The Sister Trap

For the first time in weeks, Maddy slept soundly. A warm satisfaction wrapped around her like a blanket, as if everything in the world was going to be alright.

BANG. BANG. BANG.

Maddy shot straight up in her bed, eyes wide. The morning sunlight framed her pert breasts as her mind rushed back to consciousness. A shadow loomed beneath her door - someone was knocking.

Throwing on an oversized t-shirt, Maddy scrambled to answer, her mind racing with possibilities. Was it Elliot? Had he come to indulge his incestuous lust? Was he here to get a desperate glimpse of her in revealing clothing? But Maddy's face fell when she opened the door to see none other than her mother, Eleanor.

Eleanor was the picture of fitness. Wearing tight sweatpants and a crop top, the mom was fully prepared for her morning run. The top she wore couldn't help but draw attention to her bust, which was larger than Maddy's by far. Eleanor worked hard to keep her body toned and tight, such that a passerby might mistake her for Maddy if they weren't looking too closely. Today, Eleanor wore a stern look of disapproval, her arms crossed beneath her bosom, squeezing her breasts forward so much that Maddy thought they might escape from her top.

"I got a call from your coach last night." Eleanor's brow furrowed, looking Maddy up and down. "She said yesterday didn't go so well." Her voice was hard. She put a lot of stock in the successes of her daughter.

"I just wasn't focused." Maddy replied.

"Don't let it happen again," Eleanor snapped. "You have a responsibility as a leader." Maddy's heart sank. Never before had her libido gotten in the way of her responsibilities. But now... Something about Elliot pervaded her every waking thought. Even now, with her mom standing in front of her, Maddy couldn't help but picture Elliot's hard, cum-covered cock...

"Madeline Owens! Are you listening to me?" Maddy's eyes snapped back to meet Eleanor's. She'd been staring off into space.

"Yes, mom. I'll do better, I promise." Maddy said, downtrodden.

"Actions speak louder than words, honey." Eleanor glanced at her watch. "It's time for me to go. Your father is at the golf club today. Try to use today productively, m'kay?" Maddy nodded sullenly. "Oh, and hon," Eleanor continued. "See if you can get your brother to do something worthwhile today?"

And with that, Maddy was left alone in a house with Elliot once again.

*****

After a shower, Maddy changed into her schoolgirl uniform. She chose a pair of white cotton panties and forwent leggings entirely. Maddy also omitted a bra, instead wearing her white dress shirt with the top two buttons strategically undone. She admired herself in the mirror, tracing a finger down her chest and towards the modest cleavage that showed.

Downstairs, noises sounded from the TV. Elliot was awake.

Maddy smiled at her reflection, appreciating the curves she had. A renewed confidence had energized her since last night. She knew that her body could drive Elliot crazy, if only she could press the right buttons.

Practically skipping downstairs, Maddy stopped short at the sight of Elliot lounging on the couch. He wore the laziest of Sunday outfits, a faded graphic tee and gray sweatpants. Maddy couldn't help but bite her lip as she caught the very visible outline of his cock against his sweatpants. It was like

he

was trying to tease

her

.

"Mom said you have to get off your lazy ass today." Maddy smirked.

"Fuck off, Maddy." Elliot rolled his eyes and turned up the volume on the TV.

"Uh, fuck you! Don't you have homework to do?" Maddy grimaced. Elliot could be an annoying little shit for how hot he was. Elliot just responded by further turning up the volume.

"Elliot." Maddy moved to block Elliot's line of sight to the TV. She crossed her arms beneath her breasts, squishing them together.

"Come on," Elliot's voice was edged with annoyance. "Stop being such a bitch." He turned up the TV even higher, blaring it behind Maddy.

"Give me that!" Maddy lunged towards Elliot, throwing herself across him in an attempt to snatch the remote from his grasp. Rage coursed through her body, igniting her senses. Every part of her wanted to jump Elliot's bones right then and there. All the anger and frustration and unreasonable expectations placed on her - it would feel so good to take all that out on his hard cock.

Maddy became very aware of her boobs pressed up against Elliot's chest as her finger tips stretched out. She was practically straddling her brother as she fought to grab his arm. But Elliot held the remote behind him, his long arms keeping the item just out of reach.

It felt heavenly to be so close to Elliot. Maddy could feel the warmth radiating between them as her chest pressed against Elliot. She strained further, causing her shirt to tighten around her figure. With the top of her shirt unbuttoned, Elliot had an unobstructed view of her perfect tits.

"Give it up, sis!" Elliot yelled as Maddy pressed even closer against him.

"Ughhh!" Maddy released the tension in her body, and sat back on Elliot's lap. There, pressed against her naked thigh, was a rapidly growing hardness in Elliot's sweats.

"Now gerroff me!" Elliot tried to shove Maddy off of him, but Maddy was ready. She hooked her arms around his shoulders and used her momentum to pull Elliot back with her. Together, they tumbled onto the floor with Maddy on her back.

Not wanting to give Elliot the upperhand, Maddy locked her legs around Elliot's waist and used all of her core strength to push Elliot over. Caught by surprise, Elliot was forced onto his back with Maddy sitting triumphantly on top of him.

Maddy's skirt covered the area where Elliot's crotch met Maddy's groin. But she could feel her brother's dick, already so stiff beneath her skirt. The only thing that separated his penis from her soft skin was Elliot's thin gray sweatpants.

"Fucking hell, Maddy." Elliot groaned.

Make that noise again baby brother.

Maddy felt her panties moisten. "Get the hell off of me!"

"Oh, come on bro." Maddy bit her lip playfully. Above Elliot's head she swung the remote control back and forth. Somehow the device had swapped ownership during the scuffle. "Are you just gonna admit defeat?" Maddy felt like there was a furnace of desire between her legs. She was keenly aware of Elliot's now rock-hard cock trapped beneath her thigh. It would just take a little movement to...

Elliot half-heartedly tried to snatch the remote. Maddy yanked it out of reach, taking advantage of the movement to adjust her seat on Elliot, landing her crotch directly on Elliot's throbbing cockhead. Maddy had to fight not to roll her eyes back in her head and moan. It took every fiber of her being not to grind her pussy lips against the length of his shaft while she devoured his lips.

Instead, Maddy leaned forward, using the adjustment to press her clit against the head of Elliot's cock. Maddy's eyes fluttered in pleasure, but she remained in her disciplined composure. She placed a pointed finger on Elliot's chest. He was breathing ragged gasps beneath her, ostensibly from the sudden physical exertion of wrestling, but Maddy knew the real reason why. His normally clear green eyes were cloudy with lust. And Maddy could swear that his pelvis was minutely thrusting against Maddy's crotch.

"You might be so much bigger now..." Maddy whispered, letting her voice linger on the word 'bigger.' "But I can still beat your ass in a fight." Maddy's fingers curled into a fist around Elliot's t-shirt. God, she could feel his cockhead twitching with desire as she spoke. Her pussy was on fucking fire. Her nipples were hard and very visible through the fabric of The translucent dress shirt. In that moment, Maddy wanted nothing more than to abandon all pretenses and ride her brother into oblivion.

But Maddy was made of sterner stuff than that. With a wicked grin, Maddy bounced up off Elliot. She made sure to stand where Elliot could get just the barest glimpse of her panties. All seven inches of Elliot's shaft were clearly visible, stretching his sweatpants into a pitched tent. But Maddy kept her eyes fixed on Elliot's upper half, pretending that she didn't notice.

"Mine now. You can have it back when you actually get some shit done." Maddy wiggled the remote once again in victory. With that, Maddy skipped away up the stairs. She could feel Elliot's stare boring into her as she left.

Look at my sweet juicy ass bro.

Victory.

Upstairs, Maddy slammed her bedroom door behind her and immediately jammed her fingers into her sopping wet cunt. She arched her back against the wood paneling - her mouth forming a silent moan. Maddy had never been so close to her brother before. Never before had she been so intimately aware of his arousal. The memory of his hardness twitching between her legs made her squirm with pleasure.

She sank to the floor, knees spread. Maddy's fingers worked double time on her clit. Her other hand went up to pinch her hard nipples, yanking and teasing them. She bucked her hips, humping her own hand with a feverish intensity. The close contact with her brother's manhood had only put more fuel on the flame of her desire, and now it was as if nothing could quench that fire.

Frustrated, Maddy went to her closet for help. Every inch of her body buzzed with arousal. The length of cock that she had oh-so-briefly rubbed against her clit downstairs was transfixed in her mind. Maddy wanted it inside her. She wanted to take the full length of her brother's cock and ride it up and down until it filled her up completely. Maddy wanted to squeeze herself around Elliot's cock and tighten around him until he lost control and cummed wildly inside her. Fuck, that was too fucking hot.

Tucked away in the shoebox at the bottom of her closet was Maddy's collection of secret sex toys. Immediately, her fingers wrapped around the silicone dildo that had become a favorite of hers recently. Deciding she might need something extra today, Maddy also grabbed her pink vibrator. Acting as if she would die without filling her pussy right away, Maddy planted the dildo on the ground and sunk it deep into her cunt.

The filling feeling of pleasure immediately made Maddy let out a soft moan. She didn't care. Elliot wouldn't be able to hear her from downstairs. She bucked her hips up and down, gently riding the dildo. The vibrator went to her clit, turned to the highest setting.

"Fuckkk..." Maddy groaned softly. "I want your cock, bro..." Maddy's eyes rolled back in her head as she bounced up and down. The intensity of her fuck session sending pulsing waves of erotic pleasure through her body.

WHAM.

Elliot's bedroom door slammed shut, followed by movement on the other side of Maddy's bedroom wall. Maddy went still with the dildo still inside her. Fuck me.

Anxiety raced through Maddy's mind, drowning out the feelings of arousal. Had her little spectacle downstairs been too obvious? While she tried to calm herself by telling her that no reasonable guy would actually guess that their sister was trying to seduce him, the feeling that maybe she had gone too far persisted. Was he angry with her?

Curiosity got the best of Maddy. She felt along the wall she shared with Elliot until her fingers curled around a piece of beige painter's tape. A painstaking amount of time passed as she worked it off the wall in an effort to avoid making an obvious ripping sound. Behind it, at about waist height, was an eye-sized peep hole.

It had been there ever since the siblings were kids. They'd widened it a fair amount when they'd discovered it and often used it to send secret messages to each other and conspire when they'd been sentenced to timeouts in their rooms. But when they became teenagers they sealed the hole with tape and forgot about it. Maddy was pleased to see that Elliot's side of the tape had already peeled away.

Peering through the peephole, Maddy had to stifle a gasp when she saw Elliot leaning back in his chair, pants to his ankles, and his seven-inch cock fully hard. He was busy bringing something up on his computer - porn, Maddy guessed. Keeping herself glued to the eyehole, Maddy brought her fingers back to her aching cunt, imagining it was the throbbing cock only a couple feet away that was penetrating her.

From this angle, Maddy couldn't make out Elliot's face, so she had to settle for imagining what type of desperate lust he was feeling right now. Sister-induced lust. The porn on the computer started playing as Elliot brought out his phone. Is he taking pictures of his cock? But then Elliot set the phone on the desk in front of him, just visible for Maddy to see the contents. There, staring back at Elliot beneath the computer screen playing porn, was the naked selfie Maddy had sent her brother.

The sight sent a string of erotic impulses through Maddy's already hot and bothered body. She grabbed her silicone cock and shoved it up her wet cunt, fucking herself from behind as she bent forward. Her eyes were fixated on Elliot's twitching member. At the edge of her field of view, the porn video playing caught her eye: "Slutty big Step Sis gets "help" from little Step Bro." Elliot was stroking cock with both hands, slathering it with precum as the blonde in the video began to moan.

Maddy couldn't believe Elliot was jacking off to her nude selfie. He's imagining that I'm in the porno. The thought made Maddy's senses go haywire. She jammed the cock into her pussy as deep as it would go, before pulling it all the way out and ramming it back in. The pleasure was so intense that she immediately orgasmed. The buildup of sexual tension that had tormented her pussy all day finally released, sending electrifying pulses of pleasure across her body. Maddy clapped a hand to her mouth as her eyes rolled back in her head. She was shaking. Her muscles uncontrollably spasming around the cock that she'd shoved inside her. Fuck me, little brother.

When the pleasure subsided enough for Maddy to be in control of her own body again, she immediately returned to her peephole. There, Elliot had picked up the pace of his jacking off. Maddy couldn't help herself, she planted her dildo back on the ground in front of the whole and began to fuck herself yet again. On the other side of the wall, Elliot was thrusting his hips in time with the porno, his cock straining with desire, his hands forming a tight hole for his cock to fuck.

Maddy brought her vibrator to her clit. This was the hottest thing I've ever seen. She timed her movement on the dildo with Elliot's pumping of his own cock. In his mind, he was fucking his sister. In Maddy's mind, he was fucking her too. Maddy couldn't believe how slutty she felt at that moment.

"Ohhhh, baby bro, please fuck me." The blonde in the porno moaned loudly, and Maddy swore that Elliot moaned under his breath in response. Elliot's movements were growing more erratic, and so Maddy fucked herself faster to match. She was desperate to get her dildo deeper, to satisfy a deeper craving. Maddy's cunt was still sensitive from her last orgasm. The intensity with which she was fucking herself hurt, in a sweet way. But she didn't care. She would destroy herself in order to enjoy the sight before her.

"You're such a fucking slut, Maddy." Elliot whispered. The girl in the video was getting fucked from behind now by her step-brother. He was pulling his sister's hair. Maddy longed for Elliot's cock to fill her up. It could touch places inside her that none of her toys could reach.

"Fuck me harder, bro," Maddy mouthed in response.

Elliot grabbed the phone, bringing the naked photo of Maddy in front of his cock as he pumped his dick with increasing enthusiasm. Strands of milky-white precum slathered his cock. His thrusting became more and more animalistic. In the background, stepsiblings fucked each other in earnest, filling Elliot's room with sexy moans. Maddy's own orgasmic juices had leaked all over her dildo, transforming it into a slick mess of her own arousal.

"Oh my fuckin' goooood..." Elliot let out a sustained moan. "Take it all, sis." His cock erupted as thick white ropes of cum shot from the tip and covered the phone screen of Maddy's naked body. "Take my fuuuucking cum."

On the other side of the wall, Maddy shoved her dildo into herself as far as it would go, holding it there as her pussy pulsed, once, twice, and then finally she felt her core clench and unclench around the silicone cock as her second orgasm flooded through her. The sight of Elliot's phone, depicting Maddy's nude selfie, covered in Elliot's cum sent Maddy over the edge. Maddy kept her eyes fixed on Elliot's cock and the sight of his phone screen. She imagined that he had just sprayed his load all over her body, his load covering her petite tits.

Maddy's second orgasm hurt so good. The waves of delicious orgasm caused Maddy to tremble and quiver. The muscles in her cunt squeezed around the cock inside her over and over, harder and harder than before. She was left with an empty feeling of satisfaction as she descended from the pleasure. How can I ever cum that good ever again?

Back in Elliot's room, Elliot was staring at the cum-covered photo of Maddy, his cock rapidly softening.

"Oh my god." Elliot grabbed a pair of dirty boxers and cleaned off his phone screen, wiping away the sticky cum. "What the hell is wrong with me?"

Elliot swiftly pulled up his pants and threw on a jacket. He seemed frantic, as if he were not sure what to do with himself. Maddy could just make out that he was muttering and shaking his head as he scrambled around the room to get ready to go out. In another minute, he'd called a friend and made plans to meet up at the mall.

Maddy noted that he did not delete her selfie.

She sat in her own juices for a while. Maddy let the dildo fill her up while she ran the memory of what just transpired over and over in her head. The sight of Elliot cumming so hard for the sight of her naked body had been ludicrously hot. That was everything she wanted - almost. Elliot still didn't suspect Maddy was up to anything nefarious. And he was unable to resist his desire for her body.

Maddy smiled as she idly played with her still erect nipples. Her brother was close to breaking. She could feel it. It wouldn't be long before he would be unable to resist his carnal desires. It wouldn't be long before he would give in and take her.

For now, however, it was a school night and Maddy was dramatically behind on studying. Perhaps the two recent orgasms and the absence of Elliot would allow her a few hours of solid focus on studying. After that, Maddy was going to have to get creative about how to ramp up her teasing of Elliot throughout the school week.
