Maybe never. She'll make so much off people just by putting out full nudes, she won't have to do more than that. Too many people paying 150 for one pic.
Which is to probably say never. I think she still has one fight left on her BKFC contract, and she's looking to re-sign there, but she also lost every fight, so.... If she does any sex tapes, it'll way too far into the future.
