Liv and I lay motionless for a second longer, breathing again, but not yet relieved of the tension. After a second longer, I glanced back at the door. There was no longer light coming from the main room, they’d flipped it off. Sighing, I pulled myself forward into Liv, spooning her, and bringing my arm around to hug her from behind.
“Fucking dad.” She whispered.
“Fucking dad.” I agreed, nuzzling my nose against her neck. My dick had gone down somewhat at the interruption, but now, nestled back against my sister’s firm ass, it quickly regained its size. Liv let me kiss her, turning into me slightly. I got the feeling that if I’d asked, she would have resumed her blow job, but I could also tell she felt more secure under the sheet. And as she wiggled her ass, raising her leg slightly until my dick was trapped up against her wet slit, I didn’t mind it at all.
I was too worked up from Liv’s brief head to wait. I lifted her leg with my hand and grabbed my dick, rubbing it against her. It took me a few tries to find her opening in the dark, and she sighed huskily as I slid my length along her sex. Finally feeling the telltale give, I slipped into her. Her pussy was hot and wet, and because of the position on our sides, gripped me hard.
“Uhhh..” Liv gasped as I entered her. She turned her head to kiss me. I started fucking her slowly, my dick in heaven as it moved smoothly in and out of my sister. She looked back at me in the dark, taking a second to make eye contact. “I’ll make it up to you.” Her voice was so quiet, I almost didn’t hear her.
“You’re making it up to me right now.” I whispered back.
“Still… uh.. I will…” Liv got out before she curled into herself, putting a hand on my side, feeling me inside of her.
It was incredibly sexy fucking her from the side, in the dark, with very little visible. It amplified the feeling, putting the focus entirely on the sensation of fucking Liv. Her insides flexed around my cock, and I felt myself getting closer. I increased the pace as best I could, a bit awkward because of the angle. My balls ached as I approached my orgasm, and I felt my dick leaking precum. I was almost there when I became aware of a faint wet sound coming from our fucking. Olivia was aware of it too, and put her hand on my leg to slow me down.
I forced myself to stop, not able to just slow, not with how close I was. It took a herculean effort. I think Liv felt me trembling. She couldn’t help herself, letting out a small snicker.
“You’re so evil.”
“I know.” She replied. “Were you close?”
“What do you think?”
“I think we just prevented you from making another mess. Good for the sheets.”
“Fuck you.”
“Please. But quieter.”
I didn’t need another invitation, starting up again, careful to listen for any betraying sex noises. It was the third time now, but fucking Liv was as surreal as it had been the first time, the night before. There was some confusion in me still, but more than anything, it just felt good. Eventually I found a good rhythm, fast enough to get me there without being too loud.
“I love having you inside of me…” Liv breathed.
“I know baby…” I murmured, feeling my orgasm coming on. “I love… uh… being inside of you… uh…” I panted. My brain blacked with pleasure as I climaxed inside of her. I felt the cum well up and spurt into Liv, my dick twitching with each release. Instead of fucking through it, I held myself still, letting my orgasm overtake me while fully buried in her. I shuddered as it faded, becoming aware of how hard I was pressing myself into Liv’s body. We were incredibly close, touching as much as we possibly could in the dark.
Liv gave me another second or two to recover before moving. She flipped around to face me. My dick slipped out of her when she did. I felt the wetness as my mess leaked from between her legs. Neither of us cared. She pressed up against me again, nestled in my arms. Still a little shaken by my orgasm, I loved that she did that. I thought about us talking that afternoon, what we’d said. Not having to worry about exactly what we were to each other. Not having to worry about the other only being in it for the sex. Not having to worry about not being cared for. I hugged her close.
“It’ll be so nice when we’re home…” Liv said after a bit, breaking the silence.
“Whaddya mean?” I mumbled. I’d closed my eyes, enjoying the feel of holding her, almost dozing off.
“They won’t be able to hear us from my room. We won’t have to be so quiet…”
Olivia’s bedroom was above our garage, a late addition to our childhood home. It was also two floors and a length of a house away from our parents’ bedroom. I knew exactly what she was suggesting with that comment.
“No, they won’t,” I agreed.
I slept very well that night.
**
I woke to the dull pattering of rain on the skylight. It was early morning, and we were definitely not going fishing. Liv was still next to me, naked and sound asleep. We’d gone back to spooning at some point in the night, and I had to slip my arm out from under her in order to get up. She murmured in her sleep as I separated from her. It was a really cute sound. I had to pee though. Getting out of bed, I pulled on boxers, and went down into the bathroom.
My dick was messy from our night’s activities, and after taking my piss I realized I felt dirty. I turned on the shower, and slipped back upstairs for my towel. The ladder was loud as always, I hoped I wasn’t waking everyone in the cabin by going up and down. I glanced at Liv’s silent form before heading back downstairs. I seemed not to have distrubed her, at least.
I took a fairly quick shower. It was still early, I just wanted to freshen up, and had every intention of getting back into bed with my sister before our parents woke. I wrapped the towel around my naked waist after drying off, and climbed the ladder one more time.
Liv was awake now. She lounged casually on her side, head on her hand, the blanket only covering her from the waist down. She was scrolling her phone when I opened the door, but put it aside to watch me.
“Where’d you run off to?” She asked, her voice playful.
“Shower. I was all dirty for some reason.”
“For some reason.” Liv gave me her customary mischievous look. “And here I was planning a surprise for you.”
“A surprise?”
“I was planning on waking you up with a… in a certain way.” She pouted. “Guess not.”
“I could go back to sleep?” I shut the door behind me, and dropped my towel. Liv’s eyes looked my naked form up and down. I scrambled onto the bed, getting under the sheet with her as I went.
“You think you could? I don’t know…”
“I could just pretend.” I lay on my back and shut my eyes. “See? Asleep again.”
“Hmm, that might work.” I felt her start to move and cracked an eye open. “Hey!” She scolded me. “No peeking. You’re asleep.”
“Yes, ma’am, sorry.” I said, promptly screwing my eyes shut again, smiling.
I felt Liv move around til she was by my lower half, crawling under the sheet. She ran her nails along my legs as she climbed between them. It went without saying my morning wood had gone down with the piss and shower. Now it fully returned, my dick standing straight up, hard and ready.
Liv had no plans to tease me. A small hand grabbed my length, accompanied almost immediately by the warm softness of her mouth. She sucked the head with a small pop, swirling her tongue and stroking me. I groaned. I couldn’t help it. I heard her giggle. She licked my length before taking me back into her mouth, using her hand to add force to the feel of it against her tongue.
Opening my eyes now, I threw the sheet back to reveal my naked sister with an innocent look on her face and half my cock in her mouth. She bobbed her head up and down twice, then let me slip out, and gave me a smile as she worked my shaft with just her spit covered hand.
“Look who’s awake,” Liv said.
“Really?” I laughed quietly at her. “That was the best line you could come up with?”
“Oh sure, make fun of the girl sucking your cock.” She rolled her eyes.
“I’m just saying, you said you planned this…”
“And it would have gone over great if you weren’t awake,” Liv insisted. “You’re lucky we got interrupted last night. If I didn’t feel like I owed you, I’d probably stop.”
“Good thing you owe me then.”
Lic shook her head and, instead of responding, took me back into her mouth, working her lips up and down my hardon. Liv knew what she was doing. And that combined with the pure hotness of watching my sister gag on my dick, was plenty to keep me riled up. She was hesitant to deepthroat the whole thing, but would easily take most of it, letting me slide wetly in and out or her mouth. I was hesitant to really fuck her throat, not comfortable with the thought yet, but did take a handful of her hair, and help her head work up and down. She took a break to suck on my balls, lifting them into her mouth as she jacked me off with increased force.
When she fastened her mouth around me again, spit all over her chin, my dick and balls a sloppy mess, I could feel myself getting close. I grunted again, making eye contact with her as she blew me. Her hazel eyes stared into mine, and she started going faster, gripping tighter with her hand.
“I’m going to cum…” I whispered.
She didn’t stop, didn’t even slow, instead just continued to aggressively jack off the base of my dick while sucking the head. Her eyes stayed locked on mine.
“Oh Liv… fuck…” I mumbled as I came in her mouth. My cock throbbed and twitched, I trembled as I orgasmed, watching the cum leak out from around her lips. Liv didn’t spit, but she let a few drops go, opting to stroke me through the orgasm rather than keep me locked in her mouth. It was intense and electric, and the image of my dick twitching in my sister’s mouth, with spit and semen running down her chin, burned itself into my brain forever.
