Looking for vintage Japanese softcore title and others like it.

I watched this when I was a kid. Want to know the actors, title, and other movies like it. Plot about a man cheating on his wife while she is out of town with his coworker and ends up getting more than he can handle when she wants more out of the relationship. Kind of like fatal attraction. Movie was Japanese dubbed in Chinese. Looking for sites to see watch more of these type of movies.
