Yao Xin wasn't one to be taken advantage of. Standing at the door, she laughed and said, "Come on, who cares about seeing Xu Bin's skinny body? You're acting like you're the one losing out. Hurry up and come down."
"Wait a moment!"
"What for?"
"My husband hasn't finished yet, you go ahead."
This statement shocked not only Yao Xin but also Yao Le'er, who couldn't believe it came from their usually shy second sister. Even Xu Bin was taken aback.
Looking at Yao Nan, he saw her affection meter at 95%. He wasn't sure when it had risen so high, but perhaps it was the result of all the little things he had done for her, adding up over time.
Yao Nan then leaned down to take her husband in her mouth again, her eyes glazed over with desire as she moved her head up and down, making wet, slurping noises. Her hands gently caressed his testicles.
Xu Bin stroked her head, looking into her face, which reminded him of Airi Suzuki, and said softly, "Baby, go see what Mom wants. I'll be fine."
"But won't you be uncomfortable?" Yao Nan asked, pulling back and stroking him with her hand.
"I'll be okay," Xu Bin assured her, smiling gently. "You know I can last a long time. If you want to make me finish with your mouth, you'll need more practice."
"Then I'll go downstairs," Yao Nan said, blushing deeply as she put on her sleep dress. "We can't do this for the baby's sake, but I promise I'll take care of you properly later."
With that, Xu Bin locked the door behind her and used an old phone to connect to an app, immediately picking up the sounds of his mother-in-law, Shen Ruyu, speaking.
"Where's your second sister?"
"I don't know, maybe she's still with her husband," Shen Ruyu replied.
"Oh, that girl, she knows better than to do this at her stage, and Xu Bin should know better too. They're asking for trouble," Shen Ruyu scoffed.
"Mom, don't worry, they're just fooling around. I saw her underwear; it's still on," Yao Xin assured her.
"What? You saw?"
"Yeah, I walked in on them. Old habits die hard; I used to do the same when it was my room," Yao Xin explained.
"You're something else. What if you scared them?"
"Nah, it's fine. I just took a quick look," Yao Xin said nonchalantly.
Just then, Yao Nan entered the room. "Mom, you wanted to see me?"
Shen Ruyu pulled her daughter aside, "Nan, your sister said you were... taking care of your husband."
"Yes, Mom," Yao Nan admitted shyly.
Yao Xin, meanwhile, couldn't resist teasing, "Nan, you've got a talented little mouth there. You said you'd finish him off quickly, huh? Didn't swallow too much, did you?"
Xu Bin listened, his excitement building. People were naturally curious and a bit voyeuristic.
Yao Nan blushed and replied, "He hasn't finished yet. That's why I came down. I thought you needed me for something important, Mom."
The three women started chatting more naturally, their conversation flowing freely now that there were no men present.
"You silly girl," Shen Ruyu said, exasperated. "Your sister said you should let him finish before coming down. You're being foolish."
"Mom, why did you have big sister call me? What's so urgent?" Yao Nan asked.
"You're pregnant and can't have sex, so you need to find other ways to satisfy your husband," Shen Ruyu explained.
"I just said, how could it be so quick," Yao Nan said, puzzled.
Xu Bin smiled to himself, pleased that his mother-in-law seemed impressed with his stamina.
Yao Xin, ever the curious one, asked, "Mom, how do you know so much about their... activities?"
Shen Ruyu didn't bat an eye. "Their old room had terrible soundproofing. I could hear everything from the living room. They'd go at it for twenty to thirty minutes every time."
"Really? I thought it would be quicker," Yao Xin said, surprised.
"Trust me, I know," Shen Ruyu said with a knowing smile. "And Nan, try to keep it down when your sister is home. She can probably hear everything."
"Wow, so my brother-in-law is quite the stud," Yao Xin teased. "I thought he was a quick shot."
"What does Nan sound like when she... you know?" Yao Xin asked, her eyes sparkling with mischief.
"Nothing special, just a lot of moaning," Shen Ruyu said, trying to suppress a laugh. "I sometimes thought she was being beaten up."
"Next time, have little sister record it for me," Yao Xin suggested, laughing.
"Fuck you, you bitch...Mom, what on earth did you call me for?" Yao Nan said, finally losing her patience.
Shen Ruyu's tone suddenly became serious: "Mom just wanted to talk to you about this. You are pregnant now and you have to take care of your body and can't do anything. So do you have any plans?"
"What plans??"
