[m/f] Anal for the Environment!

tl;dr: met a super hippie chick & we had anal. the end.
OK, there's more to it than that. I took a gap year between HS and my first year of college. But my parents weren't going to let me just melt into the couch cushions and play video games all day. So I applied to an internship with a forest management company in the NW. Basically, my job would be take bark (and other) samples. Which sounds simple but had a few technical twists, like knowing how to read a map, identifying tree species, and not getting shot by hunters. I was unskilled in all of the above, but my dad is a lawyer and knew a guy who knew a guy. So I got in. Yay. Eight months at less than minimum wages plus guaranteed Lyme disease!
We got two weeks of training and then they sent us off in sets of three. One trained researcher and two highly inept interns. The first week was just me and two other dudes. But the second week, a new researcher showed up in base camp to replace my first researcher (because he tried to chop his thumb off with a hatchet- and almost succeeded). Her name was Teija, but we just called her "Ty" or "Tay" (mostly "Tay"). She was Finnish, on a research visa, and about 28. Blonde hair so fine it was like silk when she let her braids down. Her eyes were that shade of blue that you see in glacial ice. Skin so pale it was hard to believe she didn't live in a perpetual state of sunburn. Cheekbones that made it obvious where Tolkien's version of elves came from. And a rocking hard body from all the hiking and climbing that the job required.
The first thing Tay did when we set up our first satellite camp was to take her shirt off. As I had done the same thing about two minutes prior, the only reaction I could have was to shrug and chalk it up to "crunchiness" (an adjective our group had agreed upon to mean "in tune with nature" or "like a hippy.") She noticed me not making a big deal about it, and nodded approvingly. Then she offered to spritz (spray cans weren't allowed) me with DEET skeeter repellent. When she was done, she handed me the bottle and held her arms out at her side. I tried VERY hard not to notice her nipples getting crinkly when I spritzed them.
The other dude in our trio was from New Jersey. He was a sort of awkward non-crunchy guy who would have been more at home melting into his parents couch and playing video games. So, kinda like me but not as good as hiding it.
That week, we collected samples, took measurements, platted populations, and did some minor conservation (trail maintenance, mostly). Tay took the lead, having done this many years. After a while, seeing her b-cup-ish sized tits swaying back and forth became unremarkable. When we crossed paths with other trios, we'd get weird looks. But I guess the word got around, and even that faded away.
Then the day came when Steve (the other guy in our trio) tripped and landed his knee on a sharp rock, breaking his patella. It wasn't pretty. Fortunately, Tay knew how to make a travois. We dragged him, screaming, 15mi back to base camp where he got airlifted out. There wasn't anybody else there at the time, so we slogged back to our satellite camp. Tay and someone in charge argued back and forth over the radio about the rules only allowing trios or quartets in satellite camps, but what could you do? There wasn't anybody available.
You should know that Finnish people are kind of standoffish. I guess it's just the culture. Tay explained it by saying that if they don't have anything to say they don't like to fill up the space/time with words. Or something like that. She (like most Finnish people) spoke English better than we do. But it's hard to translate idioms, I guess. One-on-one, after they get accustomed to other people, they will open up. And as Tay said: beer helps.
Which brings us (finally) to the sex. Two days after the unfortunate Steve broke his knee, we came to a place where two beautiful little streams mingled to form one slightly larger (and just as beautiful) stream. "Wait here," said Tay, wading in up to her waist. I did try to not stare at how the cold water affected her nipples, but only being junior-crunchy I did not have the will power. The oft-quoted term "glass cutters" did not do them justice.
Reaching under a bed of moss that jutted out over the stream, Tay pushed and prodded and eventually pulled out a large mesh bag full of silvery cylindrical objects. She grabbed one of them from the bag and yelled "Catch!" as it hurtled toward my head.
Surprising the entire Universe, I snagged it out of the air. It was beer. The cheapest, nastiest, most generic-label beer ever manufactured, but still beer. I'd been in the woods for five weeks drinking groundwater purified by tablets that might have been suppositories for all I know. That beer was ice cold liquid heaven to me. I made love to that beer. I worshiped its watery godliness. I was so intent on guzzling it down that I didn't even notice that Tay was completely naked. Wait- what?
Yep, about 20 feet from me was an Ice Goddess. Her hair was unbraided and wet, plastered to her back and chest. Her pussy was just barely covered with thin golden wisps. She was bathing herself by dipping her hands in the water and letting it trickle down on her. And I swear I have never seen nipples so erect in my entire life. I was sure they'd start shooting laser beams.
"Come on in- when you get to take a bath on this job, you don't waste the chance," she yelled at me over the sound of the rushing streams. I hesitated a little- until now, she'd been very straight laced (albeit topless) and formal. The idea that Tay could have a playful side was a little disconcerting. Seeing her lie back in the stream with just her breasts and pelvis above water settled it.
I shucked off my shirt and shorts, carefully set my boots and socks by a tree, and waded in, cleverly hiding my growing erection by coming in edgewise to Tay. I needed have worried. The ice cold water took care of THAT for me. "Careful of the bottom," she cautioned. "If you cut your foot on a rock, it'll be an uncomfortable few days." I nodded, coming close enough to her to be "sociable" but not so close that it would be misinterpreted.
Tay reached into her pack, which was at the edge of the stream, and pulled out a small bar. "Biodegradable," she explained, lathering it up. Watching her wash herself was… fascinating. "Do my back?" she asked, handing me the bar.
Time to fish or cut bait. Cautiously (I still wasn't sure if this was a friendly seduction or just basic hygiene), I soaped up her back. When I was done, I filled my hat (which I had just remembered forgetting to take off) with water and splashed it on her back.
"Aieeeiiiii!!!" Tay shrieked. "I'll get you for that!" She turned around and started splashing me in revenge. That water was COLD!!! I broke out of my shell of caution and started splashing back, laughing and getting laughed at in return.
After a short but very satisfying water fight, Tay dunked herself back down to rinse off and then said "OK, your turn. Give me the soap." At first, she was very no-nonsense. She washed my back, and then the back of my arms, and then my underarms. She made me dunk myself so she could wash my hair (putting her breasts exactly at eye level).
When everything above the waterline was clean, she stopped and sighed.
"Men," she said. "It's not just the Finnish ones who can't take a hint." And then she leaned closer in to me and reached down below the surface of the water.
I gave a little yelp of my own. Her hands were anything BUT no-nonsense as they played with my cock and balls. She paused for a moment to soap back up, washing me thoroughly. Then she handed it back to me and said "now me- I don't want to get crotch rot, you know."
She kept playing with my cock and balls while I washed her pussy. Her inner lips felt perfect. Just big enough that you knew they were there and could play with them, but not so big that they'd be a problem during sex. A few seconds later, I gave her clit a few well-timed flicks, causing her to give a little gasp and then giggle- the first time I had heard Tay make any sound like laughter. After her front was done, she completely surprised me by turning around, bending over, and pulling her cheeks apart. I didn't have to be told twice- I lathered up and gave her ass a thorough cleaning, paying special attention to her little rosebud. I'm not a fan of that sort of attention on my own back bits, but Tay insisted. It didn't feel THAT bad.
We got out to drip dry, using a patch of grass to lie down on. Each of us downed another nasty (yet wonderful) store-brand beer before re-caching it for later. Then Tay put her head on my shoulder and fell asleep while idly playing with my cock.
When I woke up, my cock was being sucked by a very enthusiastic blonde goddess. It didn't last long, though. Tay saw that I was awake and then quickly switched to a 69 position. Stream-washed pussy tastes SO much better than regular pussy. You really should try it. We ate each other out for a few minutes, and then Tay climbed off me.
"Fuck!" she screamed. "I fucking want to fuck, but I didn't bring any condoms on this trip!"
I said I hadn't either, but I'd be happy to eat her out until she came. No strings attached.
"No, fuck that," she replied. "I want you inside of me." Then she started digging through her pack. "Perfect!" she cried, looking at me with a gleam in her eye. "Lie down again. I'm going to ride you."
She poured sort of oil in her hand from a plastic tube. "Coconut oil," she explained, "I normally use it for sun bathing. Totally natural." She spread it all over my cock, jerking me off with it until I was completely hard.
Then straddling her tall fit body over mine, she reached back and aimed me at…
Yep, right in her asshole. I'd never had anal sex before, so I had no idea how tight it would be. It was like having my cock grabbed by red-hot lava. Ever so slowly, Tay lowered herself until every inch of my cock was in her ass. "Ahh, we'll have to wait a bit for me to get used to you back there. I don't do anal very often," she explained.
I had no complaints. Even without moving it felt like heaven. I could feel her heartbeat with my cock. Her ass throbbed and rippled as she tried to accustom herself to the intrusion. Every so often, it would grip me HARD as she winced and gasped. After a while though, her sphincter started to relax and the tight head-to-shaft gripping would ease off.
"I think we could…" she said, rocking forward to pull almost off of me. Then she sat back down quickly, plunging me back inside of her. "Yeah," she confirmed, "that's perfect. Don't move- let me do this at my pace, OK?"
I nodded, perfectly happy to be her anal fuck toy. She started slowly, going up and down the full length of my cock. I reached up and pinched her nipples- "yes! harder" she said, obviously approving. Pretty soon, she was riding me faster and faster, alternating deep short fast strokes with long, deep, luxuriously slow strokes. Every so often, she'd plunge me up to the very hilt and stop, shuddering as a wave of pleasure broke over her. I counted fifteen full-on orgasms and dozens of mini-gasms.
Finally, she looked at me with those piercing blue eyes and said "now I want your cum inside of me." Abandoning any shred of control, I pulled her hips down and started thrusting into her. I didn't even attempt to be gentle. I just pounded her ass as hard and deep as I could. When I came, my cock was further inside of her than I thought it was possible to be. I held her down, mercilessly, as I shot wad after wad of hot cum inside of her.
After I came, Tay sat back with my cock still in her ass, and smiled. And then she surprised me even more by starting to talk about herself, why she became a researcher (she was studying a certain class of bark beetles that was costing forestry companies billions of dollars every year), why she loved the outdoors, what her family was like. It must have gone on for half an hour- I think we both actually forgot that my cock was still buried in her ass.
But eventually, we "unplugged" ourselves and went back into the stream to clean up. We held hands as we walked, naked, back to our camp and slept curled up together.
We didn't do anal again that trip, but we did eat each other out quite a bit. Tay was pretty good at giving head, and what I lacked in talent for eating pussy I more than made up with enthusiasm. The fun came to an end when we were finally assigned a third person a couple of weeks later. But we hooked up during the company end-of-season party in NYC and spent the entire weekend in bed- this time with plenty of condoms and much better beer.
