NepGear's Onii-chan

Forgive me, but I have sinned. I had soiled my ‘sister’s’ purity. No wait; it was the other way around.

I had fought alongside Nepgear, Compa, IF, Uni and the rest of the party to take down ASIC. Being the only male in the party, it got hectic with sleeping arrangements and walking in on them naked by mistake. I’ve gotten close to Nepgear as I bunked with her a few times in the beginning of the adventure.  It started out as friendship, then one day, Nepgear had said something.

“May I call you… Onii-chan?”

Let me note that Nepgear is one of the shyest people, err CPU candidate, I know.  She also doesn’t have a lot of self-confidence and a little naive at times. But, she’s mature and very serious about her responsibilities. I had replied with a simple yes when she asked that. While we may not share the same blood, we can still be brother and sister.

Hindsight is a bitch like her sister Karma.

It all started five months after the defeat of the Deity of Sin, Arfoire. The shares are equally split between the nations and no one has been sacrificed to the cursed blade, Gehaburn. Long story short, I owned a physical copy of the game, witch I’m in, and pirated a PC copy, ironic right? The power went out and a portal to Gamindustri sucked me in right outside of the graveyard before Compa and IF rescued Nepgear.

Anyways, I have given up hope in returning to the real world and started staying in Planeptune for the sake of Lady Histoire. Histoire is the only one who knows of my predicament and had promised not to tell the others in order to keep the time line stable. While Neptune slacks off, I’m out there doing quests to keep their shares stable. While on my off time, I continue my education that I had missed back on Earth and on the adventure.

Nepgear had been supportive about my choice helps me when she’s able to. This is where the problem started…

It started off with me taking a break and playing some Shining Star Online, a knock off of Phantasy Star Online back on Earth. Nepgear had walked in with coffee and chocolate chip cookies. She had teased me in the beginning about not giving me any like always.  When I looked back at her, I noticed that she had two cups of coffee. She had passed me my cup and took a sip of hers.

“It’s sweet, but the bitter taste melts away in your mouth, which is delicious.”

This had me asking if I could try her coffee. She had joked on how much I would have drink, making me promise to only take a little bit. It had tasted alright, but she had asked to try my coffee. I had complied and passed her my cup. She was surprise at first of the taste of it and passed it back to me.

This is where warning bells should have gone off in my head. After she promised to make my coffee with that taste, she started to mumble to herself. I had inquired what she was saying, but had insisted that she was only talking to herself. After she had teased me with the cookies, I went back to studying.

During the rest of the weak, Nepgear had been acting oddly. I wasn’t the only one to pick up on her behaviour, Compa had too. She had come up to me on my way back to the Basilicom and had asked if anything happened between us.

“Nothing out of the ordinary happened. I don’t know whets going on with her, but please, put down the needle.”

It wasn’t DDOS Arfoire, CFW Magic or Neptune, in her untransformed state, pointing a sword at me that had me afraid. It’s Compa and her innocent smile WHILE holding that unholy instalment of death pointed strait at me! We may be friends, but please don’t point a needle at me with unknown liquid inside!

On the weekend, while I was doing homework, Nepgear had walked in my room with a cup of coffee. She had set it down on the table as she was looking around my room.

“Neptue went out again?” I asked.

“Onee-chan went to Leanbox to play games with Vert and Histy is at the Guild with IF tracking down on the remaining supporters of ASIC.” Nepgear replied. “It’ll probably take her three days. It’s only the two of us here, Onii-chan.”

“I see…” I started. I had picked up my coffee and took a sip. It tasked differently than normal, but it’s usually me that adds the sweeteners to my coffee. “At least I can…” I started to nod off. “Study in… peace…” I blacked out on the desk with the last thing I heard my cup of coffee breaking on the floor.


I woke up on my bed, all tied up. My arms and legs were bound by medical gaze to the four corners of the bed. Attempting to move them found that the gaze was secured very well. I had suspected Compa wanting to intranet me for what happened. But, that idea went out the window as soon as I saw Purple Sister looking at me from the doorway. A fully naked Purple Sister with a light smile on her face as my eyes widen.

“Ah, You’re awake, Onii-chan!” She said.

She closed the door and walked towards me. The Sister was watching my reaction with lust in her eyes. It was then evident that I was missing my clothing. I’m not the fittest or overweight person around. I had no muscles on my chest or arm, or fat.

“What’s going on, Nepgear?” I inquired. Despite being transformed, she requested that I call her by her name.

She smiled and tilted her head as she was at my bed, “What does this look like to you, Onii-chan?” She asked back with innocence.

“Why am I all tied up with bondages? “ I retorted back, using a term Neptue used before.

“Heeeh? It’s so you wouldn’t run away right now.” She replied.

“R-run away from what?” I questioned with a stutter.

The younger CPU of Planeptune was silent for a moment. She leaned forward, our faces near each other. Her right hand cupped my cheek while looking into my eyes. She moved her left hand to my other cheek to hold my head in place and then she started to kiss me gently. My eyes widen in shock as her tongue entered my mouth.  After a moment, she stopped and moved her head back, her tongue sticking out.

“Onii-chan, does that answer your question?”  She questions with a blush on her face. Her head tilts to appear innocent. “Does it bother you?”

“Obviously!” I quipped. “You’re my little sister and…”

The young sister let go of my face and climbed on the bed, her maidenhood hovering over my solder.  Her soft, right, hand holding my manhood in place as she lowered herself towards it till the tip of my ‘sword’ was touching her ‘scabbard’. She looked into my eyes.

“Onii-chan…” Purple Sister started with a gentle smile on her face, “I love you”

My eyes widen at the revelation as my member started to enter her body, some blood sliding down it. She moaned as we were fully connected to each other.  Once I was fully inside, she started to ride me while still looking into my eyes. Her insides kept twitching as I felt waves of pleasure flowing through my body. After a while, the goddess leaned towards me, our faces near each other again.

“Why…” I muttered supressing a moan.

The CPU moves to my ears. “Don’t worry, Onii-chan.” She whispered in my ear. Her left hand cupped my cheek, “I won’t let you go.” Moving back, she gently kissed me again as she moved back and forth, stimulating my private. I couldn’t supress the moan inside her mouth.  The pleasure was too intense as I came inside her body.

I had soiled my sister’s body. Purple Heart is going to bring me to deaths doors, then have Compa revive me, only to kill me in the most painful way possible! Nepgear’s older sister, or Onee-chan as she calls her, is very protective of her little sister. If I attempt to run away, she will track me down. Video games, pudding and procrastinating be dammed, no one hurts her sister and gets away with it.

Purple Sister stopped kissing me and looked as me again. “Onee-chan won’t hurt you.”  Her hands went behind my back as she started to hug me, still connected. Her burst was on my chest.  “Onee-chan will be mad for a few days, but she’ll get over it.  I didn’t want Onii-chan to be lead along by the female guild members.”

I know I’m popular in the guild due to being only a few males actually going out questing. It’s mostly females that go out and get their hands dirty. But, I always go out alone, unless it’s one of the Makers or CPUs. I know I get asked a lot by female members to team up, but I always decline their offer politely. I remember IF telling me that Nepgear gets asked out by the youthful members of Planeptune almost every day and she always turns them down.

I was suddenly pushed out of my thoughts as Purple Sister continued talking. “They talked about ambushing Onii-chan on her way back to the guild.” The eye pupils started to dilate. Her movement started to get faster the more she explained what she heard. “They talked about who would go first and how they would attempt to go out with Onii-chan. They made it a contest on who would get Onii-chan on their bed first.” Her hands move from behind my back towards my cheek, holding my head in place again. “Onii-chan is mine, and mine alone.”

She kissed me as I climaxed inside her again. Her left hand was behind my head and her right hand was behind my back as her tongue explored my mouth again. After a moment, she leaned back and slowly removed my manhood out of her body, my essences dripping out from her womanhood. A tender smile on her face and her eyes returned to normal.

“As long as you have me by your side, you don’t need any of those girls.” She moved her legs to get off the bed as her eyes looked into my eyes. She looks at my table and picks up a purple rag and walks towards my face. “Onii-chan will never think of returning back to his dimension.”

I was about to question how she know, when she moved the rag over my mouth and nose. I tried to move my head, but her strength was too much. Breathing started to make her drowsy the more I took in air. I closed my eyes at the soft smile that she was giving me.

“Goodnight, Onii-chan.” Was the last thing I heard.


My eyes snapped opened as I looked around my room. The sunlight was already bright in my room. I looked at my arms and legs to find them free and myself dresses in my night clothing. I rushed out of my bedroom and strait into the bathroom, locking the door behind me. Turning on the water, I splashed cold water on my face.

“That was too real to be a dream.” I muttered to myself. Thinking back on it, I started to blush. On one hand, it felt very good and she was gentle. On the other hand, she raped me and she’s like my sister.

“Onii-chan is mine, and mine alone” her words ring in my mind.

“I’ll think of something later.” I decided. There was no point in thinking about the past. If I thought about it too much, other people might inquire what I’m thinking of. The last thing I want people to know is that ‘I’ stole the innocence of a goddess.

I turned off the water and left the bathroom. Heading back to my room, I didn’t run into anyone. Once in my room, I removed my clothing and put on my usual clothing and put on a leather tunic and pants on top of my casual wear. Strapping my twin short swords to my back, I left my room and walked to the entrance of the Basilicom.

“Good morning, Onii-chan” A voice interrupted me. I turned around and look at Nepgear. She was in her sailor outfit and holding her sword. “Going to do quests today?” She had a light smile on her face. “Can I go with you?”

“Sure.” I replied. “It’s not like you’re planning something malicious.”

“Great,” she ran up to me and started to hold my hand. “Let’s go right now.” And with that, we started to walk to the guild.

What happened during and afterwards is a story for another day.
