At the station in front of the train platform, I met a girl fiddling with her smartphone as usual. Her cute and innocent demeanor caught my eye, along with her voluptuous lower body and large breasts clearly visible even through her clothes. When she bent forward slightly to organize her luggage, I got the idea to secretly film her from a distance. I couldn't tell if her panties were just hidden or if she wasn't wearing any at all—either way, my heart started racing. I followed her to the platform and got on the same train as usual, ready to start teasing her again. Gently lifting her skirt, I was shocked to find she was wearing a thong! The sight of her plump lower body became even more prominent—she looked like such a naughty girl, incredibly erotic. I shifted my attention upward, but she protested with a soft "Hey... stop it." With no choice, I flipped her skirt up and touched her thick, round ass—its firm yet soft elasticity felt so good I couldn't help myself. Next, I moved to her magnificent big tits. Unbuttoning her blouse, I exposed her nipples, finding her breasts as huge and sensitive as I'd imagined. I pulled out a vibrator and pressed it against her pussy through her panties, feeling her body twitch with arousal. When I slipped the vibrator inside her panties, she begged in a sexy voice, "Please take it out..."—so damn cute and erotic. Her face started to glaze over, clearly turned on. Pressing the vibrator deeper, she began grinding her hips erotically, unable to resist. The way she tried so hard to hold back made her seem even more adorably slutty. Then I guided her soft, small hand to grip my cock and stroke it—her gentle handjob felt unbelievably erotic. When I started grinding the vibrator deeper, she moved her hips in sync and quietly climaxed. Riding that momentum, I groped her full ass while pulling her panties down and pressed the vibrator directly against her bare pussy. Her body jerked violently as she came again. I then started fingering her pussy, eventually making her squirt completely. Her huge tits and sensitive nipples drove me wild. As usual, I made her get off the train midway and headed to the restroom. I quietly undressed her—now obedient—and teased her tits and nipples while she writhed, weakly pleading, "Stop... please..." even though it was too late. I had her sit on a luggage shelf and resumed the vibrator assault, making her climax once more. Without a word, I smoothly slid my cock inside her bare pussy. She moaned loudly the moment I entered—so damn cute. "Stop... pull out..." she begged, yet again in that irresistibly sexy voice. But her tight, plump pussy felt so amazing, I couldn't stop. Even as she kept begging, "Pull out..." I found her cuteness overwhelming. Next, I switched to doggy style. Her ass cheeks squeezed around me, tightening even more—feeling so good I couldn't hold back. With lewd slapping sounds filling the air, I asked if I could cum inside. "No... stop..." she pleaded in a sweet voice. Yet she kept whispering, "Don't cum... stop..."—so damn erotic and adorable I couldn't possibly resist. Hearing her beg like that, I lost control and shot my load deep inside her. When she whispered, "Did you... cum?" I found her so cute I couldn't help but smile. I quickly watched her dress and then waved goodbye as I left.
