Daily expansion of the anus of a beautiful office worker with a large buttocks discovered on a crowded train! The anus, initially tight, was gradually loosened through expansion over 2-3 days! Transformation into a pervert with fluids leaking from a completely expanded and loose anus! A must-see is the sight of a large penis deeply inserted into the anus, with the person revealing their face and becoming aroused!




















The situation is set on a 'crowded train,' but it eventually moves to a location outside the train. Well, there are limitations on camera work and the actors' movements if it's set inside the train, so it's unavoidable. However, if you make the outside-of-the-train part too long, it deviates from the title. The portion filmed inside the train set gets extended, and honestly, do people really want to watch the 'dirty' parts repeatedly for a long time? I think keeping the train interior to a single day's length, with each actress getting about an hour, totaling around two and a half hours, would prevent it from feeling drawn-out. Kozue-san's thighs and butt are still amazing, though.
You finally get to see the 'poka-poka' in the last hotel scene. I don't think this manufacturer has ever had an anal scene before, but they included one this time.
