What is the fetish called where a futa is trying really hard to be chaste and not do anything lewd, but gradually over the course of days/weeks the tension builds up and she gets hornier and hornier until she finally loses it?
Because that's my fetish.

There's no explicit tag for it. However, on exhentai it frequently shows up in conjunction with a tag called "corruption" or, alternatively and rarely, "moral degeneration". To narrow your search further, include "incest".
