MGOLD-053 Kuroi-san, my classmate who secretly lets me cum inside her while we're commuting by train - Live-action adaptation of the popular comic with over 100,000 copies sold!

[Super popular author Hiyashimakura x FALENO's first collaboration!!] Every morning, I commute to school on a crowded train that takes an hour each way. One day, I get swept away in the crowd and end up pressed against a classmate, Kuroi Seina. I accidentally touch her butt, and it's so soft that I can't help but squeeze it. Then my erection touches her and she notices. I brace myself for social ruin, but what Kuroi said was... "You can come inside me."
