Shuuden Nogashita Gal ga Maid Bikini de Gohoushi Ecchi shite Kureta Hanashi

Arima is a quiet, introverted college student who prefers spending his evenings alone. His peaceful routine is abruptly interrupted when Nishimiya Koharu, a flashy and outgoing girl from his college club, arrives at his door visibly intoxicated. Having missed the last train home due to her drunken state, she has nowhere else to go and ends up staying the night at his apartment. What begins as an awkward situation quickly escalates when Koharu starts exploring his room. She stumbles upon his collection of adult magazines and, to Arima’s absolute horror, discovers a maid bikini costume he had secretly purchased with the naive hope that a future girlfriend might wear it for him. Bracing himself for judgment and disgust, Arima is stunned when Koharu cheerfully offers to put the outfit on, finding the idea amusing. The sight of Koharu’s voluptuous figure clad in the revealing maid bikini leaves Arima instantly aroused. Fueled by alcohol and playful enthusiasm, Koharu decides to thank him for his hospitality by fully embracing the role. Declaring that she will "serve" him as his personal maid, she initiates an unexpectedly intimate evening, turning Arima's quiet night into something far beyond his imagination.
