Mom,sister and make three

Note : This story is completely fictional!

I am a twin.My sister and I just turned 18 last week.We are juniors at the local high school.We look so much alike its uncanny.I think she looks like a boy and she thinks I look like a girl.
We are very close and have had many long talks about sex.A year ago I talked her into us helping each other get off.We both thought masterbation alone was no good for either of us.So we would play with each other until we both came. I night I got realy hot and kissed her virgin pussy,she realy climaxed good that night.She has kissed and sucked my prick just a little ,I have never came in her mouth. Mostly we just use our hands on each other.

mom had a steady boy friend,her first sense dad left 3 years ago.My mother said " I will never close my bedroom door so you kids will never be alone. I will always be able to hear you If you need me."She keep this promise and the door stood open every night.

One night she was going to town pretty good and I stood in the hall and watched.The moon light thru the double window was it a perfect position to cast light on the two naked bodys.My prick was stand at attention as if to salute a fine performance.I about jumped out of my skin as my sister came up beside me.My prick was out if my boxer and I was rubbing it.At that moment my mother dismounted her man and took his prick in her mouth and sucked him .He was moaning very low as she keep sucking his hard on.He said " just a little more and I will cum in your mouth."She keep up the pace and he explode in her mouth. He said "you are the best cock sucker in the land."

My sister and I went back to our rooms very quietly,we might have been it shock following what we had just wittnessed.We never said a word just went right to sleep.

The next day was an early release wednesday. We were home by 1:30.My sister went right to her room ,I called her but she didn't come down stairs. Thinking something was wrong I went up stairs and rapped lightly on the door. When I opened the door she was laying on her bed nude with her hand between her legs.She looked like she had two fingers inserted in between her pussy lips and well into her cunt.I loved her cunt she keep the hair trimed very short and when I had licked it or kissed it the hair never got in the way.I went to the bed and pulled her fingers out of her and put my tongue in there place. As I licked her pussy I started to undress.Now we were both naked in the daylight.This is the first time I knew I was going to eat her pussy until she cums in my face.I stuck my tongue as far into as I could get.She was realy moaning and pumping her ass into my face.I was loving it . All of a sudden I felt a hand grab my swollen prick it was mom. She said "don"t stop you look like you are having a good time and I am going to join." She spoke in a soft voice "I have always loved oral sex and have tried to be good at it,let me know if I do good son." She took my hard cock in her mouth it was wonderful.Her mouth was so warm.I quickly went back to eating my sister once she bagan to moan.

I found it hard to concentrate on sucking my sisters cunt while my mother was blowlng me.So I went to work on her pussy and in just a minute she screamed " i'm cummmmmiinngg,lap it,lap it,lap my pussy."I had never seen her cum this much as her ass danced around the bed she soaked my whole face and I loved it.Now I looked down at my mom who was just laying there with my cock in her mouth.She had been busy watching me suck my sisters cunt dry.She released my prick and said " do you to fuck ?" Togeather we said" never just touch a little.""The way you just sucked her cunt, son I think that was more than a little " she remarked."I have never sucked it like that before,I guess we were just worked up" I said." Were you two looking in the bedroom door last night? " she questioned.We looked at each other and laughed. "Well I hoped you liked the show but now honey you got off, but what about your brother ?" she said.My mother took a new role now. She put my sister between my legs and told her to stroke my prick until it was hard.My sister did as she was told.

Within a few minutes my cock was as hard as it has ever been. It is not super big only about 6 inches,but it is thick and my mother said "son your prick is just right for sucking ,a girl can get a good mouth full and you can realy enjoy it."She ordered my sister to start sucking it and she obeyed.This was great laying back and getting your prick sucked.I moved my ass into her face so she would get more cock it her mouth.Wow!this feels good.My sister said to my mother "the head of his prick is growing." My mother asked " son are you getting ready to cum ?"Yes mom it feels so good "I replyed.She answered me with a question " have you ever been in a woman's cunt?" My reply was " no I told you I never fucked my sister."

With one swift motion she was on her back and my hard on was sitting at the lips of her cunt.She had a shirt on but took it off ,her tits were big but beautiful.My sister and I each sucked one. The nipples got very hard she spoke " you both use to like to suck them when you were small. Your father was always mad because I told him those are for the kids to suck."Mom I said " we still like to suck them.""I think my cunt is wet enough for you to slid your prick in son " she moaned.Slowly my shaft slid past the first set of lips. The second set were tighter and wetter it felt even better than my sisters mouth." Mom this is the first cunt I have ever been in and its yours I am going to fuck you realy good" I said as my voice got louder.She was moving her cunt and ass with the pumping motion of my ass.All of a sudden my sister put head up under us and started licking my balls and licking mom's crack.Mom said " sis are you going to be able to cum." Between licks she said " I have two fingers in my cunt."I raised up and into my mother 's cunt so my sister could lap more pussy.

I could feel the precum running out of my cock.Mom felt my cock growing it her." We are all going to cum togeather as a family."She was moaning.My sister was lapping my mother 's cunt I was fucking her as fast as I could and feel the cum filling my shaft."OOOOhhhhhh mom here I comeAAAAAAAhhhhhhhh fucking your cunt. oh take my juice"I yelled at the top of my voice.My mother let out a yell to match my own as my cum poured into her. Her hole was so wet from her love juice and mine I thought my sister was going to drown My sister now began to sceam out " I think I just broke my own cherry."We had done just what my mother had wanted we all came togeather.My sister did break her own cherry but her little cunt was still nice and tight,oh but thats another story.......
