I don't mind if Mila never does b/g, but seeing her do some lesbian stuff would be awesome. The website where she masturbated with another model was Yonitale, but I don't think it exists anymore.
The Yonitale content dates back to early 2017. At that point, Mila had been modelling for only one year. It's a shame she didn't do more, because the website had plenty of lesbian content, so the opportunity was there.
She also modelled for Disciples of Desire, which mostly does interracial b/g, but she only masturbated, as usual.
