thanks for sharing ...wonderful pics ...its apparent both you and your wife are on the same wavelength when it comes to the subjects of bondage and tickling ..believe me you are one lucky SOB
I love your clips and they are among the best out there. If I were to make any suggestions, it would be to make it so Meka cannot untie or ungag herself and that she is sat in a position where she has to watch what you're doing (at least until you blindfold her to increase the tension... ).
Set 6 does this as she wouldn't be able to get out of that and has to sit forward (the other position I thought of was to use a collar fastened to the front of the chair and to handcuff hands behind back).
Should you guys ever have an evening with nothing to do, please feel free to make a video of this! ;-)
