## Chapter 207 – Clear (6)
“…Ugh, hnnng…♡”
“What’s wrong? It’s only been ten minutes, are you already struggling?”
My sister, who was lying on top of me, barely supporting herself with her hands on my chest, was breathing heavily. Her toes were pointed, her legs had been trembling since a while ago, her expression looked somewhat dazed, and a warm, lukewarm liquid was flowing down her crotch, running down my dick.
‘N-No way…? Be quiet and just lie still… Haa…’
She’s been holding a mouthful of semen, enough to make her cheeks bulge, for ten minutes now, clearly struggling. Even though it’s obvious that the composure she had at the start is long gone, she’s pretending like nothing’s wrong.
Honestly, I thought she wouldn’t last five minutes, but she’s barely hanging on.
“…You’re holding up a lot better than I thought.”
‘That sounds like you’re being sarcastic. Just you wait, it’s been fifteen minutes now.’
My sister gives me a slight smile with her stiff lips, gesturing with her eyes to the clock placed by the bedside. In that short time, another five minutes had passed, leaving exactly half of the promised time, fifteen minutes. Has that much time already passed…? It seems I underestimated my sister’s endurance too much.
Well, she’s not Chaeyoon or Sua, she wouldn’t be a woman who can’t even endure this much. Even so, the desire would have been constantly building up because of the mark’s power, so it’s amazing that she’s overcoming it with willpower alone. I guess she really is different from ordinary women.
But I can’t just give in like this, so should I use my hands a little?
‘…Hehe… You’ve gotten quiet? I told you, no taking it back! Even if you beg me now… Ugh…?’
“Why? There wasn’t a rule about not touching, was there?”
‘That’s true, but… what are you doing?’
I carefully placed my hands on my sister’s slender waist, who was confidently laughing at me, sure of her victory. My sister, startled by the sudden touch, looked down at her waist and tilted her head.
Caressing her skin, which had become smooth with sweat, I slowly moved my hands.
‘…I don’t know what you’re thinking, but it doesn’t seem to be very effective? Hehe… Hnnng?!’
“Eunghhh?!♡”
I thoroughly explored my sister’s waist, then placed my hand on one spot, the lower abdomen where the mark was engraved…
Gently pressing on the small uterus beyond it with both thumbs, applying a light stimulation, I heard a moan that combined the voice echoing in my head and the voice ringing from my sister’s throat.
“…Ugh… Oop… H, ugh…♡”
Covering her mouth with both hands to hide the small amount of semen that leaked out and her trembling lips, my sister’s eyes widened as if she was flustered by the unknown pleasure that suddenly pierced through her body.
‘W-What was that just now…’
“How was the uterus massage after all this time? Ah, you wouldn’t remember since you were hypnotized back then.”
‘…Huh? What are you talking about? Massage…?’
I smiled slightly at my sister, who looked like she didn’t understand the meaning of my words, and moved my fingers. I gently kneaded her belly with my thumbs placed on her lower abdomen, with just the right amount of pressure.
“Eunghuuut?!♡ Haa, haaa…!♡ Oop….!♡”
Each time her uterus was massaged through her belly, she pressed her mouth shut with both hands, her slender legs convulsing as she swayed her upper body. A cute sight of her floundering, unable to cope with the unknown pleasure.
‘…What, is this… This warm, pleasant feeling won’t leave my head…♡ Every time my belly is massaged, my mind goes blank… What did you do to this body…’
“What did I do? It’s nothing much, I just played with that body a bit before you got it. I always hypnotized her before she went to sleep and slowly massaged and tormented her with care… Now, just a little pressure is enough to make this body drip with juice.”
‘Ah, wait…! Don’t massage while you’re talking… Oop…!♡’
Like squeezing toothpaste, her pussy spurted honey every time I pressed on her uterus. It was the result of playing with her uterus every night before Lapus took over this sister’s body.
Now, if I just keep massaging her steadily like this…
“Ugh, eunghueeeeughugh?! Ugh, ugh… H, oop…….♡”
I had finished developing her into a body that could easily go limp and tremble like this. Of course, it seems she didn’t remember because it was training I did while she was hypnotized.
‘…You… That’s cheating….♡’
“Cheating? I never said I wouldn’t touch your body.”
‘Ah, wait…! I just came, so stop with the uterus…!’
“Eunghyuuut…!♡ Oop, th-that…!♡ Oop…”
My sister’s eyes glazed over at the uterus orgasm she was experiencing for the first time while conscious. Just as the afterglow hadn’t completely faded, I put strength into my fingers again. The glans, which had been in contact with her skin, was now completely soaked in the honey she had spurted out, shining with a glossy sheen under the light, and my sister desperately straightened her back.
As I moved my fingers without rest, I glanced at the clock by the bedside, and ten minutes had passed. Now there were only five minutes left until the promise. The mark’s effect would disappear in five minutes.
Perhaps aware that there wasn’t much time left, my fingers unconsciously sped up. I rubbed, pressed, and massaged my sister’s snow-white skin until it turned red.
“Keueup…!♡ Oot…! Haa…. Ugh…?”
My sister also seemed to know that there wasn’t much time left, and she clenched her teeth. The moment she straightened her back, putting strength into her heels to endure, something happened.
My sister’s body, which had been shaking with pleasure tickling her insides, arched back greatly, and she instinctively released the strength in her heels and raised her toes to regain her balance. But thanks to that, the balance of her body, which she had barely maintained, collapsed in an instant…
Thud.
With that squelching yet somewhat dull sound, my glans was inserted. My sister’s inside was narrow and hot. I had only inserted my glans, but it felt like her vaginal muscles were alive, intertwining and welcoming me.
Yes, I had only inserted my glans.
“….Oh…. Ooot…. H… Ook…….?♡”
My sister’s hand, which had been covering her mouth, limply fell, and a tide of fluid gushed out from her pussy. Her pupils were turned upwards, revealing more of the whites of her eyes, and she was drooling the semen she had been holding in her mouth.
“…Sister? Are you okay?”
“….Hook…. O…. Ugh….♡”
There was no answer to my question. The voice I had been hearing in my head also stopped, and my sister collapsed to her knees. Thanks to that, the tip of my dick was inserted much deeper than before, touching something soft that made me flinch.
“….Euhot?!♡ Geueubeuep…?!♡ Ah, coming….♡”
For a moment, my sister’s lower body convulsed greatly, and after sticking out her tongue and making an animalistic moan, she slumped down on top of me like a doll with its strings cut.
…Did she faint…? I don’t think I did anything that severe yet….
I took my hands off my sister’s small waist, who had lost consciousness while sitting, and after sitting her on my lap, I looked at the clock. What happens in this case? Is this a draw? First of all, the time is…
Thirty minutes had passed. The promised time had already passed a long time ago. Because my sister lost consciousness, it was ambiguous which side had won.
“…Then the mark is… Huh?”
I slightly tilted my sister’s shoulder and looked at the mark, which I thought would have disappeared. But it hadn’t disappeared, and the red mark was burning brightly. I didn’t know what was going on…
“…It’s complete?”
The condition for the mark to be completed was for my sister to ‘admit defeat on her own.’ In the end, the condition would have been for her to swear to become mine, unable to overcome her desires.
…..
No matter how much I thought about it, I didn’t know what was going on. The only possibility that came to mind was….
“…Eunghet, ah…♡”
I looked down at my sister, who was still tightening her pussy even in her unconscious state.
“…Other than the fact that my sister had feelings for me from the start…”
My sister’s heart was already mine, and the reason the mark was completed now was because my sister had ‘lost.’ She had fainted on her opponent without even finishing the bet, so if you think about it, it was my sister’s ‘defeat.’ And if my sister had feelings for me from the start, even before this bet started….
It all makes sense.
“….”
I felt a strange tickling sensation again, so I raised my head and looked at the ceiling for no reason, then lowered my head again and hugged the small body in my arms, who was unconscious and moaning. As if that small body had been wanting me all along, it wrapped around my entire dick, and her uterus, which had reached the limit of its endurance, clung to my glans like a leech.
“…Sister…”
My last memory was of something hot rising to the top of my head, and after that, the only fragmented memory I had was of thrusting my hips into my sister’s unconscious body.
………
………
………
“…..Ah….”
“…Haa, uh…. Sister, are you awake?”
“…The inside of my stomach is so hot….”
“Ah, I’m sorry…”
I don’t remember how many times we did it after that, but the sunlight that could be seen through the curtains was already setting.
My sister, who had finally regained consciousness, opened her eyes with a face messed up with tears and saliva, and raised her hand, which was trembling because she couldn’t put any strength into it, and pushed my chest away. It wasn’t a very strong force, but I slowly pulled my body back and pulled out my dick.
“…Ugh….♡”
Following the dick that was pulled out with a sticky sound, a white fluid came out a beat later. The semen that came out of my sister’s inside poured onto the bed, creating a small puddle, and my sister’s lower abdomen, which had been slightly swollen, gradually shrank.
“…You came a lot… Treating a woman who’s not even conscious like this… Pervert…”
“…I’m sorry.”
My sister reached out her hand to her pussy and scraped together the semen that was leaking out with her fingers, brought it in front of her eyes, and stared blankly at the sticky semen stretching out. A somewhat quiet atmosphere. Both my sister and I were just sitting quietly, looking at each other.
“…So much of this thick stuff…”
“……”
“Hehe… It’s okay. I asked you to do it today, so I felt good too… Ah, I’m hungry. Aren’t you hungry? I want to eat meat, let’s go eat.”
My sister took the semen on her hand and licked it off, then got up. The sight of my sister heading to the bathroom to wash off the semen that was constantly dripping from her crotch, smiling at me. A somewhat easygoing atmosphere than usual…
“…Okay, then I’ll buy you pork belly and soju today, so take your time washing up…”
“Ah, no soju. I have to abstain from alcohol now.”
“….Huh?”
Just before entering the bathroom, I ran sister, who was stroking her belly and blushing.
“….Wait, Sister, that…”
“Ah, really. You should just pretend you don’t know in situations like this. It’s all because of someone that I can’t even leave anymore~”
