Su Yang silently stared at Qiuyue's smooth and round buttocks and her small butthole that was slightly moving in and out, almost like it was alive and breathing.

If it was any other woman before him right now, he would not hesitate to plunge his sword deep into that dark hole and begin ravaging it. However, since this is Qiuyue, who has the same bloodline as Yuehai, it made Su Yang hesitate, as what happened to Yuehai when the curse activated still lingers in his mind to this day.

The pain on Yuehai's face, Su Yang would never forget such an expression for the rest of his life.

After a minute of pure silence and stillness, Qiuyue's voice suddenly resounded, "It… It's okay, Su Yang. I trust Sister Tangxi. Stick it inside me…"

Su Yang swallowed nervously after hearing Qiuyue's words. Is this really okay? He hasn't doubted himself this much for a very long time— it was a nostalgic feeling that brought him back to the days when he was still an inexperienced little brat who doubted everything.

A few more moments later, Qiuyue lifted her head from the pillow and turned around to look at him with a fully flushed face, and she said, "Su Yang… We're already at this point… And you are responsible for it. Therefore… Take responsibility and stick it in my butt!"

Su Yang snapped out of his daze after hearing Qiuyue's bold words, and he nodded.

"Okay. I'm putting it inside, Qiuyue."

After taking a deep breath, Su Yang moved his hips slightly forward and poked Qiuyue's throbbing butthole with his thick rod.

"Oh!"

Qiuyue subconsciously moved her butt away when she felt something hard and wide threatening her small hole.

However, two large hands suddenly grabbed her buttocks a second later, and Su Yang pulled her butt until his rod was poking at her back entrance again.

"Don't run away now, Qiuyue." Su Yang said as he pushed the tip of his rod into Qiuyue's butthole, immediately spreading it widely.

"Ahhh~!"

Qiuyue could feel an indescribable feeling coming from her rear, causing her to moan out loud.

However, since Su Yang's meatstick as well as Qiuyue's butthole was soaked in Euphoric Oil, it wasn't actually that painful, and Su Yang managed to stick his rod into her rear entrance almost instantly.

Of course, it was still tight as hell back there, and Su Yang could feel Qiuyue's warm insides squeezing his rod, almost as though it was threatening to crush it.

Furthermore, as though the hole was alive, Su Yang could feel a sucking sensation inside her dark cave that slowly pulled his rod deeper inside before pushing it back outside a little.

"I'm going deeper now," Su Yang warned her before he proceeded to shove his thick rod deeper into her back entrance, stretching her skin and hole even more.

Qiuyue gritted her teeth as she endured this unfamiliar and almost shocking experience.

A few moments later, Su Yang's entire shaft from the tip to the end was inside Qiuyue's butthole.

"How do you feel?" Su Yang asked her afterward.

"Do I really have to answer that?" Qiuyue said with her head burrowed inside the pillow again.

"I'm going to move now."

After giving Qiuyue sufficient time to prepare herself, Su Yang began moving his hips, shoving his thick meat stick in and out of her tight hole.

"Ahhh~ Ahhh~!"

Qiuyue quickly began moaning, and her front entrance drooled with Yin Qi like never before, forming a small and sticky puddle on the bed.

After pounding Qiuyue's butthole for many minutes, he suddenly said to her, "Qiuyue, turn around. I want to see your beautiful face."

"..."

Qiuyue did not respond to his words, mostly because she was too embarrassed to turn around.

After a moment of silence, Qiuyue began moving her body, albeit a bit stiff like a wooden puppet.

A few seconds later, Qiuyue turned her body around and laid on the bed normally, and she did all of this while Su Yang's rod was still inside her butt.

Su Yang ignored the perfect view of her body and went to kiss her.

"Mmm…"

Qiuyue quickly indulged herself in the passionate kissing, and Su Yang began moving again as they continued to kiss each other.

They stopped kissing many minutes later, and Su Yang focused on thrusting his rod into her body whilst his gaze stared at Qiuyue's beautiful face and body intensively.

"Spread your legs and let me see it." Su Yang said to her.

Qiuyue nodded in a bashful manner and loosened her legs, showing him her wet slit.

Su Yang licked his fingers before rubbing her slit.

"Mmmm~!"

Qiuyue's body trembled with delight in response to his teasing.

"Do you like this?" Su Yang teased her little sister some more, even gently pinching her pink pearl.

"Ah~!"

An abundant amount of Yin Qi gushed from Qiuyue's cave almost immediately after Su Yang pinched her weak spot.

The two of them continued to cultivate in this manner for a few more hours until Su Yang finally released his Yang Qi inside Qiuyue's butthole.

"Aaaaah~!"

Qiuyue could feel hot liquid gushing up her butt until Su Yang unplugged his rod from her hole, allowing the Yang Qi to flow out like a waterfall.

And just as Qiuyue expected a break, Su Yang plugged his rod back inside her butthole before speaking with a smile on his face, "I'm going to fill you up all night, Qiuyue— No, we're going to do this for the next few days until we're both satisfied!"

"Are you sure? What about your appointments with the disciples and the others?" Qiuyue asked him.

Su Yang chuckled and said, "They can wait. I'll make it up to them later, but right now, for the next few days, I will be yours entirely, and you will be mine."

Hearing his words, Qiuyue couldn't help but show a bright and blissful smile on her face, and she nodded.

"Okay…"

And the two of them continued their cultivation session shortly later, remaining inside that room for almost an entire week, only taking breaks to change the bedsheets since they were soaked in Yin Qi and Yang Qi.
