Elise and I had been at it for about two hours now. Our activities mainly revolved around blowjobs, hand jobs, and mutual masturbations, but we hadn't crossed the line into full-on sex yet. It just didn't feel like the right time.
"Mmm... Ahh... lick Such a strong taste... slurp Ahh... Mmmm... Mmm..."
Currently, we found ourselves in a sixty-nine position, pleasuring each other. I could feel Elise's hot breath on my still-raging boner, which hadn't subsided even though I had ejaculated four times by now. She abruptly stopped licking and slowly took it into her warm mouth, her tongue welcoming it.
As she lowered her head, I felt her two melons pressed against my stomach, accompanied by her two erect nipples teasingly poking me. Her swaying, sexy, and plump ass in front of me seemed to be playfully tempting me to engage with it. In response to her taking my cock in her mouth, I reciprocated. I started by spreading her pussy wide open, gazing at it in the hope of finding a barrier, but unfortunately, there was none. As I suspected, she was no longer a virgin.
But honestly, that didn't matter, did it?
I decided to assert my dominance over her, making her think only about me and ensuring she wouldn't engage in sex with anyone but me. It surprised me, realizing how possessive I could be, even with my own blood and flesh sister.
With my determination to make her mine strengthening, I extended my tongue and gently caressed her soft pink flesh.
"Mmmmm... Ah... Mmm."
Elise slightly jumped in surprise as she felt my tongue on her pussy. It was sweet and lightly tangy, a delicious taste, to say the least.
"Ahh... Y-Your tongue is so lively. That's it... Lick me more... ahh..."
Every time I licked her, I could feel her seductive body quiver on top of me. Elise bobbed her head up and down, using her lips to squeeze at me. The experience was truly intoxicating, and I couldn't help but worry that I might get addicted to her. Our rhythm became more synchronized, and we used our tongues to push each other towards the peak of ecstasy. I gripped her firm and sizable ass harder, pushing my tongue deeper into her delicious slit.
"Mmmmmmmm!! S-Something is about to come soon! Mmm! Mmmn! Mhh! Mmm!!"
I intensified my licks, encouraging her impending climax. I wanted my sister to cum. I craved for this sensual sister of mine to reach the peak of pleasure. I wanted to claim her as mine, wholly and exclusively. No other men would be allowed to touch her. She is my sister, and I would never permit anyone else to have her. I was ready to go to extreme lengths to have her.
As I tasted more of her delicious juices, a sign that a dam was about to burst, I couldn't contain my desire.
I paused my licking to say, "Let's cum together, Elise."
Elise didn't cease her movements. She sucked my dick even harder, as if attempting to drain me using my dick as her personal straw. Her mouth tightened, clamping down firmly on my cock.
And then, suddenly, I felt a rush of pleasure spread through my whole body. For a moment, I held it back, wanting to synchronize our climaxes and make her cum together with me. I licked her powerfully.
"I'm cumming too~! Mmmmmmph! Mmmmmn!!"
Elise's body slightly quivered with my cock in her mouth, and a huge squirt shot out of her urethra. I found myself covered in her lewd smell. Simultaneously, my thick, cloudy semen erupted from my dick, filling her mouth to the brim. The overflow puffed around her lips, reaching a point where containment seemed impossible. Undeterred, she forced herself to drink it all in one voracious gulp.
After the satisfying gulp, she released my cock, a thread of saliva still connected from the head of my dick to her glistening lips.
"Hehehe... I made you feel good, didn't I? You came so much that you can't deny I made you feel good, right?"
I took a peek and saw her erotic face covered with my white semen. Some had splattered all over her face, but she didn't seem to mind. In fact, she appeared to love it.
"Yeah. That really felt good," I breathed out.
Elise began to lick my dick again, cleaning off the semen from all of it. She sucked it all into her mouth and swallowed, as if savoring a delicious white sauce found in a French cuisine.
"I cleaned it for you. Hehehe."
I couldn't help but feel jealous that some random man might have seen this beautiful lewd face before. However, I forced the jealousy down. Such feelings were normal, but they weren't important right now.
While casting my gaze once more upon her enticing pussy, a peculiar sight caught my attention. A purple glow emanated near her crotch, forcing me to squint my eyes to shield them from the potentially blinding light. After a fleeting moment, the radiance subsided, revealing a small pink heart tattoo just above her crotch. It was a motif frequently seen in hentai, particularly when the girl in question was a succubus. Could this mean Elise was a succubus herself? And what about me? Did I have succubus blood too?
As I contemplated these thoughts, Elise fixed her gaze on me, her pupils now shaped like hearts. She licked her lips in a lewd manner and then positioned herself so that her head was aligned with mine. Straddling me, she spoke with a bright, lewd grin on her face.
"Ahh~ I want to fuck!" she exclaimed with an unapologetically lewd grin. "I want to fuck you, brother. I want to drain you dry!"
My mind raced, trying to comprehend the surreal turn of events. As she seized my throbbing dick, ready to forcefully introduce it into her awaiting pussy, my Guardian skill, copied from Gabrielle, abruptly surged to life. It acted as an unseen force, forcibly pushing Elise away from me.
"Kyaah!"
I had no clue why the Guardian skill had intervened, but I knew its purpose – to protect me from potential harm or death. Did this mean Elise was trying to kill me?
"You're resisting, I see," she declared, regaining her balance with a seductive grin on her face. "Don't you want to fuck your sister, too, Leon? I've yearned for you to fuck me. Can you fathom how long I've awaited this moment?"
My mind raced, struggling to comprehend the bizarre situation. With caution in my eyes, I stood up from the bed, creating a slow but deliberate distance between us. The atmosphere crackled with an unpredictable tension, and I felt a surge of adrenaline.
"I don't know what you're talking about, Elise, but for now, just calm down." My voice carried a blend of confusion and concern. I needed to tread carefully until I could make sense of this strange episode.
"I can't calm down. Not until you fuck me!" With a desperate leap, she lunged toward me, hand outstretched. In a nimble maneuver, I skillfully dodged her advances.
After that, she sprung at me once more, a desperate, lustful gleam in her eyes. My nimble evasion only seemed to fuel her ardor. The air crackled with a charged tension as she exhibited a demeanor reminiscent of a wild creature in heat.
"Why are you dodging?!"
"You're scaring me, you know."
"Don't be scared. I promise your big sister will take very, very good care of you!"
I maintained a cautious distance, studying Elise's unpredictable behavior. Her eyes radiated an unsettling desire, transforming the atmosphere into an intense blend of curiosity and unease.
"I don't know what's gotten into you, Elise, but this isn't normal," I said, my voice laden with genuine concern.
She pouted, attempting an innocent facade amidst the lewd aura enveloping her. "But I just want to have some fun with my dear brother. Why are you being so mean?"
"As much as I would love to as well, I don't know what will happen to me if we did."
That's right. The Guardian skill was warning me that if I fucked Elise, I would be put in harm's way. I had no idea what that harm entailed, so I exercised caution. Dying prematurely wasn't part of my plan; there were still things I wanted to accomplish.
If my assumptions weren't off the mark, Elise might indeed be a succubus. Engaging in intercourse with her could lead to the draining of my soul or something equally ominous. I'd seen enough hentai to recognize where this could be heading...
I couldn't allow that to happen.
Swiftly, I darted behind Elise, her lewd smile still lingering, and delivered a precise hand chop to the nape of her neck. Almost instantly, she slumped into unconsciousness, and I caught her before she hit the ground.
Lifting her in a princess carry, I noticed that the tattoo above her crotch had vanished. Could that have been the reason for her berserk behavior? For now, I decided to lay her down on the bed.
Carefully placing Elise on the bed, I observed her peaceful slumber. She looked pretty cute, lying there so peacefully. Having never had a big or little sister in my previous world, this was a new experience for me. However, I wasn't sure how to act like a brother, especially considering I might not have been her brother all along. I was a reincarnation, just awakened in this body, and who knows if this body truly belonged to me?
Opening my quest panel, I saw:
--
2. Allow Elise to perform sisterly deeds on you 10 times (4/10)
--
The count had increased by two. I had no idea when she performed sisterly deeds for me. Well, if we considered pleasuring me, I supposed she did. I shrugged it off and looked at her peacefully slumbering. Her bare breasts gently rose and fell with each serene breath. After a while, she stirred, opening her eyes to gaze at the ceiling momentarily. When her eyes met mine, a subtle tension filled the air, replaced by a fleeting twinge of fear in her gaze.
