Family Understanding Ch. 01

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.

"Fine we can have sex." I said.

"Really" Sarah's eyes began to sparkle.

"But mom's home so it has to be later." I pointed out.

"No Mom had bills to pay so she left again." Sarah replied.

"Still we should spend some time making rules." I said, hoping mom would be back before anything happens.

Sarah hard an amazing body, at only 20 she looked better than a lot of the girls my age. She liked to be active and even though she had inherited our mothers 42-inch hips with her toned legs 38 D breast and flat stomach she looked amazing. Her long blond hair curled down to the tips from the perm she often got but never seemed to fully take. Suddenly I realized my body was reacting without permission, I was rock heard again and could feel my resistance washing away as I watch my sister breathing heavily while her eyes looked like she was going to eat me alive.

"So what rules do you want" Sarah said waking me up slightly.

"It's just sex so you can't get mad if I get a girlfriend." I said forcefully hoping to get her thinking about other people finding out.

"Agreed" she said while taking off her shirt, her 38 D breast bouncing heavily in her bra.

"If we don't like it we never do it again." I said.

"Fine but I know I'm going to love it" she said turning around and sliding her booty shorts to the floor.

As she bent over I watched her perfectly round ass cheeks raise into the air and spreading apart letting the thong she wore get sucked between her ass cheeks. I stopped talking and just stared at her little pink ass hole pucker at the felling of the cotton thong string grassing it.

She spun around and asked, "any other rules " laughing a little.

I know this was my last chance before I lost control my cock was already screaming for relief so I said.

"You also have to let me fuck your ass every time!" almost yelling at her.

That stopped her for a second as she stared at me with a look of surprise.

"You want to fuck my ass?" She asked.

"That's right every time." I said relived I got her to stop.

"But isn't it to big?" Sarah said a little shyly.

She slid her hands down her side's trying to in vain to hide it from me. I started to get bold, I realized this might be the best shot to get her to back off. I had learned from experience that women don't like you pointing out their problem areas even if you are complimenting the. It was a sure fire way to cock block yourself if you tried to compliment a part of a women you liked but she didn't

"No, it's super sexy and I want to ram my dick in it!" I said trying to be vulgar and scare her off.

I began to get more aggressive thinking it would make her back down, but instead she dropped to her knees and began pulling the shorts I had put on from me.

"Wait, what are you doing? Didn't you hear me? I get to fuck your big round ass every time!" I said panicked as my hard 8-inch cock sprang out and pointed to the roof.

Sarah reached out and very gently started stroking my cock with her finger tips sending electric shocks into my shaft and into my spine.

"I heard and agree I love having my ass fucked the most, I was a little worried that you wouldn't want to because it's so big so I didn't know how to bring it up." Sarah said as she looked as my rock-hard dick like it was a chocolate bar.

That was when I realized my sister knew me better than I did and I was never in control of the situation to begin with.

Sarah's eyes were now full of lust and excitement as she stared at my stiff throbbing cock pulsed at her every touch. All the conversation we had about sex growing up flashed through my mind, as the last ounce of resistance melted away, I realized that we had similar taste and if I was going to lose my virginity to someone different I couldn't do better than someone like her.

I had a moment of levelheadedness and asked " Hey Sarah are you really sure that you want this? Society says its wrong, and we would have to keep it a secret forever no matter how mad we might get at each other later."

She just looked up at me and smiled.

"Don't you remember, people used to do this all the time not that long ago, they only changed because of religion and politics changed." she pointed out.

"Plus, I know you wouldn't do anything to hurt me and I can trust you to keep me safe." she reassured me.

With that my fate was sealed, all I could do was nod I had no way to argue and no reason. Sarah every happily leaned forward now sitting on her knees.

"Can I lick it?" she asked suddenly becoming super timid.

"You're the one that wanted to have sex, I know you know what to do so just do it." I said with authority in my voice.

Sarah didn't hesitate at all opening her mouth wide she swallowed half my thick cock in one go. I knew she was trying to show off but we were both virgins and she only had practice with her toy's mom bought for her. Never the less to me it was like sitting on an electric fence, shockwaves ran deep imside me and I couldn't help but moan. I never thought a blow job would feel so good.

After a few bobs Sarah got use to my size and started using different techniques we read online added extra saliva and trying to stuff the rest of my cock to the back of her throat. She only coughed a couple of times, I was very proud of how hard she was trying, but at the same time I couldn't do anything but gasp and moan. I was feeling my self-screaming closer to finishing only after ten minutes.

"Oh, shit that feels amazing." I managed to squeak out between breaths.

"Hmm Umm Mumm" I heard Sarah try to say as she continued bob back and forward.

The feeling of her talking with my 8-inch cock lodged in her mouth shot into my core, pushing right to my finish.

"Sarah I'm gone... gone" I tried to warn her.

"Going to what?" Sarah asked, letting my cock free from her war mouth with a loud pop.

I had no time to answer her as cum shot out of the tip of my erection like a volcano. The first shot jumped three feet in the air before crashing down across her face and chest. The second shot didn't go as high but still covered her chin and tits, and by the third Sarah had very quickly sucked the head of my cock back into her mouth.

She breath out of her nose as I continued spurting more cum into her cheeks. We had read online "Sputters are Quitters" and that you could eat cum, Sarah had always wanted to try it. After I finished Sarah let go of my shaft and tried to ask something but her mouth was full of cum, she had forgot to swallow. It was sexy to see me cum sticking not only to her large 38 D breast and face but also all over her mouth, only her pink tongue peaked out a little.

Sarah gave a loud gulp and stood up sliding her finger across her face to clean some of the cum off.

"I tried to say you taste like salted caramel." Sarah said giggling, as she sucked me cum off her fingers.

"Thanks, I guess." I replied not knowing what to say, the whole experience was over whelming and seeing my sister continue to enjoy me cum kept me in a trance.

Sarah clipped her bra off and took off her panties using them to clean up the last of me cum that was still on her. It was the first time I had seen my sister fully naked in a long time. She was the type of fit that comes from teen hormones and an active life style, her breast was big but seemed to sit perfectly on her chest not slouching at all. Her body curved dramatically but with 42-inch hips she didn't seem out of per-portions.

"You know Dave I have always wanted to make you cock explode like that." Sarah laughed.

It was then that I realized how hard I had been staring at her body almost not listening to what she said.

"Oh, ya then why didn't you try anything before?" I asked trying to hide what I was thinking.

"It took a lot of courage to bring it up I was scared before." she answered back.

"Now let's see what other fun tricks I can get it to do." Sarah growled at me.

"You said you would fuck my ass but I want give you my virginity first." she said.

"Are you sure, that's going to hurt for your first time." I cautioned her.

"You already know you might bleed and everything." I said.

"Ya but I've been practicing with my vibrator and we also read that if you weaken the hymen enough it might not hurt as much." Sarah reminded me.

"Then how do you want to...?" I tried to ask.

Sarah gave me an evil look and swung her legs over mine, this caused my still hard cock to slide between her thighs. The sensation after just Cumming so hard was like dipping an open wound in lemon juice, it caused me to jump back a little.

"Are you ok?" Sarah asked concerned.

"Sure, just a little sensitive" I tried to reassure her.

I took off my shirt so I was naked to and laid back on my bed. Sarah straddled me, she was a little shorter than me so my cock ended up right between her pussy lips. Her juices were already running down and onto my shaft as she slid up and down the length. A look of lust over took her every time her hips slid forward and her clit pushed against my cock. I watched the sun beam from my window casting her in golden light, her pail skin shining brightly in the light. Her breast was heaving up and down with her every breath and even if I had no experience I could tell she was genuinely happy. Seeing her like that made me forget that we were even brother and sister and even that she was younger than me. I felt a hard thump in my heart as my blood raced faster.

"Are you going to take my 8 inches or not little slut bunny!" I said with lust in my voice.

"Dave that makes me feel so hot." Sarah moaned picking up her pace.

"Well you are fucking hot with that big ass of yours." I said.

"Shit, yes just like that!" She yelled breathing heavy.

"I hope you can fit all of me even if it's your first time." I joked.

"I'll do it for sure." she answered determined to do just that.

Sarah had to lift off me and balance on the balls of her feet. She aimed the head of my cock straight at her soaked vagina and slowly slid it into her hot waiting box. I got the same feeling like lemon juice in a wound or someone rubbing sand paper on the head of my dick. Sarah was only able to fit half my shaft before stopping I could feel a little resistance like a ring around the head of my dick but I know it was normal. I was just focusing and trying to get used to the sensations shocking my nerves, she bobbed up and down a few times trying to get a little more to fit. Then biting her lip, she put all her weight on my cock head, there was a small click and the rest of my cock shot right in.

Sarah fell forward and collapsed on top of me taking shallow breaths. She stayed there for a little while as her vagina griped and relaxed around all 8 inches of me. I knew I needed to give her time to get used to the feeling but I didn't have any time to rest as having all my cock in her just increased the flood of sensations I was going through.

"I did it." she finally said gasping.

"I told you I would get all of you in". she tried to steady her breathing.

"How does it feel?" she asked.

"You feel amazing but don't get proud just cause it fit." I answered acting all smooth.

"Don't be mean while I have you in me who know what I might do." Sarah laughed.

Suddenly she bit me right on the collar bone. I winced and slapped her right ass cheek causing a ripple to shake her ass fat which causing her to squeak.

"Umm baby that felt interesting." Sarah squealed.

"That what little sluts get when they are being mean." I tried to scold her.

"You liked it, don't try to lie I felt your little friend jump when I bite you" she said back.

"Really, you want to feel him jump?" I asked rhetorically.

I started to thrust my hips off the bed very softly at first, but even that was enough to get Sarah to squeak and moan as she sat up straight impaled on my thick 8-inch shaft. She had one hand on her left tit playing with her nipple and the other one was between her thighs. I gave a little more force to my thrust as I watched her breast bounce up and down over and over. Suddenly I realized I had gotten used to the feeling's from before and now it all felt normal.

"Shit fucking shit, your dick's so fucking big!" Sarah yelled.

It was the first time I had heard my little sister curse or talk dirty.

"Don't stop please." she begged.

"Oh, fuck that feels so good!" she moaned.

"I could go faster to you know?" I asked.

"That's... I don't know." Sarah tried to say, but as soon as I asked her vagina squeezed answering for her.

I sped up my thrust bouncing Sarah half way up my cock before she slammed back down. Now she just moaned and yelled every now and then no longer in control as she grew closer to her own orgasm. I kept up the pace, after every thrust I would give her a little wiggle so she could grind on me. After another fifteen minutes.
