The clip is displayed on a poly-screen, with a close-up shot on the left and a wide shot on the right.
Well, Arina and Foxy attentively worship Astrid’s feet. Arina is lying on a table in ‘the pose’, while Foxy is kneeling with her hands tied behind her back and bare feet bound. Foxy also has to keep her toes pointed as much as possible.
One could say that they are doing this as considerate slaves for Astrid, but she is also bound. Her hands are tied behind her back with rope, and her feet, bound at the ankles, are fastened to a stand where her bare feet are positioned.
In this case, it would be more accurate to say that all three girls are submissive and are doing this for your pleasure, as they are also enjoying it themselves.
