I thought about doing some work but decided against it. It was late, and I knew I’d need some sleep. I stripped down and climbed into bed. No surprise, I had another very sexually charged dream. I saw both girls naked, licking each other’s wet pussies in a sixty-nine position while I jerked off and came on their faces.
I woke up with a throbbing erection. Once I was fully conscious, and without thinking much about it, I started jacking off, replaying those images in my head. Thinking about Karina and Carly both naked, their full breasts exposed, nipples hard, tongues lapping at the wet slit in front of them. I shot several blasts of cum straight up, landing on my belly. I exhaled loudly. That fantasy was never going to get old.
I finished myself off and gingerly rolled out of bed, trying not to create any more of a mess than I already had. I staggered to the bathroom and paused. Would the girls be awake? Would someone be in the bathroom at this relatively early hour? Some little voice in my head told me to just walk in, half hoping I wouldn’t be alone. I turned the knob and eased the door open.
The lights were out, and no one was inside. I flipped the light on and went to clean myself up. I stopped and thought for a moment. I decided to go ahead and shower, rather than just clean myself up, and then go get some breakfast. I opened the glass door and turned the water on when the door on the other side swung open. Carly strode in, wearing nothing but some small, baby blue panties and rubbing her eyes. Her nipples were nice and hard this time.
Our gazes locked in on each other as she closed the door behind her. We both froze. Neither of us made a move to cover up. I doubt I could have moved a muscle at that point if I wanted to. We remained motionless for the longest four or five seconds of my life.
“Dammit Trevor,” she broke the trance first. “Why are you awake this early?”
“I have work to do. What are you doing awake?” I couldn’t help but stare right at her tits as I spoke.
“I need to pee,” she said. She stepped over to the toilet, her bountiful boobs jiggling with every motion. I smiled and closed the shower door behind me. Damn, my sister had really great tits. I could feel my dick twitching, even though I had just cum not that long ago. I heard the toilet flush as I washed myself. As I rinsed off, I noticed I hadn’t heard Carly for a few minutes. Was she still there? Had she left? I turned the water off and stood there for a moment. As the steam started to dissipate, I could tell she was standing by the sink, watching me. I opened the glass door and stood there, dripping wet in front of her.
“You done?” she asked.
“Well, yeah.” I thought it was kind of obvious. “You going to just stand there and watch?”
“You did say we could see each other naked in the bathroom.” she stated.
“That’s not what I meant,” I argued. “I was just reacting to what you had said. Plus, you never really answered.”
“I’m thinking about it.” She looked directly at my cock and pointed.
Instinctively, I looked down, and saw I had a full erection going on. “Can’t help that. You have nice boobs, remember?”
“I remember. I just never got a really good look at it yesterday. And you weren’t fully naked the second time.”
“You aren’t naked either,” I shot back.
Silently, my sister pulled her panties down, her eyes never leaving my dick. She stepped out of them and ran her hand up her pussy lips quickly.
“Wow.” I was speechless. My sister was gorgeous naked. I felt my dick twitch.
“Thanks,” she said. “So, it sticks straight out when it gets hard? I thought most guys’ boners pointed more up?”
“I guess. I’ve never studied other dicks all that much,” I confessed.
She squeezed her tit almost absent mindedly, all the while just gazing at my cock. It throbbed when she did that. She grinned at me, then turned around and bent over. I stared at her nice round ass as she pulled her panties back up.
“That’s enough for today,” she said with a wink. “Have fun in there.”
I nodded, eyes never leaving her body, “You too.”
“Don’t worry, we will.” I watched her ass sway as she headed to her door. She gave me a look over her shoulder and caught me with my hand on my dick. I yanked it away instinctively. “See you tomorrow morning.” She winked at me, then disappeared behind the door.
I was rock hard. With no hesitation, I started jacking myself off again. I put a hand on the counter to brace myself, and I pumped my cock hard and fast until I was shooting bursts of cum into the sink. I caught my breath and cleaned up.
I got dressed and grabbed my headphones. Since I hadn’t done as much work yesterday as I should have, I needed to put in a productive day today. I dialed up a playlist and sat at the computer. I stared at the screen as the music started. My sister was obviously turned on. I just knew she and Karina would be touching and kissing each other right down the hall. Was I misinterpreting this? And did she really want to see me naked again tomorrow morning? I mean, I couldn’t deny it made me horny seeing her naked, frozen in place, just staring at my hard dick like that.
I shook my head and turned up the music. I had to get a grip. I had to get some work done. I took a long, deep breath, and then got to work. For hours on end, I didn’t move from my chair. It was almost therapeutic. I had managed to push all those thoughts of Carly and Karina from my head. I was ‘In the Zone’ so to speak. I didn’t hear the knocking on my door. I didn’t see Karina walk in, wearing a thin white t-shirt with no bra, her tiny nipples partially visible through the cotton. She got within a few feet of me before I looked up, jarred back to the present by the movement in front of me. I couldn’t help myself. I stared right at her tits as she spoke.
“Your folks will be back late tonight. They stopped somewhere for Vivian to shop.”
“OK,” I mumbled.
“Are you alright? You’ve been in here all day.” She sounded concerned.
“I … I’m fine.” I managed to look up to see her smiling face. My God, Karina has the prettiest smile.
“Ok. I was thinking you might be avoiding your sister and I,” she said, giving me a look.
“I’m not, I promise. I’m just busy here,” I gestured at the screen. “Deadline is coming up on this one.”
“There’s some lasagna left over from lunch if you’re hungry.” I caught myself staring at her boobs again as she spoke.
“It’s past lunchtime?” I was surprised.
“It’s past dinner time. You’ve been cooped up in here all day,” she stated.
“Lost track of time.” My stomach was suddenly empty. “I’ll come get something to eat here in a bit.”
“Alright. We’re watching a movie if you want to join us.” She smiled sweetly at me. God she was gorgeous.
“Maybe, sure. Thanks.” I stood and stretched.
Out of habit, I stared at Karina’s ass as she walked out the door. Damn she was so hot. I had been sitting in one position for hours on end today. I hadn’t eaten anything or drank anything or even taken a piss. Suddenly, I needed to. Badly. I looked at the bathroom door. Even though I had been doing it for years, it suddenly felt weird knocking on it before I went in. Did I think someone would be in here? I think I secretly hoped, although I was sure the girls were in the living room. I whipped my dick out of my pants and pointed it at the toilet bowl. Then again, I was sure no one would be inside here this morning, or yesterday, so what did I know? I finished peeing and flushed. I hesitated for a second. Was I waiting for someone to walk in? Did I want Carly or Karina to catch me with my dick out of my pants? I struggled with that thought. I mean, as sexually charged as the last day or so had been, she was still my sister and her best friend. They were certainly off limits.
