by the hand and pulling me run across the street at crosswalks. At that moment, I see a flash of light of my future; I once always fantasized appears before my eyes. That is, I marry a high school girl whom I love most, and we're running down the aisle between the pews.

Dear God, is it okay for me to indulge in this daydream a little longer?
