The tag implication #60327 oversized_fellatio -> fellatio is pending approval.

Reason: it's in the name of the tag

(please don't delete this tag, by the way -- it refers to characters that are much larger performing the act, there isn't really a better tag for that, and I think it can reasonably be kept clean)

oversized_fellatio doesn't seem to be a very clear tag name. My first thought was fellatio on an oversized/too-large penis. It seems closer to fellatio+larger_penetrated, other than the fact that not all fellatio is penetration...
