Liu Yizan after doing the first forceful Thrust, didn't stop there as he continue doing the same thing again and again in the same pace.
He pull out his d*ck and then thrust in her with force.
After doing it slowly for some moments, he started to quicken his pace slowly and started to ramming her with his d*ck even more forcefully.
Liu Xianwei could do nothing but respond to him in kind, as she also started moaning loudly.
" Yeah~ Ah~ AHH~ Fuck me, Fuck me hard my dear little Yizan~~~"
She continued to moaned loudly and told him to continue fucking her.
Liu Yizan, hearing her lewd voice got even more horny and started to ram her with his d*ck even harder and faster.
* Squelch* Squelch* Squelch*
*Clap*Clap*Clap*Clap*Clap*
The sound of Squelching came out because of the friction of his d*ck and her wet p*ssy, also the sound of clapping came from his pelvis hitting her ass cheeks, were resounding loudly in the room.
From the creak of the door, a pair of eyes can be seen watching the scene that was going in the room while the person's hand was in her p*ssy. " Haah~, Yeah, Fuck that bitch~ Fuck your sister in law son, make her cum and cum inside her~."
The person was none other than Lui Yulan, Lui Yizan's mother and Liu Xianwei's mother in law.
Currently she is watching the first night of her son and her daughter in law, while masturbating as she enjoyed the scene.
She was going to sleep like normal person tonight, but as she went to sleep she started to hear moans of Liu Xianwei coming from this room.
This room was just beside her room which made it easy for her hear what was going on in this room.
There was no such thing as sound proofing system in their small house.
The sound of clapping and squelching can be also heard at her room.
And seeing the way her daughter in law is moaning by getting fucked by her son. Liu Yulan also started to desiring for the same treatment from her dear son.
The background sound of her Daughter in law's moaning, her son's grunts, the sound of squelching and finally the sound of clapping, that was resounding in the room made her even more horny.
Just how much she wish to join them and kiss her son while he is busy fucking his sister in law.
But she doesn't have the courage to do that.
If they came for her and ask for her to join them, then she won't decline their offer, but she doesn't have the courage to ask them.
The reason why she arranged both of their marriage was because, she knew about their fantasies for each other and also for her.
She had seen both of them masturbating while calling out her.
Seeing those situation also made her started to fantasize about them, now seeing her dear son going in and out of that beautiful and sexy, daughter in law's p*ssy, just made her more and more horny.
She had seen how he licked her p*ssy, at that time, she really was thinking about just joining them and letting him lick her p*ssy too.
Which mother won't like to have her son eat her.
Inside the room, the sex was still going on as Liu Yizan continued to fuck Liu Xianwei hard.
This continued for straight 20 minutes after which both Liu Xianwei and Liu Yizan let out a loud moan as they climaxed simultaneously.
Liu Yizan didn't pull out his d*ck, instead he came inside her and pumped his semen directly into her womb.
Liu Xianwei also orgasm with him as he filled her up.
This was her Fourth orgasm that she was having after he started fucking her with his d*ck.
She never thought that he would last for this long and that wasn't all, with each orgasm she released, she started to get more and more sensitive.
Which made it hard for her to not orgasm again as he continuously fucking her.
*Spurt*Spurt*Spurt*Spurt*Spurt*
The sound of Semen gushing out, came from Liu Xianwei's p*ssy.
Liu Yizan, seeing the amount of semen he was releasing in her pussy become dumfounded and bewildered.
Rather than releasing semen, he felt like he was peeing instead, by how the semen was gushing out of his D*ck inside her womb.
The Quantity was too much for Liu Xianwei's p*ssy to hold.
Which made most of the semen gushed out of her p*ssy and fall onto the floor.
' Is this amount even biologically possible?' He asked himself as he look at the amount of semen that was gushing out of her p*ssy and falling on the ground.
It was like the scenes from those hentais he use to watch in his past life.
It was totally unrealistic but it is happening before his very eyes and he is the one who is doing it. It's unbelievable but he can't deny that it's real.
' It's seems to be the doing of the system, as this never happened when I masturbated in past.' Liu Yizan thought as he continued to release his semen inside Liu Xianwei's p*ssy.
After coming for close to 2 minutes, it seems his semen tank was finally out of semen.
He pulled out his semi hard dick from her p*ssy slowly, which let the semen that he was blocking inside her also came out from her p*ssy, with some spurting noises, which made a puddle of semen on the ground.
As his sister in law lost the support of his hands that was holding her waist, she fall down onto the bed with her face first.
The low sound of his semen coming out of her p*ssy can be heard in the room, she was very tired after that long sex.
Even though it's been only less than 45 minutes of sex session, if she also include the foreplay they did before.
She felt like he was fucking her for years and that was just too amazing, but also tiring as she had more than five orgasm in just this one session.
As Liu Yizan look at her backside and show his cum dripping from her p*ssy like jelly, his semi hard dick started to get erect again.
Seeing this Liu Yizan became surprise and thought, ' Did the system made me into some kind of sex beast?'
Liu Yulan who was outside looking at the scene while masturbating became shocked by seeing his dick getting erect again after all those fucking.
Now she really just want him to fuck her to his heart content and overflow her pu*ssy like how he did with his sister in law.
She doesn't know how much semen most man releases as she had been only with Liu Yizan's father and he didn't let out much of a semen like how much her son produced, forget about this amount, she even hardly felt him cumming inside her.
But seeing the amount of semen that her dear son has released inside his sister in law's p*ssy, She is sure that if she put an empty glass under Liu Xianwei now, she would still able to fill the whole glass to the top with his semen.
If she add the semen that is spilled on the ground than she might able to fill one big bowl with that much amount of semen.
Liu Yulan become hungry thinking that and said to herself as she look at her daughter in law's cum dripping p*ssy, " Ahh~ I want to drink that semen of my dear son from that slutty p*ssy."
She put two fingers inside her p*ssy, as she continued to finger fucking her while fantasizing about how good it would feel to getting that amount of semen inside her p*ssy by her dear son.
Liu Yizan, seeing his sister in law already tired but his d*ck still hard thought about what he should do now.
But in the end, he refrain from fucking her again after thinking for sometime.
He instead, put his d*ck inside her p*ssy again, which made Liu Xianwei let out a moan of pleasure.
Then he pushed her to get on the bed with his hips.
After both of them were on bed, they went for a sleep.
Though they were naked and the smell of sex was coming from them. They didn't go for taking shower.
Instead, Liu Yizan, let his d*ck remain inside her, he put his hand around her other side and pull her in his embrace from the side.
Then he gently squish her boobs while slowly fucking her as he said, " Let's sleep."
Saying that he kissed her on the ear while his movements of hand and pelvis didn't stopped.
Liu Xianwei, already had her eyes close, was enjoying his touch but was too tired to moan or do something anymore.
She only slowly hump backwards as she said, " Sleep well." After that she said nothing but continued her motion.
Liu Yizan closed his eyes too and didn't said anything.
After 10 minutes, both of them fall asleep, while their lower body still moving gently.
Liu Yulan, who saw this got up and went inside the room.
She went at the direction of their heads as she pull up her night dress and made her cum dripping p*ssy, visible to their faces but both of them were already sleeping.
She rubbed her p*ssy for some time, then put two fingers inside her p*ssy.
After finger fucking her for some time in front of her son and daughter in law, she took out her fingers.
Then she gently put one knee on their bed and move towards her daughter in law.
After she came close to them, she pushed her cum dripping fingers inside her Daughter in laws open mouth.
She rubbed them inside her mouth for sometime and even touched her slimy tongue with her cum dripping fingers.
Then she pulled them out, put those fingers into her p*ssy again and started finger fucking with those fingers which were in Liu Xianwei's mouth.
Then she again took out those fingers from her p*ssy and now put those fingers in Liu Yizan's opened mouth and did the same things she had done with her daughter in law inside her son's mouth.
After taking out her fingers from his mouth, she put them inside her mouth and stared sucking them.
After having her fun, she got down from the bed, adjusted her attrite, and went back to her room.
She masturbated once after going back, thinking about the scenes she had watched tonight.
Then after having her climax, she went to sleep.
