Used for posts depicting penetration involving a character's mouth.

Penetration includes most combinations of body parts and objects, and is usually considered a form of sex or masturbation.

• This does not include fist/paw/hoof/arm/etc. For this use oral fisting instead.
• This does not include fingers. For this use finger in mouth, or oral fingering if the fingers are used in a sexualized way similar to other fingering tags.
• This does not include objects being held in the mouth. For this use mouth hold instead.
• This does not include gags. Penetrative gags are a grey area, and might count.
• This does not include eating. This tag may be used if the object could pass as an improvised sex toy. See food insertion

This is most likely going to be a form of fellatio, or autofellatio, but keep in mind that those tags only apply to penetration involving a penis. Penetration involving other appendages or objects have their own "fellatio" related tags that should be used in addition to this tag.
