Taboo Manual for Raising a Succubus Girlfriend!

The girl's name was written on the slightly raised chest of her white school swimsuit - "Mian Yuyi"

"No, don't make any noise..."

The tender and lovely voice echoed in the small compartment and was soon drowned out by the sound of water.

「Click」

The sound of a door locking.

Yu Yi leaned her back against the door panel, hiding her little hand that was locking the door behind her back. Her little face flushed with a lovely light pink, and her cherry eyes swayed with watery light as she looked up at this side.

"Otherwise, we'll be discovered..."

She held her index finger up in front of her mouth and whispered a warning, her cheeks turning even redder and her succubus tail slightly curved.

"..."

Ye Si looked down at his girlfriend who suddenly broke into the cubicle, appearing a little at a loss.

"Why are you here..."

The teacher's shower room and the student's shower room are two different places, and the two sides are not allowed to enter each other.

In other words, Yu Yi has now violated the school rules.

"Because..."

Yu Yi pursed her lips and looked down at her bare feet, with her left big toe resting on her right big toe.

After hesitating for a while, she finally made up her mind, put her hands on her chest, and whispered:

"I want to help Ye Shi... do something."

The little devil's pointy ears were already burning red.

..

"Do...what?"

Ye Shi swallowed instinctively.

These words penetrated into her heart like venom.

Because the cubicle was so small, the two of them were very close, their skin almost touching, and they could even hear each other's breathing.

The atmosphere is very ambiguous.

At this moment, Yu Yi was like a little white rabbit that suddenly broke into the big bad wolf's house, so beautiful and delicious.

Her long eyelashes were covered with water droplets and trembled slightly. Her developing chest rose and fell with her breathing. Her cherry-colored succubus pupils flashed with shy watery light. Every move she made seemed to be teasing other people's nerves.

"Really..."

Ye Shi leaned forward and placed his hand on the door wall next to Yu Yi's cheek, as if to prevent her from escaping.

Water dripped down the black hair, and the blood-red pupils on the beautiful face revealed extremely strong aggressiveness.

"me..."

Yu Yi was a little frightened. She looked up at Ye Si's eyes, hunched her shoulders, and tucked her succubus tail between her legs.

She covered her pounding chest, took a deep breath, closed her eyes tightly, and nodded vigorously:

"Ah."

..

Allowed.

This small nod is like a passport to a new world, officially unlocking a new stage in "love".

Ye Shi lowered his head, admiring his girlfriend's delicate face that looked like a doll, and her soft, snow-white skin. A forbidden fire ignited in his body.

Sniff

She twitched the tip of her nose.

The scent of the succubus's skin was as sweet as a ripe peach.

Now, I can finally touch Yu Yi "legally".

Amidst the chaotic sound of water...

Ye Shi slowly lowered his body, following the most primitive desire in his body, and approached Yu Yi's small lips.

Then...

"I want to help Ye Shi, just like my future sisters do!"

Yu Yi hesitated and said the second half of the sentence.

"...?"

Ye Shi blinked as if he had been splashed with a basin of cold water.

"That is to say..." Yu Yi clenched her fists, trying to organize her words in her mind, and explained:

"Didn't Ye Shi tell me before that he had an important task for me, which was... that... we had to take a bath together."

As she spoke, her voice became smaller and smaller, like bubbles that were about to disappear.

"Yes.."

Ye Shi remembers this incident.

This was the mission in the little pink book. She had mentioned it to Yu Yi during the last magical girl gathering at the neighbor's house.

Yu Yi agreed at that time, but did not specify a specific time, so it has been delayed until now.

"I know that I am just an ordinary demon. Unlike my sister Mirai and sister Ziyin, I don't know a lot about humans and can help Ye Shi."

"But, as Yoshito's lover, I have to do something, and...there are some things that only I can do."

Recently, Ye Shi has been hanging out with other girls, and every day when he comes home, he smells like many girls, which makes Yu Yi feel uneasy.

Although she knew that this was all part of her job, she couldn't help but think in strange ways. Plus, gossip and rumors about Ye Si were always circulating among students, which made Yu Yi even more restless.

After the swimming lesson just now, she saw with her own eyes how Ye Shi interacted intimately with other girls, and her patience reached its limit.

"Isn't it okay to do this?"

Yu Yi raised her head, her cherry eyes looked like she was about to cry, swaying shyly in the dim compartment.

"of course can."

Ye Shi responded firmly.

I believe no one would refuse to be in the shower stall with a lovely girlfriend.

but...

Ye Shi pricked up his wolf ears, and after confirming that no one else was in the teacher's shower room, he lowered his body and asked:

"Isn't it stipulated that in school, our relationship is that of teacher and student?"

Ye Shi remembered it very clearly. This was the rule proposed by Yu Yi, and he had been scolded several times for crossing the line.

Yuyi could have suggested taking a bath together after returning home, but she chose this time.

Isn't this breaking the rules I set?

"Woo..."

This question directly hit Yuyi's pain point.

She was so shy that she felt like smoke was coming out of her head. She held her blushing little face in her hands, not knowing how to answer.

"I saw Yoshito getting physical with another girl, so I got jealous and rushed in on a whim." Or something like that...

I can't say it no matter what!

"Then, I'll go back..."

Yuyi turned around, put her little hand on the door lock, took the initiative, and pouted as if she was about to leave, threateningly.

"Don't leave."

Ye Shi immediately reached out and grasped the back of her hand with lightning speed, while his other hand hugged her slender belly from behind.

"Stay here."

She bent down to match Yu Yi's height and spoke to the pointed little ears.

As expected of a succubus.

"Now, you asked me to stay."

Yu Yi showed a naughty smile, and seemed to have gradually been able to understand Ye Si's heart. The succubus tail swayed gently.

However, facing such a strong reaction from my lover, I still felt very complicated inside, a little scared, and a little secretly happy.

"So.."

Amid the sound of dripping water, Yu Yi slowly turned around, looked up and saw through this side, her cherry-colored pupils faintly showing the heart shape unique to succubus.

She tried to stand on tiptoe, half covering her mouth, and whispered in a sweet voice that could melt reason:

"Now, we are complicit."

Light eyelashes flutter gently.

The succubus swung its tail, and in her faint smile, her pointed little devil fangs were faintly revealed. She called out coquettishly:

"Yoshito-sensei~?"

..

Succubus...it's indeed a race that can bring depravity to people.

..

..

The water flow forms a small vortex at the drain outlet.

"Rustle, rustle"

The sound of smooth cloth rubbing against each other.

In the narrow compartment, Ye Shi once again hooked the shoulder straps of her swimsuit, preparing to take it off.

"W-what are you going to do?!"

Yu Yi suddenly panicked at this moment and quickly covered her eyes:

"Why are you taking off your clothes all of a sudden, stupid dog!"

The cherry-colored eyes looked straight over here through the gaps between the fingers.

"Aren't you taking a shower...?"

Ye Shi tilted her head, her jet-black hair falling on her bare shoulders, her red eyes filled with confusion.

"Put it back on quickly, don't take it off!"

“How can I wash it without taking it off…”

"You can take a bath in your swimsuit!"

"Well.."

indeed.

Ye Si drooped his animal ears, his red eyes showing frustration, and he felt a little listless.

The "bath" that Yu Yi mentioned was a little different from what she imagined.

"Really, you big pervert..."

Yu Yi understood the expression on Ye Shi's face, and her little face flushed slightly. After a brief thought, she squeezed her soft thighs together and murmured:

"If you want to see it, it's not..."

"Ok?"

"W-Nothing, stop staring at me, you pervert, don't think you're amazing just because you have long legs!"
