The Prisoner's Dilemma 6

Sluuurp. Slurp. Sluuuck...♥ Kissing my succubus sister is incredibly sweet. We bite and suck on each other's lips, pressing them tightly together without a single gap as our tongues entwine. She sweeps her saliva-drenched tongue through every corner of my mouth.

"Mwah...♥ Is my spit tasty...?" The aphrodisiac mixed into her saliva courses through my veins, making my cock throb violently. "Haaah... slurp, your cock is getting even bigger...♥!"

Even when she stays still, her pussy twitches and squiggles, relentlessly stimulating my shaft. Is having hearts appear in their eyes when they get excited another succubus trait? My own face is reflected inside those pink hearts. It seems I'm just as worked up as she is. In my eyes, locked with hers, nothing but raw, primal lust for this female is reflected. Keeping our gaze met, I begin to swing my hips.

Squish, squelch, squish, squelch!♥ "Ahhh...!! Mmff... slurp...♥" Even though she's incredibly busy squeezing her walls and feeding me her spit, she wraps her arms around my neck and gently caresses my ears. A ticklish, goosebump-inducing, yet intensely pleasurable sensation washes over me.

Plump! Plump! With every deep thrust of my cock, she gasps for air and wraps her legs tightly around my waist. Surrendering herself entirely to me, she focuses solely on the overwhelming pleasure radiating from her pussy and her mouth. "Haaahn...♥!! Kiss, kiss me more... slurp."

Her legs wrapped around my waist make it a bit hard to move. Still, pressing our entire bodies flush against each other while fucking feels absolutely incredible. Suck, slurp, suck, slurp! "Oh-goh...!! This position is too deep...♥ My womb is gonna get crushed!!"

Since the only things supporting her weight are her already weakened legs and my cock, it's only natural that she feels a heavy pressure on her womb from my massive shaft burying itself all the way to the root. I pull my lips away from hers and ask, "But you love it when I ram your womb, don't you, Sis?"

Squelch, squelch, squelch! "Oh-gok...!! Don't ask me that... gasp...♥!!!" "Say you love it!" "I love it!! I love it, so please!! Keep stuffing your cock inside me...♥!!" When I threaten to confiscate my cock until she answers, she finally drops her pride and begs honestly for it.

"Get pregnant by the little brother's cock you love so much!" Slap! Slap! Slap! Slap! Slap! Slap! Slap! Slap! "Ughhh...!!! This is it, this is the one! Sis is... gasp...♥ getting pregnant by her little brother's cock!! It's the best everrr♥♥!"

"Ugh... I'm cumming!" "Fill me...♥ Shoot your cum inside your sister's womb!!... slurp, mwah, mwah... Ohhh...♥!!!!" Spurt! Sput-sputter! As expected, cumming while locked in a deep kiss is the absolute best. She seems to love climaxing mid-kiss too, letting out a loud, trembling moan as her legs shake uncontrollably.

The semen erupting from my glans, which is pressed flush against her cervix, violently floods her baby-making room. "Mwah...♥ I can't stop cumming!! Getting hit in the womb... slurp... by my brother's cum... I'm addicted to it!!!"

Eventually, her legs lose all strength, leaving nothing but my cock to support her dangling body. "Ugh... what is up with this pussy?" Her climaxing walls keep begging for more and more cum. Her entire weight sinks down, as if pleading for me to break past her cervix and ram deeper. Squish! Answering her desperate plea, the head of my cock finally wedges its way slightly past her cervix.

"...Oh... Ohhh...!!" Hit by that unimaginable wave of pleasure, she flails her limbs like a drug addict before losing all strength and going completely limp. Gush, gush! Because her cervix is clamping down hard on my glans, the urge to ejaculate surges endlessly. Without holding back, I dump it all directly into her womb. The forcefully spraying semen violently splashes against her delicate baby-making room. Spurt, spurt♥

She doesn't even have the energy to moan, her body merely trembling in aftershocks. For me, cumming anywhere—be it inside her pussy or her mouth—is fine, but she clearly prefers it when I wedge my glans inside her cervix and blast her womb. I try to wait for her vaginal spasms to subside, but they show no signs of stopping, so I simply pull my cock straight out. Sliiiip.

"……!!" I lay Mina, who squirts out another gush of love juice from the sheer sensation of the withdrawal, down on the bed. "……." She lies face down, as still as a corpse. Wondering if I went a bit too far, I look back at Anna. She shakes her head, reassuring me that everything is fine. "I think she just needs to rest for a little bit."

Well, I can just play with Anna until then. "Anna, breasts." As if she had been secretly waiting for this, Anna quickly thrusts her breasts forward. "Wow." This is the first time I've looked at them so openly since I accidentally saw her coming out of the shower a few years ago. Back then, I used to masturbate to the thought of Anna for a solid month.

"They're almost as big as Mother's." "T-thank you." Just as I wanted, Anna doesn't strip completely out of her maid uniform; she merely unbuttons the front to present her breasts. Her incredibly lewd body stands in stark contrast to her submissive demeanor. Being adopted into this house is truly something I must thank God for every single day.

Engraving these heavenly breasts into my mind, I knead them with my hands. These beautiful, massive tits are gorgeous on their own, but they look their absolute best when squished and deformed under my palms. "They're so soft, yet so elastic." They yield softly when I squeeze them, but the moment I let go, they instantly bounce back to their perfect shape. Truly, this is only possible because she's a succubus. "Shape-memory breasts...!" "W-what on earth are you saying...?!" Squeeze, knead.

"Do you produce breast milk too, Anna?" "No..." Anna's face falls at my question. I feel a bit disappointed too. "Except for Mistress, everyone else has to get pregnant first to produce breast milk."

I look up from massaging her breasts, my expression turning curious. "Pregnant?" No matter how much cum I blast inside them, they always absorb it. Was pregnancy even possible? "Mother never said she actually gave birth to my sisters and Mari herself, though?" Squeeze, squeeze.

"Hahn...! Y-yes. Things were incredibly difficult back then. She used up almost all of her stored energy to give birth to them through magic." "Magic?" "Yes. Since succubi are strictly female, and it's extremely difficult to get pregnant without a powerful seed, I heard such magic exists. ...Though, Mistress is the only one capable of casting magic of that caliber."

Suck, suck. Anna strokes my hair as I suckle on her breasts, unable to reply. Feeling her fingers gently running through my hair, I gather both of her nipples together and suck on them vigorously. "Hnghh, y-you can bite them a little...!! I-I don't mind...♥ Ahhn, the absorbed jeonggi is, mmgh, used for magical purposes like that. It's also our primary source of energy, just like food is for humans."

Lick, lick, lick. "P-please flick them more...!" I flick her nipples with ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠my tongue while listening to her explanation. It's a shame she doesn't produce milk; that would have been perfect. "If we don't absorb the semen and just leave it be, fertilization can occur just like in humans. However, given our current situation... we can't afford to do that."

Slurp. I pull my mouth away from her nipple and ask, "Then what if I pump so much cum into you that you can't possibly absorb it all?" At my question, Anna's face lights up with sheer happiness, as if she's just received a marriage proposal. "That is also possible. However, it's practically impossible, and as I mentioned, our current situation doesn't allow for ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it."

"Situation? What situation?" Rub, rub. I slide my hand down to caress Anna's lower abdomen. Once she enters her Succubus Form, a womb tattoo will appear here, right? *Press, press.* Driven by curiosity, I press down firmly with my fingers. "Ohhh...♥! *Ahem*, we have a natural enemy." After letting out a brief, animalistic moan, her face flushes red as she continues her explanation.

"The women of the Cheon Clan. It's a family where only girls are born, specifically destined to counter us succubi." "Really?" Ah. I remember being taught about this. Beware of Cheon Clan women. Back then, I had just nodded without knowing the reason, but now it finally makes sense. *Nod, nod.* Anna nods back, her face completely relaxed as she enjoys my womb massage.

"But Mother said she's going to turn me into an incubus?" "...That is the key." Anna stops there, keeping her mouth shut. I see. So I'm the secret weapon created by the succubi.

It'll probably go down something like that. I fully intend to fulfill whatever duty is thrust upon me. I have to repay the kindness they've shown me, after all. But as it turns out, they aren't throwing me into a bloody battlefield to fight to the death. In the end, they just want me to fuck women, right? I have absolutely no reason to refuse. When I look at Anna with eyes full of determination, she looks back at me with an expression that says I'm her only hope.

"Ughhh...!" Just then, Mina groans from the bed, seemingly regaining consciousness. "This isn't just sex." Letting my cock, which shows no signs of dying down, dangle freely, I walk over to her. "This is for a noble purpose." "Hnghh... let me rest more." "For the sake of our family." "P-please." Grab! I firmly catch Mina as she tries to crawl away.

"And for the sake of my personal harem. You have a duty to sacrifice your pussy, Sis." "N-no! I don't want to get bred like a bitch by my little brother! I'm gonna get addicted...!" She struggles, shaking her hips—which are just as plump and sturdy as her breasts—back and forth. She thinks she's resisting, but rubbing such a lewd ass against my cock is nothing short of seduction.

I decide to teach her that lesson. Pinning her down with my entire body so she can't escape, I slide my cock right back in. I might have joked about shape-memory breasts with Anna, but that's actually a trait ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠shared by all succubi. Even Mina's pussy, which I'm currently ramming, is no exception.

"Oh-gogok...♥ Your c-cock is back again...♥!!" Squish! Squish! No matter how many times I fuck her, the moment my cock slips out, her walls return to their original state. She always retains the tight grip of a virgin pussy. "Mmm-gghhh...♥! I love your cock! I love getting bred so much♥♥!!"

I love the way her plump, bouncy ass cheeks ripple with every thrust of my cock. She was trying so hard to run away before I put it in, but she tames down the instant she's impaled. Releasing my grip on her waist, I begin to knead her butt cheeks. Personally, I'm more of a breast man, but an ass like this is something I could squeeze for the rest of my life. Squeeze, squeeze.

Squish, squelch, squish, squelch!♥ Her pussy is burning hot from the back-to-back sex. Without giving her walls a single second to cool down, I keep pounding away. "Ohhh... your cock is going so deep! It feels so good...♥ Keep stuffing me deeper, ohhh...♥!!" All she has to do is lie obediently on the bed and present her pussy, and she gets a free cock. Plus, a generous serving of cum as a bonus. Where else are you going to find a little brother like me?
