Casual kisses. It's their thing. It didn't mean anything; really, it was just a way to relieve the tension between them. Adrien could still flirt with Ladybug, and Marinette could start moving on from Adrien. They were helping each other; it was completely harmless.
No harm, no foul, right?
Adrien pressed Marinette against the wall, panting heavily into her ear. He could barely see the outline of her shapely body within the dark supply closet, but he could most definitely feel it.
"Does this mean anything to you? About us?" Adrien whispered hoarsely to her, his voice rough from his want for Marinette. He kept her caged within his arms; to keep this moment between them and them only. He littered her collarbone and bare shoulder with butterfly kisses, lips only making contact with her skin for a brief second before moving to a different spot.
He couldn't feel the internal pain that Marinette felt; rather, he felt her nails rake down his clothed back. Adrien released a low groan, pulling away from her neck and gazing into her cerulean eyes. He looked at her with, was that hope? No, that was Marinette's overactive imagination.
"No." Marinette answered finally, pulling him in until their lips met once more.
