At my workplace, I'm always being yelled at by a female chief (28 years old). But I've kept it a secret from my colleagues, because in fact, my boss Okuda-san is my girlfriend... During the day at the office, she's a strict S-type boss to her subordinates, but at night at home, she transforms into a submissive and spoiled M-type. She engages in lewd, nymphomaniac sex, even having sex with a close friend behind my back... The reversed relationship between boss and subordinate, girlfriend and boyfriend, accelerates with desires for sex. Inside my girlfriend's heart, a witch and a goddess coexist!
