I totally love it too! Tape gags are awesome! Especially if it's strips of duct pae xD! I know that wraping around the head is more effective, but I like how handsome a bound and helpless boy can be with strips of duct tape in his mouth. And this folowing picture, is one of me favorites ;D!
Look how helpless and cute he is! Also, I bet he has no idea of what is written on his gag xD! Suck a helpless, gagged and blindfolded slave ;D!
EDIT: Hey, guys! I did found the link for the owner of this picture!
