Volume 5 Chapter 9 Day One: Lock-Breaking*
Edited by: Kanaa-senpai
We froze at the sound of a visitor.
”Ye~s, opening now~”
Chifumi, who had been touching herself while watching us, quickly rose and headed for the door. Those with messy clothes fixed themselves in a hurry — Mitsuki and Asari smoothed their yukatas while I pushed myself up. There was no time for underwear, so I simply held the front closed. Once everyone looked presentable, Chifumi opened the door.
Manaka stood there.
She glanced around the room, understanding at once what we had been doing. No big reaction. She just spoke to Chifumi in her usual polite voice.
”Sorry to keep you waiting. Are you ready?”
”Of course~”
Manaka didn’t come in. She waited in the hall.
”Alright, everyone, that’s it for now. Time to swap—please clean up~”
Led by Chifumi, everyone in yukatas left the room, looking sad. My heart hurt to leave them all wound up. I will have sex with them again soon, starting tomorrow.
Sanuki-san came in next.
She too wore one of the yukatas from the cottage. As I walked to the door, Manaka spoke.
”Minoru, please take care of Megumi-san.”
”Yeah. See you tomorrow.”
”Yes, goodnight.”
”Night~”
The door shut. Outside, Manaka and Mitsuki’s voices faded.
”Hey Manaka, what’s the situation?”
”Well… I should tell Mitsuki too. Yurina-san and Asari-san, please listen if you want. Let’s talk in the living room.”
Hearing that, I turned on the Soundproofing spell again.
The noise outside died.
”……”
Sanuki-san looked tense.
Expected. From what I saw today, she didn’t seem the type to strip and jump someone.
My only memory of her from class was eating lunch with Kaharu-san. The rest came from the data Chifumi had gathered when checking for available girls before Asari joined.
”For now, strip,” I said.
”Yes…” she murmured. she replied quietly.
She likely expected that. Obedient, she took off her yukata.
She used a trick like a store clerk, folding the fabric in mid-air and laying it on the desk.
Underneath was sexy lingerie of the kind meant to tempt a man — entirely unnecessary for a simple trip. She must have expected this.
She was taller than Chifumi but shorter than Yurina, with a plump figure. There was still some fat around her belly — I would not lie, it bothered me slightly. She had hidden a lot under thick winter clothes. She looked soft to hold. Compared to my girls, her breasts were small — perhaps a C for her frame.
Compared to half a year ago, when she had carried the broad frame of a sorcerer, she had lost considerable weight. Manaka and the others must have pushed her hard.
”Everything,” I said.
”Understood,” she said.
She took off her bra and panties, folded them neatly, set them on the yukata.
”Spread your arms. Turn around once,” I instructed.
”Yes,” she answered.
I checked her from every angle.
Not for lust. To make sure she had no weapons. I trusted Manaka, but not this girl yet.
All clear. It was time for the instruction.
”Alright, let’s do this. Get on the bed, on all fours.”
”Yes…”
Still naked, she turned her back to me. I grabbed her hips, pulled her close, and stroked her soft, thick rear to adjust her position. Her belly and breasts jiggled.
”Open your legs more.”
”Like… this?”
”Good. Do not round your back,” I said.
”Yes…”
Once she was in position to receive me, I touched her crotch with my fingers. Dry, as I thought.
”Chifumi,” I called.
”Yes?” she replied.
”Suck my c**k,” I ordered.
”Sure thing~♡”
I took off my yukata and pushed my hips toward Chifumi by the bed.
She took it in her mouth, moving her lips to coat me with saliva.
I found Sanuki-san’s most sensitive spot and rubbed it gently, careful not to hurt her. Her hips twitched slightly. That seemed acceptable.
”Puhah~♡”
”Thanks, Chifumi,” I said.
”You’re welcome~” she chirped.
I pulled my hard c**k from Chifumi’s mouth and knelt behind Sanuki-san.
I put my hands on her hips, pressing the tip against her bean. Then against her lips, moving back and forth to get her ready.
”Nn… fuu… nn!♡”
Moisture started to leak from inside.
No need to wait. Easier to just push in.
I looked at Chifumi.
”Hm?”
”Hold her arms,” I said.
”Understood~” Chifumi replied.
Chifumi made ice handcuffs around Sanuki-san’s wrists.
”Eh…?!” she gasped.
She froze as her hands were caught in ice. Right then, I thrust forward.
Tight. The tip went in, but no further.
”Itt… ts…”
I gave her rear a firm slap.
”Open your legs. Push your butt out. Keep your back straight,” I commanded.
”Y-yes…” she stammered.
Once she fixed her posture, I moved forward again.
I grabbed her hips and pulled her toward me. Forced it in.
With a lot of friction, I pushed deep, my hips against her butt.
”U… ita… u…”
The words had slipped out of her.
I felt a twinge of sympathy for her, but also a surge of male pride — another first tallied.
I moved hard inside her painfully tight warmth.
”Gu… fu… nn…”
She grunted in pain but did not refuse. The sound of flesh meeting flesh grew louder and wetter. Her Strong-Female instincts caused her to produce more lubrication, easing the way.
”Ah… damn… I’m gonna release something strong.”
”Please… take care of me.”
”I’m dumping it all inside.”
About five minutes passed.
Ignoring her feelings, I only chased my own pleasure until I came deep inside her.
”Ugh!!!”
”Ku…!”
I released my seed — refined by Mitsuki and the others to hold more Mana than usual — deep inside her. I pushed hard to release everything, fighting against her tight grip. I was the one who broke, tasted, and first claimed this Strong-Female. I carved that proof into her.
Normally I would have pulled out and had her clean me. But today I tried something different.
I kept my softening c**k inside, pressing my hips against her butt with small, rhythmic motions.
Like the end of peeing, I squeezed out the rest while getting ready for a second round.
”Whew… instruction done,” I said.
”Good work~” Chifumi said.
Chifumi wiped my sweat with a towel.
We were both soaked.
Sweat beaded on the rear I was holding. Rough treatment for a virgin.
”This is where the Break-Lock begins. You ready, Megumi?”
”Y, yes… please… do it.”
Called by her first name for the first time, she looked back over her shoulder and tightened around me.
”Break-Lock” is a special Second-Push method.
”Open-Lock” is when a Strong-Female opens her own lock and shows her soul to her master, the Tsuyo-Osu. That process is led by the Strong-Female.
”Break-Lock” is the opposite — the Tsuyo-Osu forces open the Strong-Female’s lock. The lead is with the Tsuyo-Osu.
The difference lies in the outcome. With “Open-Lock,” she can open and close her lock by choice. With “Break-Lock,” her body is fully owned by the Tsuyo-Osu from that point on.
Long ago, in the era before equal rights, men of defeated sorcerer clans were killed and women were used for breeding. “Break-Lock” originated in that era. It smashes the Strong-Female’s lock, leaving it slack forever — a way to force a female’s soul under control.
You can’t just do that nowadays.
If you tried a forced “Break-Lock” on someone unwilling, you’d face social punishment, maybe war between houses. In that sense, being cut off from our houses made us lucky.
”I’ll ask just in case. Megumi, can you do an ‘Open-Lock’?”
If she could manage the Second-Push that way, it would require less effort on my part.
”…I’m sorry. I don’t think I can.”
”Understood. I’m prying it open.”
”Yes.”
I steeled myself.
My c**k had gone hard again inside Megumi’s v**ina.
I moved my hips slowly. The seed from before served as lubrication, making the way smooth.
As I kept moving, I pressed my Mana against Megumi’s lock.
”Ku!♡”
Feeling my Mana trying to reach deep inside, Megumi’s body reacted on instinct. Her toes curled. The way she tightened around me was different from before.
She had grown accustomed to the foreign object moving in and out. But now my Mana-infused invasion brought pleasure, and her body did not know how to respond.
My Mana reached her lock. Sensing my hand on it, she took a deep breath. Perhaps relaxing shifted the point of impact — her hips twitched.
”Fuuu… ah! ♡… pl, please… don’t mind me…”
”……”
Bracing for her lock to be shattered, I worked my Mana while continuing to move my hips.
My lower half enjoyed the pleasure, but my head stayed cool, doing the unlocking.
Actually, a “Break-Lock” alone isn’t that hard. With Megumi cooperating, smashing the lock by force is easier. The power gap between me, a Majin, and her, a one-limit, was clear. And her lock was already loose.
Naturally, Megumi, expecting the lock to break at once, grew suspicious when it did not.
I kept focusing on the Mana work.
I was not doing “Open-Lock” or “Break-Lock.” I was doing “Breach-Lock.”
”Breach-Lock” was when the Tsuyo-Osu crafted a duplicate key to open the lock from outside, rather than smashing it by force. To achieve this, I probed her lock, read its properties, and forged a key.
There was a reason I used this slower method.
I had feelings for Megumi. If I shattered her lock, she would have less power to refuse if another Tsuyo-Osu forced her later. I did not want a Strong-Female I had worked on to be easily stolen because of a “Break-Lock.”
If I crafted a key and performed the Second-Push via “Breach-Lock,” only I would be able to freely access her soul. My lower half burned, but my head stayed cool, focused on the task.
At the moment of my second climax, I inserted the key and twisted.
”Ah!? Ah♡… ah? Aaaaahhhhh! ♡♡”
It opened — success!
Megumi’s body shook hard beneath me, as though something deep within her had been struck. At her center, her soul was laid bare before me.
As she climaxed, her whole body convulsing, I came inside her — less than the first time, but just as strong.
Several dozen seconds passed in silence.
I swayed my hips in a daze, savoring the satisfaction of completing the difficult “Breach-Lock” while squeezing out the last drops. Her soft, slick flesh clutched at me. That virgin tightness was extraordinary.
”Hey, Minoru~? Is Sanuki-san okay~…?”
”Hm?”
Chifumi asked, sounding uncertain.
I checked Megumi. Oh, damn, she was still convulsing. Not conscious.
Right. I had left the lock open. Forgot to close it.
I closed the lock. The convulsions stopped.
I pulled my c**k out. A lot of thick sperm spilled out. Chifumi wiped it with a tissue before it hit the bed.
Without support, Megumi lay face down on the bed. A pitiful sound escaped from her. She seemed to have passed out entirely.
”Second-Push success,” I announced.
”As expected of Minoru. So cool~” Chifumi praised.
Chifumi clung to me, reaching for my c**k.
”Hey, hey…” I protested.
”…Not allowed?” she asked.
She teased my now-soft c**k, looking up at me with hopeful eyes.
”I did not say that. Spread your legs,” I said.
”Ehehe~♡”
As she opened her yukata, Chifumi was already ready for me. Her panties had vanished somewhere. I slid my now-hard c**k inside without a pause.

Summary:
The protagonist, Minoru, welcomes Megumi into the room for the training process after dismissing the other girls. He methodically proceeds to perform the “Breach-Lock” technique, which he chose over the more destructive “Break-Lock” to preserve his exclusive access to her soul. Following her involuntary climax and subsequent unconsciousness, he successfully completes the Second-Push and transitions immediately to Chifumi.
—
Trivia:
Megumi has successfully undergone a significant weight loss program under the tutelage of Manaka and others.
The protagonist specifically uses Mana-refined sperm to enhance the impact and “marking” of the Strong-Females.
Megumi’s underwear was a specific, intentionally seductive design meant for the trip.
Minoru developed genuine feelings for Megumi, which influenced his decision to use the more precise “Breach-Lock” instead of the damaging “Break-Lock.”
