When I came to my senses, I was already inside her. I felt no regret, though there was some guilt for crossing a line. I could feel my siste.r's love in her tight pu$$y that didn't want to let go. Though this may be wrong, to survive in this world of twisted common sense, there's no time to hesitate here. It's definitely not because my siste.r's pu$$y feels better than expected!
"Sis, I'm going to start moving."
"Don't worry about me. I'm satisfied as long as my beloved brother moves how he wants."
"..."
Experiencing my siste.r's kindness for the first time, as her hot womb touched the tip of my penis, the brakes of common sense broke down completely.
"Sis! Sis!"
"Ahh! My brother's childish thrusts! My womb is getting pounded!"
Squelch! Squelch! Squelch!
I thrust my hips while burying my face in her chest. I can no longer control myself. I decided to truly mate with my siste.r - no, with Seowoo.
Her lewd pu$$y sprayed fluids with each thrust. She clung to me so tightly, her pu$$y followed my penis to the limit each time I pulled back. There's no reason not to use such a lovely pu$$y.
"Does it feel that good?"
"It feels so good, it makes my 27 years of life seem wasted!"
"Then I'll pound you so you don't feel like you've wasted anything!"
"Ahh!"
Squelch! Splurt! Squelch! Splurt! Squelch! Splurt!
With each thrust, fluids gushed out. The room filled with a lewd scent. Seowoo's breasts bounced enticingly with each movement of my hips. I sucked on her nipples like a fish caught on bait.
"Suck suck."
"Ahh! Getting my nipples sucked while being pounded feels so good I might break!"
Seowoo let out vulgar moans. Her usual prickly demeanor was completely gone. She panted like a female animal in heat. I felt greedy. I wanted to make this woman mine. My hip movements sped up with that filthy desire. There was no trace of consideration, just rutting to dominate a female. Seowoo's moans grew louder.
"Ughh! I'm dying! I'm dying on my brother's dick!"
"Why are you dying! Don't you need your brother's dick?"
"I need it! I need it so pound me harder!"
Squelch! Squelch! Squelch! Squelch! Squelch!
I pounded Seowoo's womb forcefully, as if trying to break the desk.
Bang! Bang! Bang! Bang!
The sounds of flesh slapping together rang out. I was going to make Seowoo my woman now. I put more force into it to prove that. It was rough mating that was hard to believe was between siblings. We desperately sought each other, spraying fluids everywhere. Our breathing grew rougher as we touched. Our expressions melted in pleasure.
"Sis, I'm going to cum!"
"Yes, do it! Fill your siste.r's womb with your thick semen!"
"Ungh!"
"Ohhh!"
Spurt! Spurt! Spurt! Spurt! Spurt!
My penis throbbed as I released everything into her greedy womb that sucked out every last drop. Not a single drop remained in my urethra. I'd never felt so drained after ejaculating before. Whether it was because Seowoo and I were so compatible, or the guilty pleasure of crossing a line, I knew I'd never forget having sex with Seowoo.
We gazed at each other silently, catching our breath. The lewd flower that had fully bloomed as a female was truly beautiful. When I gently caressed her cheek, she responded with a faint smile as if enjoying even that touch.
"Brother, you did well. I'm so happy today, I don't think I'll be able to sleep."
"What do you mean?"
"Huh?"
I roughly pulled out my penis and semen leaked out. Seowoo frantically tried to stop it with her hands, but I prevented that and pulled her up.
"Sis."
"No! The semen! My beloved brother's semen...!"
"Sis."
I called out to Seowoo longingly and hugged her tightly. She finally calmed down. Then I grabbed her shoulders and said:
"I don't plan to end this with just once."
"Really? You'll use your siste.r's pu$$y again?"
"Of course. In fact, be prepared not to sleep tonight."
"Huh?"
I laid Seowoo on the bed and straddled her thighs. As I rubbed my still-erect penis against her stomach, her cheeks flushed red.
"If you want to refuse, now's your chance."
"..."
"I'm going to keep going until you pass out, no, even if you pass out. Is that okay?"
She said nothing, just nodded shyly. Then she reached out to wrap her arms around my neck, slowly pulling me closer.
"Mmm..."
"Ahh..."
Slurp slurp
We shared a deep kiss with no distance between us. There was no longer any trace of a sibling relationship between Seowoo and me.
***
After the desk, our sex continued on the bed. Holding both hands, Seowoo entrusted her whole body to me and said breathlessly:
"Jinwoo. If you're tired, we can stop..."
"Not nearly enough. No need to worry!"
Contrary to Seowoo's concern, my body was still full of energy. Thanks to the infinite stamina, but also because sex with Seowoo wasn't tiring at all. Is this what love is? I thrust my hips powerfully while intertwining my tongue with Seowoo's.
My forcefully thrusting hips bounced off the mattress. As soon as the rebound disappeared, I thrust my hips down again. It was a motion solely to impregnate the female. I violated Seowoo's womb with the mating press.
"This is dangerous! My womb will be crushed!"
"It's okay if it gets crushed. I'll keep using it!"
"Ungh! When you say things like that, I..."
Splurt! Splurt! Sploosh!
She sprayed fluids again like she was peeing. I stroked her head as if she was cute, and Seowoo blushed and demanded a kiss.
"Sis..."
"Brother's saliva tastes so good. I don't think I'll ever get tired of it."
Do I taste that good? I deliberately spread some distance and sprayed saliva on her face. She even stuck out her tongue to catch the falling drops. Even someone stranded in a desert wouldn't drink so desperately. It was a moment where I could feel Seowoo's love.
"Then shall we change positions?"
"Ooh! I like this. Your dick goes in even deeper!"
I shook my hips with one of her legs over my shoulder. Just as Seowoo said, I hit her cervix more frequently even with shallow thrusts. I violently ravaged her womb and stimulated her clitoris with my free hand.
"Th-there!"
"Where? I can't understand if you just say 'there'."
"My clitoris! You shouldn't play with it like a toy!"
Though she said not to, I could feel her womb rejoicing each time I caressed it. How dare she lie to me. This calls for punishment.
"Take this!"
"Ahh! Unghh!"
Sploosh! Shhhh...
I flicked her clitoris with my finger. A stream of yellow liquid poured onto the floor following the intense squirting. She seemed to have lost her mind from the shock, babbling nonsense with a dazed expression.
"Hehehe. There are two brothers..."
"Don't space out and leave your brother behind!"
"Ohhh!"
Squelch!
She came back to her senses with a rough moan as I pounded her womb violently. But she had no chance to speak due to the intense piston motion, just panting as her breasts shook.
"Hah! Ohh! Ungh!"
"Is it okay for sis to cum? You're giving me permission to cum, right?"
"Haah! Oww! Ungh!"
Spurt! Spurt! Spurt! Spurt! Spurt!
As soon as I got permission, I poured semen into her womb. Her womb swelled beyond its limit. Seowoo's belly visibly bulged out. She looked exhausted, and I thought maybe we should stop here before we end up dying of dehydration if we keep going until morning.
I pulled out and went downstairs for a moment. I grabbed an ion drink from the corner of the fridge and returned to the room.
'This should be enough.'
I only brought one bottle, but the drink itself was large enough for us to share. Just as I was about to return to the room with the drink, I caught Seowoo trying to eat something in her room.
"Sis, what's that?"
"J-Jinwoo, it's not what you think..."
A small box in my siste.r's hand. The word "contraception" was engraved on it in small letters.
"I thought you wanted to get pregnant. Why are you taking birth control pills when you said you wanted to have my child?"
"W-well, when I calmed down... I got the feeling we shouldn't do this."
Seowoo awkwardly laughed as she made excuses. I knocked the birth control pills out of Seowoo's hand, grabbed her wrist, and asked pressingly:
"Why? Is there some law saying siblings can't do it?"
"W-well, there's no such law..."
"Then why are you saying we can't do it?"
"...Huh?"
As if she finally realized something was strange, she suddenly clutched her head and started crying. Could there be a problem with the common sense alteration? Seowoo asked me with an anguished face:
"Why did I do that? Siblings getting pregnant is natural."
"Sis."
I hugged Seowoo. Her shoulders trembled in surprise, but she soon calmed down and nestled into my arms.
"Sis, you don't need to hold back. There's no reason to be in pain."
"I don't have to hold back? Really?"
I nodded vigorously at Seowoo's trembling voice. Although the altered common sense can't be called normal, there's no reason for Seowoo to suffer. If Seowoo is in pain, that's my responsibility to bear.
"Then shall we ask your body too? What it wants to do from now on."
"Ohh! Suddenly fingering my pu$$y!"
Squelch squelch
When I fingered her pu$$y, love juices overflowed. The body is honest even if the mouth says a thousand words. Seowoo's body already saw me as a man.
"Your body says it likes me. Do you dislike me, sis?"
"How could I dislike you! Mmph!"
Slurp slurp slurp slurp.
We shared an intense kiss as if unleashing everything we'd been holding back. She held my face as if never wanting to let go, conveying her feelings through the persistent kiss. In response, I rubbed my penis against Seowoo's belly, and she revealed her current feelings with a slight tremor.
"Shall we go back to the room then?"
"No."
I considered going back to my room, but doing it on the already wet bed would just feel unpleasant. And Seowoo's room was too cluttered to do it there.
"Then where are we going to do it?"
"Curious?"
I took Seowoo's hand and went downstairs.
***
Early morning. I woke up to the alarm for my husband who leaves early. Though I wasn't fully rested, after doing this for over 20 years, it had become a habit. As I got up with my stiff body and headed to the kitchen, I found my husband already awake.
'Hmm?'
But something was different from usual. Normally he'd be reading the newspaper and ignoring me. Today he couldn't take his eyes off something. I turned my head to follow his gaze and saw:
"Ohhh! I'm cumming! Cumming again from brother's semen!"
Splurt! Sploosh! Splurt!
Seowoo and Jinwoo were in the middle of mating. I thought they didn't get along, but I guess I was mistaken. How could they not get along when they're mating so frantically? Especially the clear liquid soaking the floor. That's definitely love juices Seowoo sprayed from a genuine orgasm.
'I'm jealous. I want to get pounded by a dick too.'
I envied Seowoo panting as she was penetrated by a penis. Before my husband became obsolete, he made me cum many times with rough mating. But now he's an obsolete man who can't even get erect. He was nothing more or less than an ATM machine. Still, we had two children, and his job wasn't bad, so I lived contentedly. At least until I saw my children mating.
"Honey, I'm sorry. I'm going to masturbate for a bit."
"Okay."
Hearing my husband's curt reply, I started masturbating using my children's mating as inspiration. Seeing Seowoo and Jinwoo mate got me excited. Just touching myself with my fingers made love juices flow copiously. I fingered my pu$$y without hesitation, letting out lewd wet sounds and moans.
"Hah... Ungh... Huu..."
"Ohhh! Cumming! Cumming again!"
But my weak moans were completely buried under their bestial, vulgar cries. Then, with his penis still inserted, Jinwoo and Seowoo stood before me and my husband. Jinwoo opened his mouth with a grave expression, saying he had something important to tell us.
"I have something to tell you both."
"W-what is it?"
"Mom, Dad. I..."
"I'm going to get pregnant with Jinwoo's child."
'Ohhh!'
Love juices sprayed out at Seowoo's pregnancy declaration. I ejaculated love juices to a degree I'd never done even with my husband, soaking my pants completely. My husband gave a small nod, and the two of them immediately started shaking their hips roughly.
"Ohhh! Watch, Mom! Watch me have a pregnancy orgasm!"
"I'm cumming, Sis!"
"Ohhh! The pregnancy orgasm is here! I'm having a pregnancy orgasm in front of Mom and Dad!"
Spurt! Spurt! Spurt! Spurt!
The ejaculation was so thick I could hear it. I wonder how concentrated that semen is. How good must it feel to make such a shameless face?
'Ohhhh!'
Splurt! Sploosh!
I sprayed fluids in response to Seowoo's pregnancy orgasm.
"Ohh! Ohh!"
I watched Seowoo spurt semen each time she climaxed as she lay on the floor. Firmly resolving that I would be next.
