Contests, etc. Below, we've listed the actions that will raise or lower this stat to help you plan out your actions.
- This stat is called Fuck in older versions.
- If this stat is limited, you must use XXX to raise it beyond the limit. Serving as a demonstration model for the Owner of the XXX School or joining Miss N at her Sex Party also increases maximum Fucking.
- This stat will be replaced by Trib/Strap-on if you are going for the Lesbian Slave ending.
