I just discovered that Riley is getting her own site later this year:
Also, here's an overview of her photo and video sets from SF Bay Models:
And I found a couple more modeling profiles under her real name, Erica Mucci:
The Platinum Allure profile is especially intriguing; it says that Riley/Erica is interested in pursuing "adult performer" work. Before everyone gets all hot and bothered, it doesn't look like she's doing any hardcore (besides g/g with Sara) but she does check the boxes for domination, fetish, and bondage. BDSM isn't necessarily my thing, but I bet she'd be cute doing some light fetish.
