[mf] [incest] [brother/sister] Chelsy is blackmailed into being her brother’s slut

***I wrote this a while back for a girl I met online. She had some fun fantasies she wanted to explore as you’ll soon notice. I haven’t really proofread or edited it much. Just found it and wanted to post it. Hope you enjoy.***

As Chelsy strolled down the hallway, she heard a noise coming from her step brother’s bedroom. Noticing his door was open slightly, she decided to investigate.

Her tiny 5’4 frame quietly crept towards the doorway. As she approached her dark eyes peered between the crack in the door and what she saw made her knees go weak.

She stared at a long thick veiny cock, well cut, growing more and more red as it was gripped by a large strong hand.

Chelsy couldn’t look away as she watched her older step brother laying on his bed and  stroking his cock. Her heartrate rose and she did her best not to breath too loudly. Her fingers swirled around her dark hair which hung a few inches below her shoulders.

Chelsy’s eyes explored her step brother’s body. His muscular arms, firm and and chiselled bearded face. She had always thought he was hot but since he was her step brother, had never pursued the thought any further. Now she wanted to barge in and ride his stiff thick cock.

But she new she couldn’t  if he knew she was watching he would likely be very upset with her, at least she thought so.

Suddenly Chelsy realized her hand had slid into your pants. Her fingers pressed her clit through her soft panties and she let out an involuntary moan.

Immediately Chelsy covered her mouth, hoping her step brother didn’t hear. But he carried on jerking his cock, not seeming to notice.

Chelsy became very wet and her entire body was heating up. Her nipples had hardened and we’re poking through her breezy t-shirt. Her fingers massaged her clit furiously as she gazed upon that huge cock infront of her.

Soon, Chelsy slid two fingers inside her soaking pussy. She let out another moan, louder this time. She barely cared if anyone heard anymore, she just needed to get off. With each stroke of her step brother’s hand she thrusted her own fingers deep inside of her, imaging they were his cock.

Faster and faster her step brother went, groaning louder and louder, and so faster and faster Chelsy went, moaning louder and louder. Until she saw her step brother’s balls tighten and his cock twitched in his hand, and his thick white cum erupted out and dripped down his shaft, glistening it and his hands. Chelsy thrusted her fingers deep and hard one last time, and came all over them while she watched her step brother’s seed leak from his pretty cock.

Her fingers and panties were soaked as she breathed heavily. Her knees were so weak she could barely move, but as she caught her breath Chelsy heard her step brother recover from his orgasm and begin to stir. She moved back to her room as quickly and quietly as she could.

As she entered her room she had already decided she needed to fuck her tight young cunt some more thinking about what she just saw. Chelsy was so excited for this, she forgot to close her bedroom door all the way, and as she lay naked and uncovered on her bed, knuckles deep in her needy pussy, she didn’t notice a figure outside her door, watching her as she had just watched him.

 

Chelsy spread her legs as wide as she could, trying to get her fingers as deep as she could. Trying to match her brother’s length.

She reached under her bed and brought out her silver vibrator. Usually she didn’t use it when people were home because she was concerned about someone hearing the buzz, but tonight she did not care.  She turned it on and shoved it deep into her soaked pussy, moaning louder than she intended as she did. Her other hand found her hard nipples, desperately pinching and twisting them for more pleasure.

Chelsy closed her eyes and imagined her brother fucking her tight pussy. His strong lean muscles on top of her while he thrust deep into her. Her extra hand slowly gripped her throat. As she squeezed harder and harder she imagined his hands doing just that to her.

As her other hand thrust her vibe into her pussy and massaged it against her clit, Chelsy got closer and closer to an orgasm.

Her breathing quickened and she began sucking on her fingers as they left he throat. Over and over her vibe pleasured her pussy, imagining it was big brother’s cock.

Suddenly Chelsy bucked uncontrollably against her vibrator as she came. She moaned loudly, louder than normal while people were home. Her entire body shook while she came all over her vibe and fingers and she sucked and moaned on her fingers hard. After what seemed like minutes the orgasm subsided and Chelsy relaxed. She brought her vibe to her mouth and slowly cleaned her juices off with her tongue, catching her breath as she did.

Before she new it she passed out, exhausted from one of the best orgasms of her life, imagining her brother fucking her.

Chelsy was awoken suddenly, her mouth covered and her body restrained. She was so confused and tried to scream but it was muffled by the hand. Once she got her bearings and focused on the figure towering above her, she realized it was her big brother. Then she realized she was still naked. Her wrists were tied above her head to her headboard. As she stared at her brother she saw he was also naked. His firm body leaning over her. His hard cock waving close to her face.

“Shut up” he whispered and slowly Chelsy calmed down. Then she looked in his hand. He was holding his phone and there was a video playing. It didn’t take long to realize the video was of her, fucking herself earlier. Her eyes widened and her face went red in embarrassment.

“You’re my slut now little sister. You must do everything I want, or else I’ll show everyone in school. Nod if you understand.”

Chelsy nodded. Then her brother took his hand off her mouth and smiled. He climbed onto her naked chest so his hard cock was above her face. Slowly he brought it to her mouth and smiled as he Chelsy opened wide.

“good little sister,” he half groaned as he felt her warm tongue massage his hard shaft. Slowly he pushed his cock deeper and deeper and Chelsy realized she was completely at her brother’s mercy because her hands were tied above her head. He began to thrust over and over, deeper and deeper. He used her throat for his cock’s pleasure and she listened to him groan while she did her best not to gag.

Soon he pulled out and began jerking his cock in his big strong hands. It glistened with her saliva. While he jerked he shoved his balls into Chelsy’s mouth. She instinctively sucked on them and heard him groan some more. He rubbed his balls a over he face, spreading her saliva all around, covering it.

“Good little sister,” he said as he pulled away and straddled Chelsy’s stomach. He slapped his hard dick against her tits. Slowly he rubbed the head of his cock around each nipple, dripping more saliva from his mouth when needed.

Chelsy let out an involuntary moan as she watched her brother play with her breasts. Each touch sent a sensation to her pussy. She knew she must be very wet at this point. She listened to her brother groan as his hard cock massaged her tits. Then he leaned down and began sucking on them with his mouth.

Both his hands gripped her breasts from the bottom while his lips went back and forth between the two. Chelsy began moaning louder.

“Shut up sis,” he said as he grabbed a pair of dirty underwear and shoved them in her mouth. “You don’t want anyone to hear you.” He slapped her cheek before attending to her breasts again.

Her brother became more aggressive with his mouth and started biting her nipples. The pain sent a shockwave throughout her body and Chelsy struggled against her restraints. But there was no use. He could inflict all the pain to her nipples he wanted.

And he did, going from one to the other he would bite hard and pull, enjoying her reaction to the pain. She quietly screamed into her panties that we now soaked in her own saliva. As he bite one nipple his fingers pinched the other. Over and over, Chelsy endured the torture, until finally he stopped. Gently he licked both nipples, massaging them with his tongue. They were so swollen and sensitive, his tongue’s touch felt 10 times better than normal. She moaned loudly into her panties suddenly needing her pussy to be pleasured to an orgasm.

Big brother then turned around, so he was still straddling Chelsy’s stomach but he was facing her pussy. Soon she felt his fingers touch her clit. Chelsy moaned looking down her body but all she could see was her brother’s back and his firm ass sitting on her.

His fingers began circling her clit and he had obviously added some saliva. She moaned some more, realizing her big brother had experience at playing with a pussy.

Then a finger easily slid inside her soaking wet pussy. She moaned loudly into her panties and big brother whispered “what a slut you are little sis. You gag on your brother’s cock and get your tits tortured and yet your pussy is dripping wet. You will be a fun little fuck toy for me to play with.”

Chelsy didn’t care in this moment, all she wanted was her big brother to get her off. He inserted a second finger, stretching her young pussy slightly. He began fucking her pussy with his two fingers, thrusting them deep in and out, while his other hand massaged her clip. Chelsy moaned perhaps too loudly.  Her hips tried to buck but her brother’s weight held her down.

Then he slowly added a third finger, stretching her tight wet hole. It sent pain and pleasure throughout Chelsy’s body. He finger fucked her with three fingers, slowly building up a faster and faster pace. Soon he was slamming his three fingers as deep as they would go inside Chelsy’s dripping cunt. Her orgasm was quickly building and she moaned loudly, almost screaming through her soggy panties.

Suddenly big brother stopped and pulled his fingers away. Chelsy’s hips tried to buck, being so close to orgasm, but she couldn’t achieve it. She bit on her panties in frustration as her big brother turned on her stomach to face her once again. He showed her his three fingers that were inside her. They were glistening with her juices. Slowly he pulled her panties from her mouth and inserted his three fingers. Her tongue instinctively began cleaning them off.

Chelsy stared up at her big brother with pleading eyes. He spoke. “You really want that orgasm don’t you? You sick fuck. You want your big brother to finger bang your tight young pussy and give you a screaming orgasm. You need it don’t you?” he paused waiting for a response. “Yes,” Chelsy spoke, muffled bh the three fingers in her mouth.

Her brother began finger fucking her mouth now, and Chelsy had to concentrate on her breathing to not gag. “You’re a good sister slut. The only way I will finger fuck you to orgasm, is if I then get to fuck your asshole.”

Chelsy’s eyes widened. She had done anal before but had never enjoyed it.

“No promise of anal? Then I’ll just go back to edging you,” he said while still finger her throat. He was trying to get deeper and deeper. She was taking his fingers well, until his longest one hit the back of her throat. Chelsy instantly gagged and spat up some fluid that ran down her cheeks onto her pillow.

Her brother pulled his hands out of her mouth, awaiting a response. As Chelsy caught her breath she said “okay.”

“Okay what?” was big brother’s response.

“Okay, let me cum and you can do anal on me,” she said still breathing heavily.

“No no. I don’t think you understand. Beg me to fuck your asshole, so that I will give you an orgasm.”

Chelsy laid there, saliva all over her face. The taste of her own juices in her mouth. Her tits hard and soar from being abused. The sheets beneath her ass soaked from her dripping pussy. She looked up at her big muscular brother smiling down at her. “Please big brother. Please fuck my asshole as hard as you can. I’m begging you because I’m your little slut and I need you to finger bang me to orgasm. So please stretch my asshole with your big cock big brother.”

That seemed to satisfy him. This time he laid on his stomach facing her pussy. She looked down at he head as he began licking her swollen clit. With no more panties in her mouth Chelsy moaned loudly before turning her face into her pillow and arm, trying to muffled the noise. He began massaging her clit with his warm wet tongue and soon thrusted three fingers deep into her wet pussy once again.

Chelsy was in heaven. Her body felt amazing. Over and over her brother’s tongue flicked and circled her clit and over and over his three fingers drove deep into her wet pussy, slowly getting harder and faster as he built up momentum.

Finally Chelsy was going to cum. “Make sure you ask for permission little sister,” brother told her.

As she got close, she could barely hold in a scream. His fingers and tongue felt so good. “please may I cum big brother?” Chelsy asked.

“Not yet,” he said as he continued his assault on her pussy.

A few more seconds past and Chelsy felt like there was no way she could hold it in anymore. “please may I cum big brother?”

“No”.

She moaned loudly into her arm, pushing off her orgasm. Her entire body was on fire. Pleasure was pulsating through it and she could feel her orgasm ready to erupt.

“Please big brother. Please I need to cum. I am a little whore that just needs to cum all the time.”

“You may cum,”

As the last word left his mouth her orgasm hit. Chelsy screamed much louder than she should, bucking her hips against her brother’s fingers and face, trying to get as much pleasure as possible. The wave of extreme pleasure washed over her over and over as she came as hard as she could remember. Her juices soaked her bed as the dripped down her pussy.

Soon it passed and Chelsy laid there, exhausted and breathing heavily. But before she knew it, her big brother flipped her onto her front.

He sat behind her stroking his hard cock with one hand, and pulling her ass cheek to reveal Chelsy’s tight young asshole. Then she felt his warm wet tongue between her cheeks and slowly find her asshole. She moaned into her pillow as his tongue fucked her little asshole.

Then it stopped. “this is my ass,” he said as he slid her hard cock between her ass cheeks. “I will use it whenever and however I want,” he whispered in her ear.

Then he pulled her cheeks apart and pushed the head of his cock into Chelsy’s asshole.

The initial stretch was painful and Chelsy screamed into her pillow. Her big brother’s cock continued to venture further and further into her ass. Chelsy felt every millimeter as she listened to him groan in pleasure. Her ass gripped his long hard cock. Deeper and deeper it went until it stopped. Chelsy looked back. He was balled deep in her ass.

Her landed a few hard spanks on her ass as he enjoyed his full length. Chelsy wanted him to hurry up and get it over with but it seemed as though that wasn’t big brother’s intention.

He laid down on top of her, slowly sliding his cock a few inches in and out, but always saying deep in her rectum. His hands reach under Chelsy’s body and gripped her tits. His nose sniffed her hair as he slowly licked her neck up to her ear, before chewing on it a little.

“I am going to enjoy using your body over and over. And what I will enjoy most about it, is you hating it.” He whispered.

Then he sat up, gripped Chelsy’s hair and began fucking her asshole hard. Her back arched and she screamed with each thrust. Over and over. Every thrust was a pull on her hair. Her ass cheeks began to redden from brother’s hard spanks.

As he continued to fuck her his hands moved to her throat and mouth. One gripped her throat hard, restricting her airwaves. The other pushed two fingers in deep and pulling on her lips, fishhooking her.

Harder and harder he fucked her asshole and more and more he abused her. Just as Chelsy thought she was going to pass out, big brother released his hand from her throat. He then grabbed her lips from the other side and pulled.

She started to moan, as her ass had finally stretched out to accommodate her brother’s hard cock. Her pussy was rubbing against the sheets below. Her body naturally began to buck back against his long hard cock, forcing it deeper into her ass.

Soon she was soaked again and on the edge of an anal orgasm. “May I cum please big brother?”

“Yes” he told her and she moaned as he pushed her face into her pillow. He could feel her muscles contracting from the orgasm. He fucked her harder, pounding her tiny body into the bed.

Soon he was close. He spanked her ass hard and pulled her hair once more. Her moans and screams put him over the edge and Chelsy felt his cock pulsate inside her tight ass, then she felt shot after shot of his warm cum fill up her asshole.

Big brother let out a final groan before collapsing on the bed beside her. He reached up and untied her restraints. “Clean my cock up.”

Slightly hesitant as his cock had been in her asshole, Chelsy decided to obey out of fear of what the alternative may be. She moved her head to his cock and licked the entire shaft with her tongue before taking it into her mouth. He was still ¾ hard as she slurped his cock clean. As she did, she imagined what it would feel like in her pussy and before she knew it she was rubbing her clit was she sucked her brother’s dirty cock clean.
