We're Just So Sexually Compatible, Darling❤
“Ah, ah... mmph...❤”
Only after the sun had risen high into the sky did Lilith finally stop ravishing me.
Because she had creampied me countless times, the semen she had ejaculated inside me dripped stickily down between my thighs.
“Ahaha❤ That was a truly satisfying contract, darling❤ Your pussy is more like a succubus's than a real one. It made me lose my mind and cum so much.”
“Is it... finally over...?”
“Of course❤ Take a look at your lower belly. The Crest of the Contract should be there❤”
Looking down at my lower abdomen just as Lilith said, I saw a pattern engraved there, though I had no idea when it had appeared.
...No matter how I looked at it, it looked less like a contract crest and more like a womb tattoo.

“Does this mean I can use your power now...?”
“Yep. But the structure is designed so that the more regularly you inject mana into me, the stronger my authority becomes.”
Injecting mana... huh.
Seeing Lilith smiling with a rather devious look on her face, a wave of anxiety washed over me.
No matter how I thought about it, there was only one way I could imagine a succubus like Lilith "injecting mana" into me.
“Hey... by injecting mana, do you mean...”
“It's probably exactly what you're thinking, darling❤”
“...Creampies?”
“Correct❤”
...Son of a bitch.
Why are my bad feelings always spot on?
It was already frustrating enough to be transmigrated into a game where a single mistake could trigger a bad ending.
But to think I have to keep getting creampied just to borrow Lilith's power and prevent those bad endings.
I really wished someone would come along and tell me this was all just a dream.
“So... have you set up a plan to oppose Ark?”
“...Yeah. Your power is absolutely essential to fight them.”
As of now, I had secured two of the Sins.
The rest were still young and originally friendly toward humans, so recruiting them shouldn't be too difficult, but...
One of them was going to be incredibly tricky.
The Sin of Sloth.
The Sin of Sloth detested moving to an extreme degree.
True to her title, she was a complete shut-in who found absolutely everything to be a hassle.
Yet, in the game, the Sin of Sloth was described as having caused the greatest damage among all the Sins.
So how did a Sin who found even eating to be a chore leave behind the most destruction?
...Overwhelming power.
It was no exaggeration to say that the Sin of Sloth was the strongest of them all.
In fact, unless Lilith grew to her absolute limit, no other Sin could even hold a candle to the Sin of Sloth.
Although she hadn't fully awakened as a Sin yet... considering her majesty during the boss fight, it was only right to prepare as much as possible.
...Even if she's still young, someone of that caliber could probably kill a person with a single flick of her wrist.
Now that I had completed the contract with Lilith, even if I couldn't subdue her, I should at least be able to protect myself.
I decided to seek out the Sin of Sloth quickly, before she could fully awaken.
“Darling❤ Where are you planning to go now?”
“There's someone I need to find. I plan to head over there as soon as possible.”
“We just made our contract, and you're already looking to see someone else?❤”
Lilith whispered, wrapping her arms tightly around me from behind.
“Why don't you... just look at me instead?”
“Unfortunately, that person will be a crucial asset in defeating Ark. I have to bring her in.”
“Well, that's a shame.”
Lilith let out a soft chuckle and tightened her embrace.
As she pressed her body against mine, I could feel something hard rubbing against my thighs, making my face flush with heat.
“But... keep playing with me, darling❤ We're just so sexually compatible, I love it❤”
Hearing that we were sexually compatible from a succubus of all things.
I was seriously worried about my future.
No matter how I looked at it, it seemed inevitable that I would either die of sexual exhaustion or end up as a succubus's cum dumpster.
“...I do need to get stronger, so I'll keep it in mind.”
“Fufu...❤ I'll be in your care from now on, okay?”
...I really don't know if this contract is going to be okay.
“Sister Raviel.”
When I returned home, Igna came out to greet me.
“Igna. Have you been playing well at home?”
“Yes. The maid sister played with me. Though I was a little lonely without you, Sister Raviel.”
Perhaps she had missed me terribly, as Igna clung tightly to my leg.
Then, she looked at Lilith standing behind me and frowned.
“…But who is that lady?”
Was it because she had grown up in the Arena since she was a child?
Igna seemed highly wary of strangers.
“She's someone close to me. So...”
Since we would be living under the same roof for the time being, I tried to explain it to Igna properly, but...
Lilith wrapped her arms around my neck and spoke with a deep smile on her lips.
“We're lovers. Right, darling?❤”
“Lovers...?”
“Yep❤ People who love each other❤”
At Lilith's words, Igna's expression froze.
The temperature of the surrounding area began to rise.
Heat radiated from Igna's body, and soon the air grew so hot it became difficult to breathe.
Igna's eyes burned as red as the sun.
Realizing that something was going terribly wrong, I quickly corrected Lilith's words.
“We're not lovers! She's my friend! Just a friend!”
“…A friend?”
“Yes, yes. A close friend of mine.”
Only after I corrected myself did the rising heat begin to subside.
“A friend, I see.”
A small smile appeared on Igna's lips.
It seemed Igna was quite jealous.
In the Arena, where people killed and were killed every day, there would have been no one she could trust.
If you found someone you could trust for the first time, anyone would naturally form a deep attachment.
Especially if that person was the one who saved you.
...The problem is that her jealousy is on a world-ending scale.
The fortunate thing was that Igna seemed very favorable toward me.
Once Ark descended, I would have no choice but to utilize the Seven Deadly Sins.
To do that, it was best to build up their affection.
“Anyway, she's not my lover, so you don't have to worry, Igna.”
As I stroked Igna's hair and said this,
Igna nodded slightly and replied shyly.
“Y-Yes... I won't worry.”
“Good. For now... I have some work to do, so how about we go out together later?”
“I'd love to. As long as it's with you, Sister.”
Hearing that we were going out, Igna flashed a bright smile.
It was a pure, innocent smile, one you wouldn't expect from a child destined to become the Sin of Wrath.
It must have been so hard. For this child too...
Killing someone causes extreme stress.
The same went for being constantly aware that someone was trying to kill you.
Yet, a young child had lived in an environment where they had no choice but to kill or be killed every single day...
It would be stranger if she hadn't broken.
...Sometimes, humans seem more like the sins themselves.
I stroked Igna's hair a bit more before pulling my hand away.
“I'm going to go work now. Listen to the maid, okay?”
“Yes. See you later.”
“Sighhhhh...”
When I returned to my office, a mountain of work was waiting for me.
Did the original owner of this body just slack off and play around before I transmigrated?
Upon checking, there was a year's worth of documents piled up that required my personal signature.
“I just want to live like a proper noble lady, doing nothing but eating and playing...”
A sigh escaped my lips naturally.
I was already running around trying to prevent the end of the world.
Why did I have to have so much work piled up on top of that?
I wanted to run away somewhere far, but if I did, the world would probably end, so resting was out of the question.
“…What a life.”
Still, feeling like I would collapse if I only worked, I slumped over my desk for a moment.
*Knock, knock.*
The sound of knocking came from the door.
“Yeah. Come in.”
When the door opened at my permission, what I saw was...
Igna, looking hesitant as if asking if it was really okay to enter.
“…Igna?”
“I came because I wanted to see you for a bit, Sister... Is it okay if I come in?”
“Yeah. You can come in.”
As soon as I gave permission, Igna trotted over and sat on the chair beside me.
“Weren't you busy, Sister? Is it really okay?”
“It's fine. There was so much work that I was just about to take a break anyway.”
“Ah...”
Happy that she could stay by my side, Igna let out a small giggle.
She had looked so scruffy when we first met...
But now, perhaps because the maids had cleaned her up a bit,
she looked much prettier than before.
“Sister. Why are you staring at me like that?”
“Huh? Ah... because you're pretty, Igna. That's why I was looking.”
Unaccustomed to compliments, Igna's face flushed bright red.

“N-No... I'm not pretty at all.”
“Really? Then who is prettier than our Igna?”
When I asked, Igna's lips parted slightly.
Soon, she hung her head low and murmured softly.
“You are... much prettier, Sister.”
A faint blush remained on her cheeks.
