"oh." It was a small sound, breathy with the awe of him being so close. "Oh!" Louder now as the words sunk in and the pink became this apple red that spread from her cheeks and down her chest and probably a lot further as a dopey grin somehow comendeered her face and she just couldn't make it go away despite the panicked beating of her heart.
Tony Stark, playboy billionaire that had super models tripping all over themselves to be with him was asking her to... to... oh god he was asking her that. And he knew she liked Steve, who was his best friend and surely he wouldn't go after someone his best friend was interested in which meant Steve wasn't interested in her which was why he hadn't called and had probably asked the Sheild people to tell her he was unavailable just so he didn't have to tell her he wasn't interested in person and had hoped she would get the message and here she was sneaking into a party because she was so incredibly stupid.
Having little control over her features, never learning to hide her emotions, this whole line of thought played out on her face. From the silly grin to the confusion to the horrified shame to the simple sadness at realizing that of course Steve wasn't really interested in her to confusion again as she looked up and met Tony's eyes. Why would he be interested? Even in just a one night stand. She wasn't some glamorous woman with a pencil waist, she was just...
Who cared? She didn't want to feel that pain that clutched her heart at being told to get-the-fuck-out by Steve's best friend because he couldn't do it himself... because she wasn't worth it. Lorna forced a smile to keep the tears at bay and stepped in so she was inches from the older man, his beard tickling her cheek as she purred out in a tiny voice for their ears alone, "Tony, I'd love to see your car."
