Voyeur (ChipFic)

>Lupa grunted as she crawled through the vents
>The girl was getting too big for this
>She had a plan however, one she put into motion earlier that day
>Lupa had spent the last hour getting Lemy worked up
>It didn't take much, he was a boy going through puberty after all
>A quick flash of her thigh here, a peak down her shirt there
>Being a little sensual when eating a popsicle
>Her brother was red faced and pitching a tent that he did a poor job hiding as he retreated to his room
>All that was needed was for lupa herself to get into position
>And that was in front of the grate looking into lemy's room
>He was still struggling with his belt, eager for releaf
>As was Lupa, nothing got her as excited as this
>The dour girl lifted her hips and rested her head in the crook of her arm, biting down on her sweater
>Didn't want to risk crying out
>She snaked her hand down the front of her panties and traced along her slit
>Lemy had gotten started, pumping a furious pace
>He never lasted long when she got him this worked up
>And neither would she, as she bite down hard to supress a moan
>Lupa tried to match her pace to Lemy's, but her mind started to fog and her knees started to shake
>As much as she wanted to go to town on herself, she needed some self control

>She couldn't lose herself in the act and risk kicking a vent or moaning a little too loudly
>Getting caught here was not part of the plan
>At least not yet, she hadn't worked up the courage for that
>She very much wanted to climb out of the vent and offer him a hand
>Push him down and have her way with him
>or better yet, getting him so worked up he pushed her down and had his way with her
>As much as she hated to admit it, she was all talk, sexual stuff flustered the hell out of her
>Even teasing Lemy was almost too much for her, and required weeks of hyping herself up
>Lupa leaned to one side, only one eye open, struggling to take in the sight of her brother's "alone time"
>His hips were raising off the bed and he was biting his lip, he was close
>Lupa quickened her pace, she wanted to finish with him
>With a cry lemy exploded all over himself, ropes of white shooting over his chest
>Lupa bit down hard as her mind went blank
>She crossed her ankles to keep her spasming legs from selling her out as she rode out her orgasm
>Lemy's breathing slowed to normal and he reached over for a towel to wipe himself off
>The front of his shit was ruined, painted with his seed
>"Ah man, I liked this shirt." lemy sighed as he slipped it off
>Lupa made a mental note to steal that shirt as she slowly backed out of the vents
