I lost track of how long I was tied up at the summit.
The sun was warm against my exposed skin, and the wind occasionally swept through the bushes, giving me fleeting moments of cool air across my bound and spread ass. The jacket was gone. Amber must have taken it with her when she "left." All that remained on my body was the pink tutu lifted up around my waist, exposing everything.
I could hear hikers passing in the distance, some closer than others. I didn't know how visible I was, but the thrill of not knowing, that mix of humiliation, anticipation, and deep submission, had me dripping from my cage within minutes.
Then I heard the soft crunch of footsteps on the gravel path behind me.
Amber's voice came through the speaker of her streaming phone, now mounted discreetly nearby.
"Looks like we have our first visitor, stream. Be polite, SISSY."
I braced myself.
A woman stepped into view. Mid-30s, toned, wearing tight running shorts and a tank top. Her hair was tied back, and she had a look of mischief in her eyes. She didn't say a word. She simply walked over to the harnesses Amber had left beside me, picked out the biggest strap-on, and slid it on like she'd done it a hundred times before.
The dildo she chose curved upward, perfect for grinding into my prostate. She lubed it generously, gave my ass a light slap, then lined herself up.
I let out a muffled moan through the O-ring gag as she slid in with one smooth stroke.
She started slow, rocking her hips as if we were lovers. But I knew what this was. I was her toy, her public use SISSY, and she knew it. Her rhythm picked up, and with every thrust, the dildo inside me pushed hard against my prostate. My cage strained. I drooled helplessly from the gag.
She reached underneath me and rubbed two fingers up my taint, teasing the base of my cage and the tattooed QR code on my gooch.
Another moan escaped me, louder this time.
When she came, grinding down hard and shuddering, she let out a sharp exhale, pulled out slowly, then leaned forward and whispered, "You're the best little bitch I've ever fucked."
She left without another word, disappearing into the woods like she had only stopped for water.
A few minutes passed. I was still trembling, breath hitching, ass twitching open and trying to grip something that wasn't there.
Then the stream's speaker crackled to life again.
"$62,000 raised and counting. You're a hit, Cade."
Amber's voice.
"Let's see if we can hit $100k today. Don't worry, I've invited a few more 'guests' to keep you company."
Just then, I heard more footsteps.
