Julia-Eva wears a pair of bottines with thick, but edgy, heels and a sole with crazy edgy profile.
And with this "tools" she want to deform her slave, giving him a new design and skin color.

The edges of the heels give nice scratches and imprints, and the profile of the sole cuts deep stripes....
and her impressive weight fullfills the painful procedure.
