Diaspro and Sky interaction at the Eraklyon Festival thing during sometime in season 2 or 3. AU because Bloom and Sky are not together, you could see this as a continuation to chapter 1 about the Day of the Royals.
Diaspro smiled as she approached her prince, holding her breath in anticipation. It had been months since she'd last seen him, it had been shortly after the Day of the Royals that had been the last time they'd been able to spend time together.
She felt her heart skip a beat when he turned and saw her. His smile lit up the dark night, and he looked mesmerized as he watched her approach. His eyes explored her as she neared enough to see more clearly in the dark of the evening. Red was her color, she'd always known this of course, but Sky, oh Sky just loved her in red. His eyes devoured her, and his lips were turned up into a possessive smirk as she handed him a tall glass of Eraklyon's finest wine.
"Princess." He leaned closer, as if there weren't anyone else in the vicinity.
"My prince." She relished the attention he directed towards her, it delighted her to know that he missed her just as much as she missed him. "I've missed you." She admits as she sips the decadent drink.
"I wish I could have come home sooner." He replies, "It's been an adjustment going back to Red Fountain, and to be quite honest, I would have rather spend my time here with you."
She couldn't help the light blush that traveled across her cheeks and was thankful that even with the glowing party lights around them, it was still too dark for strangers to see. But Sky, he grinned at her and leaned closer to whisper to her, "Such a lovely color on you." As he trailed cupped her cheek and trailed a thumb across the blush quickly. "Only for you." Her reply was rather flirtatious, she would admit, but it just kind of came out.
"Would you care to dance?" he asked her, taking both of their glasses to deposit them on a waiter's tray without waiting for her answer.
She raised an eyebrow, "Mighty confident I'll say yes, are we?"
"Would you really turn down the chance to dance with me?" His eyes twinkled even as he pretended to look hurt.
"No, never." She laughed with a teasing smile.
She was grateful that dancing was meant to be close and she got comfortable in his embrace right away, leaning into his touch as they slowly twirled to the live music of the band. Her eyes linger on his lips before looking up to his eyes. "I want you to kiss me." She tells him as they come to a stop and inclines her head just slightly, the nonverbal invitation to match the verbal request.
She knew the fact that she was wearing red lipstick to match her red dress would be tantalizing, and she was a little surprised he hadn't kissed her sooner, but she didn't dwell on it as he glanced around before moving impossibly closer, his hands cupping her face gently as he tilted her head father as he brought his own face down so their lips could meet. She knew they weren't supposed to be so public with affection like this, at least not until after their engagement was publicly announced, but she couldn't bring herself to care as she wanted nothing more than a kiss.
