It was almost 12 o’clock when my sister came home from school today. Before we fell asleep, I noticed that it was almost five in the evening. So it was clear to me that my sister and I had been fucking for four hours or more! I couldn’t believe that I fucked a woman, much less my sexy little sister for that long! The longest I had ever had sex, was with Allison, and it went for almost two hours! Then again I had never cum so hard, and never as much as I had today! And to be honest, it was by far the best sex I have ever had in my life! It was amazing! Had I known that incest was so damn sexy, hot, and kinky, I would have tried to fuck my sister when she moved here! My mind was blown!

I think it was because of the taboo of the whole thing! Incest is strictly frowned upon by society! It came with serious consequences, such as jail time and what ever else there may be! Then again It explains why I loved it so much! And to make things more sexy, was that my sister is four years younger than me! She was seventeen, and still in high school! I fucked my 17 year old little sister!

I had already awaken, it was now almost 10, and I was thinking about what had just happened. I now understand why my sister had the philosophy she did. You are in as much control of who you are sexually attracted to, as much as when it rains. I knew I was sexually attracted to her since our photographer game! Apparently, she was sexually attracted to me! I was in heaven! I didn’t regret what had happened with us today at all! It was almost life altering!

She then began to stir as my sore cock stiffened. I looked down at her sexy petite body as she began to wake up. The way my stiffening cock felt brushing across the soft skin of her face, sent chills through out my body! She woke up and placed her face on my lower abdomen and faced down. I felt her hot breath on my cock as she began to breath harder. She gently wrapped her hand around my cock and caressed it gently, making it twitch. I let a long breath out as she touched my cock! Be careful, its kind of sore right now, I whispered. But its so hard, she said. God I love this fucking cock, she said as she began to sit up. Its so hard baby, she whispered. I can’t help it, you are amazingly sexy, and you being naked and touching it is making me hard again! She giggled as she stood up. She gently licked my cock on her way up.

She looked into my eyes with a very seductive look. Why is that sexy cock of yours so sore, she asked. Because your pussy is so fucking tight, I responded. Well, we have a problem then, my pussy hurts too. I have never had a cock that big in me, she said. I would fuck you again, but its too sore. But that’s ok, cause when we aren’t sore anymore we are definitely doing this again!! God your so sexy, she said as she walked out of the room. I thought she was going to go get dressed, but instead she came back out naked. It was very difficult to concentrate on our conversations while she sat there naked.

I forgot what we were even talking about, I was too busy looking her gorgeous sexy little body over! She had a very athletic build. Small sexy tits, a 6 pak with a belly ring, and her fuckable little shaved pussy! My cock started to get hard again.

That’s when I noticed my little sister stop mid sentence and started staring at it. She smiled, and then she kissed me. We started to make out like a pair of horny teenagers. We stopped and she said, any girl would be fucking stupid to not want to fuck your brains out. Even your own sister. You should really think about doing porn, I’de bet you’de be amazing at it. I know ide watch!

I kissed her passionately in response. Ok now that we have established that we both find this new incest game is just fucking hot and sexy, I think we need to change our game now. Ok I said, what are we changing it to. She got a very seductive look on her face. Then she said, to what it really is. Brother and sister who find incest to be the freakiest thing out there! We will keep it as quiet as we can, but now we just have to go out in public and try to turn each other on, without getting caught. I like that game, I said. You’re on!

For the rest of the night we couldn’t have sex. My cock hurt from her tight pussy, and her pussy was sore from my big cock. She was walking funny for the rest of the night. She did however go ahead and measure my cock, and took pictures of it along side of the tape measure. It measured a little over 9.5 inches! She and I were both amazed! I didn’t really know the exact size. I only guessed 8 or 9 because that’s what I thought I heard Allison say. It was 3 and a half inches thick from side to side, and from top side to underside! God! No wonder my pussy hurts, she exclaimed. But oh god it felt so good!

Can I send these to Katie she asked. Only if I can see what she says, I replied. Ok deal! She sat up against me and began to send the pics to her, with a caption that said, this is why I left school today. A few seconds later Katie replied. Oh my god!! Is that really his cock?!

Sister: Yup,

Katie: oh god, its over 9 inches long! I don’t think I have ever seen a real cock that big!!! How big around is it?

Sister: its about 3 and a half inches thick all the way around!

Katie: did you fuck him?

Sister: Oh god yes, I had to! I had so many orgasms,

Katie: God I am so jealous! I wish I could have that cock! Its fucking huge! Is your pussy sore?

Sister: Yes it is!

Katie: oh god I wish I could find a cock that fucking big! I wanna see and touch that!

Sister: hang in there sexy, you might get too

Katie: omg really!!?

Sister: I’m trying too talk him into it. He is just nervous about it. You’re only 16 so he isn’t sure about it yet. He thinks it sexy as hell that I’m bi! He wants to watch us!

Katie: oh my god I’m getting wet!! He doesn’t think its disgusting like my boyfriend does?!

Sister: nope in fact he thinks its hot, and wants to watch me with a girl!

Katie: I would sooo do it! If he has a cock like that ill bet he could fuck us both too! How old is he?

Sister: he is 21 and about to be 22

Katie: so why is he nervous about being with me? Your only 17, and my brother is his age!

Sister: that’s what I keep telling him, well except the brother part but Im having a hard time convincing him.

Katie: well tell him I said that I promise to never tell anyone!! I wanna see his cock in person so bad! I would love to suck that huge thing! Well that is if you let me! Lol

Sister: oh my god I would love to see that!!! Its making me wet thinking about it!

Katie: so you would actually let me touch that beautiful cock? Your boyfriends cock?

Sister: I wanna watch
;-p ide even guide his cock in your pussy if you want?

Katie: god you’re turning me on!!

Sister: good!

Katie: I’m touching my pussy right now! When can we do this?

Sister: ill talk to him tonight. He has to work on Monday and he and I are going out of town for a day or two.

Katie: ok, please tell him I said that it will be our secret, i promise to never tell anyone ever!

Sister: ok I will, maybe that will convince him! I hope!

Katie: omg so do I!! I wanna see that cock so bad! Gotta go, I need to go fuck myself now, wish you we’re here!

Sister: I wish yu were here too! Love ya sexy have fun!

Katie: oh god, I already am!! Love ya too!

My hot little sister closed the screen on her phone. She layed on me basically and began to rub my hard cock with her soft little thigh. So what do you think baby, she asked. Well I’m not too sure yet, she may have made a promise, but I’m still not too sure, I said. Please, she begged. I want this so bad! Plus she obviously isn’t an idiot, she has seen your cock, she fucking herself right now! Its not going to be a whole lot different than us, I’m still technically a minor, and you fucked me. She sat up in my lap and began to gently run her drooling pussy on my sore cock! She kissed me, then placed her forehead on mine, looking straight in my eyes.

Ok I’m going to let you in on a little secret, she said as she gently caressed her sore drooling pussy on my cock, wetting it. Ok, I said. Well, you know how you haven’t seen her for a while. Yes I said as chills ran through my body. Its because she has been fucking her brother! He’s 21. Wow, I whispered. That is sooo hot! Its just that your cock is so fucking beautiful, that I want to share it with her, she said with a shaky voice. Please baby, she whimpered., I’ve already had this sexy cock of yours in my pussy, now I want to have a threesome. Ive never done that, and you’re absolutely perfect to do that with, please? I wanna see if you can make her squirt like you did me. I never knew I was a squirter until I fucked you! Please baby! You already fulfilled my fantasy by fucking me till we were both sore. Please, she promised to never tell anyone, and I for one believe her, and I trust her.

Ok I said, let’s do it. Really she asked with excitement. Yeah let’s do it I said. She may be young but you’re right. She is sexy as hell! I love her milky white skin with her blonde hair and big blue eyes, I said. God I know right she asked. She is going to love that cock of yours! I can’t wait she said.

I reached over and kissed her. She fucks her brother too, I asked. Her eyes were partially closed. Mm hmm she answered as she layed there. Does she know your boyfriend is really your brother? No she said, well just surprise her with it. God I can’t wait, I said. Me either, it’ll be both of our first threesome she said. So how do we do this, I asked. Don’t you worry about it sexy, ill work it out! Mmm ok, I said as I kissed her!

Wait I need to tell her. She picked up her phone. And shot her another text.

Sister: guess what you sexy slut.

Katie: hold on I’m going to go fuck my brother

Sister: oh god that’s so hot! Ill just tell you then, my boyfriend said yes.

Katie: oh god……ok well talk about it in a while, my pussy needs my brothers cock bad especially after this text.

I about choked after I read that. There you have it baby, my sister said.

So, what made you decide to actually let me fuck you, I asked. Well you know how I told you before that you’de be surprised at how common this is, she asked. Yes, I replied. Well I decided to do research on incest. The more I thought about it, the more the idea of having sex with you got better. Its just fucking hot, and it was just making me want your cock in my pussy! Like I said, its a lot more common than I even thought. Its mostly father daughter, mother son, but, the one that made me the wettest was the brother sister. Between that and Katie talking about how she and her brother have sex, just made me decide that I had to have you! And that’s when I decided to try to get your cock in me. When you sent me that yes, my pussy got so fucking wet!

Oh and one more thing baby, she said. I’m on birth control so you can cum in my pussy all you want. The rest of the night was uneventful. We were to sore to fuck anymore. We stayed naked for the rest of the night and cuddled on the couch before we went to bed.

The next morning is when I noticed the pain more. I got up and made breakfast. When she came down she was wearing her robe and that was it. It was opened all the way and resting between her small teen tits. I couldn’t keep my eyes off of her! She couldn’t keep her eyes off of me either. I was only wearing boxer briefs. We ate our breakfast as we sat there eyeing each others bodies. If I wasn’t so sore I would fuck you hard again, she seductively said. We didn’t go anywhere or do anything. I did eventually got dressed and we hung out in the living room. I couldn’t keep my hands off of her. I continued to touch her little teen tits, and did so for most of the day. She would just sigh and breath as I did so. My pussy is so wet right now, she would say. I wish I wasn’t sore! I continued to rub her tits and her stomach.

A day passed by and I returned to work. I ended up picking up a couple extra shifts and got some over time. My sister would keep sending me pics of her amazing teen naked body. She would always send texts as well. My pussy isn’t as sore anymore, or, god I miss your cock! She then started to send me pictures that made me really hard! While I was at work she went to the porn shop and got a big fuck toy. Its not as big as your cock the caption read. Then I got a picture of her pussy! Its so small that all you could see was her bald pussy slit! Then I got pictures of her sliding her dildo in and out of her pussy! She sent me a video of it too! I loved hearing her little voice whimper and moan as she fucked herself.

At the end of the video she picked up her phone and and looked at the camera. She said, I hope your cock isn’t sore, and I hope you don’t work late. I really need your cock and your cum in my pussy. Ill see you when you get home.

A the end of my shift I went home. As I walked in the door, there my sexy sister stood. She was in the kitchen washing a dish. I closed and locked the door as my cock began to stiffen. She was wearing a very short skirt. She looked over her shoulder at me. As I dropped my bag and began to walk to her, she said, oh god I’m so horny for you baby.

I walked up to her as my cock buldged against my uniform pants. My cock ached as I wrapped my arms around her. I reached up and squeezed her tiny tits. She leaned her head back with her eyes closed as she whimpered. I kissed her and began to nibble on her neck. She pushed her ass onto my bulge and began to grind her ass on it. Her hand reached behind her and gripped my throbbing cock and rubbed it through my pants. I reached down with my other hand and found her soaked little pussy.
