Fight Club

He was lying on his parents bed watching Fight Club with his 18 year old sister. He was only a year older than her and they had always been close. They had the same taste in everything. They loved the same music and the same movies. They even had the same friends at school.

He had wanted to watch the movie on their widescreen downstairs, but it had been broken since last Thursday. Brenda was the one who suggested they watch it in their parents room since they were both off on business trips.

"I've always wanted to fight someone," she admitted as Brad Pitt and Edward Norton began fighting for the first time in the movie. Greg laughed. His sister was 5'2" and probably barely weighed 100 pounds.

"You would get your ass kicked as he studied her body. She had a nice ace and great tits, but she wasn't exactly muscly. And he told her so.

"I've got more muscle than you'd think," she protested. "I'm wiry. Plus I'm scrappy and I'd totally fight dirty. I think I could win a fight."

"Maybe against another girl," he acceded. "But any guy could take you."

"Oh really?" she asked. He knew that she was gonna be pissed. Brenda hated when people told her she couldn't do something.

"Yep." he taunted her. She was so easy to get riled up. "It's just biology."

She sat up and looked at his body pointedly. "Okay Mr. Muscle Man. I bet I could take you." Greg just laughed. A lot of people mistook him for some scrawny wimp, but he was stronger than he looked.

"Yeah right." he snorted. Before he could turn back to the movie, Brenda jumped on him. He hadn't expected her attack and she managed to pin him on the bed holding his arms above his head with her knees.

She looked down at him smugly. But his eyes were a little bit lower. Her pajama shorts gapped in the crotch and he could see bits of her thong. He swallowed loudly.

"Nice view?" she asks joking. Greg blushed hotly. While she was still complacent, he flipped her over. He managed to capture both of her tiny wrists and was holding them above her head in one hand.

He looked down at the view of his sexy young sister below him. Her tank top ridden up her body and he could her stomach up to just below her bra. He looked down at her helpless form and couldn't help but notice some things. Her breathing was labored and it caused her chest to heave up and down. He was transfixed by her chest. Without even realizing it, his cock began to harden. Her eyes widened and she looked down to where his hard cock was becoming visible against his pjs. She must be able to feel it.

Greg was mortified. He rolled off of his sister refusing to look in her direction.

"This is stupid," he lectured her. "Let's just watch the movie." He stares at the tv his mind racing. She obviously felt his arousal. What if she told someone that he had gotten hard because of her.

Out of nowhere, Brenda leapt on him again. She sat on his stomach. Greg didn't try to resist.

"I'm too tired to play stupid games. Get off Brenda." he tried to push her off gently but she wouldn't budge. She started bouncing up and down on his stomach like they did when the used to play "Horsey".

"You're just scared because you know I can take you." she accused him.

"I'm serious Brenda, I'm tired let's just watch the movie." By now her wriggling has given him a full on erection but she luckily she couldn't feel it because she was sitting on his stomach. Greg just wanted to get out of the situation with as little embarrassment as possible. Unfortunately, one of his lackluster shoves pushed Brenda back and she felt his cock poking her in the ass.

"Fine then," she said pouting. She pushed her ass backwards until his prick was lodged firmly in her crack. She could feel the light pressure against her mound but her body ached for more. "I guess I'll just have to tickle you. He was her brother and she knew all his most ticklish spots. He was writhing against the bed trying to get away from her she clamped her thighs around him. One particular buck of his caused his cock to slip between their bodies. She could feel the outline of it running against her lips. Greg moaned, and immediately looked horrified. His hands began to push at her thighs.

"We shouldn't be doing this, it's wrong," his eyes were shut tight.

"Do what?" Brenda asked feigning innocence. She abandoned any pretense of play fighting, rocking her hips against him.

"We're just rough housing, no big deal." Her fingers still lightly trickled over his chest no longer tickling but caressing. He looked into her eyes and the lustful look she was giving was too much to bear.

"I guess we can rough house some more." he sighed, defeated. He grabbed her hips and tentatively began returning her thrusts. He couldn't believe he was grinding against his sister. He couldn't take his eyes off of her face. He watched as she slowly took her tshirt off revealing a plain white bra. Her tits were so fantastic. He tried not to stare at them normally but he was transfixed as they strained against her bra. She brought his one of his hands to her breast and he began to knead.

"Oh god," she moaned, "you know just how to tickle me big brother." She reached behind and undid the clasp of her bra as he took off his shirt. Gently he pulled her down till she was lying down on top of him. He grabbed her pert ass and pulled her against him. He needed more contact so he quickly flipped her over and inserted his leg between hers.

He could feel her wetness on his thigh and instinctively he thrust his cock trapped tightly against her hip. He began gently building up speed until he was practically ramming her into the headboard.

"You like that Brenda? Do you like rough housing?"

"Uhhhhh. Oh God! Fuck yeah! Oh Greg! Don't stop! Don't Stop!!!" Her legs tightened around his thigh and he looked down as she squeezed her eyes shut and moaned her orgasm.

He was so close to cumming, but he didn't want their wrestling to be over already. He slowed to a stop watching the aftershocks of her orgasm pass through her body. Luckily he knew just how to ensure their little tryst continued. "See? I told you I could take you. I win." He rolled over on his back. Hoping that taunting still worked on his baby sister.

"What?" she screeched sitting up. He felt her weight shift and could tell she had gotten off the bed. His heart stopped, had he really upset her? Shit! He better not have fucked things up! He looked over to see his sister slide her pajamas and thong down her hips. His cock twitched. He could see how wet she was. Seeing his smug face and looking at the tent still in his pants, she said, "The score might be one –zero, but the game's only just begun." She had a devilish look in her eye that made him thank God his sister was so competitive.

"You won Round One, which was tickling," she informed him. "Aren't you hot Greg?" she asked playfully as she slid his pajamas down past his hips. She giggled when his cock popped free of his waist band. She threw his bottoms on the floor behind her.

"What's Round 2 then?"

She crawled up his body on all fours, her tight ass sticking up into the air. Her tits were resting gently against his cock. Her mouth formed an "oh" shape. Greg realized happily that his sister was about to suck him off. He was surprised however when he felt her lips on his pelvis just to the right of his cock.

"PPPPPFFFFFFFFFTTTTTTTTTTT!!" He jumped in surprise. "Round Two is Blowing Raspberries." She was smiling wickedly at him. Maybe challenging his Brenda wasn't such a good idea after all. She could be positively evil when she put her mind to it.

He leaned his head back resigned to her teasing. He just hoped that somehow he would get a blowjob out of this. He felt her hand lightly brush up and down his prick. She lifted it and he felt her tongue run along his balls. Holy fuck. He felt the hot warmth of her mouth envelop his balls and she began humming.

"HMMmmmmmmm. MMMmmmmm. Mmmmm"

Greg had never felt anything like that before. The only other girl to ever have sucked him off didn't go anywhere near his balls. He grabbed fistfuls of the quilt and moaned.

"Oh God Brenda! You're such a good sister! I fucking love you. You're making me so happy right now. So fucking happy." He looked up to see his sister raise her head and wink at him.

"You must really love raspberries," she giggled, "I just have one more spot to blow a raspberry." She wrapped one of her hands around the base of my cock. She looked like she was studying it. I moaned. Slowly she slid my dick into her mouth. She swirled her tongue around the bulbous head of my cock. She slowly began working more and more into her warm mouth.

"HHHHHmmmmmmmmmmmmm." She began to hum on my cock. The vibrations shot up my lower back. I moaned again in pleasure. I fought the urge to push her face harder onto my cock. My hips began to move of their own accord matching her thrusts .

"God I fucking love you so much. You're the best sister in the world. You're my little queen. You're so perfect. I don't deserve you baby. Hmmmm..." I gently rested one hand on the back of her head and she began sucking on my cock even harder. She was bobbing up and down on his dick like it was her fucking job. He pushed her hair out of the way so he could see where his dick was entering into his sister's mouth. "This is the best...." he hesitated, "raspberry I've ever gotten. Please don't stop I'm so close." That seemed to energize her even more.

She relaxed her throat and let his prick engulf her mouth completely. He could feel her nose poking into his pubic hair. Greg's eyes rolled back into his head. No one had ever deepthroated him before. His cock spasmed in his mouth and she pulled back til only the tip was in her mouth. Her hands stroked the rest of his shaft furiously. He groaned load and began pumping his jizz into her mouth. His sister didn't even pause sucking down his load until he was completely spent. She gently cleaned off the rest of his cock with her tongue.

"I think it's safe to say I won that round." Greg couldn't even form words.

"Mmm hmm." he agreed.

She curled up against his body and he reach down and hitched her leg up so he could feel her dripping pussy against his hip. He absentmindedly began to flick at her nipple. He was so fascinated by her lush body that he couldn't help but touch her.

His gentle strokes began to affect Brenda. Her hips started moving slowly against his hip, rocking back and forth. She reached down and gently rubbed his cock again. He felt the blood rushing to meet her touch and he sighed.

"You know," he began, "I won the first round, and you won the second round. That makes us tied."

"Well that's just unacceptable. I always win."

He turned her over on her back. Looking at her he slipped his finger into her mouth. "Round Three." he stated, not asking her for permission. Gently he eased his finger into her slit. Her hips thrust upwards bringing his digit deeper into her. She moaned. "Wet willy." he explained.

"More." she demanded. He added a second finger and slowly increased his thrusting. He leaned down and gently ran a finger around her clit. Her hips jerked and he had to hold her down with one hand to steady her.

He wrapped his lips around her bud and sucked as he continued to pound his fingers into her pussy.

"Oh my GOD!" she screamed. "Keep sucking. Suck me, suck me suck me!" He increased the suction and abandoned all gentleness. He had barely fit a third finger into her hole when he felt her clamp down tightly on him. Her hips undulated as her orgasm rolled through her. Her juices flooded his mouth and fingers but he didn't even pause until her thighs relaxed. He gently petted the outside of her lips, letting her come down slowly from her earth shattering orgasm. He licked up all her juices and gave her clit a chaste kiss before moving up to place a kiss on her mouth.

"You taste amazing." he told her when their lips parted.

"My kiss or my pussy?" she asked wryly.

"Both." he bent down and nipped at her neck.

"You're too sweet, Greg." His cock had gotten rock hard again while he ate his sister out. And he rolled on top of her as he gently kissed and sucked her neck. Her whimpers egged him on and he nipped at her earlobe. He hadn't even thought about fucking her for real until he felt the tip of his cock brush against her pussy lips. He worked her up into a frenzy kissing her whole body sensually until he could feel her body thrum with desire. He moved his hips until he could feel his cock brush against her pussy again. He moaned. He hoped she would be so full of lust that she would acquiesce. He wanted to thrust into her so badly.

He reached down and grabbed his cock. He rubbed the tip up and down her pussy and clit. "Please?" his whole being pleaded with her to let him.

"Alright." she agreed, "You can fuck your little sister if you really want to."

"Of course I want to," he told her, "You are the sexiest woman I've ever seen."

He could feel her juices running along the tip of his cock and he knew that she was ready for him to enter her. With trembling hands he guided his cock into her snatch until just his head was engulfed. He was scared to hurt her so he worked slowly pushing into her centimeter by centimeter.

"Fuck this." she snapped. She yanked his butt towards her until she engulfed his entire cock. "Fuck me hard. I don't want any pansy shit."

Her taunt was enough to send her into a frenzy. With a cry he pulled back and slammed back into her. He lifted her leg onto his shoulder so he could get better leverage and began pistoning in and out of her.

"You want to be fucked hard?" he asked. He slammed into her again, causing her to moan. She reached down and began to play with her clit. He controlled the pace of their fucking and continued to pump into her pussy.

Brenda rubbed her clit even faster. This was going to be a quick fuck and she needed to cum again with her brother inside of her. His pleasure was too primal for words. With a loud cry, Greg arched his back and thrust into her pussy burying his cock all the way in her. His fingers dug into her hips as he shot rope after rope of cum into his sister. He could feel her pussy walls squeezing his cock and her cries joined him as they came together.

Greg collapsed on top of her, still engulfed in her warmth.

"Too heavy." she told him, pushing him off of her. Their disconnection left them both feeling empty. They lay there for a while catching their breath. They were still cuddling when they realized their parents would be home any minute.

Greg bent down and kissed her gently. "Thank you," he said sincerely.

"For what" she asked as she flounced down the hall to her room. "We were just rough housing. There's nothing wrong with that."
