High School DxD: Supreme Harem

"By the way, Akeno, do you know any sexual techniques other than watching AV Videos, Lol?"

"Uh, y-yes. Only the knowledge I've learned from the internet, though."

"I see. Well then, let me teach you the proper naughty things. When you're in front of a dick, it's customary for a woman to undress completely. Come on, don't just stare blankly, and take off your clothes."

"Eh, uh!? Ugh... I understand. It's what you, Sensei, said. It's a student's job to obey."

Despite her precociousness, it seems she lacks knowledge of sexual techniques. In that case, it might be a good idea to instill various knowledge in her, knowledge that is vulgar and focused on men other than himself.

When you put your hand on the cardigan first, it will be thrown off. Taking off the white shirt as it is. However, because of her huge breasts, the bra size doesn't match, and she looks like a micro bikini. A beautiful and large areola can be seen from between the bras, although it has a slightly dull color.

Mitarai puts his hand on her skirt and removes it, revealing black panties that match the bra. The crotch area appears damp, perhaps moistened by excitement.

Now only dressed in a bra and panties, Akeno blushes with embarrassment but silently urges him with her eyes, as if there's still something left for him to undress. He takes a deep breath, gathers his resolve, and discards the bra and panties as well.

First, visible through the gap of her bra, were Akeno's areolas and nipples. Her large breasts were adorned with sizable areolas, which leaned towards a brownish color compared to Rias' beautiful pink areolas. It seemed odd for someone like Rias to have such unique features; typically, brownish areolas would be more common. But would they turn darker if she were to become pregnant?

Mitarai briefly imagined Rias with a swollen belly but quickly pushed the thought away.

It appeared that Akeno had inverted nipples, hiding her breasts that swayed with embarrassment. As his gaze moved downward, he noticed her slender waist and the view of her dripping wet womanhood which was clean and didn't have any pubic hair.

Akeno's pussy was a pure art, a masterpiece you could say, since it has never been touched by any man.

"Hmm... Akeno, you have inverted nipples. It's the first time I've seen them."

"I wonder if I am weird. Because of these nipples, I'm not very comfortable bathing with others of the same sex..."

"No, no, they're magnificent. Just like how everyone has different personalities, nipples come in various shapes and types. But in Akeno's case, they're just inverted nipples. So don't be so down on yourself; you should be proud instead. You have such splendid breasts. They're even bigger than your head, aren't they? It's like a collection of every man's dream packed into one."

"Um... I'm not sure if you're complimenting me or criticizing me, so I'm not sure how to react... But thank you. It gives me a bit of confidence."

Akeno's breasts, equal in size or even larger than Rias', would undoubtedly attract attention regardless of gender. Men would gaze at them with desire, while women would look at them with envy.

"Now, after undressing, let's continue with the etiquette. As I mentioned earlier, when faced with a penis, it's customary for a woman to be completely naked. Do you know what comes next?"

"Um... I'm sorry sensei, I can't think of it."

"Well, it's understandable since it's your first time. But instead of just indulging in fantasies and masturbation, think about how to please a man and try it next time. The correct answer is to kneel. You kneel down, showing gratitude for getting an erection because of you, thanking him. A woman is a man's possession, that's Akeno's role. Well, not everyone can be considered a possession. It's only for those who want to belong to the man, to serve his manhood. Being indiscriminate is not appreciated. So, Akeno, do you want to belong to me? Do you want to serve my cock and become mine?"

"Ahh... yes sensei"

As Mitarai shook his penis, Akeno gracefully assumed a seiza position, lowering her head in a natural motion. With three fingers touching the floor, she directed her head toward the penis in front of her, reminiscent of an old Japanese woman who would do the same to her fiancé.

Her pristine white back was visible. Perhaps due to excitement, nervousness, or embarrassment, tiny droplets of sweat, like pearl beads, appeared on her skin.

Something changed within Akeno when she kneeled down. In terms of temperament, she leaned towards the S side, with qualities of submission. It could be attributed to her inheritance from her mother; after all, blood cannot be denied.

Among devils, whose numbers had decreased due to a past war, a game called the Rating Game emerged as a substitute for physical combat. Comparing their kin to chess pieces, devils engaged in elegant battles, showcasing their prowess to spectators. During Rating Games, Akeno revealed her S side and delighted in tormenting her opponents. Among Rias's servants, she was the most feared.

However, the moment Akeno kneeled before Mitarai, the scale of her S side tipped towards the M side. She instinctively understood that she couldn't win against the male in front of her; it was natural for her to submit to him. While she would require the condition of being limited to him, her submissive nature blossomed.

Without feeling any humiliation, Akeno lowered her head with a natural gesture. Her ponytail brushed against the floor.

"By kneeling, Akeno, you become mine from today. No matter what others say, I have no intention of letting you go, so give up on that idea. Now, let's move on. After kneeling, you kiss the tip of my cock, the cock-head, as a sign of servitude."

"Say, "I will serve you from now on," and put your heart into it."

"I will serve you from now on, sensei… Mmm... kiss"

Akeno's shapely lips touched Mitarai's cock, and the glans twitched, making it slightly difficult for her to kiss, but she dropped her lips multiple times.

"Smack smack" The sound of her lips echoed in the room.

As Akeno gazed at the huge dick with a dazed expression, Mitarai gently caressed her head. The last person to caress her head was her detested father. Since then, she had despised being touched by men.

However, the moment he touched her, a storm of joy surged through Akeno's chest.

Slowly transforming her without her even realizing it. From a virtuous woman to a lewd and promiscuous woman.

Akeno's heart starts changing first, hoping to be favored by her sensei. She followed the man's words without question, filling her heart with loyalty and love, leaving no room for doubt.

The Himejima Akeno of yesterday would have laughed it off. The fact that she, who hated men, now was falling in love. Although it was a slightly twisted love, it was still love, and her heart ached just by looking at Takashi Mitarai.

"Good girl, that's enough with the kiss. Now, press your nose against my dick to remember its smell. Inhale deeply to fill your lungs with its scent. Remember the scent of your master and be able to distinguish it instantly." Says Mitarai in a commanding tone.
