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 drove 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.
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.
