My boss, Miyu-senpai, always wears a short, tight skirt that's bursting at the seams. On top of that, her ass is so huge that I can't help but have erotic fantasies during work... Then, Miyu-senpai asked, "Are you that interested in my ass?" and let me touch it! If only there were a senior at work who was usually strict but would seduce me like this... This is a situational work that makes that fantasy come true!
