I have a brother who is the same age as me.
When I was three years old, my parents remarried,
and my mother's stepson, who was two months younger, became my brother.
It was the winter of my senior year in high school.
I was molested on the train to school.
I had often been molested,
and I was quite lewd,
so if the person was my type, I would let them touch me.
That day, it was a young office worker who was my type, so I didn't resist when he touched me boldly, and he slipped his fingers into my panties and stirred me up.
I managed to suppress my voice, and just as I was about to climax, the train arrived at the station,
leaving me frustrated and heading to school.
I spent the whole day feeling frustrated and went home,
and as soon as I got home, I went to my room, remembering the morning's molestation,
took off my panties while still in my uniform, and masturbated twice.
I often had sex with my boyfriend, but he always came first,
so I was never satisfied and always relieved myself through masturbation.
One Saturday afternoon, my brother came into my room with a laptop and said,
"I've got an interesting video, you should watch it!"
When I refused, saying, "I don't want to watch it,"
he said, "You should watch it, it's for your own good," and started playing it.
To my surprise, it showed me in a compromising position, taking off my panties and inserting my fingers.
"You're dating A from class 1, right? What would A think if he saw his girlfriend like this? Should I email him?"
"Please, keep it a secret," I begged.
"If you do what I say, I'll keep it a secret. You know our parents won't be back until night," he said.
I thought my brother would do something lewd to me,
but I was excited by the situation where I couldn't do anything because he had something on me,
and I was looking forward to being touched by my brother, who had a big body trained in judo, unlike my bland boyfriend.
"Alright, let's get started," he said, tying my ankles together with vinyl tape.
"I saw you being molested on the train the other day, looking so lewd and enjoying it, but you looked disappointed at the end because you couldn't climax."
He had seen me.
I suddenly felt embarrassed and said, "No, please stop, this is too much."
"No way, I'm not going to stop halfway. I'll make you feel good," he said, rolling me onto my back on the bed.
"Wow, what a lewd bulge,"
he said, pressing his fingers against the center of my panties and playing with me while watching my expression.
"First, I'll teach you how to masturbate properly," he said, turning on my father's electric shaver with the cap still on.
The vibration approached my crotch,
and I felt a mix of anticipation and anxiety.
He pressed it slowly against my sensitive area through my panties,
and I forgot my embarrassment as I felt a pleasure I had never experienced before.
I think I came in less than 20 seconds.
"Amazing, right? I'll make sure you can't go back," he said, rubbing it against my sensitive body again, making me climax once more.
"How is it? Amazing, right?
Dad will be happy to smell the shaver,
look how soaked it is. Let's see what's under the stain,"
he said, pulling off my panties from behind and exposing everything in front of him.
I could feel his gaze focused on one spot.
He spread me open with his thumb and observed me closely.
Even my boyfriend had never seen me like this.
"Alright, since we're here," he said,
taking out his phone and filming everything.
"No, please stop," I said, feeling so embarrassed that my body heated up.
"Oh, you're turning red. Let's do something more fun," he said,
turning on an electric toothbrush and slowly rubbing it against my sensitive area with his left thumb.
The different stimulation drove me crazy.
The intense pleasure made me climax in no time.
Even after I came, he didn't stop, making it hard for me to breathe,
and I felt something gush out.
"Sis, you're serious, you squirted," he said in a lewd voice.
"Now, let me have a taste," he said, getting naked.
His body was muscular and well-trained, unlike my boyfriend's.
I was about to be violated by my brother. It shouldn't be allowed, but my anticipation grew,
and my brother was doing something.
He was stuffing ping pong balls into a condom.
One, two, "No, I don't want that," "I'll stimulate you deep inside,"
he said, pushing them inside me and then violating me.
The intense thrusts made me dizzy, and I couldn't tell if it was pleasure or something else.
Even so, my brother remained calm and finally ejaculated on my stomach,
saying, "It would be bad if you got pregnant."
After that, he filmed himself slowly pulling out the condom with the ping pong balls from inside me.
As he untied the tape, he said, "This is our secret. From now on, you'll be my sex slave. You can't tell anyone, I have the video."
Since then, he made me service him with my mouth every day,
and he tied me up and played with me using the shaver.
