My first time with sister

Note : This story is completely fictional!

it happened when I was 19 and my sister was 21 at the time. We had a love,hate relationship growing up. She's around 5'2" around 115ibs with nice tits and awesome tan skin. My parents traveled alot for their business, so we got to stay home alone alot. That summer our parents left to Europe for 3 weeks and left us behind. My mom has strict rules for us when she leaves. So one night my sister decides to take my moms car out to do some shopping (this is the biggest NO NO). On her way back she ran into a small statue in our driveway causing the front bumber some damage. My sister came inside the house in tears and started to panic. I told her she was dumb for taking the car in the first place. All night she stayed up thinking about how to solve the problem. The next day she took it into the repair shop and got an estimate for over 1,000. My sister you must understand at the time had no job and was just finishing college.

That night my sister came home and asked me for the money (I was working in a restuarant and had saved some money on the side). I told my sister "no way". I told her that she shouldn't have been driving moms car and that she should have listened to me. She kept pleading to me to lend her the money. I kept refusing. That night she was sitting at home trying to be extra nice to me. I had a few friends over and we started to have some drinks. My sister joined us for some as well. Around 10:00pm everyone had left the house. I headed to my room to take a shower before I go to sleep. My sister came into my room and said"you really need to help me out on this one" "please I will do anything to return the favor". My situation at the time was this: I had broke up with my girlfriend who never went down on me over 6 months ago. I had not gotten lucky since then. I was jacking off everyday. I really needed to get laid. As for my sister she broke up with her boyfriend over 3 years ago and never hooked up with anyone since. I told her "sorry sis your on your own on this one". I was a little mad becuase a few weeks earlier she told my mom about me getting drunk in my room with my friends.
My sister left the room and went downstairs to fix herself a drink. I followed and fixed myself one as well. We followed with another and then later another. My sister said"I am willing to do anything for that money, can't you please help me out here". I had always taught of my sister as being really sexy. I have always been attracted to her. I knew if I wanted to do anything or see her naked this would be my only real chance. I said " listen sis, I have needs, Karen and I broke up over 6 months ago and honestly I have not gotten laid since". She looked at me and said "why are you telling me this". I replied "we can help each other our here". My sister looked at me and said "are you saying you want to fuck me for helping me with the car"? I said "that will be your re-payment". She went silent for over a minute and then she said " I don't know your my brother". I told her "I always thought you were pretty and always wanted to touch you". She said "I like you too but fucking each other sounds wierd". I told my sister this is how it's going to be " I get have you any way I want till mom and dad get back, I get to call the shots and have you do to me whatever I want and do to you whatever I want, if you agree then I will help you out". My sister sighed for a moment and then said "Ok, im fine with that".

My mind was racing, hearing my sister agree to letting my do whatever to her. I didn't know what to do. I told her let's go to the living room. I told her to "take off your clothes". I was starring at my sister as she started to undress. She was wearing red panties and a red bra. As she took off her bra her tits fell out, she had the nicest tits in the world. Then she took off her panties, my sister had a nice clean shaven pussy. I was so turned on seeing my sister naked in front of me. She said "now your turn to take off your clothes". I took off my clothes (I was never gifted with being tall, but I was really well hung). My sister looked at my dick and said "oh my god, I never would have guessed you were that big". I told her "get on your knees" "it's been a long time for me". My sister replied "it's been over 2 years for me". My sister grabed my cock and started strocking it...she was barely able to fit it into her hands. Then she opened her mouth wide and got the tip of my dick into her mouth. I put my hands behind her head and tried to pull her towards me. She pulled back and then started coughing. I told her "sis put back into your mouth". Seeing my sisters lips on my dick was the best feeling ever. After a few moments, I sat her on the sofa and put her head back. I knelt down on my knees and opened her legs. She had a very tight pussy, it smelled really nice. I put my tongue in it and started to lick her. I could hear my sister letting out sighs. I licked her for a few minutes and then decided I was going to penetrate her.

I go up and put her to the edge of the sofa, I stood up in front of her spread out legs. My sister said "oh that's going to really hurt, can I just suck you off?" I told her "it won't be too bad". Then spite on my hand and lubed my dick. I knelt down and directed my dick to my sisters pussy. I slowly put the tip into her pussy. I heard her breathing loud and then she said "go slow please". I slowly strated to penetrate into her. My cock has a lot of girth and it was filling up her walls inside. I could feel her walls pulsating around the tip of my cock. I got a little more than half way in and heard my sister say breathing really loud. I pulled back out some and then headed back in. I done this a few times then I lifted her legs back to ears. She said "oh please take it easy" I was soo horny and turned on having my sister under me, penetrating into her. I started ramming into her pussy. She was yelling in pain "oh it hurts". After a few seconds she was yelling "oh please fuck me slowly brother". I could see she was enjoying it alot. I could feel my dick getting wet. My sister was cumming on my dick. She was yelling in pleasure. I took my dick out and put my two fingers into her. I then put my fingers into my sisters mouth.

Before I was started to penetrate her again she put her hand on her pussy and said "we don't have any condoms and I don't want you to cum inside me". I was not going to get dressed and got to the store to pick up some condoms. "im not on the pill or anything" my sister says. I lifted my sister and put her knees on the ground in front of the sofa...I put her face into the cushion. We were in doggystyle position. She said "I don't want you to cum inside me, im scared your gonna". I was opened her butt cheeks and spit on her ass. I took my fingers and rubbed her ass with it. I said "I will just fuck you in the ass so you don't have to be worried". She pushed me back and said "hell no, that's gonna hurt like crazy". I looked at her ass and really wanted to put it into her ass. "I told her remember our agreement?". I am able to do whatever I want to you. She said "I never had it in the ass, it's gonna hurt way too much". I told her "I will go slow and if you don't like it so can suck me off". I then put the tip of my dick in her butthole. I had my sister open her buttchecks with both her hands. I slowly started pushing foreward. By far the best feeling I had ever had, seeing my cock going inside my sisters butthole. Her opening her buttchecks for her little brother to get inside her. As I started going in she let out a load scream. I stoped and she said "it really hurts alot". I pulled out and spite on her ass....I got it really wet with my spite. I told her to open back up. I started to push inside her ass. I was feeling extrodinary pleasure. I got it half way in and my sister was screaming in massive pain. I have my hands around he hips pulling her towards me. My sister had her hands on my wrists squezing them tightly. Her fingernails were ripping through my skin. I started to really penetrate her. back and forth. I would pull her towards me with my hands and push forward with my hips. I was really getting inside her ass. She was screaming in massive pain. She was yelling " oh god ". I kept going for around 5 minutes then I was getting closer to cumming. I started pulling harder and harder. I slowy started getting up onto my feet. I was cumming...I cam into my sisters ass I pushed my cock so hard into her ass and started filling it up with my cum. I laid on her and held her in a reverse bear hug. My one hand around her neck and the other one around her hip. I cam really good. My sister was shaking and had tears running down her face. I pulled my dick out and then placed it in her mouth.

We sat there for a few minutes. She had her hands holding her stomach. She turned around looked at me and said "that was the most pleasurable and painful sex I have ever had". That night we drank some more....and I continued fucking my sister that night as well. I cam in her mouth and ass over and over again. The next day my sister could not sit on her ass all day.
