The frogtie is a bondage position in which a person's legs are bound ankle-to-thigh, in the likeness of a crouched frog. The wrists on each side are often then tied to the ankle/thigh combination on their respective sides, although it is possible to tie each wrist to the opposite ankle and make the position noticeably more strict.
I say it in the title, it is a compilation only, an it is for show to all a clasification of a bondage style named frogtie, i dont say that the pictures have inedit... I Hope the people understand that sex rules are not ruled by humans without vision only :D
