Back to Civilization

I woke up the next morning sweaty from having shared a sleeping bag with my sister. I didn't feel any guilt about having broken the ultimate taboo. Not a single scrap of it. Cassidy felt like my girlfriend as much as my sister now and I loved it. She didn't seem to feel any regret either as she made us coffee and I cooked bacon and eggs over the camp stove. We broke down camp and went on a big hike for the day, about seven or eight miles to actually complete the trail we'd started the night before, and end up back at the parking lot.

We didn't talk about much in particular at breakfast or on the hike. We played music over the portable speaker so we could both listen, and when we did talk she just complained about her sore feet or whined that the water we'd brought wasn't cold. Well what did you expect on a hike, you brat?

We decided to spend Saturday night in the one halfway nice hotel in the area, a park lodge set back in the woods not too far from where we'd hiked. Mom and Dad took us there as kids and it was a real treat, since we were used to camping in the woods. I guess some kids have childhood memories of Disney World vacations and our parents did take us there once (I got lost for an hour and Cassidy was crying when they paged me over the loudspeaker and I found my family again). Most of our vacations were just off in the woods though, and you know what? We must have liked it, considering that Cassie and I recreated such a trip for our first mini-vacation as adults.

The lodge is hardly a five-star place but it's still pretty nice for the middle of nowhere. Each room has a balcony with a serene forest view, and there's a lake, pool, hot tub and all sorts of other fun stuff. We loved this place as kids and going back felt nostalgic in the best kind of way. I unlocked the door to our room, which was a fairly generic, but clean, hotel room.

"Ah, finally a room worthy of a lady," Cassidy said as we entered.

"Where's the lady?" I teased.

"That's it, you're sleeping on the floor tonight!" she hollered.

I looked into the hallway nervously, but nobody was there. It's not like they'd have known we were brother and sister anyway. Nobody here knew us. It made me think about something.

"Hey Cassie we could move somewhere else and nobody would know we were siblings. We could just be a normal couple," I said.

"Don't be ridiculous, moron!" Cassie said as she dropped our suitcase on the floor with a thud. I thought it would be a sweet proposal but I clearly don't know how women's minds operate, as we've seen before. Even though I assumed as a vagina-owner (is that the accepted word for a woman these days?) she'd like all the mushy romantic stuff, but she didn't seem to like it at all. She just wanted to be bickering siblings still, even after our passionate night in the woods. Well, that was better for me actually, I'm no Romeo, so I was happy to bicker with Cassidy if that's what she wanted. You might say that dynamic was what fueled our whole relationship - she acted bratty, I tolerated it until she went too far, and then I gave her one hell of a punishment, and we both loved that part best of all.

We settled into the room and she sat on the balcony (the only place with good cell reception) to update her social media. As she is a streamer that stuff is actually important for her job, she wasn't just being a zoomer needing to check in on Insta and Twitter every 5 seconds. We got dinner in the lodge's restaurant. It was pretty crammed with people since this was peak season, an awkward mix of romantic couples and families with kids, the two demographics to go see the fall colors in the beautiful wilderness I suppose.

Since we'd spent most of the day hiking, it was already dark by the time we got back from dinner. We sat out on the balcony listening to the crickets and feeling the cool autumn breeze off the trees. It was nice, but Cassie wasn't doing anything flirty with me, and when I took her hand she didn't seem that into it. I guess she really didn't want a typical boyfriend/girlfriend thing, at least not yet. She didn't seem like she was traumatized or anything by the treatment I gave her the night before, so it wasn't that, when I asked her about it she said it was fine and she'd liked it.

I left her out on the balcony to go take a shower before bed. The bathroom like everything was clean and cozy, if not luxurious, with mid-range beige tile and a glass shower door. I turned the hot water up the way I like and was soaping myself up in back when a wave of icy cold swept over me. Someone (gee I wonder who?) had dumped what felt like an entire bucket of water on me. And it wasn't just cold water, it was half filled with ice cubes, I could see them floating down toward the drain.

"Aaah!" I screamed in surprise, "What the fuck?"

I heard Cassie laughing then the bathroom door slammed. My sister did love her childish pranks, but this one seemed cruel and unnecessary, totally ruining my relaxing shower. I shivered and hopped into the flow of water to warm myself off, then rinsed off the soap and turned off the shower.

Okay so it was just cold water, but it felt like a humiliating insult. Which I'm sure was by design, but I couldn't let it go. I was mad. I wanted to punish my sister for this.

Cassie was laying on her back on the bed, dinking around on her phone like nothing happened.

"Up!" I said. I was naked, having just dried off quickly so I could come out and punish my sister, sparing no time to get dressed.

She looked at me and giggled, a little nervously. She was probably thinking over whether she could say something sassy, but I clapped my hands loudly and that seemed to spur her into obedience. She jumped to her feet by the bed, but said, "It was just a prank, Mike!"

"It's not very nice to play a prank on your master," I said, as sternly as I could. I knew I had to sell it so she didn't laugh and ruin everything.

Even still, I think she almost laughed, but perhaps she feared upsetting me. Or maybe she even actually respected me now (ha ha). She wiped the smile off her face and said, "I know, master. I'm a bad girl." There was some sass in her voice to be sure, but on the whole I was pleased. Taming my bratty sister always made me horny and fired up my sadistic urges.

I bolted the door. Doing this in a hotel room, I knew we'd have to keep the volume reasonable. We'd lugged in some of our supplies and I found the duct tape I used for quick fixes to the camping and hiking gear. Cassie looked at me wide eyed and fidgeted as I taped her mouth shut, but she let me do it. I'd have to figure out a better way to gag her, but this would work for tonight. Something about how she stood still and let me tape her mouth shut got me even hornier than I had already been.

"Can't have you scaring the neighbors while I punish you. You look sexier with your mouth taped shut anyway," I said darkly. It was just bedroom talk, although she did look pretty good that way. "Take your clothes off."

She balked at this, but that felt right. If she was a total pushover it would take the fun out of this. I grabbed my forcibly muted sister and pushed her down on the bed, taking her clothes off from behind as she struggled with me. I was still uneasy about forcing her like this, I never wanted to actually rape her, but the feeling of force nevertheless gave me a huge boner every time.

I stood her up naked and looked at her nubile body. I'd never not be turned on by her tits and shaved twat. I decided to make sure she was into this and crudely reached between her legs, fingering deep into her cunt. She was soaking wet. I smirked. "You're horny, huh?" I asked, stepping back. She blushed and nodded.

"Damn you look so sexy with your mouth taped up," I said, repeating myself, but I couldn't get over how exciting it felt to gag her. I think she was having the same reaction since she'd stopped resisting now and was standing naked before me, her nipples rock hard. I saw her eyes dart to my crotch, no doubt noticing my own hardness.

I took my belt from my pants but instead of whipping her with it, I used it to tie up her hands behind her back. We'd gotten a bucket of ice which I now saw she'd mostly dumped on me, but a few ice cubes were left. I rubbed them around her nipples, squeezing her nips between two cold cubes, freezing her as much as possible. Then I slapped her breasts hard with my backhand and heard her yell, but the tape muffled her nicely. She stood rigid while I slapped her breasts hard, the pain making both of us horny.

Once I'd gotten her breasts beet red from my slapping, I had her lay over the bed, presenting her ass to me as high in the air as she could get it. I had her in such a vulnerable position and decided to complete my icy revenge in a novel way: I shoved the remaining ice cubes up her asshole. I put them in one at a time, shoving them in with my fingers, forcing them past her anus and into her ass. For her part, Cassie yelped in surprise at the strange anal sensation, and shivered as I filled her ass with ice. It was had the desired effect of making her feel much colder than she'd made me feel before the ice quickly melted and water dripped out of her ass, which managed to make even my sister blush in embarrassment.

I flipped her over again onto her back (and bound hands). She seemed very aware of her powerlessness now as she lay there bound and gagged under me. Again she looked to my hard cock. "Are you wondering if I'm going to rape you?" I asked sadistically.

She nodded yes.

"Well, do you want me to rape you?" I asked her, keeping my voice metered to a conversational volume. This was no cheap motel but even still I hardly wanted our neighbors to overhear.

I hear her yell a very muffled "Moron!" through her taped mouth.

I slapped her tits hard again and she winced in pain. "Do you want this or not? I can just jerk off," I said. She nodded yes and spread her legs. It wasn't much of a rape, but perhaps that was not the healthiest thing to be playing out every night. I slid my cock inside her warm pussy. "You're even wetter now, Cassidy," I said, "You're a pain slut." She rolled her eyes, but moaned into the tape as I started to fuck her.

Sex with my sister felt so right. Her cunt was warm and wet, just tight enough to feel amazing. This overtly willing version of Cassie was even better than the one last night, I liked her being eager to have incest with me, even bound up like this. I pushed all the way into her then ripped off the tape mercilessly and kissed her on the lips. She moaned into my mouth as I fucked her, her hands still bound so she just had to take it, but she clearly loved this.

I slid in and out of Cassie's wet vagina. She moaned loud but also seemed to be trying to avoid being overheard next door. I looked at her tits, still red from my slapping, and hit them again.

"Fuck!" Cassie said, "Whip my tits, master!"

Sometimes I thought she was more into this than I was. I slapped her tits again and again as I fucked her. Hurting my sister while having sex with her was too much for both of us. She came before I did, moaning in delight as she looked at me intensely. I wanted to cum inside her so badly but again, that would screw everything up. I pulled out and crawled up onto the bed.

"No, I'm not a porn star! Don't cum on my face!" she yelled at me.

I laughed. "You're my pornstar, Cass," I said, and gave myself the last few strokes I needed to cum, shooting my sperm all over her beautifully annoyed face. I pressed my cockhead into her mouth and jizzed on her lips and teeth as she yelled at me to stop. Only as I got all my sperm out did she finally calm down and swallow my cum for the first time.

"Moron," she said with a grin.

I untied her wrists and we lay there on the bed naked. "This is great," I said after a while, "Too bad we have to go home tomorrow."

She shrugged. "Let's just enjoy tonight."

I agreed and hugged my sister tightly. We'd enjoy tonight very much.
