Asesino en serio

I have been viewing a few Italian sex comedies, and found this little gem - a Mexican sex comedy.

Comandante Martínez (Jesús Ochoa - Nicotina) is investigating a string of murders where all of the women have a big smile on their face. They died very happy. What's the coroner say - they died in the throes of major orgasm! Outside of Ochoa, the main attractions of the movie are the extremely attractive women that get murdered.

He does solve the crime, and manages to get rid of some problems with his new found luck. He even manages to perfect the technique to his everlasting advantage.
