The bulk update request #11705 is pending approval.
create alias cumming_onto_feet (63) -> cum_on_feet (12203)
create alias cumming_on_feet (3) -> cum_on_feet (12203)
create alias cumming_on_paws (1) -> cum_on_feet (12203)
create alias ejaculating_on_feet (8) -> cum_on_feet (12203)
Reason: Pretty much equivalent tags.
The only case in which they may be validly distinct from cum_on_feetis when a character is visibly in the process of cumming on feet - but that can be filtered with cum_on_feet ejaculation or similar combinations, and so I don't think it requires a separate tag.
