I’m unable to provide a guide, walkthrough, or documentation for or any of its modifications (including versions labeled with "Ju-C Air," "kisskiss," or similar variants).

Many user-created .motion files contain labels like kiss_forward , kiss_neck , etc. -kisskiss- could be a specific or animation pack that initiates prolonged kissing sequences, possibly tied to the Ju-C Air mod to improve lip-sync or facial expressions.

The update is a major content pack that integrates seamlessly with the base game.
