For several days, only Skeleton Wraiths appeared in the dungeon.
After my mana capacity exceeded 15, our trio's lifestyle fell into a certain pattern.
First, after waking up and showering in the morning, I would grab either Zoe or Lucy and have sex with them.
"Let's increase our mana before we go out."
Since the purpose was to increase mana capacity rather than charging, it didn't necessarily have to be internal ejaculation.
"Shall we?"
Zoe was always compliant.
"What difference does 1 point make? Hnngh!"
Lucy would play hard to get a little.
After preparations, we'd set out to conquer the dungeon.
When mana ran low, I'd absorb it midway.
Usually, I'd have them lean against the dungeon wall, sticking out their butts side by side.
"Ikan, I'm, I'm cumming♥"
If they climaxed while I was thrusting, I'd move to the other one and repeat.
"Lucy, I'm going to cum."
"Ugh! Go ahead."
With their top-tier pussies, 30 minutes was enough to cum twice.
After clearing the morning dungeon, we'd set up camp in a safe zone.
We'd immediately start having sex with internal ejaculation to charge mana.
I'd cum inside them alternately, and once mana was fully charged, we'd have lunch together.
After lunch, we'd chat over tea or play board games set up at the camp.
We'd take naps or have personal maintenance time.
After sufficient rest, we'd run the afternoon dungeon.
If we arrived at a new safe zone before 6 PM, we'd set up camp.
We wouldn't leave the safe zone at night because dungeon monsters get stronger and unexpected events occur more frequently.
We'd eat dinner, rest, and then have sex to charge mana for tomorrow's dungeon run.
With nothing else to do, we'd usually just have sex until bedtime.
Even if mana was full, we'd continue with the purpose of increasing mana capacity.
Four days passed like this.
After my morning shower, I checked my mana level.
[Mana: 30 / 31]
I dried off and used a hairdryer.
When I came out of the shower, Zoe and Lucy were chatting in their underwear.
It had become an unspoken routine to wait in underwear to avoid getting semen on battle gear, which was hard to wash.
"Oh, right. There. It's really delicious."
"Sis, you know that place too? Let's take Ikan there when we get out of the dungeon. He's probably never been there, being a loner and all."
"Where?"
I came to the table, swinging my huge dick after showering.
Lucy glanced at my dick and said,
"There's a snack shop in front of the academy.
They have really delicious cheese tteokbokki."
"Really?"
[Co-come to me, Ikan. I'll suck hard. I can do better than yesterday. Please.]
I went to Zoe.
She naturally got down from the table chair and started sucking my dick.
Slurp. Slurp.
While stroking Zoe's head, I asked,
"Do you both like tteokbokki?"
Lucy said,
"You don't? Well, I guess boys don't really like tteokbokki. They prefer things like pork cutlet or spicy pork, right?"
"Slurp. Ikan, do you like spicy pork?
I know how to make it.
Should I make it for you when we get back to the academy?"
Zoe looked up at me.
"That's unexpected. You know how to cook?
Zoe, what do you like?
Tteokbokki too?"
"Me? Um... I-"
[Ikan, the morning semen you cum for me♥
Cum in my mouth. I'll swallow it all.]
She pretends to answer casually.
"I guess... Korean food? Like kimchi stew?"
Then she puts my dick back in her mouth and moves her head vigorously.
"Lucy, what about you?
What do you want to eat most right now?
Tteokbokki again?"
"Well."
Lucy shrugged nonchalantly.
[Lucy]
[Status: Aroused]
[The precum that comes out when I suck your dick♥
What should I do? I'm going crazy. Just thinking about it makes me wet.
Tell me to come and suck it too, Ikan. Please.]
"Zoe."
"Mmm?"
Zoe looks up at me with her mouth full of dick.
"Put it in deeper."
"Mmmm."
The thick dick goes deeper into her mouth.
She sucks hard, tightening her throat around my dick.
"That's much better. I think I'll cum faster today."
A little while later, I took Zoe to the bed and came inside her, then we started our morning dungeon run.
***
We set up camp in the safe zone we arrived at in the afternoon and took turns having sex with internal ejaculation to charge mana.
After lunch, we had personal maintenance time.
After taking a nap, I walked around the safe zone once and returned to the camp.
"Lucy, what are you doing?"
"Huh? Playing a game. Why?"
She was lying on the bed playing on her phone.
It looked like a simple game that didn't need internet connection.
With enough power supplied by the magic stone, charging phones wasn't an issue.
"Let's do it once before we go out."
I took off my clothes and got on the bed.
"We just filled up earlier."
Lucy, who was lying down, got on her knees and presented her butt to me.
"To increase mana capacity."
I pulled down her panties and rubbed my huge training dick against her pussy lips.
I pushed my fully erect meat stick into her quickly wet pussy.
"Ahh."
She inadvertently moaned, focused on her game.
I grabbed her firm buttocks and started moving my hips.
Squelch squelch squelch
Love juices dripped onto the bed sheet.
I peeked at Lucy's phone screen over her shoulder.
"What game is it?"
"Just a puzzle game I play to kill time.
What's sis doing?"
"Training skills outside."
I rotated my hips, stirring her insides with my dick.
"Haa. Aahn♥"
Lucy put down her phone.
"It's good that my dick is big, right?"
"What are you saying."
"Take off your top."
Lucy obediently took off her sweatshirt and bra while being fucked from behind.
I pulled her arms to raise her up, then grabbed her large breasts with both hands.
"You really like my breasts, don't you?"
"I do."
I circled both nipples with my index fingers.
"...Really?"
"I'm being honest like this.
Why don't you tell me you like my dick?"
"Is that the same?"
Slap slap slap slap
I started thrusting my dick faster.
Her ass bounced and the bed creaked.
Lucy couldn't help but throw her head back.
"Ahnnggg♥"
"Say it. Say you like it."
Slap slap slap slap
"Aaaahn."
"Hurry."
"I like it. I'm doing this because I like it. Haa. Aahn♥"
The huge training dick always wins.
"From now on, tell me you like it, okay?"
"Ikan, you're really annoying."
I pulled my dick out of her pussy.
"Turn around."
Lucy turned and lay down in front of me.
She grabbed my dick on her own and licked the tip.
"Suck it."
She started sucking slurp slurp.
"Gulp. Mmm."
Her head moves vigorously.
"Slowly. Suck slowly."
Lucy tried to take my dick deeper into her throat than Zoe did this morning.
Her saliva ran down my shaft and dripped onto the bed sheet.

Late at night.
The camp was quiet with the lights off.
Just as I was about to fall asleep, I sensed someone.
It was Lucy.
"Shh."
She climbed onto the bed naked.
I whispered in a low voice,
"What is it?"
"Were you asleep?"
She also whispered, coming close to me.
"No. I was just about to sleep."
Lucy smiled mischievously and put her hand inside my underwear.
"Want to do it again?"
We did it plenty after dinner.
She stroked my erect dick with her hand and whispered in my ear.
"I like your dick."
How can I refuse after that?
We kissed quietly, trying not to make noise.
But we couldn't completely hide our hot breaths and the sound of sucking each other's lips.
Unable to hold back, she climbed on top of me.
She aligned her hole with my fully erect dick and lowered her hips.
She covered her mouth with her hand.
Slap slap slap
She started bouncing on top of me.
I teased her nipples with my fingers and said,
"Be quiet. Zoe's sleeping."
"Mmm. Okay."
Lucy started moving her hips slowly.
Then-
Suddenly, Zoe's voice came from the opposite side in the darkness.
"Go to sleep, kids. I'm saying this as your instructor."
Lucy laughed and cleared her throat.
"Ahem. Sis, we'll sleep after this."
Now she bounces vigorously without hiding her voice.
Slap slap slap slap
"Aahn♥"
A moment later, the bed curtain was pulled back.
It was Zoe.
"Let me join in too."
The lights in the camp turned on.
"Slurp slurp suck."
"Sis, it's my turn now, okay?"
I lay on the bed while Zoe and Lucy took turns sucking my huge upright dick.
I came inside them alternately until late into the night.
[Mana: 38 / 39]

The next day.
The safe zone we arrived at around lunchtime was different.
There was a small hole in the dome-shaped ceiling, and sunlight was pouring through it.
I looked up at the ceiling in awe.
"Wow. It's been so long since we've seen sunlight."
"Ah, it feels good. Sis, come quick and get some sun too."
Zoe was closely examining the wall of the safe zone alone.
She beckoned to us.
"Guys, come look at this!"
"What? What is it?"
Her voice sounded urgent, so we ran to her, forsaking the sunlight we hadn't seen in days.
There were unknown characters written on the wall.
It was translated for me and appeared as a notification window.
[Dungeon Progress: 48%]
Zoe had seen the same thing with her status window skill.
Lucy and I, after hearing what was written, jumped for joy.
The times of despair, not knowing when this would end.
The fact that future-guaranteed super-beautiful S-rank hunters and hunter aspirants mixed bodies with F-rank me was partly because my body felt good, but also a desperate struggle to overcome the hopeless situation of our minds falling apart.
Now the situation has changed.
We have hope.
"We've been too focused on dungeon conquest without any productivity.
From now on, let's train in the evenings.
We can't fall behind when we return to the academy."
Zoe spoke like a proper instructor for once.
"Let's do one more set. Come on, keep it up!"
After dinner, we did physical training.
"Ikan. Thrust and twist. That's right. Like that."
Lucy and I received combat training from Zoe.
After training, we learned mana manipulation methods and basic magic from Lucy, who specializes in magic.
"Concentrate. You need to clearly visualize the image in your mind."
After completing combat and magic training, washing up, it was now my turn to be the instructor.
"Zoe. Lower your hips more. Tighten your pussy more when I try to pull out my dick. As if you're trying to prevent me from pulling out.
Don't just passively get fucked. You need to match my rhythm too."
It was time for training to make me ejaculate as quickly as possible to efficiently charge mana.
In other words, it was combat sex time.
"L-like this?"
"That's right. Good."
Slap slap slap slap
I thrust my dick relentlessly from behind.
"Aaaaaahn♥"
"How is it? Feels much better, right?"
"Yesss. So gooood. Heck. Heck."
"Next. Lucy, let's try."
"Okay."
The real training began.
