D-Day 996 (4): The Vivid Female Body at My Fingertips

The vivid female body at my fingertips. The contact of skin against skin was far more intense than I had expected. Her skin was smoother than I imagined, and when I pressed down with any real force the way it sank between my fingers felt endlessly fragile. The heavy, full volume transmitted through my entire palm. It was like squeezing a large mass of jelly—compressing yet somehow resilient, possessing a strange elasticity. And at the center of it all, the nipple. Or, to use the cruder term, the teat. It was a little larger than my own as a man. Roughly the size of my pinky finger. I shaped my thumb and index finger into a pincer and pinched it.

“Ughk!”

Because it was such a sensitive spot, a bizarre little shriek burst from my sister’s mouth. Her entire body had been locked rigid with tension; now she lost her balance and unconsciously melted against my chest.

Oh, give me a break. There had never been any atmosphere to speak of, but watching her flail like a frog flipped on its back was so ridiculous I nearly burst out laughing.

“J-just a second…! S-Seojin! Ah…!”

I ignored her plea and yanked her shirt up to her collarbone. Moving around inside her clothes had simply been too annoying. Not knowing what to do, my sister stiffened her spine again and tried to pull away from me. In the process the palm I was using grew slightly damp. Sweat. Cold sweat born of embarrassment and nerves, perhaps. Mine, hers, or both. Any of the three would have made sense.

“It’s inconvenient to touch you like this.”

“E-even so… just a l-little…”

What the hell does “even so” mean? As if touching her was now the natural order of things.

“It’s not even cold.”

For the sake of her training I pressed the nipple caught between my fingers and tugged it forward.

“Hngh…!”

Her body went rigid as she tried to mumble something. Not that she had any intention of giving a proper answer anyway. She always stuttered, and even then she could never finish a sentence, swallowing the rest in a vague mumble.

“Eut, haa, haa, mmm…”

Eventually, as if half giving up, only weak moans leaked out between her lips. It wasn’t the sound of pleasure. It was closer to someone desperately holding back a scream. Maybe she was simply repulsed by the fact that her own brother was molesting her. I didn’t particularly care.

The technique of a virgin whose entire sexual education had come from porn and manga couldn’t be anything special. Even if I understood the theoretical mechanics, if simply watching were enough to master the real thing, every basement-dwelling keyboard warrior who enjoyed sports broadcasts would be a national athlete. Besides, everyone said porn and reality were completely different.

I gave up on any clumsy attempts at technique and simply focused on the real, living body of the woman I was touching for the first time.

…, Her breasts really are huge. For a fatty like her.

“Eut…!”

Until now I had never once seen my sister as a woman. I wouldn’t say never, but any awareness had come from the simple unfamiliarity of the opposite sex, not from any sexual attraction. From childhood she had simply been a pitiful creature living under the same roof. So pathetically submissive that I could treat her roughly without fear of consequences. I had my own tastes. I preferred slim bodies to fat ones, pretty faces to ugly ones. Perhaps as a reaction to growing up beside a half-Ukrainian with distinctly Western features, my ideal type had become elegant East Asian women. That preference remained even now that I was older. An uninvited guest who had simply rolled into ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠my life. That was all she had been. Had it not been for the sudden decision that came to me, I probably would never have spared her a second glance.

The strange system. The thought that I had to do something. My sister’s weak personality, which I had observed and analyzed for a long time. The deeply rooted hierarchy between us. And the special, closed environment of living alone together in a narrow one-room apartment. When all those factors overlapped, the lack of hesitation was almost startling. Because I had always looked down on her as a pig-like bitch, I had wondered whether sexual desire would even arise, but that worry proved groundless. A man’s body was more honest and vulgar than I had given it credit for. Therefore my decision and my actions were lightning-fast.

“Hey. When are you planning to move out?”

“H-huh…?”

“Don’t play dumb. Aren’t you going to look for a job?”

“Aaaah… t-that is…”

My left hand continued stroking her belly, moving lower. The sudden, out-of-place interrogation ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠at such an unexpected moment left my sister visibly flustered. Well, it certainly wasn’t the sort of line one would utter while squeezing their sister’s breasts.

“How long are you going to live as a freeloader? Huh? Answer me.”

“……”

“Just looking at you pisses me off.”

I deliberately laced my voice with sharp disgust. My sister shrank her shoulders as if my words had stolen her breath. It was cheap gaslighting, but it worked perfectly.

“S-sorry…”

Below, my sister wore only panties. She must have taken her pants off under the blanket. I stroked her smooth thighs, lowered my head, and brought my lips right next to her ear. My breath naturally tickled the shell of her ear.

“You masturbate when I’m not home, don’t you?”

“…, Y-yes. … Y-yes. A-ah, ehh, aaah, no. I-I didn’t…!”

“Don’t lie.”

I shoved my finger straight into her panties. A thick handful of pubic hair brushed my fingertips.

“Hiiik!”

What I said was true. My sister had masturbated a few days earlier. As an adult she was perfectly capable of it. She didn’t do it often, but she did do it. I simply recited the exact records displayed in her status window.

“The day before yesterday, when I was out, you did it alone. Right?”

“…, I-I didn’t. N-not that…”

“Hey, I know everything, so stop being annoying.”

“Uuu…”

“You lay right here and did it. While watching your phone. Didn’t you?”

Perhaps from shame, the ear pressed to my lips grew hot. I slowly swept downward through the coarse bush. The prickly texture of her pubic hair tickled my fingertips. I whispered even lower.

“What kind of video were you watching?”

“…, It’s not.”

“What do you mean it’s not? You like watching women give blowjobs. A woman licking like a dog. That’s your thing, right?”

“I-I don’t like that kind of…”

“Getting excited seeing them squirt every time they get fucked—what bullshit. Wow, do you watch the ones where they cry while pissing themselves too? What a total pervert.”

I felt her body go rigid in my arms.

“H-huh?”

The status window showed everything. When, where, what, and how she had masturbated—every detail. The genre my sister mainly indulged in was almost always the type where the woman unilaterally served the man. Scenes of women fawning, kneeling, submitting completely, like slaves. Having lived her whole life under oppression, or perhaps because her brain had been pickled by severe abuse, my sister had constructed a sexual preference that drove her even deeper into the abyss.

Of course, it wasn’t definitive. Just as very few people who ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠enjoy netorare actually want to experience it themselves. It could simply be that she became aroused by stimulating material. Whatever. It didn’t matter.

“Did it feel good?”

I gripped the hair hard.

“A-ah, it hurts…!”

“While I was out working, you got to lazily rub your pussy. That must have felt nice, huh?”

“…, U-uuu.”

“Since your brother earns every penny and feeds you, the world seems easy, right? Because I keep quiet and endure, I look like a pushover? Is that it?”

“N-no. I-I just…”

“…, You’re wondering why I’m suddenly acting like this? Hm?”

“……”

“It’s fucking annoying. The more I thought about it, the more it pissed me off.”

“……”

“While some people work like dogs, why do you get to live like this?”

“I-I…”

My cold words must have cut deep. My sister couldn’t continue and began to sob. Outside I could barely speak a word to any woman, yet at home I was a basement-dwelling tyrant. A shallow wave of self-loathing and the realization that I was garbage flickered through me, but it vanished almost immediately. Well, that’s just how it is.

“Hey. Take off your panties, spread your legs, and lie down.”

“Huh…?”

“Take them off. Spread your legs. Lie down.”

“……”

Her slightly trembling back pressed fully against my chest.

“You know what? Ever since you moved in, I haven’t been able to masturbate properly. Huh? Don’t tell me you didn’t know.”

“Uu…”

“You knew, didn’t you? That I do it in the bathroom. It wouldn’t make sense if you didn’t, fuck.”

“T-that is…”

Even my sister, with her low sex drive, masturbated. So what about me—a healthy man in his twenties who prided himself on having a normal libido? Ever since she crawled into this tiny room, I had to turn the water on in the bathroom or blast music from my phone and sneak it in while constantly watching her mood. I couldn’t exactly kick her out just to jerk off, nor could I announce it openly. And whether it was a weekday or weekend, workday or day off, my sister stayed glued to the house like a ghost.

The things I used to do comfortably every single day in my own home, I now had to do like a rat hiding in the shadows. My complete personal space had been utterly castrated, and that too was one of the terrible stresses caused by her very existence. There was no denying that this was also part of why I craved her.

“Does that make any sense? The homeowner having to watch the tenant’s mood before he can masturbate? While someone else comfortably eats and sleeps on money her brother earns and just scratches her pussy whenever she wants. So fair, isn’t it?”

“S-sorry…”

“Sorry? Do you really mean that?”

“I-I was w-wrong.”

Her stuttering voice sounded on the verge of tears. Without offering a single proper objection, my sister simply repeated that she was sorry.

“Then help me.”

“…, Huh?”

“I said help me with it. You can’t earn money, you stay home all day, you only masturbate. Why should I feed and support a useless bitch like you? Then at least take care of your brother’s sexual needs. Don’t you think?”

“……”

“You have no experience anyway. I’ll do it for you.”

Anticipating the next words, she shrank again.

“If you understood, take off your panties and lie down. Then spread your legs.”

“……”

“You don’t want to? Then get out.”

“……”

“Do whatever you want. I don’t care.”

“……”

How much time passed? My sister finally rose.

“…, I-I.”

“Hurry up.”

“……”

She slowly moved away from me. After hesitating for a long moment, she eventually bent and removed something. A wriggling silhouette in the darkness. My eyes had grown used to the faint light slipping between the blackout curtains. I could faintly make out her every movement. At last she took off her underwear, timidly sat down, then lay back.

“Spread your legs too.”

“……”

No answer. Instead, her thighs quietly parted.

“…, I’m going to do it right away.”

I didn’t know anything about foreplay. I just wanted to get inside her first. Like my sister, I usually slept in nothing but underwear, so I roughly discarded the cumbersome cloth and pushed my body between her spread legs.

“…, Eut.”

Before positioning myself I lightly brushed her slit with a fingertip. A slippery moisture clung to my finger, but I couldn’t tell whether it was sweat from tension or the so-called love juice I had only heard about. It was too dark to see. I could only vaguely sense the shape of her pussy. The plump mound was unbelievably soft. Softer even than her breasts. Maybe because she carried so much fat.

I pinned one of her thick thighs down with one hand and used the other to search for the entrance. The slightly protruding part—was that the clitoris? So this is what it feels like.

“……”

Carefully tracing the complex, intertwined curves downward, my finger finally caught on a sunken crevice. It was located much lower than I had imagined. When I applied a little pressure to the entrance, my sister’s breathing suddenly fluctuated.

“A-ah, it hurts…”

Here it is. I felt as if I had found a clear landmark.

“Endure it.”

I scooted forward on my knees. I withdrew my hand and grasped my painfully erect cock. Since I knew the rough location, I figured I could insert it even without seeing. I pressed the hot mass against the damp flesh surrounding the hole and began rubbing.

Going straight to penetration after only lightly groping her breasts might seem like the act of a brute, but it couldn’t be helped. I had no real technique, and if I fumbled awkwardly and ended up hurting her, how pathetic would that look? In any case, this was the path I had decided on for her.

“……”

“Hiiik…!”

The tip of my glans caught on a concave spot. That place from earlier. Now I just had to thrust.

“……”

“……”

We exchanged no words. Only the sound of breathing, echoing our heartbeats, filled the room.

I hadn’t put on a condom. I had intended to go raw from the start, but my sister offered no objection. She was probably too flustered to think of it.

“…, I’m going in.”

From this moment on, there would be no turning back. Until now we could have glossed it over by telling ourselves we were still just siblings. Hmm. What now?

“…, Ugh.”

But I was rock hard.

Squish. The sound effect played only inside my head. My cock pried open the narrow entrance and pushed inside. Her insides were hot. The wrinkled mucous membranes softly compressed my length, making way.

“Aaaaaaaaah! Ah…!”

My size wasn’t anything impressive. Just a little above average. Yet because it was her first time accepting such a large foreign object, my sister thrashed wildly, screaming as if she were being torn apart.

“It hurts, it hurts, it huuurts!”

“Sh-shut up…!”

Slap. Slap. The dull sound of flesh striking flesh tore through the sealed darkness.

“Aah, ah, ah…, uup, uup!”

“…, Be quiet.”

Fearing the noise would leak out, I clamped my palm over her mouth. It was an old villa one-room; even slightly loud sounds would carry to the neighboring unit. Through my hand I felt her panting breath and terror-filled moans, muffled and broken.

“Huk, huk, ugh.”

“Uup! U, puheup…!”

“F-fuck…!”

She hadn’t seemed very wet before insertion, yet I was able to move without much resistance. With one hand I kept her mouth covered to control the screams; with the other I frantically groped her heavy, swaying breasts. This was sex. This was real sex.

“Huuk, huuk.”

How much time had ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠passed? It didn’t feel like I had been moving long, yet sweat poured from my entire body. Lack of exercise was part of it, but this turned out to be an incredible full-body workout.

“U, aeu, ugh, ugh…”

The initial tearing pain seemed to have subsided somewhat. My sister’s voice grew quieter.

“Huk, huk, so fucking good, fuck. Huk…!”

After that came only my rough breathing. My sister neither placed her hands on my waist nor wrapped her legs around me. She simply lay there like a bitch in heat, quietly accepting everything. On top of that defenseless body I thrust my hips like a madman. Soon my lower abdomen grew painfully tight and the limit approached.

And then—

“I’m cumming…!”

“…, Uup, uup, ubup!”

“Ugh…!”

My body trembled on its own as if struck by a powerful current. The pleasure was so intense it felt like my brain was melting; I couldn’t even tell whether I was ejaculating or pissing myself. Was it the excessive excitement of my first time? Or the situation of violating my own blood-related sister?

“Huu…”

“Uu…”

Listening to my sister’s moans from beneath me, I gently rotated my hips to soothe my overly sensitive glans right after climax. The sticky sensation of her pussy clinging to my cock was vivid. I squeezed out the very last drop and poured every bit of semen into the deepest part of her.

After that, we did it one more time.
