That underlying tension had always been there, shifting and changing as they'd grown and matured. It had started out as simple house rivalry: she was Gryffindor and he Slytherin. Then it evolved into Quidditch and then on to develop the underlying sexual tension that had come to classify their interactions both on and off the pitch. It didn't really matter that they had only snogged a time or two, all that rivalry and competitiveness took the outlet for what it was and poured into it, creating that heat that burned between them when the chose to let go.
Her response to his taunting was enough of a open door for him, and he turned them, backing her up against the outer wall of the restaurant. He was unconcerned with who was watching or where they were. It mattered little in the grand scheme of things. If she wanted trouble, well, "Looks like you found it," he smirked, his hands sliding from her side to trail down her leg, his fingers digging into the back of her thigh as he lifted her leg around him and pressing himself closer as his lips found hers in a heated kiss. There was little chance a member of the media would venture down into the darker corners of Knockturn Alley, but if there was one brave enough, the picture they'd get would be hard pressed to find a lower rating suited to the publications.
It was a shame, she wasn't more of a dress girl. His fingers where itching to explore her skin and continued to be denied by the jeans she'd encased herself in. He might have suggested a change in location, but he was much to busy enjoying the feel of having her pinned between him in the wall, her body moving against his as he completely took over the kiss, letting the heat rise as it wanted to.

Years of suppressed sexual desire and denying that she'd ever wanted anything from him tended to blossom upward whenever he was near. This was a recent occurrence and while it wasn't awful... it wouldn't end well. The problem was that she just didn't seem to care. Not when his lips were moving expertly over hers. Not when he was kindling a burning need inside of her. She groaned when he pushed her against the wall, her head bouncing off the brick but she didn't even notice, too focused on what it felt like to have him surrounding her. This unhealthy little thing they had for one another was overwhelming. Merlin. She just wanted him inside of her. And she wasn't even drunk...
"Good," she murmured, letting him direct her legs apart, moaning his name when he settled against her. It was dark and quiet in Knockturn and she couldn't be bothered to be worried about anyone even noticing this. Her hand slid between them, grazing the hard bulge straining against his jeans. She smiled against his lips, loving that she was the one that made him hard. It was hot and heavy and she was Katie Bell. And she'd made Marcus Flint hard. If it wasn't so bloody hot, it'd be hysterical.
She broke their kiss, lips swollen, pupils dialated as she searched his face. This wasn't just a kiss... this was more than that. She wanted him in her bed. Or in his bed. At this point, she didn't care so long as it ended up with him inside of her. She lightly brushed her lips to his, taking a moment to calm herself. "Come home with me," she murmured, taking his bottom lip between her teeth. Lexi was pretty much out and in her own home and she was pretty sure there would be no one who would interrupt them.
