The intense face-to-face handjob in the crowded train's confined space left me breathless. The tension of close contact from the front amidst the chaos made the climax in an immobile situation even more erotic. The fierce, string-pulling deep kiss that steals the lips without allowing a moment of afterglow is truly breathtaking. The way rationality melts and hips writhe in heat with the line 'I'm getting wet from kissing...' is so arousing that even I, as a viewer, felt the heat. The development where the four actresses—Goba, Misakine, Minato Haru, and Umeda Minami—descend into sex madness while indulging in intense tongue kisses is nothing short of gripping. The tongue kiss scenes, in particular, stand out for their eroticism, with the interplay of sucking and licking reaching an artistic level. The direction that achieves such intimate contact in a public setting like a train is commendable. The performances highlighting each actress's personality are also a highlight: Goba's boldness, Misakine's sensuality, Minato Haru's delicacy, and Umeda Minami's frenzy add depth to the work. Overall, it's a masterpiece that skillfully blends excitement from an extraordinary situation with realistic emotional portrayal.
