Caught by uncle

I had been cursed for as long as I could remember, each time I reached the pinnacle of my pleasure, the world around me seemed to grow, and my body shrank in response. It was a condition that had to be kept hidden at all costs. My lust for other men, combined with my uncontrollable size shifts, made for a dangerous combination. For six days, I had managed to restrain myself, sharing a bed with my uncle at the family reunion. We had grown close over the years, and he was one of the few people I trusted to keep my secret. But the urge was too much to bear, and I claimed to not feeling well, staying behind as everyone left for a movie. I didn't waste any time, my fingers finding their way to my cock, and the familiar dizziness began to wash over me. The world around me seemed to expand, and I could feel my body shrinking. It usually took an hour or two for the regrowth, but this time, it seemed to be taking much longer. My heart raced, and I could hear the distant slamming of car doors. Panic set in, and I barely managed to close the images on my laptop before the doorknob turned. I scurried behind the screen just as my uncle entered and sat down on the bed. "Pete?" He called out as he noticed the explicit images on my screen, chuckling darkly. "Hah, the horny fucker forgot to lock his screen." I held my breath, hidden behind the laptop screen. The door shut, and I heard the unbuckling of his belt. My heart raced as he lay down beside me, his cock inches away from my tiny form. The musky scent of his arousal filled the air. I couldn't help but steal a peek around the corner of the screen, and it was then that I saw his gaze resting on me. I braced myself for his anger, but instead, the grin on his face grew wider, and he reached out, gripping me between his palm and his throbbing cock. The sight of my small, helpless form seemed to excite him further, and he began to stroke himself. I couldn't believe how much I enjoyed the sensation of his rough palm and his cock's heat enveloping me. As he continued to pleasure himself, he spoke in hushed tones, "You've been keeping this a secret for a while, haven't you, Pete?" His voice was filled with a mix of shock and excitement. I could only nod, feeling both terrified and thrilled to have finally been discovered. My uncle's cock pulsed, and I could feel the warmth of his precum coating my tiny frame. He leaned in closer, his breath hot on my skin as he whispered, "You know what happens now, don't you?" I shook my head, too afraid to speak. "You belong to me now, Pete. You'll be my pet." I had never felt so small or so desired at the same time. My uncle's cock twitched again, and I realized that there was no going back. I was his to pleasure, at his mercy, and my body trembled with arousal.
