We won't know until someone buys it, which I probably won't be doing anytime soon given there's no previews.
As for Brandon, I can understand why he wouldn't want to do a solo onlyfans. If you're a guy, there's a difference between having a solo and a b/g OF link on your social media page. He probably doesn't want people thinking he's one of those types of guys showing his hole, using toys and asking for tips for cock ratings, given how passionate he seems about his career. It's an image he doesn't want to be associated with and feels more comfortable with people realizing it's him and his girlfriend together.
He doesn't want to look like he's catering to a specific audience in other words. This is as good as it's going to get with him, and seeing what has been posted so far on their page with him, I can guarantee none of those pics would've ever seen the light of day without their couple page.
