This is what I wrote to her:

I imagine inviting you for a hike or a walk in nature. Get a little off the beaten path and kiss and pet a little while, feeling our desire build. Out of sight of the path, but still at risk of being caught, I pull down your bottoms, with you leaning against a tree, and spread your pussy lips apart to expose your clit...licking slowly at first, lightly, then more firmly and faster, starting to suck your clit into my mouth here and there, slide a finger and then two into your wet pussy, and rhythmically slide them in and out of your pussy, pumping slowly and revving up, deeper with each pump...now I am devouring your clit, it has swollen up and is so responsive to my tongue and sucking lips. You hold on to the tree to steady yourself as you are nearing climax. I can feel you are right on the edge so I continue, increasing intensity knowing I will take you over the edge soon. You moan and yell and grab the back of my head and pull my face deeper into your pussy and you cum....your pussy juices change taste and texture and run freely, your body twitches as you feel each last wave as the orgasm tapers off. I lick you gently, helping you come down from it until you're still. I lick up as much of you as I can before standing back up and helping you pull up your bottoms...we hear someone coming...walk back out on to the path with mischievous little grins on our faces.

Her response:

We walk to the next offshoot on the trail and venture up it only a few yards. We can hear others walking on the main trail wth their bear bells clinking. Our mouths join and your tongue darts into my mouth. I can taste my pussy on you which drives me crazy. We kiss deeply as I expose one of your breasts and slightly brush your erect nipple. My hand rubs your mount firmly to feel your wetness through those tight shorts. I pull away from your mouth as you lean back on a huge boulder and take your nipple in my mouth gently, feeling it tighten. My hand has found your warm hood under your shorts and I'm brushing your clit tip as it swells, sucking on your nipple harder as I pull down your shorts. I slowly part yours lips. I cant resist anymore and go down on my knees to taste you.
You begin to pump your hips so I stick my tongue out as far as I can and use it to fuck that sweet pussy. My hand now rubs that stiff clit harder. You lift a leg to allow me in further as you squirt your passion juices on my tongue. I lap it up like a kitten drinking milk. I help you dress as more hikers are coming up our trail...they pass and say good morning. We both nod as it sure is...
