Phineas and Isabella are 17 in this.
Disclaimer: I don't own Phineas and Ferb
Phineas stretched, placing an arm around Isabella's shoulder. "So… for our first date, where do you want to go?
Isabella placed her head on his shoulder and sighed dreamily. "Anywhere, as long as I'm with you."
"Well, we have dinner reservations at the new restaurant Ferb and Vanessa opened up at about 7, so we have the rest of the day free." Phineas smiled, starting up his car that he got for his 16th birthday.
Isabella snapped her fingers and opened the passenger seat door. She hopped out and winked at Phineas. "I'll be right back!"
Running into her house, Isabella clambered up the many steps to her bedroom. "Isa? You're back from your date early!" Vivian called up to her daughter, who had a rucksack slung around her shoulder and skipping down the stairs, two at a time.
"I just forgot something, mama." Isabella giggled, kissing her mother on the cheek. "Wish me luck!" Isabella ran back to the car and pratically dived in. The car soon drove off down the road.
"I wish you luck all of the time…"
"So, Isabella. Where are we going considering I'm not getting off of this roundabout and cars are looking at me funny." Phineas asked, making Isabella bite the inside of her cheek.
"See that shop there?" Isabella said, pointing to it. "Park in the car park."
Phineas did just that, parking gracefully next to a car with a head at the front. "Now what?"
Isabella laughed and wrapped an unused hankerchief around his eyes. "Unbuckle your seatbelt and get out of the car." It took Phineas a while, but he managed to do as Isabella instructed. She led him over to the passenger side of the car and helped him get in, buckling his seatbelt up. "I want you to trust me and not to ask questions, okay?"
"Okay?
"Now, stay here whilst I run into the shop to get a few things."
"What are those two doing?" Doofenshmirtz asked, glancing over at the car to see Isabella run into the shop
"It looks like they're on some sort of date." A girl next to him responded, messing up his hair.
"You know, I'm really glad that I reversed the effects of my inator so that you'd give me another chance. Now, I'm the luckest man in the world!" Doof cheered, doing a weird dance.
"And I'm glad that I'm not dating Rodney anymore." She smiled, snuggling up close to Doof.
Isabella came running back to the car, carrying nothing. She hopped into the drivers seat and slowly backed out of their parking space. "Hey, Sofia (the girl who he dated in Chez Platypus) should we follow them? I mean, wherever they're going it must be fun."
"Whatever you want, Sweetie." Sofia smiled, squeezing Doofs hand.
"Lets be stalkers!" Doof cheered. "After I go to the bathroom…" Doof ran as fast as he could into the supermarket to use the bathroom.
"Isabella? Can you give me a hint as to where we are going?" Phineas asked, turning his head towards her general direction.
"It's a surprise, Phinny! You're gonna have to wait." Isabella giggled, turning into a parking lot. "Okay." She removed the blindfold.
"This is your surprise?"
"Nope." She chucked him a pair of orange swimshorts. "Just put these on." Isabella got out of the car to give Phineas some privacy. He knocked on the windscreen and Isabella got back into the car.
"Why do I have to wear swimming shorts?"
"And a blindfold." She put the blindfold back on. "We'll be there in a few minutes."
"Face it, Doof. We're lost!" Sofia snapped, glaring at her boyfriend.
"We can always check a map to see what's around here." Doof mumbled, pulling out a map from the glovebox. "We could always go to the seaside. It's only a few minutes from here."
"Sounds like a plan." Sofia grinned, rolling down her window to let some fresh air in.
