You would need to purchase their 'yellow buzz' currency, it should be somewhere in your profile. There are also subscriptions that you can buy
There are also various similar resources online, but nothing that I can recommend off the top of my head. Some probably have a limited free option for NSFW stuff, but that stuff changes often, so you would have to search for that.
Another option is to download the model (from civitai or any other website, this specific model can be found in different places). This would require a good PC, and I would not be able to give any advice on that since I haven't used it that much.
In any case, good luck!
