[Practice Sex (4)]
Is it really safe to take her words at face value when she says, "Living together made me develop feelings"? Is Lee Jiyoon truly interested in the person that is 'me'? Or is she just interested because I happen to be the man attached to her sister's side? Perhaps this is a position that could have been filled by anyone, not necessarily me.
"Haa..., hu..."
"...Ha, ah..., h-hk..."
Jealousy. It wasn't just a sudden thought; it was a dark, brooding jealousy that anyone could see. I convert all of it into sexual desire and pour it entirely into Lee Jiyoon. I teach a woman who doesn't even know how to kiss properly the way I like to kiss. I teach a woman who thinks putting it in her mouth is all there is to oral sex the tongue movements that suit my tastes. I command a woman who only knows how to lie on the bed and take it to climb on top of me and stimulate the spots that feel good to her herself.
When the base of my cock starts to twitch, I push myself up, bracing my hands against the bed. Lee Jiyoon, who had been busy grinding her hips on her own just a moment ago, tries to shyly slip away, but I pull her into a tight embrace and vividly imprint my scent all over her. Her lips. Her neck. Her collarbone. Her upper chest. Then, her lips again. And finally, her cervix. I carve the pleasure that only I can provide into her mind. I give her a silent warning: If the man beside you isn't me, you might never feel this kind of pleasure again.
"Take it easy with the cum...!"
"Just a little more.... Just a little..."
"...Damn it.... I can feel everything through the condom..."
"Haa..."
"I-if you cum that much, what if it rips?!"
"You're so soaking wet down there, it's never going to rip."
"You never know.... ...Ah, crazy, you're cumming way too much, seriously..."
Lee Jiyoon, trapped in my arms and busy meowing her complaints while I cum inside the condom. I stroke her hair, which has dried somewhat, to calm her dissatisfaction. At times like this, it’s amusing because it feels like handling a pet cat at home. One day, I’d like to see her obediently taking my raw cum inside her. Or perhaps, begging for it. If she’s too shy to say it, maybe she’ll hide all the condoms in the house and pretend she doesn't know where they went. Something like that. Of course, seeing as she’s still so diligent about using condoms, it’ll be a long time before we enjoy raw sex. And sex with internal ejaculation during her fertile window will take even longer.
"Haa.... Jiyoon-ah. Take off the condom. You do it."
"I, let me catch my breath for a second..."
"...Forget it. I'll do it, so just rest for a moment. We're going again right away."
"...Eh...? Right away...?"
"Don't want to?"
"..."
"...I can't even ask if you like it because you said I sound like a virgin."
"...You're the one who sounded like a virgin by asking if it feels good.... You idiot..."
"Then, shall we go again? This time..., ...ah. On your hands and knees?"
"..."
"...Pfft."
"D-don't laugh...! Damn it..."
"You're so damn cute, how can I not laugh?"
"What part of me is cute...! ...Ung-geuk.... Ugh..."
I lift up Lee Jiyoon, who is limp from the climax, and pull my cock out. I take off the condom for her, as she’s buried her face in my chest, gasping for air, and toss it to the edge of the bed. When there were only one or two condoms filled with semen, I didn't think much of it..., but seeing the pile—some that Jiyoon had tied the ends of herself to keep the fluid from leaking, and others that I had left untied—about ten condoms in a messy heap, my blood rushes to my cock again.
...Ah, fuck. If all that had gone into Lee Jiyoon's womb, what would she look like right now? That thought keeps crossing my mind.
"...Jiyoon-ah. Reach back and grab a condom."
"...I don't think... I can reach..."
"Then shall we do it without one?"
"Stop with the weird jokes...! Even at that distance, I can't reach it even if I stretch my arm out..."
"...I haven't even done it raw with Hayoon-noona yet."
"...S-so what..."
In the end, Lee Jiyoon furrows her brows, thumps my chest with her fists, and moves away. She tosses a whole box of condoms at me and gets into position. She doesn't go fully prone, nor is she crawling like a dog; she presses her upper body against the bed, lifting her hips just enough to be fucked hard, and glances back at me with a look that says, 'Do men really like this kind of thing?' I dominate her, bracing my fists against the bed, and tear open a condom.
"Lower your hips."
"...Huh? ...B-but don't I have to do this so you can fuck me...?"
"I can fuck you even if you're lying flat, so lower them."
"...Uung."
"And if we have sex in this position, your hips will rise on their own even if you don't want them to. That's how it was with Hayoon-noona."
"..."
At the mention of Lee Hayoon, Lee Jiyoon, who had been lying still, turns back for a moment and then rests her chin on the pillow without a word. I did it hoping she'd be jealous of her sister, but did it have the opposite effect? I brush back my bangs, still not having mastered 'Lee Jiyoon-speak,' and instead of choosing to provoke her further, I gently spread her fissure.
A cherry-blossom pink that matches her white skin perfectly. ...A cherry-blossom pink that is glistening everywhere due to the slick lubrication. I stroke the narrow opening at the very top—a hole that looks like it couldn't even handle one of my fingers—with my fingertip, then slowly push my thick glans, which is incomparable to a finger, into her.
"Maybe it's the position. It's so damn tight..."
"..."
There is no answer. Instead, perhaps trying to relax as much as possible, the pressure of her squeezing my cock eases slightly. ...It meant it felt good because the hole was tight, not that I wanted her to relax because it was too hard to fuck. I find her cuteness—choosing the wrong answer without a moment's hesitation—makes my cock stand even stiffer, and with a satisfied sigh, I push my cock as deep as I can into her.
The feeling of it pressing firmly against my glans is...
"......Ung-geuk.... ...Ugh..."
...until I am certain I am pressing against the back of Lee Jiyoon's cervix.
"T-time... time..."
"...It's been a long time since I've heard that."
"Just stay still.... Stay..."
"I am staying still, why are you like this?"
"Just.... Just understand it..."
"..."
...Well, I can certainly tell that much just by looking at her reaction. She has a constitution that prefers having her cervix crushed mercilessly by a thick cock over using a Womanizer for clitoral stimulation. How could I hold back?
Climax.
"...You came already?"
"......I told you, ugh.... not to ask.... about that..."
"So, did you or didn't you?"
"...Do you think I'd come just from having a cock inside me, you idiot...? It's just that the squeezing gets intense when you push it in that far..."
"Ah, I see."
"...Hey, Seo Woo, wait a second..."
She had been clutching the pillow tightly until a moment ago, but now one of Lee Jiyoon's arms reaches out urgently. I snatch it and pin it firmly to the bed, then—*thwack, thwack-thwack. Thud, thud, thud.* I fuck her as violently as my desire dictates, hard enough to make strange noises against the bed.
"This is... so much deeper than when we did it before..."
"It goes in a bit deeper in this position."
"Phew..., ph... Ah..., crazy.... I should have done it like this from the start..."
"...Anyway, answer my question from before first."
"......W-what words..."
"Are you squeezing because I'm just pushing it in deep? ...Really?"
"...Phew.... Hey, don't put your finger in my mouth..."
"Don't change the subject. Tell me honestly. ...Why are you squeezing so hard?"
"Because you're... pushing it in like that while I'm on my hands and knees..."
"Is that really all?"
There is power in my voice. Especially, it is much stronger in a negative sense than a positive one. There's a reason the word 'brainwashing' exists. The same goes for interrogation under pressure. The word 'gaslighting' didn't rise to the surface just because it was a fresh term. There is power in a voice. Slowly. Slowly. A power that eats away at a person.
"...It's not just because you're on your hands and knees; it's because you love it when I push it in this far, right?"
"..."
"Every time I crush your cervix like this, you climax."
"Hick.... Ung-geuk......"
"...That's why you're always busy with clitoral stimulation on your own."
"...Hey, damn it..., you, how do you know that..."
"How could I not know when your expression gets so lewd every time you rub your clitoris with your fingers. ...Fuck."
"......"
I stimulate her cervix while whispering her inner thoughts, which she can't honestly admit and tries to suppress with groans. Of course, it's fine if there are some slight inaccuracies. A very minor error added to a large amount of truth naturally blends into the truth.
"...You'll feel even better if you admit it honestly. So say it with your own mouth right now."
"...Admit, admit what, admit what...!"
"Say: 'I am a total pervert who can't feel a thing unless a forearm-sized cock is crushing my cervix.'"
I deliberately spout vulgar words that I know Lee Jiyoon will hate, then pull my cock out slightly. And then—*thwump.* *Thump.* As soon as I thrust it back in, I catch Lee Jiyoon's hips as they jump, push it all the way to the root, and whisper in her ear.
"...I can feel you squeezing because you've already come. Hurry up."
"...I've only ever had sex with you, how would I know that...! It could just be... something else causing it..."
"Then can you be satisfied if I only push it in this far?"
I grab Lee Jiyoon's hips, which are trembling from the aftershocks, pull my cock out, and thrust it in only halfway, nibbling on her ear. A depth that barely exceeds the length of a middle finger. It might be deeper than when she masturbates, but that's all it is. After teasing her until she's whining because she's unsatisfied, I place my hand on the head of Lee Jiyoon, who is panting with her cheek against the pillow, and—*thwack. Thwack. Thwack.* I crush her cervix as if to imprint my cock on her forever. Regardless of whether Lee Jiyoon, pinned beneath me, is thrashing her legs. Regardless of whether the sound of her calling my name, "Seo Woojin, Seo Woojin," is leaking out. Regardless of whether Lee Jiyoon, squeezing my cock as she climaxes—*fyu-ut, fyu-ut, fyu-ut*—is adding another water stain to the already filthy bed sheets. I bite her ear, which has turned red amidst her snow-white hair, and fuck her cunt, which is sticky with lubrication, with all my might.
"...You like this better, don't you? Having your cervix crushed."
"...I don't know..."
"You'll feel better if you admit it honestly, won't you? ...I'll only do it the way you like, too."
"..."
"If you like it when I fuck you shallowly like before, I'll do that. How about it?"
"...Damn it......"
Did she forget already, having just greedily accepted my excuse that I like her? Lee Jiyoon raises her head, showing a reaction more like a younger sister engaging in incestuous sex than a girlfriend. As I catch my breath with my lubrication-covered, erect cock resting on her hips, Lee Jiyoon, her face flushed red, whispers one word at a time.
"...Hey. ...W-what did you tell me to say...? I remember 'pervert' at the end..."
"How do you remember that? I just made it up on the spot."
"...T-then what am I supposed to say...!"
"You know, right? Tell me honestly what you like."
"......"
Lee Jiyoon's shoulders rise and fall as she pants. Her snow-white hair is now wet with sweat instead of water. Her straight spine is drenched in the sweat she poured out. While taking in the sight that I never would have dreamed of, I also take in Lee Jiyoon's voice, which flows out hesitantly.
"......I, um, well..."
"..."
"I am..., a total pervert... who can't feel a thing... unless a forearm-sized cock... is crushing my cervix..."
"..."
"...Are you satisfied now? You perverted bas... ...Eh...?"
"..."
"Hey, wait..., calm down, calm..."
"..."
"......, ...?! ....... ......♡…, ……."
"..."
...Like that, leaving a filthy mark directly on Lee Jiyoon's pure white innocence was a terrifyingly thrilling sensation. It was so thrilling that I didn't even realize Lee Jiyoon had fainted from the pleasure, and I had filled the condom to the brim with my semen. With an impossibly thick, creamy semen.
