Busty Office Lady Secretly Teases Nipples on Crowded Train

On a rainy evening during the rainy season, the commuter train was packed as usual. I, Hiroki, am a graphic designer, and today I was exhausted from being glued to my desk until late. In my early thirties, I'm the type who's content with this daily routine just continuing. I haven't had a girlfriend for years, and I hardly remember touching a woman's body. But I do enjoy imagining things. Especially when I see a woman with large breasts, I can't help but inflate erotic scenarios in my mind. That bad habit of mine showed itself on the train that day. The train swayed, and at the next station, the crowd thinned a bit. I finally managed to sit down. The woman who sat next to me was wearing a black blouse. Her name was Emi, apparently an office lady in HR. I found out later she was in her late twenties and heading home from work. But what caught my eye first was her chest. The blouse clung tightly, and her ample breasts, likely G-cup, swayed as if about to burst out. Due to the humidity of the rainy season, they seemed a bit sweaty, with the cleavage glistening. (Wow, way too big... If I touched those, my fingers would get buried.) I tried to look away, but it was impossible. With the train's movement, her large breasts lightly brushed against my arm. The soft sensation came through the fabric, and my crotch reacted immediately. Emi seemed to notice my gaze. She smiled slightly and secretly undid one button on her blouse. Then another. Now the cleavage was deeper, with a glimpse of her white bra. Her massive breasts pressed heavily against each other. The roundness of her breasts rose and fell with each breath. Amid the noise of the train, she whispered in my ear. "Are you interested in my breasts? Don't you want to touch them?" Her voice was sweet and damp like the sound of rain. I was startled and quickly looked around. No one noticed. It felt like we were alone in the shadow of the seats. (Is this for real... here? But I want to touch them. So badly.) With trembling hands, I reached out to her chest. Emi’s large breasts were softer than I imagined. My fingers sank in, warmth spreading through the blouse. She leaned closer, pressing her nipple against my hand. "It's getting hard here, isn't it? Touch it harder." At her words, my fingers moved naturally. I slipped my fingers into the gap of her bra, searching for her nipple. It was already plump and swollen, hard. I pinched it and rolled it gently. Emi let out a small breath. "Mmm... that's good, you're good at this." The weight of her large breasts rested on my hand, changing shape as I kneaded them. Her breast skin was smooth, with a faint scent of sweat drifting. (This is like a dream. Her nipples are sucking onto my fingers...) Every time the train swayed on a curve, her huge breasts bumped against my arm, and my excitement wouldn't stop. Emi became even bolder. She brought her lips to my ear, blowing hot breath. "Deeper. My nipples are sensitive, so make me come continuously." Make me come? Those words made my cock twitch in my pants. She lifted the hem of her blouse a bit herself and shifted her bra. Now I touched her bare large breasts directly. Her nipples were pink, trembling when I pinched them. I rolled them frantically. Rubbing the tips with my fingertips, sometimes lightly scratching with my nails. Emi’s body reacted with a twitch. "Ahh... there, that's good... faster." Her voice echoed in my ear, heating up my crotch. I cupped her entire large breasts with both hands and started kneading. The breast flesh overflowed between my fingers, the softness spreading like waves. Due to the steamy humidity of the rainy season, her skin was moist. (Her nipples are hot, as if squeezing my fingers. I can't believe it's this erotic.) Emi writhed, reaching her first climax. "Mmm... I'm coming..." Her large breasts trembled, nipples hardening further. But it didn't stop. Emi didn't let go of my hand; instead, she stroked my crotch with her own fingers. "You're excited too, aren't you? Let's play more with my breasts." Smiling, she pressed her nipples against my fingers to guide them. This time, I teased them in circles. I held the base of her nipples and pinched the tips. Emi’s breathing became ragged, and a second wave came. "Again... coming... your fingers are the best." Her large breasts glistened with sweat, my fingers sliding into the cleavage. The sensation was irresistible. The soft, pliant breasts enveloped my palms and wouldn't let go. The train's sway added to it, as if we were having sex. (My cock is erect to the point of pain. I want to bury myself in those breasts... forever.) Emi came continuously, third time, fourth time. Her body trembled finely, her whispers in my ear becoming sweeter. "Feeling this much... you're special." I just kept touching her large breasts greedily. Tracing even the wrinkles around her nipples with my fingers. I could only imagine how wet her pussy was, but it must be soaked now. The climax came when Emi wrapped her arms around my neck and kissed me. Her lips were soft, tongues intertwining. The taste of saliva was sweet and sour. All the while, my hands didn't stop teasing her nipples. Her large breasts pressed against my chest, making it hard to breathe. "Ahh... no more... that's the fifth time." Emi’s body shook greatly with the final climax. Her nipples pulsed in my fingers. The train arrived at the station, and the surroundings grew noisy, but we didn't notice. When I finally let go, Emi caught her breath with satisfaction. "Hehe, that was fun. Want to exchange contact info?" I nodded blankly and held out my phone. Emi entered her number and smiled. "Next time, let's take it slow and touch each other more. My big breasts are always waiting." Psychologically, we felt connected. It was sudden intimacy, but a relationship where we respect each other. That was the feeling. The train arrived at the next station, and Emi got off. I stayed in my seat, recalling the sensation of her nipples on my fingers. As the rainy season rain tapped the window, the throbbing in my crotch wouldn't subside. (Touching those huge breasts again... maybe my life will change.) Even now, every time I remember that evening train, the excitement returns. I'm looking forward to next time with Emi.
