Chapter 420 – IF 1. What if I Met My Mom… (2)

As mentioned earlier, while A-young was pregnant, Yeon-woo and Jin-seok came to Do-hyeon’s house every night, and while Yeon-woo was having a threesome with the two husbands in the middle, A-young was next to her, using her mouth or hands. So we had sex in a way that helped.
However, if things continued like this, Se-ha would be left home alone every night, and after a few days, she said that she didn’t want Se-ha to be lonely, and she followed him to Do-hyeon’s house. And while the parents mostly had orgies on the first floor, Seha spent time watching Siun study in Siun’s room on the second floor or rolling around on Siun’s bed.

Now, he sits side by side with Si-woon and watches him study, and as Jaewon entered K University, a prestigious university, he is also good at teaching Si-woon.

“The formula itself is important here, but it is easy to memorize the positional relationships by drawing a triangle on plane coordinates.”

“Um… Haha, I have no idea what you’re talking about.”

“Hey, you idiot!”

– Bean! –

Despite Se-ha’s efforts, Si-woon smiles brightly and throws away the knowledge, and Se-ha feeds Si-un’s forehead a little honey balm. However, as Si-woon touches the spot where she was hit, she makes excuses as if she is also wronged.

“How can you concentrate when mom and dad are having sex like that on the first floor? If you stay still, you can hear everything!”

“Don’t make excuses! “I passed the exam by studying while listening to my mom and dad having sex every day, right?”

Seha has a somewhat strict attitude when teaching her to study, but it is true that there is a difference in the sound made when only a couple is having sex and when they are having an orgy, so Seha is also secretly worried about the work on the first floor.

So, Se-ha hides the fact that she is itching and speaks condescendingly as if it is for Si-un’s benefit.

“Then, shall we cool off by doing something sexy for a while?”

“Huh! “It’s perfect because it’s been 2 hours since I did it earlier.”

“Okay, come here. Side~ Side~ Whoop! Joo~ Joobob♡”

“Haup~ Uup~ Jup~ Jup~ Jupup~”

Then, the two stopped studying and sat in front of their desks and started hugging and kissing each other. And it’s not a cute bird kiss between kids, but a deep kiss between adults with tongue and saliva. The two started kissing like this not long ago when Seha started watching him study. However, it doesn’t specifically say that the two are dating, it just feels like they are childhood friends and similar siblings who help each other unleash their sexual desires.

One more point for reference: unlike the main story, the situation has changed and Se-ha is still a virgin. In the main story, by this time, A-young had already divorced and left the house, so Se-ha was installed in this house as Do-hyeon’s sex toilet, so all the holes were already eaten, and she was being trained, but in this timeline, A-young was not divorced, so Se-ha This is because there was no need to come to the toilet.

Thanks to this, Se-ha was able to kiss Si-woon before Do-hyeon, and the dirty play between the two did not end there.

“Then shall we take a quick step back and study again?”

“Yes, I will send you a cool day too.”

– Clatter~ Clatter~ –

Meanwhile, the two people each prepare with familiar hands, taking out onaholes, love gels, and quail egg-like vibrators. Then, the two of them sit down and take off their pants and skirts to expose their lower bodies. Si-woon’s dick is already erect and Se-ha’s pussy is wet, so the front of her panties is damp. So, the two continued kissing again, with Si-woon masturbating Se-ha’s vagina with a vibrator and Se-ha masturbating Si-woon’s dick with an ona-hole.

– Ji-i-ing~ Tsu-fuk~ Tsu-fuk~ Tsu-fuk~ –

“Huh!? Siwoon is doing pretty well now, right? “Ah!”

“Yeah, I think I know how to do it now. Side~ Side~”

“Chup~ Chup~ I can’t lose, it’s a contest to see who lets it go first!”

However, the two of them did not go as far as having sex or fellatio, and after reaching a refreshing climax by giving each other a good job, they concentrated on studying again.

.

After another few months, Ayoung became fully pregnant. And she has already started producing breast milk. Considering that pregnant women usually wait about 3 days after giving birth, she is giving birth quite quickly.
However, her partner, Ayoung, said as follows, and she ignored this issue as well.

“But it was like this with Si-Woon, and Yeon-Woo also came out with breast milk before giving birth, right? So it doesn’t matter.”

Of course, not only Ayoung, but also Yeonwoo and all the surrounding women are producing breast milk at full term before giving birth, so maybe this is normal in this world.

Anyway, now that Ayoung has started producing breast milk, there are a few things that have changed from before. First, at this time, Siwoon is focusing more on studying for the exam, so Ayoung is still focusing on supporting her son, Siwoon.
But…

“Son, drink a cup of coffee and do it.”

“Yes, thank you, Mom.”

Si-woon pauses while studying hard and takes a sip of the coffee that A-young brought him. When he senses a deeper flavor than before, he smiles brightly and asks.

“Is this coffee mixed with mom’s breast milk?”

“Ahem~ Of course, my mom invested some breast milk to help my son study!”

As the two said, this coffee is none other than coffee made with Ayoung’s breast milk. If café latte is a mixture of coffee and milk, is this coffee mixed with breast milk, so to speak, “Breast milk latte”? Well, to be exact, café means coffee, and latte means milk, but they are delicious, so anything is fine.

Anyway, Si-woon also replenishes his energy by enjoying coffee filled with mother’s sincerity and nutrients, and before he knew it, A-young’s breast milk was giving Si-woon a great help in studying for the exam.

And at night, Ayoung also actively participates in the orgy, and before she starts the orgy in earnest, she starts off with breastfeeding play.

“Hrup~ Gul~ Gulp! Gulp! As expected, Ayoung’s breast milk is delicious, although it’s not as good as our Yeonwoo’s.”

“What? Jinseok, why are you complaining about drinking someone else’s wife’s breast milk? If you don’t like it, don’t drink it. Gulp~ Gulp~ Gulp~ Gulp~”

“Huh! Both of you, drink in moderation. If this continues, Si-Woon won’t even have any breast milk left to add to his coffee. Hehe♡”

Do-hyeon and Jin-seok bite on one of A-young’s nipples from each side and suck her breast milk, and while A-young grumbles at the men who have become her babies, she hugs their heads with both arms and caresses them with her maternal love that has increased significantly these days.

And when the feeding play is over, the men lay Ayoung on her side so that more of the burden can be placed on Yujin, who is still in Ayoung’s womb. Then, they lifted one thigh and supported it stably on their bodies, and Jinseok started thrusting his dick into Ayoung’s pussy and Dohyeon’s dick into her anal vagina from both sides simultaneously.

– Pow! Puck! Puck! Crack, crack, crack! Puck! –

“Keuw~ Even when you’re pregnant, Ayoung’s pussy is so full of water. In fact, it seems like her sex drive has increased even more than before?”

“Still, be careful, because if it’s amniotic fluid and not love fluid, we’ll be X. So, control your strength well. “Help~”

“Ugh♡ Ugh~ Ugh~ Ha! Ahhh!!!”

The men thrust their dicks persistently and tantalizingly, but not too hard so as not to put a strain on Ayoung and Yujin. In the meantime, Yeonwoo takes care of Ayoung by checking her condition.

“Ayoung, are you okay? “Isn’t that a bit excessive?”

“Shh… It’s okay, doctor Sansaeng said this level of exercise is okay.”

“Well, then it’s okay, but if you think it’s too much, tell me right away, okay?”

Yeon-woo urges her to do so, and she participates in the orgy to reduce the burden on A-young. So, she kneels behind the men and takes turns sucking her anus, and once again gives her pussy to the men, giving Ayoung some time to catch her breath.

And the men joke with Ayoung and Yeonwoo as they take turns thrusting their dicks into her pussies.

“Haha~ By the way, our Eugene received a very strong prenatal education from her mom and dad’s orgy.”

“I know. What if I’m born as a lewd girl who looks exactly like Ayoung or Yeonwoo?”

“Whatever, it’s a huge windfall. Well, it will be a story that takes place in the very future, after Eugene becomes an adult.”

“…”

As Do-hyeon and Jin-seok have sex with A-young’s vagina, which contains Yu-jin, they are already wishing for something to happen 20 years later. Even though it happened after Yu-jin became an adult, A-young listens to it because she is Do-hyeon’s half-blood sister. It’s a complicated feeling in many ways. But for now, it’s too late, so Ayoung focuses on her current sex, and this time, the men feed her by excreting semen into Ayoung’s mouth, adding nutrients to her.
And instead of supplying her with semen, the men sucked both of A-young’s nipples, which had just begun to produce milk again. Unlike before, A-young was in a very sensitive state and quickly urinated on her front.

“Huh! Wait a minute, I’m getting sensitive now… Wow!”

– Shoot~ Shururururururut~ –

“Haha, our Ayoung is crazy, getting wet on top of her and peeing on top of her. Gulp! Gulp! Gulp!”

“Yeonwoo, please clean up below. Whoop~ Jjung! Wow! Churrup~”

“Yes~ Yes~ Hehe, they are really perverts. Even if you are pregnant, they won’t take care of you.”

So the four people continued the orgy, faithful to their respective roles, without noticing that someone was spying on them.

“Wow… Mom and Dad are really cool.”

“Shh! “Don’t make a sound, you’ll get caught!”



It’s Si-woon peeping through a crack in the door, and unlike the main story where he was peeping alone, this time Se-ha is there too. And the two silently watched the parents’ promiscuous sex, and Si-woon in particular saw her mother, A-young, being returned to her fathers with a large pregnant belly, sucking her breast milk, and even urinating.

Then, the two sneaked back up to the second floor before their parents caught them, and while spying on the orgy, they gave each other their horny cocks and pussies. They were both so excited that they each went away 2–3 times in a row. Only then did I finally calm down.
