It was early. Lucca, the self-proclaimed awesome scientist, had been up all night working on her latest invention. She was walking from the kitchen to her lab, just finishing her short break. Lucca wore her usual thick, round glasses and dark green shirt. And out of laziness, only a pair of bright orange undies covered her moving cheeks. Lucca's butt was firmed by years of running around the lab at a hectic pace, due to every malfunction and explosion you could think of. That toned rear end she sported was a round, petite little thing. It still definitely made for a comfy cushion.
Lucca entered her lab; it was filled with piles of broken gizmos and gadgets. It was a complete mess. Lucca went to her work bench, and perched herself on top of a stool. Her snuggly-fitting panties slipped down a pinch as she sat; her cute little crack peaking out from the top of the waistband.
