Implicating deep_rimming → anal_penetration
Link to implication

Reason:

By definition, deep rimming is a version of insertive oral and anal sex.

EDIT: The tag implication deep_rimming -> anal_penetration (forum #250428) has been rejected by @NotMeNotYou.

If this (deep_rimming → anal_penetration) does get approved,
how about adding penis_in_ass as a tag?

(since dildo_in_ass is one of the tags that implies to anal_penetration
.... along with pegging, double_anal, and triple_anal.

and since we have limit of how many tags to use in search.)
