After the whole act with Asahi, Grayfia slept for an hour or two. Laying in his arms, her heart felt like it would jump out of her throat. Her cheeks reddened. If she didn't know about a devil's immunity to the diseases, she would've blamed the rising heat on the fever.

The way she acted made her during the sex, the passionate expressions she showed, or her moans whenever he hit her ass, Asahi was sure to tease her about it. ​​

She peered at the said person through squinted eyes. He had his eyes closed as if he was asleep.

(He is not. Just deep in thoughts.)

'Klyscha-sama, I'm sorry. I didn't ever ask your permission to join this family…'

(Why do you need my permission?)

'Umm, you're the main wife.'

Klyscha giggled. (Silly girl. As long as Asahi is happy, everything is good.)

'I didn't meet many gods, but you're the kindest one so far.'

(No need to flatter me. You can call me Klyscha-chan if you want. I'm forever seventeen for my love!)

Grayfia's lips raised. Klyscha's voice was too cute. 'Thank you, Klyscha-sama.'

She expressed her heartfelt gratitude to the goddess and snuggled closer to Asahi. Her maid dress was a mess, so her breasts touched Asahi's arms.

"Hmm… you're awake?"

Grayfia kept her lips shut.

"Guess she is asleep," Asahi said. "I wanted to do it again with my adorable and sexy maid."

Grayfia's cheeks flushed.

"Her butt is still red."

Grayfia felt a hand trailing down her back and gripping her butt. He kneaded and caressed her tingly bottom, making her heart race in his chest.

"So soft."

"S-Stop it…"

She couldn't take more of his teasing. With eyes brimming with tears, she tried to stop him.

Asahi's eyes widened a bit. "Oh, you're awake."

'This man…'

He already knew she was awake but acted like he didn't.

"I can't do it. Not today."

Her crotch felt numb after he filled her countless times. Every little movement sent tiny jolts of current to her body. Another round will degrade her mind further.

'It felt… too good.'

"Ohh," Asahi suddenly raised a surprised voice.

"What happened?"

"I… leveled up."

—x—x—x—

[You have leveled up!]

The girls did it. I initiated a telepathy link with Saeko.

'Saeko, what's going on there?'

"Asahi-kun… nothing special. Monster hunting. We are finished with the 37th floor. Aimi-san wanted to delete every monster in existence, so the floors took more time."

That was so like Aimi.

'Wait. I'm coming over.'

"You don't have to. We have it under control. You should accompany Grayfia more.'

Grayfia nudged me. "I'm fine, really. You should go help them."

She was adamant about sending me off.

'How about you guys return? It's enough for today.'

"Okay, Asahi-kun. We will return after leaving a teleportation sticker at the entrance of 37th."

'Hmm… have fun.'

"Are you going?"

I shook my head and stroked her hair. "They're returning."

"You… you don't have to do this. You were asking a lot, so I was thinking about resting today."

She talked like she had another choice after I fucked her silly. I wasn't planning on pushing her this far, but her reactions just kept boosting my libido.

I pulled her closer and kissed her forehead. She squirmed in embarrassment and gave me a pouted glare.

"My Lord is a sadist."

"..."

—x—x—x—

Yotsuba Mansion.

I had to deny Leme's offer to sleep with her and Yuriko since it was Grayfia's first time. I wanted to pour all of my attention into loving her.

"It's fine. Leme understands!"

I kissed her and dropped her off in her room. Saya peeked out with a pouty face, so I gave some kisses to her and returned to Shizuka.

With her in tow, I knocked at Rini's door.

"It's me. Are you busy?"

"Onii...san?" Rini asked, and I heard a cracking sound from her room. "I can't meet you right now."

"W-What happened, Rini? You can tell me, you know? I'm always here to listen."

"Onii-san, please. You can't see me today," she said in a flat voice. "Please, go."

"Rini-chan, can I come in?"

"Nee-chan, ask Onii-san to go."

"Aa-kun…" Nee-san said and patted my shoulder. "I'll check up on her. Don't worry."

That sound from before might be my heart shattering into pieces. What happened to the sweet little sister who used to follow me around everywhere? Maybe she grew up and doesn't love me anymore.

The rejection from Rini riddled my head with questions.

Confused, I walked back to my room and sat on the bed. A blue window automatically appeared in my vision.

Rini's stats and skills were different from before. There was no comparison between them. She could even give a decent fight to Grayfia right now.

Above all, her affection points increased and the title changed to [Her Beloved Brother]. She doesn't hate me. It made my chest lighter.

(Of course, she doesn't.)

'Klyscha, do you know why she is avoiding me?'

(I… do. I made a promise with Rini-chan to not tell you. She also hates herself for doing this, but… you know I can't say more.)

'I see.'

If it's her decision, then I can only support her as her brother.

'What is the deal with the monster core?'

(You remember the skill orbs you use.)

'So they are from other monsters or beings with monster cores?'

(Correct. Rini already has a small core. But it's too small. In the future, she might be able to copy someone's skill to her core. Depending on her affinity with the skill, the skill will stay with her for a few hours or a lifetime.)

'That's a cheat.'

(My love, you can't say that to others. Your very existence is a cheat…)

'One last question. Why don't I see the affection notifications now?'

(I muted them since they bothered my love a little. I'll show them when you feel like it. Here, see the stats of your latest waifu.)

She was confused about whether to treat me as her master or her husband, or it had a question mark because she treated me as both.

Ah, woman. You can never understand them.
