Chapter 742: The Couple’s Heat Cycle (1) (Illustration Warning: Mature Content)

Around the time Sung Taekyung was making Han Seon-ah perform fellatio in the room.

Her twin older sister, Han Jin-ah, was also watching the scene silently from beginning to end.

‘F-fellatio, is it normally done to that extent?! A-and besides, while masturbating….’

Unlike Han Seon-ah, who was naturally curious and secretly quite knowledgeable about lewd things, and Han Min-ah, whose development in that area had progressed a bit quickly while hanging out with Sung Taekyung.

Han Jin-ah was the least knowledgeable about sexual matters among the three sisters.

In other words, she could be called the most innocent of the three.

While thinking the situation, which was undeniably lewd to any ordinary person, was strange, she was instead jumping to the conclusion that perhaps this was normal.

‘I-it looks like she feels good though…. Still, doing it to that extent is a bit….’

How about masturbating while kissing Taekyung Oppa, instead of fellatio?

Ah, that might definitely be okay.

Kissing with Oppa feels good and makes my heart comfortable. Masturbating while doing that would undoubtedly feel good.

‘No no no no…! W-what kind of thoughts am I having!’

Showing myself masturbating in front of Oppa was not something a sane person would do.

In the first place, I couldn’t know if Taekyung Oppa would even accept my request to masturbate while kissing.

And, actually, if something were to enter down there anyway, Taekyung Oppa’s fingers would preferably feel better than my own….

“…Nngh, Hngh.”

Han Jin-ah had thought of such fantasies while watching the lewd acts between Han Seon-ah and Taekyung Oppa.

Before she knew it, her fingers had naturally moved towards her lower body.

Even though she didn’t usually show signs of accumulating sexual desire, Han Jin-ah was also an Animal-type Hunter, just like her other sisters.

She possessed a constitution that couldn’t help but feel the backlash of her long-suppressed heat period, just like her other sisters.

‘Anyway, that Han Seon-ah should have told me Oppa arrived…. Saying I was sleeping and keeping it secret just for herself, how selfish….’

Even so, Han Jin-ah had sometimes harbored the desire to monopolize Taekyung Oppa’s affection, so disturbing their time together felt wrong for some reason.

Aside from the strangely reassuring feeling when Seon-ah or Min-ah Unnie were nearby while being embraced by Taekyung Oppa, there were times she wanted to receive that great affection all to herself.

Of course, if Han Jin-ah herself were to get greedy trying to handle that affection alone, it was obvious she’d collapse in less than an hour, so she simply didn’t express it.

Therefore, she always felt grateful towards Han Seon-ah, who shared the burden of Taekyung Oppa’s sexual desire that was difficult for her to handle alone, but…

Seeing her younger sister Han Seon-ah in that state, she inevitably couldn’t help but think that perhaps she wasn’t the only one receiving help.

‘Just a little longer…. Let’s go in after waiting a bit longer….’

Until Seon-ah sufficiently relieved her heat period’s desire, and additionally relieved some of Oppa’s desire too.

While thinking that, her hand, as she quietly watched the scene of the two people, was naturally rubbing between her own groin.

It was Han Jin-ah, who had unintentionally started voyeuristically masturbating by chance.

Unaware that Taekyung Oppa had already noticed her arrival at the door.

“Gguheuueup…! Ku, Hueuueup…!”

Han Seon-ah, having swallowed my thing completely into her throat, reached climax right then.

The sight of her spurting the climax fountain from below, despite clearly having shoved it into her mouth, was incredible in many ways.

The only person who had shown reaching climax while displaying such a lewd appearance up to this point was, at most, someone like Sihee.

Seeing that Min-ah or Jin-ah aren’t like this to this extent, it seemed perversion didn’t necessarily have a particular connection to genes.

-Tseueup….

“Keuhup, kyak…. Ge, keuhup, ket….”

“Are you okay, Seon-ah?”

“Yes, yehet…. O, Orabeo, ni….”

Han Seon-ah answered, tears showing in her eyes from having my penis suddenly thrust deep into her throat.

Her state was extreme enough that it couldn’t simply be described as shedding tears, whether from her eyes or elsewhere.

“So, how is it? The feeling of being raped by the Oraboni in your fantasy?”

“It, it wasn’t a fantasy after all…. Somehow, I was starting to feel something was a bit strange from the middle…”

“From when?”

“Around the time Oppa’s fingers entered my lower area, I did think it was a bit strange…”

…She noticed much later than I thought?

“When my chest was being touched? Did you really not know?”

“Th-that much is a common fantasy I usually have…. Like, imagining Oppa while touching myself…”

“Usually often?”

“Ah, no…! I-I just misspoke.”

Han Seon-ah accidentally said the fact that she usually masturbates while thinking of me, then quickly corrected herself.

It seemed to take her quite some time to realize that the sensation of me touching her wasn’t a fantasy because of that.

Of course, even if she corrected herself now, it wasn’t particularly convincing, but I let that part slide instead of pressing the issue.

“A-and also….”

“Mm-hmm.”

“It, it wasn’t exactly rape… Since it was Oppa…”

“……”

“T-to Taekyung Oppa, whatever happens is okay. So even if you ask how it feels to be raped, I, I can only say I felt good…”

Seon-ah’s appearance, speaking with a shy face and smiling sweetly, felt exceptionally lovely.

…But in reality, she avoided my gaze with a guilty face not long after uttering the words.

“It, it might be a little late but….”

“Huh?”

“T-today’s matter, I’m sorry, Oraboni….”

“Huh? …Ah, you mean you were masturbating in my room until just now?”

“……”

“Well, this kind of reaction would normally be considered normal. It’s not specifically a male-female issue, but if someone secretly entered another person’s room and got caught masturbating. In this world, a woman being caught by a man was something she couldn’t help but feel more guilt over than a man being caught by a woman. Especially since it seemed she had stayed in my room for quite a long time even before I arrived; besides the pen dropped on the floor, other traces of masturbation remained for a long time. In fact, it would be correct to assume she had spent quite a long time alone in my room relieving her sexual desire.

“Why were you doing that?”

“……”

“If you don’t tell me honestly, Oppa might not forgive you.”

“…I-I wanted… to masturbate…”

“……”

“I-I originally intended to do it in the bathroom… B-but when I tried to go in, Eunbyul Unnie said the bathroom was being cleaned, so she told me to go to the master bedroom… But Jin-ah Unnie was in the master bedroom, so I’d get caught, so I wandered around…”

“And then you came into my room?”

“O-Oppa said you were coming the day after tomorrow… S-so I’m sorry, Oraboni….”

As soon as I mentioned I might not forgive her if she didn’t speak honestly, Han Seon-ah revealed her own flaws one by one.

And then, perhaps remembering what she had done anew, she shed tears and looked like she was begging for forgiveness.

Based solely on the sexual desire fetish I checked previously, I had thought it was just simple masturbation addiction, but it seemed Seon-ah inevitably had much stronger sexual desire than I had thought back then.

Usually, even when trying to masturbate, the mood tends to cool down if one fails once or twice, but seeing that she persistently entered my room to do it anyway… you see.

“Yes, yes. Thank you for telling me honestly, Seon-ah. You did well.”

“…W-will you not punish me?”

“Why would I punish our good Seon-ah? If you told me these embarrassing words honestly, that’s enough.”

“B-but still… I did this thing in Oppa’s room as I pleased….”

“If having strong sexual desire were a crime, I’d already be serving a life sentence. Coming up to Oppa’s room while looking for a place to masturbate was wrong, but since you told me honestly like this, I’ll forgive you this time.”

“Yes, Th-thank you, Oraboni!”

As I stroked the ears and hair of Seon-ah who spoke honestly, she expressed her feelings with her wagging tail.

In the original world, I would have felt more apologetic, being the one who peeped at her masturbating.

Moreover, the very act of her coming all the way to my room and masturbating, unable to resist momentary sexual desire, was in a sense my fault.

Regardless, it meant I had caused Seon-ah’s sexual desire to build up, making her unable to control her desire like this.

Spinning the chair she was sitting on around to make her body face me, I thrust my penis, which had become hard again after one ejaculation, forward in front of Han Seon-ah’s eyes.

“Then, I’ll have to resolve our Seon-ah’s built-up desire, which she can barely stand, right away.”

“I-is it okay though? I, I already did it once, so this time it should be Jin-ah Unnie’s turn…”

“It’s fine. I’ll relieve Jin-ah sufficiently later. And besides, the one who can’t stand it now isn’t your sister, it’s you, Han Seon-ah, right?”

“That is true, but…”

“I’ll take care of relieving your heat periods myself, so for now, just obediently do as I say.”

“…Yes, Oraboni.”

Anyway, since she herself had committed a transgression, Seon-ah obediently entrusted her body as I commanded.

After pulling her body closer towards me on the chair, I immediately thrust my penis into Seon-ah’s already slick and wet vagina.

-Jjilggeok!

“Eut, Hureuueung…!!”

Seon-ah’s vagina, having reached climax once, tightened around my thing a little strongly.

Her body reacted sensitively, slightly surprised by my thing entering after almost several months.

I immediately thrust my penis forcefully into her body like that, and her sensitive body swallowed it whole, as much as possible.

-Jjilggeeok!!

“Heuut, Haaaaang!!”

Han Seon-ah accepted my thing with her slick vagina, which had been slick for a long time.

First, I must properly relieve her sexual desire right in front of me.

…And after that, it will be Han Jin-ah’s turn, who is waiting outside the door right now.
