I couldn't help but get captivated the moment I spotted a voluptuous girl with bare legs, looking lonely while fiddling with her smartphone. I tried sneaking a panty shot by following her onto an escalator, but failed—so I boldly boarded the same train and started touching her. First, I slowly lifted her skirt and caressed her thighs, but she tightly guarded herself with her hands. Undeterred, I moved in front and reached for her breasts, only to be protested with "Stop it, please." With no choice, I shifted focus to her lower body. As I played with her plump thighs and pussy, her body began trembling slightly, clearly showing signs of arousal. I brought out a vibrator and attacked her, again met with "Stop it" and "I don't want this," but I ignored her and shoved the vibrator right into her panties. Her body twitched violently, exuding a filthy, erotic vibe. Her expression gradually turned submissive, driving me wild with excitement. I unbuttoned her blouse and groped her tits—she was a big-titted girl, and her plump nipples peeking through her bra were insanely sexy. I pulled her close, kneading her soft ass, then forcefully yanked her panties down into a thong. Rubbing my cock against her while teasing her nipples became one of the hottest moments. Ignoring her continued pleas of "Stop it," I forced her to grab my cock and jerk me off while I kept vibrating her. Next, I clamped the vibrator against her pussy and stimulated her nipples at the same time. After roughly stripping her panties off completely, she shyly closed her legs—her embarrassment turned me on like crazy. Gently playing with her bare pussy, I heard her moans of pleasure, accompanied by wet, squishy sounds from her slit. Then, just like a whale spouting water, she squirted—and I couldn't hold back, making a sudden stop to rush into a restroom. I pressed the voluptuous girl against the wall from behind, fondling her all over, made her take off her sweater herself, and attacked her again with the vibrator. Her frightened expression, mixed with clear arousal, was absolutely irresistible. Even as she protested, she kept rubbing my cock, getting me fully primed. I made her place her hands on the sink and forcefully took her from behind, bareback. The moment I entered, I felt her thick, juicy ass cheeks tightly hugging my cock. The soft, fluffy feel of her big tits in my hands was unreal. With every thrust, her massive breasts bounced wildly, amplifying the eroticism. She was truly an obscenely hot girl. My thrusts grew more intense, and as I told her I was about to cum, she cried "No... no..." while remaining completely passive—allowing me to creampie her fully. She snapped out of it slightly, tossing the cum-covered tissue into the toilet in a huff—her pissed-off look was unbelievably sexy. Then she quickly fixed her clothes, got ready to leave, and quietly said goodbye before walking away.
