Volume 1, Chapter the Second - The Oni that Steals Bodies

This chapter is updated by NovelFree.ml

Ryou masturbated with his female body throughout the night.

How many times had he cum? As the number had grown, he had grown accustomed to the pleasure that rapidly grew sky high and he had grasped the process needed to reach orgasm. He knew all of the pleasurable parts of his girl’s body.

He had suppressed the moans by biting down on his blanket, his consciousness had nearly slipped from his grasp more times than he could count, and he had passed out with his entire body convulsing by the time the sky began to brighten.

Yet once morning came, he woke up earlier than usual.

(—————!! Th-they’re gone! And…it’s back. I’m…a boy again.)

He quickly checked his chest and crotch and was relieved by the familiar sensations he found, but he also regretted not being able to experience that dazzling pleasure any more.

(That…wasn’t a dream, was it?)

His sheets were so soaked with love juices he almost thought he had wet the bed.

The sweet feminine smell of sex could not be passed off as sweat and his male body reacted to it. When he realized those erotic juices had come from his own female body, the swelling at his crotch grew even harder.

(I barely slept last night. If I wear myself out any more and fall back asleep, I’ll be late.)

Even so, he stuck a hand in his nectar-soaked boxers and grabbed his erect penis. The sensation seemed lacking compared to the feminine pleasure, but it still provided a throbbing arousal different from that of a vagina.

(But…I can still shoot off one load, right?)

He prepared to stroke his manhood that had grown ferociously hard and thick as he recalled the pleasure he had felt with his girl’s body.

But…

“Morning, Ryou-chan. Time to get up!”

Someone threw the door open without knocking.

“Ah! Y-Yume!!”

He frantically pulled his hand from his boxers when he heard her cheerful voice. He just barely made it, but he did not think she had seen. He pulled up the light summer blanket to hide his swollen crotch.

He had woken up early, but a fair bit of time had passed without him noticing.

“Ha ha. This is rare. You’re already up. You usually won’t wake up even when I shake you. Hurry up and get dressed. Breakfast is already ready~.”

That had been close. If he stayed in bed, she might just jump on top of him, so he quickly got up. Even so, his cousin sat down by the pillow with the feminine roundness and natural charm of her body contained within a school uniform.

The navy blazer with red ribbon was pushed out almost to bursting by her giant breasts which bounced to demonstrate their extraordinary softness and mass.

Her short strawberry-colored skirt fluttered up enough to see her pink panties.

His heart pounded at how defenseless she was acting even if he was her cousin and her peaceful and carefree face moved in close.

“D-do you need something!?”

“Hmm. I thought she looked like you, but I guess not. I had a bad dream last night and I thought the girl who saved me looked a lot like you.”

His heart leaped up into his throat. He tried to turn away, but Yume only moved her face in closer as the twintails of her wavy chestnut hair swayed. The intent gaze concerned the boy.

“Hmm. You do have a girly face, but you’re definitely a boy.”

Her breath tickled at him and their lips would touch if she leaned in any further. But before that happened, her ample breasts were going to press against his upper arm.

“Th-that’s enough nonsense for this morning! N-now, I need to get dressed, so leave! We’ll be late!”

“Oh, right. Sorry. I’ll be helping your mom downstairs.”

Even as he cruelly drove her away, she gave her usual full-faced smile and jogged out of the room. Ryou wiped the sweat from his brow as he heard her footsteps heading down the stairs.

“She thought it was a dream… Well, that is a lot like her.”

He had asked his parents, aunt, and uncle not to tell Yume that he had turned into a girl as Onikiri-hime. He had not expected her to find out, but he was glad to see she was not pursuing the issue any further.

“But she still had to mention the girly face that I’m so bothered about…”

A feminine face could have some charm if it came with the right kind of beauty, but his only looked boring compared to the dignified look when he was a girl.

He was fairly tall, but all of his nutrients must have gone to his height because he had a slender build with skinny arms and legs. He had once been forced to wear a skirt as punishment for losing a game, but it had suited him a little too well and created something of an unpleasant atmosphere.

“But I’m back to being a boy now, so I guess it doesn’t matter.”

He put the navy blazer and gray slacks of his uniform on that slender body, tied his red necktie, and started downstairs where he could hear Yume and his mother chatting.

Yume would eat breakfast early at her own home and then help Ryou’s mother. She seemed to like watching him eat.

He did not want to lose this time with her, but he still wished she would use more of her busy morning time on herself or just sleep a little longer.

He also wondered how she felt about him. They were cousins and had lived next door since they were born, but did she feel anything more than that?

He wanted to ask, but he could not. When he thought about not receiving the answer he hoped for or about destroying their current relationship, he could not work up the courage.

Yume walked to school alongside him with a cheerful smile that was oblivious to that inner conflict.

“So your room was partially destroyed and you slept right through it?”

“Not much can wake me up once I fall asleep. My dad apparently carried me to the guest room, but I had no idea and was shocked to find myself in another room when I woke up.”

She had been told there was a powerful earthquake overnight and that it had made a mess of her room and only her room. It was an incredibly forced explanation, but she did not doubt it in the slightest.

That was just the kind of girl she was. If someone else told her there was not an earthquake the night before, they could just tell her the epicenter had been right below her room’s floor so it had only shaken her room.

She would believe it. It was just who she was.

(At this rate, is she going to completely forget about the “dream” in two or three days’ time?)

He could not keep his eyes off of her adorable smile as he thought.

(But…I can’t believe we have powers like the main family…)

Ryou’s expression clouded over as he recalled what his and Yume’s parents had told him the night before.

He had heard before that the main Ichijou family had the power to control Oni and exorcise monsters. Around when he and Yume had been born, a great number of the undead had apparently arrived from overseas and the main family had driven them out. He had been taken there for a visit just once when he was younger. He remembered people with a uniquely frightening aura sitting silently in a large old-fashioned house.

A tremor ran through him as those long-forgotten memories rushed back. Goose bumps rose on his arms.

Yume had been with him then, so he glanced over at her, wondering if she remembered. But then a powerful slap struck his back.

“Why are you zoning out like an old man so early in the morning!? Did you forget to eat breakfast!?”

“Nwaaah!”

An energetic voice reached him on the way to school.

The unrestrained voice caused his ears to ring and he turned around with a grimace.

“Morning, Kimino-chan. Ryou-chan did eat breakfast. Um, he had two eggs, bacon, a salad, miso soup with daikon, and…”

“Yuuumeee!! Morning! You’re as cute as ever. You’re so soft and your tits are so big! Now, let’s see how much they’ve grown since yesterday!!”

“Ah! Th-that tickles, Kimino-chan.”

A slender body with muscles built from swimming energetically circled around front and gave Yume a good morning hug. The boyish and lively face gave an attentive smile and solidly grabbed Yume’s weighty breasts in both hands.

She was Sakatani Kimino.

She was childhood friends with Ryou and Yume and she was currently a classmate.

The other students stopped to watch.

Even if it was over the clothes, it was quite shocking to see a girl so boldly grabbing another girl’s breasts.

After a gasp of surprise, Ryou swung a somewhat powerful karate chop down toward the back of the reddish semi-short hair of the girl teasing Yume.

“Give it a rest, you idiot! We’re in public!!”

Undeterred by the attack, she spun her healthy body around.

“Heh heh heh. Jealous, are we? You want a nice feel of Yume’s alluring breasts too, don’t you? They’re so big, so soft, and so wonderful!”

She moved triumphantly toward him.

(Y-Yume’s tits…)

He indomitably held his ground against her strange intensity and he desperately feigned calm on his blushing face. He kept his cousin’s giant breasts in the corner of his eye and for some reason recalled the feeling of his own breasts that he had teased so thoroughly while he had a girl’s body the night before.

“D-don’t be silly. I don’t want to-…”

“Ahh~ Kimino-chan…”

He trailed off when he saw his cousin blushing and covering her voluminous chest with her hands after escaping her childhood friend’s grasp. He was afraid she would mistakenly think he did not want to touch her breasts in particular.

That was when Kimino proudly spoke up while pushing out the meager but well-shaped bulges inside her blouse.

“Oh, I see. Ichijou Ryou-kun, are you more into beautifully-shaped breasts that fit just right in the hand?”

A boy could not help but stare at a large pair of breasts, but it was also hard to resist these smaller ones when they were within arm’s reach. Those modest mounds on her slim and well-trained body were obviously a trap, but he was still drawn to them.

He subconsciously gulped, and then…

“Okay, that’s enough of teasing Ryou. Let’s go, Yume.”

Kimino turned her back as if to say “that’s all folks” and headed for school lest they be late.

“Eh? Oh, r-right… We’ll be going on ahead, Ryou-chan.”

As her childhood friend returned to normal and tugged on her hand, Yume left while looking worried about her cousin. Her body had been weakened during the attack the night before and this had done a fair bit of psychological damage.

(Ha ha ha… That stupid girl… Dammit, who needs a flat chest anyway…?)

The looks of pity from the other students pained him.

He kept his sour grapes in his heart because he was afraid of what would happen if she heard him and he weakly walked down the path to school.

“Gym for first period? Whoever came up with this schedule is insane.”

Only the students with morning sports practice had any energy. Ryou nodded at the complaint of his equally unathletic classmate. The girls class also had gym and they had apparently been tasked with endurance running. The boys could hear the loud booing from the girls.

Kimino looked dejected and he gave her a look of triumph to get back at her for earlier, but she raised her middle finger in response. That girl was far too crude.

Next to her, every contour of Yume’s ample chest was indecently evident inside her gym shirt. Her plump bare legs and her large butt making its presence known inside her bloomers produced a charm that kept all the boys glancing her way.

The twintail girl waved over with an oblivious and defenseless smile. He mouthed “don’t push yourself too hard” and she nodded.

His cheeks started to relax at that adorable behavior of an obedient little creature, but…

“Comfy eye contact with your busty cousin first thing in the morning? I’m jealous, Ichijou~.”

An uttered curse reached him from behind and a thick arm grabbed him around the waist.

“Wha-!? Kasa!!”

“Heh heh heh. Only a fool lets me sneak up behind them. This is divine punishment for getting your own love comedy. Eat my Adam Suplex!”

Ryou was completely caught from behind and could not break free.

He would soon be thrown onto the thick mat for the running high jump. It would not hurt, but his pride as a boy refused to let himself be thrown.

He lowered his hips and the resistance caused his gym shirt to slip up and the arm around his waist slid up to his chest. And as soon as they touched his nipples…

“Kyaaaah!!”

It felt like an electric shock.

He could not hold in the girly scream and he crouched down on the spot.

(What was th-that…?)

“H-hey, you all right?”

“Um, yes… You just rubbed me weird and it surprised me.”

As Ryou curled up and held his chest, his classmate looked worried he had gone too far. The boy held out a helping hand as Ryou tried to feign calm and stand up. And once he took that hand…

“Hyawah!!”

This time, his heart started beating oddly fast. He felt weirdly disturbed by the solid grasp of his friend’s fingers and thick masculine palm, so he backed away.

He lost balance and his slender body fell back onto its butt.

“H-hey, Ichijou?”

“S-sorry. I didn’t sleep much last night, so I’m feeling kind of faint. I-I think I’ll go lie down in the infirmary a bit.”

He answered his worried-looking classmate and stood up before the boy could touch him.

He said he was fine and rejected the offer to go with him. He controlled his impatient legs and pretended to be sick so he could head to the infirmary.

(What was that feeling? It felt as sensitive as when I was a girl…)

The faint smell of disinfectant stung at his nose as he threw himself onto the infirmary bed and stared up at the white ceiling. He no longer felt that way. He hesitantly touched his own nipples, but it only tickled a little and the maddening explosive sensation from his girl’s body was absent.

(Is that still lingering with me in some weird way? I can’t do any kind of wrestling like this.)

Boys generally did not touch each other like girls did, but he was still worried it would affect his friendships in some strange way.

(Is another Oni going to attack Yume? If so, will I turn into a girl…into Onikiri-hime again?)

He intended to protect Yume no matter what happened, but if possible, he wanted to avoid doing anything as frightening as fighting those Oni. And gaining a girl’s body would bring problems of its own.

He closed his eyes as his worries spun through his head and sleepiness quickly set in.

He dozed off while listening to the distant voices of his classmates in the schoolyard, but then the infirmary door opened.

“Are you okay, Yume? You need to watch your step.”

“I know. Sorry, Kimino-chan. I just started feeling faint all of a sudden.”

He threw open the partition curtain when he heard two familiar voices.

“Yume! What’s the matter!? Did you trip!?”

“Hweh, Ryou-chan!? What’s the matter? Are you sick? You need to lie down.”

“You’re the one that needs to lie down. C’mon!”

Worried for her cousin who got up from the infirmary bed, Yume walked unsteadily over, but her childhood friend pushed her into the adjacent empty bed.

“Can you believe this girl? She collapsed right as the endurance run began. Are you getting your sleep? …Actually, I guess it’s impossible for you to not get enough sleep.”

She would start dozing off by about nine at night and would be asleep on the floor half an hour later. And once she fell asleep, she would not wake until morning.

This childhood friend had known the girl’s incredible sleeping habits for a long time, so she got Yume to crawl under the blanket. Yume looked embarrassed, but her eyelids were already heavily closed.

Her poor health was almost certainly due to the events of the previous night. A violent Oni had awoken her from her slumber, attacked her, and devoured her spiritual power. However, Kimino would not believe that and it would only worry her further if she did.

“I’ve been feeling a little tired lately too, so I think I’ll join you there. We can get some nice shutey-…that was fast! She’s already asleep…”

The childhood friend’s eyes widened at Yume’s abnormal ability to fall sleep. She then sighed and sat down on Ryou’s bed.

“Hey, I’d kind of like to get some sleep too.”

Her long and healthily toned legs sprawled carelessly out from her bloomers.

When that energetic girl rudely spread her legs, it did not look indecent. Instead, her lively charm drew the boy’s eye. Unsure where to look, he peeked over at Yume’s sleeping face. Kimino spoke mischievously to him as he let Yume’s happy expression soothe him.

“Go right ahead! I don’t mind if you go to sleep. How about you rest your head in my lap while you’re at it? Or would you have sweeter dreams resting your head on Yume’s chest?♪”

It looked like he would have to give up on getting any sleep. Plus, it got on his nerves how she always teased him. Since Yume was asleep, he decided to fight back for once and rolled over to place his head on his childhood friend’s bare lap.

“Hyah!! Ry-Ryou…”

“Yes, I think I’ll take you up on that offer. Wake me up once the class is over.”

In her uniform, her thighs would have been covered by her skirt, but they were bare now and he felt their warmth below the back of his head. He did not want her to see his rapidly reddening face, so he rolled onto his side. That brought the crotch of her navy blue bloomers into view.

(Wh-whoops! I turned the wrong way!!)

He ended up staring at the mound of her pubis pushing out the fabric and he completely lost his chance to roll back over. He was certain she would slap him and he braced himself, but…

“O-okay. I-I’ll wake you up…once the bell rings…”

She replied in a barely audible voice. He gulped and prepared to sit up, but her hand stopped him by gently touching his hair.

“Kimi…no…?”

She was acting different from normal.

She had a way of meddling and would sometimes tease him in sexual ways to see his look of surprise, but she had grown oddly obedient. He wondered if this was the lead-up to some kind of teasing, but then she spoke in a quiet, scratchy voice.

“H-hey, Ryou. Is my l-lap…comfortable?”

The flexible and feminine softness of her thighs was more than just comfortable. After rolling over, his ear and cheek were pressed against her smooth skin and it filled him with excitement.

However, resting his head on a girl’s lap for the first time had left him far too aroused to sleep. A crotch wearing bloomers sat right before his eyes and his gaze was glued to the faint vertical line visible through the fabric.

He was close enough for his breath to reach her, so he tried to suppress his heavy breathing while having difficulty finding an answer to her question. Meanwhile, she asked him again while softly rubbing his hair.

“C’mon…tell me… I want to know what you think… It’s the least you can do…after I let you do this…”

“Y-yeah… It’s comfortable…”

His voice was scratchy and he gulped.

“I see… Then I’ll tear that head off so it can sit in my lap forever.”

Kimino’s voice suddenly transformed into something horrific. This was fundamentally different from the tone she always used to tease him. He felt a chill at the blatant malice in her voice. He quickly tried to get up, but the fingers in his hair grasped his head and pressed it to her lap so hard he thought his head would burst.

“Gwaaah! Ki…mino…!?”

He was shocked, but he somehow managed to turn his head enough to see her face out of the corner of his eye.

Some hint of his childhood friend’s boyish face remained, but her eyes were bloodshot and her smile was filled with violent joy.

Sharp fangs poked from the corners of her mouth and two horns had grown from her head, so she was undoubtedly an Oni.

“What…? Kimi…no! Kimino!!”

Her feminine curves were overwhelmed by bulging muscles like a bodybuilder who had gone too far. Her body’s height and thickness grew more than two sizes larger and her gym shirt tore to reveal the bulges that might have been breasts or pecs.

The bloomers alone remained to hide her crotch, but the fabric was bulging to the point of bursting. The muscular butt could not hope to fit, so the back dug deep into her butt like a thong.

She did not seem at all embarrassed and she continued holding down Ryou’s head with enough monstrous strength to strain his skull. She also sent a sticky look all across Yume’s sleeping body.

Ryou was shaken by a hopeless sense of despair. An icy chill ran down his spine and his vision grew dark.

Oni were spiritual beings, so they apparently tended to take physical form by possessing people. That person would undergo a hideous transformation and gain inhuman strength.

(Why did this…happen to Kimino!? Don’t tell me it was because she was with us!)

The Oni had tried to attack Yume and Kimino was the only other one there.

They could not possess Ryou. After all…

“Kwaaaahh!!”

The boy’s body emitted a bluish-white light as the Oni held his head down.

He groaned at the sensation of his body’s structure changing from within and the change showed itself on the surface.

His chest rapidly swelled out into seductively ripe fruits that pushed out his PE shirt.

His shorts also grew tight as new soft flesh grew on his butt. Just like in his around-the-house clothing the night before, the shorts dug into his crotch and filled him with a throbbing that made him fidget.

His waist grew thin and his bodylines gained supple curves.

His eyes grew sharp and angled, giving him a cold beauty, and his hair grew into a long black ponytail.

Ichijou Ryou visibly transformed into Onikiri-hime who gained the power to slay Oni in order to protect Oninagusamu-hime, the chosen sacrifice of the Oni who hated the Oni Controllers.

The power to control Oni was only held by women and the same was true of the power to slay them.

He had been bon a boy, so his sex was forced to change.

(Kh… I’m turning into a girl again…)

He did not have time for confusion or embarrassment.

He had to protect Yume from the Oni’s villainy.

(But…Kimino!!)

The Oni attacking them now was the childhood friend who had played with them since they were little.

(What do I do? I can’t hurt Kimino! But Yume’s in danger.)

He could not attack. He managed to break free of the hand squeezing his head and he rolled himself and the Oni from the bed to get as far away from Yume as he could.

“Gh!”

His back slammed into the floor and the Oni straddled him as he groaned and gasped for breath.

“Ahh!! G-get off of me!”

“Curse your interference, Onikiri-hime. I’ll eat you first so I can take my time devouring Oninagusamu-hime! And aren’t you even going to attack? What a weak guardian!!”

It had to know the reason why and it gave him a look of blatant scorn.

“Still, you are overflowing with spiritual power. You alone might be enough to fill my stomach.”

The Oni in Kimino’s body licked its lips above the “girl” on “her” back and sucked at one of the breasts through the gym shirt. Its pursed lips sucked at the erect and throbbing nipple.

“Hyaah! N-no!! Stop tha-…hwaaah! Don’t suck at it! I’m a guy! I…how could this be happening…ahhhh!!”

“Geh heh heh. Spiritual power is practically gushing from this tip.”

The small bead exploded with such hot sensitivity that he thought his mind was being sucked from him.

The obscene vacuum noise of bubbling saliva tickled at the skin and he could not suppress the tremor that ran through his entire body. The tongue rolled around the nipple as if to help the spiritual power out and an almost painful throbbing filled the entire breast.

(Ahhh, what is this!? Something’s filling me…deep in my stomach… Oh, no… At this rate, I’ll cum…)

The girl’s body was reacting to the pleasure.

He was unable to attack his childhood friend even in Oni form, so he could only submit himself to the teasing and tremble seductively on the floor while uttering shrill moans. He was breathing as heavily as after a full-speed sprint and his entire body was soaked with a sweet feminine-smelling sweat, but the Oni’s lips finally left his breast.

(Ahhh!! It’s already ov-…no, I mean it’s finally over…)

Shocked by the desire in the back of his mind for it to continue, he focused on the opposing feeling of relief. He was wriggling his body and shaking his breasts, but he insisted to himself that did not come from a desire for it to continue. Then the Oni’s face moved lower than the breasts and instead buried itself in his crotch.

“Wait! No!! Not here! Fwaaaaaahaaaaa~~~~!!”

A hot breath blew on the crotch.

The shorts dug even further into his crotch and the Oni’s tongue stuck into the feminine slit through them.

(Khhh. My underwear…is digging into my slit!! If you lick me there…!)

The Oni licked from the bottom to the top of the pubis and he felt a joy fill his crotch that made him want to press his hips up against the tongue.

As that sweet sensation dyed his mind, the clitoris throbbed madly from the cramped stimulus. He felt the vagina loosening and opening as hot sex nectar flowed out.

“Keh heh heh heh… Just a little lick and these filthy juices are already flowing? What a horny Onikiri-hime.”

“If you do that…anyone would…fwaah, ahhh!!”

Sweet moans spilled from his lips as he was ruled by pleasure incomparable to that of his boy’s body.

His arms and leg went limp and he could not even try to escape.

“Maybe so, but you loosen up way too easily! Your pussy’s already soaked!”

“Ahhh, no!! Ah, ah, ah, ahhhhhh!”

The shorts and boxers were dripping with saliva on the outside and love juices on the inside, but the Oni slid them both to the side, exposing Ryou’s crotch. A silly moan spilled from his lips at the way the fabric rubbed as it was dislodged and at the release from the tight confinement.

“It’s completely loosened and opened up. Keh heh heh heh. You must want something in there pretty bad.”

As fingers with pointed nails pulled back the outer lips, a tremor ran down Ryou’s spine.

“Hyah…ahhh!!”

The Oni stirred up the thin inner lips and the flesh within, so a sweet sensation rushed up to his head.

The stickiness of the love juices raised the pleasure even further.

He subconsciously arched his back and forced up his giant lovely breasts. The shirt was soaked with sweat and the nipples stood visibly erect as if begging for the pleasure from earlier.

However, the Oni’s lips sucked at the vulva with its vagina and urethra exposed.

“Fweeeh, eh, ehhhh. Ahh, hwaahhhh! Fwaaaaahhh!!”

Even the love juices deep inside the vagina were mercilessly sucked out. The tongue forced apart the sensitive slit as it dug into the vagina and rolled around the clitoris.

“Hyah!! Ahh! Not…there…ahh, that’s too rough!! I’m going insane…my mind is going to break! Fwehhh. No…fwaaaaahhhh!!”

The hood was pulled back from that most sensitive bead and it was licked so hard it was crushed under the pressure.

The pleasure hit him like physical blows and the next stimulus would explode inside him before the previous one had faded.

(Kh, hh, ahhh! If you…lick me…there…I’ll go…crazy!)

His heart was pounding so hard he thought it would burst and he had trouble breathing.

Waves of pleasure shook his entire body and sweet moans surged from his mouth.

“Ahh, your spiritual power is quite delectable. I think I’ll force out some more.”

Spiritual power apparently flowed out when he felt pleasure.

Having it eaten only increased the sluggishness of his body. The Oni that had taken his childhood friend’s body stuck its finger into Ryou’s vagina to suck out even more of his power.

“Hyah! Ahhh!! No, don’t stick it…in!”

The previous pleasure had completely loosened up the hole, so the fingertip easily slipped inside. A shock ran through his hips and sapped his body of strength. This was a crisis, yet his breasts bounced around.

This was the second time he had become a girl. He had so little experience with this body that whenever anything pleasurable happened, he could not suppress the desire for more. He knew he should not, but he thrust his hips out to shamefully beg for more.

(Ahh, I’m acting like a horny slut. Fwaaaahhh~~)

However, that further built up the masochistic arousal inside him.

He intentionally insulted himself in his thoughts while his lower body convulsed.

“How can you say that when your pussy’s this wet? You’re even pushing your hips back up against my hand. Here, I’ll push it in even deeper!”

“Ah, ahhh, ahhhhhh!! I-it’s going in…hyaaaaaaaaaaah!”

When masturbating the night before, he had been too afraid to stick a finger in here. He had felt like experiencing that pleasure would cross the point of no return between boy and girl.

And the sweetness that exploded inside his vagina told him he had been exactly right.

The sticky vaginal walls were forced open he felt an overwhelming presence moving deep within his body. And yet this was just a single finger.

What if it were a penis instead? As that sudden question came to mind, he realized he was thinking like a girl and he burned with embarrassment.

(E-eeee! The finger’s…inside me. It’s stirring me up!! Ahh, amazing! How can a finger inside you…feel so good!! Ahhh, I can’t stand it!)

Even so, his mind was ruled by the masochism of someone else having their way with his girl’s vagina.

As the vaginal walls tightened they did not push the foreign object out. In fact, they tightened down on it to increase the sensation of contact. The honey pot deep inside continued to throb as it produced more and more love juices that provided an obscenely wet noise to the fingering.

He was worried that the rough treatment would break his hymen.

(Do I…have a hymen? I’ve never had sex… Wait, why am I thinking about this?)

He was a boy and yet he was worried about his hymen.

His female sexuality ruled his thoughts and drowned out his self-consciousness as a boy.

As unease rose within him, the Oni’s playfully wriggling finger found a point of slight indentation inside the vagina and roughly scraped at it.

“Ahhh!! Fwah, not…there! Ahhhh, stop…ahhhhh!!”

An even more powerful sensation directly shook Ryou’s womb.

(Hyaaah! What…is this? It’s…too good. It’s rising up…within me!!)

The fingertip had been stirring up the vagina sometimes roughly and sometimes gently, but now it focused on a single point and applied pressure at a set rhythm.

The sexuality within Ryou’s female body had risen plenty already, but that brought it up to dangerous levels.

“Ah, ah…ahuhh! No, you’re kidding…fwaah, why? Ahh, something’s…something’s coming…fwaaah, help…me…ah, no…”

The throbbing of his womb was incredible. Goose bumps covered his skin as it trembled in anticipation.

His eyes widened as his face twisted into an expression that may have been agony or may have been a smile. His butt tensed up in preparation.

“Hmph! Now cum, Onikiri-hime!”

With an unexpectedly strong attack on that pleasure spot, the Oni also lightly flicked Ryou’s clitoris with its tongue tip.

“Hyah!? No, ahhhh, no, here…here it comes…I’m cummming!!”

Light exploded in the back of his mind and his consciousness flashed in and out.

The intense pleasure from the clitoris and vagina raced across his entire body.

A wrenching longing filled his womb and intense convulsions washed across him.

“I’m…cumming. Fwaaaaaah! Ahhh!! Hyah, fwaaaaahhhh~~~!”

His entire body shook and his crotch thrust up as high as it would go. Climax fluids squirted out like he was pissing himself and soaked Kimino’s possessed face.

(Ah…ah, ahh…vaginal…orgasm…is way too…good…)

His hazy mind was still flashing in and out as he gave himself over to the pleasure.

If it felt this good, he wished he had put his own finger in the night before.

He blankly recalled that this state was exactly what he had been afraid of, but he let himself bask in the tingling pleasure of the throbbing vagina and womb that made the entire girl’s body feel great.

“Hah hah! Now this is some amazing spiritual power!! There’s so much and it’s so thick! And to think I still get to devour Oninagusamu-hime after eating this!!”

The Oni rejoiced in the overflowing spiritual power while viewing Ryou’s sexual state.

The thick pleasure showed no sign of fading, so his entire body had gone limp and he could not move a single finger.

His heart alone was beating like an alarm bell and steamy sexual sweat seeped out onto his skin.

He felt like he would simply die as he soaked in the orgasmic pleasure.

And yet that thought sounded wonderful to him at the moment.

Once the Oni finished devouring his spiritual power, his life would be snuffed out.

“Yawn… Huh? It’s that cool girl who saved me in my dream…”

Yume sleepily crawled along the neighboring bed to reach the collapsed genderbent boy.

“What!? Oninagusamu-hime!!”

She had been fast asleep, so when had she woken up? Ryou had not sensed her presence and she was already nearly to his side. She had no idea this was her cousin turned into a girl to protect her and she peered into that lovely face that had grown slack from orgasm.

The Oni had been caught off guard too and looked utterly shocked.

The monster stopped feeding on Ryou’s spiritual power and tried to attack.

“Yawn~ Such pretty boobs… She’s so cool…”

But she unintentionally dodged the Oni’s claws. She seemed to still be half-asleep and she buried her face in the chest of Ryou’s gym shirt that revealed the shape of his giant breasts so perfectly.

“Boobies…nyah…♪”

“Ahh! Ah, wh-what…is this!? I’m filling with…strength!!”

Yume’s lips moved right to one of the nipples and lovingly sucked on it.

His girl’s body had begun releasing all of its spiritual power when he climaxed, but vitality rapidly filled him anew.

“Oh…ahhhhhhh!! W-wow…! Ah!! Ahhhhhh!”

He had been too limp to move a finger, but he stood up from the bed as if he had grown wings. At the same time, he had Yume roll behind him where he could protect her.

(Power flowed into me from Yume? I didn’t just recover! This power is even greater than when I started!!)

He held his arm up and an Oni-slaying sword with a glittering crimson blade appeared in it.

“C-curse you, Onikiri-hime! I thought I had sucked out all your spiritual power!”

The shocked Oni quickly flared up with anger. They were at point-blank range and the Oni’s body was much, much larger.

It tried to crush Ryou with its sharp claws and fangs.

He caught the attack on the back of the sword.

“Kh!”

He was sent flying back to slam into the infirmary wall, but he flipped around and kicked off the wall.

He held the great sword at the ready as his genderbent body flew through the air with catlike flexibility.

He flipped upside down, kicked off the ceiling to build up his momentum, and swung the blade down toward the Oni.

His breasts bounced enough to hit his chin, so they were just in the way.

“Gwoh!!”

The Oni flipped out of the way with nimbleness unimaginable from its size.

As Ryou’s attack missed and was thrown off his balance, the Oni sent a sharp kick toward the side of his head.

He dodged and swung up the blade for a counterattack.

“Are you sure you want to do that? You’ll hurt your friend!”

“————!! Kh!”

The Oni had possessed Kimino’s body, so he could not attack. He could not hurt her.

He stopped the blade just before lopping off the leg and stuck to simply dodging the kick.

(What do I do? How do I save Kimino and defeat this thing!?)

He had also held back at the last second with the attack from kicking off the ceiling.

He could not carelessly attack when the enemy was a hostage. What was he supposed to do?

He tried to figure something out as he pointed the tip of the blade at the thinly smiling Oni.

And as soon as he clung to the hilt of that magic blade…

“————!! Ah…”

Knowledge flowed into the back of his mind.

(What is…this…?)

This Oni-slaying blade had cut down countless Oni that attacked in their desire for Oninagusamu-hime.

It bore the name Zanshou and the strategies used by generations of guardians were passed onto Ryou.

“Impure Oni that yearns to devour Oninagusamu-hime. Have a taste of my Zanshou and perish!!”

There was no hesitation in those slanted eyes.

Onikiri-hime glared at the Oni with a dignified look overflowing with fighting spirit.

“What!? Cut me down and you will damage this body’s owner as well!! Are you sure you want that? …Kwoh!”

When the Oni saw that threats would get it nowhere, it made an attack.

It rushed in with sharp claws raised and fangs bared.

Ryou pulled the sword back next to his face, lowered his hips, and aimed the tip.

“Tseiiiiiiiiiiiiiiiiii!!”

Ryou’s powerful stomp shook the infirmary.

Before the Oni could grab him, he made a powerful thrust toward the chest.

Just before the tip sank in, he pulled it back.

“Gah!? Ah, ah, ahhhhhhhhhhhhhhh!”

The hideous form immediately fell to its knees.

“I-impossible!! My body…my bodyyyyyyyyy!”

Its body shook violently as a black miasma flowed out. The body quickly transformed back into Ryou’s childhood friend. She had been pierced through the chest, but there was not a scratch on her.

“That is not your body! That is Kimino’s body!!”

He made a full horizontal swing of the blade aimed at the swirling miasma.

“Gyaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhh!”

As the blood-red blade sliced through, the Oni’s true form of black smoke let out a death cry and vanished.

“I-I defeated…the Oni… I can’t believe it possessed Kimino… But that was a close one. If Yume hadn’t given me that power… Oh, and it’s all gone now that I’ve fought. But…”

The strange atmosphere had left the infirmary, so it was once more a still space that smelled of disinfectant. As the bell rang to indicate the end of the class period, the surging energy and the Oni-slaying sword both vanished.

“And…I’m really sleepy… Is that because I didn’t get any sleep last night and I didn’t get any here either?”

But the drowsiness was too powerful. It had settled down during the fight, but the never-ending pleasure of orgasm and the lethargy that followed rapidly returned.

“I can…get some rest…until second period starts…right?”

He did not think he could remain conscious any longer and all strength left his body.

Yume had fallen asleep again and Kimino had not regained consciousness after returning from her Oni form. Ryou collapsed onto the bed alongside them and was soon producing the steady breathing of sleep.
