We were back at the family home, spending not quite a full week with our parents.
At least, that was how we justified it to them in making our travel plans.
We were home for a few days. The best my big brother and I could muster were a few stolen moments here and there, my favorite being the morning when, with our parents both in the kitchen fixing breakfast, my forbidden lover entered my bedroom, pinned my body to the wall beside the open bedroom door, and humped me as he molested my willing body and swallowed my joyous whimpers.
Fortunately, our parents both recognized just how much my big brother and I wanted to return to our favorite camping spot in the mountains, and graciously allowed us to go spend two days there. I had not expected they would allow it, as we were only visiting our parents for such a relatively short time, returning to California on a Friday so that my big brother and I could both return to our jobs on Saturday.
As my fraternal twin finished packing the truck on a Tuesday afternoon, my mother caught me packing in my bedroom and gave me some advice:
"Scream for him, loudly," she said with a wink and a grin. "He will really love that!!!"
I blushed, profusely. Receiving sex advice from my own mother was incredibly awkward at best, even though she both knew about and definitely approved of the forbidden relationship. But at least I still had one key secret: She did not know that my fraternal twin was also my Master.
When I finally slid into the truck and sat beside my Master once again, I was full of excitement. My body was practically vibrating with anticipation of our campout and of the illicit adventures we would have.
And, just as importantly to me, I was looking forward to screaming for him – screaming of my love and my pain for his enjoyment, screaming loud enough to scare away any animals who might be in the area, screaming until I practically lost my voice and did not need a gag to be muted.
"You're grinning, baby sister," he noted as he started the engine. "Is there something I should know about?"
"Just looking forward to truly letting go," I admitted, quite aware of the smile upon my face, "unleashing my voice and screaming for you again and again."
"Hmmm... I think I'd like that!"
We laughed together for a moment, then began the journey toward our favorite camping spot.
Once we were out of town, my domination began.
"Off with the shorts and the thong," my Master commanded. That did not bother me much at all, as no one would be able to see me below the rib cage unless they were in a passing semi. I slipped off my sandals and began to undress as ordered, leaving the shorts and the thong between us on the bench seat.
I looked at my Master and saw his smile as his eyes glanced over me and confirmed my compliance.
"Do you like what you see, Master?" I asked in my best possible "innocent little girl" voice, smiling sweetly and batting my eyes.
"Definitely," he replied, quickly returning his eyes to the pavement before us. "Now, I want you to make yourself wet."
I maneuvered to lean in the corner created by the door and the back of the seat, my hair being whipped around my face by the wind. A slight concern passed through my mind at doing such naughty things in public, but no one but my big brother and Master could see anything which society dictates must always be hidden from view, so I took a deep breath, closed my eyes, and began to finger myself.
By the time we arrived at the base of the mountain, I had brought myself to the brink of orgasm at least six times, but had disappointedly obeyed my Master's commands and denied myself the release I so desperately craved. It was actually a letdown to don the thong and shorts once more, and that emotion surprised me greatly.
Perhaps I had a deep-hidden desire to be discovered in a compromising position by strangers. Perhaps I was an exhibitionist at heart.

The campsite set up, the dinner dishes washed and put away, the bear bag hung, I straddled my Master as I massaged his bare back. We each wore only our swimwear, but I had a strong feeling that even that scant clothing would be shed before nightfall.
Movement at the edge of my peripheral vision caught my attention, and I slowly turned my head to see a deer, a doe, slowly approaching the stream. She kept an eye on us as she moved cautiously, remaining alert, vigilant. "Deer to your right," I whispered, and my Master slowly turned his head in that direction.
In a way, it felt like the calm before the storm. We both watched with interest as the doe made her way to the stream, dipped her head, and began to drink. My hands never stopped their work, functioning on auto-pilot as my attention was focused upon the wary creature gracing us with her presence. I wondered if she would return later, if our choice of campsite violated her sense of territory, if she would flee the state once my Master made me scream for him.

My ass was truly aflame, certainly impressively marked by the thin branch my Master wielded. Tears cascaded down my face, and rough tree bark scratched at my arms and the front of my naked body, for I was secured to the tree with rope linking the D-rings on the wrist cuffs and ensuring that I was continually hugging the tree.
"I will not stop until you scream for me," he had threatened with his kind, soothing voice.
I had lost count of how many strikes I had already endured from the thin branch. Ultimately, it did not matter. Either the fiery pain would become so unbearable that I used my safeword, or I would essentially admit defeat and scream loud and long for him.
As it was, my body was shuddering almost violently in the aftermath of each bite of the thin branch. Each strike added a new line of searing pain to my existence, causing me to grunt loudly through gritted teeth. Even without the bonds, I would almost certainly have been hugging the tree tightly, somehow drawing a meager ray of comfort from its steady strength.
Watching the doe had been the calm; this was indeed the storm. My tears fell unabated, my heart thundered rapidly, my breathing was rapid and shallow, and I struggled in my bonds even as I firmly held the trunk before me.
More than anything else, this was a test. My Master was specifically testing my limit with this branch – he had said so before starting to hurt me. Yet, although this was simply a test, the level of pain was unlike anything I had felt before, giving the scene the semblance of a harsh punishment.
Mentally, I was in turmoil. I could not decide if I could endure any more, yet I did not want to give in and admit defeat, whether via safeword or via scream.
But then, suddenly, I felt as if I was floating. My body felt detached from my mind. The pain did not seem so bad, and seemed to actually be lessening even though I could still feel the bites of the branch...
And then, I was laying upon my Master, his hands caressing my sweat-dampened back as a gentle cool breeze wafted over us. My ass still felt ablaze, and I was sniffling between whimpers into his neck. Nighttime enveloped us completely, with only the small campfire providing any light, and even the flames had nearly regressed into smoldering coals.
It took some time for me to find the strength to lift myself up on my arms and gaze upon the loving face of my big brother and Master. His expression was one of concern laced with desire, and I felt a telltale solidification and lengthening beneath me.
