Chapter 10

Xu Bin glanced discreetly and saw that his mother-in-law was still peeking. He immediately sat up, holding his wife and adjusting their position so she could lie down, with her legs spread apart on his waist.

The intimate connection between the two was exposed in front of his mother-in-law. He then lowered his head and kissed his wife's lips, holding her shoulders while thrusting his hard penis into her vagina again and again.

"Ah, husband…thrust harder!!"

Inside the pitch-black master bedroom, the sounds of gasping were chaotic yet subtle. Shen Ruyu peeked through the crack of the door, widened her eyes, and watched this scene without blinking.

Nearby, on the floor, Yao Nan's buttocks were almost suspended in the air as Xu Bin's penis thrust into her fiercely, eliciting satisfied moans from his daughter.

In the master bedroom, there was a telescope that Yao Baichuan had brought from somewhere. Shen Ruyu had always disliked it and planned to throw it away, but she didn't expect it to come in handy now.

Xu Bin only wanted his mother-in-law to have a general idea, but he never expected that Shen Ruyu would carefully observe using the telescope. The glint just now was a reflection from the telescope.

Shen Ruyu subconsciously swallowed her saliva because she could clearly see that her daughter's vagina and son-in-law's lower body were wet. Not only were his testicles and anus covered in moisture, but a lot had also flowed onto the floor, indicating how pleasurable her daughter was feeling.

The sound of flesh colliding was particularly crisp and loud, accompanied by a rhythm that sounded like splashing water, at a fast pace. In addition, the satisfied moans of his daughter echoed throughout the room.

Each thrust felt like a cat scratching, making Shen Ruyu's breathing become rapid and her legs unconsciously wetting her underwear.

"Ah…husband, you're so good…so hard…"

"It's too deep, I can't handle it…fuck!!"

Encouraged by Xu Bin, Yao Nan was also immersed in lust. She no longer tried to hide her moans and called out in satisfaction.

Listening to the sounds, which were both mournful and heart-wrenching, anyone with experience would know how pleasurable she was feeling. Just listening to these lascivious sounds echoing in the living room made Shen Ruyu's blood boil, and she felt extremely uncomfortable all over her body.

"Husband…I'm coming again, I'm coming again!"

After experiencing two orgasms from oral sex and two from traditional intercourse, Yao Nan felt like she was going crazy. She had never imagined that sexual pleasure could be so wonderful.

When she was about to reach her second climax, Xu Bin felt the urge to ejaculate, but he resisted it because he didn't want his mother-in-law to find out. He stopped to ease the impulse.

Originally, Xu Bin was a quick finisher, lasting no more than 10 minutes. Sometimes, he couldn't even last five minutes when receiving oral sex, and only after drinking could he last a bit longer. But now, when he looked up, it had been fifteen minutes. He couldn't help but feel that his stamina was really good, and he could easily become a male escort with such performance.

It's over…

Seeing the two of them stop and kiss each other, Shen Ruyu had the thought that her telescope had come in handy. She involuntarily looked at the time and thought that her son-in-law was quite impressive in this aspect.

But at this moment, Xu Bin slowly pulled out his penis, and as he pulled out, it twitched. Shen Ruyu's first thought was that he was still hard after ejaculating.

"Husband, you haven't ejaculated yet…!"

Yao Nan moaned weakly, and this sentence struck Shen Ruyu like a thunderbolt. She was astonished at the possibility.

If it were Yao Baichuan… Shen Ruyu carefully recalled her sexual experiences from many years ago. If it were her own husband, he wouldn't be able to last even two minutes with such a high frequency of thrusting, but her son-in-law lasted nearly twenty minutes.

At this moment, Xu Bin princess-carried Yao Nan and said with an evil smile, "Wife, let's continue in Mom's room!"

"No, don't, what if we get caught? Let's go back to our room!"

Yao Nan, with her shy and timid personality, combined with her mother's lasciviousness, naturally felt restless and uneasy.

"It's fine, there's plenty of time, and Mom isn't home, so how could she catch us."

Saying this, Xu Bin walked towards the master bedroom, and Shen Ruyu was startled. She didn't expect her meek son-in-law and daughter to be so bold and adventurous, daring to come to her bedroom to make love.

In a panic, she wanted to hide. She didn't want to make any noise by going into the closet, so she hurriedly hid behind the curtains. Due to the long distance, she didn't have time to think.

Even though it was her own bedroom, it felt like committing a crime. She knew it was wrong, but she also found the voyeuristic act thrilling. In her anxious state, she couldn't find any reason to interrupt.

With a bang, the bedroom light turned on, illuminating the room brightly. Xu Bin immediately saw his mother-in-law hiding behind the curtains because her toes were visible, and the curtains were moving slightly.

Of course, he couldn't let his wife discover this, or she would feel extremely embarrassed. After climbing onto the bed, Xu Bin adjusted their position so that his wife's back faced the direction of the curtains.

"Husband, you're really hard…as hard as iron!"

Xu Bin sat on the bed in a carefree manner while Yao Nan knelt and started to perform oral sex on him. With a flushed face, she looked up at her husband with adoration and murmured, "Husband, how long will you keep fucking me…"

"First, let's enjoy the oral sex. Later, you'll have pleasure too."

Xu Bin proudly laughed.

Looking down at his beautiful wife kneeling and performing oral sex on him, her rosy lips wrapped around his penis, he couldn't help but feel satisfied. Any man would be content with a submissive woman like her.

Yao Nan became weak and tired after a while of oral sex. Xu Bin gestured for her to turn around and said, "Wife, I'll fuck you from behind. You like this position the most, right?"

Saying that, Xu Bin's fingers touched her lips, and Yao Nan sucked on them. Indistinctly, she moaned, "Yes, fuck me like that…just like a little bitch…thrust deep…"

As she spoke, she willingly turned around, raising her peach-like buttocks for her husband to enjoy. With a dazed look, she eagerly anticipated the upcoming storm of pleasure.

Xu Bin took a step forward and rubbed his glans against her wet vagina, making her moan. Excitedly, he said, "Wife, look at Mom's sexy clothes and lingerie…"

Yao Nan was insecure and conservative, always dressing modestly, even in her underwear. She couldn't compare to her mother, which was a tragedy.

Yao Nan subconsciously looked at the open wardrobe of her mother. The nightgowns inside were shorter than what she usually wore, and the lingerie had lace and hollow designs. There were even thongs…

"Nasty, why are you saying this…ah!"

Yao Nan's voice immediately turned into moans. Xu Bin grabbed her waist and thrust forcefully into her, his penis engulfed by her tight and wetness.

The sound of thrusting once again filled the bedroom, fast and intense. From her mother-in-law's perspective, she could clearly see how her daughter was writhing like a bitch under her son-in-law.

"It's not good…"

Finally, Xu Bin couldn't resist anymore. He pressed his body against hers, and his glans, which had swollen even larger, penetrated deep into her core, releasing scorching semen.

"Ah!"

Overwhelmed by an intense climax, Yao Nan lost count of how many times she had experienced it. Her body convulsed, and she almost fainted. Her body was as wet as if she had just been pulled out of water.

Xu Bin also ejaculated forcefully. After ejaculating, he collapsed onto her body, taking a while to regain his senses.

Seeing that his wife was almost fainted from being fucked, Xu Bin couldn't help but feel proud. He lifted her soft and limp body and left his mother-in-law's bedroom, not forgetting to turn off the light before leaving.

In the instant the door closed, Shen Ruyu's legs almost gave way. She sat on the floor, feeling weak. This night was restless, and her mind was filled with images of her son-in-law's ferocity and her daughter's lustful moans.
