A slender, well-dressed office lady with a beautiful butt starts a continuous series of lewd encounters triggered by a meeting on the commuter train! "The office at work," "the ryotei visited for entertainment," "the yoga class she attends for a hobby," etc. As days go by, she loses her escape routes and her sensitivity skyrockets! Eventually, she falls into the pit of 'dangerous pleasure' and boards the train where the lewd master awaits... Her beautiful buttocks twitch as she surrenders to the relentless 4SEX!
