Breathing Life into Real Dolls

1.

Serena immediately stripped off Kim Doha’s pants and underwear. The penis that was revealed looked small, as it was not yet erect.

“Now, Ciel. This is what the penis looks like before it gets big. Take a look.”

“Yes.”

Ciel adjusted her eye level to Kim Doha’s penis and observed it closely.

Contrary to the firm and majestic appearance during sex, its current soft appearance stimulated Ciel’s heart.

‘It looks so vulnerable; I want to protect it…’

Ciel, who was observing the penis, detected a sweet smell. She found the source of the scent and sniffed at Kim Doha’s groin, pressing her nose to it.

“Hmm… Something smells sweet…”

“Already? It’s the smell of Master’s semen, Ciel.”

“Ah, right…!”

She then remembered that when the Master ejaculated, there was a strong yet sweet scent that seemed to paralyze her brain.

Serena knelt beside Ciel and spoke.

“Listen well, Ciel. Fellatio means sucking on the penis with your mouth until semen comes out and causes ejaculation.”

“With the mouth? Not the vagina…?”

“Yes. You use your mouth like a vagina.”

“Aha, mouth-vagina…!”

Ciel understood quickly.

The penis was an organ that raised sensitivity through proper pressure and reciprocating movements, leading to ejaculation.

There was no condition that said one must only use the vagina to cause ejaculation.

“I’ll show you a demonstration….”

Serena fixed her eyes on Kim Doha’s penis and greeted it.

“Nice to work with you, penis. Kiss♡”

Then she immediately took the glans into her mouth.

“Mmm…♡”

What followed was Serena’s high-level skill, ‘Sucking Only the Glans,’ which she had practiced every dawn.

The glans were an especially sensitive part of the penis. Realizing this, Serena had refined a technique of stimulating only the glans with her mouth without even touching the shaft.

She stimulated the glans with the soft flesh inside her mouth and wildly rubbed the urethra with the tip of her tongue.

“Uhm, smack♡, slurp…, kiss♡, nibble♡, nibble.♡”

Then…

“Wow…!”

Ciel exclaimed in awe. The penis, victim to Serena’s skill, became fully erect in just 5 seconds, veins clearly visible.

“That’s amazing, sister…!”

“Heh heh, huff…”

Feeling pleased with her younger sister Ciel’s reaction, Serena became even more proactive.

“First, watch how I do it, and then you can follow along, Ciel.”

“Yes!”

“Mmmm…♡”

Serena immediately swallowed the penis all the way to the base.

The grand 20 cm fully erect penis going into Serena’s small mouth was an incredible sight to behold.

“Wow…”

Ciel exclaimed in awe again.

Kim Doha’s penis was naturally of a size that could not entirely fit into Serena’s mouth. Therefore, she inevitably had to use her throat to swallow it to the root.

Serena’s smooth neck was now bulging to the extent the penis had entered. To Ciel’s eyes, it looked fascinating.

“It looks tiring….”

Serena immediately began to move her head, sucking on the penis with smacking noises.

“Umph…, slurp♡, slurp♡, smack♡, smack♡, s-slip…♡”

Ciel carefully looked at Serena’s face, who was diligently sucking the penis. She was worried that her sister might be in discomfort.

However… Serena, sucking tightly, cheeks hollowed, looked truly happy.

“Sluuurp…, slurp♡, huff…, smack♡, s-slurp—♡”

After about a minute of continuous back-and-forth motion, Serena sucked strongly on the shaft one last time, pulling it out upwards.

Then, the penis, coated in Serena’s saliva and glistening, was revealed. It seemed even larger than before.

“Now, Ciel, try to do it as I showed you.”

“I’ll give it a try…!”

Ciel boldly stepped forward. First, she placed the penis near her nose and mimicked what her sister had done earlier.

“Nice to work with you, penis… Kiss♡”

Then she immediately took it into her mouth.

“Mmm…”

Suddenly, a complex array of sensations began to stimulate Ciel’s senses.

The hot temperature of the penis, the pulsating beat, the sweet scent of the leaking pre-cum, the smooth touch of the glans on her tongue…

‘Something… feels good.’

Ciel felt her heart settle. Gaining confidence, she tried to swallow the penis all the way to the base.

“Ugh…, gulp…, gah….”

The penis penetrated deep into Ciel’s mouth, poking her throat, and she let out a small cough while still holding it in her mouth.

“Ah, Ciel. Be careful when putting it into your throat so you don’t choke.”

At her sister’s advice, Ciel nodded slightly, then began to move her head up and down in a back-and-forth motion.

“Slurp…, slurp, smack….”

Every time she deeply bowed her head, the sensation of the glans poking her throat was painful. The agonizing feeling caused tears to well up, but Ciel did not stop.

“Slurp, smack, slurp, slurp….”

She did not forget to swallow the saliva and pre-cum that occasionally flowed out. Her Master’s pre-cum tasted sweet, a delicacy she didn’t want to miss.

While moving her head like this, Ciel suddenly swallowed the penis to the base and remained still for a moment.

“Smack…, slurp, s-slip, gurgle…♡”

Saliva bubbles frothed around the penis that had entered to the end of her throat. Serena looked at her sister with a worried expression.

“Ciel…?”

However… Ciel’s current state was the exact opposite of what Serena was concerned about.

She was enjoying the sensation of the penis scratching her throat.

‘This… feels so good…♡’

Her Master’s pubic hair that tickled her nose and chin, the hot penis pulsating inside her throat, and the gradually tightening lung capacity formed a sweet trio that sent Ciel’s vagina into a light shudder.

Bzzz- Buzz-♡

Ciel was unaware of her own fetishistic inclination.

‘Fellatio feels so good…♡’

She began deep-throating in earnest again.

“Umph♡, smack♡, slurp♡, s-slip♡, smack♡!”

It was even faster and more intense deep-throating than what Serena had done.

It felt good when the penis poked her throat. But to get that poking sensation, she had to move faster, deeper.

This reward system gradually accelerated Ciel’s fellatio.

“Huff…♡, smack♡, slurp♡, s-slip♡, s-slip♡, s-smack♡, s-slip.♡”

Almost losing her mind in the waves of pleasure, Ciel was craving the penis. She felt it throbbing.

Ciel knew well that this was a sign of ejaculation. She had felt it before when she held it inside her vagina.

For a moment, she was conflicted.

‘Should I swallow it right away? Or should I…?’

The Master’s semen was sweet and tasty. So, should she happily swallow it while being poked in the throat by deep-throating, or should she first receive it in her mouth and taste it before swallowing?

Ciel chose the latter. The reason was simple. Deep-throating could be done again, but semen only came out occasionally.

But was her judgment a little late?

“Ugh…, Uuugh…, Kugh……♡”

Her Master’s ejaculation started while she was pulling the penis out of her throat.

Ciel felt the semen overflowing in her mouth, running down into her nasal passages. The sticky touch of semen that stimulated her nostrils made her cry again.

“Huuuuugh…♡, Uugh…♡, Kuuuuuuugh……♡♡♡!!!”

Buzz-♡ Buzzz-♡

The bed was soaked from the large amount of love juices Ciel had released.

But Ciel’s mind had no time to worry about that, as the semen that had come up her nasal passages was now flowing out of her nose.

“Kuhack—!”

Startled, Ciel inhaled the semen through her nose but sneezed it out again. Then the viscous semen swelled, forming bubbles.

It looked as if she had blown a bubble gum bubble with her nose.

“Hehe, Ciel. Your face looks really cute right now……!”

Ciel’s face, with the penis in her mouth and her throat diligently swallowing the semen while bubbles of semen formed on her nose was adorable. Serena wanted to show this cute appearance to the Master as well.

But waking the Master right now was not possible…

Serena took Kim Doha’s cell phone and took a picture of Ciel’s appearance, even setting off the flash.

Snap-

“Uuugh……!”

Startled by the flash, Ciel inhaled, and the semen bubble shrank.

“Just wait a little, Ciel.”

Serena held Ciel’s cheeks and began to lick the semen that was flowing from her nose down to her chin.

“Huuh, Uuh, Jjueup, Heum, Ciel really, unable to behave properly……”

Serena was so pleased with this situation where she could do something for Ciel as an older sister.

“Chueup, Chuk, Huuuh… How about now? It’s clean, right?”

Ciel’s face was now neat without the spilled semen, although it was smeared with Serena’s saliva.

Feeling warmth from her sister’s care, Ciel smiled slightly with the penis in her mouth and nodded her head.

And she began to suck on it again.

“Jjueup♡, Jjuk♡, Churip♡, Jjulululup—♡”

Gulp.

Ciel, who had finished by sucking up even the semen trapped inside the penis, smiled contentedly.

“Heheheh. Fellatio is fun.”

Then Serena laughed with her.

“You did well, Ciel! A hundred points!”

“Really…?”

“Of course!”

In truth, Ciel didn’t believe Serena’s praise.

She herself thought that it wasn’t perfect since she hadn’t cleanly consumed all the semen at the end, but she played along with her sister, who wanted to compliment her.

‘My sister is really cute.’

“Heheheheh. Thanks to Serena unnie’s teachings!”

The excited girls didn’t realize it.

That they had inadvertently raised their voices instead of whispering.

“Huh?

“Um?”

Both were startled by the sudden warm touch of a hand stroking their heads.

Their Master, Kim Doha, had awakened.

“What were you two doing without me…?”

“Master…?”

“You’re awake……?”

Kim Doha raised his upper body and spoke in a voice still heavy with sleep.

“Hoo… So early in the morning…”

At those words, Serena realized her mistake.

She had started early, intending to teach Ciel, but had accidentally woken him up much earlier than usual.

She quickly lowered her head.

“I’m, I’m sorry, Master……!”

“Hmm……”

Kim Doha thought as he gently stroked Serena’s golden hair.

‘Were they trying to give me morning fellatio…?’

He felt proud but a little annoyed because he was still very sleepy.

In a low-pressure state and slightly domineering, Kim Doha spoke in a low voice.

“Serena. Present your vagina here.”

“Yes, yes!”

Serena quickly turned around and got down on all fours, raising her buttocks.

It was the beginning of a bona fide 3P.
