I'm finding it hard to write my sequel to Rock Steady, so instead of just hunkering down and doing it, I wrote this very, very short one shot. It's a bit of a missing moment, from the epilogue chapter, Across the Sky in Stars, in City of Glass. It's not very serious either, but I like fluffiness sometimes.

He let her go at last and she gasped—she'd forgotten to breathe. He cupped her face between his hands, tracing the curve of her cheekbones with his fingers. The light was back in his eyes, as bright as it had been by the lake, but now there was a wicked sparkle to it. "There," he said. "That wasn't so bad, was it, even though it wasn't forbidden?"

"I've had worse," she said, with a shaky laugh.

"You know," he said, bending to brush his mouth across hers, "if it's the lack of forbidden you're worried about, you could still forbid me to do things."

"What kind of things?"

She felt him smile against her mouth. "Things like this."

City of Glass, pg. 533.

His lips brushed hers lightly again, before he pulled away momentarily. The second time his lips came down onto hers they weren't so gentle. Jace kissed her with an intensity she had never experienced with him before. There was no holding back, and soon Jace's tongue was sweeping across Clary's bottom lip, asking for permission. Clary obliged happily, savouring the sweet taste of Jace's tongue in her mouth.

Her fingers traced themselves up his back, feeling the contoured muscles moving as his arms wrapped around her back and neck. Jace shifted his arms again slightly, one of his hands making its way into her curly hair, the other onto her right hip. Clary adjusted her body, melding herself into Jace. Her grip on his back tightened, and still, she felt like they weren't close enough.

Removing his lips from her mouth, Jace started a hot, wet trail of kisses down her chin, onto her neck, and only stopping until he reached the top of her breasts. Clary moaned lightly at the sensation his mouth was having on her skin, tiny goose bumps erupting from her excitement. She let her hands drop right down to his butt, gripping it firmly, eliciting a low growl from Jace.

"That might have to be forbidden," he mused.

Clary smirked. "But I like it. And I thought I was the one doing the forbidding."

"We may have to make some exceptions," he said, while taking her mouth with his again. There was a passion in this kiss that she remembered feeling when they kissed outside the Wayland manor, raw, deep, and very hot. His hand moved from her hip, his fingertips slowly trailing up the soft fabric of her dress, stopping only when they reached under her left breast. His thumb slowly moved against her nipple, causing it to harden right away. Clary gasped at the feeling. He stopped kissing her, looking into her eyes to see if she had any worry in them. Clary only put her hand on top of his, moving it up to fully grasp her breast.

Jace let out a long breath that he must have been holding, while simultaneously moving his other hand down onto her second breast. Giving them both a little squeeze, Clary suddenly laughed. Not what he was expecting, Jace dropped his hands.

"What did I do?" he asked seriously.

Clary only laughed more. "Nothing! It's just funny, that's all."

Jace frowned. "I didn't think this is funny."

"Jace," Clary crooned, "you're feeling me up. It's kind of funny."

Whatever Jace was going to respond with never left his mouth, as a single firework shot up into the sky, announcing to the inhabitants of Alicante that the show would soon start. Clary kissed him once more, before pulling him along behind her, back to the others. There would be plenty more time for them to be alone. They had the rest of their lives.
