"Kill me… Why did I do that?!"

Sona covered her face with her hands as she lay beside Jin on the bed. She was still naked, but Jin had already cleaned the room and their bodies with Water Magic.

"Nya! You're quite wild, aren't you? I don't know if Sitri's heiress is quite a masochist nya! Don't worry, I won't tell anyone!"

"Please don't mention that. That's quite embarrassing."

Both girls had opened up to each other already. Sona found out that Kuroka wasn't as bad and as crazy as the rumor said, and Kuroka found out that Sona was quite a masochist, unlike the rumors that said she was a smart and aloof girl.

As Jin had expected, bonding on the bed was the best way for people to open up to each other.

'I am not wrong.' He nodded satisfiedly as he raised his body. Then, he turned to Sona and decided to ask her something that he had been meaning to ask since the first time.

"Sona." He called out to her. "Have your breasts get bigger? It's not fit in my hand anymore."

Yes. After he had felt it a few times, he noticed that her breasts had gotten bigger each time she did the act with him. Maybe it was because of hormones and the fact that he massaged them for a few hours straight. But it has certainly gotten bigger.

If before she was a B-Cup, then they were already C-Cup, close to D-Cup.

"Don't mention that…" Sona's face flushed red as she looked away from Jin. "My bras certainly didn't fit them anymore… So yes. Thanks to you." She continued.

Jin smiled. He loved hearing his personal cow grow bigger. The bigger the breasts, the more he liked it because it would produce more milk too.

More milk meant more EXP, and having more EXP would make him get stronger faster.

'Good. I now know that doing something like this can make their breasts grow."

"Nya! My growth period has stopped already. Unfortunately, I can't grow bigger nya. I envy you, Sona nya!"

"S-Sona?! Ugh…" Sona was still wary of Kuroka, but it seemed like she wasn't as hostile as before. "To think I would have sex at the same time with an Underworld fugitive…"

"Don't worry about small things nya! I hate Devils, but I don't hate Jin's women! They are all friends to me, so let's get along nya!"

"You hate the Devil, huh?" Jin muttered.

"Yes nya. I would like to tell you my story, but it's time for me to go. I bet Sona has something to tell you too!"

"Ah!"

Kuroka got off the bed as she said that picked up her dress on the floor and wore it while Sona, who forgot her real intention, shouted in surprise as she raised her body.

"I forgot about it because you suddenly undressed me and took me to this room!" She complained to Kuroka, but the cat girl only giggled playfully and opened the window.

"But that was fun, right? Let's do it again sometime nya! Fufufu." Kuroka jumped off the window while shouting. "See you tomorrow, Jin nya! You too, Sona!"

"And there she goes," Jin said as he turned to Sona. Her topless body was exposed, and Jin took a few seconds to appreciate her growing boobs and cute pink nipples before he asked, "So? Why did you visit me this early in the morning?"

"Right… About that…" Sona slowly opened her mouth as she held the blanket and covered her body. "I actually wanted to confirm something, but I guess that was confirmed after you used that strange crest to order me."

"Ah." Jin understood from just those sentences. "You wanted to ask me about my power? You have some suspicion about how I got strong in such a short time, no?" He asked with a small smile.

"Actually, yes. I have some suspicions about it and decided to ignore it as it is your secret, but… A letter came to me yesterday, and I thought I should confront you about it to ask for your decision. But first, I need to ask you this. Did you get stronger by having sex, by any chance? Like, the Senjutsu technique you used from the time you punched Riser. You got that technique from Kuroka earlier, no?"

'This girl is actually smart. I forgot about that because she acted like a small masochist slut each time we met. She almost got my power right.' Jin thought as he chuckled slightly.

But she was wrong. He didn't get stronger by having sex but by drinking milk.

Obviously, drinking the milk often led to having sex, but that was a different way to get power. So he corrected her.

"I don't get stronger by having sex, but by drinking milk. You got that one part wrong."

"As expected!" Sona exclaimed, beaming with a smile. "So my suspicion is correct. Un, this is good. You have a massage technique to make girls squeeze milk, right? Like what you do to me. Because I tried it at home, and I can't produce milk by myself!"

"You can say that." Jin nodded. He always made his fog invisible to the others when he didn't need it as a cover, so he just went with Sona's flow so she could be more confident.

"Good. Then, Jin-kun. As you've known, we Devils don't really care about a harem. As long as you're strong enough, then no one would complain about you having a harem. So, here is my proposal." Sona looked at him with a devilish smile.

"Let's hear it."

It might be something interesting. Each time Sona had that smile, she would always propose something that he liked. So he was expecting a bit more this time.

"A girl sent a letter last night. I said that, no? Here is the thing. She said she wanted to meet you. How about you take her as yours? It will be interesting if you do that."

"Oh?" It was totally unexpected. He thought Sona would be a bit reserved about that, but it seemed like she supported him nonetheless. "Let's meet her then. When will I be able to meet her?"

"As soon as possible. I can even call her today if you want to."

"Then let's do that."
