Caitlin's POV
I was at school walking down the hall when Powder came to me with a huge grin on her face. "Caitlin, I need to tell you something!" I came down to her level, and she whispered into my ear. "It's Vi's birthday tomorrow." She beemed. "Omg, yes! Thank you for telling me, Powder." Powder smiled and said.
"Don't tell Vi I told you she doesn't enjoy her birthdays but now we are here. I think we could do a really cool party!!" I nodded and said. "Yeah, we can have a pool party at my house. I'll get it all set up, and you can keep Vi busy until I phone Vander, and you can bring her." Powder nodded, and we headed off to our separate classes.

Still Caitlin's POV
(the next day)
I was getting all the decorations ready for Vi's birthday by my pool when my mother came out. "Caitlin, what is all of this?" I stood straight and answered. "It's Vi's birthday, and she's never had one like we do up here, and she deserves it." My mother sighed and turned away. "Fine, your father and I are going out." I smiled and watched her walk away.
I put some streamers up on the fairy light pools, and I put ballons everywhere, and then I put a Happy Birthday banner up. I then ordered a caterer and then called Vander.
"Hey, Vander. Yep, I'm ready. Let Powder know." I ended the call and went upstairs to put on my outfit. I bought a swimsuit for today.
It looks like this. (I don't own the photo)

I then invited my friend Sky over for the party. She came in black swimming shorts and a flowery swimming bra. I should Sky my outfit, the swimsuit, and a thin white cardigan, and she freaked. "Caitlin? Why are you wearing a sexy swimsuit?" She asked, which made me laugh. "You think it's sexy?" She nodded, and I looked in the mirror.
"Cait, you look amazing, but there are no boys coming. Why would you.... oh. I see." I turned to look at Sky, who just smiled. "I'm shocked, I'm a terrible friend, I should have worked it out sooner." I was really confused now. "What do you mean, Sky?" Sky smirked and put her red cardigan on. "You like girls, well at least you like Vi."
I was taken aback by what Sky said. "What? Well, she is funny, smart, and beautiful, and I feel a connection with her. But I've never liked a girl before." I said, trying to get Vi out of my head and try to think of the girls from school in that way. "Maybe you're Demisexual?" Sky smirked. I looked at her confused, so she elaborated.
"Demisexual is when you feel attraction to someone after getting to know them, and that's why you've never had a crush or been attracted to someone because you never really let anyone get close. Not even me." I nodded and looked at a picture of Vi I had on my pin board. "This is going to get complicated, isn't it?" I asked my friend. "Maybe, but if she likes you back, then you two will be an amazing couple." I smiled and hugged Sky before we rushed downstairs to get ready to suprise Vi.

Vi's POV
Powder blind folded me a few blocks away from where she was taking me and then dragged me to some steps and into a building with a polished floor. We walked across it, and Powder told me. "Take it off."
" Suprise!" I heard, and when I took the scarf off, I saw Cait, her friend Sky and Powder all in swimsuits and in front of a big pool. There were balloons everywhere and streamers and a banner saying happy birthday. "Guy! This is amazing. Thankyou." I hugged Powder and then Caitlin as I got a good look at her suit. Wow, she is beautiful. I then hugged Sky and Powder and gave me my swimsuit. I left to get changed in a bathroom. My suit was a pair of red shorts and a black wrap type top.
When I came back, Powder was swimming in the pool with a unicorn foat, and Sky was putting her swim cap on. I went over to the bar where Caitlin was ready with a glass to hand to me. "Don't worry, I didn't put any alcohol in it. It's just juice." She said, which made me smile. "Thanks, Cupcake." Did she blush a little? I think she blushed at Cupcake. I tried not to think about it and clicked glasses with Caitlin before we both took a sip and moved to sit by the shallow end of the pool.
Powder had a water pistol and started shooting us from her float. "Got ya!" She laughed as Caitlin went behind me to hide. I laughed and gave her my drink before driving into the pool and swimming over to Powder. We then played king of the castle with the float, but neither of us could stay on longer for more than a minute before the other would pull us under. Sky and Caitlin were swimming too, but they were more relaxing on their floats on the other side of the pool.
Soon, a woman in a white outfit came out and said to Caitlin. "The food is ready, miss." Caitlin nodded and got us all out of the pool. I helped Powder dry off before asking. "Want to get changed? You can always put the suit back on, but you'll have to wait a little after you eat." Powder nodded and went to the bathroom with her clothes. Caitlin came up behind me, wrapped in her towel, and said.
"You know it's hot enough that she could sit out here and dry off, right?" I nodded and grabbed my towel. "Yeah, but she won't want to get back in. She always falls asleep after a big meal, so I'd rather her be dressed and out of the sun." I then dried my hair and my body before realising that Caitlin was watching. "Like what you see?" Cait blushed again! And then rushed past me and towards the kitchen.
First we did presents, Sky got me a jacket with my name embroidered on the back. "Wow, Sky, thanks, man!" I hugged her and then opened Powder's present. It was a new pair of wraps for when I use my punching bag." I kissed my sister's head. "You know me so well, sis." I said before taking Caitlin's present. It was a book that I borrowed from the library but I didn't know you had to give it back. "This is mine?" I asked worried she would take away my favourite book again. "Yes Vi this is your copy. You can keep it forever." I smiled and hugged Cait. "You are the best.
We all then started to eat, and each of us had grabbed quiet a bit of food for our first helpings, so I was the only one who went for seconds and thirds. Powder, like I said, she would fall asleep, so Caitlin offered her room. I smiled and thanked her before carrying my little sister up to Caitlin's room and placing her on the bed.
I then went back downstairs where I heard Sky and Caitlin talking, and I think I heard my name. "Okay. I get it. I'm a looker, don't hind it anymore ladies, cus I know you want me." I said as I flexed my arm and soon to be abs if I kept working out. Both girls laughed, which made me laugh too.
"Well, it's time for me to go home, I will see you later Caitlin, happy birthday Vi." I thanked Sky as Caitlin showed her to the door, I got back in the pool and lay down on the float. This was a great birthday. I relaxed under the sun and closed my eyes, and not after too long, I heard Cait swimming over.
"Hey, Cupcake." I smiled as I turned over, Caitlin smiled back and rested her arms on the float. "You are really good to Powder, you know that?" She said, I laughed so Cait got on the float properly. "I mean it Vi! If I had a little sibling, I wouldn't be like a mother to her." I frowned and said. "Our mum and dad died when I was 12 and Powder was 9, Vander was our carer he took us in and is an amazing dad but, I'm the only one who can protect Powder from this world. So yeah, I am like her mum."
Caitlin looked saddened by what I said. "I'm sorry Vi I shouldn't have brought it up." She hugged me, so I hugged her back. "Hey, it's okay. It's good to talk about my past. That's what Vander says." Cait pulled away. And we both led down on the float. "What about you? Do you have any childhood trauma?" I asked playfully, but Caitlin looked away from me. "No. And I hate myself that I had it so good." I touched her cheek and smiled. "Stop talking Cupcake you'll upset yourself."
Caitlin held her hand over the one I had on her cheek and smiled, then looked me in the eyes. "I like you Vi..." Before she said anything else, I kissed her.

And all this time, they didn't know Powder was watching from the window in Caitlin's bedroom. She could she was being replaced.
