Naked and Unafraid: A PHINEAS AND FERB Romance

Naked and Unafraid: A PHINEAS AND FERB Romance
by George Glass

Summary: When Phineas and Isabella accidentally inhale a formula that suppresses fear, they make their true feelings known. Unsure of what to do next, they decide to let instinct take over—and boy, does it ever. (Phineas/Isabella, rom, gettin' it on)

Disclaimer: I do not own PHINEAS AND FERB or its associated characters. I received no payment for writing this story.

Warning: This story involves two 11-year-old cartoon characters making sweet, sweet love (not down by the fire, because it’s PHINEAS AND FERB and therefore summertime, but you get the idea). If that’s not your thing, you know where the Back button is. Otherwise, read on!

---

It was the middle of the morning, and Phineas was in the family room, surrounded by glassware, tubing, and jars of chemicals from Ferb’s chemistry set. He held a test tube up to the webcam that he had earlier set up on top of the television.

“Okay, Ferb, I just added the final ingredient,” Phineas said to Ferb’s image on the TV. “Should I go ahead and put it in the agitator?”

Ferb nodded, so Phineas put the test tube into a small, cylindrical machine that was sitting on the coffee table. He was just switching the machine on when the doorbell rang. Phineas opened the front door to reveal a familiar face.

“Hey, Phineas,” Isabella said musically. "What'cha dooin'?"

"Not much. Ferb and I spent the first hour of the morning building a fifteen-foot-high statue of the Duke of Wellington out of marshmallows, but-"

"The Duke of what, now?"

"The Duke of Wellington. He defeated Napoleon at the Battle of Waterloo, and he used to be on the British five-pound note." Phineas grinned. "You learn a lot when you're Ferb's brother."

“Well, I guess that explains the puffy white giant with all the gold braid that I saw when I was looking for you in the back yard. So what are you up to now? And how come you’re doing it in the living room?”

“Poor Ferb’s got the stomach flu,” Phineas explained. “He’s stuck in our room while Mom is picking up some medicine for him. It’s really too bad—we were going to try to set our personal record for most projects completed in a day, but Ferb got sick right after we finished the Duke. Even wiring up the TV so we can teleconference isn’t helping us catch up, especially since Ferb keeps having to run for the bathroom every few minutes.”

Phineas turned to the television screen. Ferb’s face, previously a pale green, now somehow seemed both paler and greener. The boy’s lids drooped over his mismatched eyes.

“Ferb, do you need a break?”

Ferb nodded slowly, apparently not wanting to move his head around too much.

“Why don’t you go lie down? I can finish up here.”

The television screen went gray.

“Gee, poor guy,” said Isabella. “So what are you mixing up, here?”

“Well, yesterday we overheard Candace saying that Jeremy’s uncle is building a second restaurant, and Jeremy invited Candace to come to the opening. But the restaurant is on the top floor of Danville Tower, and Candace is scared of heights, so we’re making her a formula that temporarily suppresses fear when you inhale it.”

“Is that why I smell vanilla?”

“Yeah, it’s Candace’s favorite scent.”

“Did you spill it or something? It’s pretty strong.”

“No, I don’t think…oh no!” Phineas dashed to the agitator and turned it off. Then he opened the lid and looked inside, frowning.

“Gosh, I think I bumped into the knob and turned the agitator up too high when I went to answer the door. The test tube is shattered.”

“Oh, no,” said Isabella. “I’m sorry.”

“It’s not your fault,” Phineas replied. “And at least the formula got really well mixed. I can probably pipette what’s left into a vial for Candace.”

“That’s good. Then what?”

“I don’t know. Ferb and I were going to mold sleds out of ice so you can go sledding on any surface you want, but I guess that’s not going to happen. Sorry—I wish we were doing something interesting."

"That's okay," Isabella replied. "I mostly came over because I'm totally in love with you and I like seeing you every day." Isabella’s eyebrows rose in surprise. "Wow—I can't believe I just said that!”

“It might be the formula,” Phineas mused. “We’re breathing it in right now. But why would it make you say that? Maybe it interferes with emotions other than fear. I should check the molecular-”

“No, no, it’s not that. I think the formula is keeping me from being afraid to tell you how I really feel."

"Gosh. So you’ve been in love with me for a while?" Phineas said.

“Yes, and you’ve been completely oblivious to it, which has been CRAZY frustrating!”

"I’m sorry, Isabella. But maybe that explains it."

"Explains what?"

"Well, lately, whenever you're close to me, I’ve been feeling kind of lightheaded, and I get a funny feeling in my stomach.”

“Really?” Isabella squeaked.

“I thought maybe I was allergic to one of your hair products, but...is that what love feels like? Boy-girl love, I mean; I already know what boy-family member and boy-platypus love feel like."

Isabella's eyes seemed to sparkle, and a huge smile spread across her face. "That's exactly what it feels like," she answered.

“Wow. I was wondering why being dizzy and kind of queasy somehow felt good. But I guess it makes sense; I mean, you’re an amazing girl.”

“Oh, really?” Isabella said with a sly smile. “Tell me more.”

“Well, you’re smart, you’re fun to be around, you can do pretty much anything you set your mind to, and you’re cuter than current technology can safely measure.”

Isabella’s smile faded into a skeptical frown. “Hang on a sec. I have to check something.”

She pinched herself hard on the arm and winced from the pain. Then, strangely enough to Phineas, the smile returned to her face, brighter than ever.

“I’m awake. This is really happening,” said Isabella, her cheeks turning pink as she started to hyperventilate.

“Are you okay? I hope you’re not having some kind of bad side effect from the formula.”

“No, no,” the girl gasped. “It’s just excitement….Having your biggest dream of the summer suddenly come true is …kind of intense. It’s a good thing I can’t feel anxiety right now, or…the combination would probably make me pass out.”

“Do you want to sit down?”

“No, I’m good,” Isabella breathed. “So you’ve really never noticed that I’m into you?”

“Well, I guess you DO come over a lot…and you DO give me a sort of big-eyed look all the time…and you’re always finding reasons to touch me…,” Phineas said thoughtfully. Then his face fell in realization. “Wow. I’m kind of thick.”

“Yes, yes you are,” Isabella said with a smile as she took a step closer to Phineas. “Especially since you thought the way you felt about me was an allergic reaction.”

“Well, Candace is always saying that I don’t know anything about girls or love or romance. Maybe she’s got a point.” Phineas scratched his head. “Come to think of it, if we are in love, I’m not exactly sure what we’re supposed to do now.”

“Well, I’m no expert, but I’d say we should hold hands while we talk about it some more.”

“That works for me,” Phineas said as Isabella took his hand. “So what’s next?”

“I’m not sure,” Isabella replied. “When this happens in my head, you usually turn into a centaur and we run away together.”

“A centaur?” Phineas replied. “Well, I suppose if I got some horse DNA and rigged up a-“

“No, no,” Isabella interrupted. “I like normal, bipedal Phineas just fine.” Then her eyebrows rose.

“Hey, I actually DO know what we should do now,” Isabella said confidently. She moved closer to Phineas and planted a big kiss on his lips.

“Wow!” said Phineas. “I always wondered why people like doing that. It feels really nice.”

“It sure does! Wanna do it again?”

“You bet!”

They kissed again, this time for a little longer, and then again, and again.

Suddenly, Phineas began to fall over backward. Isabella threw her arms around him just in time to keep him from landing painfully on the coffee table.

“Thanks,” Phineas said.

“What happened?”

“Well, because of the shape of my head—and because you're a little taller than me—I have to tilt it way back to kiss you, and I guess I lost my balance.”

“Oh, I get it.” Isabella thought for a moment. “How about we try it sitting on the couch?”

“Good idea,” Phineas replied.

They sat down on the couch and kissed again. This time, Isabella opened her mouth a little, and Phineas did the same. After nearly a minute, they broke off the kiss to take a breath.

“Whoa,” Phineas said, “that feels really good. What made you think of opening your mouth like that?”

“I didn’t exactly think of it,” Isabella replied. “I guess it was just instinct.”

“Hey, maybe THAT’s what we should do today,” Phineas said. “We should follow our instincts and see where they lead us.”

“Sounds good to me. And my first instinct is to kiss you some more.”

“I think my instincts would like that.”

They kissed again, and Phineas pulled Isabella closer as the kiss became more forceful, more passionate.

Suddenly, Phineas got the urge to put his tongue in Isabella’s mouth. It seemed like a strange thing for his instincts to tell him to do, but who was he to argue with Mother Nature?

Isabella startled momentarily when the tip of Phineas’s tongue touched hers (in doing his background research for the formula, Phineas had read that surprise was a separate emotion from fear), but then her own tongue responded enthusiastically, exploring him just as he was exploring her. She put her arms around him, pulled him down on top of her, and wrapped her legs around his waist.

“Instinct again?” breathed Phineas when he came up for air.

“Uh-huh,” Isabella panted. “I feel like I need to be as close to you as possible.”

“Yeah. Me too."

She pulled him to her, and the kissing began again.

***

Upstairs, Candace was lying on her stomach on her pink bed, chatting away on the phone with Stacy.

“Dad is working and Mom is at the pharmacy, so I’m in charge. You know, by default.”

“Uh-huh,” Stacy said with a minimum of interest.

“But that’s not the best part. Ferb is in quarantine, which means nobody’s building ANYTHING today. I’m totally freed up!”

“Well, Phineas could still be up to something, right?”

“Nah,” said Candace. “What kind of trouble can he get into without Ferb?”

***

“Isabella, do you want to be on top for a while?” Phineas panted.

“Okay,” the cute girl replied. As they said up, she asked, “Can I take your shirt off first?”

“Sure,” Phineas replied, obligingly holding up his arms. Isabella pulled the orange-and-white striped shirt over Phineas’ triangular head and off. Then she looked at him and grinned.

Phineas said, “I know my body’s not exactly-”

Isabella cut him off. “It’s perfect,” she said, laying a hand on his conical cheek. “You’re perfect, Phineas.”

Gently, Isabella pushed Phineas down until he was lying on his back. Then she climbed onto him, straddling his hips. She had intended to lie down on top of Phineas to kiss him some more, but she was distracted by the feeling of Phineas’ erect member directly under her groin. She didn’t know what excited her more—having nothing but a few layers of fabric between her private place and his, or the fact that SHE had been the one to give him the erection he was sporting now.

Instinct told her to move, to increase the sensation, so she began gently rocking her hips forward and back, rubbing her genitals against his. Her hands rested on Phineas’ warm chest as the boy smiled up at her with a mix of adoration and pleasure.

“Wow,” he breathed.

“Yeah.”

Phineas put his hands on Isabella’s bare knees, then slowly slid them upward, under her skirt, all the way up the outside of her thighs.

“Ooooh,” Isabella sighed.

“I want to touch you all over,” Phineas explained, his voice becoming hoarse with desire.

Suddenly, Isabella realized what her instincts were telling her to do next.

“Do you want to take my dress off?”

“More than anything,” Phineas breathed. Then his face clouded. “Do I just pull it up from the bottom, or is there a button or a clasp or-“

“Just pull it over my head,” Isabella said, holding up her arms. Phineas obliged.

Once Isabella was free of her dress, she lay down on top of Phineas, savoring the feel of his bare chest against hers. His arms went around her, and she sighed happily. It didn't matter that it was 10:30 am on a Thursday; it didn't matter that they were in the Flynn-Fletchers' living room; it only mattered that she was with Phineas, holding him, loving him up close instead of from afar.

Soon, Phineas' hands began moving slowly up and down Isabella's back, exploring new territory. Isabella's instincts kicked in, and she started kissing Phineas' neck. Soon, she was working her way up the side of it, kissing, licking, nibbling, growing more aroused by the moment.

"I want to..." she whispered incoherently into Phineas', unable to fully express what it was she wanted to do. "...Let me..."

"Oh, yes," Phineas gasped. His hands moved over her body more ardently now, covering every inch of her back and then moving down to grasp her little bottom through her panties. The sensation made Isabella lose control, and where she had been nibbling on Phineas' neck, she bit him.

"Yowch!" the boy cried.

Isabella pushed herself up. "I'm sorry! I didn't mean to hurt you."

"It's okay," Phineas gasped. "I was just surprised. Well, mostly," he said, rubbing his neck.

Isabella could say the same. Here she was, alone and half-naked with Phineas, and she was turning cannibal? What kind of instinct was THAT?

But she knew that wasn't it. She just wanted Phineas so much that it felt like she needed to devour him.

"How about we turn on our sides?" Phineas said.

"Okay."

They turned, leaving about a foot of space between them. Now they could look at each other's bodies, and each had a hand free to touch with.

Phineas reached over and put his hand on the side of Isabella's face, then moved it down her neck, over her shoulder, and to her chest. Isabella gasped as his fingers brushed over one of her slightly puffy brown nipples.

"Does that feel good?" Phineas asked. "Because my instincts seem to want me to touch you there."

"Uh-huh," Isabella breathed.

Phineas ran his fingers lightly over her nipple, moving in a little circle. Breathing hard, Isabella used her free hand to caress Phineas' chest and side.

Then Phineas' hand slid slowly down her stomach, over her cute, circular navel, and cupped her private place through her panties. Isabella felt a rush of feeling down through her stomach and into her groin.

Phineas moved his head closer. "My..." he breathed, "my instincts say..."

He shifted his body downward, and suddenly his lips were on Isabella's nipple. She cried "Oh!" and clasped the boy's head tightly against her chest as he kissed, licked, and sucked her now erect little bud, all the while gently massaging her vagina through her panties.

"Oh, don't stop!" she gasped, "Don't ever ever stop!"

She could feel his hardness against her leg, and she instinctively darted her hand down to grasp it, caressing it through his shorts. In response, Phineas' free hand moved to Isabella's back and inside her panties to fondle her bare bottom.

It was like her whole world was nothing but Phineas and the sensual pleasure he was giving her. Rational thought was gone; she felt only need—need for him, for his body, for HIS need for her.

He pulled away and looked in her eyes. Their connection was like nothing Isabella had ever felt—intimate, intense, unbreakable.

"Do you...," Phineas gasped, "...want to take off...the rest of...our clothes?"

"Oh, yes," Isabella said. She pulled off her underwear so fast she nearly ripped them. Then her fingers joined Phineas' in fumbling at the button and zipper of his shorts and then yanking them down along with his Spider-Man briefs.

They took a moment just to look at each other. What was happening was almost literally incredible, and they both wanted to take the time to grasp it, to appreciate it.

"Wow," said Phineas. "We're really naked together."

"We really are," Isabella squeaked. She had never imagined that this would happen any time soon. Dreamed, certainly—even fantasized once or twice—but never imagined.

"I guess we're a little young for this, huh," she said.

"Yes...yes we are," Phineas admitted, still breathing hard. "Do you...do you think...we should stop?"

"My brain says yes," Isabella gasped, "but my instincts...say no way."

"Mine too...It's like...like they're so strong that...I can barely control them."

"Don't try," Isabella breathed sweetly, putting her hand on Phineas' face again. "I think my instincts...want…what yours want."

"Oh, Isabella," he gasped raggedly, then threw himself on her, kissing her hard. Isabella wrapped her arms and legs around him and thrust her tongue into his mouth to wrestle madly with his. Her instincts were practically screaming at her: hold him tighter! closer! deeper! more Phineas! more more MORE!

She grabbed his bottom and pulled his hips hard against her thighs, feeling the heat of his erect penis against her bare slit. In a more lucid moment, she might have remembered what she knew about sex and what parts went where, but everything she knew on only an intellectual level was forgotten in this moment; she only knew that she wanted it somehow, NEEDED it. She reached down and grabbed it, rubbing it forcefully against her vagina.

Phineas gasped, breathing even harder than before. Then he pushed himself up to look her in the eye.

"I want..." he breathed, "I want to put it...inside...."

Inside. That was the magic word. Inside!

"Yes," Isabella gasped, "yes!...I want you to...do that."

She spread her legs even wider and, keeping hold of Phineas' penis, guided it to her entrance.

"Push," she breathed. "Push it in."

Phineas closed his eyes and thrust into her.

"Ow! What the heck?!" Isabella shouted.

Phineas pushed himself up. "What happened? Are you okay?"

"I forgot this is supposed to hurt the first time," Isabella said with some irritation.

"We don't have to do this if you don't want to."

The formula was still in effect, so even though Isabella could feel pain, she was incapable of being afraid of it. Not that she would have been anyway—at least, not enough to stop this beautiful experiment with Phineas.

"No," she said, "let's try again. Just go slow this time."

Phineas positioned himself again and eased into her. Isabella felt a burning sensation as Phineas' penis stretched her from within.

When he was fully inside her, Isabella said, "Just stay still for a minute so I can get used to it."

"Of course."

Isabella wrapped her arms around Phineas and just held him.

***

Lying on top of Isabella, his head next to hers, Phineas couldn't believe how good it all felt. He was literally immersed in her—the sweet smell of her hair, the softness of her cheek against his, the heat of her bare skin, and most of all the tight, hot, loving sensation of being in her. It was like he was bathing in the essence of her, and he loved it.

"Wow," Phineas breathed. "You're so WARM inside. I mean, I knew that already, but I didn't know it was a physical thing, too."

“This is wonderful,” she half-whispered, half sighed into his ear as her arms tightened around his waist. “All summer long, I’ve wanted you close to me, and now you’re INSIDE me."

"Does it hurt less now?"

"Oh, yes. The pain's all gone."

Phineas smiled and held her tighter. "Good. Because my instincts want me to start moving around in you."

"That sounds...good."

Phineas began moving his hips very slowly, pulling himself partway out of Isabella and then pushing in again. They both gasped at the sensation.

"This is like..." Phineas breathed, "like nothing...I've ever...EVER..."

"Uh-huh," Isabella sighed. "Just...don't stop..."

Phineas didn't think he could stop if he wanted to. He held onto Isabella and just pushed in and out of her, over and over again, savoring every sensation as he moved inside her.

"I love this," Isabella whispered in his ear.

"I...I think I...need to...go faster..." the boy said.

"Wait," Isabella breathed. "Push yourself...up a little...I want...to look...in your eyes."

Phineas did as she asked, propping the upper half of his body up on his arms so that he and Isabella were face to face. Isabella reached up and touched his cheek.

"Sweet, wonderful, beautiful Phineas," Isabella said, gazing at him with total adoration. "I’ve loved you so much that it hurt."

Phineas looked confused. "But...but I don't want it to hurt."

"It doesn't anymore," she whispered. "Right now, everything I feel is good. So very, very good."

Phineas never took his eyes off Isabella's. "I'm really glad," he said. He wished he had more words, better words, for what he was feeling, but nothing he could think of seemed adequate. But maybe that was okay.

"Now," said Isabella, "follow your instincts."

"Oh, yes," Phineas said, his voice growing hoarse as his body flooded with need once more.

He began thrusting in earnest, and Isabella soon began to move her hips rhythmically in response, maximizing the penetration. All thought left Phineas as instinct truly took over; he grasped her tightly and thrust into her again and again and again, needing this, needing HER, needing to be deep inside her.

"Yes, yes, yes," Isabella whispered mindlessly into his ear. "So good, so good, so good!"

Phineas went faster still.

"I feel like..." he gasped, "like...like I'm going to..."

"Yes! YES! I love this I love YOU!" Isabella screamed, and suddenly her vagina squeezed Phineas tightly as she let out a long, impossibly high-pitched scream of ecstasy.

"YEEEEEEESSS!" Phineas hollered, thrusting deep into Isabella and holding her tight as he came with her.

There was a long moment when Phineas' mind and body were filled with ecstatic pleasure like he'd never felt before. Then he collapsed on top of her, breathing harder than he ever had in his life.

***

"What the heck was THAT?" said Candace. A dual scream had just issued from downstairs. One sounded like Phineas; the other was like a slide whistle in a wind tunnel.

“Stacy, I just heard something weird downstairs. I’m gonna have to call you back.”

***

Phineas smiled at Isabella as they lay naked in each other's arms.

"Wow," said Phineas. "I don't remember the last time I felt this relaxed."

"Or this happy," Isabella said, running a finger down his cheek.

"This whole summer has been like some kind of blockbuster movie," said Phineas. "Action, adventure, mystery, more musical numbers than seem possible, and now an epic romance."

"Totally epic," agreed Isabella.

***

Candace stalked down the stairs, annoyed at having to cut off her conversation with her best friend. As she reached the first floor and turned toward the living room, she snarled, “Phineas, what the heck is going oAAAAAAAH!”

There on the couch were Phineas and Isabella in a casual but romantic embrace. And buck-bare naked.

“What are you two DOING?!” Candace cried as she slapped a hand over her eyes.

“Hey, Candace,” Isabella piped, snuggling closer to Phineas.

“Oh, hi, Candace!” said Phineas said cheerfully. “We just did the most amazing-”

“For crying out loud, don’t DESCRIBE it!” Candace hollered. “Phineas, there are about a hundred and four things that I’d like to bust you for, but this is NOT one of them! You know what kind of trouble I’ll be in if Mom and Dad find out that THIS happened while I was in charge—you know, by default?"

Candace made just enough space between her fingers that she could only see Phineas from the shoulders up. Then she noticed the mark on his neck.

"Oh my gosh, is that a HICKEY?"

"What's a hickey?" asked Phineas. He looked at Isabella. "I think there was a Sarah Hickey in our grade last year."

"She means that bruise I kind of accidentally gave you on your neck," Isabella explained.

"Okay, okay," Candace said, clearly fighting off panic. "I can put makeup on it—it'll be fine—Mom will never know. Now BOTH of you, hurry up and put your clothes on before Mom gets ho-” She stopped and sniffed the air. “Is that vanilla?”

Candace dropped the hand that was covering her eyes, and all of the tension in her face seemed to melt away.

“You know what?” she said. “You kids have fun. I’m going to call Jeremy and see if he wants to come over and do that with me.” She glanced at her cell phone. “What, no bars all of a sudden? I hate when this happens." She looked pensive for a moment, then said, "I wonder if reception is better on the roof?” She went back upstairs, leaving Phineas and Isabella alone.

Phineas said, “I suppose we SHOULD get dressed. I mean, I’m not quite sure how Mom would take this.”

They started pulling their clothes back on.

"Now that you mention it," said Isabella, "we probably shouldn't tell anybody."

"Is it okay if I tell Ferb?" Phineas asked. "It would be weird for me to have the best summer day ever and for Ferb to not even know about it."

"I guess that would be okay. I mean, who's HE going to tell?" Isabella said. "Anyway, I should really go home and shower. This sex thing leaves you kind of sticky.”

Phineas nodded. “But can we do it again sometime? Maybe soon?”

“Definitely soon.” Isabella finished tying her shoe, then leaned over and put her hand on Phineas’ face. “I love you, Phineas.”

“I love you too, Isabella. Thanks for helping me figure that out.”

“You’re very, very welcome.” Isabella kissed Phineas once more, softly. “Best summer day ever, huh?”

“Absolutely,” Phineas answered.

Isabella giggled, then practically flitted out the front door.

Phineas turned the TV back on. The webcam was still connected, and Phineas could see Ferb sitting up in bed, reading.

“Hey, buddy, feeling better?”

Ferb was about to answer when Phineas heard a shriek of surprise from somewhere upstairs, followed by the sight of Candace falling past the bedroom window behind Ferb’s head. Then there was a strange sort of soft thud, like a sack of flour landing on a half-inflated air mattress.

“Whoa, Ferb, is Candace okay?”

Ferb went to the window, looked out, then turned back to the camera. “Candace is fine,” he said, “but I’m afraid the Duke of Wellington has met his OWN Waterloo.”

“Phineas and Ferb!” came an angry shriek from the back yard. "You guys are SO busted!"

"And...we're back," said Phineas.
