Dear diary,
something fucked up happened today. I always thought of my family as 'normal'. Not perfect but at least a bit decent. Everything I thought, though, has been shattered earlier today.
I had just got out of the shower and was getting ready for bed when I heard strange noises somewhere from down the hall. At first, I believed I had imagined it but after a while I peeked out from my door and I realized the sounds were coming from Paige's room.
I was curious and so I tip-toed to her door and listened for a moment. Soon it dawned on me. They were sex sounds. I figured she was watching a porno and slowly crept back into my room a bit disgusted with my twin.
For another half an hour I managed to mostly ignore the sounds coming from the hall. But as I lay there I had the felt as if the noise being still louder. This wasn't porn. This sounded live. Oh. My. God. My sister had a guy in her room and they were fucking. I just couldn't believe it.
After all, she was always the nice twin. She started dating only after we turned 18 during the summer.
All the skin slapping, and muffled moaning was starting to make me horny even though I knew it was my sister.
I was getting really wet and in no time my panties were off, and I was playing with myself to the sound of my twin being fucked hard. She sounded just like me. I pictured being pounded just as I imagined she was being pounded.
I needed it so badly and my fingers weren't enough after a while. I reached over to my nightstand from which I produced my pink vibrating dildo. After a quick lick I pushed all eight inches of the artificial penis into my dripping pussy.
I synced up movement of my hands with Paige's moans and slowly her moans became mine as I breathed hard trying not to make a sound.
When I couldn't be silent anymore I turned on my belly and buried my face in the pillow. I was starting to get close and had to hold myself back when I heard the guy say: "Do you want me to put it in your ass?"
"Mhmm." Paige moaned.
"Beg for it." He commanded.
"Please, fuck my ass." She said in the slutiest of ways. "Please, daddy, fuck your girls tight little ass."
It should have dawned on me at that point, but I was too horny and the prospect of my twin getting fucked in the butt made me even hornier.
There was a loud slap and my sister squealed as she was penetrated by what I imagined was a huge cock. I reached over with my other hand and started gently poking at my own asshole.
