Dual Cultivation

"S-Su Yang… Are you sure that's safe?" Qiuyue asked him in a nervous voice as Su Yang's tongue licked every nook and cranny of her cave— or as far as his tongue could reach.

"Yes. As long as I don't penetrate you, it'll be fine." Su Yang said to her with her Yin Qi all over his mouth, looking like a child after eating a meal in a sloppy manner.

After reassuring Qiuyue that using his tongue was safe, Su Yang continued to lick her pink slit for many minutes.

"Aaaah~!"

Qiuyue moaned in a blissful voice as her little sister drooled with Yin Qi.

And although Su Yang cannot absorb her Yin Qi due to having an insufficient cultivation base, that did not mean he could not consume them normally. Therefore, Su Yang licked every drop of Qiuyue's Yin Qi as though they were a priceless treasure that cannot be wasted.

"Mmm!"

"Aaaahn~!"

Su Yang drilled Qiuyue's tight cave with his tongue while imagining what it might feel like if he were to replace his tongue with his divine rod, but alas, that's an experience for another day.

After kissing and licking Qiuyue's slit for almost an hour straight, Su Yang stood up and removed his clothes, revealing the raging dragon that had been hiding underneath this entire time.

"..."

Qiuyue stared at Su Yang's divine rod with a dazed look on her peerless face, mostly because she was lightheaded from Su Yang feasting on her lower body like a hungry beast that hasn't eaten in weeks.

"Do you also want to taste it?" Su Yang asked her with an enchanting smile on his face that was further enhanced by the moonlight coming from the window.

After staring in silence for a moment, Qiuyue nodded her head.

Su Yang then laid on the bed with his hands behind his head.

"Go ahead and feast to your heart's content," he said to her afterward.

Qiuyue swallowed nervously, and she looked at his domineering sword with a hesitant expression on her face.

Seeing this, Su Yang smiled slightly before looking at the ceiling and closing his eyes.

When Qiuyue noticed that Su Yang had closed his eyes, she felt somewhat relieved, and after struggling with herself for half a minute, Qiuyue eventually grabbed Su Yang's throbbing hot rod with her fair hands that had a somewhat cool feeling to it.

'This is not my first time touching his… I shouldn't be so nervous!' Qiuyue strengthened her resolve.

After playing with Su Yang's rod for a few seconds, Qiuyue opened her mouth and swallowed the tip of Su Yang's meatstick before licking every nook and cranny with her tongue.

"Aaah…" A few seconds later, Qiuyue stopped sucking for a brief moment to release a satisfied noise before taking a deep breath and continuing, keeping her mouth around his rod for much longer this time.

'What a delicious taste… It's like I am sucking sweet dew from a straw but in small amounts…' Qiuyue thought to herself as she gently sucked Su Yang's fresh Yang Qi.

After sucking on Su Yang's rod for nearly an hour as well, Qiuyue finally stopped, panting heavily afterward.

Su Yang opened his eyes as well, and he looked at her and asked, "Are you ready?"

Qiuyue quickly nodded.

"Since it's your first time, let me loosen your back entrance first. Show me your back." Su Yang said to her.

Qiuyue followed his instructions and kneeled on the bed with her round buttocks sticking towards Su Yang's direction.

The moonlight from the window shined on Qiuyue's smooth buttocks, making it seem like there were suddenly two beautiful moons before Su Yang.

"I'm going to use some Euphoric Oil to make it easier for you to endure."

Su Yang then retrieved a bottle of Euphoric Oil and dipped his fingers into it.

"It will be a bit cold at first." Su Yang warned Qiuyue mere seconds before he tapped her butthole with his soaked finger.

"Ahhh!"

Qiuyue subconsciously clenched her butt at this cold sensation.

"Relax…" Su Yang said as he rubbed the outside of her hole with his finger.

"I'm going inside now."

After another warning, Su Yang slowly pushed his index finger inside her tight butthole, feeling a strong squeezing sensation.

"Are you okay?" Su Yang asked her as he continued to slowly push his finger deeper inside her butthole.

"I-It feels a bit weird, but I am okay…" Qiuyue mumbled.

"Good. Continue relaxing your body."

While one of his hands focused on loosening her butthole, Su Yang used his other hand to tease the dripping wet front entrance.

"Mmmm~"

Qiuyue pressed her face against the pillow and moaned.

A few seconds later, once his entire index finger was inside her butthole, Su Yang pulled it out without actually leaving her hole, and he began thrusting his finger into her tight hole.

Qiuyue's body trembled nonstop whilst her front entrance drooled with transparent Yin Qi.

"How do you feel?" Su Yang asked her a moment later.

"G-Good…" Qiuyue responded with a muffled voice, feeling her body temperature and lust rising due to the Euphoric Oil.

Once Qiuyue became comfortable with one finger inside her butthole, Su Yang increased it to two fingers, even stretching her butthole open with his fingers.

"Aaaah~!" Qiuyue moaned loudly.

Many minutes later, Su Yang pulled his fingers from her butt and said, "It should be ready for the real thing now."

Hearing his words, Qiuyue swallowed nervously.

Su Yang then poured some of the Euphoric Oil on his dragon until it was all coated in the liquid.

"I'm going to start with the tip. Are you ready?"

After a brief moment of silence, Qiuyue nodded her head without making a sound.

Su Yang did not immediately begin. Instead, he took a deep breath to calm himself down.

Even though he didn't look like it from the outside, Su Yang was actually quite nervous, as he wasn't certain whether this is really safe for Qiuyue or not. After all, if the rumors were false and the curse activates, there is a high chance of Qiuyue not being able to resist the curse and dying, and he will never forgive himself if that were to happen.
