The next morning.
Lucy was lying face down on the bed with her hips raised, and Ikan's huge dick for training was inside her.
I gathered her arms behind her back.
"Hey. Pull it out. Won't you?"
Lucy resisted, but it was useless.
I was pressing down on her body tightly.
"I don't want to."
The thick shaft slowly entered her like a piston.
"Nngh!"
I started the morning piston movement in earnest.
Squelch squelch squelch
Slowly, slowly, I violated her, scratching her inner walls.
"Ahh. Aaahn♥"
"Lucy.
Is that something to get so angry about?
You're my semen receptacle, right?
I don't understand why you keep getting angry at the truth?"
"You... you don't do this to sis Zoe and always do it to me on purpose!"
As the dick entered her hole, her juices dripped out from the pressure.
"Why are you two fighting again so early in the morning? Hm?"
Zoe put water in the coffee pot.
"Sis. He keeps calling me his semen receptacle."
"Ikan. Don't call her that."
She gently admonished me.
I joked around.
"I'm just kidding. She's fun to tease, so I want to keep bullying her."
Lucy struggled under me.
"Ugh. You, when we get out of the dungeon—"
"What will you do?
Leave a review saying it was the best dick ever?"
"Are you crazy?"
"Then are you going to leave a bad review? Ah. That won't do.
Customer, I'll give you some semen as service, so please leave a good review."
I started thrusting my dick in quickly.
Slap slap slap slap
Lucy's eyes rolled back as she was fucked.
"Aaahn♥ Nnngh."
She bit down on the blanket next to her, trying not to moan.
[He's crazy. Ikan's dick is the best♥
I like how we banter like this too.
I wonder if we can keep this kind of relationship even after we leave the dungeon?]
"Lucy. If you take this, you'll become my semen receptacle, okay?"
"Mmph. Mmph!"
"I'm cumming. Ahhh."
I started ejaculating large amounts of semen into Lucy's pussy.
[Mana: 48 / 49]
Every time I thrust my dick, white semen flowed back out of her like a pump.
***
My mana had increased.
We adjusted our daily pattern.
In the morning, we used up the mana we had fully charged the previous day to rapidly progress through the dungeon.
When we found a safe zone around the time our mana was depleted, we set up a base camp.
In the afternoon, we only had sex to recharge mana.
On the bed.
I gave Zoe missionary style thrusts, and soon her waist arched.
"Ahhhn♥"
When I pulled out my dick, her pussy squirted vertically.
I asked Lucy, who was watching from the side.
"How many minutes?"
Lucy checked the timer she had been keeping on her phone.
"3 minutes 28 seconds."
I rubbed Zoe's wet clit with my hand as she was cumming.
"Wow. Zoe used to not even last 3 minutes. You've improved a lot."
Zoe just twitched her hips, panting heavily.
"Lucy's turn next."
"Okay."
Lucy lay down next to me and spread her legs.
I burrowed between her legs and started inserting my dick familiarly.
Squelch squelch squelch
"Ikan. Was what you said earlier true?"
"Of course."
"If I last longer than sis, you'll really exempt me from bathroom cleaning?"
"Yeah.
But while Zoe cleans, you have to clean my dick with your mouth."
"Well, I do that every day anyway."
"Right. Then let's see how long you can last."
Slap slap slap slap
I continued thrusting vigorously.
"Ahhhn♥"
Since there was nothing else to do at the camp, competing for time with sex became our entertainment.
Evening.
Time for battle sex.
Zoe and Lucy were lying face down side by side towards me.
I put the dick Lucy had just been sucking in front of Zoe's mouth, and she naturally took it in and started sucking.
I caressed Zoe and Lucy's cheeks.
Lucy rubbed her cheek against my hand as if in a dream.
An imaginary figure asked me a question.
[Tell me, which bitch gives better fellatio?]
'They're both excellent. They both know how to tighten their throats around my dick, and they keep sucking without stopping even when I ejaculate two paper cups worth of semen in their mouths.'
[Come on. There must be one that's a bit better.]
I approached the imaginary figure and whispered.
'Actually, the one with black bob hair is a bit better.'
I grabbed Zoe's head and pushed my hips forward.
"Ack."
My dick went straight to her throat.
"I'm cumming? You can take it, right?"
"Ack."
Zoe blinked up at me.
[Ikan's semen. When it's forcibly injected into my throat like this, I'm... going to cum again♥]
The veiny huge dick throbbed visibly.
I ejaculated directly into Zoe's throat.
"Ack."
Gulp. Gulp.
Zoe's eyes rolled back.
She started squirting pussy juice uncontrollably onto the bed sheets, her hips shaking.
I stroked Zoe's head.
[But why are you speaking so quietly?]
'Because the blonde bitch would get jealous.'
Lucy watched Zoe cumming from the side, rubbing her cheek against my hand.
[Bitch.]
I brought my thumb to Lucy's mouth.
She sucked on my finger, slurp slurp.
[Wait. What am I thinking?
Lucy. That's sis Zoe.
It's not fair that she knows how to do things like that.
...It's okay. I can make Ikan cum faster with my pussy.]
After I finished cumming, the huge dick slipped out of Zoe's mouth.
I put my dick between the two of them.
Zoe and Lucy licked my thing amicably.
***
A few days later.
One lazy afternoon after lunch, I went for a walk around the safe zone and returned to camp.
Zoe was sitting at the table writing something.
I went and sat down next to her.
Zoe covered the paper she was writing on with both hands.
"Where's Lucy?"
"She's swimming in the lake and sunbathing.
What were you doing?"
"Just..."
"What is it, what is it?"
Zoe said shyly.
"We're already 80% through the dungeon.
So... I was writing down things I want to do when we get out."
Her cheeks turned red.
"Can you show me?"
"..."
Zoe silently shook her head.
I moved my chair right up next to hers.
Zoe's hands didn't move from on top of the paper.
I unzipped her tracksuit.
Her breasts were exposed, with no underwear.
I tickled her pink nipples with my fingers.
"Mmm. Don't..."
Zoe still didn't seem to have any intention of taking her hands off the paper.
I said to her.
"When we get out of the dungeon, you'll be an instructor for S-rank people and I'll be F-rank, so we probably won't see each other much."
"I-is that so?"
"Will our relationship... go back to being nothing?"
We stared into each other's eyes from up close.
I caressed her cheek.
"Zoe."
"..."
"I like you."
Our lips got closer.
We kissed.
Zoe reached between my legs and stroked my dick under my pants.
Blood rushed to my lower body.
I took off my pants and sat back down on the chair.
My huge dick stood up vertically.
"Come here."
Zoe flipped over the paper.
"Don't look. Okay?"
"Okay."
She took off her clothes and climbed onto my lap naked.
She grabbed my dick and lined it up with her pussy hole, then lowered her hips.
"Ahh."
As my dick slid in, Zoe looked at me with a flushed face.
I took her arms and twisted them behind her back, then held them with one hand.
"Ugh."
Zoe couldn't move with the huge dick inside her and her arms restrained.
Her pink nipples visibly perked up right in front of my eyes.
"Now's my chance."
I checked the paper Zoe had written on.
Though I thought she would struggle, she just blushed and stayed still.
Things to do when we get out of the dungeon♥
"Try popular restaurants"
"Movie date"
"Go to dessert cafes together"
"Coin karaoke too!"
"Apply to be an F-rank hunter instructor"
…
….
…..
As I finished reading the list, Zoe said.
"...Want to do them together?"
I put down the paper.
Zoe avoided my gaze.
Her face had turned bright red.
I pinched her perky pink nipple with my fingers.
"Nngh!"
"I told you I like you. I still haven't heard your answer."
Zoe gently moved her hips.
"I like Ikan's dick."
"Just my dick?"
"...I like Ikan too."
I let go of her nipple.
"I love you, Zoe."
"M-me too."
"Me too what?"
"...I love you."
"Besides what's written here.
Is there anything you want to do with me right now?
Anything you want me to do?"
Zoe bit her lower lip.
[I wish he'd call me his semen receptacle like he does with Lucy.
I want to be degraded as Ikan's semen receptacle♥
But... if I say it honestly.
Will he think I'm a pervert and lose interest?]
Smack!
I spanked her ass.
"Ahh!"
Zoe's waist arched like a bow.
A red handprint bloomed on her pale buttock.
"If you love me, tell me honestly what you're thinking right now."
"..."
Smack!
"Ahhn♥"
"Say it."
"Semen receptacle..."
"Hm? I can't hear you."
"Call me... your semen receptacle like you do with Lucy."
"Okay."
When I said "Okay," her inner walls clenched tight.
"Hug me."
I let go of Zoe's restrained arms.
She wrapped her arms around my neck.
I put my arms under her knees and stood up from the chair.
"Mmh."
She was now in a carry fuck position.
Zoe hugged me tightly.
I whispered in her ear.
"Zoe. From today, you're my personal semen receptacle. Got it?"
"...Yeah."
The huge dick started moving in and out of her pussy.
"Ahhn."
Her juices flowed down my shaft and dripped from my balls onto the floor.
"What are you to me?"
"Semen receptacle..."
I started thrusting quickly in the carry position.
Slap slap slap slap
"Nnngh!"
"Answer properly."
Zoe answered again.
"I'm your semen receptacle. Ahhhn♥"
"Is that all the volume a hunter academy instructor can muster?"
"Hnngg."
"Repeat after me: I, Zoe, am Ikan's personal semen receptacle."
"Mmm. Ikan..."
"You think I'm joking?"
I started thrusting hard enough to make loud slapping sounds.
"Ahhn. Ahhhn."
"Hurry up and say it."
"I, I Zoe am Ikan's personal semen receptacle."
"Louder."
Slap slap slap slap.
The piston movements got more intense.
Zoe threw her head back and cried out like she was moaning.
"Ahhn♥ I, Zoe, am Ikan's personal semen receptacle!"
Slap slap slap slap.
"Again."
"I, Zoe, am Ikan's personal semen receptacle!"
"Louder. So Lucy can hear."
"I, Zoe, am Ikan's personal semen receptacle-aahhhn♥"
Twitch! Twitch!
Her hips convulsed like she was twerking.
Pussy juice squirted from where we were connected.
"You lewd semen receptacle."
The slapping sounds echoed non-stop throughout the camp.
