We could rent a car and drive to the mountains in the spring, and find a quiet, uninhabited trail in the Cascades. You could drive and I could keep you entertained on the way up the beautiful tree-lined mountain roads by gently stroking your growing cock, being careful not to get you too aroused so you could focus on the car. I'd lean over and kiss you behind your ear, gently nibbling at your ear lobe, keeping one hand moving back and forth against your now hard cock, stroking it to full attention...
You'd struggle to park, but make it to the trail head safely, begging me to suck you off in the parking lot.
"Not yet," I'd say, "there are too many people around."
"But they don't seem to be paying attention to us," you'd whisper in my ear while beginning to rub my pussy through my now damp jeans. Your gentle rubbing against me, coupled with the strangers milling around in the parking lot behind us, threatening to take a peek, would turn me on enough to not be able to turn down your huge hard cock.
"Mmm...just for a moment," I'd gently moan, lowering my lips around your throbbing head. Licking it just around the tip...Licking down the shaft, with my hands fondling your balls, then back to the head, licking, opening my mouth just a bit wider...
Sucking it ever so slowly and deeply, moving my head up and down the shaft, keeping my tongue encircled around the tip.
I'd continue alternating sucking up and down your shaft, pausing to lick at your balls...
Another car pulls up next to us.
"Damn, I guess we'd better stop this for now," I'd say, with a touch of animosity towards the people arriving next to us.
So we gather our backpacks and head up the trail.
"But it's so hard to walk like this; we have to do something about it," you'd say while caressing my neck.
I'd respond, "I know, but there are so many people around!"
I'd pull out the topographical map and find a short offshoot of the trail up ahead, just a tad steeper than the one we're on. "I have an idea..." I'd say, while leading you off to the other trail, with you following close behind me, trying to, but not successfully, take your eyes off my ass, so as not to grow your cock even bigger.
We continue walking for awhile until we see that we're finally in privacy. You lean up against a tree and unzip your pants.
"How about now?" you ask.
"Hmm... I suppose...," I coo back at you, while lowering my lips onto your huge trembling cock. "Mmmm..." I moan with complete satisfaction at the length of your cock filling my mouth. I'd suck at the tip at first, then engulf all of your huge penis into my mouth, feeling your precum in the back of my mouth. I'd steadily bob my head up and down on your penis, sucking while twirling my tongue all around it.You'd fondle my breasts and pull at my nipples, encouraging me to pick up speed.
"I think I hear someone coming," you'd tell me. Upon hearing that I'd start bobbing and sucking faster and faster, moaning with delight at the situation, and grabbing at your balls.
"Oh I'm getting close..." you'd say..."But those people are coming around the corner...Oh, damn, hurry..."
I'd quickly increase my speed and suck, and suck, and suck back and forth down your shaft and around your head, sucking until I feel the sweet sensation of your cum filling my mouth. I'd swallow it all, and then lick it clean, helping you zip your pants just in time for the hikers to hear me slide the zipper up your pants.
