(Anna's POV)
I couldn't believe what I was seeing. Something completely outside of everything that I could possibly imagine was happening before me.
I had left my room to make a night snack when I noticed that one of the bathrooms had its light still on. I went there to make sure that it hadn't been left like that by anyone when two voices coming from it caught my attention.
"Nmn♥... Nhamn♥... Anhanmn♥..."
"Nhuhmm♥... Huhmn♥..."
I recognized those voices immediately, but my mind couldn't properly process what they were doing. I had seen videos of people doing those sounds, but my mind couldn't accept that those two familiar voices would make these sounds, especially in the same place and same time.
Slowly and carefully I approached the source of my surprise, and I started to hear more distinctive sounds as well. It was very faint but I recognized it as the sound of flesh hitting flesh, something that was only produced when two or more people were immersed in unspeakable activities.
My heart was beating like crazy. My body was heating up at such speed that I feared each of my steps was melting the floor. I felt an immense sense of dread and anticipation like I couldn't stand the possibilities crossing my mind to be a reality but also hoping to actually see what I was imagining happening.
Once I finally saw the door of the bathroom I noticed that it was very lightly open. My mind quickly rationalized as that happening because the two people inside of the bathroom were too eager for each other to notice that small blunder.
'Not wait! What the hell am I thinking?! It's just not possible! He must be watching some video on the phone. Yes, that's it! It's just a video! It can't be he and mom. There's absolutely no way that they are doing that. Absolutely not possible!'
My mind was trying to make excuses for this situation. Despite what I was hearing, my rational side couldn't truly believe what my ears were hearing.
I was completely torn on the inside. I couldn't accept the possibility of this possibly happening, but I also couldn't take it out of my head.
I slowly approached the door, the sounds I was hearing becoming more and more clear for me. My heart was beating faster and louder with each passing nanosecond until I was certain that it could be heard by the entire city.
I looked through the small fissure between the door and the wall, and then I felt like my whole world was turned upside down.
In front of me, was my little and my mom, completely naked, and having sex with each other.
HAVING SEX WITH EACH OTHER!
My mind came completely to a halt, any thoughts and justifications completely gone in an instant.
The only thing that entered my head was the image of what was happening in front of me right now.
My little brother was completely naked, sitting on the edge of the bathtub, while my mother was riding his d-d-d-d-d-d, her body going up and down.
Taka-chan was concentrated on her breasts, kissing and biting them while holding mom's back and strongly grabbing her butt.
Mom was lovingly caressing his hair while slowly rocking her body up and down, creating audible wet sounds of flesh smacking one another.
The entire scene was hypnotic, but what most caught my attention was the expression on both of their faces. Their expressions had many emotions on them, but one thing that I manage to catch in both of them was desire and love.
Both of them had looks that were so similar to their day-to-day life, but so different at the same time.
It was impossible for me to avert my gaze from them.
I don't know when, but at some point, I started to touch myself. To feel my own chest while rubbing my surprisingly wet panties. To pinch my nipples while trying to finger my own pussy.
The sight in front of me was hypnotic and exciting. My body was heating up in arousal and shame.
My mind was divided in many different directions. It wanted to scream how messed up was that situation. It wanted to turn around and pretend to not have seen anything. It wanted to stay here and continue to watch.
I couldn't control myself. I couldn't stop masturbating to that situation in front of me.
The way they lovingly started at each other. The way they changed position to another. The way they kissed each other.
It was so similar and different from many of my own fantasies about Taka-chan at the same time. I wanted to scream with them For them to stop. For them to go on. For them to let me in.
I never felt so many emotions at the same time.
I finally felt my own climax coming close. I was so excited that I just increased the intensity I fingered myself. I pinched my nipples and my clit at the same time, finally bringing to the apex of pleasure.
I came.
"GHNMMNMNN!!!!!"
I had to put my hand over my mouth to not scream.
I felt my hand get soaked from my love juices. I had already masturbated thinking about Taka-chan, but never so intensely as now.
I felt my legs getting wet. My love juices were running down my legs. My panties were practically ruined.
Then I finally realized the situation that I was into. I got up and went running back to my room. I couldn't let them see me. I couldn't let them know what I did.
I entered my room locked the door and threw myself to my bed.
I couldn't get the image of what I just saw out of my head.
'How? How? HOW?! How did this happen?! When did this happen?! Have they been doing those things for how long?! Days? Weeks? Months?! YEARS?!'
My mind was filled with questions. I couldn't bring myself to concentrate on just one. Every time I focussed on one question, a billion others came together with it.
Just as I was thinking about what just happened, I felt my body heating up again. My heart, which was already beating fast, started to beat even faster. My breathing was getting heavier. I felt the need to bring my hands to my intimate spots once more.
I started to masturbate again, trying to satiate that thirst for pleasure that I was feeling.
I continued to touch myself for so long that I lost the sense of time.
At some point in the night, a question came to my head.
'What is wrong with me?'
But that question was drowned in the sea of pleasure and debauchery I was immersed. I wanted to see more of that situation. I wanted to be part of that scene. I wanted that scene to happen to me.
Finally, I reached a point of exhaustion. I was breathing loudly, trying to catch my breath. My lings were sprawled over the bed, my sheet more drenched from my love juices than ever before, pussy in pain from how roughly I had treated for such a long time.
I felt like I wouldn't be able to walk tomorrow.
Just as I was about to pass out, too exhausted to think clearly, a single question appeared in my head.
'Will I e able to catch them again?'
And then I finally went to sleep.
