Colleen and Braden are both high school seniors, with just a few months before they go off to college, and both of them wished they'd decided to ask the other out before now. They'd been friends through school, and both had been more than interested in the other, but it seemed like whenever one of them was single, the other one was dating someone.
That had finally changed when Braden's girlfriend had broken up with him right after prom; honestly, he had suspected that if not for prom, she would have dumped him in March, but she wanted to hang on for the big dance. Anyhow, for the first time since they were in middle school, Colleen and Braden were both single at the same time, and Colleen hadn't waited for Braden to get over Julia; she'd suggested they should go out for coffee or something, and he'd dropped by that same night.
She'd worn a knee-length summer dress that was a little bit cold for the evening, but perfect for her goals. And after the fourth kiss, sitting on the hood of Braden's car, she felt quite warm indeed.
"So," Braden said, "you said coffee...should we...."
"You know," Colleen said, tossing her red hair back just so, "I probably should have mentioned, but my parents are out of town this weekend, and my sister's at her friend's house tonight...and my parents do have a Keurig...."
Braden was an honors student; he didn't have to ask what Colleen had in mind. As they hopped down, he slid his arm around her waist; she was barely aware of the feel of some dirt between her toes, but she was far too enthralled with the feeling of his hand on her hip to notice little you.
You, meanwhile, were being shaken with every step, her toes squeezing tight around you. You had expected the two lovebirds would get in the car, but instead they were walking down the street some more, then up a step, then another, and then a pause at the door as the girl put her key in the lock.
You looked up, getting a tremendous view up her short skirt; soon enough, the door was opened, and the movement continued, with Colleen pausing to unfasten her sandals.
You aren't particularly secure, and fall out of the gap between the toes as she removes the sandal on the foot where you're hiding. She steps forward, kneels again, and undoes the second one.
You don't have a lot of time if you want to stay with the girl; if you run, you could get to her feet before she starts walking again, though you're not sure how well that would work, or if she'd feel you. You also could try to grab the hem of her skirt -- it was just hanging above the floor, and while you'd have to jump for it, you thought you could get there.
Then again, you could always let her and her boyfriend get on their way; you could grow a bit and find your way to them, and shrink back down if you needed to hide.
You'd better do it quick, though, she's almost got the second sandal unbuckled.
