[I hurriedly boarded a train car only to find it was a women-only car!] At the last moment before departure, I rushed onto the train, only to realize it was the women-only car! I quickly took a seat, surrounded by numerous women whose presence immediately caught my eye. With occasional upskirt and cleavage views flashing by, I couldn't help it—my cock steadily grew erect. The woman sitting next to me noticed, and I panicked, trying to hide it, but my erection refused to subside, so I secretly touched it. My actions caught the attention of nearby passengers, putting me in serious trouble! My cock was stared at openly from all around, and I was labeled a pervert. A strange mix of shame and excitement overwhelmed me! *Note: This work does not contain any sex scenes.*
