After becoming excited and aroused in her room by the fantasy that she might have been the object of the male students’ fantasies that day, and after finishing her usual routine of dinner and studying, Chika logged into the world of Fantasia World.

"Well... yes, yes. It’s been properly unlocked."

Upon logging in, she landed on the first floor of the Tower of One-on-One Duels. As soon as she arrived, Chika headed to the terminal in the first-floor hall, checked the information displayed on it, and nodded with satisfaction.

This was why she had stayed up late playing the previous day. The previous day’s attempts had resulted in exceeding five successful clears of the Tower of One-on-One Duels, which meant that when taking on a challenge from the challenge menu, it was now possible to have multiple instances of the same monster appear simultaneously.

"I ended up staying up late to do it, but... yeah, it was worth it."

She had just completed the quest for the fourth time around the time she would normally log out, so she had decided to go straight into a fifth attempt to make it a nice round number. As a result, she had been overcome with drowsiness all day, but Chika had no regrets. Furthermore, as a by‑product of those five attempts, the variety of monsters she could fight from the challenge menu had increased dramatically from what she had seen with Shiori. Chika seemed pleased with that aspect as well.

"Well then... I’d like to get started right away, but I’d rather do it with my big sister, so let’s not do that today. So... hmm, I’m getting tired of challenging the Tower of Duels every single day. Maybe I’ll do something different today instead of the usual challenge."

After unlocking the new features yesterday, she had logged out immediately due to sleepiness and fatigue. Chika, who had not yet had a chance to try out the newly unlocked features, was now overcome with curiosity and wanted to give them a go. Having decided to restrain that curiosity until the weekend, when she would play with Shiori, Chika resolved to end her challenge in the Tower of Duels for the day and went outside.

"So, what should I do now... Hmm. There’s no point in thinking about it here, so I guess I’ll head back to town for now."

Leaving the Tower of One-on-One Duels, Chika looked up at the sky and considered her next move. Deciding to return to the city for the time being, she took out a teleportation card and teleported to Middle City. The location was the main street of Middle City.

"For now, I think I’ll check out the quests in the Guild. Or maybe I should do some leveling up, or try to find some kind of event..."

Stepping onto the plaza in front of the fountain, Chika first glanced toward the Guild and began to reconsider her strategy for that day’s gameplay.

"Hmm..."

Chika considered not just the Guild but the entire city, taking a broader perspective and thinking as she moved through the area: quests, searching for erotic events, leveling up, field exploration. She was enjoying playing every day, but the more she played, the more things she could do and the more places she could go. Her interests kept growing day by day, so Chika continued to struggle with deciding what to do.

After thinking for a while, Chika slowly turned her gaze in a particular direction.

"...Come to think of it, I haven’t been to that area recently. Maybe I should go there for the first time in a while... ♡"

Saying this, Chika turned her gaze toward an alleyway that branched off from the main street. At the end of that back alley was a man. This was the place where, shortly after she started playing Fantasia World, the man had raped Chika, brought her to orgasm repeatedly, and then, after subduing her, put a Collar of Obedience on her, turning her into a sex slave who would hand over money to him. At first, she would go there on a whim and get raped. She had not been able to go there much lately. Having decided to go after a long time, Chika immediately stepped into the back alley.

Even though it was daytime, she walked several dozen meters down the dimly lit back alley. Then a man lying down came into Chika’s view.

"... Uh..."

The moment she recognized him, a Collar of Obedience appeared around Chika’s neck and clicked into place. As Chika shivered at the hard sensation, the man, noticing her arrival, sat up.

"Huh...? Oh, it’s you. Heh heh."

"Uh..."

The man saw Chika and, with a lecherous grin, stared at her body from head to toe, his gaze lingering with her every movement. As Chika shivered at his lecherous gaze, the man grinned and extended his hand.

"I’ve been waiting for you. You hadn’t been around lately, so I thought you’d run away... Well, first things first, let’s do the usual. I’d like you to hand over the money."

"...Uh, uh... Please, go ahead..."

Chika trembled at the man’s words and showed signs of hesitation, but it seemed the effect of the Collar of Obedience had been activated. Chika took half of her money from the menu and offered it to him.

"Oh, there’s quite a lot more here than usual today. Was the reason you didn’t come because you were earning money to give to me? That’s great."

"Uh, uhh... uhh..."

Ah... I gave away all the money I saved up... ♡

Recently, Chika had not been actively spending money, so the amount she gave to the man had increased. The man nodded with satisfaction at the large sum, and Chika felt humiliated that half of her hard work had been wiped out in an instant... and she trembled with excitement.

"Now I can eat my fill of delicious food again. Hehehe. Alright. Now, let’s have you serve me as usual. Come on—today you’re the one who’ll undress her."

"Uh... y-yes..."

The man was grinning as he looked at the money he had been given. He quickly put it in his pocket, then sat down on a discarded chair nearby, pointed to his crotch, and commanded Chika. Thanks to the Collar of Obedience, Chika’s body moved instinctively upon receiving the command, and she knelt before the man.

"Well then... I’ll serve you..."

Ahhh... ♡ I’d love to serve someone like this... ♡

Filled with a mixture of humiliation and excitement, Chika reached for the man’s pants and pulled them down, exposing his penis.

"Uh..."

Ahhh... a smelly cock... ♡

It looked as though it had not been washed for days; the penis was dirty and gave off a foul odor. But a monster’s penis could have a stronger smell, and she often saw a penis in a similar state when being raped by NPCs. Although Chika felt disgust and discomfort, she did not show any noticeable reaction. Instead, the smell sent shivers down her spine.

"You haven’t been around lately, so my dick has gotten dirty too. So let’s start by having you clean it with your mouth. Hehe, hehehe."

Looking down at Chika, the man spoke about the state of his penis, then gave the order in a gleeful, mocking tone. At the same time as those words were spoken, his penis began to erect rapidly, becoming stiff and pointing straight up.

"Ah... uh, yes..."

Oh, I have to start by cleaning your dick... ♡ Ah, how frustrating... ♡ How frustrating ♡

Chika was thrilled and excited by the man’s words. She gently brought her mouth closer to the filthy, foul‑smelling, erect penis.
