The Sister Trap Ch. 04

Monday

By the time Maddy woke up, she had already devised the perfect plan for teasing Elliot throughout the week. Her panties were drenched from another wet dream. This time she had dreamt of the hole in their shared bedroom wall being used for… other purposes. In her lust-induced imagination, she had sucked on Elliot’s cock through the wall until he shot thick ropes of cum down her throat. Coincidentally, the dream had given her one final idea to top off the week of teasing.

From the other side of the wall, Elliot’s alarm clock beeped in rapid distress. This was followed by a muffled groan as Elliot shambled out of bed. That was the signal to put her plan into action.

Maddy scrambled to gather up her school garments in a bundle and left her room, making for the siblings’ shared bathroom. She wore nothing but a lacy pink bra and panties that had gone semi-translucent from wetness, only the bundle of clothes she held provided any modesty. When she approached the bathroom, Elliot’s door swung open, revealing her brother standing there in nothing but his boxer shorts.

Maddy stopped short, her eyes immediately drawn to the outline of his semi-erect cock in his boxers. She almost started salivating at the thought of one thin layer of fabric separating her from seeing his cock in all its throbbing glory. Elliot seemed stunned, his eyes roaming over her body.

“Uh, hey, sis… I thought you’d be up and showered by now.” Elliot’s eyes were glued to her boobs. Maddy smirked, and stuck out her barely concealed chest a little further.

“Ugh, sorry Elliot! I slept in and I really need to shower. I’ll be quick, okay?” Elliot nodded, awkwardly. Of course, Maddy had intentionally started her morning routine later this morning, so as to “accidentally” run into Elliot in the hall.

“Thanks, bro. You’re the best!” Maddy grinned, and then in a well-practiced move, let the school uniform she was carrying fall to the floor.

Her body was left almost completely unobscured for Elliot’s lustful gaze. Maddy’s nipples were hard enough that she swore they could be seen protruding from beneath her bra. If Elliot looked hard enough, Maddy was sure he could see right through her panties too. But Maddy didn’t give Elliot long to stare as she hastily picked up her clothes, bending down such that he had an ample view of her cleavage.

“I’ll be out quickly!” Maddy smirked, noticing that Elliot’s morning wood had actually seemed to grow.

With the shower running, Maddy stripped out of her clothes, and almost immediately started jilling herself off. She brought the showerhead to her pussy, moaning softly at the intense pleasure the water pressure offered. Her mind was clouded with thoughts of Elliot’s cock growing at the sight of Maddy in her underwear. She started to lose track of time as she ran her hands up and down her body in sensual bliss…

“Hey! Are you almost done in there?” Elliot knocked at the door. Shit, how long have I been masturbating? Hastily finishing up her shower, Maddy gets dressed without finishing her jilling off session. She’s frustrated, but gets ready knowing that her pleasure now is just distracting from her ultimate goal. Besides, it might be nice to save my orgasm for a special surprise at the end of the week…

Just before she leaves the bathroom, Maddy casually discards her dirty panties in the corner. To anyone else, it would look like she just missed them in the morning rush.

“Okay, I’m ready!” Maddy brushed past Elliot, conscious of her breasts pressing against his shoulder as they traded places. She rushed away before Elliot could see or comment on her left-behind panties.

Later that night, Maddy went to the bathroom. She smiled. Her panties had gone missing.

Tuesday

On Tuesdays, Maddy and Elliot shared third and fourth period together. Maddy took this as ample time to tease Elliot in less direct ways.

Wishing to keep up pretenses, Maddy treated Elliot like she always treated her brother. That is, she pretended as if she didn’t exist. Instead of even acknowledging him as they sat next to each other in third period, Maddy kept her attention solely on her best friend of several years, Christina. The two blondes spent the period whispering and exchanging notes while the teacher was looking away.

But, at the same time, Maddy let her leg drift towards Elliot, brushing against his thigh or knee every so often. She never so much as looked at him. But she made sure that she made some sort of accidental contact with him every ten minutes or so.

In fourth period, Maddy sat in front of Elliot. This time, she took the liberty to yawn and stretch as often as she could get away with it. Maddy would stretch her arms high into the air, causing her dress shirt to rise and reveal her lower back. Towards the end of class, Maddy scooted backwards in her chair, causing her skirt to slip down, revealing just a glimpse of the panties that covered her tight ass.

At the end of class, Maddy was pleased to note that Elliot stayed in his chair long after the bell rang. Perhaps he was waiting for something of his to calm down?

Wednesday

Wednesday passes in a blur of classes and cheerleading practice. But, that evening, Elliot goes to hang out with his friends, leaving his room unguarded.

Maddy stepped into his room, the odor of teenage boy thick in the air. She wrinkled her nose. She was here for one thing and one thing only.

There, she spied a flash of pink hidden in a pile of clothes near Elliot’s desk. Maddy pulled at the corner of the fabric to reveal her cotton pink panties that had gone missing from the bathroom on Monday.

Maddy gasped. There, in the crotch of the panties, was the stain of recently dried cum. She brought the panties to her nose and sniffed it. The acidic smell of his semen driving Maddy’s senses wild. How many loads did he blow into these?

Without thinking, Maddy slipped a hand into her underwear as she examined the panties. They were almost unrecognizable in the deluge of cum that slathered the crotch. Maddy rubbed her clit, thinking about the pink panties wrapped around Elliot’s hard cock. How many times had he jacked himself off with these, thinking about his big sister?

Suddenly, Maddy was yanked out of her trance by the sound of Mr. or Mrs. Owens moving around downstairs. She hastily threw the panties back in the pile she’d found it, and removed her hand from her own pussy. As much as her pussy ached for release, Maddy knew it would be all the sweeter if she could just wait…

Thursday

On Thursday evening, Mr. and Mrs. Owens went out on a date together, leaving Maddy and Elliot in the house alone.

While Elliot was busy in his room, Maddy turned on the TV and laid down on the couch, arranging herself as if she’d fallen asleep watching. But first, Maddy delicately pushed her skirt up her legs, revealing more of her milky white thighs and just a hint of her pussy mound. Then, Maddy closed her eyes, and turned up the volume to a level that was bound to annoy Elliot.

Several minutes later, Elliot came stomping down the stairs.

“God, can you turn that-” Elliot cut himself off at the sight of Maddy’s vulnerable position. Maddy tried to make her breathing as slow and natural as possible, although she could not stop the arousal that drenched her pussy.

Maddy’s breath caught as she felt Elliot move closer to her. He was standing over her now, his eyes roaming over her “sleeping” body. Maddy wondered what he was most taken in by. Was it her shapely legs? Was it her camel toe? Was it her cleavage? Was it her full, red lips? Maddy had half a mind to open her eyes when Elliot walked away without a word.

That night, Maddy could hear muffled moans echoing from the otherside of the wall as Elliot dealt with his lust.

Friday

By Friday, Maddy was a horny mess. It had been years since she had gone more than a day or two without getting herself off, and Maddy had refrained from orgasming all week. Her pussy ached with desire. She found herself needing to change her panties two or three times a day from the arousal that constantly leaked. Friday’s classes were the worst, with Maddy’s focus constantly elsewhere as she imagined her brother pounding her holes from every angle. It was time to put the last step of her plan into action.

[adv]

That evening, Maddy’s eyes lit up when she saw Elliot’s door closed with the light on. I want to see you try to resist this, baby brother.

In her room, Maddy sat on her knees, still fully dressed in her school girl outfit. Every instinct in her wanted to shove a hand up her snatch and fuck herself in earnest, but she resisted, even as she felt her pussy folds quiver in anticipation. Squinting, Maddy eyed the peephole to Elliot’s bedroom, making sure she was in full view if someone were to look through it from the other side. It was time.

“Mmmmmmf.” She started with a low moan as a hand delicately trailed down her tummy and under her skirt. There was no sign that she’d been heard.

“Ohhhh… ffffuck.” Maddy grew a little louder, bringing her other hand up to grope her own breast. This time, she heard a faint shuffling come from Elliot’s room. Was he wondering what he’d just heard.

“Mmmmmm, fuck me please….” Maddy maintained her current volume level. Little more than a whisper, but loud enough that the thin walls might carry her voice to Elliot. She started thrusting against her hand as she started fingerbanging herself in earnest. Come on… Come see your sweet big sister fuck herself silly for you, Elliot.

There. An almost imperceptible shadow moved through the peephole. Maddy knew what it was, Elliot was looking through. He was looking at Maddy while she had a hand down her skirt.

Maddy threw her head back and let out a louder moan, losing herself in ecstasy as she rocked her hips forward. Her other hand slowly started unbuttoning her uniform, revealing first one pert breast, then the other. Her fingers roamed over her hard nipples, pinching, rolling, and yanking. Her moaning got more intense. Fuck, I wish he were sucking on my tits right now.

A quick peek confirmed Maddy’s desires, the shadow at the peephole remained. Maddy closed her eyes, imagining Elliot spying on her. He must be sporting a raging hardon at this point. Was he still sitting there fully clothed, watching her while his cock strained against the fabric of his pants? Or was his underwear already around his ankles? Was he jacking off his cock while he watched his sister play with herself? Maddy shed her top now, fully revealing her perfect tits for Elliot’s pleasure. If he hadn’t already, he’d definitely started touching himself now.

Maddy was beginning to go buck wild with animalistic pleasure. The building threads of arousal running through her body were more intense than ever after not cumming for an entire week. She cast her panties aside and leaned back, giving Elliot a flash beneath her skirt.

“Fuck me! Oooohhhhh…” Maddy didn’t care that she was being loud. The thought of Elliot getting off to her performance was sending Maddy over the edge. She had to cum. Now.

Maddy threw herself onto her back, her chest arched. She fucked her sopping wet pussy with one hand while the other pinched and rubbed at her engorged clit. From his vantage point, Elliot would have the perfect view of her pussy while she fucked herself to orgasm. He must be getting close now too. He was watching his own sister fuck herself. Was he jacking off into her panties again? How many times had he cum into her panties, imagining that the silk fabric was actually her warm, tight pussy?

“MMMMMF!” Maddy’s hips bucked into the air as her orgasm came crashing in. Her mind was blanked of anything but the thought of Elliot jacking off his cock on the other side of the wall, shooting off ropes of cum into her already used panties. It was the most intense orgasm she’d ever experienced. Even long after the initial waves of pleasure wore off, Maddy lay there, too exhausted to move.

I hope you enjoyed the show, brother…

Knock. Knock. Knock.

Maddy suddenly leapt up, her heart pumping. The shadow at the peephole was gone. Someone was knocking at her door. As quick as she could, Maddy straightened her skirt and threw her dress shirt back on. Doing her best to look as unflustered as possible, Maddy answered the door.

There Elliot stood, his cock visibly straining against his jeans.

“Hey bro… W-what do you want?” Maddy stammered.

“I… I saw you, sis,” Elliot murmured. Maddy’s breath caught as he stared at her with lustful green eyes.

“Saw what…?” Maddy swore Elliot could hear her heart nearly beating out of her chest. Days of teasing. Days of aching sexual tension. And it was finally all coming to a head. Maddy bit her lip as her eyes trailed down to the cockhead that threatened to burst from her brother’s pants.

“I saw you touch yourself.” Elliot took a step closer, and something deep inside Maddy ached for release.

“Y-you were spying on me!?” Maddy drew her face into a shocked expression, even as she ground her thighs together in a bid for pleasure.

“I didn’t mean to,” Elliot said with the barest hint of a smirk. “You were loud as fuck.” Another step forward. Elliot was in Maddy’s bedroom now.

“You’re a fucking perv, you know that?” Maddy was breathing heavy, half out of mock anger and half out of barely controlled lust.

“I’m not the one who sent my sibling a naked selfie,” Elliot snapped.

“That was an accident, you fuck!”

“Sure.” Elliot’s eyes narrowed. “Just like it was an accident that you were fucking yourself in full view of that hole in our wall.”

Maddy bit her lip. Every ounce of her being was screaming to throw herself at her brother. To grab his face and kiss it deeply. To thread her hands through his soft hair. To stroke his thick cock with her slender fingers.

But that wasn’t the game Maddy was playing. She didn’t just want to fuck Elliot. She wanted her brother to take her.

And, so, as much as it pained her, Maddy rolled her eyes.

“You’re fucking disgusting,” Maddy spat. “I’m telling Mom!” Maddy made to move past Elliot, but she was blocked by Elliot’s strong arm. He held onto her wrist in a vice-like grip that made Maddy’s pussy moisten.

“What is your game?” Elliot said in a low tone. “Do you want to fuck your brother or something?”

Maddy pushed Elliot. Hard. Making him release his grip on her and back out into the hallway.

“You porn-brained psycho!” Maddy let actual, real tears creep into her eyes for this. She couldn’t help but be pleased with herself. “I-I won’t tell Mom about this just because I don’t want to ruin your life.”

Elliot’s eyes flared, trying to make sense of the emotions Maddy let flash across her face. Maddy held back a smirk as her brother’s eyes raked down her body once more.

“Sorry,” Elliot said after a pause. “I misunderstood…”

“You’re making me sick, Elliot.” Maddy internally cringed, hoping she wasn’t pushing him too far.

“It’s not like that, Maddy!” Elliot said. “I just, uh, figured I should shut this crap down if you really did have a crush on me or something.”

“Whatever, bro,” Maddy replied. “It’s no wonder you don’t have a girlfriend yet.”

And with that, Maddy slammed the door in Elliot’s face. She listened at the door for a moment, listening to his footsteps pad down the hall, then heard him collect his keys and leave through the front door.

Maddy finally slumped to the floor, exhausted. Turned out, it was hard work to not only seduce her brother, but also gaslight him into thinking he was the one coming onto her.

A thin smile played at Maddy’s lips as she thought back to the moment just before she shut the door on Elliot. How she’d been sure to glance at his crotch one last time before shutting him out. How she’d seen his erection still raging against the tight fabric of his jeans.

She slid one finger into her pussy as the thought of it lingered… then another.
