Step Mother's P.O.V.
I was lying in bed, unable to sleep.
My body was burning with desire, and I could feel my nipples hardening.
I tried to ignore the aching between my legs, but it was impossible.
My husband had left me for quite a while now, and the sexual tension was killing me.
'God, I'm so horny.'
I closed my eyes, trying to forget about the emptiness.
Suddenly, a faint sound caught my attention.
It was coming from Rael's room.
I got up from the bed and walked over to the door.
'Is Rael awake?'
My curiosity got the better of me, and I slowly opened the door, peeking into the room.
"Ahh!"
I heard a muffled moan, and I could see the silhouettes of Rael and Sana on the bed.
They were having sex, and Sana's cries of pleasure filled the air.
'What the hell?!'
I watched in shock as Rael pounded into her, his hands groping her ass.
'Is this a dream?'
My mind was spinning, and I couldn't look away.
"R-Rael, it's tearing, Rael! You're tearing me apart! Ahhh!!"
Sana's cries echoed throughout the room, and I could hear the sound of their bodies slapping together.
I felt a tingling sensation in my core, and I couldn't believe what was happening.
'I should close the door. This is none of my business.'
But I didn't.
Instead, I stood there, watching them in the darkness.
The sight was erotic, and I found myself getting aroused.
My hands drifted down to my pussy, rubbing my swollen clit.
My stepson, who was just 20 years old, was fucking his step-sister, who had just turned 18 this month.
The thought was so wrong, but it turned me on.
And, it wasn't the first time that I had this thought.
I had the same thoughts many times before, especially when Rael and I would hug or when he would touch my arm, or even when we would brush our fingers.
It wasn't the first time, and it wasn't going to be the last.
But still, the thought of him having sex with Sana was making me insanely jealous.
'God, why am I feeling like this?'
I couldn't control my body, and I could feel myself getting closer and closer to the edge.
The sight of Rael's muscular body thrusting into Sana's was too much, and his silver hair swayed as he pounded her.
'He looks like a beast in the dark, with his muscles and abs flexing.'
The thought was intoxicating, and I couldn't stop myself from rubbing my clit harder.
"Fuck, Sana. You're such a good girl. So tight and warm."
'God, his voice. It's so sexy.'
His husky voice filled the air, and I couldn't help but imagine what it would be like to have him fuck me.
'No! Stop thinking like that!'
But I couldn't.
My body was betraying me, and my mind was spiraling out of control.
I was getting closer and closer to the edge, and I couldn't stop myself.
"Please, Rael, please, don't stop!"
Sana's voice echoed throughout the room, and the sound of her moans was driving me crazy.
I was getting close, and I could feel my climax building.
"Fuck, Sana, I'm gonna cum!"
Hearing those words pushed me over the edge, and I came hard, my body shuddering with pleasure.
My juices dripped down my thighs, and my body went limp.
I was breathless, and I couldn't move.
I had masturbated while watching my stepson have sex with my daughter, and I loved every second of it.
"Damn, Sana, you are amazing."
His words echoed in my ears, and I could feel the jealousy surging through me.
"You're not so bad yourself, Rael."
The sound of Sana's voice sent a jolt of pleasure through my body, and I couldn't help but want to take her place.
'What is wrong with me?'
I was disgusted with myself, but the pleasure was too much and I couldn't ignore it.
I closed the door and staggered back to bed, trying to forget about what had just happened.
But I knew it was futile.
The images were burned into my mind, and I knew I would never be able to get rid of them.
"Rael..."
I whispered, my voice filled with longing.
'I need him. I need to feel him inside me.'
'But he's my son. This is wrong.'
'It doesn't matter. I need him.'
My mind was racing, and I couldn't get the image of him fucking Sana out of my head.
'Tomorrow. Tomorrow, I will seduce him. And, I will make him mine.'
'I will make him forget about Sana, and I will make him only focus on me.'
I was determined, and nothing was going to stop me.
I would do anything to have him, and I would stop at nothing to get what I wanted.
I will do anything to get his humongous, throbbing cock in my pussy.
Even if it meant sacrificing everything.
