Wow. My dick was already hardening again as I cleaned myself up. I had seen her masturbating twice now and the sight was awe-inspiring. How was I ever going to get any work done with her and Carly around me?
I stayed in my room for a while. I wandered back to the living room when Mom and Dad came home. Mom had her hands full of shopping bags and Dad sent me to get all the luggage from the car. As I came back into the house, Karina was standing there talking to Mom. Her eyes caught mine and widened questioningly. I gave her a quick nod and went about my business taking suitcases to my parent’s room
Karina talked with my parents for a while before they went to bed. They both had to work in the morning, whereas school didn’t start for us for another couple of days.
I went back to my room. I was getting close to finishing the project I was on, and I needed to push through. I worked for a few more hours. Finally, just after midnight, I was done. I hit submit and sat back in my desk chair, very satisfied.
I heard the front door open. Carly was home from her date. I thought about going to greet her but then I thought more about it. Karina needed to talk to her, I’d only get in the way. Although …
I remembered the way Karina came home the other night and went right into Carly’s lap, talking about how horny she was and how wet her pussy was. Did Carly come home just now in the same mood? And then my mind flashed back to seeing Carly in the bathroom this morning, peeling her panties down and showing me her smooth pussy lips. I remembered how she ran her fingers over them idly. Dammit, I was hard again.
I had to stop this. I stood and stretched, then my bladder spoke up and I went over and knocked on the bathroom door. I heard the toilet flush and then Carly called out, “Come in.”
I opened the door and walked in.
“Hey brother. You’re up late again.” She stood there at the sink in the exact same outfit Karina had worn the night before. Tight black skirt, yellow tube top, which featured her breasts as prominently as it had Karina’s. She looked good. Really good.
“Finished a project for work. You have a good time tonight?” I asked.
“Oh yes. We saw that new Marvel film. It was really fun.”
“That’s cool.” I said, trying not to stare at her tits.
She turned and faced me. Without warning she reached out and gave me a big hug, pressing her breasts into my chest. “Yep, you definitely like this outfit,” she giggled, feeling my dick pressing into her leg.
I pulled away. She smiled and put her hands on her hips. I lost the battle with my cock as he got fully hard and threatened to rip through my shorts.
“You do look really nice, sis,” I said as I headed over to the toilet and lifted the lid.
“Thanks.” She leaned back against the sink. I stood there for a moment, hesitating. I expected her to leave. “Don’t mind me,” she grinned. “Carry on.”
I pulled out my hard cock and held it. This was going to take some serious maneuvering to not make a mess all over the place.
“I always wondered how guys pissed with a boner,” she quipped, sensing my struggle.
“It’s not easy.” I admitted. “Usually, it’s better to wait for it to go down some.
“Ok. How long does that take?” she asked.
“Well, with you standing there staring at me, dressed like that, I don’t know if it will on its own,” I confessed.
She giggled. “So, what do you do next?”
I wasn’t sure what to do. I really needed to piss, but there was no calming down my cock. I could see Carly’s nipples through her blouse. She shifted her weight, causing her thighs to slide against each other noticeably. I was certain she was as turned on as I was.
Without really thinking, I stepped into the shower stall. I took a couple of slow, deep breaths and tried to relax. My cock, still pointing straight out, let loose a stream across the stall and splashed against the tile on the opposite wall. I heard Carly giggling. I finished, shook the final drops off and turned the shower head on for a few seconds, long enough to let the water rinse the evidence down the drain. I stepped out and stood in front of my sister with my cock still hanging out of my shorts.
“That was so cool. How often do you do that?” she exclaimed.
“Piss in the shower stall? Never really had to before tonight,” I said, truthfully.
“It went down some,” she said, staring at my now half-erect cock, still hanging out in the open.
“Yeah, sorry, that happens after I pee,” I apologized, though I wasn’t sure why.
“That’s alright,” she said, still staring at my dick. “I like watching dicks get hard.”
“Keep talking like that and I will get hard again soon,” I said, feeling it start to throb.
“Let’s see if I can help it along.” And with that, Carly pulled her top down and her luscious tits popped right out. Her nipples were visibly hard and were sticking out quite far. I caught myself licking my lips. Damn, how I wanted to suck those. I could feel my cock starting to throb harder.
“It’s moving by itself. That’s so cool,” she said, squeezing one of her breasts lightly. “I like seeing it get hard.” And then she grabbed the hem of her tight black skirt and worked it up her hips a little at a time. Slowly her slick, bald, pussy came into view.
“Mmmm.” I couldn’t keep myself from moaning. Her pussy lips glistened with a hint of moisture. She was clearly aroused.
“That’s what I wanted to see. Him all nice and hard again. I can even see it pulsing,” she cooed. I instinctively grabbed my dick and gave it a few strokes.
“Save that for later,” she said, pulling her skirt back down. As she covered her tits back up, she winked at me. “Go have fun in your room. I’m going to go and have fun in mine.” She paused. “See you in the morning.”
She disappeared behind her door. I backed out into my room. I couldn’t get that view of her pussy lips out of my mind. I dropped my shorts and jerked off again, pointing my erection at the bathroom door. She pulled her tits out for me. She showed me how wet her pussy was.
Plus, there was her statement “See you in the morning.” Does that mean she wanted to see me naked in the morning again? Or was that just a general nicety? After the events of tonight, I hoped it meant the former. I closed my eyes and saw her hard nipples in front of me and shot yet another load onto the bathroom door. I staggered backwards, collapsing on the bed. I would have to clean that up in the morning.
I woke up suddenly. It was either very, very early or very, very late. I couldn’t yet tell. Out of force of habit, I stumbled across my bedroom into the dark bathroom. I stood there in front of the mirror, waking up a bit, when Carly came in the other door, wearing some plain yellow panties and nothing else. She stopped for a moment and smiled sheepishly.
“Hey. Karina’s awake. We were going to grab a shower here in a minute and go out this morning.”
“Oh. Yeah, sure. I’ll leave you alone. I just need to piss.” I said, lifting the seat to the toilet.
“Cool. Go ahead,” she said, leaning back against the counter to watch. Her boobs jiggled with her movements. It was fascinating.
She stared at me, expectantly. I pulled my dick out of my boxers, which was not quite fully erect yet, and let loose into the bowl. I let out an involuntary sigh. I finished, flushed and turned back around, letting my dick swing freely in front of me.
“You going to go jerk off thinking about us showering?” she asked, running her hand over her nipple slowly.
“Umm… I don’t know. Maybe,” I lied. I most certainly was going to do just that.
“Cool,” she said, then pulled her panties down. She grinned wickedly at me, then started slowly rubbing her pussy right there in front of me. I watched as her hands slid up and down her slit, circling her clit a few times before sliding back down between her labia.
I stood there staring at Carly playing with her pussy right in front of me. She grinned, then we both heard noises in the room behind her. I darted back out of the bathroom and shut the door.
I sat there on my bed, staring at the door. Dammit, I was hard again. I seemed to be in a constant state of arousal these past couple mornings. I stood and put my hand in my boxers to grab my cock when there was a light knock on my bedroom door. Karina popped her head in right as I pulled my hand out of my shorts.
“Can I come in? I’m not interrupting anything am I?” she asked with a soft smile.
“No, just waking up,” I lied.
“OK. I’m sorry about yesterday, and … well, you know…” She looked worried.
“It’s fine. Not a big deal.” I tried to be reassuring.
“You’re not weirded out about it?” she asked.
“No. I mean, the last few days have been pretty weird anyway, so that just fits right in,” I said.
“I was so embarrassed.” She blushed. It was adorable.
“I could tell. I won’t make a big deal about it or tell anyone,” I assured her.
“Thanks.” She turned to leave, then stopped, and turned around to catch me staring at her panty covered ass cheeks. “Carly told me she walked in on you the other morning with your pants down.”
“I figured she’d tell you that,” I said with a shrug. “I guess something like that was bound to happen eventually.”
“She said your dick was hard,” cutting me off.
“Oh?” I said, caught off guard, “I mean … yeah, I guess it was.”
“And it was big.” She was very matter of fact about it.
“Oh.” I didn’t know how to respond.
“Maybe I can walk in on you sometime too. You know, kind of even things out a little,” she said with a gorgeous smile.
“Uhhh … sure?” I stammered.
“Cool. Well, we’re going to go take a shower now,” she said and closed the door behind her.
“Yeah. Have fun.” I called out.
I fell back on my bed. Holy shit! She pretty much just said she wanted to see me naked. Or, at least wanted to see my dick. I pondered the possibilities. Should I walk right in on them now? Drop my shorts and whip it out for her?
I laid back and started jacking off slowly as I thought about her tone. She wasn’t mad, and even sounded a little … turned on perhaps? Maybe Carly had told her about this morning as well? I was both confused and horny as hell. I increased the pace of my strokes, picturing Karina and Carly in the shower together again. They both had great tits. I could see them rubbing their breasts together under the water spray … and I was the one spraying now. Cum shooting up in the air and down on my chest, coating my hands and in my pubic hair again. I needed a shower now. I laid there, catching my breath, when I heard the water turn off. I stood up and went to knock twice on the door.
