Libertine: King of Hearts [Final] By Hasnotalent Media

The developers describe the content like this:

• Full nudity and explicit depictions of consensual sexual acts (player may choose to censor all nudity and fade to black sexual acts from the settings menu)
• Some sexual scenes include consensual BDSM and bondage elements, including your partner being handcuffed to a wall, being in a pillory, or referring to the player as “master.”
• Some sexual scenes include what appears like blood coming from a vampire-looking character’s mouth, which can be disabled during the scene (this is the remnants from consuming a fictional drug)
• Some sexual scenes involve being under the influence of drugs or alcohol
• Some sexual scenes include explicit degrading dirty talk between your partners, but not from the player towards them (voices can be disabled by the player during sexual scenes)
• One sexual scene involves degrading remarks towards the player character, such as calling him a “worthless dog.” (voices can be disabled by the player during sexual scenes)
• Some sexual and non-sexual scenes involve the player being referred to as “dog,” “plaything,” “pup,” “good boy,” etc. The non-sexual scenes involving this can be skipped or the voices muted but the player would miss story information.
• Non-sexual depictions of implied torture (aftermath is seen but not the act itself)
• Graphic depictions of suicide
• Graphic violence and gore including medical experimentation and surgery
• Use of illicit fictional drugs
• Tobacco use and alcohol use
