Yuugi's the best person to talk to. She's the only oni you know, and she does seem to be as close to a leader as they get. If she doesn't know anything about the girls, she should at least be able to point you in the right direction. And, hopefully, crack some skulls for you.
Let's see, her house was somewhere on the left side of town, if you remember. You'll just pretend that's the west side; it's not like there's any way for you to tell down here. You walk through the bumpy streets, past the ramshackle houses. The buildings down here are fairly dilapidated, but with plenty of impromptu maintenance that horribly clashes with the original design. They were probably very finely built Japanese homes years before, but the oni's constant brawling has certainly taken its toll on the intended architecture.
A few oni cross your path, but the streets are mostly empty. They don't say or do anything in particular towards you, even though a human down here should be a rare sight. Some are walking opposite you, probably towards that giant pub. Others just sit and rest on their porches. And the occasional oni raping another one, although you think that's consensual by oni standards. It's hard to tell. They're almost all nearly naked, some with just a few scraps of fur or assorted cloth on them, and none seem to prioritize covering their huge tits or large penises. Not that you're complaining.
You find what you believe to be Yuugi’s house after a short walk. The door is open, so you just walk inside. Yuugi is indeed in here, sitting down at a table with a cup of sake in her hand. The smell of cooked food fills the room, so you assume she just finished eating. She notices your footsteps and turns to face you before you can say anything.
“Hmm?! Reimu! Rare to see you down here. Come for a rematch?” she asks noisily.
“Evening,” you guess. “No, I have work to take care of. I need to do some investigating, and I was hoping you could answer some questions.”
“Questions? Hmph. There’s no need for any of that!” she cries out, standing up in a flash and towering over you with her incredible size and bulk. It looks like she really wants that fight, and is getting ready without you. “I’m the cause of everything!” she declares noisily. “Now let’s see how much stronger you’ve gotten!”
“What? No you aren’t, calm down. I already know who the culprit is, and punished her for it. I just need to know how much damage she did, that’s all.” Well, the spider girl was certainly the main culprit, but you might need to include a few oni on the list as well, depending on how things turn out.
“Oh,” Yuugi says plainly, defeated in an instant. “Well, that’s boring. Can we fight when you’re done playing around?”
“Sorry, but I came down here for pleasure. Fighting you would make me too sore to enjoy myself, no matter who won. How about we fuck instead?” you suggest.
“Hmm.” She pauses to think it over. It sounds like she was really hoping to fight you. Dealing with oni is always so tough. “Okay, that’s fine too. So? What did you need?”
Oh good, she’s cooperating. “Well, on my way down here, I got stuck in a spiderweb, and the owner tried to rape me. She said something like ‘I’m going to infect you and watch you be gangraped by the oni.’ It sounds like I wasn’t her first victim, so I need to make sure there aren’t any innocent village girls trapped down here.”
“Hmm. Human girls being gangraped? Sounds kinda familiar. I think I heard about that happening a year ago or something. I didn’t join in, though; most humans are just too boring. That’s all I know. You’ll need to find some of the oni that actually bothered with some weak human girls if you want more than that.”
Well, it’s reassuring that she didn’t take part in this, at least. Now you won’t need to punish her, which would be likely be fun for her and a nightmare for you. And she did confirm that something is indeed going on.
“Thanks, Yuugi. Do you know where I could find any of these oni? Got any names?”
“At the watering hole, probably. I don’t remember any specific people, but that’s the best place to look. Let’s go!”
“…Huh? Are you coming too?”
“Of course! I could use a drink,” she says, then takes a quick sip from the sake bowl in her hand. “Besides, you’re my friend. ‘Course I wanna help you out! With Suika gone, I’m the strongest oni here, so the two of us can force some answers out of anyone!”
“Wait, Suika’s stronger than you?” You always assumed Yuugi was the tougher oni, if only because she’s nearly twice the size of Suika. Either way, it’s rare for her to admit being weaker than anyone else, even another powerful oni.
“Nah. I’m still the strongest, even with Suika around. Gahahahaha!” Oh.
The two of you head outside after that. Yuugi knows the city better than you, so you just follow her. As you thought, she leads you to that large pub you noticed earlier. You could’ve saved the trip and come here directly, but it’s probably better to have Yuugi helping you out.
After the short walk, Yuugi bursts into the pub, filled with purpose. You follow after her, ready to stop her from cracking too many skulls in search of information.
And then she sits down right in front of the bartender.
This is Yuugi, after all. You probably shouldn't be surprised.
“Gimme some of that unpolished stuff from last year. I've been meaning to try that,” she says to the bartender. Then she turns to face you and asks, “Hey Reimu, what do ya want to drink?”
“Shouldn't we be talking to people or something first?”
“Nah,” she dismisses casually. “Drinking comes first, of course! Then we can find out what happened. And then drink again!”
You sigh. You're going to pass on the second round, but having a little drink wouldn't hurt. As long as you clarify on the “little” part, and make certain to get something weak by their standards. They should have some stuff that's perfectly safe for you to drink; the oni do enjoy variation in their alcohol, so they probably prepare a little bit of non-oni alcohol. You walk up to the table and take a seat next to Yuugi.
“Got any human sake?” you ask the waiting bartender. “I'd like a little of that.” The bartender nods and walks back to pick up the drinks.
You take a look around while you're waiting. There are about twenty oni that you can see, although it looks like there's a second floor to the building as well. Most of the oni are more fully clothed than those you saw out on the street, although there's still a couple of bare tits hanging out. That, and there's three pairs of people having sex near the walls. No one else is paying them any mind, so you won't either. Oni customs are weird.
The bartender returns after a minute and drops two boxes of sake onto the counter: a huge crate for Yuugi, and a relatively small box for yourself. It's still more than you'd consider “a little sake,” but it should be manageable. She then pulls out a dish for you to use, and steps away from the two of you.
“Mmm, smells good. Go on, Reimu, drink! Drink!” Yuugi encourages you with a little too much enthusiasm. Well, whatever. A little drink isn't going to hurt anything.
You pour some of the sake into the bowl and take a sip. It's good! The alcohol isn't too strong, thankfully, and it has a nice, dry flavor. Definitely higher quality than most of the stuff you drink at your shrine.
Yuugi fills her dish to the brim and drinks much of it in a single gulp. “Hmm, not bad. It's really rough, but that's good sometimes.” She refills her cup and drinks more at an amazing pace, quickly finishing three quarters of the box. “Alright, time to have some fun!” she announces, grabbing the box with her free hand and walking towards one of the oni in the building. You're almost done, so you pour the tiny bit left into your cup and quickly walk after her.
“Hey, Natch, give us some answers,” Yuugi bellows at her victim. Natch puts down her drink and glares at Yuugi, but Yuugi resumes talking before she can respond. “You know anything about those humans that showed up here 'bout a year ago?”
“I might,” An oni responds while standing up. She glares at you, presumably for being a human. “You accusing me of somethin'?”
You take a good look at the woman Yuugi is agitating for whatever reason. She's a little over a head taller than you; big, but still shorter than Yuugi's ridiculous stature. Her breasts and shoulders are both covered with a brown fur garment, but her midriff is completely exposed. Powerful muscles bulge out from her abs and arms. You can't see her dick under the simple fur pants she's wearing, but her breasts appear to be the same size as yours. Her skin is a dark red and two small but sharp-looking horns jut out of her head, as if there was any question as to her species.
“Yeah, I am. Your dick's the smallest of anyone's in here, and I bet that helps with raping innocent humans. Tell us what you know.”
“You bitch!” Natch cries out and throws a punch at Yuugi. Both of her hands are occupied, so Yuugi simply lifts up a foot and catches the fist with her wooden sandals. The impact makes a loud crack, but Yuugi doesn't budge, not even with only one foot on the ground.
“That's more like it!” Yuugi exclaims, easily overpowering Natch's fist and brushing it downward. She follows that up with a swift kick to the gut, causing her victim to grimace. “But I'm a little busy with my drinks, so feel free to take your anger out on Reimu here. She's the one who wants to know, anyway.”
“What?! Why me?” you complain. Did she forget already that you told her that you didn't come down here to fight?
“Her? That pitiful human?” Natch asks, incredulous.
“Of course,” Yuugi responds to Natch, ignoring you. “Don't take her lightly, though. This 'pitiful human' beat me in a fight two years ago!”
“W-What?!” she yells, completely unable to believe it. Yuugi just grins in response, while you're assuredly looking more and more annoyed by the minute. But you aren't denying Yuugi's claim. “I see. Then, I'll be known as the strongest after defeating you!”
Damn that Yuugi. Is this oni at least going to give you time to prepare? It'll be a problem if she charges at you, and that's exactly what she seems to have in mind. She does look a lot weaker than Yuugi... but you only beat Yuugi because she was holding back. By a lot. At least you remembered to stock up on persuasion needles and ofuda. First, you need to set this sake dish down. Tossing it to the ground would be a waste, as this is really good sake.
“Reimu!” Yuugi declares, grinning like a madwoman, “Defeat her without spilling a single drop of that sake, or you'll have to fight both of us!”
“Don't make me try to show off as much as you do!”
“Quiet!” she retorts. “If you won't fight me, then I'll make you fight others for my amusement. It's only fair.” No it isn't. But Yuugi went and pissed off this oni, so you really don't have any say in the matter. If you don't follow Yuugi's ridiculous rules, she'll join in, and you doubt she'll continue holding back. That would probably be the end of your little vacation.
“Alright, alright. At least let me get out my gohei,” you say, continuing to keep an eye on Natch. It looks like she'll wait that long, at least, and Yuugi hasn't objected. There's no way for you to make use of your ofuda or needles with both hands taken up, but the gohei is definitely the best tool for fighting an oni.
You reach into your shirt and pull out your gohei, holding it up towards your opponent. She stares at you the whole time, watching your movements to know when you're finished getting ready. Not that you're going to attack first. A defensive style is more suitable for this fight. Even if she's weaker than Yuugi, she's still an oni.
The two of you stare at each other for a few seconds, each waiting for the other to move first. You have no intention of making the first strike, so you nod to your opponent to make it perfectly clear that you're ready.
She accepts and throws a punch aimed directly for your face, twisting her hips to put all of her strength into the blow. A quick turn of your wrist places your gohei in front of her fist, and her hand stops in place upon touching the sacred wood. The barrier absorbed the full impact, putting no strain on your body. Good thing, too, as any swift movements would cause your sake to spill. The cup is a little under three-fourths full, so you have some leeway, but not enough.
Natch stares in shock for a solid second, unable to comprehend her powerful punch being stopped so easily. It seems that she's still underestimating you, even after learning of Yuugi's defeat. She recovers quickly and starts throwing out a flurry of punches; first a series of fast jabs from her right, then she starts using her left as well. Each fist comes like lightning and retracts just as fast, but you manage to block them all with quick turns of your gohei. She's aiming to overwhelm you with weaker attacks, since she can't break through with sheer force. But all you need to do is slightly move your wrist to catch her and stop her fists.
After the fourth punch, you lift the sake dish to your mouth and take a big sip. Hopefully drinking while blocking her flurry of attacks looks cool enough for Yuugi to not notice that you're making things easier for yourself in the long run.
She finally takes a break from her attacks, realizing they're not working. The respite only lasts a second, however, and she throws out a weak punch from her left hand. You block it easily, but she places her foot to your left and pivots her entire body towards your open side. Her right fist flies up from below, aiming for your stomach, but you step to the right and turn, then quickly bring your gohei down to slap her arm aside.
The sacred wood strikes her forearm, hitting it with the force of a falling tree. But an oni is still an oni, and the painful strike doesn't deter her for long. Her left comes quickly, aimed for your head, forcing you to duck and take a step away from her. The sake shifts in the bowl but doesn't spill. You were hoping to avoid moving your feet for that exact reason, but it seems your drink was enough to save you.
You think you have a good grasp on her movements now. She's a bit faster than Yuugi, but is indeed a lot weaker. Yuugi was strong enough to break through your gohei's divine barrier, while Natch is only able to force through the weaker paper. If she was a human, you'd be in trouble, but as you're up against the supernatural, you have the upper hand. There's only about a third of a cup of sake left, so you should be able to go on the offensive now.
Natch's fist aims for your head once again, but you intercept it with a quick strike from your gohei. The contact stops her hand, and you take the opportunity to take a quick step towards her. You counterattack, aiming your gohei for the top of her head. As she was thrown off balance by her attack and wasn't expecting you to suddenly go on the offensive, she's unable to stop you. The sacred wood strikes her in the temple, the impact causing her entire body to shudder.
But an oni is still an oni. A single strike of anything isn't enough to bring them down. She wobbles in place for a second, but manages to leap backwards to avoid your followup swing. You could probably lunge to still reach her, but you don't want to risk spilling any of the sake. Instead, you stand still, hoping she'll come after you again.
She doesn't. Instead, she simply circles around you, hoping to find an opening. You follow her while standing in place, turning to watch her. You aren't certain what she's looking for, but she isn't going to find it.
Your patience wears out after she's completed a half circle, and you step towards her to attack. She notices and tries to get the upper hand, but you dodge by quickly stepping to the left. Her arm is extended and a perfect target, so you take the opportunity to punish her and strike her on the bicep with your gohei. She recoils from a mixture of pain and being knocked off balance, giving you more openings. You continue the assault, striking her in the side of her chest, wrist, upper leg, head, and abdomen. Each blow causes her to grunt, leaving her exposed to the next one and completely unable to attack.
She finally collapses after the last strike, bruised from the spiritual energy of your gohei and groaning in pain. Well, she's an oni, so she'll be perfectly fine in a day or two. They do worse to each other all the time. With the fight over, you bring the sake dish to your lips and slowly sip the remaining sake. It seems to all be there, although you'll trust Yuugi to say for certain. You were a bit busy and couldn't pay that much attention to the dish, after all.
Everything around you erupts in cheers after you finish the last of the sake. Taking a look around you, you discover a crowd of oni that watched your fight and are currently celebrating your victory. Yuugi is among them, of course, but about half of the oni in the building are loudly cheering with excitement. Presumably they were watching the entire time, and you were just too engrossed in the fight to notice. You don't really know how to react to react to such a crowd, so you just try to stand still and look dignified.
“Great fight, Reimu! I knew you could do it,” Yuugi says, still grinning like a madwoman. “Now, let's get some answers out of her.”
Yuugi gets down on her knees and presses the sake box against Natch's lips, then begins to pour. Some of the remaining liquid flows into her mouth, but Yuugi is lifting the box too quickly, and much of it just drips down her face and onto the floor. Natch coughs from the excess fluid and sits up, forcing the sake box away from her. She looks worn out, but is significantly more conscious now than a second ago.
“You lost,” you say to get her attention. “Now, answer my questions.”
Natch sighs. “Yeah, yeah. Ask away.”
She already knows what you're after, but whatever. You'll spell it out for her. “The girls. The ones the spidergirl dropped off here for you and others to rape. Where are they?”
“That's easy. We sent them home.”
What? She's an oni so there's no chance that she's lying, but... that is certainly not what you expected to hear. “Maybe you should start from the beginning. What all happened?”
“Well, Yamame came by one day and dropped a naked human girl off in the middle of the village. The girl seemed to be suffering from something; she was really red, and was breathing really hard and stuff. I don't remember exactly when this happened, but it was a while ago. Yamame told us that she had infected the girl and turned her into a braindead slut, and us oni should rape her as much as we want. So we did. We lost interest in her after about two weeks, and that infection or whatever wore off anyway. So we sent her home.”
“I... I see. Was she the only one?”
“No, there were a few others. I don't remember how many. But not a lot. She dropped a few other girls off in the same way, but this was always months apart.”
“I assume you fucked the other girls too?”
“Yep. They were begging for it, it'd be rude to turn them down.” That's certainly one approach to it. Although you can relate, considering how Yamame got you too.
“How'd you send them home? Did you make certain that they made it back to the village safely?”
“Hmm,” she pauses and thinks the question over. “No, I guess not. Someone escorted them close to the mouth of the cave, and gave them some food for the journey. I guess it's possible something could've happened to them afterward.” She really doesn't seem very concerned for their safety, although they did at least do something.
“And all of the girls are gone now, correct? When did the last one show up?”
“...About six months ago, I think? And yes, she's gone. None of them stuck around for long. Most humans are just too boring. Most.”
“I see. Thank you, that's all.”
“That was a good fight. Reimu, was it? You owe me a rematch.” With that, she closes her eyes and drops her head to the floor. She's asleep in an instant, and begins snoring loudly. Well, you got what you came for, so you'll leave her alone.
Yuugi walks up to you and lifts you off the ground with both arms, forcing you into a tight embrace against her warm chest. Your face presses into her relatively-soft breasts, muffling your surprised complaints. “Alright! Time for my prize,” she sings. You try to push away from her, at least enough to speak properly, but to no avail. It seems she got the message, at least, as she adds, “Don't you remember? You said I could fuck you. If I can't fight you, I'm at least going to do this.” Oh. Well, that's fine, then.
However, instead of carrying you back to her house, Yuugi simply walks up to a side of the pub and sets you down against the wall. She's still grinning, so... yep, she wants to do it right here. While you're not really squeamish about people watching, it is kinda unsettling to do it in front of so many strangers. On the other hand, there's still four oni going at it on their own, so you won't stand out too much.
Yuugi grabs her skirt by the hem and forces it down to the floor, taking any undergarments she was wearing with them. Her massive cock springs into the air, fully erect and dripping with precum. It's even bigger than you remember! Although that's probably an issue of you forgetting, rather than it actually growing.
“Hurry up and take your skirt off,” Yuugi says, frowning. She sounds impatient, but judging from last time, she'll wait if you tell her to.
“Hold on, you can't rush this! Don't forget that I'm a human. I need to get ready first. It'll go quicker if you help; start by taking your shirt off.” You grab your skirt and pull it down, then take off your panties and place both against the wall. Your pussy is somewhat damp just from the sight of Yuugi's incredible cock, but it's not nearly enough to accommodate her massive girth.
“Hmm? What for?” Yuugi asks, puzzled. You'll have to teach her what “foreplay” means some day.
“So I can see your tits. It'll help me get wet, so just do it.”
She probably still doesn't understand, but she takes her shirt off anyway. Her huge breasts are restrained by a tightly wrapped sarashi, which she takes the time to carefully unwrap. Meanwhile, you lower one hand to your clit and begin to stroke it. The sharp stimulation when you aren't fully ready feels more weird than good, but it's necessary to get wet in such a short time.
Yuugi tosses her wrappings on to the floor. “Okay, now lean closer to me,” you instruct, “and let me touch you. It'll only take a minute.” It should feel good for her too, even if it isn't enough to overcome her patience. She obeys and steps towards you, bending over to bring her tits close to your face. They hang delectably from her strong chest, just begging for you to caress them.
You raise your right hand and grab one of Yuugi's breasts from below, letting its weight sink into your palm. It's very firm, but still the softest part of her body. Your fingers barely sink into her voluptuous mound as you squeeze her tit, savoring the heat emanating from it. Her breasts really aren't very sensitive, but that doesn't stop you from pressing your face against her other breast and sucking on her nipple. It has a pleasant taste of sweat and sake, and grows erect in your mouth.
Her cock throbs invitingly in your hand as you close your fingers around it. It's so thick that your fingers can't fully wrap around her girth. Just touching it is enough to make you shiver with anticipation. This amazing shaft will be inside of you soon. It entered you just fine before, so there's nothing to worry about. You move your hand to her tip and coat your palm in her abundant pre-cum, then rub it over her shaft. It's not enough to really lubricate it, but it should be better than nothing.
“Okay, I'm ready,” you announce. Yuugi suddenly looks thrilled, and lines her tip up with your entrance. Even stroking her dick did little for her, so she's eager to get started. “Just... be gentle, please.” She wouldn't hurt you on purpose, but it's worth repeating. Just in case she forgets how relatively fragile you are.
Yuugi pushes forward, sliding her tip past your lips. Her massive girth spreads your walls to their limit, completely filling your pussy with her hot shaft. The stretching hurts, but the sensation of being so full feels amazing. Every tiny bump and ridge on her magnificent cock sends waves of pleasure through your entire body as they scrape against your walls. You exhale, unable to hold your breath during this intense stimulation.
You look down and watch Yuugi's thick cock slowing sliding inside of you. She's moving very slowly, which is good, since your body couldn't possibly handle anything faster. Despite this, your pussy is yearning for her to slam it in and fill you to the brim.
She stops moving once she's about halfway inside of you. That's all of her ridiculous length that will fit inside of you, considering its thickness as well. You pant just from having it inside of you, savoring the sensation of being completely filled with a single cock.
It feels like your pussy has adjusted to being filled, so you signal for Yuugi to begin moving. She slowly pulls out of you, moving a little bit faster but still agonizingly slow. Once just the tip is still inside of you, she thrusts forward and fills you once again. This repeats several times, with Yuugi gaining speed with each movement.
You moan as her cock slams into your aching cunt repeatedly. The pain has faded completely, replaced with a searing pleasure as her thick shaft scrapes against your walls. Every thrust makes your body bounce a little from the impact, even with Yuugi still moving at a subdued pace. You can feel your orgasm building while her incredible dick ravages your insides.
Her shaft throbs inside of you before she ejaculates, covering your insides with a single shot of her thick cum. She hurriedly pulls out while her cock continues shooting inside of you. The increase in speed combined with the heat from the cum brings you over the edge, and you cry out in pleasure as she continues to spray semen onto your gaping pussy. You pant from the experience, the massive penetration finally over.
Yuugi gets dressed while you just lie there. Fatigue rushes in once the afterglow fades, and your hips start to hurt again after a minute. Still, it was an incredible experience.
“You alright, Reimu?” Yuugi asks while tying her sarashi around her chest.
“Yeah, I just need a few minutes. Thanks.”
“Not a problem. It was great for me too. You're the funnest human I've ever met. We really need to fight again, though! I wanna see how much you've improved!”
“Uh, maybe some day, Yuugi.” Maybe if you actually get significantly stronger. She seems to think you do nothing but train, if she expects that you'll ever be a real match for her. “For now, I'm just having a nice vacation.”
“Hmm. Well, suit yourself.”
You feel a bit better by the time Yuugi finishes dressing, so you ask her to help you up. Your legs are fine for the moment, although you'll probably be sore tomorrow. You pick up your skirt and panties and carefully put them on. None of the oni seemed to have been watching you; sex is probably a common enough sight down here that no one cares, even if a human is involved.
The issue with the missing girls turned out to be a non-incident, and your body can't take any more of Yuugi's idea of fun any more, so there's nothing left to do in the former capital. You head further down, towards the Palace of Earth Spirits.
