They dont have much in terms of body tbh, they're pretty, yeah, but either they dont have much to offer in terms of curves (it often looks a bit boney, is that even a word?) or they settle for the bare minimum in terms of quality, or both. IMO they're a big Nothing Burger, they just like to make a quick buck from their simps while they can (the scarcity of italian mainstream/famous Onlyfansers might be a factor too). Idk tho, just a quick tought.
Just to be clear, there's nothing wrong with having a very slim and petite body (as long as it doesnt become pathologic), actually i am a big fan of it, but damn if you gotta open an OF/Patreon/whatever at least either get a nice ass or play smart and use poses/lighting; they dont do either.
