Volume 1 Chapter 7 The First Mounting*
Edited by: Kanaa-senpai
As we left the guidance facility, a group of students waiting outside immediately swapped places with us and went in. One guy and four girls. From the looks of it, they were upperclassmen. It seemed new students rarely used the guidance facility the day after enrollment.
We walked down the connecting corridor right outside the facility and headed toward the school building where the guidance rooms were clustered.
”Room 301, right?” I asked.
”Mm…” Chifumi murmured softly.
Her unusually obedient demeanor threw me off a little.
”What’s wrong? You’re not acting like yourself,” I said, glancing at her.
”…”
She didn’t answer.
We climbed the stairs in silence. When we reached Room 301, I took out my student ID card and held it up to the mark on the door. With a soft click, the lock disengaged and the door opened.
”Alright, let’s go in,” I said.
”Okay…”
The moment we stepped inside, the door closed behind us and locked automatically. The sound was louder than expected. Chifumi flinched visibly.
The guidance room wasn’t very big—about half the size of a regular classroom. Right by the entrance were two small desks and chairs, almost as an afterthought. A partition wall stood behind the desks, blocking the view of the deeper part of the room. It also came with its own shower and toilet.
”You know what a ‘post-match review’ is, right?” I asked.
”Y-Yeah…♡” Chifumi replied, her voice already trembling slightly.
I slid the hand I had around her waist lower and gave her plump ass a firm squeeze. She accepted my blatant sexual harassment without complaint.
I set our bags on the desk and led her past the partition. A king-sized bed immediately came into view, dominating most of the small room.
This was where the so-called “post-match review” took place.
On the surface, it was supposed to be a relaxed discussion about what went well and what went wrong in the match, helping each other improve their sorcery skills through mutual feedback.
In reality, as the bed made obvious, it was a place where the winner mounted the loser.
The victor held absolute command rights inside this room.
Even if Chifumi hated me, if I ordered her to “strip and spread your legs,” she would have no choice but to obediently open them on this bed. That was the rule enforced by the school. They openly encouraged “teaching them their place.” As a result, the rate of non-virgin male and non-virgin female sorcery users at high school graduation was 100%.
Chifumi looked up at me with slightly moist eyes.
I moved my hand to the back of her head and pulled her into a kiss.
Our lips touched lightly before I pulled away.
”Minoru… you stole my first kiss~” she said with a shy smile.
”It’s my first too, so we’re even,” I replied.
Chifumi let out a soft, giddy laugh. She looked adorable.
I kissed her again, this time deeper and slower. Not really knowing what I was doing, I poked at her lips with my tongue. She hesitantly opened her mouth. Our tongues met awkwardly and began to lick each other. The slick, soft sensation was intoxicating. I greedily devoured the beautiful girl’s tongue and saliva. Since I had no experience, I hoped she’d forgive my clumsiness.
”Mmm…” Chifumi gently sucked on my lip.
She can do that? I thought. Not wanting to lose, I sucked back. We devoured each other’s lips hungrily. When we finally separated minutes later, both of us were breathing heavily.
Looking at Chifumi’s expectant gaze, I gave my first order.
”Take everything off.”
”…Yes.”
After a brief moment of hesitation, Chifumi slowly began removing her uniform.
I sat on the edge of the bed and watched. First, her skirt slid down, revealing simple white panties and her thick, juicy thighs.
”…”
Looking embarrassed, she moved on to her top. She removed her jacket and ribbon, then began unbuttoning her blouse one by one. Gradually, her impressive breasts came into view. She almost seemed to be pushing her chest out on purpose.
When her hands reached the lower buttons, she suddenly looked anxious and glanced at me.
As expected from how her uniform had hidden it earlier, Chifumi had very little belly fat.
In this world, having a softer, more protruding belly than your breasts was considered ideal. Chifumi, who only had a small pinchable amount of fat on her stomach, was basically treated like someone with a flat chest in my old world—appealing to people with specific fetishes, but generally seen as disappointing. She probably hated showing her stomach.
With a soft rustle, her blouse fell onto her skirt. Chifumi now stood in just a white bra, panties, and black knee socks. She used both hands to awkwardly cover her belly.
”Your breasts are pretty big. What’s your size? Tell me,” I ordered.
”J-cup…” she answered.
In this world, both large breasts and a large belly were preferred. Trying to make up for her small belly with her chest, she answered with a confident voice.
”And your underbust?”
”Um… 75 centimeters…” she replied, her voice suddenly small and weak.
”But my butt is something I’m confident in!” she quickly added before I could ask anything else, trying to take the initiative.
She had deliberately skipped her waist measurement… Well, it was a little soft, but nothing bad. It might make some sorcery users here frown, but for me it was totally fine. Actually, I liked it.
Her ass and thighs were deliciously thick. The way she fidgeted made it clear—she was a thicc, big-breasted beauty. Way too dangerous. A 15-year-old high school freshman shouldn’t have a body like this. Combined with that beautiful face… I was extremely satisfied with my childhood friend’s potential.
”Will you take my clothes off too?” I asked.
”Yes…”
Still in her underwear, Chifumi approached and began undressing me. Her fingers traced lightly over my collarbone, tickling me slightly. Once my shirt was off, I was topless. She had been embarrassed about her soft stomach, but mine wasn’t much different—just minimal fat over muscle. A rare body type for a male sorcery user. Closer to a swordsman’s build.
Her hands didn’t stop. She unbuckled my belt with a clink, and when I lifted my hips, she pulled my pants down.
She must have noticed how cramped my c**k looked inside my underwear. I took her hand and pulled her onto my lap.
”Hyaa…!”
The bed creaked loudly under our combined weight.
The moment our crotches pressed together through our underwear, she instinctively tried to lift her hips. I grabbed her waist and held her in place.
”…”
With our genitals touching through fabric, we stared at each other from extremely close range again.
I kissed her gently. Her expression softened, and I felt the tension leave her body.
”Alright, let’s take these off. Strip yourself,” I said.
”Uu… okayyy…”
Resigned, Chifumi reached behind her back and unhooked her bra. As she pulled the white fabric away, her massive breasts bounced free right in front of my eyes. Pale skin, light-colored n**ples. Perfect.
I grabbed them with both hands and kneaded them roughly.
”Ow… that hurts a little…”
”Sorry. How about this?” I asked, softening my grip.
”Mm… yeah… that feels good♡” she whispered near my ear.
Embarrassed, she clung to me the moment I started playing with her breasts. For a while, I enjoyed the feeling of her large, firm yet soft tits in my palms, then moved on to her hardened n**ples.
I flicked them with my fingertips and pinched.
”Hiiuuh♡♡!”
Her voice took on a completely different tone. Not bad. Chifumi’s arms wandered across my back, searching for a good place to hold on. I pinched her n**ples and shook her breasts left and right, then flicked them repeatedly. I tried everything I’d ever wanted to do to a pair of big tits.
”Ah♡… Hey…♡… Not there♡… That’s bad…♡♡”
Despite saying it was bad, her sweet, pleasure-filled voice told a different story.
Before I knew it, her hips were moving on their own, grinding my c**k against her p**sy. She was getting wet.
I moved my right hand from her n**ple, down her underboob and side, until I reached her crotch.
”Ah!? ♡♡”
I pressed my middle finger against her panties. Her dramatic reaction was immediate.
My fingertip felt hot, slick wetness.
I pulled my hand up and showed her, rubbing my middle and index fingers together before spreading them. A thin, shiny string of her juices stretched between them.
”Look at this,” I said.
”Uu~… It’s embarrassing~… You’re so mean!” Chifumi whined, her face bright red as she puffed her cheeks.
”It’s not embarrassing. It just means you’re welcoming me properly.”
”Uu… That might be true, but it’s still embarrassing!”
She turned her face away with a huff.
Maybe I shouldn’t tease her too much.
”Alright then. Let’s do it. Take off your panties, lie on your back, and spread your legs.”
”Wait a second~!? There are better ways to say that, you know~!?”
”Ah, yeah. My bad.”
Seeing Chifumi pout at my crude command, I rephrased it more authoritatively—this time like when I had taught that strong female her place.
”I’m going to take your virginity, so spread your legs. Seduce me with erotic words and gestures so I really feel like fucking you. Knowing you, you’ve practiced this, right? Show me what you’ve got.”
”!? …Y-Yes♡♡”
I applied a little pressure. Chifumi quickly lay down on the bed, teasing me just enough not to annoy me.
She slid her panties off her right leg, leaving them hooked around her left ankle, then bent her knees and spread her legs wide. Her neatly trimmed pubic hair was completely exposed.
Using both hands, she spread her p**sy open, showing me the pink inner folds as she spoke in a sweet voice:
”Please take my unused p**sy…♡ Penetrate me with your strong c**k and turn me into Minoru’s personal onahole♡ Please fill my womb with lots of your thick semen♡♡”
She swayed her hips cutely, trying to tempt me.
”An unused p**sy, huh? I’ve heard they’re tight but don’t feel that good. Can you really make me feel good?”
”I-I can♡ I trained my p**sy a lot so I can please Minoru♡ I’ll serve you desperately with my hot, tight virgin cunt♡ Please be merciful to your personal p**sy~♡♡”
The pathetic sight of her desperately trying to please me after I teased her made my c**k throb even harder.
Without a word, I pulled off my underwear. My fully erect c**k was already leaking precum at the tip.
”Ahh♡♡” Chifumi moaned softly, eyes locked on it.
I leaned in close to a visibly excited Chifumi, teasing her entrance with the head of my c**k. The sensation of her flesh was softer and more pliable than I had ever imagined. The slick, warm lubrication clinging to me sent an indescribable jolt of pleasure straight to my spine.
”I’m going in,” I whispered against her ear.
”O-okay… yes, please,” Chifumi replied, her voice trembling with unmistakable nerves.
I was nervous too; this was my first time as well. But I knew where the entrance was. The head of my c**k found its home, nestling perfectly into place. If I just pushed my hips forward now…
With a smooth, wet slide, I forced my way into the hot, tight, gripping heat of her s*x.
”Ugh…!” she gasped.
I deliberately ignored her pained expression. I felt a slight resistance halfway through, but I pushed through until I reached the end of her narrow passage.
”Ah…! Mmh!”
I stopped, my hips locked against her. Looking down, I could see my c**k fully embedded within her, a visceral confirmation of our connection. While the tactile sensation of being inside a girl was undeniable, I felt a strange emptiness at the base—my c**k was simply too long to be fully contained.
”Nn…!” she whimpered.
”Ugh!” I grunted.
I tried one final, firm thrust, but it was useless; I couldn’t reach the base. Seeing her teary-eyed, pained expression, I decided to give up on forcing it all the way in. Was my manhood just too large, or was Chifumi’s v**ina simply too shallow? Well, that was something to look forward to in the future.
”H-how is it?” Chifumi asked, looking up at me while her hips twitched involuntarily, her voice filled with earnest curiosity. “Is my… my virgin p**sy… does it feel good?”
The gentle affection that had been budding in my heart was instantly obliterated, replaced by a predatory, male desire to devour this female beneath me.
”It’s alright, I suppose,” I said coolly. “Now, make sure you serve me properly.”
”Y-yes…! Leave it all to me!” she chirped, her eyes shining with devotion.
I gave in to my raw desire and began thrusting. The wet, rhythmic slapping of skin against skin filled the room. Truly, there was nothing like the hot, constricting embrace of her p**sy; it was worlds apart from the pathetic comfort of my own hand.
”Hah… hah…” I breathed.
”Nnh♡… Nnh♡…” Chifumi moaned.
At first, my movements were clumsy, lacking the rhythm, but I gradually found my stride. I learned to pull back to rub against her internal folds and thrust deep to strike her sensitive spots.
”Fuuu♡… Ahhh♡!”
Chifumi’s reactions became more intense. Her body, once stiff with tension, began to soften and melt. She transitioned from simply swaying with my movements to actively grinding her hips against mine.
Every time I drove into her, her heavy breasts bobbed and shook. I reached out and pinched one of her n**ples.
”H-hnnn♡!” she shrieked, her entire body arching in a spasm. Perfect.
A few minutes into our session, I felt the heat building deep in my gut. I braced my arms on either side of her head, locking my lips with hers as I kept up the pace.
”Ugh… fuuuu♡♡!”
Even after I pulled my lips away, Chifumi kept her tongue extended, desperate for another taste. I looked her straight in the eyes and declared, “I’m going to c*m.”
”Yes… do it,” she whispered.
”Open the lock.”
”Yes… I’m opening it for you,” she promised.
Simultaneously, as her v**inal walls constricted around me with newfound force, the atmosphere of the female beneath me shifted. Call it the soul, the core, or the fundamental essence—whatever the name, a door that should never be opened had been unlocked, a gate that a Sorcery user is meant to guard at all costs.
”Chifumi!” I roared.
”Minoru!” she cried out.
At the very final moment, our lips met, and I emptied myself deep within her, flooding her womb with my genes, my information, and my mana.
”Nnnnnnn…♡♡♡♡”
Still pressed together, tongues tangled, I poured that mana into her body. While my lower half focused on the physical act, I used our kiss to manipulate the flow of mana inside her. My essence spread from her uterus, surging outward until it reached her heart.
”Ugh♡♡♡♡”
Pinned beneath me, Chifumi shivered—a mix of agony and ecstasy. My mana began its invasion, creeping toward the core of her magical power: her heart. Perhaps sensing a primal threat, her heart tried to resist, but my mana clung to it, slowly and surely eroding her defenses. It was like mixing paints; I felt her aura shift as my essence seeped into her, overwriting her very being. In the most literal sense, her heart was being reborn in this very moment.
As her new heart, imprinted with my data, began to beat, a surge of mana flooded through her body. Satisfied, I finally pulled my lips away.
”Puh-hah♡… ah♡… ah♡… ahhhhh♡♡”
Chifumi looked up at me, tears streaming down her face, her hands clutching at her chest. I could feel it: her door had closed, and I had placed a heavy, intricate lock upon it—one that no one but me could ever hope to open.
With this, this Majo was mine.
I slowly withdrew, and a thick, white, frothy liquid spilled from between her thighs. There was a faint pink tint to it—blood from her virginity.
”Haah… haah… haah…”
Lying there with ragged breaths, Chifumi gave me that soft, familiar, dazed smile. Just as I reached out to pet her head and tell her she did a good job, she reached down, parted her labia, and shamelessly flaunted her insides—her now-violated, semen-coated p**sy—directly at me.
”You really are something else…” I muttered.
Blood rushed back to my softening c**k, and it stood tall once more.
”Aha♡”
Chifumi darted her tongue out, licking her lips. There, upon her pink tongue, was a mark that hadn’t been there before: the crest of a Majo who had just formed a contract with a Majin like me.
I checked the clock. One hour had passed since we entered the guidance room. We still had an hour left. Plenty of time to spoil this adorable childhood friend who now belonged entirely to me.
I threw myself back onto her.

We finally left the room three hours later, having received a stern lecture from the teacher. As we walked toward the school gate side-by-side, Chifumi grumbled with a pout.
”It’s all Minoru’s fault for being so lewd…”
”Oh, like you weren’t into it!”
The fire we had stoked hadn’t cooled down in just an hour, so we had extended our time. Thankfully, the teacher had set aside some extra hours for us since it was our first session.
”Sigh… I’ve really become Minoru’s Majo now…” she sighed.
”I guess so.”
”You’d better treasure me, or I’ll cry,” she warned.
”I will, I promise.”
”For real?”
”For real, for real.”
She turned to look at me, and her face lit up. “Good enough for me!”
It was the brightest smile I’d seen on her all day.

Summary:
Minoru and Chifumi initiate their first sexual encounter in the school’s guidance room, transforming their relationship into one of dominant contractor and submissive witch. Minoru uses a Mana-based ritual during climax to permanently bind Chifumi to him. They emerge hours later, exhausted and essentially bonded, setting the stage for their new power dynamic.
—
Trivia:
The guidance room is explicitly designed for Sorcery users to practice “Kansousen” (post-battle analysis/mounting sessions).
The ritual of binding involves a physical and spiritual invasion of the subject’s heart.
Chifumi’s physical change includes a magical crest appearing on her tongue as proof of the contract.
Minoru is unusually large relative to Chifumi’s anatomy, or she is particularly tight.
The school system essentially encourages these “mounting” rituals as part of the student curriculum.
Notes:
• Chifumi – Minoru’s childhood friend is a beautiful, 15-year-old high school student with a J-cup bust, long side-tailed hair, and a scrawny build. Bubbly yet sharply-tongued, she acts as his loyal, teasing confidante, negotiator, and contracted water-sorcery witch servant after a mana transfer. Despite her naive appearance, she possesses deceptive combat strength and helps scout for his dungeon group.
• Minoru – A high school student and athletic sorcery user who reincarnated with memories of a 21st-century Japanese college past into a world with reversed beauty standards. Confident and predatory, he targets slender, beautiful girls, hides his lecherous side, and asserts dominance over a childhood friend and a classmate via Mastery contracts. He is a talented squad leader building a dungeon team.
