Inside the room, Shuang Yuzhu reached her third orgasm, but she and Ling Yun were still unsatisfied with their sexual activity. He sat on a small chair with his wife on his lap. He gave her a deep, passionate kiss, with his cock continuing to pound her butthole.

Outside the room, Shuang Meixue’s body jerked a few times. She closed her mouth tightly to hold back her moans, a taste of pleasure coursing through her body, and her legs rubbing against each other. She pulled her hand up and stared blankly at her fingers. For the first time in her life, she experienced what people call an orgasm, and she was orgasm from spying on her sister having sex with her husband.

Shuang Meixue enjoyed and felt addicted to the aftereffect of her orgasm, making her crave more. She imagined herself in her sister’s position and Ling Yun’s cock pounding her two holes like what he did with Shuang Yuzhu.

Shuang Meixue sighed in her heart and returned to her room, but she did not rest. She removed her messy dress, lay on the bed, and satisfied herself. She inserted her fingers into her delicate, virgin pussy, imagining it as Ling Yun’s cock. "Mhmm... brother-in-law... please fuck me like you fuck my sister..."

Shuang Meixue masturbated until she reached another powerful orgasm, and she fell asleep afterwards.

Meanwhile, Shuang Yuzhu was already curled up in Ling Yun’s arms and letting out soft snores. Her expression showed satisfaction after finishing their sexual activities, and she fell asleep in her husband’s arms, feeling secure.

On the other hand, Ling Yun glanced at the slightly open window several times. Although Shuang Meixue suppressed her aura and used an artifact to hide her presence, he knew that she was spying on his sexual activity with Shuang Yuzhu earlier.

Ling Yun inwardly sighed, closed his eyes, and accompanied Shuang Yuzhu to sleep.

In the morning, Ling Yun, Shuang Yuzhu, Cui Xiaoyan, and Shuang Zong had gathered in the dining hall for breakfast. However, Shuang Meixue still hadn’t shown up, and her sister decided to go check on her.

When Shuang Yuzhu entered her sister’s room, she found Shuang Meixue still sleeping soundly naked. Her nose twitched when she smelled a familiar scent from her sister’s room, and she approached her to check on her, but she found traces of an orgasm on her bed.

’Did my sister really masturbate last night? Why did she do that? She’s not the kind of woman who would do that kind of thing.’ Shuang Yuzhu thought of something that made her gasp in shock. She realized that only she and her sister lived in that area, and she realized that her moans were very loud when she had sex with Ling Yun. ’Could it be that she was peeking at us last night? Did she masturbate by imagining my husband last night?’

After the shock was over, Shuang Yuzhu’s lips curled into a beautiful, seductive smile. She sat beside Shuang Meixue, who was still sound asleep, and stared at her sister’s face.

Shuang Yuzhu took out a bottle of Ling Yun’s yang qi from her storage ring and poured it into her mouth. She looked at Shuang Meixue, carefully opened her lips with her slender fingers, kissed her, and poured the yang qi into her mouth.

Feeling her sister’s kiss, Shuang Meixue opened her sleepy eyes. She didn’t understand why her sister was kissing her, and she was confused by the liquid she poured into her mouth, but she swallowed it immediately. ’What kind of liquid is this? Why is it so thick but tasteless?’

After finishing, Shuang Yuzhu separated their lips and looked at her sister with a mischievous smile, making Shuang Meixue awkward with feelings of guilt. "Tell me, sister. Did you masturbate while imagining my husband last night?"

"I didn’t—"

"Don’t lie to me." Shuang Yuzhu pointed to the bedsheet beneath Shuang Meixue’s lower body. "If you didn’t do that, why are you sleeping naked? Why can I smell your yin qi? I know that you’re not that kind of woman, and you wouldn’t do such a thing without reason."

Shuang Meixue turned her embarrassed face to the side as she didn’t know what to say to answer her sister.

"Did you peek at me having sex with my husband last night?" Shuang Meixue didn’t want to answer her sister, but Shuang Yuzhu already knew the answer from her blush, which had reached the tips of her ears. "Did you like what you saw last night? My husband’s cock was so long and thick, and I got complete satisfaction when it pounded my pussy and butthole."

Shuang Meixue couldn’t stand it anymore and sat directly on the bed. "Sister! My brother-in-law has already ruined your innocence! I... I like my innocent and childish sister! You... you acted like a little bitch last night!"

"Hehe," Shuang Yuzhu giggled, rubbing her sister’s cheek. "Sister, I’m no longer a child and I’m a wife now, remember? Ling Yun is my husband, so it’s natural for me to act like that to please him. Besides, he has dozens of wives by his side, and some of them are much better than me, like Sister Ming. If I don’t change myself a little, I’m afraid I’ll lose out to them, and my husband will push me aside."

Shuang Meixue looked at her sister in a daze, recalling all of Ling Yun’s women. "What-"

"Let’s talk about that later, okay? Our parents are waiting for us in the dining room, so we should join them now." Shuang Yuzhu waved her hand and cleaned her sister’s body with her qi. "Hurry up and get dressed."

.

.

.

The two women arrived at the dining room, and Shuang Meixue put on her usual look so as not to arouse her parents’ suspicion. However, her heart pounded when she saw Ling Yun, and her ears flushed slightly, remembering his sexual activity with her sister last night.

Shuang Yuzhu sat beside Ling Yun and talked to him through the harem connection that no one could eavesdrop on. ’What if I invite my sister to watch us have sex tonight?’

’No,’ Ling Yun refused. ’Let your sister think about what she wants first, and you don’t have to force her to go to my side.’

’Alright then.’ Shuang Yuzhu knew that she was not forcing Ling Yun, but she did not want to give up, and she devised another plan to bring her sister to his side.

After they finished breakfast, Cui Xiaoyan and Shuang Zong left to take care of the Shuang Clan’s business. Shuang Meixue returned to her room to cleaned herself, but Shuang Yuzhu hurriedly followed her.

Meanwhile, Ling Yun left the Shuang Clan and headed to other floating islands. There were several floating islands in the Boundless Heaven Domain, but he had only been to three of them.

"Why are you following me, Sister?"

"Hehe," Shuang Yuzhu took off her dress, confusing Shuang Meixue. She didn’t bother explaining and quickly took off her sister’s dress. "I haven’t been home in a long time, and we haven’t soaked together in a long time, so we’ll do that. After everything you saw last night, you definitely want to know more about my husband, right?"

"I—" Shuang Meixue nodded embarrassedly.

"Let’s go." Shuang Yuzhu pulled her sister to the bathing area, and the two soaked in the small pool side by side. "Sister, you inherited our mother’s genetics; your body is much more mature and sexier than mine."

Shuang Meixue raised an eyebrow as her sister stared at her breasts jealously. She held her breasts from both sides and perked them up. "You’re jealous of me, but my breasts always make me insecure. Wherever I go, all the men stare at them, and they can’t wait to pounce on me."

"Isn’t that normal? All men are always like that, and most of them like women with big breasts like you." Shuang Meixue did not argue with Shuang Yuzhu, but she was uncomfortable feeling those men’s gazes on her breasts. "Did my husband stare at your breasts when you met him yesterday?"

Shuang Meixue recalled her first meeting with Ling Yun yesterday before shaking her head. "My brother-in-law didn’t look at me that way, and he looked at me like any other woman without any lust. After all, he has so many wives who are much sexier than me, right? What woman in this universe can compare to the Lust Spirit and the Life Goddess? They are both the most beautiful and sexiest women I have ever seen, and I feel jealous of them."

"Yes," Shuang Yuzhu agreed. "The first time I saw Sister Xi and Sister Ming, I felt jealous of them too. I wished I had half their beauty and sexiness, but I knew that was impossible."

"Does my brother-in-law want you to be like them, Sister?"

"No." Shuang Yushu leaned against the side of the pool. "My husband asked me to be myself, and he told me that he liked me for who I am. After I met all his wives, I realized that I was better than some of them, so I found the confidence to be his wife."

Shuang Meixue nodded in agreement because her sister had already shown her all of Ling Yun’s wives. Some of them, like Yi Mingzhu, pale in comparison to her sister.

"Sister, I spoke with my husband last night, and I want to take you to live with us at our residence."

"Eh?" Shuang Meixue was surprised by that, and her mind wandered to something that made her blush. "Why... why do you want me to stay with you guys?"

"Hehe," Shuang Yuzhu said as she created a qi screen that displayed the Yunlong Zhuzhai. "You may not know this, but the time flow in our residence is ten times faster than the outside world, so you can cultivate much faster than other cultivators."
