maitland had several years of teasing, then started doing bodypaint, then softcore nudes, and then eventually, after years, did start doing porn. It wasn't immediate.
But yes the fact is that many that do this sort of thing start without the goal of getting naked, but as soon as they see the money rolling in, some of them will play around with teasing more and more before they decide to eventually go all in. With celebrities, it's obviously a higher bar before they might consider doing that, but it's still not impossible.
Megan has a recent history of already teasing in photoshoots and social media as well as this new ad, so she may actually be in a good space to be open do doing more on a site like this, especially since she's part owner of the site. But time will tell.
