Volume 3 Chapter 18 Interlude: End of Summer Vacation*
Edited by: Kanaa-senpai
Summer vacation is almost over.
Which means the second semester is starting. I’m not worried about my academics.
The problem is, as expected, dungeon exploration.
I don’t expect to be suddenly assigned a high-difficulty dungeon involving life-or-death stakes, but I want to experience large-scale combat to enter the practical sessions smoothly.
I really need to make good use of the daily dungeon at Risa’s house.
I toss some feed into the water tank.
As usual, Tempura is munching away.
Thinking a part of the sand had moved, Clams poked his head out, wiggling about.
I named this Clams, Clam. When materialized, he’s treated as a mascot by my family and the group, who all call him “Clam-chan.” Minoru’s younger sisters, in particular, rate him highly. They say he’s cute, like a doll. A foreign-sounding name with the appearance of a traditional Japanese doll. It’s unbalanced, but that’s fine too.1
Usually, the rule was for him to live in the water tank as a bivalve and be summoned only when necessary… but Yui-kou has been letting him turn into human form to play whenever she likes. She must be happy to have gained the power to move freely on land. I had no choice but to allow him to leave the annex as long as he stayed on the property and was accompanied by his instructor, Tempura. Ever since, a little girl with a shrimp on her head has been popping up around the house.
”Morning~” Chifumi greeted.
”Good, morning…” Asari added.
Chifumi and Asari arrived.
”Man, it’s ho~t. I’m drenched in sweat just from walking here~” Chifumi complained.
”It’s already almost September, yet the late-summer heat is still so brutal…” Asari sighed.
The two cooled off as they entered the air-conditioned room.
”Sorry to make you come all this way, but we’re heading to Risa’s house in a little bit,” I informed them.
”Eh~!?” they both exclaimed.
”I want to rest a little more…” Asari muttered.
I toss the ice cream I took from the freezer to the two of them as they voice their dissatisfaction. Nice catch.
”Eat this,” I commanded.
”Thanks~” Chifumi chirped.
”Thank you,” Asari said.
The two obediently began munching on the ice cream.
It’s an ice pop, not milk-based ice cream. I keep the calorie intake as low as possible even with things like this.
”I’m coming back to life~♡” Chifumi exclaimed.
Chifumi says with a satisfied expression, fanning herself by pulling at the collar of her shirt.
Seeing the cleavage exposed so defenselessly, I felt a bolt of electricity run through my brain.
”Ah————!!!!” I shouted.
I let out a cry before I could stop myself.
The two jumped as if my internal electrical current had been transmitted to them.
”Wh, what? What’s wrong~?” Chifumi asked.
”Minoru-san, are you okay…?” Asari inquired.
”Swimsuits!” I declared.
I stared into their eyes and told them clearly.
”I thought I was forgetting something. Swimsuits. We haven’t done swimsuit hanky-panky!!”
Chifumi looked at me with an expression of disbelief. Asari looked confused.
”Minoru~? Swimsuits are for swimming. They aren’t costumes to get you in the mood for hanky-panky~?” Chifumi countered.
”You were the one wearing the most lewd swimsuit of all. Who are you to say that?” I retorted.
Asari nods at my observation.
It seems that, even from a woman’s perspective, Chifumi was being erotic.
”Since you haven’t said anything about swimsuits since we got back from the island, I thought maybe you weren’t that excited by them anymore, Minoru~” Chifumi teased.
”Me too…” Asari whispered.
”Gu. When you put it like that, I feel like I missed the timing… But I won’t give up. I’m a man who does what he says he’ll do!” I insisted.
On the island, I acted as rationally as I could.
I didn’t call anyone over during our free time at night, and for the full week—five days of the island trip plus two days of travel—my desires kept building up. There’s also the excuse that the latter half was too chaotic due to the incidents.
When the group gathered together after returning from the island, I didn’t stop until I had emptied everything out.
At that time, it wasn’t so much that I was excited by swimsuits, but rather a mental state where I was excited by anything.
The kind of state where even a tree hollow looks erotic. I prioritized everyone getting pleasure together over making them change into swimsuits. Only after I had left everyone’s bellies sloshing with my seed did I finally calm down, and since then, things have returned to normal.
”Are you really going to do it~?” Chifumi asked.
”I’m doing it!” I affirmed.
”You know~ there’s no need to do it as a duty right now? If Minoru wants it, I’ll wear a swimsuit for you even in the dead of winter~” Chifumi offered.
I’m happy to hear Chifumi say that. Asari nods along with Chifumi while licking her ice pop. It’s somehow erotic…
”…”
Perhaps noticing my silent, fixed gaze, Asari sticks out her pink tongue and licks the ice cream in a way that shows it off.
”Wait, wait~~~? No jumping the gun allowed!” Chifumi snapped.
Noticing my gaze as well, Chifumi stands up with force, blocks my line of sight, and starts getting angry.
”I’ve decided~. Today, I’m going to squeeze Minoru dry in a swimsuit. I won’t let you off even if you start squealing~. I’ll keep going until you’re completely drained~” Chifumi warned.
”Oh, for real?” I asked.
”For real, super real~” she confirmed.
Asari, having finished her ice cream, joined in too.
”I will serve you in a swimsuit too… okay♡” Asari promised.
”Umu,” I replied.
Now I have confirmation from both of them. All that’s left are the two who aren’t here. I can just talk to them when we get to Risa’s house. I stare blankly as Chifumi and the others take their swimsuits out of the chest of drawers.
We’ll be back in the evening, so we finish up various preparations and head out.
Training at Risa’s house.
Recently, I’ve been increasing the number of oddities that appear. Today, I’m challenging nine of them.
Nine butterflies, nine weasels, nine sparrows. We carried out combat against each group.
It gets difficult immediately if the enemy oddities have long-range attack capabilities.
If Chifumi’s anti-group attack sorcery hits properly, we can win smoothly.
Conversely, without Chifumi’s support, the situation falls apart. We don’t lose, but it takes a considerable amount of time. Yurina, Risa, and even I lack experience in anti-group combat.
It was much easier to exorcise the [Anatomical model] I designated as the boss oddity.
I really need to do something about my sorcery and techniques for anti-group battles…
Leaving the dungeon, we returned to the house with Risa and the others.
Of course, I had them bring their swimsuits.
Today, we made it a rule to spend our time in the house in swimsuits.
Everyone’s swimsuits were the same ones we saw at the beach. To get in the mood, I changed into a swimsuit too. My outfit is a T-shirt on my upper body and trunk-type swimsuits.
When everyone is spending time in swimsuits, Clams materialized and stared at us with a curious expression. He seemed like he wanted to say something, but I didn’t answer and forcefully turned him back into a bivalve and threw him into the water tank. For now, just be quiet in there with Tempura.
While Chifumi and Asari were making dinner, I held Risa and Yurina in my arms and engaged in some light play.
Specifically, rubbing against their n**ples through the swimsuits and having them fondle my crotch.
It feels luxurious to wastefully do this on [Leisure sheets] spread out over the tatami mats instead of on a [futon].
Risa and Yurina, who are clinging to me from both sides, are wearing black and red bikini-type swimsuits, respectively.
It’s a design that seems to suit them both: a slightly aggressive black, and a modestly shaped red.
I could tell their n**ples, which had become stiff and hard, were pushing up the swimsuits. Without a word, I thrust my hands under the swimsuits and lightly pinched the hardened nubs.
”Nn…♡” Risa gasped.
”Fah…♡♡” Yurina sighed.
Both of them reacted.
As if to say, “This is in return,” they thrust their hands under my swimsuit.
Risa grabbed and rubbed my male member, and Yurina kneaded and rolled my balls. Their service techniques have also improved. Without a word, they used only their gazes to divide the roles and attack me. It’s what you call perfect synchronicity.
My son reached a full erection immediately. My sensitivity was rising. If I exploded like this, it would be a disaster inside the swimsuit.
When I lifted my hips slightly, the two understood my intent and took off my swimsuit.
I operated them while pinching their n**ples, then had them face each other with Risa on bottom and Yurina on top, making them spread their legs.
Two swimsuits lined up vertically. When I shifted the crotch area, the slippery [Secret cave] appeared.
First, Risa on the bottom.
I pushed in with a shove, as if splitting her flesh apart.
The same tight, fleshy welcome as always. My sensitivity heightened all at once.
I pushed in and thrust three times, as if slamming into her, then pulled out. Watching my member coated in Risa’s nectar, I shifted the tip upward.
Insertion into Yurina requires preparation and a rubber. It’s impossible at this stage.
And so, I inserted my member between the two women’s [cunt]s, moving it so it would be rubbed by both top and bottom.
I was careful to go back into Risa occasionally so that my member wouldn’t dry out. Sometimes, I would rub it strongly against Yurina’s [cunt] to coat it with Yurina’s love nectar in a pseudo-thigh-s*x fashion.
For the two of them, I think the pleasure was at a frustrating level, but my sensitivity was rising steadily.
The sound of our hips slapping together got louder and louder, and I reached my limit.
”Both of you, c*m!” I shouted.
”っ…一回目っ♡♡♡” Risa shrieked.
”大好きですっ♡♡♡” Yurina confessed.
The two stiffened.
I, caught between them, also crossed my limit, my first e**culation during swimsuit hanky-panky.
I pulled my son, who had e**culated between the two, out and brought him near their faces, and the two cleaned him up with their tongues.
”はぁ…♡” Yurina breathed.
”ん…たくさん…出ましたね…♡” Risa whispered.
Yurina slowly sat up and began to lick the s**men off Risa’s swimsuit. Once it was clean, Risa conversely began to lick the s**men off Yurina’s swimsuit.
”私も, 準備して来ましょうか…? ” Yurina asked.
”それは後. 先にご飯たべよ～” I decided.
Just as Yurina was about to start preparing her bottom, Chifumi returned from the kitchen. An apron over a swimsuit is also a nice, non-routine look.
On the tray were [Rice balls], [Tamagoyaki], and [Sausage].
The lineup felt like a bento box. They must be trying to give it a beachy vibe even through the meal menu.
”Minoru~ほら, あ～ん” Chifumi said.
”ん…” I replied.
”どう～? おいしい～?” Chifumi asked.
”うまい” I said.
”Minoru-san, こっちもどうぞ” Asari offered.
”ん…” I murmured.
Both sides of me were yielded to Chifumi and Asari, and the two fed me.
Since we have such a nice situation, I don’t forget to play some mischief.
I don’t want to waste the food, so I repeat mischief with an appropriate amount of moderation.
”もう～…メッ…♡” Chifumi scolded.
”だめですよ…ん♡” Asari protested.
The girls were surprisingly willing. The way they show a moderate amount of resistance, they understand me well.
It’s more exciting when they resist a little, you know.
When I was full, I pushed Chifumi down onto the [Leisure sheets].
Just by shifting her swimsuit slightly, the tip popped out, plump. The lack of fabric was working against her.
The delicious-looking pink cherry is my own personal dessert. When I suck on it, I feel like I can even taste a faint sweetness.
Risa and Yurina are in charge of cleaning up.
After confirming I had begun fooling around with Chifumi, she took the dishes and disappeared into the kitchen. The remaining Asari pressed her body tightly against my back.
I had Asari remove my swim trunks, then inserted my fully erect ‘son’ into Chifumi.
I parted her secret folds with my glans and pushed inside, coming to a stop when I reached that slightly different, sensitive spot deep within.
”Hau…♡” Chifumi sighed, her voice soft and bubbly like a sweet daydream.
With a wet, squelching sound—guchu—my hips and Chifumi’s locked in rhythm.
Ah, it feels so good. As expected of my head Majo.2
”So nice…♡” Asari whispered, her tone carrying the airy, excited lilt of a girl completely head-over-heels.
Asari, clinging to me from behind, whispered sweetly into my ear. Don’t worry. I’ll make sure to fill you up properly later, too.
As I began to move my hips, the leisure sheet rustled with a harsh, dry sound—gasagasa.
The wet sounds, the dry friction, and our ragged breathing. The atmosphere is fantastic. The pleasure signals rushing from my c**k up through my spine are magnificent.
There was no way I could hold back, so I thrust with wild abandon, riding the wave to the peak in one go.
Chifumi, even without a command, convulsed her body in time with my e**culation. It seems she’s become able to climax in sync with me. This is the nature of our Majin and Majo relationship.
I poured a generous amount of seed and Mana deep inside, then slowly pulled away.
Watching my s**men overflow from within Chifumi—toro—I rolled Asari over next to her.
I slid down the shoulder straps of the competitive swimsuit Asari was wearing to bare her breasts, then shifted the fabric at her crotch to the side and entered.
”Nn…♡…nnn♡♡” Asari squealed, her voice breathless and giddy.
With Asari, it’s a kiss-humping session in the missionary position.
I forced my way to the very end without once breaking our lip-lock.
”Nnn…♡…nnnnnn♡♡♡” Asari whimpered, her voice fluttering with delight.
Perhaps she’s struggling for air, as she’s tensing up. The tightness of the hole enveloping me naturally increases.
I focused my assault on the rougher patch inside Asari. I could feel her arms wrapping around my body, her nails digging into my back.
Using that slight pain as a spice for my excitement, I changed my hip movements to be larger and more powerful. I concentrated entirely on making Asari feel good.
”Nnnnnnn!! ♡♡♡” Asari cried out, her voice peaking with pure, sugary intensity.
As she convulsed beneath me, leaking her fluids—pyuru pyuru—I reached my third e**culation of the day inside Asari.
When I slowly pulled away, the white liquid dripped from between Asari’s thighs.
”Aa-! Geez! You saved some for us, right!?” Asari pouted, her words tumbling out with a playful, trendy edge.
”I will prepare it immediately, so please wait.” Risa replied, her voice crisp, calm, and perfectly composed.
Risa, having finished cleaning up, returned from the kitchen and clung to me, while Yurina disappeared into the toilet to prepare for our union.
After that, I dealt with the four of them. Much like a certain phantom thief, I moved between them all, thrusting my hips.
When I became tired, they laid me on my back and milked me dry while riding on top. Just as Chifumi had declared, I was squeezed dry in their swimsuits.
By the time the day turned, they had all fallen asleep, exhausted.
Alone, I stared up at the dark ceiling and thought.
I am satisfied with their serviceability, but something is missing.
This summer, I realized I had been vaguely aware of this snag all along.
I didn’t want to let Manaka and the others—my childhood friends—go.
I made excuses to myself, saying I had been abandoned, and watched politely as they drifted away from me.
But when I dreamt that Yui and Yuu had died, I felt an incredible sense of loss. The despair I felt when I thought even Manaka had been killed by the apparition was no less intense than the emotions I felt when I thought Risa, Yurina, or Asari had died.
Fortunately, that was just a dream, but…. Suddenly, imagining them becoming the property of some other ‘Tsuyo-Osu’ (Strong-Male) makes my chest ache unbearably. I want to make them all my Majo. I don’t want to give them to anyone. I want to pin them down, make them whimper, and force them to submit beneath me.
My ‘son,’ which should have been fully drained, began to regain its strength.
”Nn…Minoru…? What’s wrong~?” Chifumi murmured, her voice sounding sleepy and delightfully charmed.
When I ran my hand through Chifumi’s hair, she opened her eyes, realized I was awake, and spoke to me.
”…One last time, is that okay?” I asked, my voice steady and measured.
”Ah…nn♡…It’s fine. Go ahead and finish until you’re satisfied♡♡” Chifumi cooed, her tone light and infatuated.
Although Chifumi looked sluggish and limp, she opened her legs languidly when I attempted to ‘re-unite’ with her.
Deep within the warm, pleasant, sludge-filled depths of Chifumi, I had my final release of the day. This is the absolute, dry-to-the-bone, last of it.
”Ah…feels good…it came out…” Chifumi sighed, her voice drifting into a blissful haze.
”Nya…hafu…♡” Asari murmured in her sleep, her voice a tiny, dreamy chirp.
”Nn…thanks, Chifumi. I love you.”
”I love you too~…Are you satisfied~?” Chifumi whispered, her voice bubbling with affection.
”Satisfied. I have no regrets…”
”Nn…♡♡”
After a light kiss, I buried my face in Chifumi’s voluminous chest. Held in her embrace, being stroked and comforted by her, my field of vision began to narrow. I’m getting sleepy, too. My eyelids are heavy.
Tomorrow is the last day of summer vacation.
Once we spend it relaxing, the second semester will begin.
I hope I can spend the second semester safely with these girls, too.
Chapter 3 end.
Chapter 4 will be about the second semester. A transfer student is scheduled to arrive…
Thank you for your support.
