With Seoha
"Hiek!? Nngh! H-how much looonger! Hah...! Do I have to keeep goiiing!"
I was kissing Seoha on the yoga mat, our hands wrapped around each other, when Seoyeon raised her voice beside us. Moans clung to every other word and trailed off the ends of her sentences — she was masturbating, rocking her hips, her nipples standing out in hard peaks through her top while her tennis skirt swayed wildly.
Today the two of them had dressed alike: tight white short-sleeved tees and lavender tennis skirts.
"F-forgive...! Hiek!? Forgive meee! Pleas, pleeease! Hghhk!?"
How badly must she have been suffering, to forget even the polite little ending she'd been clinging to at the end of every sentence?
"I told you. Until I cum once."
"I-I knooow! Hiek! Hnnh!? P-please forgive meee... nnh!?"
Seoyeon knelt on the mat, pinching her nipples with one hand and stirring inside herself with the other. When it came to conception duty, a man's word was absolute — no matter how many times she came, she would not stop. The mat had already overflowed. Love juices had spilled past what she could hold and gathered in a puddle beneath her.
"If it's that hard, you should say something to Seoha. The way you're just gently stroking with your hands, I won't even be able to get there."
"S-Seoha...! Pleaseee! Hghhk!? P-pleeease... hngh! Please let him cuuum...!"
Seoha glanced at her older sister, the corner of her mouth curling up.
"Alright! I'll get him off real quick!"
She took her hand off my cock and stepped back. That face full of mischief looked like she was about to pull something.
"But from now on, you work your clit."
"T-that's!? You knowww! Hngh! Unnie's c-clit is too sensitiive!?"
Seoha's expression went cold as she looked at her sister's despairing face.
"Oh, is that so? Then you can just stay like that for about an hour."
The moment she finished speaking, the chill vanished as if it had never been there. She turned to me with a smile so warm it looked ready to melt.
"Dan-woo♥"
She leaned in to meet my lips — and then:
"I-I'll do iiit!? C-clit masturbation... hieek! I'll do it sooo...!"
Seoha's face went blank again as she looked at her sister. Seoyeon slowly took the hand that had been pinching her nipple and slid it down, hiking up her skirt. Her white panties were shoved aside from all the fingering, leaving her pussy completely exposed. One hand stayed buried inside her. The other settled over her clit. She pulled the skin back and bared the little bud that had been hidden under its hood.
"Nngh... hah...!"
Her trembling fingers crept into place until they rested on top of it. Then she pinched that tiny bean between her thumb and forefinger.
"Higiiik!? Nngh! Hyuuh! Hghhk!?"
Seoyeon convulsed, making sounds no woman should have been making. Seoha watched with open satisfaction, then gradually lowered herself.
"N-noona? What are you doing?"
"What do you think? If I go down from here, what else would I be doing?"
She stopped right above my cock, looking up at me. If she dipped her head any further, her lips would touch it.
"To think the day would come when I'd take a cock in my mouth..."
A smile spread across her face — the kind of sultry look a succubus in a story might wear — and she pressed those plump, springy lips to the tip of my glans.
"Chup..."
"Nnh... this feels weird."
It was a kind of kiss. A peck, except the subject had shifted from lips to the head of my cock. It wasn't so much good as simply strange. What did feel good was the sight of someone as pretty as Seoha on her knees, bent at the waist, pressing her mouth to me. It scratched a faint itch of conquest.
"Your face right now is adorable. Mmh... slurp..."
"Hah! D-don't suddenly put it in your mouth!"
Well. I was the one being conquered, if I was honest.
She took the head between her lips and started licking it this way and that. It was a sensitive spot to begin with, and having her suck and lap at it made every nerve stand on end.
"Chuup...! Pwah... why is it seriously this big?"
"You don't like that it's big?"
"Who said I don't like it? I like it, that's why!"
She grinned and let a string of spit fall along the shaft. Thick saliva that had gathered while she sucked the head wrapped around my cock and ran down.
"I don't think I can fit the whole thing in my mouth. I'll take care of the shaft with my hands!"
She took the head back between her lips and started stroking the rest of the length. She sucked it like a lollipop, putting on those wet, filthy sounds on purpose.
"Wait, noona! If you suck it like that...!"
"Hehe. It's twitching so much..."
She laughed like she was having the time of her life and flicked her tongue against the slit. That unfamiliar jolt, the way it made my hips twitch, sent the urge to cum surging up fast.
Ha. Maybe I should've told them I can only go once.
I'd already said I could ejaculate several times a day, which was exactly why she was trying to wring it out of me without a shred of restraint. Even if I claimed it was a lie now, they wouldn't believe me.
"What are you thinking so hard about?"
Before I knew it, Seoha had left my cock and come up beside my face, her voice a whisper against my ear. She licked along the rim as she spoke, then slipped her tongue straight into the canal. The wet sounds traveled through my eardrum and went right for my brain.
"Pwah... don't hold back...♥ Just cum like this. Spurting it all out♥"
"Nngh!"
Those words were the trigger. The orgasm I'd been holding back tore loose. Semen surged up the shaft, shot high, and fell. Most of it landed on Seoha's hand and the skin around it. Some of it splattered onto Seoyeon, still working herself beside us.
"Ah, nooo!? Semen! Hghhk♥ The smell of semeeen...!? Gah! I'm cumming agaaain♥"
Seoyeon brought the streak on her arm to her nose, breathed it in, and came on the spot. It was the hardest she had convulsed all day. She collapsed forward, one cheek pressed to the mat, her ass in the air, trembling. Her skirt had ridden down and left her white backside bare, shivering — I stared at it, a little dazed.
"Hih...! Higik...!"
"Unnie's completely broken..."
I actually wanted to know. Why did she talk like she'd walked straight out of a manga? Seoyeon's display had been so much worse than I'd expected that the air had gone a little awkward, and I used the gap to ask.
"The way she talks? That's... because what we can watch is limited?"
More precisely, she said, among visual media the material that could actually take the edge off was limited. Clamp down on it too hard and the frustration would pile up and the crime rate would climb, so the people in charge loosened the rules even knowing exactly what they were doing.
"So you watch a lot of it too, noona?"
"W-well, yeah? Not every single day, but about five times a week."
Seoha scratched her cheek, embarrassed to be talking about it. A thought snagged on me. How would someone who'd learned sex from manga actually behave when she did it for real? Right now she had the composure of someone who thought she held the reins. What happened when that composure ran out? How would she react then?
"Huh? What, you already recovered... hwaang!?"
I slid my hand up under Seoha's white tennis skirt and found her already sopping wet. It hadn't been this bad when I'd been touching her a moment ago. I pressed my index finger against the clit poking up through her panties, and a cute little moan slipped out of her.
"Are you a doll? Press you and you moan?"
"Y-you! Hyah!? D-don't press iiit♥"
She scowled at the joke — and then I pressed a few more times and she melted anyway. Se-ah had been sensitive, but Seoha seemed about the same. Maybe it was like the way some women's wombs descended easily, or the way some of them felt everything through the womb. Maybe women were just that sensitive to sexual stimulation itself.
"I've been thinking."
"A-about what?"
She grabbed my hand with both of hers and still didn't shake it off.
"Shouldn't family share the punishment for each other's mistakes?"
"Th-that's not a thiiing!? Higit♥ N-nooo!"
I pinched her clit and her back arched like a bow. Not an orgasm — just shock from the sudden jolt.
"Right now you're an accomplice who stood by and watched, aren't you? Even a stranger would share the punishment for that. So what about family?"
"I tried to stop her! You saw it too, Dan-woo! So this h-hand... hgk!"
I flicked her clit with a sharp little snap. She could refuse all she wanted. The punishment was already decided.
"Spread them. Now."
"Th-this is weiiird... I heard men just lie there... nnh♥"
If she was going to assume I was like every other man, she should have said something when I told them I'd take them both for conception duty at the same time. It was already too late.
Hesitating, Seoha lay back on the mat. I caught the legs she was trying to open into an M and pulled them wide to either side, the way you'd do the splits on the floor.
"W-we're doing it in this position?"
"Why? Is it hard? You're a yoga instructor, noona."
"It's not that it's hard..."
Her legs fell open and the skirt flipped up. Inside, her white panties were so soaked the skin showed through, greeting me like something obscene. Pulling them off and spreading her all over again seemed like a waste of motion, so I just tugged them aside. Sex with clothes still on had a different flavor of heat than stripping down completely.
"Just asking to be sure — did you break your hymen?"
"Yeah... I tore it with a dildo, but..."
Good. If her pussy had never been touched at all, the way Se-ah's hadn't, I would have had to take more time. Not that I would have minded. I just intended to draw a hard line between conception duty and sex between lovers. Put simply: sex that followed desire, and sex that showed consideration. The law being what it was, I figured I was allowed this much selfishness.
"E-even so, it wasn't this big a size! Slowly... higiiik!?"
I rubbed myself against her, coating the head in her slick. She was still babbling something. I grinned at her, then shoved in to the root in one stroke.
"Wait!? Hgk! Hhk! This is weird! This is weiiird!?"
"What's weird about it? You already tasted it yourself."
"That's not what I meeean! Nnh...! Hnnh!"
Seoha shook her head from side to side, trying to fight the pleasure. I teased her breasts through the tight shirt and steadily picked up the pace. Her body started taking it, and her moans climbed with it.
"Hwoht! Hgk! Nooo♥ The woman...! The woman's supposed to be the one moooving♥ hoook!?"
Her body had begun to accept it smoothly. Her head was still refusing. She had to be lost — thrown into a situation that ran completely against everything she'd been trained to believe her whole life.
"Just accept it already. Keep being this stubborn and I'll punish you too, Seoha."
"Hwaang! Nooo! Don't punish meee♥ I'll be goood! I'll accept iiit♥ hghhk!?"
I was already pounding her under the name of punishment, but she understood what I actually meant — the same sentence I'd handed Seoyeon. She surrendered without a shred of hesitation and let the situation take her.
Why had she fought it that hard? Seen through the lens of my old world, it was a virgin guy trying to seize the upper hand while having sex with an incredible beauty, only to get eaten alive instead. A scratch on a man's pride, more or less.
"M-my wooomb♥ Not my womb! If you thrust like that... aaahn!"
Maybe because her heart had given in, her womb finally came down. It seemed it descended easily — but if she didn't want it to, it might not come down at all. Every time the head kissed the opening, the mouth of her womb clung to it like it didn't want to let go. I drove into it without mercy.
"Stop! Stooop♥ My womb! It's getting crusheed♥ hoook! hogook!? hnnh!"
The moan she let out the first time I stabbed into her womb startled her so badly she clapped a hand over her mouth. Even she must have thought it was too filthy a sound.
"Noona. Take your hand away."
"Nngh! Eungh...! Hghhmp!? Hwaang♥ hah! I-I'm sorry!"
I forced her hand off and the moan burst out of her. Tears welled at the corners of her eyes as she thrashed her head from side to side. I wanted to torment her more, so I shoved her shirt up and grabbed the breasts I'd bared.
"Oohh...!"
"Hah! Ukh! M-my chest! You can touch my chest sooo♥ hyut...! ukh, ooohk! hgk!"
"I can touch them, so what? So I should thrust even harder?"
I picked up the pace a fraction and she shook her head even harder. At that rate I was half-worried she'd snap her own neck.
"No! That's not iiit♥ hogk♥ You can touch my chest! Please! Please just go a little sloweeer!?"
Another impossible request. I pinched both of her nipples. I'd meant to grab her breasts whole and use them like handles.
If she puts it that way, it's not like I have a choice.
So I used her nipples as the handles instead.
"Wh-whyyy! Why the nippless♥ higik!? I-if you pull them like thaaat♥"
"Don't pretend you don't like it. When I pull them like this, your pussy clamps down."
Pinch and pull, and those full breasts stretched right out with them. It was fun on its own — but more than that, her insides squeezed tight every time I did it. Seoha was already plenty tight from all the training, even if she wasn't quite at Se-ah's level. When she clenched down even harder on top of that, the urge to cum piled up fast.
"Is this your limit, noona? All that talk about being a famous hunter trainer. You haven't even trained down he— hiek!?"
I was getting close myself, but I didn't stop needling her with words. She was past the point of talking back, but her body was still answering the way it had from the start. Even now, what I said made her clench down around me.
I was holding the orgasm off and tormenting her when a sharp, unexpected jolt of pleasure lit up my own nipple. The surprise knocked the last of my control loose, and everything I'd been holding back spilled out of me.
"A-ahaahn♥ It's coming iiin...! It's so hooot♥ Semen's going into my baby room! Hieeek♥"
Seoha murmured it like a line from a manga, her tongue completely slack. The thing I'd been curious about had its answer — but I couldn't spare it any attention. The hand still pinching my nipple was rolling it in slow circles.
"Wh-who is that! Nnh!?"
"Did you have fun teasing your noonas like that?"
The voice came from behind me. It was Seoyeon — composure restored, her original way of speaking back in place as if the last hour had never happened.
