Introduction:

No matter if they're brother and sister, or not... teenagers ALWAYS have a desire to learn more about sex. in this story, the siblings wind up proving their love for each other...
Cassidy had walked in front of Bill for the third time. It was Saturday and she was doing her assigned duty, dusting and vacuuming.
Bill, on the other hand, was trying to watch a baseball game on TV instead of cleaning the bathrooms and taking the garbage to curb for the large container.

Cass was wearing a t-shirt and panties, as she always did on weekends around the house. It had been her standard dress since she was a toddler.
Bill wore nothing but some cut-off sweat pants which reached half way to his knees.

As she began the back and forth pattern of cleaning the open carpet area, Cass’ sixteen year-old body was blocking his view of the game. Bill picked up a rubber band and waited to choose just the right target. When she turned her back, he drew it tight and popped her pretty little ass on the right cheek.

“OUCH! Damn you, Billy!” The handle of the vacuum cleaner hit the floor and she leapt for her brother.
Billy, being just less than two years older, was a little quicker, gaining his feet and jumping over the back of the couch. He ran to the back door, knowing Cass wouldn’t follow him outside in her skimpy clothing.

“Shame on you, Cass, you’re not supposed to cuss. I might have to tell on you.”
That was enough for her to keep on his tail as he ran out the door, trying to close it behind him. This time, she was fast enough to catch the door and slammed it behind her as she chased Bill across the yard.

“I’m not gonna just cuss you, Billy Parker. When I catch you I’m gonna kill you! That rubber band hurt, by God.” They circled two trees and the dog kennel, setting Bitsy into a barking mood.
When Bill glanced back at Cass, he didn’t see the garden hose. His foot caught it and he flew ten feet before landing in the grass.

About the same time he stopped rolling, Cass jumped in the middle of his back, digging her fingers into his ribs. She knew he couldn’t stand being tickled and decided to take full advantage of the fact.
Bill bucked and wiggled. He would push her hands away, but he would never hurt her.

As the teenagers wrestled in the grass, Bill would pull at the top of her panties, thinking she’d give up and run back into the house. Every time he’d jerk on them, she’d just pull them back up and resume tickling. He finally managed to get her on her back and pinned her arms to the ground.

Both of them were laughing hard, as they’d done many, many times. He reached back to her knees, where he squeezed just above her kneecaps, in that area where it’s hard to distinguish between tickle and pain. “You’re not supposed to be outside in your underwear, shame on you.”

Kicking her slim legs, she alternated between getting her knees out of his grasp and trying to pound him in the back with them. During another outburst of laughter, Cass warned him to get off her, “HAHAHA! QUIT! You better get off me, I’m about to pee my pants!”

“Tell you what, sis, I’ll let you up if you promise not to chase me. You can go pee, but when you get the vacuuming done, you clean the bathrooms, too. Deal?” Cass was about to protest, but she needed to pee… really bad. They had always kept their word, so she agreed to the terms, but began planning a… ‘I’ll get you back this evening’.

All their young lives the Parker children had been very good at learning manners, respecting others and caring for each other. Neither of the kids could remember having a serious argument with the other, although the mischief was always a part of their personalities.

Nora Parker worked six days a week as a waitress at a local diner. Through her years of dedication to the business, she had progressed to very good wages and wonderful tips from her faithful customers. Nora probably brought more money home than any two other employees, the exception being Lee Wang, the owner.

Often, Bill and Cassidy would walk the four blocks to have supper with their mom, but she never worried if they didn’t come. She had always been comfortable that they would be safe at home. On school nights, they would both be in their beds asleep when she got home from her late shift.

At thirty-two, Nora was very attractive, but declined many invitations to go out with men, some of whom she’d even known for a long while. She wasn’t stupid, however. About once a week, when she stayed after work, Lee Wang provided a nice ‘bonus’ of $200 for ten minutes in her pussy. His wife never knew…

It was eight-thirty and Cassidy had finished her chores, and Bill’s. At least three more hours before her mother came home, it was time to put her plan into action…

“Billy! Can you come help me? I’m in Mom’s room!” She slid under the bed and got ready. When Bill came into the room, she called out, “I’m under the bed and this box is stuck. If you can reach under here and get the other handle, I think I can push as you pull and we can get it out.”

His arm stretched under the bed and suddenly, his wrist was caught on something. Cassidy had clasped one end of handcuffs on him, the other end was clamped to the bedsprings.
“What the fuck?”

Cassidy slid out the other side and said, “Awmmm… I’m gonna tell mom what you just said. She’s gonna have a fit when she gets home, anyway. You’re gonna be in so much, BIG trouble.”

“What’re you talking about? You’re the one who’s gonna get in trouble for trapping me like this. Besides, when I do get loose, I’m gonna kick your ass, girl.” His other hand was under the bed, trying to figure out how to release himself. Cassidy slipped up behind him and jerked his loose fitting shorts down to his feet.

The second she laid eyes on his rising cock, her mouth dropped open. It had never occurred to her that IT would be on display. She had only thought of him being bare assed when Nora got home. Now she didn’t know what to do next.

The cusswords were flying from Bill’s mouth but she was paying no attention to him. She did see him grab the waistband of his shorts, so she jerked them completely off and pitched them onto the bed. Finally, she told him she’d make a deal.

“I’ll unlock the cuffs, but you do all the chores next Saturday, and nobody tells Mom anything about what happened today,” she gently pinched the head of his dick and added, “or tonight.” He agreed, she turned him loose and they both went to the living room… The Mentalist was on TV.

“I wish I could figure out what people were thinking. If I were Patrick Jane, I’d want to know if Teresa really liked me or not.”

“Why?”

“Because, if she really did like me, I’d try to get in her panties.”

“Whaaaaaat?”

“Yeah, if I were a mentalist, I’d figure out who would put out and who wouldn’t. That way, I’d be able to … fuck… girls all the time.”

“Billy, you better be careful, if Mom ever hears you talk like that, she’ll lock you in your room for ten years.”

Bill looked at his sister’s eyes and smile. He slid his shorts down, exposing himself to her, on purpose this time, “C’mon, Cass, let’s fuck. You and me. It’ll be fun.”

Again, Cass couldn’t take her eyes off the stiff shaft, “Billyyyyy! We can’t….”

“Why? I never tell your secrets. You never tell mine. We can get naked and find out more about each other. Then we can fuck. I mean real fucking. C’mon, sis, how ‘bout it? We both need to know how to do it and we can teach each other. I know a website called XNXX where we can learn a bunch, too. C’mon, let’s do it.”

Cassidy stared at the first grown cock she’d ever seen. Every time she blinked, it seemed as if it grew longer and fatter. In addition, she discovered her hand was on her own mound, her fingers seeking her slit, through the fabric of her underwear.

“But, Billy, you’re my brother. I don’t think brothers are supposed to…”

As she talked, Billy got to his feet and walked across the cushions, his dick in his hand, “Look how hard it is, Cass. If I don’t get some relief, my balls will start aching and infections have been known to set in. If you don’t want me to fuck you, would you suck me off?”

“Billy, I never said I didn’t WANT to fu… have sex with you. I said I didn’t.. think.. we…”

Bill dropped to his knees, “Then first, take off your pants and let me see you. Let me touch your pussy. I promise not to hurt you or do anything if you tell me ‘no’.
She slipped out of her panties and spread her legs, slightly.

With his hard-on in his right hand, Bill reached out with his left and began a light massage on her twat, trying to concentrate on her clit, like he’d seen online, “Does that feel good? The girls on the computer seem to love it… but if you let me lick you, down there, it’s supposed to be fucktastic.”

“God, yes it feels good, but I still don’t think we… oh, that place, right there. Ugh, yeah, right there. Ohhhh, that feels reeeeally good. Are you serious about licking me? Right where I pee?”

“Cass, there’s so much shit on the internet, you wouldn’t believe it. I’ve watched girls take two dicks in their pussy and one up their asshole, all at the same time,” he moved off the couch and stuck his head close to her cunt, which was beginning to get wet with her own juices.

“I saw a guy, once with a double dick. He was fucking both holes at the same time. Wow, Sis… your pussy is a lot prettier than a bunch of those whores online.” As he moved his head down, Cassidy instinctively widened the spread between her legs. Bill’s mouth opened and his tongue extended.

Cassidy gasped at the feel of slick tongue on her slit, “Billyyyyyyy… Oh, God that feels awesome! Oh, yes, yes, yes… ugnh… yeahhhh.. Oh, yeahhhh.” Nature was taking control of her body’s desires. Her hips began rising to Bill’s mouth in rhythm with his ministrations.

Less than a minute had passed when she began to feel the tingling within her. At first, she thought she needed to pee, but this was different. One hand went to the back of her brother’s head, pressing it into her virginity. Her other hand slid under her t-shirt and started rubbing her nipples which, at the age of thirteen, stuck out farther than the rest of her breasts.

Another minute of the lapping tongue brought Cassidy to her first orgasm, “OH MY GOD, BILLYYYYYY!! OH MY GODDDDDD!! WHAT’S HAPPENING? OH, SHIIIIIIIIITT! I’MMM… OH, GOD, OH, GOD, OH, GGGGGG, GGGGG, GODDDDDDDD!!!!! DAMMIT!!”

Bill was quite pleased that he had caused Cassidy to cum for her very first time, “Wow, Sis. You just soaked my face with pussy juice. Awesome! Man! It tastes really good, too. If you liked that as much as I did, I’ll be happy to eat your cunt anytime.”

Cassidy was breathing hard, “Juice? Cunt? What the hell did you do to me, Billy?”
Bill stood and pulled her t-shirt over her head, “C’mon, there’s a video on XNXX I want to show you.”

The naked teenagers ran upstairs to Bill’s room. The porn site was bookmarked and within seconds, they were watching women masturbating themselves, to the point their orgasms made juices literally flow from their vaginas. Glancing at his sister, Bill noted that she was playing with herself.

“Now look at this one,” Bill switched to another video, “This one reminds me of us, Cass.” The brother and sister were wrestling over a remote control and giggling each time one would touch the other’s private parts. Cassidy’s mouth hung open as she watched the sister swallow her brother’s cock.

“How can she get that much in her mouth?”
Bill explained that it took a lot of practice to be able to ‘deep throat’ a long dick, “But we can practice a lot, if you want to,” he smiled and winked. Within minutes, Cassidy had watched the sister suck the cock and get fucked in four or five positions.

Bill clicked off the website and told her, “There’s got to be a million different videos on here and tons of dirty stories. Billions of pictures, too… women, men, gays, dicks, pussies, titties, you name it. You can come watch ‘em any time. This site is safe from viruses, too… now can we fuck?”

“Ummm… let me go pee. Then we can try it… I guess.” Bill offered to accompany her to the bathroom and dry her hairless bottom for her, but she told him she needed to think about things a little, “Will you let me suck on you when I get back? I think I’d like to try it.”

“Oh, fuck, yeah! I’ll be right here on the bed with my dick flying high.” Cassidy returned and climbed between Bill’s legs, “I just looked at the clock, Mom will be home in an hour and a half. I hope this won’t take long.”

It took a little longer than bill desired. Her hands and eyes examined every crease and hair on his testicles. Every vein in his six inch penis was traced up and down ny her probing fingers, every fold in his skin was stretched smooth… then pinched back into place.

As pre-cum started forming on his piss slit, Cassidy began licking it clean, followed by her young, tender lips sliding the shaft between them.….. Bill was so turned on by watching her go down on him, he came in less than two minutes. She swallowed all she could, but lost a little bit.

“Sorry, Billy, now there’s a mess on your sheet. Maybe Mom won’t notice.” Bill explained that he’d been jacking off for three years and his sheets were always soiled, “If you let me fuck you, though, we better put a couple towels under you. There can be a little blood the first time, when your cherry breaks.”

“My cherry? Will it hurt me? You have never hurt me in our whole life.”

Bill had read many of the sex stories and knew just what to say, “Your hymen is also called a cherry. It’s a thin membrane inside you and when a dick pokes through it, it breaks, turning you into a woman, instead of just a girl. It usually hurts a little the first time, but after two or three times, women like it just as good as men…. NOW can we fuck?”

“You’ve never done it, before, either… right?”
Bill shook his head and reached for her legs. He began rubbing the inside of her thighs , working her legs apart and approaching her pussy, “C’mon, Cass… how many times are you gonna make me ask? You know we’re gonna do it. How do you want to start?”

She crawled beside him and lay on her back, “I want to try every way the girl in the video got fu… fucked. First, just lay down on me and rub your dick against my pussy. We’ll probably only have time to do it once before Mom gets here, so I want my cherry busted and your cum inside me.”

“When was your last period?”
“It was finished day before yesterday.”
“Good, you shouldn’t be laying eggs, yet, so I won’t get you pregnant.”
Cassidy started to rise when she heard the word ‘pregnant’, but relaxed when her brother kissed her and said, “Don’t worry, Cass, I love you.”

It took all of three seconds for Bill to jump from the bed and retrieve towels from the bathroom. He helped slip them under her ass and crawled over her flat body. He placed his cock on her mound and hunched back and forth. In this position, she was delighted to discover her clit was being rubbed with every movement.

Bill couldn’t last long enough for her to reach an orgasm. It seemed they only got started when he covered her abdomen with warm, sticky sperm, “Well, I hope I can stay hard after shooting all that. I want to put my peter in you so bad I can’t stand it, Sis. I’ll get you a wash rag.”

Fortunately, youth and virility were on his side. Bill returned and washed the mess from his sister’s belly and pussy mound. The more he ‘cleaned’, the wider her legs spread, “I’m ready whenever you are, Billy.”

Again, he examined her cunt, spreading her labia and giving them a good licking. When he thought she was wet enough, he rose into position and pulled his dick up and down between her pussy lips. When her hole began to open, slightly, Bill pushed his hardness inside, sliding in far enough that her cherry gave way to the determined shaft.

With one more thrust, he was seated against her pubis. To her credit, Cassidy had caught her breath but she never cried out nor complained of the pain. She placed a hand on each side of her brother’s face and drew him to her face for a kiss. When they broke away, she closed her eyes and told him, “Now fuck me, Billy… fuck me with all you got.”

***********

Nora Parker arrived home about 11:30pm. Surprised that her children weren’t up to greet her, as they usually did on Saturday nights, she made her way up the stairway. Cassidy wasn’t in her room… she heard soft snoring coming from her son’s room. Slowly opening his door, her eyes were met with a sight that brought back fond memories.

Cassidy was sleeping, naked, in her brother’s arms. Bill’s young penis was hard, pressing into his sister’s back… it was just like Nora and her brother, Will, used to sleep after several rounds of teenaged sex. It was a shame Will was killed in action. He played with Bill when the boy was just learning to walk, but he never even got to meet his daughter.
