Chapter 201 – 29. Negotiation (1)

To briefly summarize the events of the past year, Seha came to Do-hyeon and Si-woon’s house and first developed herself as a woman by having sex with Do-hyeon. She also became a member of the group and expanded her range of interactions with other men.

And starting from Si-woon’s birthday this year, I started having sex with Si-woon, and this time, I had sex with both Do-hyeon and Si-woon at the same time and even got both nipples pierced by them.

So, when Seha was only used by Do-hyeon, it was half-baked, but now that it is used by Si-un, it has become the true meat toilet of this house, both in name and reality.

And looking at this structure, it is similar to the past when Se-ha’s mother, Yeon-woo, lived together in Tae-hyuk and Do-hyeon’s house as a sex slave, but there is a big difference from then. That’s because Yeon-woo was Tae-hyuk’s slave, but Tae-hyuk lent it to Do-hyeon, and later on, Yeon-woo was Do-hyeon’s slave, but lent it to Tae-hyuk, so the master-slave relationship was focused on one side.

However, right now, Seha is not a slave, but is installed in this house as a toilet, so Do-hyeon and Si-woon are given equal rights to use it.

So Si-Woon takes the risk and falls first.

“Isn’t it too disadvantageous for me as it is now?”

“Huh? What else? Hmm♡”

“No, right now, Seha is mostly living with her father in the master bedroom. Then it’s much easier for dad to have sex.”

“Oh, that? Ugh!!!”

“Tsk! That’s definitely true.”

Both Seha and Dohyeon nod their heads as if they understand what Siun said.
In fact, when Se-ha first came into this house, Do-hyeon properly prepared Se-ha’s room on the second floor. However, the number of times Seha actually slept or lived in his own room was only a handful. For nearly a year, Do-hyeon and Se-ha have been rolling around on the bed together in Do-hyeon’s master bedroom, so they have practically been living like newlyweds.

So, almost all of Seha’s frequently used items have been moved to the master bedroom. So, if your living area is centered around Do-hyeon’s living room, it is inevitable that you and Do-hyeon will come into contact with each other more often.

In fact, even now, as soon as Se-ha and Do-hyeon wake up, they are sitting on the bed and having sex on their backs to deal with their morning erections, and Si-woon is sitting on the chair next to Do-hyeon, who is sitting on the bed, and is sitting on top of Se-ha, who is being lifted by his cock. I was grunting while watching my chest bouncing up and down.

“Anyway, it’s unfair if it continues like this. “I ask that something be done.”

“That’s… No… Ugh!? Si-woon, wait a minute, I’ll leave now… And we’ll talk later… Haaaaa!!!♡”

– Sigh! Churrrr! –

Unfortunately, at this time, the conversation is cut off because Se-ha climaxes, and at the same time as Se-ha climaxes, a stream of exhausted urine spurts out like a water gun and shoots directly into Si-un’s legs, soaking them with hot water. As Se-ha’s body and chest twitch and twitch as she walks away, the piercings that Do-hyeon and Si-woon made on both of Se-ha’s nipples also reflect the light and sparkle.

Si-woon then sees this and gets even more upset, but he knows that Se-ha, who is concentrating on going as he is, won’t be able to hear him, so he keeps his mouth shut for a moment. Then, unlike Se-ha, Do-hyeon, who has not yet ejaculated, grins at his son, and when Se-ha’s climax subsides a little, he pulls out his cock and changes his position a little.

“Seha, will you lie down and give me a blowjob? And Siwoon, please fuck me from behind.”

“Ah, yes~”

“…”

Although Si-Woon has a pouting expression, when Se-Ha gets off the bed, stands on both feet, lowers his upper body, and sticks out his butt, he obediently sticks his dick in there. Then, Seha stands on the bed with both hands and serves his father Do-hyeon’s cock with his mouth pussy, and accepts his son Si-un’s cock with his front pussy, and works hard as a sex toilet from the morning.

For reference, the reason Do-hyeon and Si-woon didn’t do the sandwich position back and forth was because they had just woken up and Se-ha hadn’t administered the enema yet. So, for morning sex, only the mouth and vagina are used, and Do-hyeon and Si-woon ejaculate in the same holes they were using.

“Sigh! Sister, I’m going to cum!”

“I’m coming too! Please drink it all!”

“Hmm!”

– Pewfew! Wow,~ Wow! Pewpot! –

“Huh!? Eup… Ugh~ Ugh! Gulp~ Gulp~ Gulp~ Gulp~ Puha♡”

Seha feels the semen exploding from the vagina below and spreading to the uterus, while above she drinks all the first, richly scented semen.

And, feeling sticky all over his body, he tries to sit down, but before he can, Si-woon quickly intercepts Se-ha’s body and hugs her tightly, saying,

“So, let’s make a deal about either sleeping in my room tonight, or sleeping together in the living room!”

“Hmm~ Then what should I do with this~”

Going back to the story from before, this time, with Si-woon joining in on the sex, both Do-hyeon and Se-ha really got fired up. So, as I said above, right now, Do-hyeon, Si-woon, and Se-ha are like newlyweds who are instantly switched on and have sex as soon as their eyes meet. However, it is true that Se-ha shares the same room with Do-hyeon and sleeps together at night, which is absolutely at a disadvantage to Si-woon.

So, while Do-hyeon and Si-woon were groaning and thinking over and over again, Se-ha managed to come to her senses and got out of Si-woon’s arms and stood up and spoke.

“Haha~ Haha~ Anyway, if we keep going like this, everyone will be late for school. Let’s each think about it first, then we’ll talk about it in the evening when we return from school.”

“Oh, that would be a good idea.”

“Okay.”

And the three begin to prepare to go to school as professors and students, respectively.

First, the three of them finish the breakfast prepared by Seha, and then Dohyeon speaks to Seha.

“Seha, haven’t you done the enema this morning yet? Shall I help you?”

“Yes, I would appreciate it if you could.”

As Seha now completely uses the anus as a sexual organ, she began to use enemas every day, and as a result, it became a routine for her to vomit with an enema once a day after breakfast. As a result, constipation no longer had anything to do with Seha, and it was also good for beauty, so my skin was getting even better.

But this time, Si-woon grumbles and puts the brakes on.

“Tch, I also wanted to give my sister an enema.”

“Hehe~ Siwoon, you can do it later in the evening. Because you will come earlier than Do-hyeon anyway. “Understand, right?”

“Well, that’s enough.”

Seha prepares for sex at night by giving an enema like this, except once in the morning and again before having sex in earnest after dinner. So when Si-woon, who made the reservation, finally shows signs of understanding, Se-ha lets out a small sigh.

“Ugh~ I can’t live because of the men in this house.”

Originally, Se-ha could do this alone, but as Do-hyeon and Si-woon became more competitive, Se-ha was no longer able to leisurely watch the big day alone for a while. And right now, being led by Do-hyeon’s hand, they went into the bathroom together, and soon Se-ha’s sweet voice and the strong sound of the waterfall rang out to Si-un’s ears outside the bathroom door.

And after a while, Se-ha comes out of the bathroom with a refreshed face, and she asks Do-hyeon.

“Ah, Mr. Dohyun. “Can you give me a ride today?”

“Okay, since the time is right, let’s go together.”

Since Do-hyeon and Se-ha are professors and students at the same university, Do-hyeon often gives Se-ha a ride when the time is right. Then Siwoon, who was listening, was not outdone and raised his hand and shouted.

“Me too! Then give me a ride too!”

Haha~ Yes, of course.”

In fact, Si-woon has a few hours to spare until today’s first class, but he competitively joins in as if he can’t leave Do-hyeon and Se-ha alone. And both Do-hyeon and Se-ha find Si-un’s appearance cute and accept him without saying anything.

However, after the three are dressed and ready, they are about to get into Do-hyeon’s car, but Si-woon grabs Se-ha’s hand and gets angry again.

“Sister, ride in the back with me.”

“What? But…”

“It’s okay, get in the back, Si-Woon will be bored if he’s alone.”

“Yes.”

Hearing Do-hyeon’s words, Se-ha rides in the back with Si-woon with an expression of helplessness. And just in case, Si-woon clings to Se-ha not long after the car starts.

“Jeok~ Jjoe~ Noona~ Noona~ Whoop~”

“Ha! Eup… Puha! This guy is also dangerous while driving!”

“What do you think? Don’t you always do dirty things when you go with dad?”

“No it’s not? Do-hyeon, you don’t play pranks like this while driving!”

As he said, Do-hyeon is surprisingly strict when it comes to driving. He never does any dirty tricks while driving and never touches Se-ha in the passenger seat at all. But this time, he looks back through the mirror and gives Seha permission.

“Seha, it’s okay, so give it to me. It will take a while to arrive.”

“But…”

Still, when Se-ha hesitates, Si-woon puts on a pouty expression again and speaks in a questioning manner.

“Even at my sister’s school, whenever there is a break between classes, I have sex with my dad in the professor’s office. So, you should do this to me too!”

“Oh my, did you know?”

Seha answers Shiwoon’s words with a harsh tone. And just as Si-Woon said, Se-Ha and Do-Hyeon had sex in the professor’s office or bathroom whenever they were at school, so when Si-Woon came out like this, he was at a loss for words. Well, it seems like she didn’t even notice that other professors liked her when she was having sex at school.
Anyway, Seha seems to have given up and sighs as she pulls up her top and exposes her breasts.

“Whew~ Instead, if my clothes get wrinkled, I won’t just leave it alone?”

“I said I understood, whoop~”

“Wow♡”

Si-woon begins to suck on Se-ha’s exposed nipples with the piercings he had pierced before he can take off Se-ha’s top and bra.

Then Se-ha shakes his head and takes off his clothes, folds them well and puts them aside, while Si-woon eagerly sucks the other nipple and piercing. Next, he kisses Seha while massaging his breasts with his hands.

“Jjung~ Jjung~ Churrup~”

“Haeup♡ Yes… Yes… Oh, you can’t leave a kiss mark on your neck or anywhere visible?”

“Yes~ Yes~ Hurururup~”

“Uuuuu♡”

As they kiss, Siwoon takes off her skirt and panties. However, the stockings that went up to her thighs were left on, and they started having car sex in a somewhat uncomfortable tangle in the backseat of the car.

– Swoosh~ Sigh! Puck! Puck! Jjigeuk~ –

“Huh! Sssss…

As I said, Do-hyeon doesn’t touch Se-ha while driving, so this is Se-ha’s first time having sex in a running car like this. So, whenever other cars or people pass past the window, even though I know they can’t see me, I get goosebumps and my pussy tightens.

And Siun also covers Seha’s mouth with a kiss to prevent her from moaning too loudly, or enjoys the feel of Seha’s tongue while sucking on his finger.
The two people are enjoying sex like that, but they really don’t notice the time passing, so Do-hyeon clears his throat and says.

“Hmm! “It’s getting there now, so finish it.”

“Haha~ Haha~ Already? Ugh… Siwoon, stop cumming in your mouth. “If it cums in the vagina or gets on the body, it’s a hassle to dispose of.”

“Ugh… I hate it! I’ll pack it inside! “I’m going to make you walk around with my cum all day long!”

“Hey! “Listen to me… Haeuuuuu!”

– Boom! Puck! Puck! Puck! Puck! Puck! Puck! Puck! –

However, Si-woon seems to have no intention of listening to Se-ha’s words at all, and instead thrusts his cock even harder and turns his back.
Then, when I finally put my dick in as far as I could and ejaculated inside the vagina, Seha whined with an embarrassed expression.

“Hey~ Shiwoon~ I really think you’re going to go home and get scolded! Mr. Do-hyeon, is there anything you can block in front of you?”

“Yes, here.”

Then, Do-hyeon hands him an egg-shaped vibe as if he had prepared it, and Se-ha pulls out Si-woon’s dick and inserts it like a tampon before the semen flows, blocking the semen and putting on panties. And he speaks while looking at Si-un, who is in a wise man’s time and is looking at Se-ha with a frown on his face.

“You go out first. “I’ll be leaving in a little while.”

“Huh! See you later, sister!”

Just as the car arrives at the school and stops, Si-woon runs away, and Se-ha sighs as he gets dressed and fixes his makeup. But when he finally finished preparing, Do-hyeon pressed a switch without saying a word. Then…

– Weeeee~ –

“Huh!? Do-hyeon… Professor!”

“Hehe~ You don’t know when the vibration will go off, so be nervous, because they won’t even watch you during class.”

“Profit! Siwoon, that guy!”

Se-ha, who suddenly started playing with the vibrator because of Si-woon, glances once again in the direction where Si-woon left.

Then Do-hyeon chuckles at that and continues speaking.

“Haha, come to the professor’s office later when you have class. “I’ll take out the vibe and scrape out all of Shiwoon’s semen with my dick.”

“Yes, so you can’t turn on vibrate during class!”

“You don’t know that.”

“Ugh! After all, father and son are the same! “I’m going!”

With those words, Se-ha got out of the car, but her vagina and womb were filled with semen from her son, Si-woon, and her father, Do-hyeon, blocked it with a vibrator holding the switch.

And as expected, on that day, Do-hyeon rang the vibrator several times during class, and Se-ha barely held back from tasting it, but as soon as class time came, he crawled to Do-hyeon’s professor’s office with his trembling legs with a red face and got fucked to his heart’s content. .
