The subway car jolted forward and I pressed my body into the wall of strangers like I belonged there. My cock was already half-hard beneath my jeans, the denim doing nothing to hide the slow, deliberate grind I planned. It was rush hour, bodies packed so tight that no one could tell whose hand was whose or whose thigh belonged to whom. I had chosen my spot carefully: directly behind a woman in a fitted pencil skirt, her ass round and firm, the fabric stretched smooth over each cheek. She clutched a strap overhead, earbuds in, eyes closed to the world. She would never know it was me.
I shifted my weight as the train swayed, letting my crotch brush against her. Just a whisper of contact at first, the rough seam of my jeans grazing the cleft of her ass. Heat bloomed through the thin layers between us. My breathing stayed even, but inside my chest my pulse hammered. I eased forward another inch, pressing the length of my erection more firmly against her. The softness of her flesh yielded, molding around me for a single suspended second before the train righted itself and I eased back like it was nothing.
She didnt flinch. That was the rush. The knowledge that I could take this small, filthy liberty and she would remain unaware, or at least unwilling to cause a scene. I waited for the next lurch, timed it perfectly, and ground harder. My cock throbbed, trapped at an awkward angle, the head catching against the curve of her ass. I felt the give of her body, the way her skirt slid a fraction of an inch under the pressure. Pre-cum had already begun to soak into my underwear, making everything slicker, more obscene.
The train slowed into the next station and more people crammed in. I used the fresh surge of bodies to justify another shift, this time angling my hips so my shaft slid along the cleft of her ass in a slow, deliberate drag. The friction sent sparks up my spine. I could smell her perfume now, something floral and clean that mixed with the metallic tang of the subway and the faint musk of sweat. My free hand hung at my side, fingers twitching with the urge to reach around and cup her, but that would break the rules Id set for myself. This was about the rub, the secret pressure, the stolen heat.
When the doors closed again, I leaned in once more. This time I let my balls press against her too, heavy and aching. The full weight of my arousal rested against her for three long seconds while the train accelerated. I felt her shift slightly, maybe adjusting her stance, and the movement dragged her ass across my cock in a way that nearly made me groan aloud. I bit the inside of my cheek instead, tasting copper. My orgasm was building already, slow and inevitable, fed by the constant, maddening friction and the knowledge that dozens of people stood inches away, oblivious.
I kept the rhythm subtle, matching the natural sway of the car. Forward when it braked, back when it accelerated, each movement calculated to maximize the slide of my cock against her.
The fabric between us grew damp from my leaking cock, the wet spot spreading. I imagined her feeling the warmth, wondering if it was just the crowded heat or something more. The thought made me throb harder. I pressed again, firmer this time, letting the head of my cock nudge right where her cheeks parted. The skirt was thin enough that I could almost feel the cleft itself.
Another station came and went. She still hadnt moved away. Maybe she liked the pressure and thought it was accidental. Maybe she knew and didnt care. Either possibility sent another pulse of blood to my cock. I was close now, the constant grinding pushing me toward the edge with ruthless efficiency. My balls tightened. I risked one more long, slow drag, hips rolling in a tiny circle that no one but me would notice. The friction peaked, perfect and filthy, and I came with a silent shudder, flooding my underwear in hot, pulsing spurts. My cock jerked against her ass with each contraction, the wet heat trapped between us.
I stayed pressed there until the last tremor faded, then eased back as the train slowed for my stop. She never turned around. I stepped off onto the platform, the sticky mess cooling against my skin, already planning tomorrows ride. The confession sat heavy and sweet in my chest: I had taken what I wanted in plain sight, and the world had let me.
