EP.219 How to Serve as the Master's Exclusive Onahole

A posture of absolute obedience, with her head pressed to the floor and her upper body bowed as low as possible.

Her breasts were squashed like dumplings, making for a ridiculous sight.

"My body exists to make Master feel good. You can use me however you want, whenever and wherever you wish, Master..!"

"Really? Are you sure? I can use you however I want, whenever and wherever?"

"Yes..!"

In the end, a female livestock has no choice, so at least saying it prettily is better.

"I will do my best to serve Master with all my heart today as well."

"Alright, Seong-ah. Let’s see you serve with your pussy in a way befitting your status."

"Yes, Master..!"

With a sneer, Jun-ha stepped on her head and climbed onto the bed, lying down comfortably.

He placed his hands behind his head, fixed his gaze downward, and spread his legs wide to expose his groin.

"Excuse me, Master."

"Oh, wait a moment."

"Yes..?"

As she stood to perform oral service, Jun-ha handed her a pill.

"Even if you do it, you have to take this first. The real you is the one after taking this."

"Ah... yes..!"

It was the pill she had begged to take.

Now, she couldn't resist by saying she only asked because she didn't want to get pregnant.

With a foolish grin, Heo Seong-ah took the pill from her master and swallowed it.

"Ugh... uuh..."

As always, her head grew hazy and her legs lost strength.

Her lower belly tingled as if she might pee herself at any moment.

Her pussy, craving climax, contracted and relaxed on its own, dripping sticky arousal.

"Haaa..."

Lewd breaths, glazed eyes, lips curling upward.

She looked just like a beast in heat.

Unable to restrain her desire, Heo Seong-ah reached out toward her master’s erect member.

"No, Seong-ah. Don’t just start serving-beg for it one more time, okay?"

"Yes..?"

"Oh? Didn’t I tell you?"

Come to think of it, Jun-ha had always either forcefully thrust himself in or made her move her hips.

He had never made her serve in the way she wanted like this before.

"I’ll tell you. Just like when you do oral, you have to spread your holes wide and beg me."

"Ah... yes, Master..!"

It wasn’t a difficult task.

Heo Seong-ah crawled up onto her master’s abdomen as he lay on the bed.

She turned around so her lower body was most visible to him, then lifted her hips high.

She spread her buttocks wide, lewdly exposing her anus, pussy, and urethra.

"All three holes are soaking wet, huh? Doesn’t seem like it’s just the pill’s effect~?"

"Uuh..."

Before Jun-ha’s eyes was a sight rarely seen-a beautiful girl’s most intimate view.

Just a month ago, her pussy had been a tight, straight slit emphasizing her virginity; now, her labia spread wide like petals in bloom.

Ring piercings on her labia and a chain piercing through her clitoris made her look even more vulgar.

Despite this perverted pussy, her face still looked like an innocent college student.

"Nice, Seong-ah. The more you’re ruined to my taste, the more you turn me on."

"Ugh..."

A vulgar pussy that couldn’t be seen anywhere else.

Now, from this moment, she was his exclusive onahole to use for life.

The more Jun-ha thought about it, the more he was overwhelmed by an uncontrollable, sinful excitement.

Smack-

"Ahk..!"

Suddenly, Jun-ha slapped her butt hard.

With a sharp sound, her buttocks jiggled and the arousal pooled in her pussy dripped onto his navel.

"You need to beg, Seong-ah~?"

"Yes..!"

Just spreading her holes and waiting was ridiculous.

"This is a cock-hole that worked hard to make Master feel good..! From now on, I’ll use this hole to make Master feel good..!"

Perhaps because it was her first time, her answer was awkward and lacked feeling.

What mattered wasn’t such inflexible words, but how she served as a cock-hole.

Without a word, Jun-ha reached out and scratched her dripping pussy with his fingernail.

"Kk... guuuk..!"

He deliberately touched the chain piercing on her clitoris.

It sent a jolt like an electric shock.

Heo Seong-ah couldn’t help but moan and arch her back.

The wounds hadn’t fully healed, so she felt pain, but the drug’s effect also made her feel pleasure.

"How are you going to serve, Seong-ah?"

"Y-yes..?"

"You say you’ll make my cock feel good. You have two holes between your legs that can do that. Which one are you going to use?"

"Ah..."

Heo Seong-ah, who had naturally assumed she’d use her pussy, had forgotten about her anus.

She’d always kept an anal plug in and never used it because it was "dirty."

That made her even more convinced that pussy service was the default.

"I’ll make you feel good with my pussy, Master..! I’ve worked hard so I can take you all the way to the base..!"

"Really? Then let’s save that well-developed pussy for next time and use your back hole today."

"Y-yes..?"

Every time her master suddenly changed things like this, Heo Seong-ah was terrified to the point of freezing.

She didn’t know what he’d say next, but was sure it would be another scary, unreasonable demand.

"Think about it, Seong-ah. You’re supposed to serve me, right? But every time we fuck your pussy, you’re the one who feels it more and faints, right? How many times have you actually made me cum properly?"

"T-that..."

She thought about it carefully.

...

Not once.

...never.

"I-I’m sorry, Master..."

After being modified to be extra sensitive and taking the drug...

Every time his thick cock poked her cervix, she climaxed over and over, unable to control it.

Who in the world could endure such overwhelming pleasure?

"So I thought about it. The reason you can’t serve properly is because you keep orgasming. So if I use your back hole, you won’t be able to climax even if you want to, so it should be fine, right?"

"Ah... yes... th-that’s... right..."

To orgasm, his cock had to hit her cervix.

No matter how much he rammed her ass, with the rectal lining and vaginal wall separated, it was physically almost impossible for her to climax.

"So from now on, I’ll only use your back hole for service. I’ll fuck your pussy when I want to."

"W-what... you can’t just change things like that...?"

"What? What did you say?"

Heo Seong-ah was so shocked by her master’s words that she made a slip of the tongue.

"Ah, no... that’s not what I meant..."

For her, sex as "service" every night was a reward, the pleasant closure to a hard day.

After climaxing until she fainted, she could sleep soundly and feel at peace.

Even after the most hellish torture, she could endure by looking forward to the night’s reward.

But now...

If service time only meant anal, it was like being told to hang herself.

"Uuh... that’s too much..."

Not only would she lose her nightly chance at climax, but her aroused body would have no way to find release-she’d have to grind away only for her master’s pleasure.

Serving while her own feelings were completely ignored?

That was truly nothing more than being a sex disposal object.

"Seong-ah, you’re not my girlfriend yet. If you suddenly talk back like that, how am I supposed to react?"

"Ah... hhic! I-I’m sorry... but... that’s just too..."

If she’d been made to use her ass from the start, maybe it would be different...

But after a month of knowing the joy of climax, to suddenly be forbidden it-how was she supposed to live?

She already felt so miserable she wanted to cry, clutching her aching chest.

"Why? Don’t you like it?"

"It’s not that... Master... hhic..."

It wasn’t a matter of like or dislike.

Not knowing what to say, Heo Seong-ah, as always, teared up and pursed her lips.

No matter how cute she looked, Jun-ha never changed his mind once he’d decided.
