Chapter 3
Lesley and Sarah arrived and settled into the spare bedroom. Their presence didn't stop Robin and Billy. The youngsters had fallen into a set routine involving acts of forbidden love and a dirty word. Incest.
Every night, when she was certain everyone in the house was asleep, Robin tiptoed to Billy's room, which was situated at the far end of the hall. Gradually they began experimenting with oral sex, but they both knew it was only a matter of time before they would go all the way.
One night when Robin suggested blowing him, Billy seemed nervous.
"But you love when I suck your cock!" she said.
"Yeah, but I was wondering about Sarah. She's been hanging around me a lot. Do you suppose she's spying on us?"
Robin glowered at the mention of their cousin's name.
"I don't care if she is. I hate her. I wish Aunt Lesley would make up with Uncle Pete and go home."
"I think they'll be here all summer."
The little blonde knelt in front of her brother and pressed her cheek against his crotch. She began unzipping his fly.
"Does that mean we shouldn't have our fun? Just because they're around?"
"I think Sarah might be wise to what we're doing," Billy said.
"Well, she can just go fuck herself. She's just jealous because she doesn't have a brother."
Billy toyed with Robin's hair. "Yeah, but what if she tells?"
"I don't think she'd do that. First of all, she knows she'd be in big trouble with you," Robin said.
"Yeah, that's true. Pull my jeans all the way down!"
"I will in a minute. Mmmmm, I love sucking your cock!"
"Let's get into bed."
"God, your cock tastes good. Did you just pee? I taste pee."
"Jesus, Sis, you're a nut, you know it?"
When he pushed her away and began removing his jeans, she moved behind him and rubbed her tits into his back.
"Hey, what are you doing?" he said.
"Getting you good and hot."
Billy chuckled. "I think Sarah wants me to fuck her."
"Fuck Sarah. Let her find her own boyfriend."
The horny little blonde began undressing.
"She's just my cousin," Billy teased. "It's not as big a sin fucking your cousin as it is fucking your sister."
"She's just a kid. I'll bet she doesn't know the score. She's just a tease."
"She's only a year younger than you."
"Well, anyway, I'll bet she's just a cock-tease."
"Maybe."
Billy still had his socks on. He seemed to be stalling. Robin was naked now and she took her brother's hand and held it against her chest.
"Feel how my heart is beating," she said. "I'm real horny."
He grinned. "You're always horny!"
"When I'm real horny, you know what I want?"
"Aw, Sis, we can't!"
"Why not? You know you want it. We both do."
"Sucking is one thing and feeling each other up, but, Jesus, we can't go all the way."
"But we both want it!" the teenage sexpot whispered, running her hands over his chest.
"Aw, Jesus!"
A few minutes later, when the youngsters were lying naked in each other's arms, Robin took Billy's cock into her fist and squeezed it.
"It's so nice and hard!" she said, gently working her fingers around his sensitive cock-head.
"Hell, it's always hard. I always have a hard-on."
"Stop bragging."
"It's true. Jesus, that feels good. I really need to get off!"
"You just did last night."
She fondled his balls as she lowered her mouth to his cock.
"Yeah, but I need it again. Take my cock into your mouth. All the way!"
The teenage blonde knew exactly what he liked. She knew he liked when she fluttered her tongue up and down his cock-shaft and when she poked it into his piss-slit.
She had taken to cock-sucking quickly. She had even learned how to take Billy's cock into her throat without gagging.
"Jesus, Sis, you're a damn good cock-sucker!" he moaned. "That feels good, what you're doing with your tongue!"
"It'll feel even better in my pussy!"
"Don't bug me. I told you. We can't go all the way! This is bad enough!"
"Bad?" she teased. "I thought you liked it!"
"You know what I mean. Do that again. Lick my balls!"
The horny little blonde was dying to lose her cherry. She knew eventually she'd have her way. Billy was so horny. And the hornier he got, the more likely he was to go all the way with her.
Maybe he's afraid to lose his cherry, she thought as she flicked her tongue around and around the flared rim of his cock-head.
"And it's not that I'm afraid," Billy said suddenly.
"Hey, I was just thinking maybe you're scared."
"Well, I'm not. I almost did it a few times. One of the girls in my class let me almost put my cock in!"
"Almost put it in!" Robin mimicked. "That's like being a little pregnant!"
"Hey, are you really taking the pill?"
"Sure. I told you. I'm safe. There's nothing to worry about!"
Now the horny teenager spit her brother's prick out and gathered saliva in her mouth. Then she slowly wet his cock-head down with saliva and just as slowly licked it up again.
She made a circle of her moist lips and rubbed them over the length of his fuck-pole. She nibbled and sucked and licked the entire surface of his cock-shaft and when it twitched violently she buried her face against his balls.
"Yeah, lick my balls, Sis!" Billy said excitedly.
Robin liked the taste of his cock-skin and enjoyed taking tendrils of cock-hair between her teeth. Still, as much as she loved sucking his cock, she wanted more. She wanted to become a woman. She wanted to get fucked.
If I get him horny enough, she thought, he'll fuck me. If I get him horny and then refuse to finish him off he'll have to fuck me.
Now she took his balls into her mouth momentarily. Billy grabbed hold of her hair, digging his fingers into her golden curls.
"Holy shit!' he howled when she flicked her tongue into his ass-crack.
"I never did that before," she said, stabbing her tongue-tip against his shitter.
"That's fantastic!"
She held his prick and forced her tongue into his ass.
"Mmmmm," she mumbled happily.
"Stick your whole tongue in there!"
"I can't. It won't fit!"
"Jesus, it's incredible!"
"How about my finger? Should I stick my finger in there?"
"Yeah, stick your finger in."
She capped her lips around his cock-head and gently inserted her little finger into his brownie. He groaned when she began sucking and fingering, sucking and fingering.
"That's great, Sis!" he said, clutching her hair and opening and closing his legs around her head. "Where'd you learn that?"
"Nowhere. I just like to let myself go and do whatever comes to mind. I bet I'll be a great fuck if I can just get someone to take my cherry!"
Billy snickered. "Okay, okay, I get the message."
She gurgled softly as she fluttered her pointed tongue over his cock and finger-fucked his asshole. At intervals she slid his meaty prick into her throat and held it there.
She loved the texture and taste of his cock. She held the base of his cock-shaft between two fingers as she gently and lovingly licked his cock-knob.
Her own ripe body was on fire. She was determined to make him fuck her. She knew he wanted to. What was the harm? They were doing everything but fucking.
She wondered if her mother still sucked her father's cock. Sometimes she heard her parents fighting and sometimes her mother yelled that she wasn't getting enough. Robin was certain that meant her mother wasn't getting fucked often enough. She felt sorry for their mother, and her father too. It must be dreary to sleep with the same person year after year.
"Hey, you look cute with your mouth full of cock!" Billy said suddenly.
"Stop jerking around like that or I'll take my finger out of your asshole!"
"Take it out. I'm gonna come if you keep doing that!"
The teenage girl knew that boys Billy's age could get hard again soon after coming.
"I wouldn't mind taking a cum-load in my mouth."
She didn't say that she had every intention of bringing his prick up again and making him fuck her.
"Yeah? You don't mind?" Billy's voice was husky and eager.
"Yeah, come on, let it out. Mmmmm, I love the taste of jism!"
The horny little blonde sucked hard on his pulsating prick and salivated at the prospect of taking a cum-load in her mouth.
She remembered the first time they had oral sex. First she sucked Billy off and then he went down on her. It had been the most exciting hour of her life. She found she loved the taste of come and adored sucking cock.
"Oh, fuck, Sis, I'm gonna blast!" Billy hissed now as his thick spunk gushed into her mouth.
His load seemed endless to the inexperienced girl. Wad after wad of jism flew into her greedily sucking mouth. She swallowed as quickly as she could, but eventually some of it oozed out of the corners of her mouth and dribbled down her chin.
"Yummy!" she giggled, coaxing the last few drops of jizz from his piss-slit.
"Jesus, what a come I had!" Billy said, falling back exhausted against the pillows.
Robin held his flaccid cock against her cheek and kissed it tenderly. She fondled his balls. They were empty now and somehow vulnerable. She kissed them.
"I guess I give a pretty good blow-job!" she said, lapping her tongue around his shrunken cock-head.
"You sure do, Sis. You give a hell of a blow-job!"
Robin giggled. "Wait until we fuck. I'm going to be a terrific lay!"
"Are you starting that again? I can't take your cherry!"
"You're cherry too. We're both cherry. I'll take yours if you take mine!"
"I just came. Forget it." The young girl took a deep breath. "If you won't fuck me, I'll give it to someone else." "You wouldn't."
"Sure I would. Having a cherry is a liability nowadays. If you won't fuck me, I'll find plenty of guys who will!"
Billy frowned. "Guys don't want cherries. They're messy!"
"Mine won't be. I broke it long ago, so I know it won't hurt and I won't bleed."
"Yeah?"
"Getting interested?" "Maybe."
She hugged him. "I'm all broken in, big brother. And I'm real horny." She stretched out on her side and lewdly touched herself. "Mmmmm, I'm so horny I just might jerk off if you won't do what I want."
Out of the corner of her eyes she saw his cock twitching. She continued touching herself with one hand and tugging on her nipples with the other.
Billy stare at her with hot eyes. He was dying to fuck her and had been for years. He constantly fantasized about getting laid, but something always stopped him from going all the way with Robin. She was his kid sister and it wasn't right. But how long could a guy resist?
Actually Billy was obsessed with sex. He loved women of all ages. Sarah made him horny and even his mother and his aunt made his balls ache. Sometimes he thought he was a sex maniac. Sometimes he thought if he didn't lost his cherry he'd wear his cock out masturbating it.
"Billy," Robin cooed, aware of his conflict. "I'm jerking off like crazy, but it's not enough. At least touch my pussy and see how hot and wet it is. And you can jerk me off better than I can do it myself."
His cock gave a mighty lurch when he reached over and slipped his fingers around her slick cunt. She took his cock in her fist as he rubbed her clit.
She waited a few minutes. She waited until his cock was very hard again and until his eyes were glazed. She encouraged him to stick two fingers into her cunt and wriggle them around. Then she rolled onto her back, spread her legs and wailed.
"Fuck me, please! I need it so bad!"
Billy was frightened someone might hear. He crawled over her, clutching his prick.
"Sssshhhh," he said, jabbing his cock against her juicy pussy-slit.
The little blonde quickly wrapped her legs around his back.
"Put it in quick!" she hissed.
His face down, a lock of hair over one eye, he pushed the head of his cock into her virgin cunt.
"Does it hurt?" he said.
"No, I told you. That thing broke long ago. Oooohhhh, Billy, that feels so good!"
She held her breath as his cock slowly slithered into her cunt. So this is what it feels like to fuck! She had waited so long and it was finally happening.
In a matter of moments his teenage cock was buried in her writhing, squeezing fuck-tunnel. Her velvety-skinned thighs hugged his waist and she pulled his face down to her tits.
"Kiss my tits," she sighed, pumping her ass off the bed to meet his thrusts. "Oooohhh, that feels so good!"
With a grunt, Billy began thrusting more forcefully into the grasping wetness of her virgin cunt. Each stroke made the little blonde gasp.
"Fuck me harder, Billy!" she squealed. "It doesn't hurt at all. I love it. Don't you?"
"Yeah, I love it!" he panted.
She clutched his ass and pulled him against her, forcing his cock to penetrate her more deeply.
"We're not virgins anymore!" she cried.
"I know. Jesus, I never felt anything like it before. I think my cock's growing! Do you feel it?"
"Yes, it's jumping around inside me. Every time you shove your cock in it feels like it's gonna explode!"
"Are you gonna come soon?"
"Yeah, any minute."
"I'll wait for you."
"Oh, Billy, it's coming!"
The little blonde floated on a sea of ecstasy as she came. She wrapped her arms around her brother's neck and bit his ear as the wonderful sensations surged through her.
She was climbing toward a second orgasm when Billy began fucking her so fast she thought he might split her in two.
"Come in me!" she whimpered. "Oh, Billy, come in me!"
He drilled his hard teenage cock into her. He fastened his lips to one of her tits and sucked it while he emptied his balls in her cunt.
He pounded away as he filled her insides with thick warm jism and she felt her pussy squeeze shut around his spurting cock.
Later, when they were resting, Robin took Billy's hand and kissed it.
"Now neither of us has a cherry! We'll never forget tonight. Oh, Billy, let's do it again!"
