Trainer Exposes Sissy Stocking Secret

I’ve always been shy, the kind of girl who hides in baggy gym shorts and oversized tees, even though my body screams for something prettier. At 20, I’d finally mustered the courage to book a personal training session at this upscale gym downtown, hoping to tone up my soft curves without drawing too much attention. My name’s Sissy—yeah, I chose it myself after years of secret dressing—and today was my first one-on-one with Alex, the trainer everyone raved about online. Muscular, 28, with that confident smirk in his profile pic that made my caged clitty twitch just looking at it. I’d locked myself up that morning, a pretty pink chastity cage hugging my little girlcock, because fantasies like this always got me leaking.

I arrived early, heart pounding as I changed in the private locker room. Under my loose black gym shorts and tank top, I’d slipped on my secret indulgence: sheer black stockings, the kind that clung to my smooth-shaven legs like a second skin, whisper-thin and glossy, ending mid-thigh with a lacy garter band I’d hidden under the hem. They made me feel so feminine, so slutty, but I tugged the shorts down extra low to cover them. No one would know. I was just here to work out, right?

Alex was waiting in the mirrored training room when I timidly pushed open the door. God, he was even hotter in person—six-foot-two of ripped muscle, broad shoulders straining his tight trainer’s polo, cargo pants hugging powerful thighs. His dark hair was cropped short, and those piercing green eyes locked onto me immediately, sizing me up with a predatory grin.

“Hey, Sissy, right? First session—let’s make it count.” His voice was deep, commanding, sending shivers up my stocking-clad legs. He shook my hand, his grip firm, lingering just a second too long. “You look... tense. Those clothes are swallowing you whole. Hiding something under there?”

I blushed crimson, stammering as I dropped my gym bag. “N-no, just... comfortable. I’m shy about my body.” My voice came out higher than I meant, all breathy and girly. He circled me like a wolf, eyes trailing over my ill-fitting outfit.

“Comfortable? Nah, that’s not it. You’ve got curves begging to be shown off—those hips, that ass. Why bury them?” He stepped closer, his cologne musky and intoxicating. I could feel heat rising in my cheeks, my clitty straining uselessly against its cage. “Admit it, Sissy. You’re hiding your feminine side. Something pretty under those baggy shorts, huh?”

My heart raced. How did he know? I fidgeted, the stockings whispering against my thighs. “I... maybe. I like feeling girly sometimes. Sheer stockings. They make my legs look smooth and sexy, but I didn’t think anyone would notice.”
