Ingrid - Bondage, cane on the feet, iron nails and spur on the soles

I have Ingrid tied up in "The Pose", because this woman has very sexy soles, and this way I can explore her feet better.
The soles are pink, a little wrinkled and this excites me. Ingrid is completely immobilized and her small, thin body is easily moved by me.
I start with tickling, but Ingrid is not very sensitive to them. So I start to bring a little pain to those soles with the iron nails and the spur.
It is a domination focused on the feet, but I will not miss the opportunity to crush her tits with my hands, among other painful details.
I will also use the cane to cause pain in her soles before leaving her confused and in the dark.
