Dirty Sister gets me caught by mum

100% fiction!

Im in quite a reasonable family of 5 mum, dad, sister, brother and me. Im the youngest of all and the oldest being my brother who lives away from home. My sister is a young 22 year old with a hot body and still lives home with me.

I often had fantacies of doing things to my sister and when she was away i would look through her draws for her sexy bras and toys. I had found her stash of 3 dildos one being a vibrator and the other 2 large rubber ones.

Most days i found myself home alone because of not having a job and both my parents and sister do and do not get home til at the earliest 6 o'clock. Most days i would play x box then jack off to some porn. On some days i would grab my sisters double d bras and rub them against my penis and have fantacies.

One tuesday i found my self with nothing to do at 4 o'clock in the afternoon. I was feeling a bit horny and hadn't let off a load all day and since no one was getting home for hours i decided to do it. So i got out my laptop and hoooked it up to the tv and opened up some porn videos. I took a comfortable seat on the lounge and brought out my cock that is about 8 inches. After stroking it for a while to get it hard whilst watching the porn i pulled out some lube to use. Now i was really starting to get into it and making fast motions. Little did i know my sisters car just pulled up out the front and she was making her way to the door. As it was plugged into the TV the noise was quite loud and she heard it as she approached the door. She decided to open the door quietly and tip toe in.

She peaked around into the lounge room and saw me batting off and was stunned which then broke out into a little giggle. She then started to rub her clit a bit through her pants without noticing. She then snapped to it and walkedd around the corner it took me a good 10 seconds to notice. When i did i quickly covered up and was very embaressed. I then stood up and she asked " what are you doing" i then backed away and resonded "nothing." she then said "thats not what it looks like" I had nothing to say and was stunned and seeing her in her tight blouse with her big double d's almost bursting out made my cock even harder. She said " sit back down in that chair" i then scuttled back into the chair. She said "i dont know what to say" whilst crouching down. She then reached to me grabbed my cock and said "your cocks a lot bigger then i thought it would be, well actually bigger then anything ive fucked." I was so stunned she was touching my cock and told me it was big. I also couldn't help but notice the porn on the tv in the background. She then sighed and said " well am i gonna tell mum and dad?" I didnt answer "well" she said " i am your sister and you should be able to trust me so i wont." "thanks sis" i said, she replied " but i still cant get over how big your cock is, if its alright with you can i suck it." I didnt know what to say i just got up and guided her head onto it.

"thanks bro" she barely managed to say as she was swallowing my cock. I then started to pull down her blouse to see those huge tities i had dreamt about. I pulled them out and thought they were even bigger then i could have imagined. I wanted to lick them so bad but i couldnt interupt her cock sucking. I decided to help her out so i grabbed the back of her head and shoved my cock down her throat and listened to her gagging then gasping for air. I let head go and said " im naked how about you now??" she responded "if i pull everything out you have to go down on me."

As she new the answer she started to take her clothes off and i could see her perfectly chisled body. I then ate her pussy which was the best thing i had ever tasted my tounge went crazy on her clit and i made her eyes roll back. I put my fingers in her pussy and started licking her asshole and putting my tounge in it which i was not sure if she would like but she seamed to. I then finally got to licked her massive boobs the tits were already hard when i started to nibble at them. She then started yelling at me as if she was angry " Stop fucking around and start fucking me"

Yes please i thought i stood up and pushed her back on the lounge more then jammed my cock into her pussy and listened to her wail. "Ohh yer fuck me she screamed." I continued to fuck her hard and then picked her up with my dick still in her pussy and i lied down on the lounge and got her to fuck me. I hadnt even noticed the porn was still on the tv until when we were in the reverse cowgirl and she was facing the screen she started to slow down the fucking and said " so you like anal" i yelled "what" she responded "well there is anal in this film and actually ive always wanted to try anal i thought it might be painful yet pleasurable. I wouldve done anything for her right now but without any response from me she bent over and said "come on lets do doggy style anal" so with hesitation i got up and jammed my cock in her asshole this being a first time anal for me too. I jammed it in so hard she screamed "AHHHHHHHH" i didnt know whether this was a pleasure scream or id killed her i stopped. She then yelled at me "you fucken cunt keep fucking my ass" so i fucked harder and faster then ever before and her asshole was even tighter then a virgins pussy and it felt so good. It felt that good i screamed at her "im gonna cum" as i yelled this i looked up and there was my mum on the couch. I came in her asshole and when i had realised i yelled at my mum " fucken hell look what youve done you can lick that out of there now"

i pulled my cock out went and grabbed her took off her clothes and shoved her face on my sisters asshole. And the observed her fine body and thought like mother like daughter i suppose. i then yelled at my mum "lets see how you like it" i shoved my cock in her ass and she screamed "NOOO" her ass was just as tight as my sister but felt different and i wondered why. Curious i pulled my cock out "WHAT THE FUCK YOU MOTHER FUCKING WHORE" there was SHIT all over my dick "you can eat that off you dirty fucking whore. I made her eat every single speck then told her to go and cook dinner while i fucked my sister another 2 times.

I have continued to fuck my sister atleast once a week since this and i finally got to anal my mum without getting shit all over my dick. We have a dirty incest anal threesome every week now.
