second thought,
looking over the content drop the current sponsors for paysites/cams/dating that match your most popular content themes.
would prob not rely on banner to drive sales but maybe work sales text into your indiviual posts.

maybe add sales text or banner to individual posts to related paysites - in this case some "dad fuck teen" or "Babysitter" thing.
can find sites and niches here:

maybe switch the banners to phone sex. would prob work best.
