Meister Sem Und Seine Sklavin, 112 min

A blonde rubber clad dominatrix works over a submissive couple. She ties them up before administering a sound paddling. She then treats them to a little electro-stimulation. She's not completely heartless, she does allow them to go down on each other and even brings the woman to orgasm with a vibrator. Things get a little wild at sea when a master binds and spanks his submissive on the deck of the ship. They then go below for more exquisite tease.
