[Kurodou Holdings "Kabu" (Kurodou Katana)] Densha no Naka de Otokonoko to Sex Suru Hon

A short‑haired boy in a school swimsuit is cornered by an older, lecherous man on a train, leading to a forced and humiliating encounter that builds tension with each invasive demand. The scene escalates as the man overwhelms the boy with his weight, prompting frantic protests and comic exclamations, before the narrative abruptly shifts to a lighthearted conclusion where the boy, now in a hoodie, enjoys a bowl of ramen and declares the experience "pretty tasty" as a "Happy End" appears.
