Chapter10

Xu Bin glanced discreetly and noticed that his mother-in-law was still watching. He immediately sat up, adjusted their position, and had Yao Nan lie down. He spread her legs and held them around his waist.

The intimate connection between the two was exposed to his mother-in-law's view. He leaned down and kissed his wife's lips, holding her shoulders tightly. Meanwhile, he thrust his hard manhood into her wet pussy.

"Ah, honey… You're thrusting so hard!"

In the pitch black master bedroom, the sound of their panting was disordered yet subtle. Shen Ruyu peeked through the gap in the door, wide-eyed and unblinking, witnessing the scene.

In the not-so-distant distance, Yao Nan's buttocks were almost suspended in the air as Xu Bin's manhood thrust into her, eliciting satisfied moans from her. Shen Ruyu had an eagle-eyed vision from her bedroom, which she normally found annoying but now came in handy.

Xu Bin only wanted his mother-in-law to get a general idea, but he never expected Shen Ruyu to use binoculars to observe the scene carefully. The glint he saw earlier was from the binoculars.

Shen Ruyu instinctively swallowed her saliva. She could clearly see her daughter's pussy and her son-in-law's lower body, both drenched in fluids. Not only were his testicles and anus wet, but a lot of it had also flowed onto the floor. It was evident how pleasurable her daughter was.

The sound of their flesh colliding was particularly crisp and loud. Accompanied by a rhythm resembling water splashes, it resonated at a rapid frequency, intertwined with the sounds of her daughter's satisfied moans echoing through the living room.

Each thrust felt like a cat scratching, making Shen Ruyu's breathing quicken and her legs uncontrollably wet.

"Ah… Honey, you're so amazing. You're so hard…"

"The thrusts are too deep, I can't take it… Fuck!"

Encouraged by Xu Bin, Yao Nan, who had fully surrendered to her lust, no longer hesitated to moan and scream. Although her moans sounded somewhat pitiful and heart-wrenching, anyone with experience would know how pleasurable she was. Just hearing those lascivious sounds echoing in the living room made Shen Ruyu feel hot-blooded and uncomfortable all over.

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

After experiencing two orgasms from oral and traditional sex, Yao Nan felt like she was going crazy. She had never imagined that sex could be so wonderful. As she approached her second climax, Xu Bin also felt the urge to ejaculate. But when he thought about his mother-in-law watching, he became exceptionally excited and stopped himself from succumbing to that impulse.

Normally, Xu Bin lasted within 10 minutes, and sometimes he could only hold on for five minutes when receiving oral. After drinking, he could last a bit longer. But now, when he looked up, 15 minutes had passed. He couldn't help but feel that his stamina had been chosen well. With such performance, he could even consider becoming a gigolo after a bit more training.

It's over…

Seeing the two of them stop and kiss each other, Shen Ruyu's mind came up with this thought. Subconsciously, she looked at the time, realizing that half an hour had passed. She was surprised by how bold and adventurous her obedient son-in-law and daughter were, daring to make love in her bedroom.

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

Although it was their own bedroom, it felt like they were thieves. She knew she shouldn't be doing this, but she found voyeurism to be extremely stimulating. Her heart raced, and she couldn't find any reason to interrupt.

With a snap, the bedroom light turned on, illuminating the room brightly. Xu Bin saw his mother-in-law hiding behind the curtains, as her toes were visible, causing the curtains to move slightly.

Of course, he couldn't let his wife notice, or she would be ashamed. After climbing onto the bed, Xu Bin adjusted their position so that Yao Nan's back was facing the curtains.

"Honey, you're so hard… Like iron!"

Xu Bin sat on the bed nonchalantly, while Yao Nan knelt straight, taking his manhood into her mouth. With a flushed face, she looked up at her husband with adoration and murmured, "Honey, how long are you going to fuck me for?"

"First, let me enjoy the oral pleasure. Later, it will be your turn to feel good."

Xu Bin smirked with satisfaction.

Watching his beautiful wife kneeling before him, orally pleasuring him with her lips wrapped around his manhood, he felt completely fulfilled. Yao Nan, who was exhausted from their previous activities, grew tired after a while. Xu Bin signaled for her to turn around and said, "Wife, I'll take you from behind. You love this position, right?"

As he spoke, Xu Bin's fingers touched her lips. Yao Nan took them into her mouth and sucked on them. In a muffled and intoxicated voice, she said, "Yes, fuck me like that… Like a little bitch… Thrust deep…"

With that, she turned around, raised her peach-shaped buttocks, and offered herself to her husband. She looked back with a dazed expression, eagerly anticipating the upcoming storm.

Xu Bin took a step forward, held his glans against her slit, and rubbed it, making her moan. Excitedly, he said, "Wife, look at your mother's sexy clothes and lingerie…"

Yao Nan felt insecure and conservative. She always dressed modestly, even her underwear was plain. She couldn't compare to her mother, which was tragic.

Yao Nan subconsciously looked at her mother's open wardrobe. The nightgowns inside were shorter than hers, with lace and hollow designs on the lingerie, and even thongs…

"You're mean. Why are you talking about this… Ah!"

Yao Nan's speech immediately turned into moans as Xu Bin grabbed her waist and thrust forcefully. His manhood re-entered the tight and wet space, completely enveloped.

The sound of their flesh colliding resonated again, fast and intense. From Shen Ruyu's perspective, she could clearly see how her daughter was moaning like a bitch under her son-in-law.

"Next time we make love, wear your mother's lingerie…"

"You're mean. Don't… What are you thinking about my mom?"

"I'm not. Don't make things up!"

"I don't believe you. Mom has such big breasts, and you and my sister's husband always peek…"

Yao Nan, who was usually conservative and rarely moaned, had fallen completely and shamelessly under her husband's seduction. Moreover, the relaxation in their private world gave her an incredible sense of security.

As her husband thrust into her with force, she felt a mixture of pleasure and confusion. Along with her husband, she engaged in those obscene and lascivious conversations. She never thought that her mother would hear them.

"You wicked husband… I'm sure… Talking about my mom's breasts… Makes you even harder husband… It's true…"

Yao Nan's moans intensified because Xu Bin was also getting stimulated. He grabbed her sensitive breasts roughly, squeezing them and thrusting forcefully.

Each thrust went deep, and every penetration made Yao Nan cry out like she was sobbing. She could no longer form coherent sentences.

"I can't…!"

Finally, Xu Bin couldn't hold back anymore. He thrust hard, and his glans swelled even larger, pushing deep into her flower core, releasing scorching hot semen deep inside her wonderful body.

"Ah!"

Overwhelmed by an intense orgasm, Yao Nan lost count of how many times she had climaxed. Her body convulsed and she nearly fainted. Her body was as wet as if it had been fished out of water.

Xu Bin also ejaculated forcefully. Afterward, he collapsed onto her, and it took a while for him to regain his senses.

Seeing his wife almost fainted from their intense session, Xu Bin couldn't help but feel a sense of pride. He lifted her limp body and left his mother-in-law's bedroom, making sure to turn off the lights before leaving.

As soon as the door closed, Shen Ruyu's legs almost gave way. She sat on the floor.

"This rascal… I didn't expect him to be so strong!"

Shen Ruyu looked at the time and realized it had been over half an hour. Their high-intensity thrusting was simply beastly.

Her underwear was soaked… Shen Ruyu breathed lightly. She tossed and turned all night, with her mind filled with the ferociousness of her son-in-law and her daughter's lustful moans and obscenities.
