Chapter 494 – IF3. Pregnant Cow (33)

Si-woon’s eyes widen in surprise and joy when she sees Si-young entering the front door of her house, and when Si-young spots Si-woon, she smiles and waves her hand. Br〉

“Oh! Siyoung’s older sister?”

“Ahaha, hello? Siwoon.”

While the two people are exchanging greetings, Yeon-woo and Jin-seok also come out to the front door, and Si-young bows her head and greets them properly.

“Yeonwoo, Jinseok, I’ve heard a lot from you two. My name is Choi Si-young, a sex toilet belonging to the master’s professor’s office. Please, you two, feel free to use me as a sex toilet and sex slave.”

“Oh, welcome. And don’t be so stiff, just call me Yeonwoo unnie and Jinseok oppa.”

“No, but I heard that you two are on the same level as my master. How can you do that…”

Haha! I said it’s okay. By the way, she’s even more beautiful than what I heard from Dohyun? I’m looking forward to the future of this.”

“Yes, I will do my best to dedicate myself from now on. Jinseok… Oppa.”

For reference, in the main story, after Do-hyeon divorced A-young, he often took Si-young to her group’s events, so Jin-seok and Si-young were also very close at this point. However, in this timeline, divorce has become a thing of the past, and since the city practice only took place in schools, this is my first time meeting Jin-seok and his wife.

And after the three people finished greeting each other, Si-woon asked Si-young and Do-hyeon as if he had been waiting.

“But what is Siyoung doing at our house? Of course, I am most welcome!”

“Well, Yeonwoo seems to be having a hard time these days, so I called Siyoung to help her. Shiwoon, are you okay too?”

“Of course! Welcome, Siyoung noona.”

“Hehe~ Please take care of me, Siwoon.”

“Then, let me show you around my house first. Come here.”

Si-woon seems excited to be able to have sex with this pretty teaching assistant at home, so he takes Si-young’s hand and leads her into the house, and Do-hyeon, Jin-seok, and Yeon-woo also look on warmly.

And Si-woon gave Si-young a living room with a mattress where they usually had orgies,

A bathroom on the first floor where you can do enemas or play with love gel,

The first floor bedroom that Do-hyeon mainly uses,

Also, there is a warehouse storing adult products on the first floor,

And her own room on the second floor,

A second-floor bathroom that can be used when the first-floor bathroom is in use,

It was originally Seha’s room, but now Jinseok mainly uses it as a guest room.

It also guides you through every corner of the house, including the kitchen, laundry room, etc.

And since it is dinner time, Yeon-woo begins to prepare a meal, and Si-young follows her into the kitchen and begins to help Yeon-woo. However, Yeonwoo also praises Siyoung because her skills are quite good.

“You must be busy studying or working as a toilet, but your skills are pretty good~”

“Yes, since I live at school, I cook meals often.”

Unlike regular graduate students, the students are installed at the school and stay there for a long period of time, so they have a separate room similar to a dormitory so that they can get their lodging there. Siyoung also stayed there, practically becoming a monk, and her parents treated her as if they had married her off to a far away country.

Anyway, after finishing preparing the meal, the five of us, including Si-young, share a meal together, and Si-woon asks a question.

“But will the people at the graduate school be okay if Siyoung comes here? “I can’t deal with my sexual desires because I don’t have a sister.”

“That’s okay. After all, our department does not have the only toilet equipment available. So, if there is a vacancy in one room, you can merge with another room and have an orgy. Right, Siyoung?”

“Yes! Not long ago, a colleague from another room was away, and I was also raped by the people in that room. At that time, the work doubled, and it was quite difficult, but of course it was just as much fun.”

“Hey~ I see.”

As Do-hyeon said, professors often take the toilet equipment belonging to them home, and sometimes take them to parties or seminars to serve. And at that time, it was common for Si-yeong to use the restroom as if he were a child, so it wasn’t particularly difficult for Si-yeong to come to Do-hyeon’s house like this. Moreover, compared to other professors, Do-hyeon rarely brings Si-young out, so even if he brings Si-young out for a few days, the other rooms won’t be able to complain.

“So, Siyoung decided to come occasionally and stay for 2–3 days until Ayoung and Seha return. So, where should Siyoung’s room be?”

“That’s right, we’re using the guest room right now.”

“Shall we prepare another room?”

In fact, during an orgy, there are many times when they sleep together in the living room, and sometimes Yeon-woo sleeps with Jin-seok in the guest room, but there are also times when she sleeps together in Do-hyeon and Si-woon’s room. And even if Siyoung is added here, things will proceed similarly, but since there needs to be a place to store Siyoung’s luggage, a room must be selected first. In fact, the luggage that Siyoung brought was the size of a small suitcase, so it was quite bulky.

So, Yeon-woo proposes to organize the unused room or the room used as a storage room, but Si-woon raises his hand and shouts.

“Me! Then Siyoung will live in my room with me!”

“What? Siwoon in your room?”

“Huh! “It’s okay because Siyoung has room to store her luggage.”

“Hmm… I guess Siyoung will sleep with men eventually, so there’s no need to prepare another room. Siyoung, are you okay with that?”

“Yes, it’s okay for me to live in the bathroom if it’s my master’s order.”

“Haha! “Do we really have to go that far, then will Si-woon do as he says?”

“Ahh, it’s done!”

When Do-hyeon gives permission, Si-woon also clenches his fists and says he likes her. However, Si-Woon’s excited attitude may seem a bit flashy, but in fact, to Si-Woon, Ah-Young, Yeon-Woo, and Se-Ha are all seen as family, like a mother, aunt, or older sister.

Plus, he hasn’t brought his girlfriend yet, so this is Si-un’s first time living with a woman outside his family. In addition, compared to Hye-rim in the main story, Hye-rim is Si-woon’s girlfriend, but Si-yeong is not his girlfriend but her father’s sexual slave who can be treated well, so the attitude towards her cannot be the same.
So, when it was decided to live in Si-woon’s room, Si-young glanced at her luggage that she had not even unpacked yet.

“Then, after eating, I’ll go to Siun’s room, unpack her luggage, and come down.”

“Hmm~ Now that you say that, it seems like the two of you are living together in Siwoon’s room.”

“Well, it may only last for a few days, but living together is living together. Siwoon, it would be nice to live with such a pretty sister.”

When Si-woon and Si-young hear the adults teasing them like this, their faces turn slightly red and they feel embarrassed. And when she finished eating, as mentioned earlier, Siyoung picked up her luggage and followed Siun up to Siun’s room on the second floor.
For reference, the desk in Shiwoon’s room is horizontally long, with chairs moving from side to side, half of which is used for studying, and half of which is used as a computer desk. But now, for Si-young, she puts her monitor to one side so that Si-woon can use it, and gives the other half to Si-young to use. And when we bring in another chair for her, it quickly turns into a desk for two.

“And I’ll empty this drawer for your clothes, so you can put them here.”

“Yes, thank you Siu… Hmm!?”

“Jup~ Jjub♪ Jjuup~ Jjub! Wow! Jjuup♪”

Before Siyoung can finish her words of thanks, Siwoon pounces on her, pushing Siyoung against the side of her desk, which leaves Siyoung almost on top of her, and she kisses Siwoon passionately. Share. And after a welcome kiss, Si-woon kneads Si-young’s thighs with sticky hands and crawls up near her pussy, and Si-young catches him and stops, making him feel embarrassed.

“For a moment! But first, get permission from the owner~”

“Tsk, your sister is your father’s first, right? Okay.”

Although Si-Woon is jealous, it is thanks to Do-Hyeon that he and Si-Young are able to do this together, so for now, he does not follow Si-Young’s words and goes as far as having sex. However, the two only break up after enjoying the kiss a little longer, and Si-young roughly packs up her things and takes off all her clothes in front of Si-woon before changing into other clothes.

And when Si-woon and Si-young change into the clothes they wear when volunteering at graduate school and are easy to take off and be violated, they come down to the first floor, where three other people are already preparing for an orgy.

“Oh~ are you here? “Then shall we start right away?”

“Master. But I’m not ready for the anal vagina yet. Can you wait a little while? “I’ll take care of it quickly and come back.”

“That’s okay, so just come. Since Siyoung hasn’t had sex with Jinseok yet, we decided to start one-on-one with Jinseok. So, I’ll just use the vagina at first, so it’s okay to do the enema afterward.”

“Oh, I see. Okay.”

Si-young and Si-woon were in a very sweet and pleasant mood until just now, but since it is her first time with Jin-seok, she decides to start with Jin-seok. And if that’s the reason, he understands with an expression that there is nothing he can do, and he climbs on the sofa with Do-hyeon and Yeon-woo.
Then, Jin-seok and Si-young got on the mattress, sat close to each other, and started the engine while slowly caressing each other’s bodies. And with this, Siyoung came as a helper and the first orgy began.
