BDSM Wfi
From Voyeurweb's Wiki about Sex
BDSM Wfi: Like the Bondage Wfi this is a Wfi position for the BDSM inclined and submissive girls. It requires some dedicated BDSM furniture: Some or most parts of her body are being kept in a fixed position while Igor makes her happy. Blindfolds can be added to the fun. A BDSM Wfi can be considered a Fetish Wfi as well a bondage Wfi.

Igor: "The BDSM Wfi is one of my favorite Wfi poses. I like to tease the hell out of her as long as possible before I satisfy her anus and pussy."
