Sissy's Trainer Reveals Her Sheer 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.”

Alex’s eyes blazed with dominance. He unzipped slowly, freeing his thick, veiny 9-inch cock—rock-hard, pre-cum beading at the tip. “Beg for it, sissy. Prove you’re mine.”

“Please, Trainer Alex,” I whined, voice thick with need. “Train your sissy’s mouth. Fuck my face. I’m your slut in sheer stockings.”

He didn’t hesitate. Gripping my hair, he fed his cock past my glossy lips, stretching my mouth wide. I moaned around him, tongue swirling the salty head, tasting his musk. He thrust deep, hitting my throat, making me gag wetly but eagerly. “That’s it, deepthroat your trainer. Good girl—those stockings make you such a perfect cocksucker.” His hips pumped steadily, balls slapping my chin, saliva dripping down my chin onto my bra. I hollowed my cheeks, sucking like a vacuum, eyes watering up at him in submission. The mirrors reflected it all: me on my knees, sheer legs splayed, worshipping his dominance.

Minutes blurred into a sloppy, rhythmic face-fuck, his grunts filling the room. “Enough warm-up,” he growled, pulling out with a pop, strings of spit connecting us. “Bend over the bench, sissy. Time for real anal training.”

I scrambled up, heart hammering, and draped myself over the padded gym bench, ass high, stockings taut. Alex kicked my feet apart, admiring the view—my plugged hole winking under the garter straps, caged clitty leaking. He tugged the plug free with a slick pop, then lubed his cock generously, teasing my rim. “Beg for your trainer’s cock in that sissy pussy.”

“Fuck me, Sir! Train my ass hard!” I cried, pushing back.

He slammed in—thick, relentless, stretching my tight hole to its limits. I screamed in ecstasy, the burn turning to bliss as he bottomed out, balls-deep. “Fuck, you’re tight. Perfect sissy hole for my cock.” He set a brutal pace, doggy-style pounding, one hand spanking my stocking-clad ass—sharp cracks echoing, leaving red handprints blooming under the sheer nylon. “Stroke that caged clitty, slut. Feel how owned you are.”

I obeyed, fingers flying over the cage, the vibrations sending shocks through me as he railed me. His free hand yanked my hair, arching my back. “You’re my perfect sissy trainee—stockings, cage, greedy ass. Say it.”

“I’m your perfect sissy trainee!” I gasped, each thrust jolting me forward, tits bouncing. Spanks rained down, the sting making my hole clench around him. Sweat slicked our bodies, the room reeking of sex and nylon. He varied it—slow grinds circling my prostate, then jackhammering deep, his muscular hips slapping my cheeks. “Harder, Sir! Spank your sissy’s ass!”

Praises poured from him: “Such a good girl, taking every inch. These sheer stockings were made for this—legs spread for cock.” My clitty throbbed uselessly, pre-cum puddling on the bench. Orgasm built, anal-only, his girth milking me from inside.

“I’m close—gonna fill your sissy ass,” he roared.

“Yes! Breed me, Trainer!” I begged, stroking frantically.

With a guttural groan, Alex buried deep, cock pulsing as hot cum flooded my guts—rope after thick rope, marking me. The sensation shattered me; even caged, I came hands-free, clitty spurting weak jets onto the bench, body convulsing in waves of sissy bliss.

He pulled out slowly, cum leaking down my stockings, and spun me around. Kneeling again, I licked him clean, savoring our mixed flavors. Panting, he fished a key from his pocket—the one I’d confessed my cage combo to earlier—and unlocked me. My clitty sprang free, spent but twitching.

“Cum again if you can, princess,” he murmured, stroking it gently. Another weak spurt dribbled out, pure aftershocks.

Grinning, he produced a gift bag: new sheer stockings, even thinner, fishnet-trimmed. “Wear these tomorrow. Daily training sessions now—mouth, ass, full sissy submission. You’re addicted, aren’t you?”

“Yes, Sir,” I breathed, newly exposed identity blooming inside me. “I’m your sissy forever.”

We cuddled on the mat, his strong arms around me, planning my transformation—heels next session, maybe makeup. I felt complete, owned, eager for more.

Then, the door burst open.

“Sissy? Oh my god, what the hell is this?!”

My roommate, Mia—blonde, nosy, and way too invested in my secrets—stood frozen in the doorway, eyes wide at the cum-streaked scene, my torn stockings, Alex’s softening cock still glistening.
