“I’ll just grab more when I go into town to get the girls.” Dad had said, popping the tab and handing me one. I ate a little bit more, making a sandwich to go with the booze. It wasn’t as hot as it had been the day before, though it was another clear day and the sun was bright over the calm lake.
Around two-thirty, dad got a text.
“Looks like they’re done early.” He said, standing up. “You wanna come or stay here?”
“I’ll stay here.” The sun and beer had made me lazy. Besides, I could hardly talk to Liv about us fucking while in the back seat of our family ford.
I did stand up though, and followed him into the cabin. While he grabbed the keys and put on his shoes, I climbed the ladder up to the loft. I was fully planning on changing into my suit, and going back out on the deck. However, the heat up there, not quite as unbearable as it had been the night before, felt comforting. I lay face down on the bed, taking a second.
“Alright, be back with ’em in a bit!” Dad yelled, then there was the sound of the door shutting and the car starting.
I lay still for a while. The bed was really comfortable all of a sudden. Despite the tumultuous first forty eight hours, this was supposed to be a vacation, after all. I pulled myself up, but only enough to kick off my shorts and take off my shirt. On my back with hands behind my head, in just my boxers, I closed my eyes, the heat of the room keeping me down like a weighted blanket, comfortable and relaxed.
Liv will want to swim when she gets back anyways… I thought as I drifted off.
**
The faint sounds of movement and talking from below pierced my consciousness, worming its way through dreamland into my foggy brain until I realized I was gradually waking up. I was so comfortable, I let the sounds go, not struggling too hard to hold onto their meanings. After a while I fell back into a light sleep.
I stirred again at the sound of the ladder. Only two days, and already that creaking was becoming a familiar, routine noise. I kept my eyes closed, my hands still behind my head. I had begun sporting an erection in my sleep, tenting my boxers, and I could tell from the breeze it pulled the fly apart slightly.
I felt Liv enter the room. It wasn’t like she made a noise, necessarily, but I knew she was there before the bed indented under her weight. She crawled over next to me. I pretended to be asleep, though figured she could probably guess I wasn’t. I felt the bed crease where she stopped, she had come to sit by my waist. Not a moment later, I felt fingers tracing their way up my bare legs.
Liv’s small hands worked their way up, her newly pruned nails scratching lightly, just enough to feel good, running across my inner thighs, past my crotch toward my lower stomach. My dick twitched when she strayed close to it, and I heard her let out a little laugh. Deftly shifting the thin fabric to the side, Liv pulled it through the fly, grabbing my shaft and giving it a squeeze. That prompted me to crack open my eyes. I was met with the cute curled lip and matching mischievous grin.
“Mom and dad?” I asked, first things first.
“They went on another walk,” Liv replied. “I am under strict instructions not to wake you up.”
“You failed.”
“I wasn’t trying very hard.” It was the first time I’d seen my sister today. She was in that same white crop top from the night before, her toned midriff peeking out from between that and a pair of simple athletic shorts. She was sitting cross legged, her sandy blonde hair up in a ponytail. It was lighter blonde now, changing with all the sun it was getting. Her skin was a deeper color too, having time out of the sun to take on a tanned sheen, the spa treatment only accentuating her natural beauty. And she was giving me a hand job. Casually. Like it was no big deal. Liv worked my shaft with one hand, while her other hand explored my balls, almost absent-mindedly, like she was playing with a new toy.
“I missed you this morning.” I said, trying to focus, a task she was not making easy. “I wanted to talk. I was worried when you were gone.”
“Worried about what?”
“I dunno… That you’d run off. Decided what we did was gross, an abomination. And you hated me. Something along those lines.”
“You’re so dramatic.” She said smiling, and gave my cock an extra firm squeeze. “You don’t seem to have a problem with it right now.”
“Uuhh..” I groaned. “No I don’t. I didn’t, I mean. I was worried you might, that’s all. We didn’t really talk. I wasn’t sure what you felt, I guess.”
“Well… dad did give me a scare.” Liv looked thoughtful, her hands slowing, her attention elsewhere. “But I did enjoy it. And I still don’t regret it, if that’s what you’re asking me. I don’t see how anything really changed in the last twelve hours.”
“Well, for one, our blood isn’t running quite as hot,” I said.
She gave me a wicked grin. “Speak for yourself.” Liv spit in her palm then, rubbing the wetness up and down my length until her hand was moving more easily. She matched it with an increased pace, and I lost it for a second, jolts of pleasure shooting through my cock as she stroked it. “Someone seems just as excited.”
“I’m trying to be serious here…” I groaned again involuntarily. A bead of precum leaked out of my dick, Liv’s thumb rubbed it off my tip and she snickered. “You’re making things difficult…”
“You haven’t asked me to stop…” Liv teased. “But okay, here is how I see it, I guess. We’re here for the week, just us four right? You’re horny, I’m horny, we both find each other sexy as fuck, why not just have fun?”
“Because we’re siblings? Because if our parents catch us, they’ll be all hell to pay?”
“To your second point, we’ll just be careful. A lot more careful. No more forgetting clothes in the main room.”
“My bad,” I conceded.
“And to your first point, I guess my feeling is just, so what? Not like we’re trying to have babies or anything. Sex is sex. I don’t feel like we’re doing anything wrong, not really.”
“I think a lot of people would disagree with you.” I was doing my best to focus on her words. She spit again, this time directly on my dick. Watching it fall straight from her mouth onto my glistening head was so fucking hot. A trail got caught and she had to reach up with her hand and pull it down.
“Do you disagree with me?” Liv asked, after cleaning the spittle from her lips, her hand moving up and down my length.
“No. I guess I don’t.”
“Then what does it matter?” She was quiet for a second. “Besides… Last night was… I’m not sure…”
“It was really good.”
“Yeah…” Liv said, making eye contact with me again.”Like really fucking good. I was turned on all morning thinking about it. Thinking about this hard cock. My brother’s hard cock, inside of me again, sitting on it this time…” Her hands traded places, the one now on my cock went faster, the other cupping my balls. Slightly drier, the increase in friction was sudden and electric. Fuck. I realized I was going to cum. It was one of those orgasms that just sneaks up on you, intense and abrupt.
“Oh fuck…” I mumbled, erupting. Pleasure burst from my dick as I came, spurting semen all over her petite hands, and onto my boxers and stomach. Liv stroked me through it, smiling in satisfaction at her ability to get me over the edge. Once I was finished, she let go of my cock, now a less hard sticky mess, and let it droop to the side. Then she wiped her hands on my boxers, trailing cum into the fabric and across my stomach.
“Coulda warned me there.”
“I didn’t get much of one myself,” I admitted.
That made her lip curl again. “How dirty you are, cumming for your own sister like that.”
“She didn’t give me a choice.” I replied, reaching for her chin. She let herself be pulled in for the kiss, but didn’t let it last long.
“Come on, off your lazy ass.” She climbed over me off the bed.
“Don’t you want… I could… uhh…” I wasn’t sure how to ask. Post nut clarity set in, and though there was no guilt, I was all at once aware of the fact I was trying to ask my sister if she wanted me to get her off. It made me weirdly self conscious.
“Later. That just now, we’ll call that the massage tax. I only came up here to get my swimsuit,” Liv started changing, pulling her crop top off to reveal a modest sports bra. “Your thing just happened to be so… in my face. I couldn’t help myself.”
She pulled her bra off too, revealing her two perfect breasts. Even spent, my dick twitched at the sight of her topless.
“We’re wasting daylight. I just got the healthy scrub down, time to ruin my skin again with more radiation.” Liv put on her bikini top, then pulled her bottoms down in one go. She wasn’t kidding, and I only got a brief glance at her bare pussy lips before her bottoms were on.
“You kinda made a mess over here.” I told her, looking down at my sticky nether regions.
“Oh I did, did I? So that’s my cum all over you?” She put a hand on her hip, giving me a look.
“Hey! I was just laying here, minding my own business…”
“And you’re welcome to stay there.” Liv blew me a kiss, grabbed the sun screen and left the room, climbing down to the main floor. “But your hot sister is going to be out in the sun, waiting for someone to do her back! And she’s not planning on keeping this suit on for long!” She called back up to me.
