I couldn’t help but occasionally glance towards the camera. Was she watching me now? Even recording me? My privacy was being comprehensively violated, but much to my surprise, I wasn’t feeling disgusted. I was aroused. I found myself hoping she was watching, imagining her watching me. My cock grew hard, and I wasn’t embarrassed. If anything, I made sure she could see, the thought of my own sister being aware of my arousal excited me to no end.
And so, fully aware of my potential witness, I began to masturbate. I took long, firm strokes up and down my shaft, closing my eyes to imagine Mia watching me. She was on her bed — or at least she was, in my imagination — one hand down her pyjama bottoms, touching herself as she watched me jerk off. I wondered if she was shaved or not. Would she prefer to rub herself softly, or finger herself furiously?
My metronome of strokes grew faster, and I let out a few involuntary grunts as my mind’s eye continued to present me with my sister, her other hand now rubbing her small, firm breasts. I pictured her speeding up, staring at her screen as she fucked herself. Then, I pictured her cumming. The sight of my own sister’s orgasm, though fictitious, sent me over the edge. Spurts of cum shot rapidly out of my cock, as I grunted and groaned. Shot after shot escaped my throbbing dick, as I imagined what her reaction must have been.
I was torn. Half of my brain was desperately yelling out how wrong this was. She was my fucking sister. Everything about this situation was wrong. But the other half told me a different story. ‘You’re both adults. She clearly wants you back. And let’s be fair, she’s fucking hot.’ It told me, filling my brain with various images of Mia in revealing clothing. That little voice in my head wouldn’t shut up all day. And the more I thought about her petite, yet curvy, figure — her round ass and firm tits; the more I found myself agreeing with the voice.
“Imma go take a shower,” Mia announced, as we sat and watched TV. It wasn’t uncommon for her to shower earlier rather than later; it meant that she had more time to spend with dad when he finally got home from work each day. She went upstairs and I was left alone with my thoughts and an advert for Cillit Bang. As Barry Scott’s voice rattled away, I became potently aware of the opportunity that had arisen for me. No. This was crossing a line. But, I wasn’t the one who crossed it. That makes it okay, right? No. She’s my sister. But she did it to me first. “Fuck it.” I said aloud, switching the TV off and climbing the stairs. Halfway up, I heard the shower turn on — now was my chance.
I creeped into Mia’s bedroom, to find her laptop on charge, sitting on her bed. I lay down on my sister’s bed and logged on to her computer. The ‘secret’ folder was open, and sure enough, a new file had been added that morning. But that’s not what I was there for. I found the Bluetooth connection, and brought up the video feed. Holy shit. I was actually doing this. I was actually going through with this.
There stood my sister, facing away from the camera, completely naked. Her hands massaged her soaking hair, as shampoo flowed down her bare body. Suds passed down her athletic shoulders, down her slightly-arched back, over her juicy, curvy ass. My cock hardened and my eyes grew wide as I examined my sibling’s form. I watched closely as she washed her body.
“Turn around. Please. Show me your body, Mia,” I whispered to myself, as my cock strained against the fabric of my underwear. Should I give in to my urges? Could I get away with it? These questions crossed my mind, but were given no thought. I simply pushed them aside and took out my hard cock. I started taking long strokes of my cock, as my eyes remained trained on the screen. And then, she turned around.
That fucking body.
At that moment, I was more turned on by my sister than I had been by any woman before. Her perky breasts were firm and perfectly sculpted. Her petite, athletic chest had me almost begging for the chance to kiss every inch of her body. Her clean-shaven pussy was perfectly symmetrical; an inviting slit of pleasure, I wanted nothing more than to be inside. I pumped my cock faster, wishing I could join her in the bathroom. I could give her an experience she would never fucking forget. I could fuck her so fucking hard. Shit, I could cum on those perfect tits and leave her begging, pleading for more.
I felt my balls clench, as I watched my sister scrub her body. Fuck. I was going to cum. Oh shit. I frantically looked around, searching for a box of tissues. I opened the chest on her bedside table with my free hand as I continued to jerk off violently with the other. No luck, the only thing there was a purple dildo. Shit. There had to be something, Mia’s bedroom had so much shit on the floor you’d have thought a bomb went off. There had to be something.
Fuck. I didn’t have long. I was reaching orgasm fast and I didn’t have the willpower to stop myself — Mia’s body was too irresistible. And so, I took the only option I had. I grabbed a thong from further down on the bed. Maybe it was used, maybe it wasn’t. I pulled it over my dick and looked back at the screen to see my beautiful sister’s body once more.
At that moment, I came. ‘Came’ is perhaps not the best word for what I did. Closer to an eruption. Cum blasted from my cock, splattering loudly onto my sister’s underwear. Rope upon rope of my seed pumped into her thong, as I watched her scrub herself down.
When I caught my breath, I looked down at what I had done. I knew I should’ve been ashamed, but I wasn’t. I was… almost proud. I closed the application and logged off her laptop, put my dick back in my jeans and left her room. I kept the underwear; I couldn’t exactly have just left it behind, could I? I was back in my room, scrolling Twitter by the time the shower stopped and she emerged from the bathroom, unaware of the act of pure lust I had just committed in her name.
I opened up Amazon and searched for ‘tiny hidden camera’. £60. Was it worth sixty quid to watch my sister put that dildo to use?
