Bouken Shite mo Ii Koro

Two comedies taking place in the porn production industry. In both the framing device is a newcomer to the industry who learns on the job. Both have a similar humor, which plays with the sober and professional approach to ... producing smut for money. Both anime take the time to at least superficially introduce an ensemble cast to showcase the different professions. Animation wise they are over 20 years apart, with Bouken Shite being low budget even at it's time. Yet, they share roughly the same degree of ecchiness and humor.
