She just appeared as Mairy at MetModels:

Also, I *think* that Masha at Rigin-Studio is the same model:

She has a mole at the top of her right thigh, not far from her pubes, that makes her easy to identify. Unfortunately, I haven't been able to find any samples of the Rigin-Studio sets, so I can't verify that those sets are of the same model. If someone could find pics from those sets, that'd be great!
