Chapter 10: Learning from Family 

After finishing my family's lesson, I was left alone with Jung Sahwa again today. By now I've grown accustomed to her revealing cow bikini outfit. I opened the envelope I had received earlier but never opened. 

'Hmm, hopefully nothing too complicated comes out of this.' 

I silently prayed as I took out the contents. Most of it was explanations about the Erotic Management Agency, along with details on the benefits of becoming an official member. Skimming through, I saw things like: 

- Using public restrooms 

- Visiting cafes 

- Visiting animal cafes 

- Using the subway 

- Hunting with 5 or more people 

Except for the last item about hunting, I couldn't understand how these counted as tests. These seemed like normal everyday activities, even without the common sense alteration. But looking at the test items, maybe it won't be as easy as I thought. There could be hidden conditions. 

"Do I need to do these in order?" 

"No, you can do whichever you prefer first." 

The order didn't matter. That means these tests likely aren't connected to each other. If they were related, she probably would have warned me about the order being important. 

'Am I overthinking this?' 

I suddenly wondered why I was worrying so much. I should just try them one by one. 

After all, this is the common sense-altered world. Even if things seem normal on the surface, there's bound to be some erotic twist. Thinking about that, I suddenly felt motivated. 

"Then let's start with the public restroom, since it's simple." 

"Understood. Then please follow me." 

"Ah, right." 

I had been having sex with Seowoo until just recently, so I had forgotten to put on clothes. I was about to go back to my room to get dressed when a question suddenly occurred to me. 

"Ms. Jung Sahwa, can I ask you something?" 

"What is it?" 

"Why do men dress normally, while women dress so revealingly?" 

Women are all dressed in skimpy outfits, but men are dressed the same as before the alteration. I'm fine not wearing revealing clothes, but I wondered if there was a special reason. 

"That was the previous director's preference. He said he didn't want to see men's revealing outfits too." 

"Ah..." 

Even I find it hard to look at. Out of gratitude to the former director who has already passed away, I headed to the public restroom in casual attire. 

It was just an ordinary public park. The public restroom located there was our first destination. From the outside, it looked like a normal, slightly old public restroom. But it seemed well-maintained overall, appearing clean. 

"Do I just go in?" 

"Yes, just use the urinal inside and come out. That's all." 

Jung Sahwa's explanation didn't seem particularly strange. So if I just go in and use the urinal normally, will I pass the first test? Isn't that too easy? 

"Is it okay for the test to be this simple?" 

"Yes. After all, this is just the bronze level test." 

Then I guess I can relax. In game terms, this is like a tutorial. It's checking if I can adapt well to the common sense-altered world. If that's the case, I should accept this challenge, right? There will be mountains of experiences waiting for me as I live in this common sense-altered world from now on. I can't falter just because I can't go to the bathroom alone. 

"Alright, I'll be back soon then." 

"Yes, I'll wait here." 

Jung Sahwa waited outside for the test. I went in alone to take the test. Wouldn't it be a problem if I just went in, spent some time, and came out? I asked Jung Sahwa that, but her reply was: 

"It's fine. I'm certain Mr. Kim Jinwoo isn't the type to just waste time." 

I wonder what makes her so confident. I felt awkward receiving such a high evaluation. Still, wanting to live up to her expectations, I confidently entered the restroom. But the moment I stepped inside, I saw no urinals - just a woman sitting on a wooden platform. 

'What's going on? Did I enter the women's restroom?' 

I checked outside just in case, but there was clearly a blue male symbol on the door. This was definitely the men's restroom. Then why was there a naked woman waiting in the men's restroom? As I cautiously approached, the woman noticed me and spoke in a friendly manner. 

"Hello. Are you here to use the restroom?" 

"Ah, yes." 

"I'm sorry. The other girls are on rotation, so I'm the only one here right now." 

Rotation? I tilted my head at the unexpected word. Looking closely, there were similar wooden platforms lined up beside the one she was sitting on. The curved marks on them looked like buttock imprints. Was I imagining this? 

"Then you're here to urinate, right?" 

"Uh, that's right." 

"Then please come here. Here you go." 

The woman suddenly spread her lips with her fingers. Confused, I just stared at her. She tilted her head and asked: 

"What are you doing? Didn't you come to urinate?" 

"No, I mean yes, but..." 

"Then hurry up and do it. There's a human urinal right here." 

'Human urinal? No way...' 

At that moment, I realized the meaning of the test... and understood why Jung Sahwa had such unwavering faith in me. Public restroom. A restroom placed for anyone to use. In a normal world there should be urinals here, but in the common sense-altered world, human urinals. In other words, women receive urine instead of urinals. How perverted and twisted is this? It's clearly too good to just spend time here. 

"I'm sorry. I was lost in thought for a moment." 

"Oh, is that so?" 

I apologized to the human urinal and immediately lowered my pants to take out my penis. The human urinal looked at my penis with surprised eyes, which boosted my confidence. After all, this is a nationally certified A++ grade penis. As I proudly presented my penis, the human urinal's rough breathing tickled my glans. 

"What's wrong? It's not like you've never seen a penis before." 

"W-well, I've seen normal penises, but never one this big." 

When I stroked my penis with my hand, her gaze followed the movement of the glans. Like a cat eyeing a treat, her eyes wouldn't leave my glans. I moved a bit closer and rubbed my glans against her lips. She started sniffing my penis scent along with rough breathing. 

"Mmm! It smells so good. With this scent, I'd definitely buy it." 

"You like it that much?" 

"Yes! I want to smell it forever!" 

Her words came out without a hint of pretense. It seemed genuine. 

Just then, the human urinal who had been closely examining my penis asked me a question. 

"If it's not rude, could you tell me what grade your penis is?" 

"Well, since you asked." 

I took out my phone and showed her the certification. 

The certificate stating A++ grade. Below it was a clear national certification mark. 

The human urinal's voice trembled at the unexpected grade. 

"Eh, eh, an A++ grade penis?" 

"As you can see, it's A++ grade." 

"An A++ grade penis..." 

When I told her my penis grade, the human urinal's pupils completely dilated. It was the kind of eye dilation you'd see when facing imminent death. She stuck out her tongue and licked her lips, but no matter how hard she tried, she couldn't hide the 1cm difference. If the human urinal's pride hadn't been holding her back, she probably would have been greedily sucking my penis by now. 

I stroked my penis and asked the human urinal, trying to comfort her: 

"Do you want to suck it?" 

"Yes! Please bestow your penis upon this lowly human urinal!" 

To deliberately say such lewd things without being told - the common sense-altered world really is the best! My penis was already rock hard, erect and throbbing. 

"Then let's take care of urinating first." 

"Ah, right. I'm ready anytime, so please go ahead. Here." 

The human urinal spread her lips again. This time I didn't hesitate, and shoved my penis deep into her mouth. It passed her plump tongue and reached her throat. That's when the human urinal started eagerly sucking my penis, as if eating an ice cream cone. 

"Mmm, it's been so long since I've seen an erect penis." 

Slurp! Slurp! Slurp! Slurp! 

It was a blowjob so good it felt like my hips would give out. She bobbed her head back and forth, sucking enthusiastically. When I gently stroked her head, she shook it even more vigorously, sucking as if trying to pull out my penis by the roots. 

I wondered if I could have one of these human urinals at home. Her fellatio skills were top-notch. But no matter how much she sucked, what came out wasn't white semen, but bright yellow urine. 

"Ah, it's coming out now." 

"Slurp slurp." 

Psssshhhhh! 

I released a powerful stream of urine like a pressure washer. Normally a woman would pull away in disgust, but the human urinal gulped down the urine as if this was what she had been waiting for. Unlike urinating normally, having someone suck while I did it gave me a strange pleasure. 

When I finished urinating and pulled out my penis, the human urinal who had soaked the floor with her love juices opened her mouth. 

"Thank you. It's been a while since I've tasted such delicious urine." 

"Then while we're at it, I'd like to ejaculate too." 

"Oh, please release plenty of your semen!" 

It would be a waste to just urinate with such a good mouth-pussy. When I brought my penis back to the human urinal, her tongue came out to greet me first. 

"That's right, start by licking the glans slowly." 

"Slurp. Slurp. Hehe." 

After cleaning my glans thoroughly with her tongue, I grabbed the human urinal's head and shoved it in all at once. 

"Mmph!" 

Slurp! 

Her mouth-pussy was completely filled when I inserted it to the base. Her teeth grazed the base a bit, but I firmly held the human urinal's head regardless. 

"Mmph! Mmm! Mmm!" 

"I'll finish quickly, so hang in there!" 

Slurp! Slurp! Slurp! Slurp! 

I shook my hips roughly. Though she let out pained moans, she sucked hard as if not wanting to let go, her cheeks hollowing. How greedy must she be to want semen on top of urine? I put in even more effort for such a greedy human urinal. 

"Is my penis that delicious? Huh?" 

"Mmm! Mm! Mm!" 

Slurp! Slurp! Slurp! Slurp! 

I couldn't understand what she was saying, but I could tell she was happy. Perhaps the human urinal's efforts were bearing fruit. I was gradually approaching my limit as the feeling of ejaculation rose. 

"I'm going to cum now. Drink it all!" 

"Mmph! Mm! Mm!" 

Spurt! Spurt! Spurt! Spurt! Spurt!... 

I ejaculated deep into her throat. But she couldn't handle the large amount of semen, and it overflowed from her nose and mouth, dripping onto her chest. 

"Hah! I'm sorry. I wanted to drink it all." 

"It's okay. Should I wipe it for you?" 

It would be better if she wiped herself, but unfortunately the human urinal's arms and legs were restrained. She seemed to be tied up to be used properly as a urinal. In that state, she couldn't wipe the semen on her body. 

I brought some tissues to wipe her, and the human urinal cautiously spoke to me. 

"Um, are you going to throw away those tissues?" 

"Yes, for now." 

"If you're going to throw them away, could you put them in my mouth?" 

She wants this? The tissues soaked with semen? I hesitated for a moment, but the human urinal opened her mouth wide, urging me to give them to her. At that sight, I shrugged and stuffed the semen-soaked tissues into her mouth. 

"Mmm~. Thick semen oozes out each time I chew. This is the best taste of my life!" 

'Did she perhaps eat things off the street before?' 

No matter how you look at it, saying semen tastes the best is something I just can't understand. 

But I guess it's fine if she's satisfied. However, seeing her pussy dripping love juices while eating the tissues made me wonder. 

"Can I use your pussy too?" 

"Huh? My pussy too?" 

She reacted as if it was only natural. I was surprised by my own words. To say such things so naturally. Have I completely immersed myself in the common sense-altered world? 

"Y-you want to use my pussy too?" 

"You don't want to?" 

"Of course I do! I humbly request it!" 

The human urinal spread her legs wide. Her pussy was already soaking wet with love juices. Just as I was about to touch it lightly with my fingers, I suddenly remembered this was a public restroom. 

"Are there often people watching from outside too?" 

"No. Usually people take care of it inside. Not many people come to this remote place." 

"Ah." 

"And since it's your first time, please use me comfortably." 

Trusting the human urinal's words, I rubbed between her wet folds and inserted my penis in one go. 

"Ohh! A penis, an A++ grade penis has entered!" 

"The tightness isn't bad." 

I had expected it to be loose, but was surprised by how tight it was. Of course, it can't compare to Seowoo or the gyaru duo, but the three of them had exceptionally good pussies. But the human urinal was about 10% lacking compared to them. 

Looking embarrassed, the human urinal explained with a bitter smile: 

"Actually, most men roughly pound me with dildos." 

"Hmm, I see there are people like that too." 

"There are. But those men are all obsolete now." 

I understood what she meant. Since their dicks don't work, they take out their sexual frustration by roughly using dildos. 

They even use two dildos at once when they ejaculate. Even in a common sense-altered world, this isn't right. I should seriously talk to Jung Sahwa about this later. 

"But there's a good way to tighten it." 

"A good way?" 

"If you choke my neck, it gets tighter." 

Choking during sex? I've never done it before, but it sounds interesting. I nodded and gently wrapped my hands around the human urinal's neck. It did feel a bit tighter. Maybe just the thought of being choked made it tighten? Then what if I actually choked her? 

Suddenly, a wicked desire crept up from a dark corner of my mind. As I gradually applied more pressure to my hands, the tightness increased dramatically. 

"It feels good. You're squeezing so tight!" 

"Keh! Kuh!" 

Did I squeeze too hard? Surprised by the choking sound, I loosened my grip. But the human urinal protested as if asking why I stopped. 

"Why did you let go! It felt so good." 

"R-really?" 

"You can choke even harder if you want. Like you're going to break my neck." 

If that's the case, I won't hold back. I choked her neck with all my strength, and pounded her cervix violently to match. 

"That's right, squeeze tight like a human urinal!" 

"Keh! Kuh!" 

Squelch! Squelch! Squelch! Squelch! 

I pounded her pussy roughly. Love juices had already soaked the restroom floor into a puddle. The restroom was filled with the human urinal's moans. 

At first I thought the tightness was lacking, but after choking her, the pleasure completely surpassed my expectations. 

"Choking definitely makes it tighter." 

"Keh! Kuh! Kii!" 

Squelch! Squelch! Squelch! Squelch! 

Even while struggling, the human urinal flashed a peace sign. What a perverted human urinal. I gave her a thick reward befitting such a pervert. 

"I'm cumming!" 

"Ugiiii! Kuuuu!" 

Spurt! Spurt! Spurt! Spurt! 

I ejaculated forcefully while choking her neck. 

The human urinal's body trembled rhythmically. 

When I finished and let go of her neck, 

As soon as my penis slipped out, 

A bright yellow stream sprayed from between her legs. 

"Hehe... hehehe." 

"She's completely lost it." 

It seems she won't come to her senses for a while. 

Is it okay to leave her like this? 

As I was worrying about that, 

Someone entered the men's restroom. 

"Why is she like this again?" 

"She's unconscious." 

"Hmm, this penis..." 

Three naked women entered, their breasts swaying. 

They glanced at the fallen human urinal, 

Then looked this way with smirks. 

"Looks like it's not enough yet." 

"Any semen left?" 

"An extreme penis I've never seen before. Finally my dream..." 

It seems they are human urinals too. 

Three human urinals leaning against the wall, sticking out their butts. 

I can't just ignore this. 

"Hurry up and spread your pussies, you human urinal sluts."
