A Breast Milk Party Overflowing with Family Love

The skill’s effect was as brutally straightforward as its name suggested. Once cast, it opened the door for lines like, “A woman who isn’t even pregnant is producing this much milk?” On top of that, it boosted Strength and Agility by two points each. Just as the saying went, children raised on breast milk grew up strong. Still, the part that nagged at me was why only men who drank it took a two-point hit to their Charm. Was the system trying to say it disapproved of men drinking breast milk?

Damn it, what was so wrong with a grown man enjoying a woman’s milk? Did a guy in his mid-twenties, stubble already shadowing his jaw, have no right to cry “Wah, mommy!” while indulging in breast-milk play? …No, on second thought, maybe the penalty made sense.

Even so, a measly two-point Charm loss was worth less than trash on the roadside compared to the pleasure of a proper breast-milk session, so I decided to ignore it. Focusing on the skill window helped cool the excitement that had been boiling inside me after impregnating my little sister. Only then did the other people in the room register again.

When I turned my head, I saw Emilia sitting in a chair with her legs twisted together, frantically masturbating. The seat beneath her ass was utterly drenched; her juices had already spilled over the edge and were dripping down the chair legs onto the floor. The front of her robe clung obscenely to the shape of her pussy as she asked in a voice thick with moans.

“Haung♡ Is everything finished now, Arwen?”

“Not yet.”

“Hmm, is that so?”

Emilia pouted, lips pushed out cutely. Leaving the professor—who was making those incomprehensible lewd sounds—behind for now, I first pulled up the quest window.

The holographic window floating before my eyes showed that the quest timer and conditions had updated. The zero beside the “Impregnate Cordelia” objective had been replaced by a glowing 1. The skill I’d been half-suspicious of had performed its role perfectly. As expected, there was no need to doubt the System.

My seed, carrying my genes, had successfully taken root inside Cordelia’s womb. Fuck… my heart’s all over the place now.

Looking at Cordelia lying on the bed through the translucent quest window finally made it feel real. Even when I’d promised Raibel I would give her a child, even when I’d declared I would make Cordelia give birth to my niece or nephew, it hadn’t sunk in. But now, in less than a year, I was going to become a father—one father, or maybe more than one.

I had always thought marriage and childbirth were distant future events that had nothing to do with me. I never imagined the chance to build a family would arrive so suddenly. Then again, after being sucked into this game and pumping out ridiculous amounts of cum everywhere, it would have been stranger if this day never came. I had simply tried not to think about it.

No. Don’t get scared before you even start, you pervert. Is raising a kid really that big a deal?

Suddenly, memories of my own childhood surfaced. The days when I sold porn and adult games to other kids, taught my friends how to jerk off, and got dragged in front of their parents were just everyday life. What if my own child ended up doing the same thing?

Yeah… it really is a big deal, fuck…

I didn’t know what hardships lay ahead, but I was sure I could overcome them. Especially if I had the precious women who stood by my side right now. Still, surviving came first if I wanted to find out exactly what those hardships would be. And to survive, I had to clear this quest.

If this had been a normal game, I could have just save-loaded to before I gained the Short-Lived trait, but unfortunately the System didn’t allow that. Thankfully, only one step remained before the quest was complete, and there was still plenty of time.

Just in case, I pulled out the mana potion I had hidden under the bed. Savoring the bitter blue liquid as it slid down my tongue, I looked at Sophia. The moment our eyes met, her shoulders twitched. She covered her breasts and took a step back.

“What? Weren’t you satisfied already?”

Her gaze darted back and forth between me and Cordelia like the second hand of a broken clock. I asked the clearly anxious Sophia,

“Didn’t seeing Cordelia like that stir anything in you?”

“Kgh… Th-that’s impossible. Let’s hurry back to the academy. If people notice we both disappeared at the same time, they’ll definitely think something’s strange—especially Leopold.”

The usual calm Sophia was gone. In a fluster she tried to gather the clothes scattered across the floor. It was a shame. Even after watching the passionate, love-filled sex between Cordelia and me, nothing seemed to have touched her heart. But I couldn’t just let her leave comfortably. My life was on the line, after all.

The one who stopped Sophia as she tried to leave the room wasn’t me—it was Cordelia. She sat up in bed and called out to her sister.

“Are you really okay with this, Sister?”

“Okay with what?”

Sophia froze with one leg already in her pants and looked back at Cordelia. The younger sister gave her a mischievous, irritating little smile and said,

“Hehe. If you leave now, the child born from my belly will become the next head of the Reinhardt family, you know?”

Cordelia gently stroked her own stomach with an expression full of love. The older sister, whose complex about the heir position had been perfectly prodded, was left speechless.

“What? Don’t joke around!”

“If you don’t like it, just have Brother’s baby too. Why are you getting so angry?”

Cordelia pouted, then flicked a dried flake of semen from under her nail so it landed at Sophia’s feet. If I had been in Sophia’s position, I would have exploded. It was a perfect provocation. That kind of talent had to be innate; it couldn’t be taught.

While Sophia fumed, I walked behind Cordelia, wrapped my arms around her waist, and rested my chin on her shoulder with a tender expression.

“Don’t push Sophia too hard. She just doesn’t understand the beauty of family love yet.”

Sophia looked like she wanted to scream, “The only person here ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠who doesn’t understand the meaning of family love is you!” but I ignored her cleanly. Cordelia even clapped her hands and chimed in.

“Then there’s no choice. As family, shouldn’t we teach Sister what true love is, Brother?”

“As expected of Cordelia. We really are on the same wavelength.”

“Y-you two… what the hell are you planning?”

We slowly approached the naked younger sister who was looking at us with fear in her eyes. Sophia couldn’t even run; she just mumbled, “Don’t come near me!”

“One day you’ll thank us, Sister.”

“She’s right, Cordelia.”

We grabbed Sophia as she struggled and begged us to let go, then dragged her back to the bed. Normally Sophia could have shaken off two grown men, but right now her legs trembled like a newborn calf and she was pulled along helplessly. The aftershocks of her first creampie still lingered in her lower body. It made sense; it must have been the greatest stimulation of her life.

In the end, Sophia was hauled back onto the bed and held in my arms with both wrists pinned behind her. When Cordelia tried to spread her sister’s legs, Sophia cried out in panic.

“Don’t, Cordelia! What do you think you’re doing?”

“Don’t be so scared, Sister. I’ll loosen you up myself.”

Cordelia gave the shouting Sophia a gentle smile, then buried her face between her slightly parted folds. The same tongue that had earlier coiled around her brother’s glans now rolled over her older sister’s swollen clit. If anyone ever asked for the best example of depravity, this tongue would be it. It was depravity given human form.

Sophia, violated by her own little sister’s tongue, let out a despairing moan.

“Hiiik?! Stop it right now, Cordelia! Doing this with another woman… and we’re sisters! Haauung♡”

Cordelia, still eagerly sucking on her sister’s pussy without even catching her breath, answered,

“Haa… You say stop, but your pussy is absolutely flooded, Sister.”

“Kgh, that’s because you’re doing weird things…”

“I’d appreciate it if you called it an expression of familial affection instead of ‘weird things.’”

Cordelia lowered her head again. Her tongue, now glistening with saliva, licked and sucked every inch of Sophia’s folds. Sophia tried to push her persistent little sister away, but Cordelia dodged nimbly and continued pleasuring her.

“I can’t let my little sister steal my little sister from me when I’m the older brother.”

“Haah♡ Why are you touching me there all of a sudden?!”

I sucked on the earlobe of the Sophia in my arms while sliding a hand up to her breasts. I kneaded the soft mounds and savored the cool temperature of her earlobes, which remained chilly even after such intense sex. Thanks to the heated air in the room, it felt like I was rolling a cold stone across my tongue and swallowing greedily. Pure bliss.

Overwhelmed by pleasure from both above and below, Sophia eventually stopped resisting. She trembled quietly and accepted the caresses from her brother and sister. When the wet sounds from her hole reached their peak, Cordelia finally lifted her face from Sophia’s pussy.

“Puha. I think she’s ready now, Brother?”

“Good work, Cordelia.”

I gave her a thumbs-up, then switched positions with her. Sophia, who had been lying there in a daze, seemed to realize what I was about to do, but it was already too late.

“Haa, haa… N-no, if you put it in now… Hiiiiiik♡?!”

This was only our second time, yet her powerful tightening still felt unfamiliar. Sophia’s strong vaginal muscles—matching her physical strength—clenched around my cock like a hungry mouth. Cordelia, now aiming for her sister’s nipples, spoke.

“Instead of just saying no, why don’t you honestly admit it feels good, Sister?”

Watching my little sister suck on Sophia’s nipples, I activated the Breast Milk Secreting Semen skill. That was why I had downed the mana potion earlier. Little-sister breast-milk play? There was no way I could pass that up.

I thrust my hips hard, rubbing my cock against her inner walls. The anticipation of soon drinking my little sister’s milk made my climax arrive quickly. Hot semen flooded Sophia’s depths, and before long a miracle occurred.

Cordelia, who had been sucking Sophia’s nipple with intense focus, pulled back with a strange look on her face. A thick white liquid with a faint yellowish tint glistened on her lips. Sophia’s nipples began spraying milk like a dairy cow fitted with a milking machine. The rich, sweet-scented fluid flowed down her breasts and onto the sheets.

A virgin whose breasts were leaking milk—it was such an astonishing sight that I felt I could cum from looking at it alone. My urethra wept tears of emotion at a view more beautiful than any waterfall in the world. Naturally, Sophia’s own face twisted in horror as she stared at the female milk gushing from her own chest. Even the Virgin Mary’s expression upon learning she had conceived Jesus could not have compared to Sophia’s right now.

“Kyaaaaak?! What is this?! My breasts…!”

I spoke to the screaming Sophia in a calm voice.

“The Goddess Elysia must have been moved by our loving family bond and bestowed a blessing upon your breasts, Sophia.”

“Don’t joke around! There’s no way that could happen! What did you do to me?!”

While Sophia grew furious at my nonsensical explanation, Cordelia swallowed the liquid in her mouth. She licked her lips and said,

“So this is breast milk… It tastes ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠better than I expected. Can I have some more? I want to get used to the sensation of breastfeeding for when the baby is born.”

Even in this absurd situation where milk was flowing from her older sister’s breasts, Cordelia showed no sign of panic. I nodded at my incredible little sister who was asking if she could suck on her sister’s nipples again.

“No worries. There are two nipples, after all.”

“Thank you, Brother. Then I’ll borrow your breasts for a bit, Sister.”

“N-nooo!”

Together with Cordelia’s cry, I latched onto Sophia’s chest. In the end, Sophia’s left breast was claimed by her older brother and her right by her little sister. The moment I took her already flushed nipple into my mouth, Sophia’s milk poured onto my tongue. The distinctive milky scent ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠filled my entire mouth.

Sophia, forcibly turned into a family-exclusive milk factory, panted.

“Huuuuk♡ Don’t ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠suck… My breasts feel so strange now♡”

But even her tearful cries could not stop the harmonious brother-sister breast-milk party. It continued on.
