An affair with my stepsister…! (2)

The illicit affair had begun.

It might seem strange to call sexual relations between a man and a woman an illicit affair, but for him, there was already a sister with whom he had clearly drawn a line among his sisters.

They were tickling each other, laughing, and smiling, each exploring the other’s body as man and woman.

For her, it was a long-awaited release of sexual desire, with her brother exploring her body.

For him, it was exploring the body of his sister, whom he had only met two days ago, and they both laughed.

Of course, for Ji-hye, this scene was not enjoyable at all.

If she had seen it, she would have grabbed everything in her hands and thrown it, she was so angry, but it was lunchtime now.

It hadn’t even been an hour since Seon-ho and Ju-a had embraced each other and talked naked.

Sharing saliva with their tongues, they confirmed their feelings of affection for each other and gradually prepared to mingle their bodies, which were becoming wet with excitement and sweat.

If they got caught, they might die.

But they wouldn’t get caught.

–

“Uhm, Oppa, just a moment!”

“What is it now?”

As he slowly inserted his dick into her pussy, Ju-a stopped him.

Was she worried because it would hurt since it was her first time?

Or was she just scared? If not, was there any reason to worry?

‘Ah, she probably wants a condom.’

Unlike the other sisters, who all seemed to have agreed to no condoms, Ju-a was different.

Rather, between a man and a woman, the existence of a condom is important and precious.

I don’t have any diseases or STDs, but if I cum inside, I can’t rule out the possibility of pregnancy.

The other sisters seem to be somewhat aware of that, though.

…I should ask them about it later; I really have been shooting blanks without a plan.

She rolled her eyes around, avoiding my gaze, and muttered quietly.

“Um… I heard it hurts if you don’t wet your dick first… Would it be okay…? I heard it’s really dry and hurts…”

I chuckled at her words.

There are things you can put on your dick, but basically, sex is about moving smoothly inside a wet pussy.

You only put something on your dick for people who don’t get wet easily.

“Well, there’s nothing I can do about it, should I go wet my dick with water?”

“I think that would be too cold.”

“Then are you going to suck it?”

“…I’m a little uncomfortable with that since it’s my first time.”

“The only thing left is for me to get you wetter.”

Chureup─

We naturally shared a kiss.

We looked at each other and smiled slightly, and I moved my waist again.

“Ah, what if it hurts?”

“…What can I do? Are you going to hit me or something?”

“That doesn’t mean it won’t hurt.”

“It’s surprising that you’re so worried when you were so indifferent even when we were kissing openly on the broadcast yesterday.”

“Are kissing and sex the same thing or what…”

“Does that mean it feels good if you do it with someone you love and have feelings for?”

Instead of answering my question, she stuck out her tongue and teased me with a “Beh-.”

She didn’t deny it, and seeing her wrap her arms around my neck, I guess it wasn’t the wrong answer?

Only then did I slowly move my waist and insert my dick into Ju-a’s pussy.

“Gently! Do it gently! I might really hit you if it hurts!”

“It’s not like I can make it not hurt by doing it gently…”

“I don’t know, if it hurts because you don’t do it gently, I’m going to get angry after we’re done!”

“I can just not finish so you can’t get angry.”

“Heot!”

She covered her mouth in surprise, but it was already too late.

I could feel her moist pussy at the tip of my dick.

The sticky and warm sensation, and the feeling of countless wrinkles intertwining with my dick.

The pleasure that stickily soaks my brain makes me thrust my waist in immediately.

“…!”

“Ah, does it hurt?”

As I pushed my waist in, she frowned and squeezed tears from the corners of her eyes.

Was it so painful that she bared her teeth and clenched them?

In response to my question, she pulled on the arms wrapped around my neck and clung to my body.

“It…it hurts…this…this…”

“This?”

“…I, if Oppa moves now, I think I’m going to moan─Aang♡”

Before she could finish her sentence, I piston-stroked my waist.

A sweet moan flowed from my ear, and taking that as a signal, I continued to shake my waist.

“I, it’s my first…time…Ah…Aang♡”

“Does that mean it hurts, or does that mean it feels good?”

As I shook my waist, my breath gradually became rough.

Ah, seriously, I’ve recently started to feel the importance of exercise.

I didn’t have much sex before, so I didn’t care, but these days, my body gets tired even if I shake it a little.

Is this what they mean by losing stamina? Actually, if I cum after sex now, I felt like fatigue would hit me hard.

‘If it doesn’t work out, I’ll have to take a pill, there’s no other way.’

“D-Don’t ask a girl something like that…Ma…Aang…♡”

“I need to hear it so I can move my waist more.”

Ju-a was straddling me in the missionary position, her legs spread in front of me, getting pounded by my dick.

Each time I shook, the sticky pussy juices wet my dick, and when I looked down slightly, there were red marks left on my dick.

Virgin blood, every time I see it, I wonder if it’s hygienically okay, but I’m not one to talk since I’m doing it without a condom…right.

Ssuk-ssuk-ssuk─

As I moved my waist at a normal speed, the sound of my dick pounding her pussy gradually began to be heard as much as Ju-a’s and my breathing.

“O, Oppa, there…♡ J-Just come in about…♡ half way…”

“Half? About this much?”

“T-There, it feels good…♡♡ Rub it there…”

I thought she would be too embarrassed to say it properly, but she asked for it clearly from the start.

It’s better this way; if she doesn’t ask for anything, I’ll mistakenly think she likes everything I do.

Even though I’ve had sex with four people, there’s still something to learn.

I should try this with the other girls too, ask them if there’s anything they want.

I feel like I’ve always been unilaterally pounding them.

After shaking my waist, I started rubbing at the end of her request.

I touched her pussy wrinkles as if drawing a picture with my dick.

“Aah─♡ T-There…♡ J-Just a little harder…♡”

Instead of answering, I shook my waist.

There’s a saying that actions speak louder than words.

As I supported my body with my arms and continued to shake my waist, evidence of pleasure continued to flow from her closed mouth.

“Aah─♡ Haat─♡ B-But I, I think I’m going to cum alread…♡”

“Already? Hey, wait a minute, if you squeeze that much…!”

I was just starting to pick up speed, but Ju-a was already hugging my body.

Wrapping her calves around my waist, she clung to my body like a child and trembled.

‘Ugh…I almost came too.’

The legs wrapping around my waist, the squeezing of her pussy.

Clenching my teeth and holding on was just the limit.

The sensation of the wrinkles clinging to the pillar that was my dick was both good and, frankly, quite a pressure.

“Hoo-“

I blew a sigh of relief on my forehead and hugged Ju-a, who was clinging to me.

“Haa…haa…ha…a…”

“Anyone would think we did it a few times…I almost came too.”

“M…My brain feels like it’s melting.”

“…Did you do drugs?”

“Don’t you know that sex is a drug?”

I don’t know, was there such a saying?

I don’t know who said it, but it’s a really appropriate saying.

Because both are really hard to quit once you start.

Clinging to me, she was still breathing heavily, as if it was quite a shock.

Even if it’s your first time having sex, do you cum this quickly?

‘I’m embarrassed because it’s the first time she’s come this quickly.’

I think it’s only been about 5 minutes.

I was a little embarrassed because she already came.

It’s awkward to move in a sensitive state right after coming, and I could feel the sensation of water flowing from my dick that was still inside her.

Is the tide of climax flowing now?

One way or another, since there are five sisters, each with a different flavor, it’s hard to adapt to each one.

It’s a luxurious complaint, but it’s really hard.

“I…I want to do it more…”

“You want to do it more?”

“…If I do it more now, I don’t think I’ll be able to stop, so I can’t ask you to do it…”

“You worry too much, I can just do it more for you?”

“Ah, no, I’ll endure it. I’m sorry, Oppa…”

…She’s really different?

Everyone else usually sees the end and rests because they’re tired, but Ju-a is different.

She cut it off as if a man and woman were drawing a line.

Even though there was still sweetness left in her voice, I could definitely feel that it wouldn’t be good to do it anymore.

‘More than anything, I don’t know what will happen if Ji-hye finds out…’

Is this what the heart of a cheating husband is like?

Actually, if I get caught, it’s natural that Ji-hye would try to kill me.

I wasn’t satisfied, but for safety, at Ju-a’s words, I took out my dick, which was soaked in her pussy.

Bloodstains and white, sticky discharge.

Fortunately, it didn’t get on the blanket much, but in the end, I had to wash it before Ji-hye came.

As the atmosphere suddenly cooled, my dick instantly went limp, and only Ju-a, who was wet with tears and sweat, was on the bed.

The expression on her face as she caught her breath and looked at me changed back to playful, and she clung to my back as I sat there.

“What am I going to do, enjoying it all by myself?”

“The mood’s already ruined, so it doesn’t matter.”

“Really?”

“Yeah, I don’t really think about it much now, but I don’t know about tonight.”

“I heard that guys feel terrible when they stop masturbating halfway through?”

Did she graduate from engineering?

She knows a lot about men, huh?

If she says that, there’s nothing I can say, but it’s a little different for each person.

“That’s true, but there was also the condom issue…Originally, I was going to cum, but it’s enough if you were satisfied.”

Ttok-

I felt the sensation of lips on the back of my neck.

“Why does the Oppa I’ve seen for the first time in 20 years only say pretty things?”

“What pretty things…”

“It is pretty, how many men in the world would say that when they’re not satisfied themselves?”

It’s the result of learning in advance from my sisters, but it feels a little strange to be praised like this.

Using what I learned from my sisters on my sister?

Wow, even an animal would run away and slap its knee and laugh.

She clung to my back, mashing her breasts, and smiled, sticking her face over my shoulder.

When I look at her like this, she’s just a normal girl.

A 20-year-old girl who has just shed her student image and become an adult.

…I messed with someone like that? She’s the same age as Hyun-ji?

Ah, shit, I’m the animal, why am I calling other men animals?

“Ugh…well, you should wash up and get dressed. I’m going to wash the blanket first.”

“Blanket? Why the blanket?”

“I have to wash it so it doesn’t get caught because there’s a virgin blood stain and a water stain.”

“Ah…so Oppa took my virginity?”

“Kellok!”

As soon as I coughed, she lay down on the bed and covered her body with the blanket.

Smiling shyly and sticking out her tongue slightly, she’s a fox.

A child who seems to have mixed the purity and wickedness of a child.

And I, who fell for that, am an animal.

“Can’t we just say we did it with consent?”

“You did take the virginity of a girl who just took off her school uniform.”

“That makes it sound like a criminal attacked her.”

“Hmm…you’re right, you’re the criminal who stole my virginity.”

Ttaak-

“Aya!”

“If you want to get hit with another flick, say more.”

When I flicked her forehead and got up, she smiled and quietly handed me the blanket.

If she asks why I washed the blanket, I’ll just say it smelled like sweat.

“Go wash the blanket. I’ll order food.”

“Alright.”

As I came out to the living room with the blanket, only then did sexual desire slowly rush in.

The desire to pull out one shot with the belatedly rushing sexual desire rose, but I endured it.

I thought to my dick, which was still numb because it wasn’t horny, to find peace.

‘You want to use your strength on a woman you had an affair with, and release your sexual desire on your wife, you animal.’

I said it to blame myself, but it was so appropriate that I have nothing to say.

But I’m an animal.

If Ji-hye allows it at night…I don’t know, should I try asking her kindly like Ju-a?
