The reason Mary and Cecily suddenly visited Alvenheim was surprisingly simple: concern for Arwen. It wasn’t a lie; they genuinely worried about her and came to check on her well-being.

Though they joked about squeezing Isaac dry or making him unable to sleep tonight, the reality was the complete opposite.

Isaac may have a calm and reserved personality on the surface, but when it came down to the "main event," he became an entirely different person.

He was like a beast unleashed, relentless until the one who initiated the seduction was utterly exhausted.

Moreover, Isaac had immense patience, a mischievous streak, and remarkable physical stamina. Combined with his deep sense of consideration, he would always prioritize satisfying his partner before fulfilling his own desires.

The result was nights so pleasurable they bordered on addictive. No matter how often it happened, it never became tiresome.

Doesn’t doing it so much harm the body? There’s no need to worry about that.

Isaac possessed divine power comparable to, if not greater than, that of a cardinal. And the most effective way to transmit both divine energy and a man’s "vital essence" was through intimacy.

This was why women who had been with a man of such caliber often had glowing skin and glossy hair.

Far from harming their bodies, it was the opposite. Mary, Cecily, and Adelia were all reaping the benefits.

Not only had their beauty reached a new peak, but their stamina had also gradually increased. Without that stamina boost, they wouldn’t have been able to endure Isaac’s strength.

In that sense, there was reason to be concerned about Arwen.

Unlike Cecily or Adelia, she wasn’t a warrior but more of a mage, meaning her physical stamina was likely subpar. Nor had she started off in sync with Isaac like Mary had.

Above all, the biggest concern was her petite physique. Though her hips were notably wide in proportion, her small stature made it less significant.

"I warned her to be cautious, so she should be fine, right?"
"There’s holy water. It’s the purest elixir, so even if something happens, it should be okay."
"I wish I’d had something like that back then."
"Well, Isaac was new to it then too."

Mary and Cecily chatted as they waited for permission to enter. Currently, they were in a guest suite within Elodia.

Adelia hadn’t accompanied them, as she was undergoing special training with Hawk. Besides, there wasn’t a need for everyone to come along.

For most people, gaining entry to Elodia would have been impossible. But these two were different.

Mary was publicly declared as Isaac’s fiancée, and Cecily was a princess of Helium.

Of course, being Helium’s princess didn’t automatically grant Cecily access to Elodia. After all, her relationship with Isaac hadn’t yet been officially announced.

But anyone paying attention already knew the truth, and the mere fact that she accompanied Mary was as good as a partial declaration.

Though this visit was unofficial, rumors would inevitably spread, and eventually, Cecily would make her relationship with Isaac public.

"Do you think they’re still asleep after going at it until now?"

As Mary sipped tea during their wait, she made the comment half-jokingly.

And yet, it wasn’t entirely a joke. Even after their first night together, the women often spent days recovering.

Especially in the early days of their relationship, which felt like a honeymoon, they had no regard for day or night.

"I’m not sure. It might be tough for us, but the queen might have it harder. Still, Keir said they haven’t stepped outside except to bathe, so it’s possible."
"I’m jealous. When will I get to enjoy my honeymoon?"
"The one closest to marriage is the one complaining? You’re doing this on purpose, aren’t you?"
"Hehe."

Cecily grumbled enviously, while Mary responded with a delighted laugh. Her mind was currently filled with nothing but rosy thoughts of a future with Isaac.

She imagined herself in a pristine white wedding dress, with Isaac in a sleek black tuxedo waiting for her.

Amid everyone’s blessings, they’d leave for a honeymoon, where their nights would be no less thrilling than their first.

She wasn’t even planning to use contraception; perhaps they’d conceive their first child during that trip. Mary closed her eyes, envisioning a future child.

Originally, she hadn’t been too interested in having children, but after meeting Lily, her thoughts changed. A child with Isaac’s vibrant red hair and golden eyes...

Especially since daughters were said to resemble their fathers 80% of the time. Mary herself had often been told she looked like her father.

'How many children should we have? It’d be nice if they came one after another. Four, like my family, would be perfect. Naming them would be a challenge, though.'

As Mary indulged in her happy daydream, Cecily watched her with a mix of jealousy and envy.

Even though she had half-conceded the position of Isaac’s primary partner after the last shocking revelation, she hadn’t given up entirely.

Sometimes, she would taunt Mary, claiming she might bear Isaac’s child first, even if Mary married him first.

Now that Mary’s imagination had wandered in that direction, Cecily decided to strike with a pointed comment to keep her guard up.

"But what if something unexpected happens?"
"Huh? What do you mean by ‘unexpected’?"

Mary snapped out of her daydream at Cecily’s question. It wasn’t something she could ignore.

Cecily gave a mysterious smile before speaking in her usual sultry tone.

"What if someone else bears Isaac’s child before you?"
"…What?"
"It’s unlikely, of course. But think about it—there are already four women in his life. What if someone forgets contraception?"
"…"

Mary’s eyebrow twitched at Cecily’s provocation. It was a deliberate taunt but also a warning.

Cecily had a point: including Arwen, there were already four women involved with Isaac, and that number could easily grow.

Plus, while Isaac was meticulous as a writer, he was clumsy and absent-minded in other areas.

Wasn’t it possible he might make a mistake when it came to his relationships? That was Cecily’s concern.

"Are you... being greedy?"

Mary’s temper almost flared, but she managed to hold herself together. She decided to clarify Cecily’s intentions first.

The demon woman sitting across from her was just as eager—if not more so—to have Isaac’s child.

For Cecily, Isaac wasn’t just her beloved but also the savior of her entire race.

Although she had stepped back from claiming the primary position, Mary knew she couldn’t let her guard down for even a moment.

"Honestly? I am a little greedy. He’s not just the man I love; he’s also the one who saved my people. I’ve been ready since that moment."

Cecily elegantly brushed her hair back as she spoke, her unwavering love and devotion for Isaac evident in her voice.

Mary twitched slightly at her words, then smirked. Her response was dismissive.

"Hmph. Say what you want, but Isaac’s first will always be me. Got it?"
"Fine, fine. I was only talking about a what-if scenario. You know how unpredictable the world can be."
"…"

Cecily’s voice carried both mischief and genuine concern. Mary couldn’t deny there was a degree of truth in her words.

After all, they lived in a world where danger lurked everywhere, and there were plenty of people who wouldn’t hesitate to resort to extreme measures to achieve their goals.

Mary sighed, shaking off her thoughts as Cecily smirked. They both knew the stakes were high.

Just as their conversation reached a lull, a knock came at the door, signaling it was finally time to meet Isaac and Arwen.

"Let’s go."
"Yeah."

They headed to the chamber, only to be greeted by a scene that left them utterly stunned.

"Mommy! Mommy!"
"…Huh?"
"…What?"
"So many mommies!"

Standing before them was a tiny angelic figure, unmistakably resembling Isaac.

Mary’s mind went blank, processing only one thought.

"What the hell?"

Ariel tilted her head and innocently repeated the word.

"‘What the hell?’ Daddy, what does that mean?"

Isaac could only shiver.
