In some anal only and anal fetish scenes, female performer will have some kind of tape covering their vagina, so that only the anus can be used. For example: ( StashDB 66e89979-fbc2-47d1-80eb-dc0312353ab3).
Closest I’ve found is tag “Anal Sex in Chastity” but that seems to refer more to male anatomy.
Edited to add proposed name and description:
Name: Taped pussy
Description: Female performer has tape or other covering over their vagina to encourage anal only sex.
Aliases: Blocked pussy, covered pussy
