Riko Hoshino is a part-time worker at the same sports shop. One day after closing, while we were both doing inventory, I missed the last train and ended up staying at Riko's place. Riko stubbornly refused to take off her makeup, which I found adorable and it turned me on. I confessed, "I've liked you for a long time." What started as a bit of mischief ended up with me being drained all night.
