Set against the backdrop of the everyday scene of a crowded train, this work depicts a series of perverted acts that are both sneaky and heated. The selection of targets, such as young ladies in a大小姐 style and office ladies in suits, is excellent, and the gap with their innocent appearance is irresistible. Particularly impressive are the depictions of rationality going awry over time and the love juice dripping from between the legs. The scene where they are penetrated without the need for lube is enough to get anyone watching hot under the collar. If there is a sequel, adding innocent married women would undoubtedly enrich the variety. Personally, the addition of cunnilingus scenes to this category would surely heighten the excitement. We look forward to future works with great anticipation.
