barely visible balls

Explicit Tag
^{See Help: Ratings for more info.}

Posts where the balls are not obvious in the thumbnail, and remains difficult to see when viewing the actual post. This may be due to its small apparent size, being a similar color to the surroundings, or being partly covered up (by anything).

This tag does not apply if the balls are actively being interacted with.
This tag applies if any character's balls are barely visible, and can be used even if another character's balls are fully visible.
If the balls are fully covered up, use bulge or balls_outline where appropriate.
