Charlotte's POV
I sat at my computer trying to do my homework from college when the usual nightly circus started.
"OH YEAH BABY SUCK THAT DICK!!" My father shouted.
We had paper thin walls in our house so if someone shouted, the whole house could hear it, realising I wasn't going to get any peace, I logged off and lay down on my bed, as I heard more and more from my parents room, I felt the standard tingling between my legs, pulled my pajama shorts off and began vigorously rubbing my pussy, usually this would do the trick but my parents seemed to be particularly voracious tonight, the more I rubbed and fingered myself the more intense they seemed to get. At the point it seemed like they were having sex practically on top of me, my pussy was gushing juices and I was thrashing from side to side with the amount of sexual tension I was feeling, I realised I needed the big guns.
"Time to break out the dildo" I said to myself.
I took my dildo out and suction cupped it to the wall, I stripped naked and put the dildo inside of me, Feeling some small relief as I bounced on top of it, i felt good and brought myself some relief until my parents began practically screaming, then the dildo felt like what it was, a poor replacement for cock, I began running my hands over my tits and squeezing my nipples, i was practically slamming myself against the wall, the floor was soaked with my juices but nothing would give, every time I came, I just wanted more.
The sound of my parents torrid fucking was now like someone had parked a jet engine in the other room, I could see the pictures on the wall and my bed shake like an earthquake, I pondered breaking out my vibrator but if they stopped for a second they would hear me, this was hell, trapped in a prison if my own sexual desire for what could be hours on end, I needed more, how the hell was I gonna get it? Then it hit me... my brother was just down the hall.
Jacob's POV
I sat at my computer watching porn and stroking my cock, while most people would have the sound on, I left mine silent, the sound of my parents having sex provided a much more realistic sound of sex than any porn film could ever create, I squirted some more lube onto my hand and slathered it onto my cock, 10 inches of British steel ready to fuck at a moment's notice, leaning back and beginning to stroke my slippery wet cock I thought of my mother, those long slender legs, that big bubble butt, the kind you only get from years of dedication at the gym, but then there was the tits, my god those tits, I had seen them a few times when I watched my mom get out of the shower and fuck, I just wanted to bury my face in them, suck her nipples and run my dick in between them, I was about to cum when without warning.
"Hey bro, whatcha watch... OH JEEZ" my sister said entering the room.
"FUCK" I shouted throwing a blanket over my lap, I had to lean forward to hide the tent but man did it hurt.
"WHAT THE HELL DO YOU WANT SIS?" I asked loudly.
"Mom and dad are making too much noise and I wondered if I could borrow your... hey are you watching porn?"
I panicked and tried to shut the tab I was on, but my sister hurried over and grabbed my hand.
"Bro it's okay, do you mind if I watch it with you?" She asked apprehensively.
"Uhh okay" I replied, feeling confused about this new side to my sister.
I moved over so my sister could lean over me and clicked play, it was a video of pornstar being fucked in various places around a bedroom, pretty basic stuff but my sister caught on quick.
