Extremely beautiful secretary being raped by her boss

Marina Shiraishi and her husband work at the same company as boss Abe. He is a lustful and love-crazy old man who always pays attention to Marina and is always jealous of her husband. Marina's husband makes a mistake at work and is being reprimanded while Marina is promoted to be his secretary. Abe's lustful behavior soon became apparent when he and Marina were in the same room. It was humiliating and embarrassing to have sex with Abe, so Marina always felt guilty, but the attraction of sex was so great that she couldn't do otherwise.
