My name is David and this is a real story about my family and growing up to find the worlds idea of morality is not real.
My father left my mother when I was 6 and my sister was 3, ever sense then I have taken care of the both however I could. I mostly took care of my younger sister so my mom could work, this helped my sister and I grow very close.
I took care of whatever she needed me to even if it was doing her homework or giving her a bath. We stayed close until I left for college, I became extremely busy with test and projects. My social life also eat up a large part of my time, and I even got a part-time job working in the back as a stoker at retail store. I had always been popular and had a good mix of male and female friends, but I wasn't the type of person that spent every minute with them or on the phone talking to them. The only people besides work and school that I would really talk to on the phone were family and my girlfriend at the time. My sister never complained about me being busy and I always made time to help her with school work or just hang out when I had time off. Then a few months after her 19th birthday she came to me and asked me the question that would from that point on change my view of the world.
"You know Dave I don't want to have sex with just anyone." she said.
"I know Sarah we both said that having sex should be with the people we find attractive and are good to us." I replied.
"Right so why didn't you have sex with your last Girlfriend?" she asked.
"Because we never had time alone, I wanted to but mom came home and almost caught us." I said rolling my eyes.
Even though I was 22 I still lived at home because it saved money and I could help my mom around the house. I was also going to the local city college and working part-time.
"So, does that mean you still haven't had sex with anyone?" she continued.
"Well ya I don't get along that well with others and while there are some girls in college I like I haven't asked anyone out yet." I answered.
"Then why not have sex with me?" she finally asked.
As soon as Sarah asked me that my world started to shift.
"You're my sister we can't do that." I said.
"Why not we get along better with each other than others and you treat me well, give me one good reason why we shouldn't have sex?" she asked.
"Because Incest is illegal, and the fact that we could go to jail. When we looked up incest on the internet we found out that it could cause any kids we have to be deformed." I said exasperated.
"I'm not asking you to get me pregnant you, dumb ass." Sarah said.
"I just think that we should have sex together before we do it with others that way we don't regret it later." she said.
"Besides it's only illegal if we get caught, no one would ever know." she shrugged.
I thought about it for a moment and she wasn't wrong, if it was just us no one would ever know. I looked my sister up and down and it was then that I realized even at 19 she was growing into a very attractive woman. She had developed early and already had 38 D breast, I knew I would have to threaten some guys with castration when she brought them home.
"You are too young and I'm not going to use a condom so if you want to have sex you have to oversee protection." I said.
I said that in hopes that it would end the conversation while I could still resist Sarah, she always had a way to get whatever she wanted out of me. However as soon as I said it I saw a look of excitement and lust gloss over her eyes, as she bit her lip and smiled at me.
"Ok I'll take care of the protection but you better be ready when I come back for your dick." Sarah said as she ran out of the room, not giving me time to retort.
I just stood there confused for a while part of me wanted to laugh it off as just Sarah wanting to get a rise out of me, but another part of me knew that she was serious. A few months passed and Sarah never brought it up again so I was relived and just went back to normal life.
A year later a Saturday Mom told me to watch the house she was going to take Sarah to refill her birth control and they would be back in an hour. I was in the living room watching a show, so it took me a few seconds to realize what she said. Once I did I jumped up and ran to her at the front door and asked when did Sarah stat using birth control.
"Last year, Sarah came to me and asked if she could be on it." mom said.
"I asked her if she was sexually active, and she said, "no she wanted it for other reasons" so I made the appointment and got it for her." she said factually.
Just then I heard Sarah's voice coming down the stairs.
"It helps with my skin." Sarah said.
"Besides it takes a while for it to build up in the body and start working." she continued.
I turned around and watched my little sister Sarah walk down the stairs she had really turned into a beautiful woman with curves that made you stop and stare. She moved close to me and gave me a hug so her back was towards mom, while also sliding her hand between my legs giving my cock a soft squeeze.
"We should go mom Dave can take care of the house." Sarah said turning around and pushing Mom out the door before I could say anything.
Suddenly I was very aware of how hard my cock had become, my pulse was throbbing at the revelation that Sarah had been serious about wanting to have sex with me even taking steps to make it happen. I ran up stairs and turned on the laptop opening the internet to my favorite porn site loading a few videos I tore off my pants needing to think of something other than Sarah and deal with my aching cock.
I masturbated like mad watching a big booty porn star getting fucked in the ass. As I got closer to finishing I couldn't help but notice how much the porn star looked like Sarah. The image of Sarah's ass being fucked popped in my hand and pushed me right to the edge, I could feel cum building in my shaft. I heard the actress in the video yell.
"Fuck, fuck yes fill my ass with your hot cum! Show my big slutty ass who owns it."
With that I came so hard my legs went stiff and I couldn't even aim as cum splashed all over my desk, it took 5 to 10 minutes to calm down and clean up.
I stayed in my room for the rest of the time till Mom and Sarah came home, every nerve in my body shook when I heard Sarah's voice.
"Dave we're back, are you still here." Sarah said.
"Yes, I'm in my room." I said without thinking.
Right after I said that I heard Sarah's light footsteps coming up the stairs and to my room, opening it with and sliding in she locked it behind her.
"So, I guess you already know what I want." She said with a smile.
"Sarah, I don't know what you thin..." I tried to say.
"Don't start with that, you already said as long as I took care of protection you wouldn't try to get out of it." Sarah said cutting me off.
She moved across my bedroom towards me, I could see her eyes glossed over, she wasn't going to listen to any thing I said in a normal way so I decided to try and shock her into focusing.
