tag for panty pull thing

to keep it brief, i'm looking to create a tag for this as far as i'm aware untagged trope where a female character pulls down her panties around her thighs for another character to then ejaculate directly onto. the closest approximate search is panty_pull (male_masturbation or futanari_masturbation or handjob) -solo, but that has endless false positives.

if that doesn't explain it, i've prepared favgroup #56510 with posts that i think would fit the tag.

the issue comes with picking a name. i was working with masturbating into panties for the favgroup name but that doesn't quite cut it since it can be done with a handjob too.

Ejaculation into panties would hit handjob/paizuri etc

perhaps this could be two tags - masturbation onto panties and handjob onto panties. this would skip the need to overcomplicate the naming and possibly even be better for searching.

(although i can picture someone using a tag named masturbation onto panties on a male_masturbation solo unworn_panties post, but i want to resist the urge to bikeshed...)
