I felt a light brush against my arm, startling me awake again, and I lurched myself upright in bed. "You've got to stop doing that Cai-" I started to say, rubbing my eyes open and squinting.
"Sorry, Andy! I didn't mean to scare you!"
It was my stepsister Casey, not Caitlyn, sitting on the edge of my bed this time. I felt a huge relief Casey had interrupted me just then, because I thought it was Caitlyn again.
"It's ok," I told her. I realized the spot she touched on my arm was really sensitive, and remembered it's where I landed when Caitlyn and I fell out of the shower last night. I pulled my arm out from under the blankets to rub it.
"What happened to your arm???" Casey exclaimed.
Looking down, I realized there was a big bruise right on my elbow. "Uh," I thought quickly, "I just fell walking up the stairs last night. No big deal I just wasn't paying attention. I was texting a friend of mine and missed a step," I told her.
Casey smiled. "Do you want me to get you some ice? Or I could rub it for you?" She asked me. "I'll be really gentle!" she ensured.
"Oh, gosh Casey," I started, and took a long exhale. "It's alright." I looked up to her and smiled back. It was morning, and the sun's light brightened up my room through closed blinds, the light setting a halo behind Casey's entire body. Casey smiled back at me lovingly, placing her hand lightly on my knee. The room being so bright from just waking up along with Casey's warm aura made me feel like I was still in a dream.
"You know," Casey started to say. "Caitlyn fell out of the shower last night. She's got this huge bruise on her hip, too. I swear you two were meant for each other or something," She laughed.
"Is everything else alright, Andy?" She asked a moment later, a little concerned, her fingers gliding along my knee. "About last night, I mean," she added. My body was covered with blankets, but Casey's touch along my knee made me remember I was still completely naked from yesterday. I never put clothes back on after skinny dipping with Caitlyn and Taylor. "You went to bed pretty early last night, I was worried you might have had too much to drink. I was hoping you weren't sick."
Casey reached for a glass on my nightstand, twisting her body to the side and bending over a bit to reach it. Casey was still in her pajamas and light reflected through her now nearly see-through white t-shirt while she was bent over, giving me a profile view of her breasts. It wasn't perfect, but it was enough to see she wasn't wearing a bra and also enough to know exactly what they looked like underneath her shirt. My mind immediately went places it shouldn't. Thoughts of a topless Casey filled my head, her amazing c-cup breasts exposed to me, made to look even larger compared to her flat, tight stomach. Casey grabbed the glass and twisted back towards me, the images fading in an instant, just as quickly as they had come. My heart fluttered and my penis began to eagerly twitch, swelling slightly.
"I brought you a glass of water, in case you were a little hung over this morning," Casey said handing me the glass.
"Thanks!" I replied, grabbing the glass and taking a few sips. "I am a little dehydrated from yesterday, actually," I admitted, not telling her it wasn't really from drinking too much alcohol. "That really hit the spot!" I said, gulping down the rest.
There was a short pause. "That was really thoughtful of you," I told her.
"Oh, it's nothing, really. I mean, what's a sister for!" She said gleefully. "It's so cool saying something like that after going my whole life without a brother, you know?" Casey asked, her hand warmly sliding over my knee again, this time making its way farther up my thigh to the point I was a little worried she might reach high enough to feel my enlarged cock. "I mean, you're not my real brother, but it's just cool having someone you can care about and trust, you know?" Casey closed her eyes and tilted her head up, giving me the biggest, dorkiest smile she could manage, then looked back down to me, and paused.
"Shut up, sis," I chuckled after a moment nudging Casey's shoulder, and Casey back fell into me with laughter, putting her head down into my chest, pushing me down into bed. With this, my hard cock sprang upward pressing against Casey's body. Just the feeling of her stomach against my penis made my thoughts race again. Casey stopped laughing for just a second, and I was certain she noticed my hard penis, but she pressed herself up off of me and continued to giggle, her breasts bouncing with each subtle vibration of her body, pronounced by the fact she wasn't wearing a bra.
"That wasn't even funny," Casey said continuing to smile. "Why are we even laughing?"
"I'm not even sure," I admitted.
Casey wiped a tear forming in her eye, and composed herself. We looked at each other for another moment or two. I desperately wanted to ask her about last night, whether or not it was her watching Caitlyn, Taylor and I skinny dipping last night. If she saw us playing with each other's naked bodies in the lake. I wanted to know if she enjoyed watching us. If it turned her on, got her wet. I could feel my erection getting harder.
"Hey Andy?" Casey said. I realized I was looking at her chest again, and looked up. "Lost in thought, huh?" She questioned.
"Yeah, Sorry!" I said, looking down hoping she didn't notice I was staring at her while also bending my knees up to make my erection less noticeable under the blankets. I could feel my cheeks flush with red.
"No worries, I daydream all the time!" Casey said reassuringly. "Anyway, why'd I come up here again? Oh yeah! Well, I'm glad you're not hung over or anything. And I wanted to tell you I missed hanging out with you last night. Let's make up for it tonight this time, alright?"
"Yeah, of course," I told her. "I really want to spend more time with you too!"
"It's settled, then," Casey said. "Come down for breakfast, your dad made everyone blueberry and chocolate chip pancakes! Try not to use up all the world's ketchup this time."
I looked dully at Casey. "Really?" I asked. "Good one," I said sarcastically. Casey stuck her tongue out at me, smiled, and got up to leave the room. I watched as she left. Even under pajama pants you could see her amazing figure underneath.
I sighed with relief once she closed the door. Why do my thoughts get so sexual when she's around? I've never had feelings about her like this before, but now that they started, I felt they were completely out of my control.
I took another moment to compose myself, got up and put some clothes on, and went downstairs for breakfast. The smell hit me before I even entered the dining room. Hot, fluffy stacks of pancakes awaited me. I sat at the table with all the other girls, and said good morning to everyone. Jess and Caitlyn both looked up to smile at me and said hello back, but Taylor just kept her head down and continued eating. She was obviously back to her shy, bashful self. I hoped she didn't feel embarrassed about last night at all.
I grabbed my own stack of pancakes and opened the syrup, pouring a bountiful amount over them. "Careful with that," Casey said to me.
