It's Okay, I've Always Wanted to Marry You Too
Whoosh...
"......."
Aside from the sound of the shower pouring down, only a suffocating silence remained. I was at a loss for how to explain this situation, so I squeezed my eyes shut. My mind had long since reached its limit from extreme exhaustion. I no longer had the mental strength left to scrape together any more excuses.
"......"
My younger sister kept her head bowed low, so I couldn't see the expression on her face. She stood stiffly under the cascading water, and only after a long while did she stammer out, "....T-then... I'll wash you, so just stay still, Oppa...."
"Y-yeah..."
While she had been standing still, the body wash in her hand had been completely rinsed away by the water, so she squeezed more onto her palm. Then, still without lifting her head, she approached me with movements as mechanical and jerky as a robot. Soon, she crouched down in front of me and began to meticulously rub the soap-filled lather onto my legs. As she moved higher up my thighs and finally faced my fully erect penis head-on, she flinched and jerked back in surprise.
"Ngh...."
Her face flushed bright red like a tomato, and it felt as if hot steam were rising from her head. Although we had bathed together almost every day, this was, naturally, the first time she had seen my fully erect penis. It was enough to shock anyone to see the soft, fleshy mass she had playfully rubbed against her bottom every day without knowing any better, now standing stiff and filled with crude, male lust.
She seemed to be contemplating how to touch it, holding her hands awkwardly in the air and swallowing hard repeatedly.
"....T-then... I-I'll wash it...?"
She muttered in a trembling voice, and finally, she began to gently rub my testicles with her hands to work up a lather.
"Ugh.... Ngh.... Ugh...."
Because the aphrodisiac had made my testicles extremely sensitive, her meticulous touch on every nook and cranny made my penis rise even further, twitching in a most lewd manner. I leaned my back against the wall, gripping it with my hands, and let out a low groan as I tilted my head back toward the ceiling. Hot steam rose like a thick fog before my eyes, blurring my vision.
My sister couldn't take her eyes off the penis, which was nearly as thick as her own wrist, staring at it endlessly with her mouth hanging open. After rinsing my testicles for nearly five minutes, she squeezed new body wash into her hand and carefully gripped the hard shaft of my penis.
"Haa-ngh...!"
"S-sorry, Oppa...! Are you okay...?"
She was flustered by my gasping groan and apologized in a hurry. But even so, she didn't let go of my penis. As her warm hand, covered in slippery foam, touched my already extremely sensitive member, I almost ejaculated right then and there, just like before. Whether it was fortunate or unfortunate, Nayeon's mother's relentless, continuous milking just moments ago had left my testicles completely empty, so there was no semen left even if I wanted to release it. Thus, I was barely able to avoid the ultimate humiliation of spraying semen the moment she touched me in front of my sister.
However, while I managed to avoid ejaculation, the pleasure that made my body tremble remained just as intense. I gritted my teeth, holding back my groans, and stared wide-eyed at the ceiling. Meanwhile, my sister, unaware of my internal struggle, was entirely focused on washing my penis thoroughly and taking every opportunity to inspect it.
Starting from the base, she traced each thick vein one by one, slowly moving upward until she finally reached the skin inside the foreskin of the most sensitive glans. Right in front of her small face, the tip of my obscenely massive glans twitched and pulsated. She swallowed hard, then slowly reached out with her slippery hand and began to gently rub the glans.
"Haa.... Haa..... Haa....."
I breathed violently, my chest rising and falling with each heavy breath. Soon, she became bolder, moving her hand to scrub every corner inside the foreskin covering the glans with body wash.
Splash...
Having finally finished washing every inch, she placed her hands on her knees and slowly stood up. Her knees were bright red and swollen from kneeling on the hard bathtub floor for so long. But even then, she was so completely captivated by my penis that she didn't notice it at all. Soon after, she used the showerhead to meticulously rinse the foam off my body. When she washed the foam off my penis, she unconsciously reached out to stroke it, watching with longing as it twitched whenever the water hit it.
After rinsing off all the foam, we filled the tub with hot water and bathed together, just as we always did. My sister sat huddled on my thighs with her back to me, as usual. However, she didn't chatter away or play her usual prank of rubbing her bottom against me.
"....Hah.....?"
Every time my hard penis accidentally brushed against her bottom, her eyes would widen, and she would shiver, pulling her knees tightly together. The ears peeking out from her wet hair were bright red.
A long time passed, and when the long bath finally ended, my sister and I dried ourselves with towels and quietly returned to our respective rooms. I worried about whether my sister would treat me awkwardly from now on because of today's events, but I was so exhausted right now that I had no energy left to think about anything else. I laid my heavy body, which felt like it weighed a thousand pounds, onto the bed and was immediately swallowed by the encroaching sleep.
...That dawn.
I, who had been sleeping and snoring lightly from exhaustion, suddenly woke up at the sound of my bedroom door opening slightly. But perhaps because I was too tired today, I was struck by sleep paralysis; my mind was awake, but I couldn't move a single finger. I could only watch from the darkness as my door opened softly and an unidentified intruder crept toward my bed. Fortunately, as the intruder drew closer, I could easily recognize who it was by her silhouette.
'...Ah, it's Hyun-jung... Did she have a nightmare?'
Since it had happened often recently that my sister would have a scary dream and come to sleep with me, I didn't think much of it and tried to drift back to sleep. But instead of lying down next to me to sleep, she stood by the bed, staring at me blankly, breathing heavily as if she were extremely excited.
"....Haa.... Haa....."
She waved her small hand in front of me and called my name softly, as if to check if I was asleep, but paralyzed as I was, I couldn't respond at all. Finally, judging that I had fallen into a deep sleep, she boldly pulled back my pants to expose my penis and gazed at it to her heart's content.
'...H-Hyun-jung....? What are you doing right now....'
I screamed in my head in utter panic, but of course, it couldn't reach her ears. She rubbed the penis, which had gone flaccid while I slept, with her fingertips until it stood stiff again. This time, without any sign of embarrassment, she narrowed her eyes, smiled deviously, rested her chin on her hand, and watched my penis to her heart's content.
Soon, she glanced at the sleeping me, and a moment later, she muttered to herself in a voice barely audible.
"....Oppa, I saw it all in sex-ed class too... They said a man's penis gets this big in front of the woman he wants to impregnate with his sperm? Hehe, I never dreamed that Oppa thought of me that way.... Honestly, I was a bit flustered at first, but I'm okay now. Because I've always wanted to marry you too, Oppa..."
Then, she rummaged through her pocket and pulled something out. It was dark, so I couldn't see it clearly, but from the silhouette, it looked like a 15cm ruler from a stationery set. She swallowed hard and muttered as she slowly brought the ruler to my penis.
"....I read in a book that for me to have a baby with Oppa, this has to go inside my body....? I need to get used to it before then, so I'll just check a little..."
Then, she began to measure the length step by step from the base of my penis. Since she couldn't measure it all at once with a 15cm ruler, she measured from the end and continued it to estimate the length. After measuring it all, she frowned, compared the 23cm length with her hand, and tilted her head in slight confusion, as if flustered.
Then, to confirm, she bowed her head and placed her hand from between her own legs to gauge the 23cm length. When she finally realized that this size would reach almost right below her solar plexus, she was so shocked that she covered her mouth and shook her head from side to side.
"N-no way, h-how can I put something like this inside...! Are you crazy? Are you trying to crush my uterus, Oppa?"
She shook me, who was sleeping, and got angry for no reason, but soon she ran out of the room like a rabbit, her face pale.
'...Ah, I'm screwed.... There's been a serious misunderstanding...'
However, without even a chance to correct the misunderstanding, an irresistible wave of sleepiness washed over me, and I was slowly sucked back into the depths of sleep.
