Every night since I was 16 and my half sister was 10 she has been coming to my room and sleeping with me in my bed we have a bathroom that connects my room to hers so she is just able to slip through and get to my room. I know at first it was because she was scared and our parents kept their door locked so she would come to me and I'd let her sleep in my bed and since I got up before her all I'd do is pick her up and take her to her bed before her mom came to wake her for school. It's been 6 years and I know she wants me to fuck her she will walk into my room in her bra and panties and play video games in them with me or she will get out of the shower with out a towel and walk to her room. I know some of you might say why don't you just close the bathroom door I can't it broke a few years ago. But seeing her naked is nothing new we have both seen each other naked numerous times and we have both been naked together once or twice. She is really clingy with me she always holding my hand or has her arm wrapped in mine or asking for piggy back rides. Her friends have told me she acts completely different when I'm around they say normally she is shy and quiet and don't say much but with me around she talks to everyone the smiles all the time and seem to have more energy. They've said they don't get how we are related because I'm more of a grouch and a bit of a cold hearted bastard and don't care who's feeling I hurt but they also say that when she is with me I seem more lively too but that because she my sister and I love her and wouldn't do anything to hurt her. I know she wants to have sex with me because she talks in her sleep and since I have insomnia since I was 18 I her her talk since I'm up later then everyone. We have a balcony that we share to I love the night I just love the way everything looks so I will sit out there at night before we go to bed my sister sit out there with me and a few nights ago I was out there and I hear my sliding door open I look back and see her wearing my flannel shirt I don't wear it to much because one it just started getting cold where we live and two I like my hoodie better. So she walks out and says hey bro I was looking for you I said where else would I be and why do you have my shirt on. She said well you don't wear it that much and it's clod right now so I figured you wouldn't mind if I wore it. I said I don't but it's like three times your size and looks funny. I'm 6'4 and she's 5'2 and because of my height I wear an xl not because I'm fat but because I have long arms and sizes get wider not longer. Since that night she hasn't given it back like I said I don't mind because I don't wear it that much but the last two night when she's came to my bed she's had it on she will button it up to where just her cleavage is showing and doesn't wear a bra with it and I don't know if she wears panties with it or not it goes down to her knees. But for being 5'2 she has a great body she has c cups which look huge on her and one of the nicest asses I've ever seen on a girl and she's only like 90 pounds she petite. Has has long brown hair that goes down to mid back and the beautiful brown eyes and since she only 16 but her doctors said she done growing. A few months ago I had a friend invite me to our local fair I had nothing else to do and said sure I'll go I asked my girlfriend if she wanted to go but she was sick and didn't want to go or get me sick I told her if she wants I can come over and take care of her but she said no have fun. So as I was living my dad asked were I was going I said some friends invited me to the fair and my sister heard and said can I go with you please and my dad said take her with you I said sure lets go. She said ok let me get my shoes on I'll meet you in your truck she gets there and we leave as we are driving she asks me why didn't you ask Sammy to go with you I said I did but she's sick and doesn't want to go anywhere. She said oh that's to bad we should get her something to make her feel better. I said ya I was thinking about that. We got to the fair and I bought our tickets and my friend and her boyfriend were waiting at the gate for me. We hugged and I shook her boyfriends hand because this is the first time we all hung out. I said this is my sister Lara she said hi it's nice to meet you. My friend said I thought you said you were bringing your girlfriend I said I was going to but she's sick. As we went through the fair Lara pulled me all around holding my hand the whole time. Later at night we were joined by two other girls. There was a mechanical bull that they wanted to ride I asked Lara if she was going to ride it and she said no I don't want to. But my friend did and since I was thee only one over 18 I had to sign for her and the other girl. After the fair I said bye to my friends and we went to our cars Lara said why don't we stop and get Sammy something I said we can't it's midnight I don't think anything is open right now I'll go tomorrow and get her something. Lara said ok can I go too. I said ya sure if you want. She kissed me on the cheek and said thanks for taking me to the fair it was fun I think I'm going to close my eyes for a bit wake me when we get home. I said ok night. I get back to the house at 12:30 and Lara won't walk up so I pick her up and take her inside and put her in her bed. I decide since I can't sleep in just going to chill outside for a while. I get a message from my friend that says hey that was fun you and my boyfriend seem to hit it off pretty well. I said ya it was thanks for inviting me and ya he's was cool to hang out with we should do it again sometime and if my girl is feeling better you can meet her too. She said ya defiantly then she said can I ask you sometime. I said sure what is it. She said why was your sister hanging on you and holding your hand it was a little weird. I said ya I know but she's always like that she just loves being around me and she is a little shy and doesn't like too many people so that's why she hangs on me like that. She said oh ok well I'm going to bed night. I said ok night. I go back in and get into bed and Lara is already sleeping in there. In the morning we get up I see that Lara has one of my shirts on she turns over and says morning and kisses me I said morning why do you have my shirt on she said oh well I didn't have anything to wear an I saw it on the floor when I got up to use the bathroom last night. I said that the one I had wore to the fair she said I know it still smells like your old spice spray I like it. I said if you are going to wear my shirts to bed then please ask me first. She said you're not mad are you I figured you wouldn't mind. I said you should still ask now get your butt and shower you've got to go to school and I've got work. She said then lets both shower together it's not like we haven't see each other naked before. I said ok lets do it just don't tell your mom or dad. She said my lips are sealed. We got in the shower and Lara said can I tell you something. I said sure what is it. She said I think I should be your girlfriend Sammy doesn't treat you to good and besides I love you more then she ever can. I said we can't your my sister it wouldn't be right. She said I'm only your half sister remember so it's only half wrong and besides if you don't want any then why did you get in the shower with me, I know you like my butt and boob I see you checking me out all the time when I'm in my bra and panties or when I get out of the shower. I said well you walk around in my room in your bra and panties and sit there and play video games in them too and you know my door is broken to the bathroom but you still choose to get out with out a towel and besides I've seen you starring at my dick too. She said well still you are naked in a shower with your little sister who is helpless to defend herself to say if you were to get a boner and shove it into my tight little pussy there would be nothing I can do. I said so what your saying is that you want me to bend you over and fuck you while in the shower. She said ya if you want to put it that way then yes I want you to bend me over and fuck my brains out and cum in my pussy. Then she said your already hard just from talking like that so I'm just going to bend down to wash my leg and if you want to fuck me with that big thing while I'm washing my legs then I can't stop you here I go. She bent over and I looked at her while she looked back at me then she wiggled her ass and said just do it we both want it to happen. So I shoved my dick in her and she was tight but she said she's never had a big dick before the biggest that she had was about 5 inches and I had that beat by 3.5 inches. While I'm fucking her we heard her mom bang on the door and she says hurry or you will be later for school and your brother still need to shower too she we stopped but I kept my dick in her so she could get use to my size and we washed our hair and finished up then I picked her up and put her on or bathroom counter and fucked her hard for about 5 minutes then when I was close to cumming I told her and she said stay in me I want you to fill my pussy up please don't pull out. I cummed in her pussy and it was one of the biggest loads of my life. She said wow I'm so shaky right now I don't know if I can walk. I helped her down and got her to her room she got ready for school and put on a skirt and came in my room and said I don't have panties on so when you go to drop me off pull to one of the side roads and we can fuck again. We did and I left another huge load in her pussy. I pulled in front of the school to drop her off she kissed me and said see you later. I said see ya. She said I love you and I said love you too have a nice day at school. When I got home from work I got to my room and saw I had a few text from Lara she said think about you can wait to see you tonight and sent me a picture of her pussy with my cum dripping out of it then she said don't worry I had panties in my bag and put them on. When she got home she come right to my room and says I almost got caught today while all the cum you pumped in me. I said what do you mean. She said I was giving a presentation and in could feel you cum start to drip down my leg so I had to finish it quick before anyone noticed to white stuff going down my leg. I said sorry but you were the one who said not to pull out. She said its fine we just have to be more careful. I said that for sure and you need to get on birth control so I don't get you pregnant and I need to get more condoms. I said well I'm going to get Sam something to make her feel better then Lara said or you could just fuck me again. We've been having sex for about 5 months now and it's only gotten better and since today is Halloween our parents are going to a party and I'm taking her and her friends trick or treating. But Lara said when we get home she going to give me a real treat and she wants one from me she said she wants me to cum in her mouth we've only done that twice before. Man I love Halloween and Lara I will let everyone know how tonight goes in the next day or two.
