    It was Sunday, thest day of the second week since my OnaAka possession began. I browsed through my stats with a sense of finality. Having started from the very bottom at Level 1 with a mere 5 stat points, my growth had been tremendous, especially considering the various cheat powers I had gained along the way.


    I could already say that I was on an entirely different pathpared to the (former) Sang-hyuk.


    The environment around me had be as soft and pliable as Henna''s breasts, and I had grown somewhat ustomed to living as the protagonist of this erotic game. But I couldn''t help but wonder: would the game end once I''d "devoured" them all?


    I had to consider the lengthy tale that would unfold from here on out.


    As I was sessfully expanding my harem, I needed to amass wealth and power to create a safe environment where my women could be pregnant without worry. Thankfully, OnaAka provided clear guidelines for this aspect.


    I became an "Onahole collector." The encyclopedia bonus linked to my four primary stats was applied separately, not added to the stats themselves. In this world, the ability to receive a high stat bonus merely by collecting onaholes was a tremendous advantage.


    The collection effect of [Special Grade Mother''s] was quite beneficial. It was great that I could be stronger just by having sex. If I were to take a more proactive approach, I could deal with the rare magical beasts lurking deep within dungeons, simultaneously gaining collection effects and exchanging them for substantial amounts of coins from the demon merchant.


    ''Hmm. I''m doing well.''


    The academy was the perfect ce to pursue both my harem and personal growth. I couldn''t help but smile while looking at my 『Student ID," Kim Sang-hyuk』.


    "Oppa."


    Knock knock. Serena politely knocks on the door.


    "It''s not breakfast, but I prepared a meal in case you were hungry. Do you want some?"


    If I eat now, it''s a little early for lunch. Good. Last week, I couldn''t spend time with my sisters because I was having sex all day at Henna''s house. I tried to stay at home for just one day today, but something good has already happened.


    It''s Serena''s home-cooked meal. When I opened the door and came out, my beautiful, raven-haired sister looked up at me and smiled. Behind Serena''s innocent sisterly facade, there is a sultry side that finds it natural to wear provocative lingerie and openly disy her panties for her brother''s pleasure. It was utterly adorable to see her wearing an apron now.


    "What''s on the menu?"


    "What''s left of the lunchbox? Beef and radish soup, egg rolls, and seasoned spinach"


    "Oh, eel…"


    It was the work of Grania, the inn''s hostess. Probably? That''s good, too.


    "Is there any chili japchae left?"


    "Oh, yes, I made it!"


    "…How? Did we have a mental connection?"


    Serena said, blushing slightly.


    "My brother seemed eager to use his chopsticks again. I was getting ready to make more."


    "...."


    I feel embarrassed, too.


    My menu preferences were being detected. And his attentiveness in making the dishes I like.


    Serena will definitely be a wonderful wife.


    "Can I touch your breasts, Serena?"


    "Yes?"


    Serena quickly turns around.


    I immediately caressed Serena''s breasts and rubbed my cock against her buttocks.


    Ah, I love grinding on my little sister''s curves.


    I also sucked on her nape.


    "Hmm? Did you spray something on your neck?"


    "Just a little... Ah, because you often sniff there."


    "No, Serena. Your natural scent is better than perfume."


    "...Heh...."


    Fondle? Fondle?


    Serena''s bountiful bosom is simply the best…


    We were having passionate sex just a while ago, and now my balls are on fire.


    I know I shouldn''t be doing this to my sister, but I...


    Rubbing… .


    "Ha… uh… the food will get cold. Is that okay?"


    "Ah. No, that''s not good."


    She took the time to prepare such a delicious meal.


    Atst, I firmly pinched Serena''s nipple between my thumb and index finger, tugging it with force.


    "Ah…?"


    After bringing Serena to climax through her nipple, I headed downstairs.


    "I used up so much energy; I need to eat some eel."


    "Did you go on a date with your girlfriend?"


    "Yeah."


    Ste, who had been watching TV, joined me at the table and naturally took the seat beside me.


    "A senior with ck hair andrge breasts? Or… a senior with long brown hair and a pretty face?"


    "Isn''t the ck-haired, well-endowed person Serena?"


    Ste chimed in.


    "That''s right."


    Both of them had impressively ample busts.


    "But you can''t really go on a date with your sister."


    "We could… hmph…."


    "Big brother, there''s now saying families can''t go on dates, right?"


    Is that so? I suppose watching a movie and having a meal together wouldn''t be too difficult.


    "I feel most at ease when I''m at home with the two of you like this."


    It''s because we''re family. Being together at home is the best…


    "I also enjoy being at home with you…"


    Serena bashfully agrees. Ste, without admitting any embarrassment, skillfully maniptes her chopsticks.


    "Me too."


    She then adds a whisper.


    Ah, Serena''s spicy japchae is delicious… The beef and radish soup is incredibly refreshing. Even after being possessed by the OnaAka, despite everything bing profane, the act of eating remained unchanged. I scoop a heaping spoonful of white rice, stuffing it into my mouth,dle the soup, and pick up side dishes with my chopsticks.


    There''s something profoundly moving in this simple act. The fact that my voluptuous and beautiful sister takes care of my meals only intensifies the sentiment.


    "I''ll serve you some soup, big brother."


    Serena swiftly takes my soup bowl.


    In the meantime, something brushes against my leg, and I discover it''s Ste.


    Ste entwines her leg with mine, her foot toying with my calf.


    Her bare toes wriggle as they graze the top of my foot. I never understood why couples on TV would be inmed by such a simple act, but experiencing it firsthand, I feel as if lightning has struck my cock. Blood rushes in.


    "Big brother…"


    "…"


    Ste elicited a reaction from her brother using her feet and murmured in a sultry voice,


    "About yesterday… Should we continue in your room?"


    "Continue…?"


    Is she going to pleasure me again? My ears perk up.


    No, I can''t let myself be enticed. What am I thinking?


    It was only yesterday when I tried to cross the line and she pushed me away.


    What kind of change of heart is this?


    Does she want to engage in erotic acts with me again?


    My mind bes a whirlwind of confusion.


    "Mm-hmm…"


    Gasp!


    Ste''s feet glide against mine. Her bare thighs, revealed beneath her frequently worn dolphin shorts, appear so supple that it''s driving me mad.


    Her delicate ankles and lovely feet effortlessly dance over my instep.


    "Is it…not possible?"


    Just then, Serena naturally stepped in between us.


    "Here, your soup."


    "Thank you…"


    "Ste, do you want another bowl?"


    "No… I''m good."


    …Huh? A peculiar tension lingers between the two.


    Did something happen while I wasn''t here?


    Serena maintains her usual gentle demeanor, but Ste is tantly on edge, her eyes narrowed in abative stance.


    After mealtime, I approach Serena from behind as she tidies up the dishes and ask,


    "Serena, what happened with Ste?"


    Rubbing gently, Serena calmly replies while pressing her rear against me,


    "Mm~? No, it''s just that we both like you so much… We want you to pay more attention to us."


    "Hmm…"


    Swoosh. Swoosh.


    While Serena washes the dishes, I cling to her and fondle her breasts.


    "Big brother, are you touching your little sister''s breasts as if it''s natural now?"


    "Ah!"


    "Did you really decide to be a perverted brother?"


    "I suppose…"


    I can''t criticize Serena, who buys erotic lingerie.


    At this rate, I''mpletely a perverted big brother.


    "But… it''s Serena''s ass…"


    "Sigh, I guess I can''t help it…?"


    As if epting my regressed intelligence, Serena presses her rear even closer.


    Oh, the healing power of her ample behind…


    Embracing the weekend, I indulge in Serena''s breasts.


    Engaging in risqué skinship with my little sisters has be somewhat of a routine.


    Just like yesterday''s oral service.


    While watching TV, Ste saunters over and takes a seat beside me. She isn''t attempting to brazenly suck my cock in front of Serena, but…


    "Knee pillow. Big brother."


    For rification, Ste isn''t offering to provide a knee pillow for me. Instead, she intends to lie down and requests the use of my leg.


    "Alright."


    Ste unabashedly uses my cock as a pillow, rubbing her lovely face against it. After searching for afortable position for a while, she watches TV while resting her head on my cock. Feeling the warmth emanating from the back of Ste''s head, my cock continues to harden…


    "…Heh…"


    Ste steals a nce at me, wearing a satisfied grin. It''s the sort of devilish smile that says, ''I''ve taken control of my big brother''s erection.'' That was the moment I realized that evenzing around at home on the weekend is no easy task with OnaAka.


    "If I do it now, I can suck Serena off without her noticing."


    "Hm? What''s that, Ste?"


    Serena enters the scene. Dressed in hot pants like Ste, she takes a seat next to me. Oh, boy…


    My body responded to the overwhelming size and curvature of Serena''s voluptuous breasts and hips. Serena sat down next to me, offering herself to be my "kissing pet."


    "Oppa, want to y chu-chu?"


    "…"


    I couldn''t resist and found myself kissing Serena as if possessed. With one hand, I reached out, caressing her breast while our tongues intertwined. Damn it… I shouldn''t be passionately kissing my sister like this… But I couldn''t help it when I touched her soft, warm breast while we kissed.


    "Ah~"


    As if inviting me to indulge in her mouth, Serena opened her lips and offered her tongue. I lost myself in the moment, hungrily sucking on her tongue.


    "Chu… chu… chup… chup…"


    When I finally came to my senses, Ste had taken Serena''s ce, sitting across from me. She wrapped her beautiful legs around my waist, anchoring me in ce, and tried to steal my lips for herself.


    "Oppa… it''s my turn now…"


    "Chu… chu… chup…"


    Ste was aggressive. As my mouth opened, she clung to me, eager to im every drop of my saliva as her own. Our lips met, sucking and slurping upon one another, and I felt as if my cock would burst from the intensity.


    "What is this…?"


    How can I endure this…?


    Even if I bear some responsibility for extending my cock to be rubbed, or attempting to touch my sister''s breasts.


    Even with that in mind… The affectionate expressions of the two younger sisters who love me… I was on the brink of losing my self-control.


    "Brother, let''s watch TV… guys."


    A passive defensive stance.


    Ste, as if it didn''t matter, wrapped her legs around me in a loving embrace, pressed her lips against mine, and passionately sucked on them.


    Ah, a delightful fragrance wafts from Ste''s nape…


    Even while kissing Ste, Serena stood beside me, her hands interlocked,


    ying with my hand.


    This can''t be…


    Our home has turned into a den of shameless younger sister pregnancy sex…!!


    Ste asked me while we exchanged affectionate pecks.


    "Big brother, what if… just what if? If you had to do it with one of us, who would you choose?"


    "…"


    "…"


    The atmosphere turned icy…
