Did You Think I'd Just Overlook This Mating-Optimized Body?
Building the orphanage would take some time, so I left Igna at home.
She was still pure since she hadn’t become a villain yet, and that innocence made her remarkably obedient.
As long as I guaranteed her freedom, there was no chance she would awaken as the Sin of Wrath.
Even so, plenty of worries still weighed on my mind.
The next target—the Sin of Lust—was the hardest to recruit.
Unlike the other villains who hadn’t yet experienced their awakening events, the Sin of Lust had already gone through hers and gained a measure of power.
On top of that, her ability was growth-type.
If I left her alone, she would eventually reach a point where no method could subdue her.
When I played the game, the standard strategy was to deal with the Sin of Lust first. That was why recruiting her to my side as quickly as possible mattered most.
Of course, killing her like I did in the game would have been the easier and more reliable option…
But after a certain point in the game, the final boss appeared.
Ark.
The Evil God of this world, the one who bestowed the authorities of the Seven Deadly Sins upon the villainesses.
From the moment he descended, it was fair to say the game hurtled straight toward a bad ending.
With his arrival, the Seven Deadly Sins grew even stronger and the difficulty spiked dramatically.
The game community claimed that if three or more of the Seven Deadly Sins remained when Ark descended, clearing the game became impossible.
No one had ever actually managed it.
…It really is hopeless.
Unlike the protagonist, who could somehow strengthen their own powers, how was an extra supposed to handle Ark?
It was utterly impossible.
As a veteran player, I could say with confidence that even after maxing out the character and retrying dozens of times, Ark had still been a nightmare.
If I wanted any chance of defeating him after reincarnating as the lowest-tier extra, the only path was to bring all seven of the Seven Deadly Sins to my side.
“I just hope the Sin of Lust comes around…”
I had brought insurance, so I headed straight for the area where she appeared.
Once again, it was a dark back alley.
The difference from the place where I had rescued Igna was the thick stench of drugs and cigarette smoke that hung in the air.
A fitting lair for the hedonistic Sin of Lust.
The smell was so vile I had to pinch my nose as I walked. Soon, strange sounds began drifting into my ears.
“———!!!”
They came from far away, so the words themselves were unclear, but one thing was certain.
Whoever was making that noise was in a very bad situation.
I ran toward the sound and found a person so desiccated they looked like a mummy.
And beside them stood the woman who would one day become the complete Sin of Lust, wearing a thick, satisfied smile.
Lilith Arcana.
A half-demon, half-beast hybrid who inherited the blood of both a succubus and a vampire.
She had originally been created to serve as a living weapon… but she proved too weak for the role and was promptly abandoned by her parents.
Yet her power was growth-type.
The more she feasted on blood and semen, the stronger she became. Eventually she fully awakened as the Sin of Lust and slaughtered every last member of the clan that had cast her aside.
Just like the mummy lying at her feet.
“Oh my, darling❤ You promised to satisfy me. Was that truly all you could manage?❤”
Lilith shoved the mummy from her arms. The dried-out husk struck the ground and shattered into pieces.
“Mmm……❤”
Having lost interest in the broken remains, her golden eyes fixed on me.
“Oh my…❤ You there, darling❤ Did you come all this way because you’re interested in me?”
“…You could say that.”
“Hmm….”
Even though she had not yet fully become a Sin, the pressure she radiated made it hard to breathe.
Perhaps it was because she was the first to begin operating as a villain.
I swallowed dryly, nerves taut, until Lilith spoke again.
“A young lady from some noble house, by the look of you. I wonder why such a person would come looking for me…?”
“I came to form a contract.”
“A contract…”
Lilith’s eyes glittered with interest. A seductive smile played across her lips.
“Darling, do you understand what it means to make a contract with me?”
“Of course I do. I know very well how important contracts are to the bloodline—especially a Blood Oath.”
The smile on Lilith’s lips deepened.
“Did you investigate me, darling?❤ You know so much it’s almost embarrassing❤”
“I need to know exactly what kind of being I’m contracting with.”
“Ahaha, good. Very good❤ Then shall we hear the terms of this contract?”
Fortunately, Lilith seemed to view a contract with me in a positive light.
Had she decided I wasn’t even worth her time, I would have ended up like the mummy whose every bodily fluid had been drained.
“Lilith Arcana. I ask to borrow the power of you, a succubus and bloodkin.”
“Mmm…❤ I can lend you my power… but what do you intend to use it for?”
“I’m going to stop Ark when he descends upon this world later.”
The instant those words left my mouth—
Squeeze!
Lilith’s hand seized me by the nape.
The seductive demeanor from moments ago had vanished. All that remained was the cold, murderous aura unique to her bloodline.
“Do you understand what you just said to me, darling?”
Her grip was so tight I could barely breathe.
But I could not show weakness here.
To form a contract with the monster known as the Sin of Lust, I had to put on at least this much of a performance.
“I know. It means I intend to defy your master.”
“You say that even while knowing full well what it implies?”
“In any case, you don’t truly follow Ark, do you?”
Lilith was an extreme hedonist.
She would abandon her master without hesitation if it meant pursuing her own pleasure—an unpredictable chaos factor.
In some routes, she had even betrayed Ark and sided with the protagonist.
“Wouldn’t it be more entertaining to betray your master and claim the throne for yourself?”
“……”
“Lilith. If you lend me your strength, I’ll make sure you live a far more interesting life than you ever could under him.”
Lilith stared at me for a long moment.
Then she burst out laughing.
“Ah, ahaha❤ How amusing, darling❤ You really do know me too well.”
The hand that had been choking me loosened and fell away.
“Very well. I accept the contract❤”
“Good. Then we should prepare the contract document—”
“No❤ I want to do the contract with you a little differently❤”
In the blink of an eye Lilith moved behind me and pressed her hand against my lower abdomen.
A burning, dizzying sensation flared through my belly.
“Ughhh!!❤”
“I want to take your virginity as payment❤”
“My… virginity?”
“Yes. I want to claim your chastity❤”
Lilith’s sudden declaration left me stunned.
Of course, a succubus could form contracts this way, but… to suddenly demand sex?
“You… want to take my first time…?”
“That’s right❤ Surely you didn’t come seeking my power without that level of resolve?”
“That’s…”
The proposal had been so unexpected that I froze for a moment, but I quickly regained my composure.
It was embarrassing, sure… but it wasn’t with a man.
Since it was with another woman, I told myself there was no need to overthink it.
If this was the price for borrowing the power of the Sin of Lust, it was a bargain.
“…Fine. I permit you to take my purity…”
“Wise choice❤”
Lilith smiled sweetly and gently peeled away my clothes.
My naked body—one I had shown to no one since my possession—was laid bare.
“Hehe…❤ You looked lovely from the outside, but the inside is even more beautiful, darling❤”
“Enough with the compliments. Let’s just get the contract over with…”
“As you wish. Then…❤”
Lilith slipped her hand inside her own underwear.
At almost the same moment—
Creak. Creeeak.
A bizarre sound began to rise.
When I looked down, the sight that met my eyes was something I could scarcely believe even as I stared at it.
Where Lilith’s groin had been empty only moments ago, a cock had grown.
“U-uh…?”
“Why so surprised? I said I would take your virginity. Of course I need to grow a cock, don’t I?❤”
Lilith wrapped her arms around me from behind, holding me tight so I could not escape.
“Th-this wasn’t part of the contract…!”
“Did you really think I’d just overlook this mating-optimized body?”
Squeeze——
“O-ohh❤”
When she pressed down on my lower abdomen, my entire body jolted as though struck by lightning.
At the same time, I felt my underwear grow damp.
“I’ll fulfill our contract all night long, darling❤”
