Thanks for the reviews! Ok, now here's where it gets M. This is my first "lemon" so it's probably really bad. Also, I tried to keep it clean, if that makes sense. It's like, non-overly-descriptive, if that makes sense. Barely a lemon. More like lemon flavored toothpaste: clean but lemony. Of course, citric acid is bad for teeth. Whatever... please review, just to tell me how this was.

I had been pacing back and forth for so long I was beginning to think the floor was going to give out. And I just couldn't stop. There had really been no point in asking him to come over after dinner because I had barely eaten anything. The only thing I could think of was… is he actually coming over?

I clutched my mug tighter. Hot chocolate would've put me to sleep and coffee would've had me up till morning, so I was drinking tea. Of course, I had already had about four mugs, so I might be up till dawn anyway. At least it would keep me from feeling hungry.

I put my mug down on a table. I noticed I was basically shaking. Oh my god, oh my god… why did I even ask him? It was his fault; he suggested himself. It was the girls' fault; they came up with the idea. It was Phineas' fault; he drove me to this. Ohhh… Isabella, get a hold of yourself!

I went into the bathroom and splashed myself in the face with some cold water. After I wiped it with a towel, I stood back and looked at myself in the mirror. Hmm… I was wearing a tight three-quarter sleeve gray shirt and fluffy pink pajama pants with puppies on them, with my hair in a loose ponytail. My typical sleep apparel. But suddenly it seemed really stupid. Puppies? Really? I should've tried harder than this. I should be wearing some of that fancy lingerie from magazines. I peeked under my shirt… a boring skin-colored bra. And I'm pretty sure my underwear is navy blue. Great, so I'm mismatched. I need to go change!

Oh my god, oh my god… wait a minute! I mentally slapped myself. The whole point of this was that Ferb was just a friend and he wasn't going to judge me. And nobody was forcing me to do this. I made the decision myself, and he agreed. I wasn't supposed to be stressing tonight. Tonight, I was supposed to have fun.

Somebody knocked at the door and I almost leapt ten feet in the air. It was Ferb! It had to be!

I quickly walked over to the door and looked through the peephole. Yup, it was Ferb all right. He was just waiting in the hall nonchalantly. He was just wearing some gray sweatpants and one of those white undershirt-like T-shirts. Okay, Ferb was dressed just like me. If I get so nervous with just Ferb, how am I ever going to get this far with Phineas? Come on, Izzy, you can do this! I took a deep breath and opened the door.

"Hey." I said. Ferb gave me half a smile and a faint wave, but he didn't seem to want to make eye contact. "You… you actually came." I said nervously.

He lifted his head. "Maybe I should just go…"

"NO!" I said loudly, cutting him off. He stared at me in surprise. And I was blushing again. Man, I must sound so desperate. "Come on in."

He followed me into my apartment, as I shut the door behind him. He had been in my apartment before, but he was still looking around as if he hadn't. "Umm, make yourself at home." I said.

I plopped down on the couch and he silently sat down next to me. Oh, why was he so quiet? "We could just watch TV for a little while." I suggested.

He stared at me with those all-knowing Ferb eyes. "Isabella…"

Oh no, I knew that tone! He was going to say something like "this is wrong" or "you're not ready" or "wait for Phineas, he'll come around". No, I was done with Ferb's little lectures! We had both agreed to this, and we were going to follow through!

"Come on!" I stood up and grabbed his hand. "Bedroom time!" I tugged him along to my room, flung the door open, and kind of pushed him on the bed. I slammed the door closed, pulled out my ponytail holder, and wildly shook my hair loose. I hope my craziness was turning him on, because acting dramatic was helping me get through this.

I sat down next to him. "So…" I mumbled awkwardly. When we went through ground rules, we never mentioned what we'd actually be doing. "Maybe we should… kiss?" I suggested. I had never kissed Ferb. I had never even thought about kissing Ferb. But if I was going to sleep with him, I'm thinking kissing would be involved.

Ferb smiled that little half-smile again, gently brushed my runaway hair off my face, and began moving towards me. Oh my god.

His lips met mine, and he kissed me very softly. And I gently pressed back. Aww, Ferb! He was so sweet. This was such a sweet little kiss, the kind he would probably give his girlfriend all the time. Vanessa didn't know what she was missing. But I wasn't his girlfriend, I was his FWB. So I started kissing back a little harder, more aggressively. And he did too. And suddenly I was frenching Ferb with him on top of me. And I was running out of air.

I broke away, gasping a little. Ok, so maybe I was wrong about Ferb being all sugar and no spice. That didn't mean I didn't like spice either. He was staring at me. I pulled him back on me and kept kissing him.

"Ok… now… what… Ferb?" I asked, getting only one word out between each kiss. He didn't say anything. He just moved to kiss my cheek, and then move on to my neck. I moaned. "Okay, neck next." He was kissing it. Somehow, he managed to find all the sensitive spots and lightly nibble at them.

"Wait, Ferb." I said, sitting up. He sat up too. "No hickeys." I warned. He nodded. I suddenly felt very hot, and that reminded me that we were both still in our pajamas. Oh boy, I think I knew what the next step was.

"I think we, uh, need to start," I gestured to my body. I wasn't sure what to say. "Undressing."

Ferb nodded. Eeek! What was I supposed to do? I noticed he was taking off his shirt and pants by himself, so I guess I should do the same. I peeled my clothes off my body. Yup, navy blue panties. I probably looked really stupid.

I peeked back over at Ferb. He was sitting there, in his boxers, waiting for me. I gulped and laid down on the bed. "Okay, Ferb." I said. "I'm ready."

He crawled over to me, and was back on top of me, looking down. Awkwardness. "Umm," I stammered. "You were hiding a hot body under there all these years, Ferb." It was true. He was super muscular and, dare I say it, sexy. I guess Phineas was right when he said Ferb's been working out. "How do I look?" I joked.

"You're beautiful." He said. He didn't say it in a loving way, or a flirty way, or even in a friendly way. He said it as if it were a fact. As if everyone in the world knew it.

"Thank you." I said awkwardly. "What… what's next?" As if I didn't know. There were just a few flimsy bits of fabric separating me from Ferb. And I was freaking out. "This… this is fun and all, right Ferb?" I stammered.

"Isabella…"

"Don't give me that stupid knowing tone, Fletcher!" I shouted angrily. "We agreed we were going to fuck, so let's just do it already!" The second it came out of my mouth, I realized how loud it was. "You… you don't think anyone heard that, do you?" I whispered.

Ferb's eyes were twinkling and the corners of his cheeks were about to turn. "Oh my god!" I said, as I sat up. "You're laughing at me, aren't you?" I was trying to sound angry, but I was smiling too.

He put both hands on my shoulders. "Isabella, RELAX. This is supposed to be at least somewhat enjoyable."

I giggled. "Don't get me wrong, I'm definitely enjoying it. I'm just a little nervous."

"Don't be." He said.

"Why weren't you talking the whole time, you jerk?" I asked playfully. "You liked listening to me stammer like a fool?"

He shrugged but he was smiling. I laughed, but then bit at my lip. Because for the first time all night, Ferb was REALLY turning me on. Just by, well, being Ferb.

"Ferb, if you still want to… you know." I said. "I think I'm ready. But I'm still really nervous."

"Just relax. You can close your eyes if you want to." He replied.

"Ok." I began gently kissing him again, and his arms snaked around my back, unhooking my bra. Oh my god, oh my god, wait Isabella, just relax.

I laid my head on the pillow with Ferb hovering over me. He only gently skimmed my chest with his hands, making me moan. His hands were sliding lower.

"I'm closing my eyes now!" I shrieked.

I was naked. He had slid my panties right off of me. Oh my god, oh my god, oh my god.

I felt Ferb kiss my cheek. "Are you ready?" He whispered. I nodded and he kissed it again.

And then… and then… well, I'm not even sure what was happening. I was screaming and moaning all sorts of things that would normally never EVER come out of my mouth. Swears, and commands, but mostly Ferb's name, over and over. Ferb was making some little grunting noises and my stupid old bed was squeaking so loudly I swear we were going to break it. My eyes were squeezed tight the whole time. But when it hit me, I swear I was seeing stars. My brain had just popped and I was dead. And it felt amazing.

Only when Ferb rolled off of me did I open my eyes. I stared at the ceiling and listened to the quiet pants from both of us. I think I was familiar enough with Ferb's silent communication that I could tell we were both thinking the same thing.

Oh my god!

There we go, that wasn't so bad, was it? What happens now that Ferb and Isabella are officially FWBs? Well, more awkwardness for sure...
