It was my sixteenth birthday and my sister Shayla had just taken me out to the movies, and had asked me if I wanted to spend the night at her house, and naturally I said that I wanted to because it was so boring around my house with nothing to do.   Shayla was ten years older than me and already out on her own, far away from the nagging and ranting of our parents.  I told her how lucky I thought she was, because she could do anything she wanted to, while I was stuck at home for at least the next three years.

We got to Shayla's house and we went inside.  Shayla took off her coat at the door, and was already in the process of changing out of her clothes with each step she took down the hall to her room.   By the time she reached her bedroom door, I took a look down the hall and could see that she was down to her black lace bra, and her matching thong panties that put her tight, curvy ass on display.

Shayla disappeared into her bedroom, and came out a few seconds later in a buttondown  nightgown that barely covered her panties that could clearly be seen through it anyway.  I also noticed that she had ditched the bra, and her nipples strained against the material.  With each bounce of her breasts, the entire nightgown seemed to bounce a little bit wiith them.   Shayla plopped down on the couch next to me and took the tie she had out of her hair, letting her long brown locks fall down around her shoulders.  As she flipped on the TV, she reached for her hairbrush and began brushing her hair out.

"So Mark, has Mom let you have a girlfriend yet?"  Shayla asked, obviously inquiring about any changes that were made, if any, to our mother's overprotective and sheltering parenting style.

"Nope.  I cant even go over to Jacob's house now, because Mom thinks Im going over there to meet a girl." 

"I cant believe she still hasnt changed.  Youre sixteen now and still have never had a girlfriend." 

"I guess its not so bad if you dont know what youre missing." I said.

"This might be a little personal, but Im your sister and you can tell me.  How are you holding up..um...raging hormone wise?"  Shayla asked.

"What do you mean?" I said.

"Well, teenage boys are all....you know...horny as hell." Shayla said.

"Yeah, I guess." I said.

"Well, do you get to look at naked women on the internet?" Shayla asked.

"I cant.  Mom has the parental thing on so nothing like that is accessible." I said.

"That figures.  Do you have any magazines or movies?" 

"No.  Mom would kill me if she found out I had anything like that." I said.

"Have you EVER seen any dirty magazines or movies?" Shayla asked.

"No." I admitted.

"Youve got to be kidding me Mark.  Have you seen any naked women at all?"

"Just some I saw in a couple of movies, topless girls.  Mom nearly flipped her lid.  She was yelling and screaming about it for a long time."  I said.

"Wait here a minute." Shayla said, and went off to her room.

When she returned, she slid a videotape into the vcr, and immediately a gorgeous, big breasted blonde was on the screen, naked and moaning as she was being fucked doggy style.

My eyes were glued to the screen, and my cock was instantly hard and forming a tent in my sweatpants.  Id never seen anything like this. 

"Never fails.  If you want to get a guy's dick hard, just show him a naked blonde with big tits." Shayla said, casting her gaze down at my glaringly obvious hardon.

I shifted uncomfortably in my seat, my body temperature rose uncomfortably high, and I knew my face had to be bright red.

"Dont be embarrassed Mark.  Its perfectly normal.  Especially for a guy your age who hasnt seen anything like this before." Shayla said.

I sat up on the couch, trying to reposition myself so that my hardon wasnt as visible, and did my best to try to get over my embarrassment and get my facial color back to normal.

"Look Mark, Im not trying to embarrass you.   I just want you to know that when youre here at my house, you can do whatever you want to.   You, just like every teenage guy need an outlet for your sexual desires.  Not only that, but you need to have some idea of what youre supposed to do when Mom finally releases her iron grip on you and lets you have a girlfriend.  Theres nothing worse for a girl than when she wants a fuck and the guy has absolutely no idea what he's doing, and then blows his cum before the fuck ever gets going because its the first time he's ever seen a pair of tits and a wet pussy." 

"If Mom finds out about this..." I started.

"This is MY house.  Im not going to tell Mom anything, and I doubt that you want to listen to her ranting either.  She's not going to find out.  So if you want to watch a nasty movie here, you can.  You can just relax, kick back, and just know that you can jack off and relieve a little stress without anyone walking in on you and lecturing and screaming at you for doing something that is completely natural, and something that they damn well do themselves."  Shayla said.

"Mom walked in on me one time, she didnt even knock.  When she realised what I was doing she said it was disgusting and she better not ever catch me doing it again.  Then she told me to put my fucking clothes on and slammed my door." I said.

"Mom is such a fucking prude.  You dont have to worry about anything like that while youre here.  Is there anything you want to know?  Any advice I can give you?  You can ask me whatever you want to, Im pretty sure Mom hasnt told you anything that she should have by now."

"Do you ever....you know..." I started

"Do I ever masturbate?" Shayla finished for me.

"Yeah." I said.

"Everyone does Mark.  I have a few toys that I play with from time to time.  Sometimes two or three times a day." Shayla laughed.

On the screen, the big breasted blonde was now on her knees, her head bobbing up and down as his cock slid in and out of her mouth.

"Do you ever do that?" I asked, motioning toward the screen.

"Yeah, I give blowjobs.  Its a pretty big turnon for me.  It just gets  my pussy really wet and then I really want to have sex." Shayla explained.

"How do you like to have sex?" I asked her.

"Well, a lot of the time I really like to be on top, so I can control how fast, how hard, and how deeply Im getting fucked.  But, if the guy is really good I like for him to be on top and just pump my pussy.  I like just about every position, but mostly I like to be on top.  It also leaves the guy's hands free to play with my titties, which really turns me on."  Shayla said.

"Lucky bastard..." I mumbled to myself, still watching the video on the screen in which the blonde was receiving the guy's load of cum all over her breasts.

Shayla laughed when she heard that.

"Um...I uh...I meant the guy on the movie...." I stuttered, my face reddening again.

"Its okay Mark.  Im flattered that you think Im attractive and that someone getting to fuck me is a lucky guy."

"You are?" I said, surprised that she wasnt mad.

"Of course I am.  Despite what many women will tell you, we like it when guys think we are hot and would love to fuck us.   A girl might act like she's offended, but deep down, she's loving the fact that someone finds her attractive and is thinking about what it would be like to be fucking her."  Shayla said.

"Really..." I said, thinking about a few of the hottest girls at school, and the way they always acted when they caught guys staring at them.

"Uh huh.  And I know you think Im pretty because I saw you staring at my ass in the hallway when we first got home.  And then gawking at my boobs through my nightgown here when I came back out and sat down on the couch."  Shayla giggled.

"Geez Shay, Im sorry...I just..." I stammered

"Its okay Mark.  Do you think that if I didnt want you to see that I would have started changing in the hall?  Or that I would wear such a see-through skimpy nightie if I didnt want to show off my boobs?" Shayla asked.

"I dont know" I said.

"Well, I did want you to look.  Im kind of an exhibitionist, but I had to be careful.  I couldnt just strip down naked in front of you because it would have been hard to pass off as normal activity if you werent interested.  But I could wear skimpy clothes and see through stuff to see how a sixteen year old sheltered guy would react to seeing his half naked sister.   When I saw you staring at my bare ass and then your eyes locking on my boobs while I was asking you about how things were with Mom, I knew you found me attractive in a way that was not just brother/sister affection."

"So why dont you take your clothes off then, if you like to show off." I said, wanting to see how far Shayla would go.  I was so horny right now, I knew it was my dick doing the talking at this point.  My hands were shaking and I could feel my heartbeat in my throat.

"Hmmmmm.  I could take off my clothes, but I would have to know how far you would be willing to go with this." Shayla said.

"How far are you willing to go with this?" I said.

"Ill do whatever you want me to. Ill make a man out of you tonight  if you want me to. Do you have a problem having sex with me knowing that Im your sister?" Shayla asked.

"No." I said.

"Youre sure now?  You know that NOONE can know about this, right?  I could get into some serious shit for this Mark.  Not only is this incest, but youre a minor as well.  Im looking at jailtime if anyone finds out about this, and you know that Mom is the kind of person that would push it.  You PROMISE to keep this between us?   I dont want to let mom ruin you by keeping you sheltered, so Im willing to let you fuck me whenever you want to, you know, to practice and be ready so that when you have a girlfriend, you can give her a great lay and have a reputation as a stud rather than someone who doesnt know what he's doing.   I dont like the word "slut", Mark, but I do love to fuck.   Im not like these girls around who act like its a chore for them to give a guy some pussy.  I love sex, and I like to get as much of it as I can.   So if you PROMISE to keep this a secret, Ill do whatever you want.  Ill show you everything you want to know." Shayla said.

"I promise Shay.  I dont want you to get into any trouble, and I know Mom would absolutely kill me for something like this.  I love you and I dont want you to go to jail, not after all the cool stuff you do for me and allow me to get away from Mom for a while.  Id go nuts if it werent for you." I said.

"All right then, its settled." Shayla said, and she got up and locked the front door, pulled the shades on the windows, and turned off the television.

"Okay Mark, come here." Shayla said, as she pushed one of the chairs in the dining room out into the living room, and pushed it up against the wall.

"Sit. Ill be right back." Shayla said.

I sat down in the chair, and waited as Shayla went to her room. 

"Okay, hands behind your back." Shayla said.

I put my hands back behind me, and I felt Shayla snap a pair of handcuffs on me, handcuffing me to the chair.

"What is this?" I asked.

"Just wait.  Its to keep you restrained while I work my magic.  For some reason, guys just have a lot of trouble keeping their hands to themselves until theyre allowed to touch me." Shayla teased.

Shayla went back to her room and came out with her stereo.  She set it on the kitchen table and popped a cd in and started it, and stood out in front of me as I sat in the chair.   Soon the Motley Crue song "She goes down" began playing, and Shayla began her sultry striptease for me.

As she sauntered around in front of me, she slowly began unbuttoning her nightgown while she gyrated her hips and tossed her head from side to side, flipping her gorgeous long brown hair left and right in the process.  As she unbuttoned the last button, she held the nightgown closed, and turned her back to me, holding the nightgown open and shaking her ass.

She dropped the nightgown to the floor, and slowly backed up to where I was sitting in the chair.  She bent over, and her ass was completely bare save for the small string of cloth that went right up her ass.  She rubbed her ass up against my hard cock, and ground her hips around in a circle, rubbing my cock with her ass.  

Shayla spun around showing off her perfect 34 D tits, her large nipples erect with excitement.  Shayla slowly straddled my aching cock, and sat on my lap, pressing her hands up against the wall behind me.  As she slowly ground her pantied pussy against my hard cock, my breath came in short, rapid breaths.   Shayla continued to grind against my cock, squeezing her tits together and breathing heavily as the song blared in the background.

My hands strained against the cuffs, and I wanted desperately to squeeze and fondle Shayla's perfect tits that were just inches from my face.  I now knew why she had restrained me.   Shayla reached down with one hand, and slid her thong to the side to reveal her perfectly shaved pussy as she ground her clit against the bulge in my sweats.

As the song came to an end, Shayla leaned down and kissed me hard on the mouth, sliding her tongue into my mouth and twisting around with mine.  I didnt really know what I was doing, I was just sort of mimicking what she was doing with her tongue, and apparently it was working.  Shayla broke the kiss to catch her breath.

"Oh wow Mark, youre a really good kisser.  You sure you havent done this before?" Shayla asked.

"Nope.  Youre my first kiss actually." I said.

"Hmmmm.  Its going to be a whole night of firsts for you then isnt it?  And all of them with your sister.  I wanna be the first to do everything with you Mark. " Shayla purred.

Shayla slid down the front of my body, and tucked her fingers inside the waistband of my sweats.

"Now, lets see what youve got to offer a lady." Shayla said, as she pulled my sweatpants off.

As my sweats came off, my hard, throbbing cock was finally released from its uncomfortable position.  Shayla gasped when she saw it for the first time.

"Wow Mark, youve got a huge cock!"  Shayla said.

"Really?" I asked, not knowing how I actually measured up against other guys. 

"Oh my God Mark.  Its got to be at least eight inches, and its so fuckin thick!  Oooh I cant wait to suck this gorgeous piece of meat!"  Shayla said.

Shayla moved back up towards me, and as she took my hard cock in her hand and began to stroke it, a couple pearls of pre-cum oozed out of the head of my cock.  She began licking and sucking on my balls as she slowly stroked the length of my hard cock, and then she moved up and in one swift motion she took the entire length of my cock down her throat.

"Uuuuhhnnnn!!!!" I cried, as I my hands strained against the cuffs that held me secured to the chair.  Id never felt anything that even came close to the feeling of my cock in Shayla's mouth.

My cock was throbbing so hard as Shayla sucked me and before I could even warn her, my cock began to jerk and spasm as I blew my virgin cum in her mouth and all over her lips and chin as she took my cock out of her mouth and jerked me off until my orgasm had subsided.

As my hips stopped bucking and my cock had finished covering my sister's mouth with cum, I realised that this was what Shay was talking about earlier, and I just knew I had disappointed her.

".....Sorry" I said, embarrassed and looking away from her. 

"Its okay, Mark.  It was just too much, too fast.  As you get used to what we're doing, that wont happen.  Im sure there's more where that came from right?"  Shayla said as she finished licking up my cum off of her fingers.

"Yeah." I said, still rather embarrassed at my lack of self control.

"Well, dont worry about it, because I wasnt going to let you out of that chair until you had cum in my mouth anyway.  Here, let me take those cuffs off of you before you hurt yourself.  Im surprised you didnt break my chair." Shayla laughed, as she unlocked the handcuffs. 

I looked at my wrists, and they were marked where the cuffs had dug into them.  As I rubbed them to get the circulation back into them, Shayla stood up and directed me to follow her into her bedroom.

I followed Shayla down the hallway, and as I watched her pretty ass bouncing with each step she took, my cock was once again at its full throbbing size by the time I got to her bedroom.  Shayla laid down on her bed, and she saw that my cock was already hard.

"Mmmmm.  This is why I LOVE younger guys.  You guys can blow your load, and 2 minutes later youre rock hard and ready to go again.  Enjoy it while it lasts little brother.  It doesnt last forever." Shayla said.

Shayla laid back and propped herself up against the headboard of her bed, and spread her legs, showing off her already glistening pussy.  She slowly rubbed her middle finger down her pussy lips, and back up again, stopping momentarily to play with her clit.

"Why dont you come here and lick my pussy for me Mark." Shayla purred.

"Okay." I said, and I crawled up onto the bed with her.

Shayla spread her pouting pussy lips for me, and rubbed her clit.

"Lick me right here babe.  If you wanna get me all hot and bothered, just suck and lick my clit.  You can lick my pussy, and that feels good too, but you gotta make sure you give my clit most of the attention if you wanna make me scream."

I started kissing my way up Shayla's inner thigh, slowly licking and sucking on her soft skin, trying to act like I knew what I was doing.  As I got nearer to her steamy pussy, I could feel her leg muscles  tighten, and her breath catching in anticipation of when my tongue would make contact with her dripping snatch.

I didnt really know what I was doing, so I pretty much just dove in.  I started to lick her clit like she had told me, and alternated between licking and sucking her joy buzzer, and Shayla began to writhe like a snake underneath me, moaning and gasping as my lips and tongue danced over her clit.

"Ooooh!! Oh! Ahhh yesssss.  Oh yeah Mark.  Oh God, just like that, OH!  Unnh!  Mmm!  Oooh yeah, dont stop...keep going....ooooh...oh!! Oh!! OHHHH!! Oh yeeaahh!!!   Im cumming!! IM CUMMING!!!  Ahhh!"   Shayla cried out in lust.

Shayla's hips were bucking and moving in circles, and she grabbed a fistful of my hair and buried my face in her hot pussy as her orgasm rocked her body.   I slid my tongue into her pussy, and as I did, I felt the wave of her cream flood over my tongue.  She tasted as sweet as sugar, and I couldnt get enough of her. 

Hearing Shayla screaming and moaning while I ate out her pussy was without a doubt the hottest thing I had ever done.  Something came over me and I was eating her pussy like it was the last chance I would ever have to taste her.    Shayla released her grip on my hair and began squeezing her tits and sucking on her nipples while my tongue continued its assault on her sopping cunt.

"Aaaahh!!  Oh yes!! Oh God Mark, it feels so goood!  Uh! Uhh!  Uhh!! Yeah!!  Oh!  Oh God!!  Oooooooooooh!!  Oh FUCK ME!  I need your cock right now Mark!!  Fuck me now!!" Shayla screamed.

I got up on my knees in front of her, and Shayla was like a woman possessed.  She slid towards me, lying down flat on her back, and immediately grabbed hold of my throbbing cock and guided it into her very wet, and very willing pussy.

The feeling of my cock sliding into Shayla's pussy for the first time was like nothing I had ever felt before.  I could feel my balls drawing up and I fought with every fiber of my being not to blow my load all over the inside of her pussy immediately.   I tried to think of something that would take my mind off of it, and my mind drifted to what would happen if Mom ever found out that I was fucking my own sister.   The thought horrified me, but it did the job.

I began to slowly pump Shayla's tight, wet pussy, sliding my cock as far inside her as I could and then pulling it all the way back out. 

"Ohhhhh Mark....your dick is sooo fucking good.  Oh yeah....Oooooh....thats it baby.  Fuck my pussy.  Its yours Mark.   Im here for you...ohh!! whenever you want to fuck....oh! Im yours...Oh yes!" Shayla whispered as I slowly slid my dick in and out of her pussy.

I leaned down and began to suck on Shayla's erect nipples, taking in as much of her gorgeous breast into my mouth as I could.  I flicked my tongue over her nipple in my mouth, and lightly nibbled on it as I squeezed and played with her other breast. 

"Oh yes Mark....youre a fast learner baby.  Ooooh..  Youre already better than some guys Ive laid.  Mmmmm!!  Oooh!!  Of course...Oh!! With that wonderful...Uh!! Huge cock of yours....Ohhhh!!  Oh!!  Youre not going to leave too many...Unnnh!!  women unsatisfied!!  Mmmmm!"

I began to quicken my pace now, as I got acclimated to the feel of Shayla's awesome pussy, and soon I was pounding her cunt faster and faster, burying my cock to the hilt and bouncing my balls off of her asshole.  

"Oooooooohhhh!!  Oh yeah!!  Yeah baby!! Fuck me, fuck my pussy baby!!  Ahh!  Ooooh Mark!!  I want you to cum inside me!  I want to feel you cum!" Shayla cried.

Hearing Shayla talking dirty to me like that, the feel of her tits in my hands, and her pussy stroking my cock, it was soon too much for anything to take my mind off of it.  Cum was boiling in my balls, and nothing was going to hold it back.   I felt my cock begin to spasm and throb again as I shot stream after stream of hot sticky cum into my sister's pussy. 

"Uuuunnnghh!!  Oh! Oh Shayla!!  Your pussy feels soo fucking good!!  Im gonna cummmm!!"  I cried as my orgasm hit me so hard I nearly passed out.

"Ohh yeah.  Cum for me baby!" Shayla cried, her hands gripping my ass and burying my cock as deep as it would go into her body.

As the throbbing in my cock subsided, I collapsed on top of Shayla, feeling her rock hard nipples pressing into my chest.

Shayla was sucking on my neck, and running her hands over my back.

"Youre a man now Mark." Shayla whispered into my ear, slowly grinding her hips against mine, my cock still buried in her pussy.

Shayla rolled over on top of me, and began kissing me deeply, her tongue dancing around mine.   She sat up, and squeezed her tits together and began licking her nipples as she worked her pussy up and down my cock, which was rapidly returning to its rock hard form.

"Oh yeah. Yeah.  Oh God Mark, youre a great lover!  I cant believe how fast you get it up again after cumming!" Shayla moaned as she began to fuck me at a steady pace.

I grabbed two handfuls of Shayla's ass, squeezing and massaging her incredible ass as she bounced up and down on my dick.  The harder I squeezed her ass, the hotter she got.  Shayla was getting hotter and hotter and I spread her ass cheeks apart and began thrusting her hips down onto mine.  My fingers wandered around to rub and probe her tight little asshole, and Shayla was rapidly approaching another orgasm.

"Oh!! Oh Mark!  Ah!  Ooooooh baby Im gonna....Im gonna cummmm!!!" Shayla screamed as her pussy juices flooded down over my cock.

I kept up a slow, steady pace of sliding my cock in and out of Shayla's pussy, all the while playing with her asshole. 

"Mmmmmm.....Ohhhhhh.  That feels so good.  Do you want my ass, Mark?"  Shayla asked in a sultry voice.

"Yeah." I said, still playing with her tight little hole.

Shayla slid off of me, and got on her knees in front of me, her pretty ass on display just for me.

"Fuck my ass, Mark.  I wanna give you everything.  I wanna feel your cock throbbing in my ass." Shayla moaned.

I got into position behind her, and pressed my wet and sticky cock up against Shayla's asshole.  I slowly applied more and more pressure, and soon my cock pushed through and I couldnt believe how tight it was.  I thought that Shayla's pussy was tight and felt so good, but her ass was even better. 

"Oooooh!!  Ohh...easy!!  Easy!  Ahhhhh!!  Oh yeah Mark!!  Ohhhhhhhhh!!" Shayla screamed as I began to slowly fuck her asshole. 

Shayla grabbed my hand and moved it around her waist and placed it on her clit, and I began to rub and play with her joy buzzer as my cock slid in and out of her ass.  

"Ahhh!  Ahhhhhh!!  Oh God!! Oh God Mark!!  Dont stop....dont stop...Dont stop fucking me!!!  Oh God Mark!!  Im gonna cum again!!"  Shayla cried.

As Shayla's orgasm hit her, I felt her asshole tighten and spasm, sending sensations through my cock that I just could not withstand.   Before I could even begin to try to stop it, my cum shot from my cock, blowing my load inside her incredibly tight ass.

"Ahhgghh!! Oh Shay!  Im cumming!!!" I screamed as I blew my cum in her ass.

"Oh yeah Mark!  Gimme your cum!!" Shayla cried as she continued to fuck my cock with her ass, clenching her ass and bucking against me until my orgasm had subsided.

My head was spinning, and as I pulled my cock out of Shayla's ass, she moaned again and then turned around to kiss me deeply.  She pulled me down onto the bed with her, laying her head on my chest, listening to the pounding of my heartbeat.

"Wow Mark.  I had no idea that you would be this good." Shayla said as she ran her hands over my chest and stomach.

"Me neither" I said.

"So, how did you like your lesson?" Shayla asked.

"I dont really think I got it all the first time.  You might have to show me again." I teased.

"Oooh.  Youre on babe. Like I told you, I love sex. I love to get fucked and Im not ashamed to admit it. And....I love you.  So anytime you need some pussy, you know that you always have a place you can come and get laid.  No way those hardons of yours should go to waste through jacking off, when I could be playing with it."  Shayla purred.

I ran my hands over Shayla's gorgeous breasts, squeezing and playing with them.

"Id much rather play with these and have you play with my cock than be by myself too." I said.

"Mmmm.  Im glad you like them.  I absolutely LOVE your cock.  The great thing is, youre only going to get better.  You were great and this was just your first time.  There's still a lot that I can show you too." Shayla said.

"Oh yeah, like what?" I asked.

"Hmmmm.  Come with me, and Ill show you." Shayla said as she headed toward the bathroom.

"You ever see any shower scenes, lil brother?" Shayla asked.

"A couple." I said.

"Well, youve never seen anything like the one that WE are gonna have." Shayla purred.

As I got up to follow Shayla into the bathroom, I knew that this was without a doubt going to be the best birthday of my entire life.   Shayla had given herself to me, a gorgeous woman to fuck whenever I wanted, to perform any sexual fantasy I desired.   How can you beat that?
