It was December 16th, and Sarah's fall semester was done. DONE. No more papers, no more all-nighters, no more pulling her silky blonde hair out, wondering how she would get through the semester. She'd made it through with three A's and two B's. Nothing to brag to the world about, sure, but nothing to scoff at either.
As she pulled into her parents' driveway, she breathed a massive sigh of relief. She'd been looking forward to the winter break since the semester started. The next four and a half weeks would be filled with relaxation and some work here and there, earning money for the next semester.
As soon as she slammed her car door, the front door to her parents' house burst wide open and Todd, her 18 year old brother, came jogging out.
Sarah smiled as she looked him over. He'd filled out considerably over the last few months. He was tall, lean, and handsome, just like his Dad. Always the friendly, social type, Todd was a hit with the ladies. When Sarah left for college, he'd just begun hitting the gym, and the results of the past few months were obvious.
"Hey, sis!" said Todd, smiling as he grabbed her bags.
"What's up, loser? You're looking pretty skinny. Weren't you supposed to be hitting the gym?" Sarah teased.
Todd rolled his eyes as he and Sarah headed inside. Todd followed Sarah up the stairs, easily shouldering both of the heavy bags. Before he knew what he was doing, Todd found himself staring slack-jawed at Sarah's firm, round ass as she climbed the stairs. She was wearing a grey, paper-thin pair of leggings, and Todd's heart skipped a beat every time she took another step up the stairs. He was hypnotized.
Shaking his head several times, Todd managed to clear his thoughts. As he dropped Sarah's bags in her old room, he chastised himself for looking at her that way. Todd shifted uncomfortably as he noticed the growing erection bulging from his sweatpants.
"She's your sister. Holy crap, man. Get a grip." he thought.
"So how are things with you and Amanda?" Sarah asked.
Todd shrugged.
"We broke up. People grow apart, you know? It's whatever."
Sarah frowned, shaking her head. She'd never liked Amanda. She pulled Todd in close for a bear hug, her eyes widening as she noticed something rock hard pushing against her stomach.
"Todd! Are you hard!?" Sarah giggled.
She backed away, blushing. There was no hiding it - a massive bulge protruded from Todd's crotch, and Todd moved to cover it with his hands. Sarah caught them and moved them away, laughing.
"What the hell, weirdo? What's got you so turned on, huh? Getting hard from the sight of your older sis?" she teased.
Todd was mortified.
"Well, if you'd wear something besides leggings for once, and keep your ass out of my face while I'm going up the stairs..." he began.
Sarah laughed again, her eyes flicking from Todd's crotch to his face.
"You were looking at my ass!? You're such a PERVE!" she yelled.
Todd just shrugged.
