The last one he put out of her was after they had already broken up, so I don't think he's against dropping them now or later, but he might also go in the other direction and release them more sporadically since they wouldn't be collabing the same as they used to, never really can guess this dude's business strategies lol.
When I asked him though, he said he had more with her, and in the description to her last drop's trailer or post itself, he said he'd send more of the stuff with her. Who knows when, but he set the precedent already by dropping the last one while she was with her current s/o, so no point in holding out.
My advice is to just spam his DMs with your most wanted collab requests if you ever do subscribe. He has a messaging function on the main website as well iirc.
Currently subscribed to the main site and I was planning on doing the photosets while I was, so I'll get to those eventually. Will/would probably be in zip form.
