The Female Body's Submission

My lower abdomen was burning with an uncontrollable, relentless heat.

Thanks to that, my cunt was already leaking, radiating warmth even though we hadn't done anything yet.

Jiyoon stared at that opening, let out a sly laugh, and shook her head. She pulled something out of her bag and said,

"But a cock is still a no-go."

"Wh-why, whyyyy……?♡"

"It’s always tastiest when you hold back and wait, right? So, you’ll have to tease your cunt a little more before you get to eat this cock."

Jiyoon began to slowly rub the dildo she’d pulled from her bag against my opening.

Squelch— squelch—

"Ngh-aaaah!!♡ Oh, ah!♡ Ooh-aaaah!!♡"

Perhaps it was because my sensitivity was through the roof from the aphrodisiac. Even though she was just rubbing the dildo against me, my body was busy gushing out love nectar as if I were already climaxing.

"Hiiik!!♡ Ah, haaaah!!♡ Eugh♡"

"Ah♡ You’re so lewd, Sister. I guess it’s no wonder Mom couldn't hold back."

"Jiyu, ple-ase♡ Hngh♡ Stooop♡"

Pshuuuuuuut!!

"Ngh-hiiiik!!♡"

My body was climaxing over and over again thanks to Jiyoon, but… the heat in my body didn't fade away at all. If anything, it was rising higher and higher, as if I were going to burn up.

"I, I don't waaaant this♡"

"What don't you want?"

"The dildo, I don't want it♡"

I didn't want to be teased with a dildo. I’d rather have a cock. A cock that would pierce me all the way to my deepest depths.

"Heh, Sister. Then what do you want to eat?"

"Th-that oooone……."

"If you don't say it, I'll never know."

Jiyoon pulled another item from her bag. This time, it was a vibrator shaped like a small, round bead. Jiyoon grinned and pressed it against my clitoris.

A sudden, ominous feeling washed over me.

"Ji, Jiyoon-ah…♡ I really don't think this is right♡"

Before I could even finish my sentence, Jiyoon pressed the switch on the vibrator.

Vvvvvvvvvv——

"Khu-ooooooh!?♡"

"What was that, Sister? I couldn't hear you over your lewd moans♡"

Every time the vibrating bead rubbed against my clitoris, a dizzying pleasure followed. Unable to withstand the sensation, my body began to tremble uncontrollably, like a broken machine, and my cunt started pouring out nectar like a waterfall.

"Khit♡ He-eugh!♡ Ah, haak♡ Ogh-hoook!!♡"

"Your moans are so good, Sister. So wanton♡"

"St-stop, ple-ase♡ Ngh-hiiiik♡ K-haang♡"

I couldn't form proper words. How could I? My most sensitive spot, second only to my womb, was being relentlessly stimulated.

"What was that, Sister? You want me to turn the intensity up higher?"

"No no nooo!!♡ If you do that, I'll really die……!!"

Vvvvvvvvvv!!

"Hoooook!!♡♡"

My body climaxed yet again. Simultaneously, a stream of yellow liquid sprayed from my cunt. I couldn't handle the pleasure and had wet myself on the floor.

"Ahaha…♡ Sister, how old are you to be peeing in front of your little sister?"

"Wh-whoooh, made me, th-this wayyyy♡"

"Peeing on the floor is something only little kids do, so you need to be punished, right?"

"St-stooop haaa!!♡"

Ignoring my pleas, Jiyoon pressed the button to set the vibrator to its maximum intensity. The device began to vibrate at full power. With it already pressed against my clitoris… it was only natural that I would be overwhelmed by a pleasure no female could endure.

"Ngh-hiiiiiit——♡♡!!!"

Climax, climax. And another climax. My eyes rolled back in my head from the endless cycle of pleasure. Naturally, my tongue lolled out, dripping with saliva.

"Khu-ooooh♡ Oh-ook♡ H-hot, oooooh!!♡ Ngh-hiiiik!♡"

Overwhelmed by a dizzying pleasure that defied description, I couldn't utter a single coherent word. All I could let out were the lewd, animalistic cries ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠of a beast.

"Sister, Sister. How’s the maximum intensity?"

"Ohoooooh!!♡ Ngh-it, ngh-he-eeek♡ Haaaak!!♡"

"Looks like you love it♡"

Jiyoon stroked her own cock through her skirt with a satisfied expression.

"Then, Sister, let’s try to hold out for about an hour, okay?"

"Hiiik!!♡ He-ek!?♡"

An hour? If I were subjected to this for that long, my brain would surely melt from the pleasure. I tried to escape, knowing I couldn't possibly hold out, but with my hands tied, there was no way to get away from Jiyoon.

"Where do you think you're going, Sister♡"

"Ngh-haaaaaaaak!!♡"

Vvvvvvvv——

"He-eugh, ooh♡ Ohoooooh!♡ Ngh-it♡"

How much time had passed since then? The living room and entryway floors were already drenched in my urine and nectar. It was only natural; I had climaxed so many times I couldn't even count them anymore.

"Uung……♡ You're holding out really well, Sister. Any other female would have fainted by now. I guess you really do have a body optimized for being a female."

Jiyoon laughed playfully and pressed the button to stop the vibrator.

"He-ek♡ He-eeeek♡"

I really felt like I was going to die. To tease only my clitoris for an hour without even letting me have her cock… my lower abdomen was aching so badly I thought I’d go mad.

"Sister."

"Ye-eah……?"

"You can tell me your true feelings now, right?"

My true feelings……. My true feelings were… to have my lovely sister’s cock buried deep inside my cunt, which was already soaked from being teased for an hour.

"……I want you to put it in."

"I can't hear you."

"I want Jiyoon to bury her cock inside her lewd sister's female cunt…♡"

As I sat on the sofa and spread my legs wide to reveal my cunt, Jiyoon licked her lips and began to push her cock into the opening.

Squelch——

"Ngh-hiiiiik!!♡"

Perhaps because my body had become so sensitive, even though only the glans had entered… my back arched like a bow, and I climaxed instantly.

"Aha, Sister, you’ve really become a total female now♡"

"Ugh…♡ Oooooh♡"

"You're doing great. You're so pretty♡"

Jiyoon kissed my cheek and pushed her cock deeper inside.

Squelch, squelch——

"Ogh-heugh!!♡ Oh-it, ohoooooh!!♡ Ngh-he-eut♡"

I felt like I was losing my mind. Thrusting all the way to the womb had its own pleasure, but the slow, steady insertion made me feel every inch of the glans as it parted my vaginal walls, delivering a pleasure that forced me to climax with every single movement.

"Uung♡ Sister, becoming a female isn't a bad thing at all; it's a wonderful thing because you get to be loved by a male's cock…♡"

"Ngh-he-eugh!♡ Ngh-hugh♡ Oh, hoooo♡"

"You don't have to be embarrassed♡"

As Jiyoon whispered those words as if to brainwash me—

Thump——♡

Jiyoon’s glans softly pressed against my womb.

"———᧗ʃᖍ♡♡!?"

I thought the pleasure had been intense enough already, but the moment the glans touched my womb, a pleasure beyond anything I had ever known surged through my brain like a tidal wave. Unable to even speak properly, all I could do was climax over and over again in Jiyoon’s arms.

Twitch! Twiiitch!

My body twisted from the unbearable pleasure. A blissful sensation continued to ripple through my lower abdomen, and my face was contorted in a way I couldn't even imagine. How on earth was I supposed to endure this?

"Sister. Keep your head together♡"

But Jiyoon didn't stop there; she moved her hips slowly, relentlessly pressing her glans against my womb.

"Ahe-eeeek!!♡ Ngh-it, ngh-hoooooh!!♡ Ngh-hugh♡ Khu-ooooooh!!♡"

I guess Jiyoon really is her mother's daughter. Just like her, she knew exactly where to press ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to make me feel good, training my womb to be that of a true female.

"He-eh♡ Sister, your face is so incredibly lewd♡"

"Ogh♡ Ngh-hiiiit♡ Khu-heugh♡ Ah-aaang!!♡"

"I want to make you my and Mom's exclusive onahole♡ I want to get you pregnant so you can't even get married."

Usually, I would have hated the mention of pregnancy, but why did those words sound so sweet right now? Without realizing it, I squeezed my cunt tight around her.

"Hngh♡ Haaaang…♡ Sister, it’s dangerous if you squeeze like that all of a sudden."

"He-et♡ It’s not, ngh♡ that I, ngh-hugh♡ want to do that, he-et♡"

"It’s because your body loves it."

Squelch!

"Haaaaaaak!!♡"

Because Jiyoon kept targeting my womb, I ended up peeing right then and there. But Jiyoon didn't seem to find my urine dirty; instead, she clung to me even tighter, pressing her glans against my womb.

"He-et, he-eeek♡ Jiyoon-ah-hat♡ Now, my womb, stooop!!♡"

"Uung♡ No way♡ Not until I’ve completely trained your womb to be a female's!♡"

"Ngh-hoooooh♡"

If things kept going like this, I was really going to die from the pleasure. Even though I hadn't ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠been given a drop of water, I felt like I was going to perish. Jiyoon didn't give me ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠a moment's rest, pressing and pressing against my womb.

"He-eut, ngh-hiit♡ Haaaak!♡ Khu-hugh♡"

There was no way a female could endure that. As I climaxed repeatedly, unable to keep my wits about me, and squeezed my cunt tight, Jiyoon’s cock began to swell inside me.

"Oooooh!?♡"

"Sister, I think I'm about to cum♡ Since you're my female sister anyway, I'll finish inside you♡"

No. I couldn't let her. If she finished inside me now, I knew I would never be able to go back to how I was before… I couldn't, I couldn't…….

"Inside, fill me up insideee♡"

I didn't care anymore. I didn't care about anything. Right now, I just wanted to be filled with Jiyoon's semen. My beloved sister's cum. I wanted to fill my womb with it♡

"Sister, I'm cumming!♡"

"Yes, ye-es♡ Fill my cunt up, fill it until I'm impregnated, fill it all the way up♡"

As I practically begged her, Jiyoon put her weight into it, thrusting as if to pierce my cervix—

Splurt! Spluuuurt! Splurt, spluuuuurrrrt——!!

She poured her hot, jelly-like semen deep inside me.

"Khu-ooooooooh!?♡♡"

I’m so… happy♡
