An example would be like LALS-008 (the one with shiori koto) where it’s split into two parts, a soft core gravure “shoot”, that slowly becomes more lewd with a “secret” B-side video that has the hardcore stuff (pretty much most of the LALS titles I can recall. As for the latter category, an example is GRP-003 with Arisa Mirai, where two thirds into the video (the blue swimsuit segment) she has an accidental nipslip, despite the rest of the video being so risqué.
