“Sit back down.” I told Anna. “Don’t let her mess with you.”
Anna gave me a look, then surprised me by listening, and sitting back down next to me. I didn’t think she’d let it go that easy. “You’re right. She’s just jealous of how cute we’d look together.”
“Jealous? He’s my brother.”
“Yeah exactly, and your brother’s hot. Hence the jealousy.” Anna pushed up against me again. “Can’t imagine how frustrating it’d be to have this hunk around all the time, and not be able to do anything about it.”
My eyes narrowed, Anna’s remarks a little too on the nose. Would Liv have told her? I dismissed the thought immediately. No way. Besides, in that case there’d be no reason for the innuendos, we were the only three in the hot tub. As if responding to my thoughts, Anna let me go, giving us some space again.
“Sorry guys, I thought I was going to be getting dick all week in summer paradise. I’m just a little frustrated.”
“I get it.” Liv said. “Though be careful or you’ll leave Will confused.”
“Shut up.” My turn to roll my eyes at my sister.

We stayed out on the deck for maybe an hour or so, rotating in and out of the hot tub as we overheated. At one point I hit the jets, which made it a lot easier to manage my erection underwater, and whenever I got out I could just put the girls to my back. Not that I was worried about Liv seeing it or anything, more I didn’t want Anna misinterpreting things, especially after she’d flirted with me so overtly. The existence of Jake also made me extra mindful of not letting anything go too far. Anna grabbed my arm a few more times, but that was it.
When we were all ready to go in, we dried off and headed to the living room. I sat in an armchair in my towel, meanwhile Liv and Anna shared a couch, and we watched some netflix comedy special. It was hard just sitting there and watching TV. I desperately wanted to talk to Liv about where she was going to school. Thinking about it, I was met with a mix of emotions. She’d be close by. What did that mean? I wasn’t sure.
“Do you want to shower?” Anna asked me, snapping me out of my thoughts.
“Sure.” She showed me where the towels were and how to operate the shower in the downstairs bathroom. Then her and Liv went upstairs and into her room. For a second I wondered if I shouldn’t have just gone home with our parents. Nothing wild had happened, not that I’d really been expecting anything. The pitch for the evening had seemed much more risque than it wound up being.
I thought about jacking off in the shower, still worked up from ogling Liv and Anna, but was too caught up in my thoughts. Eventually I decided if I needed I had my own room tonight, and could always finish later. Turning the water off, I dried and put on my boxers. Feeling a little risky, I decided to go upstairs in just my underwear. Unfortunately, I ran into no one. I could hear Liv and Anna talking in Anna’s room, and Marie had long ago locked herself away in the master. Resigned to my fate of another boring night, I got into the previously unused bed. Granted, it was really nice to be sleeping in air conditioning for a night, between crisp sheets. I stared at my phone for a while, but before I knew it, I was drifting off.
**
I woke up in the dead of night, to the pressure of a body against me, and a hand wrapped around my cock, working it up and down.
“Hmm, took you long enough.” Liv whispered. She leaned down and kissed me, pulling the last bit of my consciousness out of sleep. I opened my eyes to see she’d pulled the sheets down and my boxers off. My sister was in a large shirt and panties. The door was shut.
I sat up, grabbing at her under her shirt, pulling her close. She giggled at my lust, working my dick as we kissed. I fumbled at her boobs, feeling my heart beat rapidly in my chest. I’d missed her mouth on mine, her soft wet lips, the tenderness in how our tongues explored each other.
We kissed and groped, and then I kicked my boxes off my ankles and pulled Liv down, so that she fell on top of me. The weight of her across my body felt extremely comforting, I was bigger than her to the point where she could lay on me, completely off the bed. My dick throbbed against her, trapped by her stomach for the moment. My hands pushed her shirt up and grabbed her sides, feeling her bare skin.
I nibbled her ear. “I missed you.” I said huskily.
“I missed you too.” Liv whispered.
She propped herself up on my chest, and looked into my eyes. “Sorry, I didn’t mean for you to find out about Emerson from Anna.”
“It’s okay. Why didn’t you tell me you applied?”
“I don’t know. Well, obviously it seems stupid after the last few days. But before you came home, it had just been a while. I wasn’t sure if you’d be thrilled to have your little sister around.”
“I am more than thrilled.” I kissed her hard on the chin. “But I suppose it does make this more complicated.”
“Right. Not like being in a different state makes us not siblings.”
“We could fake it, I guess. But what happens when they see pictures of us together? And my friends have seen my instagram, they know what you look like.” I shook my head. “No, it wouldn’t work. Might be able to fool people you’re meeting, but no one I know will fall for it.”
“It would be weird for you to introduce me as your girlfriend, not your sister.” Liv said. “And if I’m different things to different people, it might get confusing.”
“And there are too many social media detectives,” I sighed. “Might cause us some… social problems, for sure.”
Liv giggled, nuzzling in my collarbone. “To put it mildly.”
“So we’ll be close together, but still siblings.” I said.
She nodded slightly. “Really close siblings.”
“The closest.” We kissed some more, my hands found their way under her panties onto her ass. Liv started grinding herself against me.
“So what do we do in the meantime?” I asked her when we came up for air. “We said maybe we can’t leave this until we get home.”
“Well I plan to keep fucking you. Even when we get home.” Liv said matter of factly. “Unless that’s an issue for you?”
“Nope. I can do that.” I said, matching her tone. “How else am I going to spend the summer?”
“I don’t know,” Liv leaned down close to my ear. “But deep inside your sister sounds good to me.”
The words had barely left her mouth before we were all over each other again. I pulled on her shirt until she allowed me to get it over her head. Now topless, Liv leaned down and kissed me while holding my chin. I fondled her naked breasts, loving the feeling of them in my hands. My dick was now trapped by her crotch, separated from her pussy only by the thin material of her panties. She continued grinding against it, gyrating her hips. I could feel her wetness through her underwear.
“I’m going to sit on it.” Liv whispered to me, her voice heavy. I had no objections.
She got off me for a second, hurriedly sliding her panties off to join me in the nude. I scooted myself up, propping pillows behind my back so I could sit more comfortably. A second later she resumed her position, straddling my cock, this time nothing separating us. We kissed some more, and she started grinding against me again. Her wetness was thrilling, for the moment my cock stayed simply rubbing against her slit, sliding up and down with her hips. Not wanting to wait any more, I grabbed her waist, and helped lift her up. My sister reached between our legs and positioned my head at her entrance. I felt the tip slip into her, and then she was lowering herself, and I was in heaven.
My dick throbbed as Liv sunk down onto it, her warm and wet insides pure bliss. Liv let out a soft gasp, pushing her hands into my chest. We stayed like that for a moment, my entire length buried inside of her. I reached up and caressed her face. Liv leaned into my hand, letting out another sigh of pleasure as I twitched inside of her.
Leisurely, Liv started to ride me. She rocked back and forth, continuing her grinding but with me now inside. I let her control the pace, content to play with her boobs and ass as she pleasured herself on my cock. There were only two windows in that room, but they let in enough light for me to see fairly clearly. It was incredible, watching my sister, her slender body writhing in ecstasy atop my dick, her face aflush in the dim light of the moon. Eventually, I started to help, bucking my hips to thrust up into her. She responded quickly, her toned stomach flexing as her legs started working to bounce the rest of her body up and down. The increased friction was electric, and I moaned as my cock responded to it.
We did our best to match rhythms, but I could tell Liv was leaning more heavily into the grinding. That was fine by me, without the breaks in the thrusting my underused dick would have erupted much faster. Both of us were breathing loud, our breaths ragged. Liv was letting out occasional moans. Little sounds, they were almost a purr, and were particularly cute. There was a voice in the back of my head saying we were too loud, but I dismissed it. We weren’t in the tiny cabin anymore.
Feeling myself getting closer and closer to cumming, I decided to take control. Gripping her hips in my hands, I started to direct her up and down, lifting her amazing ass off my dick as I thrusted, working to match our flows into one. I started thrusting harder too, really fucking her, going hard and fast. Liv trembled on top of me, her body quivering.
“Fuck…” I murmured. “I love you being on top…”
Liv just nodded, her eyes losing focus as I pounded up into her.
“I’m gonna cum…” I warned her.
“Cum in me…” Liv gasped. I was starting to think she liked the feeling of me filling her up. I wasn’t going to complain.
“Fuckkkkk….” I moaned as I reached the brink of my orgasm.
Lost in our ecstasy, neither Liv nor I noticed the door opening.
