I don't own Phineas and Ferb.

The door slammed, announcing Phineas and Isabella's return to the two families' dinner. Because frankly, when they had decided to take a brisk walk, nobody dared convince them to stay; instead, everybody's gazes followed the departing pair with slight snickers. Both of their mothers sighed in disbelief. Just a short walk together, their kids said. How can these two be so oblivious?

Now that they were back, their relatives in the living room fell absolutely silent. They could only hear Phineas and Isabella's lively, muffled conversations coming from the other room. Isabella giggled and, for a while, there was perfect silence. Everyone sent one another intrigued looks.

Meanwhile, in the hall, Phineas was just helping Isabella with her jacket. As he hung it on the coat hanger, he turned back to her with a broad smile.

"I don't wanna go back there yet," he admitted.

"Me neither." Isabella smiled back. "I just wanna... relive it for a bit longer."

For a while, they fell silent, processing recent events.

"You know..." he started. "It's amazing. Since we kissed... I've been thinking only about it."

It was true. Since approximately the middle of their walk, his mind was filled with nothing but thoughts about her and the kiss. How did it happen? At one moment, she made him unable to think of anything other than her. Her eyes, as joyful as never before, her smile, never as certain as then, her lips, which he still remembered upon his, her scent, her taste... His mind and all his senses were occupied with her. He still wasn't sure how it was possible, which left him simply standing there in wonder about what power just one close moment with a person you love has.

"I'm so happy you say so," she said quietly. "Me too, I'm just... trying to remember everything that happened as well as I can."

The things they felt were completely stunning. For the two young people, these emotions were so new and intense, they were having a hard time understanding and processing them all. They both had supposed that their first kiss would be a huge experience, and yet this had knocked over their boldest expectations.

Because every time you find yourself in a new situation, it makes you come through it many more times as carefully and attentively as usual, leaving an unforgettable mark on your mind. You always remember the atmosphere and accompanying emotions that were building up inside you. When it comes to something as memorable as the first kiss, you are no longer in control of your emotions; they just cunningly free themselves from all your restraints, making you barely keep up with their pace. You can just try to recognise, catch, and preserve them all in your memory before they pass away unnoticed.

That was why Phineas and Isabella kept reliving their kiss over and over again in their heads - because every time they thought about it, they discovered something new, which they had failed to notice earlier. Phineas remembered how Isabella's lips had curved into a small smile at one moment, and smiled broadly at her again.

She giggled warmly, then leaned in closer to him, planting a small kiss on his lips, stealing all of his mind's attention, focusing it on her again.

She pulled back after a couple of long seconds. As if on an unspoken agreement, they finally decided to return to their families.

"Ready to struggle to act naturally?" Isabella asked, laughing.

"Who are we kidding, Isabella?" He chuckled.

Walking out, they almost bumped into Linda and Vivian, who decided to check on their kids.

"Hello, sweethearts!" the mothers greeted the pair.

"So, how was your walk?" asked Linda.

Phineas and Isabella shot a quick glance at each other. Their cheeks were flushed, their eyes sparkling, their voices unnaturally excited. It was so extremely obvious.

"Awesome," the two simply replied in unison, with broad smiles.

They noticed their mothers' expressions.

They totally knew.

That's what happens when I stay up till midnight to finish a story... :P Anyway, thanks for reading and please review!
ElleFreak is out, peace!
