〈SYSTEM〉 You have acquired the title ‘Experiment Subject of Zaln Island.’

Physical strength is decreasing.

Muscular strength is decreasing.

Morality is decreasing.

Rosé, who obtained the new title, returned to her private room and opened the ‘Status Change Record’ on her desk. It was a notebook that Dain had given her to note down her symptoms every hour.

「Kithlode Standard Time: 19:44

Slight redness where applied. Slightly tingling to the touch.」

There weren’t many noticeable changes within the hour. If anything had changed, it was the ability points.

〈SYSTEM〉 Ability values fluctuate due to occupational activities.

Physical strength decreased by 3.

Muscular strength decreased by 3.

Morality decreased by 4.

The ability values had already started to decline. Rosé felt slightly anxious, but she could still endure it for now. It’s alright. Once her role as an experiment subject is over, she will receive communication fees.

With a sigh, she swiped the system screen with her hand and flopped onto the bed.

Could it be because of seasickness from coming to the island? Exhaustion overwhelmed her whole body, even reaching her eyelids.

Since she was already lying on the bed, she thought she would take a brief nap and then wake up. With that in mind, she buried her face in the pillow.

•·················•·················•

She woke up just after midnight. Rosé wiped her sweaty neck. She couldn’t distinguish whether it was a dream or reality.

Strangely, sweat accumulated all over her body, and her feet felt cold. Her chest was congested, as if something was pressing on it.

When she pulled back the blanket, she noticed that her blouse was a mess, all crumpled. The second and third buttons from the top had popped off.

Her chest had really grown. The blouse, tailored to fit perfectly around her chest, was now torn to such an extent. She couldn’t believe it, so she gently squeezed her chest, feeling a tingling pain.

Even her n*pples were swollen. What used to be flat had swollen up round and firm. Could this be the side effect?

Rosé enthusiastically toyed with her enlarged br*asts using her small hands. As she wondered if her sensation was dulling, her n*pples twitched briefly again.

“Ah, ah, huh…!”

Cold sweat dripped down. It was similar to the tingling sensation she felt in her chest a little before menstruation. The problem was that it was even more severe than that.

Even though she gently touched and squeezed her n*pples with saliva on her fingers, there was no response. After enduring for another 30 minutes, Rosé’s body trembled as if she would pass out.

Her n*pples felt itchy to the point of madness. What used to be soft and supple had become firm now.

“Ah, haaahh.”

Trembling, Rosé unbuttoned her blouse with her shaky hands. Then, she stepped outside with wobbly legs.

She needed Dain’s help. The lab door was open, so there was no need to knock.

Dain, who sensed her presence, checked the visitor. Having been researching until dawn, he Emmetted a faint smell of chemicals.

“Miss Mora?”

Rosé felt relieved by his calm voice and burst into tears, which she had been holding back.

“Hindley, my n*pples… They’re strange. Please… help me.”

“Oh no!”

Dain led her, sobbing, to the patient chair. He then offered her a warm herbal tea for comfort. With his thoughtful care, Rosé felt relieved and cried even harder.

“Miss Mora, is it possible for me to see it?”

Dain’s composed voice became a source of solace. Slightly tilting her head, Rosé slowly took off her blouse.

Soon, Dain’s eyes were greeted by br*asts much larger than before, beyond comparison.

“It’s astonishing.”

A genuine exclamation escaped from Dain’s lips as a scholar. Although he had no interest in women, he knew well how an average woman’s br*asts looked through textbooks.

But this pair of br*asts was truly…

“I don’t know how it may sound, but what Miss Mora needs right now is someone who can suck your br*asts. If the side effects are this strong, you can’t solve it alone.”

Despite his efforts to stay calm, Dain’s voice was rough, unlike during the evening. He was witnessing the most perfect br*asts he had ever seen in his life.

The elongated n*pples, small and dusky ar*olas, full and bouncy br*asts, smooth and fair skin—it was all there.

Although the size was slightly above average, they were already beautiful in themselves. If there was a golden ratio for br*asts, this woman’s br*asts would become the standard of an empire.

Dain anxiously waited for Rosé’s response. And the voice that finally came was enough to captivate him.

“Okay, I got it. Hmm. Please make sure it doesn’t hurt too much somehow.”

Dain’s feet instinctively moved forward. For someone who had stayed up for three nights, he was breathing heavily and his face was also haggard.

Rosé continued to moan in agony. It was a clumsy movement to suck her br*asts.

Dain had no choice but to press down on her trembling thighs with his hand. Rosé didn’t complain either.

“From now on, I will suck Ms. Mora’s n*pples. It will hurt at first, but you have to endure it.”

“Yes, I’ll endure it. Please, Mr. Hendley…”

Dain impulsively squeezed her br*asts tightly. When she moaned, his legs trembled.

Suddenly, he felt the urge to gag her. There was a leather gag prepared for an experiment subject that couldn’t be anesthetized.

But it was impossible to do such a thing to such a fragile test subject. Suppressing his greed, he gently sucked on her er*ect n*pples.

The n*pple that entered his mouth was pitiful and cute. He flicked the part of the head that was particularly red with the tip of his tongue.

“Hmm, hmm…”

This time, he licked up from the base and pressed down hard at the end. It hurt quite a bit, so she resisted. This must not be good.

Groaning, he pressed the br*ast with his hand and pulled out the n*pple longer. It slipped into his mouth along with the flesh of the ar*ola.

Dain licked the n*pple pole with his tongue. He could taste the unique savory taste of flesh.

“He, Mr. Hendley. This is… strange!”

“Just endure it. It’s okay.”

Dain spoke roughly as if he were annoyed and swallowed the br*ast in a hurry. On the other hand, he twisted the n*pple with his hand while shaking it. One with his mouth, one with his hand. How efficient is this method?

Meanwhile, Rosé felt like dying. The sucking force was so strong that her n*pples were about to break. Moreover, every time he twisted her n*pples round and round with her hands, she cried.

But it wasn’t just pain. At some point, Rosé’s hips began to move. Every time Dain squeezed and spread his hands, a slippery l*quid flowed out.

“Uh, aah… I want to stop, Mr. Hendey.”

As her lower abdomen tightened, she felt a pleasant sensation. Rosé was in a state of fear as this sensation was new to her.

Dain was no different. He was a man who had attended regular s*x education classes and had m*sturbated out of curiosity a few times. Even he was perplexed by his er*ect p*nis.

“The other side is still left. Moreover, this area is quite swollen.”

Dain changed position and grabbed the right br*ast. The n*pple was plumper on the side where her heart was.

He licked the n*pple with his tongue and sucked on it. There was a sweet smell here too.

To enjoy it a little more, he flicked the n*pple pole with his tongue. The saliva-soaked tip stretched out like a small bud. It was so cute that he laughed.

“You seem to be urging me to keep sucking.”

He sucked the n*pple hard, his lips tightly wrapped around it. The sucked n*pple became taut. His face looked like that of a beast under the influence of drugs.

“N*pple, hah, it hurts! Ahh!”

When he thought of letting go, he licked it softly again before sucking it hard once more. As a result, the ar*ola became red and swollen, not just the n*pple.

Ah! My n*pple!

Rosé looked at Dain, who was sucking her br*ast like a madman, and finally burst into tears. Regardless of whether she cried or not, Dain continued to relentlessly torment her n*pple.

“Do you like me to suck them hard like this, or haa. Gently?”

His low and rough voice sounded like he might do something violent. Rosé’s tearful lips trembled as she didn’t know how to respond. Then Dain bit her n*pple with his fang without warning.

“Ah! It hurts…!”

“As a test subject, please answer properly if a researcher asks you.”

What an evil researcher! Sucking my n*pples until I collapse!

Internally, Rosé resisted fiercely, but in reality, she could not resist Dain.

As the n*pple, which had been rolling around in his warm mouth, came out into the cold air, she couldn’t stand the unbearable pain. It felt like only that part was crushed by ice.

To make matters worse, she shivered as if she would catch a cold and had no choice but to plead with Dain.

“My, my chest is cold. Mr H-Hendley, please suck on it like before.”

As Rosé came out of her submissive position, Dain chuckled. Although he wanted to bring her some ice to roll on her n*pples, she was still a test subject officially. For now, that is.

“Pull yourself together, Ms Mora. Don’t tremble like that, be pretty.”

“Uh, huh….”

Despite knowing that it hurt to bring her br*asts together in the middle, Dain cruelly ordered her to do so. The side effects still hadn’t subsided.

Rosé had no choice but to lift her chest up as much as Dain wanted. The br*asts rose up straight. The n*pple, which had been soaked in saliva, trembled in the cold.

“Now tell me your condition.”

“Mr Hendley, what is….”

“Because I have to record Ms Mora’s physical changes.”

Dain picked up a notebook and pencil from the desk. With his focus blurred, he seemed to be more interested in something other than research purposes.

“Hurry up.”

Dain didn’t seem to have any intention of stepping back. He had brought her br*asts together to suck them, but now he had to report on the status of her n*pples.

Still, there was no other way. If he wouldn’t suck on them now, she felt like she would die.

“The tip of the n*pple… It’s c-cold and itchy. When Mr Hendley sucked it before, it was warm, but now it’s… Huh, it’s too cold and it hurts… The br*ast feels heavy and lumpy like a bruise… But when Mr Hendley touched it, it was definitely…”

“What was it like, Ms Mora?”

Rosé’s lips protruded as if she would burst into tears at any moment. It was a shameful question that made her face flush.

But why was she getting excited? Without realizing it, she spoke shamefully.

“When Mr Hendley squeezed my chest before, my flesh became soft and squishy… When the pressure was released, it felt… good. When it’s tightly pressed, my head turns white.”

Dain pretended to write down Rosé’s words with his pencil. But what Rosé saw in her eyes was the bulging front of his pants.

Something like a swollen cucumber was coming down through his left gr*in. No, on closer inspection, it wasn’t just something ‘like’ a cucumber, but really a cucumber-like object jutting out.

Rosé wanted to ask about its nature. If she could.

“Now that the recording is over, I’ll suck it again.”

“Uh, wait a minute…”

“Until all the swelling is gone, I’ll take it slow.”

She moved her hips back, but all she could feel was the backrest. With her eyes closed, Rosé was approached by Dain’s huge cucumber.

Unfortunately, nothing more than n*pple sucking happened that night.

But rumors have it that the delicate moans of the woman and the sound of br*asts being sucked were causing noise between the floors, spreading from room 2 to downstairs.

•·················•·················•

The morning of the third day of the experiment had dawned. Rosé’s face was half swollen from suffering two nights of chest chills.

Dain approached Rosé with a bottle of extract from a giant rose. She had w*t her blouse in a half-given-up state.

“I sucked it all night, but it’s still swollen. But it suits your big chest.”

Dain stood up straight and tapped the er*ect n*pple. They were plump and tasted like something you could chew on.

If he applied the medicine today, it might even get bigger. Then he planned to tie the n*pples together with string to measure the circumference.

“I’ll apply it now.”

For today, Dain had found the thinnest gloves. The smooth gloves touched the n*pple. The medicine slowly spread on the flesh and was applied.

“Ah…oh…”

The strange sensation of the gloves gave more pleasure than bare skin. Soon, high-viscosity fl*id seeped into the n*pple flesh. Softly, very slowly.

“Ah, haa…”

“Don’t forget to report your condition every hour, Ms Mora.”

Dain said as he opened Rosé’s shirt. The shirt was his. Rosé’s blouses didn’t fit anymore due to her growing n*pples.

Rosé got off the chair with trembling legs. At that moment, Dain didn’t miss her swaying chest.

“If you’re tired, come back again.”

A subtle voice lingered in Rosé’s ears.
