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 [Login or Register to view]. 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.
