In my humble opinion this clip is horrible.
I enjoy women tickling women's feet and I find the use of a blanket as restraint fine, but this clip disappointed me.
Seeing the way the tickler diggs - or rather thrusts - her nails into the flesh of the ticklee's feet is not very appealing and the sound the ticklee is making cannot be called laughter. If someone would hear her without seeing the pictures this scene might probably seem to be real torture and not tickling.
I would love this clip, if the ticklee would be laughing, maybe even enjoying it. The tickler should try using a slower or milder tickling method. An index finger gently moving up and down the sole can be effective and arousing, too.
Nevertheless, thanks for posting the pictures and the preview. And please keep in mind that this constructive criticism is only my personal point of view.
Regards
