The campground is just outside the park and it is beautiful. It is up on a ridge but it's flat and grassy. There are RVs and some tents, but everything is pretty spaced out. On the edges of the campground are the tiny little shack like cabins with a firepit out front and some cots on the inside and it overlooks the town of West Yellowstone, Montana (creative) which is very small and surrounded on all sides by planes and mountains and sometimes you can hear howling that is probably coyotes but we can pretend its wolves.
If you were feeling up to it and if it wasn't too late and it was cold enough I would build a fire, but it's really nice to sit in the intense darkness and hear how small your voice sounds when you use it.
I'd sit too close to you while we sit and stare out at the view and pretend it was colder than it was and try to get you to tell your life story, or a story. Either, or both. I'd lean into you and feel your voice rumble its way out of your chest and breath you in while I quietly fill up with wanting you.
You'd put your hand on my face when I hadn't noticed you were done talking, and nudge my chin up to look at you while you leaned in and pushed your lips against mine. You would bring your other hand up and into my hair and push your mouth hard into mine and slip your tongue between my lips for a first taste of how warm and wet I was.
You would finally pull back and I would probably do something awkward like laugh and put my hands on my face, relieved it was too dark to see how red I turned.
Someone, but it wouldn't matter who, would suggest going inside. One of us would carry a flashlight and we'd step inside our closet sized cabin and close the door and it would be impossibly dark and quiet and your hands would find their way to my hips and turn me towards you. You'd kiss me again and harder and pull into you so I could feel your cock. I'd moan into your mouth and push myself into you and grind my hips against yours. I'd pull away so our lips just touched and ask, "please?"
You'd smile and slide your hand under my shirt and over the soft fabric of my bra cupping my breast while I pull off my shirt to accommodate you. You'd undo the hook of my bra deftly while I tugged at your shirt, eager to get it off.
Once we got each other's clothes off you'd sit on one of the cots (which I should clarify are like wooden platforms with cushions on them that are a bit less than a twin bed) with your back against the wall and I'd climb over you, and let my mouth trace a trail around your neck and shoulders and nipples while I reached down between us and use your cock to circle my clit so I'd be wet on my own and with your pre-cum.
When you couldn't stand it anymore and I was close to cumming I would slide just the head of your cock into my soft, wet pussy until you put your hands on me and forced me down, hard, and feel my pussy squeezing your cock in rhythm with my thrusting hips.
I would put my hands on either side of your face and run them down your neck and chest while I rode you, cumming and shaking in your arms. You would finally grip my hips and pull me hard into you so you could cum deep in me while I dug my fingers into you gently with one last, shuddering orgasm.
If this were just porno then we'd probably gracefully fall asleep in each other's arms. But it's not, this is travel planning, and it strives for realism.
So I would probably fall into you laughing and burrowing my face into your shoulders and gasping as you pull out because every time you move my sensitive pussy starts to cum again. One hilarious clean up later, and if you wanted to, I'd wrap myself around you and go to sleep.
There are lots of things to do in Yellowstone, but I think in this scenario we'd get up early, and go to Lewis Lake and rent a kayak. We could backpack, but I don't want to hurt your knee. I once twisted an ankle backpacking 25 miles from the nearest civilization and there was nothing to do but suffer and I don't want that to happen to you. So kayak is maybe a safe bet and fun, I'd slide in behind you and put my legs on either side of you, and when you felt like it you could lie back and enjoy the sun and putting your feet in the water, and the spray that comes off the paddle while we float along to the river that connects Lewis Lake and Lake Shoshone. I think you might have to portage there, but if there's enough water we can probably wade and just tow the kayak, and there would be trees around us and these enormous mountains high above us. Once you get to Shoshone lake I hear there are geysers just on the shore so you can paddle past them while they fume. The trip leaves plenty of time to find a campsite in the shadow of a mountain (which I'll make sure to get a permit for).
