Chapter 163 – 25. Should Prostate Massage Be Regarded as Piercing the Young Man’s Membrane (3)

Seha finally brought out Bixxra as a reward for Siun graduating from youth school. And as expected, the effect was so great that Si-woon regained his erection even before the effects of the medicine reached his cock and began rubbing his glans against the entrance to Se-ha’s vagina.

“Ah, her pussy is really plump, so sucking it from the inside is fucking delicious. It’s already been three days and I don’t think I’ll ever get sick of it.”

Surely it’s already the third day and the last day of the holiday, but the more Siun tastes Seha’s pussy with the mucous membrane of his dick instead of his tongue, the a more new taste comes out, and it seems like he won’t be able to stop it.

Moreover, since he still has Aneros stuck in his anus, he continues to be stimulated by his prostate, and with a new feeling, he pushes his erect dick into Seha’s pussy.

– Grumble~ Grumble! Awesome! –

“Wow! Is this the power of BXX?”

“You crazy guy! “There’s still a long way to go before the medicine takes effect… Ugh!”

Se-ha is once again licking his tongue at the young men’s endless monkey-like energy, but somehow he gets aroused and turns the Aneros stuck in Si-un’s anus on vibrate with his cell phone.

“Eight, die!”

– Weeeee~ –

“Huh!? This is real! “Try the same thing!”

“Uh? Haha!”

Si-woon grabs the anal vibe from next to him and inserts it into Se-ha’s anus. Se-ha grits his teeth and moans loudly as he gets penetrated in both holes.

In addition, Si-woon turned on the vibration on the vibrator inserted into Se-ha’s anus and rammed his dick into her vagina at the same time. In the end, Si-woon and Se-ha ended up having sex with the vibrator inserted into their anus.

– Weeeeeing~ Weeeeeing~ –

“Ah! Hey! Isn’t the vibration on your side too strong? How can it shake from the prostate to my pussy!”

“You’re funny, is this the vibration from your sister’s side? And you were the one who turned on my vibration in the first place! Hehe!”

Si-woon, who shouts like that, also grits his teeth and lets out a harsh breath as the violent vibrations come straight from Se-ha’s rectum to his cock.

From then on, they hold the switch of the vibrator in each other’s anus and increase the intensity of the vibration when the other person is weak, competing as if martial arts masters were fighting. In fact, the two people do not simply vibrate strongly, but they repeatedly attack by stabbing with their dicks and squeezing with their pussies to create an opening for the other person.

Although tension was maintained in the beginning, Seha, who had more experience with anal vibration, was much more durable in the first place. And since he had experience attacking men’s prostates, he took advantage of this and adjusted the vibration exquisitely, and in the end, Shiwoon couldn’t hold out any longer.

“Ugh~ Sister Seha, I think I’m going to cum again!”

“Yes, cum as much as you want.”

“Are you okay? Is it okay for me to cum as much as I want in my sister’s pussy, vagina, and womb, as well as the baby made from my balls?”

“Ugh… ♡ What’s new, sssss… I’m cumming with a force that will pierce the effect of the birth control pill!”

“Sigh~ Sigh~ Sigh… Sigh~”

“Eup… Yes… Yes… Eup~”

Si-Woon’s feelings of affection seem to have exploded because he is being intense, so he puts his head down on Se-Ha’s chest and whines, and Se-Ha hugs Si-Woon tightly, squeezing Si-Woon’s body with both her legs and her pussy.〈 Br〉
And while this was going on, the vibrators were digging into the two people’s anuses and vibrating vigorously. Eventually, Si-woon, using the power of the vibration, convulsed violently as if pumping semen from his testicles, gritting his teeth, moaning, and starting to ejaculate.

“It really cums! “Wow!”

– Weeeeea Wow! Damn! Pucheuk~ Pucheuk~ –

“Ugh… Haaaaa! Wait a minute … It’s so big that it vibrates in a semen, so it’s a big thing in the vagina …

Se-ha tries to stop Si-woon because he feels something different from usual, but Si-woon himself cannot stop on his own when he is in the middle of ejaculation. And when Seha’s pussy and Shiwoon’s dick vibrated on both sides and stirred up the semen ejaculated in the vagina, the semen bubbled up and began to leak out of Seha’s vagina in white color, as if it had been put into a whipping machine.

In addition, changes that are different from usual also occur within Si-un’s body.

– Sussssseu~ hot! Hot! –

“Huh?! Is your erection not going away even after ejaculating? Ah, that’s right!”

“Do you think the medicine is really starting to take effect now? Ugh~♡”

As they say, BXXRA is now truly effective, and the erection is maintained even after Siun is gone. So, Si-woon continues to piston and thrust his cock against his will, as if he had a motor in his waist due to the sensation he was experiencing for the first time in his life.

“Aaaaahhh! It won’t stop!”

– Crunch~ Crunch~ Crunch~ Crunch~ Crunch~ Crunch~ Crunch~ Crunch~ –

“Huh! Ugh~ Tsk… Damn, let’s see how this ends! I want you to use everything you’ve learned so far and use your body to your fullest to excrete all your sexual desires! Ugh!!!”

“Good! It was clearly said through my sister’s mouth!”

As soon as Si-woon catches Se-ha’s words, he rushes in, takes another egg-shaped vibrator from the side, turns it on, and presses it against Se-ha’s clitoris.

-Jiiiiing~ –

“Aha! Tsk… Hey!!! Anyway, that’s foul… Phew!”

“Damn, my fingers are falling off!”

Just by holding the vibrator with his fingers, Shiwoon’s knuckles go numb and feel like they might fall off, but just imagining what kind of state Seha is in as she receives it with her clitoris makes him feel sad.

However, thanks to BXX, Si-woon is unable to control his sexual desire as he continues to thrust his erect cock into her vagina, and Se-ha also trembles and squirts out urine as her clitoris and urethra are pressed together by the vibrator.

– Wow~ –

“Aaaaah! Ugh… Even the urethra was loosened! Tsk… Sigh! Ugh! “Huh~”

“Wow! So what! CX This is really crazy, hehe! “Huh, huh, huh!”

Si-woon hugged Se-ha’s body tightly even though urine was gushing out, and the sofa collapsed, shaking his lower body and entire body like a caterpillar and chewing on him. It pours bodily fluids through the hole.

And both Seha and Shiwoon have already passed the part where they can control their bodies with reason. The two people, whose boundaries between humans and beasts had literally collapsed, continued to have sex as non-XX members for several hours.

.

.

After that, Se-ha and Si-woon continued to have sex,

Have sex while eating something,

Having sex while drinking water,

Then, for a simple bathroom, I solved it by just covering myself on the sofa,

Having sex using tools,

Have sex with your bare body,

Having sex while washing,

Then, I fell asleep for a moment with my genitals connected,

Wake up and have sex again,

Then we had sex while eating something,

Having sex while drinking water,

And then we sit on the restroom and have sex while working,

Anyway, as we continued to have sex like that, the last day of the holiday was quickly coming to an end.

So now it’s time to sort things out and contact Do-hyeon, but Se-ha and Si-woon are completely absorbed in indulging each other’s bodies and can’t pay attention to anything else. And Do-hyun hasn’t even contacted me to see if he was roughly anticipating this situation.

So, in this atmosphere, all of tomorrow’s lectures are canceled and extended for another day, but Seha and Siun can’t even pay attention to that and are only focusing their attention on their dicks and pussies, and the mucous membrane of each other’s lips and tongues that are connected by kissing. .

Then, it was a phone call from Shiwoon that forcibly brought the two people’s consciousness back to reality.

– Beep~♪ Beep~♫ –

“Huh!? Who is it?”

“Who is this? No, rather, what time is it now? Is it already night?”

“Wait a minute, sister, where… Did you get a call from Eunhyuk?”

When Si-woon checks his friend’s name on his phone, he gets an ominous feeling that he has forgotten something. However, he has not completely regained his senses and just makes the call feeling vaguely anxious.

“Hello, Eunhyuk?”

“Oh~ Siwoon. What are you doing that you don’t talk about at all during the holidays? “I contacted you to see if he died, and you did your part in the group assignment, right?”

“Oh right. Group assignment. There was something like that.”

“What? “You bastard, what is that…”

“What!? Hehe~ Nu, older sister! I’m on the phone right now… Wow!”

As Si-woon is talking on the phone with his dick in her vagina, Se-ha makes a pouting expression and tightens her vagina while flexing her waist and squeezing his dick. Then, Si-woon, whose glans had become more sensitive after having sex all day long, let out a heavy breath, and as soon as he had regained his senses, he flew out again and shouted urgently as if putting out a fire.

“Tsk! I’m sorry Eunhyuk, I’m out of my mind right now… Ugh! Pfft!”

“Hey, you, what’s wrong with you? Where does it hurt? Are you okay?”

“Sorry! “I’ll do it just one more day, just one more day… Just one more day!!!”

“… Heo-eok, are you really in the process of taking off your baby right now?”

Only then did Eunhyuk realize the situation and ask out loud in surprise. Then, Si-woon slowly thrusts his cock into Se-ha’s pussy and barely manages to come to his senses and respond.

“Yes, Ada already died three days ago and has been going on ever since.”

“Gulp~ The other person is Seha’s sister?”

“Yes~♪ Hello, Eunhyuk~ I’m sorry~ Haeuuuuu!”

“Huh! Oh, no. Sister.”

When Seha shouted loudly and answered for him, Eunhyuk was so overwhelmed by the situation that he could no longer argue.

However, after hearing that he and Se-ha have been having sex for several days, he feels envious and jealous, and immediately criticizes Si-woon.

“Hey, you envious bitch… Hmmm! No, I’m still in the process of weaning off my virginity, so please be extra generous and understanding. And I’ll explain to the other group members that it’s because I’m trying to get rid of you, so shoot me later.”

“Yes, thank you. “I’m distracted right now because of Seha’s sister’s tightness.”

“Wow! As expected, just hitting on one side won’t do. You’ll have to explain to me in detail about having sex with Se-ha noona later, so take care of it. “So you’ve skipped all classes tomorrow?”

“Okay, so I’ll see you the day after tomorrow. “Maybe.”

“Okay, then hang up. Aw,~ I’m really jealous of this bastard.”

Eunhyuk hung up the phone, congratulating his friend on getting rid of Ada, and thanks to this, the group assignment would be resolved somehow.
And thanks to Eunhyuk, Siwoon started thinking about Dohyeon as well.

“Haa~ Haa~ I guess I should call my sister and dad too, right?”

“I sent a message to you while you were on the phone. Come tomorrow evening or the day after tomorrow morning.”

“Oh, good job.”

Se-ha quickly finished contacting Do-hyeon while Si-un was on the phone with Do-hyeon, and although Se-ha and Si-woon didn’t say anything, she took it for granted that the extension until tomorrow.
And with this, when all external matters were taken care of, the two people smiled brightly as they focused on each other again. After that, the two continued to have sex for hours, and it wasn’t until dawn that they finally collapsed.
