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 β 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.
