Off Topic Porn where the girls try not to orgasm?

[TheAnyKeyGertrude]

Porn where she is stimulated by a partner(b/g), attempting to make her cum but she tries her hardest not to go over the edge and succumb to the orgasm. E.g. evolvedfights, orgasm challenge or Clara Dee's Clara Tries Not To Cum - Chapter 4 Unfair Dismissal With Sarah Vandella. I like that playful, competitive aspect. Who first cums "loses."

Is there a term for that niche? I can't find much, maybe I need better search terms.

Thanks.
