A/N: Hey! Huge thanks to my No. 1 Reader and Gigglebox15 for the reviews to the previous chapter!
Here's a new plotbunny... Wow! The tenth chapter already?
Enjoy!
I don't own Phineas
and Ferb.

"And she was like 'Oh, no, you didn't!' and I was like 'Oh, yes, I did!' and..." Isabella was talking to her friends, the former Fireside Girls. They were all at Isabella's house, chatting and having fun together.

Suddenly, she heard knocking on the front door so she stood up and left, saying she would be right back.

"Oh, hi Phineas!" the girls heard her exclaim cheerfully.

"Hi, honey," they heard his response and a quiet smack. They looked in shock at one another and fell absolutely silent.

Phineas and Isabella entered the room, holding each other close, and noticed all six girls staring at them curiously.

"Hi, guys," he greeted them with with a smile.

"Hi, Phineas!" they replied in unison.

"So... I see that you are finally together?" Ginger asked with a smirk, seeing them embrace.

"Yes, yes we are," Phineas and Isabella replied at once and smiled warmly at each other.

All the girls cheered enthusiastically and congratulated them.

"Oh my gosh, I still can't believe it!" Adyson said. "I want you to prove it!"

"Adyson, really? Prove it? How?" Isabella sent her an "aw-come-on" look.

Adyson just wiggled her eyebrows. Isabella understood what that meant, and blushed.

"What? But we haven't... you know... yet."

"Then I don't believe you," Adyson smirked even broader.

"Oh, please, you've got to-" she stopped, surprised, when she realised that Phineas kissed her. But this time it wasn't just a peck on the cheek, it was a full, long kiss. She melted into this immediately. As soon as they broke it, she gazed deeply into Phineas' eyes and smiled dreamily.

Adyson exclaimed, "See? That was the proof!"
