When a series makes it to Volume 15, you know they are doing something right. I’ve reviewed several of these, and have found very little wanting. What you typically get is several vignettes which all involve sex in an office setting. What sets this series apart in my mind is how much fun the performers have in acting out their scenes. They tend to not be too serious, but it is enough to make the plot aspects somewhat enjoyable. In fact, there is usually more plot in a Naughty American title than your typical “plot” driven feature.
