Inside the dim room, with all the lights off and the curtains closed, I saw my sister sitting at her desk with headphones on and a blanket on her shoulders, watching something on her computer monitor.
At that time, I was relieved that she was safe and sound, and let out a sigh of relief, and relaxed my tense nerves. But that relief didn't last long, as my heart rate spiked again, when I saw what she was watching on her computer.
On her monitor screen, was some kind of game where there was text and dialogue at the bottom of the screen, with some prompts included.
And what was playing on the entire screen, was what shocked me the most.
On the screen, was what seemed to be a human girl with a snake's body below her waist, and a boy in an empty classroom. The girl was using her long snake tail to wrap around the boy, and she lifted him until his abdomen was next to her head.
She then proceeded to take off his pants until his dog was hanging down, and started to use her long tongue to suck him off.
If this 18+ scene on my little sister's computer, wasn't shocking enough, then how my sister reacted to it was even more jaw-dropping.
Since she was wearing her headphones, she couldn't hear me come in. And since I was standing right behind her, she hadn't noticed me.
Because of this, I could take my time and clearly take in the happy and excited expression my sister had on her face, while she watched this scene unfold, as if she had been waiting for it, for a long time.
I could also see my sister clicking on the prompts that would trigger the dialogue of the characters in the game, which means that she was the one in control of this whole scene, which I later on learned was how visual novels were played.
If I had walked in on my sister watching some kind of porn video or some snuff film, it would have made much more sense, as it's something all high schoolers go through in that stage of their lives.
But to see my sister, whom I thought was innocent as a mouse because of her shy demeanor, watch some kind of weird video where a snake girl was dominating a boy in a school classroom, was more than enough to short-circuit my brain.
I wanted to do nothing more than get out of her room immediately, as too many thoughts were going through my head at that time, and I needed some time and fresh air to think it out.
So, just like I planned, I rushed out of my sister's room as fast as I could.
But because of my frantic escape, I accidentally hit the switch board and turned on all the lights in the room.
I froze at that moment, and turned around, praying that somehow my sister didn't notice that the lights were on. But sadly, even though she couldn't hear anything going on because of her headset, she could still see perfectly.
Both of us stared at each other in that silent room, with dreadful looks on our faces.
One's face was so red that she looked like a little cherry, and the other was so pale that it looked like a ghost.
My sister was embarrassed that she was caught, watching something unexplainable by her long-lost brother. While I was regretting not knocking on her door harder, instead of barging into her room.
Her face only turned more red, and mine more pale, as if I didn't have a drop of blood in my face, when I saw the rest of her room, which I couldn't see before because of how dark it was.
Now that it was bright and well lit after turning on the lights, I saw that her room was full of demi-girl themed goods and merchandise.
Her cabinets were filled with figurines and sculptures of different demi-girls striking provocative poses, and her walls were covered in colourful posters of cute demi-girls.
It clearly looked to be the room of some nerd, who was obsessed with demi-girls.
At that time, I hadn't learned the term demi-girl or what my sister was interested in, and I just thought she was one of those furries, that seemed to be trending these days.
I wanted nothing, but to run out of her room and escape this awkward situation. But my legs froze, when I saw my sister trembling in embarrassment, and looking like she was going to cry her heart out.
With the amount of issues she already had, it looked like she would never recover from this accident if I left her in this room, and would have a mental trauma from this incident for the rest of her life.
Furthermore, I was sure that she would never accept me as her brother, if I left things as they were.
So I decided to deal with this situation in the best way I could think of.
That was, to show interest in this weird hobby of hers, and act like I was genuinely intrigued by it.
The only way a person with a strange hobby would be comfortable showing it off to another person, would be if that person also had the same interest, or at least was genuinely interested in learning about it, without any prior stigma.
So, I too acted like I was interested in her hobby at that moment, and walked around the room while I observed her dolls, figurines, paintings, posters, and everything related to demi-humans.
She looked like she wanted to stop me from looking around her room, out of embarrassment. But she was too afraid to say it out loud due to her anxiety issues, and she reluctantly let me be, and watched me look around her room in silence.
After getting a good look around her room, I faced my sister with a look of interest and curiosity on my face, which I made up, and started to ask about her unique hobby.
She didn't answer at first, and she looked shocked that I was even showing interest in her hobby.
I later learned from her, that she was expecting me to look at her with disgust, and start scolding her for having such hobbies. But I was really surprised, when I started to question her about her hobby with interest instead, which she didn't expect in a million years.
After endlessly pestering her with some questions I made up on the spot, she finally gave up her resistance out of nervousness, and started to answer my question in a low and timid voice, as if she were afraid that I would lash out if she said anything wrong.
That was probably the first time she talked to me, instead of the usual grunts I hear from her room, when I call her.
