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.”

Alex’s grin widened, wicked and knowing. “Stockings? Fuck, that’s hot. Show me later. For now, let’s stretch you out. Private session means we go deep.” He guided me to the mat, his big hands on my waist, adjusting my stance. Every touch sparked electricity, his fingers brushing my hips, making me squirm. Tension built with every pose—downward dog had my shorts riding up dangerously close to exposing the lace, his eyes devouring me from behind. “Good girl. Arch that back more. Yeah, just like that.”

By the time we moved to assisted stretches, I was a blushing mess, nipples hard under my tank, clitty dripping pre-cum into its cage. He had me on my back, legs up in a straddle, his muscular body pressing between them to deepen the pull. That’s when it happened—my shorts hiked up, and there they were: the sheer black stockings peeking out, glossy nylon shimmering under the gym lights, hugging my toned calves and thighs like liquid silk.

Alex froze, his hands gripping my ankles. “Holy shit, Sissy. Look at those legs.” His voice dropped to a husky growl, eyes darkening with lust as he ran a single finger along the sheer fabric, from my ankle up to the lacy top. “So smooth, so fucking sexy. Sheer black stockings on a shy little trans girl like you? You’re full of surprises.”

I whimpered, thighs trembling under his touch. “Alex... I didn’t mean for you to see. They’re my secret. Make me feel like a real girl.”

He didn’t pull away. Instead, he slid his hands higher, caressing the glossy nylon, thumbs tracing the garter clips hidden beneath. “Secret’s out now, princess. Stand up. Model them for me. Show your trainer what a good sissy you are.”

The command in his voice melted me. Consensually, eagerly, I rose on shaky legs, turning slowly in the mirrors. I peeled off my tank top first, revealing my perky B-cup tits in a lacy bra, then hooked my thumbs in my shorts, shimmying them down inch by inch. The stockings gleamed—ultra-sheer, 20-denier black nylon, flawless on my shaved legs, the garter belt framing my caged clitty in pink plastic, already glistening with need.

“Fuck, look at you,” Alex groaned, stepping behind me, his bulge pressing against my ass through his pants. His hands roamed freely now, squeezing my stocking-clad thighs, snapping the garters. “These legs were made for this. Smooth as silk, begging to be wrapped around me. You’re not just training your body—you’re training to be my sissy slut, aren’t you?”

I nodded, spinning to face him, eyes locked on the massive tent in his cargos. “Yes, Sir. Please... train me. I’ve dreamed of a dominant man like you exposing me.” The words spilled out, confessional and desperate. My knees buckled, and I dropped to them right there on the gym mat, hands on his thighs. “Use me. Let me worship that bulging cock.”

I tugged his zipper down with trembling fingers, freeing the thick, veined cock that sprang free, already rock-hard and leaking a bead of precum from the fat head. It was huge—easily nine inches, girthy enough that my fingers didn’t quite meet as I wrapped both hands around the shaft and leaned in, licking that salty drop like the desperate sissy I was. Alex groaned low, fisting a hand in my hair as I opened wide and took him into my mouth, lips stretching around the heat of him. I bobbed eagerly, tongue swirling under the glans, sucking sloppy and loud while my caged clitty throbbed uselessly in its pink prison, dripping onto the mat between my stocking-clad knees.

“That’s it, good girl,” he growled, hips rocking forward to fuck my throat deeper. “Worship that cock like the stocking slut you are. Look at those sheer legs trembling while you choke on me.” I moaned around him, the vibration making his balls tighten against my chin. Spit slicked my chin as I worked him, one hand stroking what I couldn’t swallow, the other cupping his heavy sack. He pulled free with a wet pop, a string of drool connecting my lips to his tip, and hauled me up by the arms.

Alex spun me toward the mirrored wall, bending me over a padded bench so my ass presented high. He yanked my lacy panties aside—what little scrap they were—and spat on my tight pink hole, rubbing the wetness in with two thick fingers. “You want your trainer stretching this pretty sissy cunt? Beg for it.”

“Please, Alex—Sir—fuck my ass, train me open,” I whimpered, pushing back onto his fingers as he worked a third inside, scissoring me loose. The stretch burned sweet, my stockings whispering as I shifted my weight, garters snapping against my thighs. He lined up that massive cock, the blunt head kissing my rim, and pushed in steady and deep. I cried out in pure pleasure as he bottomed out, balls flush against me, filling me so completely my eyes watered. He held still, letting me adjust, hands roaming the glossy nylon on my legs like he couldn’t get enough.

Then he started thrusting—long, powerful strokes that rocked me forward, each one dragging over my prostate until my locked clitty leaked steadily into the cage. “Fuck, so tight and hot,” he snarled, slapping my ass hard enough to sting. “Taking trainer cock like you were born for it. These stockings make you look like such a perfect little whore.” I watched us in the mirror: my B-cups bouncing in the bra, his muscular body slamming into my soft curves, sheer black nylon gleaming under the lights with every slap of skin.

He reached around, teasing my nipples through the lace while pounding harder, faster, the wet sounds of my stretched hole filling the private room. “Come for me without touching that locked clit—clench and squirt for your Sir.” The command wrecked me. Pleasure coiled tight and exploded; my ass spasmed around his cock as I came hard, clear fluid spurting from the tip of my cage in messy pulses, soaking the bench and my thighs. I sobbed his name, legs shaking in the stockings, body milking him ruthlessly.

Alex cursed, slamming deep one last time as his cock pulsed, flooding my guts with thick ropes of cum. He kept thrusting through it, packing every drop inside until it leaked out around his shaft in creamy rivulets down my stockings. When he finally pulled free, a gush followed, and he pushed it back in with his fingers, claiming me.

We collapsed together on the mat after, me curled against his chest still in my sheer black stockings and open cage, both of us catching our breath. He kissed my forehead, voice rough but fond. “Next session we go longer. Bring the pink cage and those stockings again—my sissy needs regular anal training.” I smiled up at him, blissed out and already aching for more, knowing I’d never hide under baggy clothes again.
