The sellyourgf vid is the worst i've seen with her so far. It looks to be a Russian made vid and as such has poor quality control. It's also "plotted," which for me makes it close to a low comedy.
Anyway, the vid doesn't take advantage of her specific skill-set (amazing limberness) and either she had a few extra pounds on at the time of the shoot or the camera angles
make her look a little chunky or both.
