Chapter 408 – 41. Swapping With Yeonwoo and His Wife – Day 4 +A – (27)

Rather than swapping… It was now just Si-woon and Yeon-woo’s happy cohabitation, but anyway, the seventh day dawned. However, Si-woon and Yeon-woo had been drinking so decadently yesterday that they woke up a little before noon and when they saw each other sober, they became awkward again and there was an awkward atmosphere.

Then, in the end, the one who couldn’t bear the atmosphere and escaped was Yeonwoo, who hit her anal vagina with a glass of alcohol yesterday.

“Hmm! Then, I’ll at least make some coffee, so you can wait here.”

“Yes, okay honey.”

Listening to the sound of honey, which is now quite familiar to Si-woon’s mouth, Yeon-woo leaves the bedroom and heads to the kitchen, where she puts water in the coffee pot and takes something out of the drawer next to her while the water boils.

– Squeak! –

From a small box in a drawer, Yeonwoo takes out a small pink plastic plate with 21 pills listed by date, all of which she has already taken halfway through. And when Yeon-woo opened today’s medicine and was about to drink it with water, someone suddenly grabbed Yeon-woo’s hand from behind and stopped him.

“Oh! Siwoon?”

“…”

Yeon-woo is so shocked that she can’t even call him honey and shouts Si-woon’s name, but Si-woon looks at the birth control pill in Yeon-woo’s hand seriously, as if he has no intention of questioning such a thing right now. In fact, it is polite for a woman to take birth control pills before sex without the man knowing, and it is good manners for the man to pretend not to know about it. The exception would be when a man gives birth control pills using his own semen.

However, even though Si-woon clearly knew that Yeon-woo had used coffee as an excuse to take the pill, he followed her and is now even directly trying to stop her from taking it. Yeon-woo intuitively senses Si-woon’s intention, but he hesitates because he cannot say it out loud, and then Si-woon opens his mouth first.

“You know, can’t you take birth control pills?”

“No, that’s…”

The words that come out of Si-woon’s mouth are exactly as Yeon-woo expected, but even though Yeon-woo is not as surprised as she expected, she cannot accept them, so she blurts out his words. Then Si-woon hugs Yeon-woo and starts whining.

“Just for today, okay? Honey, she said she has a hard time getting pregnant, so just for one day. Huh? Huh? Please~ This is a lifelong favor.”

“Tsk… No matter how cute you ask, this isn’t possible! “Do you really get angry when Si-woon doesn’t listen to your sister?”

Although Yeon-woo didn’t accidentally call Si-woon “Yeo-bo” Last time, this time she intentionally calls Si-woon’s name, emphasizing the fact that she is his older sister. However, even though Yeon-woo stops playing as a couple and shows a straight face, Si-woon, who has already had sex with her several times, senses that Yeon-woo is actually shaken inside and does not stop pestering her.

“Don’t do that~ You take medicine every day anyway, so just because you don’t take it for a day doesn’t mean the medicine loses all its effectiveness. Huh?”

“That’s true, but… Anyway, no! What if I get pregnant just by chance?”

“If you get pregnant, you can make an excuse by saying it was pierced even though you took birth control pills. “It could be that the uterus has been completely soaked in semen for several days like this.”

“Of course, that’s true too… Ha, but no! “What if Hye-rim or Se-ha’s dad finds out?”

“We both decided not to contact each other, but if we keep quiet, how will we be found out? Even if you become pregnant, you won’t know right away. It will be several months later, so you can just ignore it then.”

“Ugh…”

Even though Yeon-woo tries to make excuses here and there, Shi-un continues to refute her, so she is gradually persuaded and changes her mind. Still, at times like this, he shakes his head vigorously to come to his senses and speaks sternly again, as if he, the adult, needs to come to his senses.

“Anyway, if you can’t do it, you can’t! Si-Woon promised your sister that when you graduate from college and become one, Si-Woon will unconditionally give birth to your child… Hah!? Ugh~ Jjung!”

“Jju~ Julup~ Jjong! Wow! Phew~ Honey, will you do me a favor?”

“No, I said it wouldn’t work, so what…?!!?”

“Whoop, whoop, whoop!” Tsk! Tsk! Ugh~ Even if it’s like this?”

“So how many times should I say it… Hmm! Churrup~ Chulup~ Chulup! “Wow!”

When Si-woon tries to say something negative, Si-woon immediately kisses Yeon-woo’s mouth and begins to pester her by repeatedly asking her with a clear answer. Then, every time Yeon-woo’s tongue stirs the inside of his mouth, his brain feels dizzy, and his steadfast willpower is weakened.

‘Tsk… Siwoon, you’ve figured out how to use my body perfectly♡’

Yeonwoo knows that he is weak to this side of Shiwoon, but knowing this does not mean he can resist it. In the end, when Si-woon traps Yeon-woo between the kitchen wall and his own body and continues to gently kiss and tease her for over 10 minutes, Yeon-woo finally surrenders as his tears turn moist, and his face turns red.

“Huh~ Hak~ Hak~ Okay, but it’s just for today?”

“Oh yea! Did it! Side~ Side~ As expected, my honey is the best in the world! “Let’s go~”

“Hey, I don’t know anymore! Side ♡ Chureup~ Side ♡”

When Si-woon finally gets her consent and clings to her and kisses her again, Yeon-woo becomes desperate and throws the pill she was supposed to take today down the sink and turns on the water to drain it. And Si-woon, who confirmed this from the corner of his eye, picks up Yeon-woo’s body with a triumphant smile on his face, carries it to Se-ha’s room, and throws Yeon-woo’s body on the bed in that room. And then he climbs up and pounces on Yeon-woo while taking a sip of his own food.

“Let’s have sex quickly! Mating sex! Mating sex!”

“Ugh… You little beast, you’re in real trouble now.”

“Okay, wet my dick! Whoop~ Tsk~ Tsk~”

“Huh! Ugh… Harup~ Jjuup~ Jjuup~”

Si-woon turns his body over and gets on top of Yeon-woo in a 69 position, and he begins to caress Yeon-woo’s pussy by sucking it. However, Si-woon’s cock is already erect, almost ready to explode from the excitement of finally having sex with Yeon-woo without contraception, without any need to erect it, and Yeon-woo wets his cock with saliva so as not to hurt her pussy.

And as soon as Yeon-woo’s pussy becomes moist, Si-woon turns his body over again and rubs his glans against it, and then plunges his cock into Yeon-woo’s pussy, which is defenseless like a baby due to not taking birth control pills.

– Puchuk! Kkukkkk! –

“Ugh! Ah… Black… Huh♡”

“Huh!? Wait, wow… What the fuck?”

Si-Woon fucked him the same way as usual, but with the only difference that he didn’t use contraception, a thrill that was incomparable to before sent a tingling sensation from his testicles, down his spine, and all the way to his brain. And perhaps it’s the same for Yeonwoo, unable to overcome the overwhelming emotion and excitement, twisting her body this way and that and tightening her pussy. Siwoon dives into Yeonwoo’s arms and begins to copulate in earnest, shaking his hips back and forth like a dog in heat.

– Squeak, squeak, squeak! Sigh! Tsutup~ Tsutup~ –

“Huh!? Sssss-b-baby, just a moment… Just a moment, slowly… I love it so much I feel like my brain is melting, so just fuck me a little slower!”

“Sigh~ Sigh~ I’m sorry honey, I feel like I’m going to cum right away if this continues, so I want to take it slow, but my back just won’t stop! Damn, honey’s pussy feels so good!”

“So… Huh!? Sigh! Haaaaang♡”

In fact, as Si-Woon said earlier, the chances of Yeon-Woo becoming pregnant just because she didn’t take the pill today are very low. This is because Yeonwoo has been suppressing ovulation by taking birth control pills for over ten days, and in other words, there are no eggs in Yeonwoo’s uterus right now. And since the hormones from yesterday still remain in Yeonwoo’s body, this state will usually continue for the next few days, so in fact, if she does not take the contraceptive pill today, it will be a few days before she becomes pregnant.

This is the same principle as when women actually take birth control pills, they usually take a set of 21 pills, one pill a day for 3 weeks, then take a break for a week and then start the cycle again, but the contraceptive effect is maintained even during that break.

So in Yeonwoo’s case, if she takes the contraceptive pill again tomorrow, the risk may go away, and in the first place, Yeonwoo has a constitution that makes it quite difficult to get pregnant, so even though she has been working hard in meetings for 20 years, she has still only had two children.

For this reason, both Yeon-woo and Si-un theoretically know that the actual risk of pregnancy is low, but the symbolism of having sex while she has stopped using contraception has turned them into beasts.
And Si-woon didn’t stop from the first insertion until the climax, shaking his waist like a dog, thanks to which he reached ejaculation in about 5 minutes, the fastest time in recent times.

“Honey, let me cum! “I’m going to cum in your unprotected pussy!”

“Tsk… Cum! “It’s already happened like this, so I cum until my uterus is full!”

“Kuhuhuh!!!”

– Pewfew! Phew,~ Phew~ Puchuk! Puchuk! Slurp~ Slurp~ –

“Huh!? Tsk… Sigh! Awesome! Haaaaa!”

Although the sex was intense, it was quite short, but Yeonwoo was much more sensitive than usual, so luckily she was able to reach climax with Siun. However, Si-woon’s sexual desire is still incomplete, and even after ejaculating all the semen, he continues to turn his back and cries out persistently.

“Pfft… I’m pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! Get pregnant! “I’m pregnant!”

– Squeak! Squeak! Squeak! Squeak! Squeak! Squeak! Squeak! Squeak! –

“Huh~ The semen was whipped inside me… Huh!? Haaaaang♡”

Thanks to this, Yeon-woo’s uterus and the inside of her vagina become a complete mess with Si-un’s semen, and Yeon-woo also clenches her teeth and convulses as if sobbing. After a stormy climax, the two overlap their bodies and catch their breath, but Yeon-woo feels something out of place and is startled.

“Huh? Why… Isn’t it shrinking even though I just wrapped it?”

“Right? Honey, I feel strange. “Even after ejaculating, my erection doesn’t go out, what should I do?”

“Ugh~ What the hell, what the hell, it’s already been like this so come face to face with the intention of making me pregnant!”

Yeon-woo, already feeling that her unprotected womb is filled with Shi-woon’s semen and gurgling, hugs Si-woon with her arms and legs with a refreshing expression, encouraging her like that, as if she has decided not to run away anymore and to accept this situation head-on.

Then Si-woon smiles brightly and nods his head loudly.

“Huh! “I will definitely use this opportunity to get my wife pregnant!”

“…”

Seeing Si-Woon’s enthusiastic appearance, Yeon-Woo keeps quiet, worried that she might actually become pregnant. The explanation above that the possibility is low is clearly an objective fact, but it is true that the probability of pregnancy has increased, even if only slightly.

However, Yeonwoo’s anxiety was sublimated into a thrill, and even during the sex that followed, an even more exhilarating pleasure than usual overtook Yeonwoo’s body, and in the end, Yeonwoo was unable to put the brakes on Shiwoon and ran wild with them.

Anyway, on the seventh day that Si-woon tasted Yeon-woo’s raw vagina, he finally succeeded in truly having sex with Yeon-woo without using any contraception. On that day, the two of them copulated, cumming all day long without any special play. It was repeated infinitely.
