It is what it is because she never wants to operate outside of her comfort zone. She will do this for as long as she can make money off it.
She's not like the true horny types who have to show how far they'll go or someone who gives any care about differentiating her videos.
Since the start she's likely always been comfortable financially which insulates any drive money wise or creatively to do anything different. Everything about her screams safe, content, and comfortable.
