A/N: This has been something I wrote on since I got back into the Phineas and Ferb fandom and also into the Phinerb fandom. Be aware that this is PxF. If you don't like it, I ask you not to read and comment it. Thank you!

It was the last day in High School for us, a very special day for most of our co-students and we celebrated this day with a little party in the gym hall. Everyone was joyful and filled with pride over their final results on their school reports. Everyone was enjoying some cold drinks and snacks in there and the decoration of the hall was amazing! Everything was in blue and silver, our football team colors and people were doing small talk or danced to the music that was on and very loudly – almost a little too loud for my taste.

I was going through the crowd of people, talking with one person here, with one person there. But there was someone missing – my brother!

It was unusual for him to miss this ceremony since he was looking forward to it the entire month. At home and no matter in what situation, he was talking about it: By lunch, at night when I was trying to sleep, even when I was underneath the shower he burst into the bathroom and kept on telling me about it. I was happy when the big day finally arrived and now he is not even here?

I got worried. I know something must have been wrong. I told Baljeet, whom I was having a conversation with at the moment, that I would disappear on the toilet for a moment and made my way to find the red-head.

Phineas was known as Mr. Physics the entire school time over. He attempted an extra physics club after school and simply loved that subject. Not many girls were impressed by that, but it shouldn't bother me. In fact, there was actually a guy that has thrown an eye on him. This guy was merely to shy to tell him and feared the consequences of trying to be with him. This guy was, as stupid as it sounds, me! His own stepbrother...

I don't exactly know how it happened. Phineas grew to a very handsome, young man over high school. That is when I got my crush on him. He was very tall, it seemed like his eyes became even more blue and his style of clothes was always in a comfortable sporty way. His long neck seemed to invite me to place plenty of kisses onto it and his thin arms just wanted to get caressed. It was a pain for me to live in the same room with someone so beautiful and cute...

It didn't really feel like we would be stepbrothers. I rather got the impression that we were best friends, almost lovers at heart. But I was afraid that only I would be thinking so.

However, I have made my way through the crowd without any success finding Phineas. In my head I went up and down the school building, wondering where my brother could be. Finally, I remembered that his favorite place has always been the physics room. That is where I wanted to try my luck. I went up the stairs to the first floor and knocked the door that led to the physics room, entering it carefully. What I saw inside was quite shocking me: Phineas was sitting in the next corner, holding a bit too close onto a piece of paper and was crying. His eyes told me he was scared, seriously scared. I closed the door behind me and went up to him, going down to my knees as I finally reached him. "Phineas...", I whispered, not wanting to make him jump. It doesn't seem like he saw me entering the room.

With his teary eyes, Phineas looked up to me. He opened his mouth to say something, but no words came out. I was usually the one not saying too much, but this time I had to take the lead.

"Phineas, what is wrong? What is that?", I asked and pointed at the piece of paper in his hand.

Phineas handed it to me, sobbing and crying even more. He buried his face into his hands, being embarrassed about what I was going to read.
It was Phineas' school report I was looking at. It was all looking good, actually, except for one grade that was in the section of P.E. Lessons. A huge "F" was filling the place where everywhere else was written an "A" or "B".

"I won't make it...", Phineas whispered as he watched me looking over his report, "It was simply too much..."

"What did you do to get such a bad grade there?", I asked him and laid the paper beside me to look him directly into his eyes.

"I... I am merely not a man of action", Phineas exclaimed and went on crying, "Not all of us can simply be like you, Ferb!"

Phineas was part of right. Thanks to my skills in sports and activities, I made it to become the Quarterback of our football team. We have never lost a game since all the players in our team were fantastic. Everyone kept saying it would be thanks to me, but I find it very unfair to say so. One person can't make a team, after all.

I looked down to my brother and stroked his cheeks slightly. "Phineas, that is just one bad grade...", I answered.

"I have to repeat the year...", Phineas says, "I know that for sure. I am simply not the right boy for this. But everyone expects me to be that just because you are my brother. We are stepbrothers, that is something very difficult... I wish I would be as good in sports as you, so that..."

I interrupted his hysterical speech by simply pressing my lips on his', leaving Phineas in the moment of shock and surprise. I could feel that he was trying to understand what was going on, but I couldn't notice any try to pull himself away from me.
What happened then was a real surprise for me. Phineas closed his eyes, being totally lost in the moment. His lips loosened a bit which gave me enough room to enter my tongue into his mouth. It was another shocking moment for him as a slight "Mmhh..." escaped his lips and his eyebrows narrowed. But soon he relaxed and wrapped his arms around me. Our tongues were wrestling playfully with each other and some saliva dripped down on Phineas' chin...

We broke the kiss for air and didn't even dare to look at each other. Phineas face was blushing deeply and he rubbed the back of his head, trying to find the right words to say after that surprising kiss.

I was looking down to the ground as well. How could I? How could I let myself and my emotions go so easily? What crossed my mind to do something like that? I was pretty sure Phineas didn't want to speak any more words to me. I was close to get up and leave the room as I suddenly heard Phineas' voice speaking to me.

"Since when...?", he asked and blushed even more.

I looked at him with surprise. "Since when... what?", I asked back.

"Since when did you wanted to do that?"

"Since beginning of High School...", I answered.

"Ah...", was the only thing Phineas said, feeling even more embarrassed about my answer given. He collected together all his courage to look up to me right in my eyes. His eyes were shaking and so was his voice as he said, "I.. I think I love you, Ferb..."

These words made me lose all of my self-control. I picked Phineas up, carrying him over to one of the tables that were standing in the room and made him sit on there. I was taller than him, so it was easy to bend over him and place passionate kisses onto his lips. I unbuttoned his shirt immediately and threw it off, leaving him with only the tie covering a small space from his bare chest. I couldn't help, but caress his shoulders and over his chest.

A few moanings flew out of Phineas' lips, but soon he just hold back my arms and lips. "N... No... F... Ferb...", he stuttered, "Not that... not here... please..."

I looked at his highly red head and smiled slightly, kissing him a few more times. "Of course...", I said and picked up his shirt again, "we will do that once we're home..."

Phineas blushed even more, but soon just wrapped his arms around me and nodded. "Yes...", he replied, "Let's leave and go home..."

And with that words, we left the school building to go, hand-in-hand, home...
