I remember seeing this in a fj compilation vid,it looks really good too,the guy is clearly enjoying it,i think she makes him explode with her feet. Also found it at The Mousepad Wanted section:
I'm looking for the Myndi Fox (from Feeture) footjob clip she performed on the guy who was laying down and squirming a lot. She finishes him off with her hands. It's quite rare. The promo has been floating around for years, but the full clip is nowhere to be found.
